Abstract
<div><h4>Outcomes of concomitant surgical ablation in patients undergoing surgical myectomy for hypertrophic obstructive cardiomyopathy: A systematic review and meta-analysis.</h4><i>Kharbanda RK, Ramdat Misier NL, Van den Eynde J, El Mathari S, ... Palmen M, Klautz RJM</i><br /><b>Objective</b><br />Studies investigating the efficacy of concomitant surgical atrial fibrillation (AF) ablation in hypertrophic obstructive cardiomyopathy (HOCM) patients undergoing myectomy are scarce and limited in terms of sample size. We aim to summarize current outcomes of concomitant surgical AF ablation in HOCM patients undergoing surgical myectomy.<br /><b>Methods</b><br />This systematic review and meta-analysis was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included all studies reporting any of the following outcomes of concomitant surgical AF ablation in HOCM patients: freedom from recurrence of AF, overall survival and complications. Outcomes were evaluated using traditional meta-analysis at given time-points and using pooled Kaplan-Meier curves.<br /><b>Results</b><br />A total of 13 studies were included, resulting in a total of 616 individual patients available for analysis. AF was paroxysmal in 68.1% of the patients (95% CI 56.0-78.2%; I<sup>2</sup> = 87.1%; 8 studies, 583 participants). The majority of patients (86.2%) underwent either conventional Cox Maze III or IV (95% CI 39.7-98.3%; I<sup>2</sup> = 92.4%; 8 studies, 616 patients) procedure. The incidence of early post-operative pacemaker implantation was 6.1% (95% CI 3.1-11.8%). Overall survival at 3, 5 and 7 years was 95.6% (95% CI 93.4-97.9%), 93.6% (95% CI 90.8-96.5%) and 90.5% (95% CI 86.5-94.6%), respectively. Freedom from recurrent AF at 3, 5 and 7 years was 77.6% (95% CI 73.7-81.7%), 70.6% (95% CI 65.8-75.7) and 63.2% (95% CI 56.2-73.8%), respectively.<br /><b>Conclusion</b><br />This meta-analysis supports concomitant surgical AF ablation at the time of surgical myectomy in HOCM patients, as it seems to be safe and effective in terminating AF.<br /><br />Copyright © 2023.

Abstract
<div><h4>Deactivation of implantable defibrillators at the end of life - A register-based study of ICD-deactivation at home and the impact of palliative care.</h4><i>Höijer CJ, Johnson MJ</i><br /><b>Background</b><br />The Implantable Cardioverter-Defibrillator (ICD) is a well-established life-saving therapy for heart failure patients, but due to the risk for unnecessary shocks, deactivation of ICD:s is recommended at the end of life. We aimed to identify i) how many people with HF and an ICD who died in Sweden in 2018 received Specialized Palliative Care (SPC), ii) of those dying outside of hospital, the proportion with deactivated ICDs prior to death for the group as a whole and by SPC access.<br /><b>Methods and results</b><br />We analyzed data from i) the Swedish ICD and Pacemaker Registry to find all who died with an ICD in Sweden in 2018, ii) the Swedish Register of Palliative Care and, iii) the Swedish Causes of Death Certificate Register to find those who died outside of hospital. Clinical records were obtained to assess if ICDs were deactivated before death. Descriptive statistics, t-tests and chi-squared tests were applied. 46/406 (11%) of those who died with an ICD in Sweden in 2018 had SPC access, of whom 50% also had cancer. 86/164 (52%) ICDs were deactivated prior to death in people dying outside of hospital; higher in those accessing SPC (36/46, (78%) SPC access versus 151/360, (42%) no SPC access; p < 0.05).<br /><b>Conclusions</b><br />Half of those with HF and an ICD dying outside of hospital had ICD deactivation prior to death. Those accessing SPC were more likely to have their ICD deactivated but few received SPC, without a comorbid cancer diagnosis.<br /><br />Copyright © 2023 The Author. Published by Elsevier B.V.

Abstract
<div><h4>Arrhythmic and thromboembolic outcomes in adults with coarctation of the aorta.</h4><i>Shadarevian J, Zhu K, Kwan JM, Wan D, ... Sathananthan G, Chakrabarti S</i><br /><b>Background</b><br />Adults with congenital heart disease (ACHD) experience a high prevalence of atrial arrhythmia (AA) and thromboembolic cerebrovascular complications. However, data on AA and associated long-term outcomes are limited in ACHD patients with coarctation of the aorta (CoA).<br /><b>Objectives</b><br />This study aimed to characterize the prevalence and risk factors for AA and thromboembolic complications in adults with CoA.<br /><b>Methods</b><br />We conducted a retrospective cohort study in a tertiary ACHD care center and included consecutive CoA patients older than 18 years old with more than one year of follow-up.<br /><b>Results</b><br />Two hundred seventy patients with CoA were followed for 7.2 ± 3.95 years. The mean age was 35.3 ± 11.1 and 55.2% were male. Patients had a mean of 2.1 ± 1.8 cardiovascular surgical or transcatheter procedures. Thirty-five patients (13%) had AA. Ten subjects (3.8%) had a thromboembolic cerebrovascular event, of which four (1.4%) had AA. In univariate analysis, age (p = 0.005) and total intracardiac interventions (p = 0.007) were associated with the presence of AA. Age (p = 0.021), history of heart failure (p = 0.022), and dyslipidemia (p = 0.019) were associated with thromboembolism. In multivariate analysis, age (p < 0.001) and intracardiac interventions (p = 0.007) were associated with AA.<br /><b>Conclusions</b><br />The rate of AA is higher in adults with CoA than in the general population but lower than in other ACHD. Increasing age and intracardiac interventions were associated with AA. The rate of thromboembolic events was low. Some traditional risk factors for stroke may apply. Larger studies are needed to validate predictors for stroke in this population.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

Abstract
<div><h4>Effect of prior anticoagulation therapy on stroke severity and in-hospital outcomes in patients with acute ischemic stroke and atrial fibrillation.</h4><i>Zhou L, Li Y, Yang X, Gu H, ... Wang C, Wang Y</i><br /><b>Background</b><br />We aimed to assess the prevalence of prior anticoagulation therapy (warfarin or non-vitamin K antagonist oral anticoagulants [NOACs]) among patients with acute ischemic stroke (AIS) and atrial fibrillation (AF) in China and investigate the associations between prior anticoagulation therapy and initial stroke severity and in-hospital outcomes.<br /><b>Methods</b><br />We included consecutive patients with AIS and known history of AF admitted to hospitals in the China Stroke Center Alliance (CSCA) program from January 2019 to July 2019. Multivariate logistic regression analyses were performed to determine the associations between prior anticoagulation therapy and initial stroke severity and in-hospital outcomes.<br /><b>Results</b><br />Of 7181 patients (median [IQR] age, 75.0 [68.0-81.0] years; 48.7% men), 700 (9.7%), 129 (1.8%), and 255 (3.6%) patients received prior subtherapeutic warfarin (international normalized ratio [INR] <2.0), therapeutic warfarin (INR ≥2.0), and NOACs therapy, respectively. A total of 6499 patients had a preadmission CHA<sub>2</sub>DS<sub>2</sub>-VASc score ≥ 2, among whom 94.6% were not adequately anticoagulated. Compared with no prior anticoagulation therapy, prior NOACs therapy was associated with reduced risk of moderate or severe stroke at admission (odds ratio [95% CI], 0.64 [0.43-0.94], P = 0.023) and in-hospital mortality or discharge against medical advice (DAMA) (0.46 [0.24-0.86], P = 0.015). However, no significant association was observed between prior therapeutic warfarin therapy and stroke severity or in-hospital mortality or DAMA.<br /><b>Conclusions</b><br />Among patients with AIS and AF in China, the proportion of patients with inadequate anticoagulation prior to stroke remained substantially high. Prior NOACs therapy was associated with reduced stroke severity and less in-hospital mortality or DAMA.<br /><br />Copyright © 2023.

Abstract
<div><h4>Coronary artery disease is associated with impaired atrial function regardless of left ventricular filling pressure.</h4><i>Sharifov O, Denney TS, Girard AA, Gupta H, Lloyd SG</i><br /><b>Background</b><br />Left atrial (LA) strain is impaired in left ventricular (LV) diastolic dysfunction, associated with increased LV end diastolic pressure (LVEDP). In patients with preserved LV ejection fraction (LVEF), coronary artery disease (CAD) is known to impair LV diastolic function. The relationship of LVEDP with CAD and impact on LA strain is not well studied.<br /><b>Methods and results</b><br />Patients with LVEF >50% (n = 37, age 61 ± 7 years) underwent coronary angiography, high-fidelity LV pressure measurements and cardiac magnetic resonance imaging. LA volumes, LA emptying fraction (LAEF), LA reservoir strain (LARS) and LA long-axis shortening (LALAS) were measured. By coronary angiography, patients were assigned into 3 groups: severe-CAD (n = 19, with obstruction of major coronary arteries >70% and/or history of coronary revascularization), mild-to-moderate-CAD (n = 10, obstruction of major coronary arteries 30-60%), and no-CAD (n = 8, obstruction of major coronary arteries and branches <30%). Overall, LVEF was 65 ± 8% and LVEDP was 14.4 ± 5.6 mmHg. Clinical characteristics, LVEDP and LV function measurements were similar in 3 groups. Severe-CAD group had lower LAEF, LALAS and LARS than those in no-CAD group (P < 0.05 all). In regression analysis, LARS and LALAS were associated with CAD severity and treatment with Nitrates, whereas LAEF and LAEF<sub>active</sub> were associated with CAD severity, treatment with Nitrates and LA minimum volume (P < 0.05 all). LAEF<sub>passive</sub> was associated with LVED volume (P < 0.05).<br /><b>Conclusions</b><br />LA functional impairment may be affected by coexistent CAD severity, medications, in particular, Nitrates, and loading conditions, which should be considered when assessing LA function and LA-LV interaction. Our findings inspire exploration in a larger cohort.<br /><br />Copyright © 2023. Published by Elsevier B.V.<br /><br /><small>Int J Cardiol: 29 May 2023; epub ahead of print</small></div>

Abstract
<div><h4>Nocturnal pulse wave amplitude attenuations are associated with long-term cardiovascular events.</h4><i>Shahrbabaki SS, Linz D, Baumert M</i><br /><b>Objectives</b><br />Photoplethysmography (PPG) is an established technology for detecting pulse rate and pulse wave irregularities. However, whether temporal variations in pulse wave amplitudes, reflecting a combination of acute hemodynamic or autonomic responses to changes in overall vascular function, carry prognostic information remains unclear. To quantify nocturnal temporal pulse wave amplitude (PWA) attenuations and evaluate its association with long-term cardiovascular (CV) events in a large, racially diverse sample of men and women.<br /><b>Methods</b><br />Temporal PWA attenuations were determined based on the slopes between the upper and lower envelopes of PPGs derived from overnight polysomnography of 1957 participants (899 men, 1058 women, mean age 68.2 ± 9.1 years) of the Multi-Ethnic Study of Atherosclerosis. The nocturnal PWA attenuation index was defined as the cumulative duration of all PWA attenuation events relative to total sleep duration.<br /><b>Results</b><br />Nocturnal PWA attenuation index was greater in men than in women by almost 13% (16.3 ± 8.9% vs. 14.4 ± 7.9%, p < 0.001). The nocturnal PWA attenuation index was highest in Chinese-American participants (17.9 ± 9.2%) and lowest in African-Americans (13.5 ± 8.1%). During a median follow-up of 4.9 years, 94 CV events occurred. In multivariable Cox proportional hazard analysis adjusted for typical confounders, the nocturnal PWA attenuation index <15.2% was associated with CV events (HR = 1.58 [1.02-2.45], p = 0.042).<br /><b>Conclusions</b><br />Nocturnal PWA attenuation index is inversely associated with the risk of CV events, particularly in men and African-Americans. The PPG-derived nocturnal PWA attenuation index could be simply obtained from smart wearable consumer devices and may provide a low-cost, accessible and scalable CV risk marker.<br /><br />Copyright © 2023 The Author.

Abstract
<div><h4>WATCH-DM risk score predicts the prognosis of diabetic phenotype patients with heart failure and preserved ejection fraction.</h4><i>Zhang X, Lv X, Wang N, Yu S, ... Cai M, Liu Y</i><br /><b>Background</b><br />Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome. Diabetes may identify an essential phenotype that significantly affects the prognosis of these patients. The WATCH-DM risk score has been validated for predicting the risk of heart failure in outpatients with type 2 diabetes mellitus (T2DM), but its ability to predict clinical outcomes in HFpEF patients with T2DM is unknown. We aimed to assess whether this risk score could predict the prognosis of diabetic phenotype patients with heart failure and preserved ejection fraction.<br /><b>Methods</b><br />We enrolled retrospectively 414 patients with HFpEF (70.03 ± 8.654 years, 58.70% female), including 203 (49.03%) type 2 diabetics. Diabetic HFpEF patients were stratified by baseline WATCH-DM risk score.<br /><b>Results</b><br />Diabetic HFpEF patients exhibited a trend toward more concentric remodeling/hypertrophy than nondiabetic HFpEF patients. When analyzed as a continuous variable, per 1-point increase in the WATCH-DM risk score was associated with increased risks of all-cause death (HR 1.181), cardiovascular death (HR 1.239), any hospitalization (HR 1.082), and HF hospitalization (HR 1.097). The AUC for the WATCH-DM risk score in predicting incident cardiovascular death (0.7061, 95% CI 0.6329-0.7792) was higher than that of all-cause death, any hospitalization, or HF hospitalization.<br /><b>Conclusions</b><br />As a high-risk phenotype for heart failure, diabetic HFpEF necessitates early risk stratification and specific treatment. To the best of our knowledge, the current study is the first to demonstrate that the WATCH-DM score predicts poor outcomes in diabetic HFpEF patients. Its convenience may allow for quick risk assessments in busy clinical settings.<br /><br />Copyright © 2023.

Abstract
<div><h4>Comparison of oral anticoagulation by vitamin-K antagonists and non-vitamin-K antagonists for treatment of leaflet thickening after transcatheter aortic valve implantation (TAVI).</h4><i>Ferstl P, Achenbach S, Marwan M, Bittner DO</i><br /><b>Introduction</b><br />Hypoattenuated leaflet thickening (HALT), as identified by CT imaging, is not infrequent after transcatheter aortic valve implantation (TAVI). The best choice of oral anticoagulation is unknown. We compared the effectiveness of Direct Oral AntiCoagulants (DOAC) and Vitamin-K Antagonists (VKA) to resolve HALT in patients with serial CT aquisitions.<br /><b>Methods</b><br />A total of 46 consecutive TAVI patients in whom anticoagulation had been initiated because of HALT and who underwent follow-up CT were identified. Indication and type of anticoagulation was according to physician discretion. Patients on DOAC were compared to VKA therapy regarding resolution of HALT.<br /><b>Results</b><br />Mean age of the 46 patients was 80 ± 6 years (59% men), and the mean duration of anticoagulation was 156 days. Overall, 41 patients (89%) showed resolution of HALT with anticoagulation therapy, whereas HALT persisted in 5 patients (11%). Resolution of HALT was seen in 26 out of 30 (87%) patients receiving VKA and in 15 out of 16 (94%) patients receiving DOAC, respectively. Groups did not differ regarding age, cardiovascular risk factors, TAVI prosthesis type and size or duration of anticoagulation (all p > 0.05).<br /><b>Conclusion</b><br />Anticoagulation therapy resolves leaflet thickening after TAVI in most patients. Non-Vitamin-K antagonists seem to be an effective alternative to Vitamin-K antagonists. This finding needs to be confirmed in larger prospective trials.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

Abstract
<div><h4>Increased arterial stiffness elevates the risk of heart failure in diabetic patients.</h4><i>Wu L, Wu M, Zhang X, Chen S, ... Zhuang J, Hong J</i><br /><b>Background</b><br />Previous studies have shown that arterial stiffness (AS) was a risk factor for heart failure (HF) in nondiabetic patients. We aimed to analyze this impact in a community-based diabetic population.<br /><b>Methods</b><br />Our study excluded those who had HF before brachial-ankle pulse wave velocity (baPWV) measurement and included 9041 participants finally. Subjects were divided into the normal (<14 m/s), intermediate (14-18 m/s), and elevated baPWV groups (>18 m/s) based on baPWV values. Multivariate Cox proportional hazard model was used to analyze the effect of AS on HF risk.<br /><b>Results</b><br />During the median follow-up of 4.19 years, 213 patients had HF. The results of Cox model showed that HF risk in the elevated baPWV group was 2.25 times higher than that in the normal baPWV group (95% confidence interval [CI]: 1.24-4.11). HF risk increased by 18% (95% CI:1.03-1.35) for every 1 additional standard deviation(SD)of baPWV. Restricted cubic spline results showed statistically significant overall and non-linear associations between AS and HF risk (P < 0.05). The subgroup analysis and sensitivity analysis were consistent with that of total population.<br /><b>Conclusions</b><br />AS is an independent risk factor for developing HF in the diabetic population, and AS exhibits a dose-response relationship with HF risk.<br /><br />Copyright © 2023.

<div><h4>Late left ventricular myocardial remodeling after pulmonary artery banding for end-stage dilated cardiomyopathy in infants: An imaging study.</h4><i>Ponzoni M, Zanella L, Reffo E, Cavaliere A, ... Vida VL, Padalino MA</i><br /><b>Background</b><br />Understanding the macroscopic biventricular changes induced by pulmonary artery banding (PAB) in children with dilated cardiomyopathy (DCM) represents the first step to unraveling the regenerative potential of the myocardium. We herein investigated the phases of left ventricular (LV) rehabilitation in PAB responders, using a systematic echocardiographic and cardiac magnetic imaging (CMRI) surveillance protocol.<br /><b>Methods</b><br />We prospectively enrolled all patients with DCM treated with PAB from September-2015 at our institution. Among 9 patients, 7 positively responded to PAB and were selected. Transthoracic 2D echocardiography was performed before PAB; and 30, 60, 90, and 120 days after PAB; and at the last available follow-up. CMRI was performed before PAB (whenever possible) and one year after PAB.<br /><b>Results</b><br />In PAB responders, LV ejection fraction showed a modest 10% increase 30-60 days after PAB, followed by its almost complete normalization after 120  days (median of 20[10-26]% vs 56[44.5-63.5]%, at baseline and 120 days after PAB, respectively). Parallelly, the LV end-diastolic volume decreased from a median of 146(87-204)ml/m2 to 48(40-50)ml/m2. At the last available follow-up (median of 1.5 years from PAB), both echocardiography and CMRI showed a sustained positive LV response, although myocardial fibrosis was detected in all patients.<br /><b>Conclusions</b><br />Echocardiography and CMRI show that PAB can promote a LV remodeling process, which starts slowly and can culminate in the normalization of LV contractility and dimensions 4 months later. These results are maintained up to 1.5 years. However, CMRI showed residual fibrosis as evidence of a past inflammatory injury whose prognostic significance is still uncertain.<br /><br />Copyright © 2023.

<div><h4>Pre-test probability for coronary artery disease in patients with chest pain based on machine learning techniques.</h4><i>Choi BG, Park JY, Rha SW, Noh YK</i><br /><b>Background</b><br />A correct and prompt diagnosis of coronary artery disease (CAD) is a crucial component of disease management to reduce the risk of death and improve the quality of life in patients with CAD. Currently, the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC) guidelines recommend selecting an appropriate pre-diagnosis test for an individual patient according to the CAD probability. The purpose of this study was to develop a practical pre-test probability (PTP) for obstructive CAD in patients with chest pain using machine learning (ML); also, the performance of ML-PTP for CAD is compared to the final result of coronary angiography (CAG).<br /><b>Methods</b><br />We used a database from a single-center, prospective, all-comer registry designed to reflect real-world practice since 2004. All subjects underwent invasive CAG at Korea University Guro Hospital in Seoul, South Korea. We used logistic regression algorithms, random forest (RF), supporting vector machine, and K-nearest neighbor classification for the ML models. The dataset was divided into two consecutive sets according to the registration period to validate the ML models. ML training for PTP and internal validation used the first dataset registered between 2004 and 2012 (8631 patients). The second dataset registered between 2013 and 2014 (1546 patients) was used for external validation. The primary endpoint was obstructive CAD. Obstructive CAD was defined as having a stenosis diameter of >70% on the quantitative CAG of the main epicardial coronary artery.<br /><b>Results</b><br />We derived an ML-based model consisting of three different models according to the subject used to obtain the information, such as the patient himself (dataset 1), the community\'s first medical center (dataset 2), and doctors (dataset 3). The performance range of the ML-PTP models as the non-invasive test had C-statistics of 0.795 to 0.984 compared to the result of invasive testing via CAG in patients with chest pain. The training ML-PTP models were adjusted to have 99% sensitivity for CAD so as not to miss actual CAD patients. In the testing dataset, the best accuracy of the ML-PTP model was 45.7% using dataset 1, 47.2% using dataset 2, and 92.8% using dataset 3 and the RF algorithm. The CAD prediction sensitivity was 99.0%, 99.0%, and 98.0%, respectively.<br /><b>Conclusion</b><br />We successfully developed a high-performance model of ML-PTP for CAD which is expected to reduce the need for non-invasive tests in chest pain. However, since this PTP model is derived from data of a single medical center, multicenter verification is required to use it as a PTP recommended by the major American societies and the ESC.<br /><br />Copyright © 2023.

<div><h4>Mapping the characteristics, methodological quality and standards of reporting of network meta-analyses on antithrombotic therapies: An overview.</h4><i>de Sousa PG, Mainka FF, Tonin FS, Pontarolo R</i><br /><b>Background</b><br />Although a large number of network meta-analyses (NMAs) in the field of cardiology are available, little is known about their methodological quality. We aimed to map the characteristics and critically appraised the standards of conduct and evidence reporting of NMAs assessing antithrombotic therapies for the treatment or prophylaxis of heart diseases and cardiac surgical procedures.<br /><b>Methods</b><br />We systematically searched PubMed and Scopus to identify NMAs comparing the clinical effects of antithrombotic therapies. Overall characteristics of the NMAs were extracted and their reporting quality and methodological quality were evaluated using the PRISMA-NMA checklist and AMSTAR-2, respectively.<br /><b>Results</b><br />We found 86 NMAs published between 2007 and 2022. Comparisons among direct-acting oral anticoagulants were available in 61 (71%) NMAs. Although around 75% of NMAs stated that they followed international guidelines for conduct and reporting, only one third provided a protocol/register. Complete search strategies and publication bias assessment were lacking in around 53% and 59% of studies, respectively. Most NMAs (n = 77, 90%) provided supplemental material; however, only 5 (6%) made the complete raw data available. Network diagrams were depicted in most studies (n = 67, 78%), yet network geometry was described in only 11 (12.8%) of them. Mean adherence to the PRISMA-NMA checklist was 65.1 ± 16.5%. AMSTAR-2 assessment showed 88% of the NMAs had critically low methodological quality.<br /><b>Conclusion</b><br />Although there is a wide diffusion of NMA-type studies on antithrombotics for heart diseases, their methodological and reporting quality remains suboptimal. This may reflect fragile clinical practices due to misleading conclusions from critically low-quality NMAs.<br /><br />Copyright © 2023.

<div><h4>The prognostic value of cardiopulmonary exercise testing and HFA-PEFF in patients with unexplained dyspnea and preserved left ventricular ejection fraction.</h4><i>Lee K, Jung JH, Kwon W, Ohn C, ... Park MW, Cho JS</i><br /><b>Background</b><br />HFA-PEFF and cardiopulmonary exercise testing (CPET) are comprehensive diagnostic tools for heart failure with preserved ejection fraction (HFpEF). We aimed to investigate the incremental prognostic value of CPET for the HFA-PEFF score among patients with unexplained dyspnea with preserved ejection fraction (EF).<br /><b>Methods</b><br />Consecutive patients with dyspnea and preserved EF (n = 292) were enrolled between August 2019 and July 2021. All patients underwent CPET and comprehensive echocardiography, including two-dimensional speckle tracking echocardiography in the left ventricle, left atrium and right ventricle. The primary outcome was defined as a composite cardiovascular event including cardiovascular-related mortality, acute recurrent heart failure hospitalization, urgent repeat revascularization/myocardial infarction or any hospitalization due to cardiovascular events.<br /><b>Results</b><br />The mean age was 58 ± 14.5 years, and 166 (56.8%) participants were male. The study population was divided into three groups based on the HFA-PEFF score: < 2 (n = 81), 2-4 (n = 159), and ≥ 5 (n = 52).

Abstract
<div><h4>Mortality after catheter ablation of structural heart disease related ventricular tachycardia.</h4><i>Bennett RG, Garikapati K, Campbell TG, Kotake Y, ... Wong MS, Kumar S</i><br /><b>Background</b><br />There is a paucity of data describing mortality after catheter ablation of ventricular tachycardia (VT).<br /><b>Objectives</b><br />We describe the causes and predictors of cardiac transplant and/or mortality following catheter ablation of structural heart disease (SHD) related VT.<br /><b>Methods</b><br />Over 10-years, 175 SHD patients underwent VT ablation. Clinical characteristics, and outcomes, were compared between patients undergoing transplant and/or dying and those surviving.<br /><b>Results</b><br />During 2.8 (IQR 1.9-5.0) years follow-up, 37/175 (21%) patients underwent transplant and/or died following VT ablation. Prior to ablation, these patients were older (70.3 ± 11.1 vs. 62.1 ± 13.9 years, P = 0.001), had lower left ventricular ejection fraction ([LVEF] 30 ± 12% vs. 44 ± 14%, P < 0.001), and were more likely to have failed amiodarone (57% vs. 39%, P = 0.050), compared to those that survived. Predictors of transplant and/or mortality included LVEF≤35% (HR 4.71 [95% CI 2.18-10.18], P < 0.001), age ≥ 65 years (HR 2.18 [95% CI 1.01-4.73], P = 0.047), renal impairment (HR 3.73 [95% CI 1.80-7.74], P < 0.001), amiodarone failure (HR 2.67 [95% CI 1.27-5.63], P = 0.010) and malignancy (HR 3.09 [95% CI 1.03-9.26], P = 0.043). Ventricular arrhythmia free survival at 6-months was lower in the transplant and/or deceased, compared to non-deceased group (62% vs. 78%, P = 0.010), but was not independently associated with transplant and/or mortality. The risk score, MORTALITIES-VA, accurately predicted transplant and/or mortality (AUC: 0.872 [95% CI 0.810-0.934]).<br /><b>Conclusions</b><br />Cardiac transplant and/or mortality after VT ablation occurred in 21% of patients. Independent predictors included LVEF≤35%, age ≥ 65 years, renal impairment, malignancy, and amiodarone failure. The MORTALITIES-VA score may identify patients at high-risk of transplant and/or dying after VT ablation.<br /><br />Copyright © 2023.

<div><h4>Neutrophil-lymphocyte ratio and clinical outcomes in 19,697 patients with atrial fibrillation: Analyses from ENGAGE AF- TIMI 48 trial.</h4><i>Fagundes A, Ruff CT, Morrow DA, Murphy SA, ... Braunwald E, Giugliano RP</i><br /><b>Background</b><br />The neutrophil-to-lymphocyte ratio (NLR) is the ratio between neutrophil and lymphocyte counts measured in peripheral blood is easily calculable based on a routine blood test available worldwide and may reflect systemic inflammation. However, the relationship between NLR and clinical outcomes in atrial fibrillation (AF) patients is not well-described.<br /><b>Methods</b><br />We calculated NLR at baseline in ENGAGE AF-TIMI 48, a randomized trial comparing edoxaban versus warfarin in patients with AF followed for 2.8 years (median). The association of baseline NLR with major bleeding events, major adverse cardiac events (MACE), cardiovascular death, stroke/systemic embolism, and all-cause mortality were calculated.<br /><b>Results</b><br />The median baseline NLR in 19,697 patients was 2.53 (interquartile range 1.89-3.41). NLR was associated with major bleeding events (HR 1.60; 95% CI 1.41-1.80), stroke/systemic embolism (HR 1.25; 95% CI, 1.09-1.44), MI (HR 1.73; 95% CI 1.41-2.12), MACE (HR 1.70; 95% CI 1.56-1.84), CV (HR 1.93; 95% CI 1.74-2.13) and all-cause mortality (HR 2.00; 95% CI 1.83-2.18). The relationships between NLR and outcomes remained significant after adjustment for risk factors. Edoxaban consistently reduced major bleeding. MACE, and CV death across NLR groups vs. warfarin.<br /><b>Conclusions</b><br />NLR represents a widely available, simple, arithmetic calculation that could be immediately and automatically reported during a white blood cell differential measurement to identify patients with AF at increased risk of bleeding, CV events, and mortality.<br /><br />Copyright © 2023.

Leite-Moreira A, Ferreira JP</i><br /><b>Background</b><br />Heart failure (HF) is associated with poor health status, and high morbi-mortality. However, it is not well established how health status changes correlate with treatment effects on clinical outcomes. Our aim was to study the association between treatment-induced changes in health-status, assessed by Kansas City Cardiomyopathy Questionnaire 23 (KCCQ-23) and clinical outcomes in chronic HF.<br /><b>Methods</b><br />Systematic search of phase III-IV pharmacological RCTs in chronic HF that assessed KCCQ-23 changes and clinical outcomes throughout follow-up. We studied the association between treatment induced changes in KCCQ-23 and treatment effects on clinical outcomes (HF hospitalization or cardiovascular death, HF hospitalization, cardiovascular death, and all-cause death) using weighted random-effects meta-regression.<br /><b>Results</b><br />Sixteen trials were included, enrolling a total of 65,664 participants. Treatment induced KCCQ-23 changes were moderately correlated with treatment effects on the combined outcome of HF hospitalization or cardiovascular mortality (regression coefficient (RC) = -0.047, 95%CI: -0.085 to -0.009; R<sup>2</sup> = 49%), a correlation that was mainly driven by HF hospitalization (RC = -0.076, 95%CI: -0.124 to -0.029; R<sup>2</sup> = 56%). Correlations of treatment induced KCCQ-23 changes with cardiovascular death (RC = -0.029, 95%CI: -0.073 to 0.015; R<sup>2</sup> = 10%) and all-cause death (RC = -0.019, 95%CI: -0.057 to 0.019; R<sup>2</sup> = 0%) were weak and non-significant.<br /><b>Conclusions</b><br />Treatment-induced changes in KCCQ-23 were moderately correlated with treatment-effects on HF hospitalizations but were not correlated with the effects on cardiovascular and all-cause mortality. Treatment-induced changes in patient-centered outcomes (i.e., KCCQ-23) may reflect non-fatal symptomatic changes in the clinical course of HF leading to hospitalization.<br /><br />Copyright © 2023.

<div><h4>Using machine learning to predict cardiovascular risk using self-reported questionnaires: Findings from the 45 and up study.</h4><i>Wang H, Tucker WJ, Jonnagaddala J, Schutte AE, ... Wong RK, Ong KL</i><br /><b>Background</b><br />Machine learning has been shown to outperform traditional statistical methods for risk prediction model development. We aimed to develop machine learning-based risk prediction models for cardiovascular mortality and hospitalisation for ischemic heart disease (IHD) using self-reported questionnaire data.<br /><b>Methods</b><br />The 45 and Up Study was a retrospective population-based study in New South Wales, Australia (2005-2009). Self-reported healthcare survey data on 187,268 participants without a history of cardiovascular disease was linked to hospitalisation and mortality data. We compared different machine learning algorithms, including traditional classification methods (support vector machine (SVM), neural network, random forest and logistic regression) and survival methods (fast survival SVM, Cox regression and random survival forest).<br /><b>Results</b><br />A total of 3687 participants experienced cardiovascular mortality and 12,841 participants had IHD-related hospitalisation over a median follow-up of 10.4 years and 11.6 years respectively. The best model for cardiovascular mortality was a Cox survival regression with L1 penalty at a re-sampled case/non-case ratio of 0.3 achieved by under-sampling of the non-cases. This model had the Uno\'s and Harrel\'s concordance indexes of 0.898 and 0.900 respectively. The best model for IHD hospitalisation was a Cox survival regression with L1 penalty at a re-sampled case/non-case ratio of 1.0 with Uno\'s and Harrel\'s concordance indexes of 0.711 and 0.718 respectively.<br /><b>Conclusion</b><br />Machine learning-based risk prediction models developed using self-reported questionnaire data had good prediction performance. These models may have the potential to be used in initial screening tests to identify high-risk individuals before undergoing costly investigation.<br /><br />Copyright © 2023 The Author.

<div><h4>Precipitating factors in patients with spontaneous coronary artery dissection: Clinical, laboratoristic and prognostic implications.</h4><i>Gurgoglione FL, Rizzello D, Giacalone R, Ferretti M, ... Niccoli G, Solinas E</i><br /><b>Background</b><br />Spontaneous coronary artery dissection (SCAD) often presents with acute coronary syndrome and underlying pathophysiology involves the interplay between predisposing factors and precipitating stressors, such as emotional and physical triggers. In our study we sought to compare clinical, angiographic and prognostic features in a cohort of patients with SCAD according to the presence and type of precipitating stressors.<br /><b>Methods</b><br />Consecutive patients with angiographic evidence of SCAD were divided into three groups: patients with emotional stressors, patients with physical stressors and those without any stressor. Clinical, laboratoristic and angiographic features were collected for each patient. The incidence of major adverse cardiovascular events, recurrent SCAD and recurrent angina was assessed at follow-up.<br /><b>Results</b><br />Among the total population (64 subjects), 41 [64.0%] patients presented with precipitating stressors, including emotional triggers (31 [48.4%] subjects) and physical efforts (10 [15.6%] subjects). As compared with the other groups, patients with emotional triggers were more frequently female (p = 0.009), had a lower prevalence of hypertension (p = 0.039] and dyslipidemia (p = 0.039), were more likely to suffer from chronic stress (p = 0.022) and presented with higher levels of C-reactive protein (p = 0.037) and circulating eosinophils cells (p = 0.012). At a median follow-up of 21 [7; 44] months, patients with emotional stressors experienced higher prevalence of recurrent angina (p = 0.025), as compared to the other groups.<br /><b>Conclusions</b><br />Our study shows that emotional stressors leading to SCAD may identify a SCAD subtype with specific features and a trend towards a worse clinical outcome.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

Secondary aim was to identify the predictors for low cardiac output syndrome (LCOS).<br /><b>Methods</b><br />Prospectively collected data of 207 consecutive patients with LVEF ≤30% undergoing elective isolated CABG with CPB from 01/2009 to 12/2019, 136 with and 71 patients without IABP, were retrieved retrospectively. Patients with prophylactic IABP were matched 1:1 with patients without IABP by a propensity score matching. Stepwise logistic regression was conducted to identify predictors of postoperative LCOS in the propensity-matched cohort. P value ≤0.05 was considered significant.<br /><b>Results</b><br />Reduced postoperative LCOS (9.9% vs. 26.8%, P = 0.017) was observed in patients receiving prophylactic IABP. Stepwise logistic regression identified preoperative IABP as preventive factor for postoperative LCOS [Odds Ratio (OR) 0.19,95% Confidence Interval (CI), 0.06-0.55, P = 0.004]. The need of vasoactive and inotropic support was lower in patients with prophylactic IABP at 24, 48 and 72 h after surgery (12.3 [8.2-18.6] vs. 22.2 [14.4-28.8], P < 0.001, 7.7 [3.3-12.3] vs.16.3 [8.9-27.8], P < 0.001 and 2.4 [0-7] vs. 11.5 [3.1-26], P < 0.001, respectively). The patients in both groups did not differ in terms of in-hospital mortality (7.0% vs. 9.9%, P = 0.763). There were no major IABP-related complications.<br /><b>Conclusions</b><br />Elective patients with left ventricular ejection fraction ≤30% undergoing CABG with CPB and prophylactic IABP insertion had less low cardiac output syndrome and similar in-hospital mortality.<br /><br />Copyright © 2023.

<div><h4>Attenuation of ST-segment elevation by ischemic preconditioning: Reflection of cardioprotection in Göttingen but not in Ossabaw minipigs.</h4><i>Lieder HR, Adam V, Skyschally A, Sturek M, Kleinbongard P, Heusch G</i><br /><b>Background</b><br />Ischemic preconditioning (IPC; brief cycles of coronary occlusion/ reperfusion) reduces myocardial infarct size. The ST-segment elevation during coronary occlusion is progressively attenuated with increasing number of IPC cycles. Progressive attenuation of ST-segment elevation is considered a result of sarcolemmal K<sub>ATP</sub> channel activation and has been considered to reflect and predict IPC\'s cardioprotection. We have recently demonstrated that IPC failed to reduce infarct size in minipigs of a particular strain (Ossabaw), which had a genetic predisposition to develop, but not yet established a metabolic syndrome. To determine whether or not Ossabaw minipigs nevertheless had attenuated ST-segment elevation over repetitive IPC cycles, we compared Göttingen vs. Ossabaw minipigs in which IPC reduces infarct size.<br /><b>Methods and results</b><br />We analyzed surface chest electrocardiographic (ECG) recordings of anesthetized open-chest contemporary Göttingen (n = 43) and Ossabaw minipigs (n = 53). Both minipig strains were subjected to 60 min coronary occlusion and 180 min reperfusion without or with IPC (3 × 5 min/ 10 min coronary occlusion/ reperfusion). ST-segment elevations during the repetitive coronary occlusions were analyzed. In both minipig strains, IPC attenuated ST-segment elevation with increasing number of coronary occlusions. IPC reduced infarct size in Göttingen minipigs (45 ± 10% without vs. 25 ± 13% of area at risk with IPC), whereas such cardioprotection was absent in Ossabaw minipigs (54 ± 11% vs. 50 ± 11%).<br /><b>Conclusion</b><br />Apparently, the block of signal transduction of IPC in Ossabaw minipigs occurs distal to the sarcolemma, where K<sub>ATP</sub> channel activation still attenuates ST-segment elevation as it does in Göttingen minipigs.<br /><br />Copyright © 2023.

<div><h4>Identifying distinct clinical clusters in heart failure with mildly reduced ejection fraction.</h4><i>Meijs C, Brugts JJ, Lund LH, Linssen GCM, ... Savarese G, Uijl A</i><br /><b>Introduction</b><br />Heart failure (HF) is a heterogeneous syndrome, and the specific sub-category HF with mildly reduced ejection fraction (EF) range (HFmrEF; 41-49% EF) is only recently recognized as a distinct entity. Cluster analysis can characterize heterogeneous patient populations and could serve as a stratification tool in clinical trials and for prognostication. The aim of this study was to identify clusters in HFmrEF and compare cluster prognosis.<br /><b>Methods and results</b><br />Latent class analysis to cluster HFmrEF patients based on their characteristics was performed in the Swedish HF registry (n = 7316). Identified clusters were validated in a Dutch cross-sectional HF registry-based dataset CHECK-HF (n = 1536). In Sweden, mortality and hospitalisation across the clusters were compared using a Cox proportional hazard model, with a Fine-Gray sub-distribution for competing risks and adjustment for age and sex. Six clusters were discovered with the following prevalence and hazard ratio with 95% confidence intervals (HR [95%CI]) vs. cluster 1: 1) low-comorbidity (17%, reference), 2) ischaemic-male (13%, HR 0.9 [95% CI 0.7-1.1]), 3) atrial fibrillation (20%, HR 1.5 [95% CI 1.2-1.9]), 4) device/wide QRS (9%, HR 2.7 [95% CI 2.2-3.4]), 5) metabolic (19%, HR 3.1 [95% CI 2.5-3.7]) and 6) cardio-renal phenotype (22%, HR 2.8 [95% CI 2.2-3.6]). The cluster model was robust between both datasets.<br /><b>Conclusion</b><br />We found robust clusters with potential clinical meaning and differences in mortality and hospitalisation. Our clustering model could be valuable as a clinical differentiation support and prognostic tool in clinical trial design.<br /><br />Copyright © 2023.

<div><h4>Optimal outcomes from cardiac rehabilitation are associated with longer-term follow-up and risk factor status at 12 months: An observational registry-based study.</h4><i>Tang LH, Doherty P, Skou ST, Harrison A</i><br /><b>Aim</b><br />The purpose of Cardiac Rehabilitation (CR) is to promote and reduce risk factors in the short and long term, however, the latter has, to date, been poorly evaluated. We explored characteristics associated with provision and outcomes of a long-term assessment in CR.<br /><b>Method</b><br />Data from the UK National Audit of CR between April 2015 and March 2020 was used. Programmes were selected if they had an established mechanism and routine methodology to collect the 12-month assessments. Risk factors pre and post phase II CR and at the 12-month assessment were explored; BMI ≤30, ≥150 min of physical activity per week, hospital anxiety and depression scale (HADS) scores <8. The data came from 32 programmes, 24,644 patients with coronary heart disease. Patients being in at least one optimal risk factor stage throughout phase II CR (OR = 1.43 95% CI 1.28 to 1.59) or successfully reaching an optimal stage during phase II CR (OR = 1.61 95% CI 1.44 to 1.80) had an increased likelihood of being assessed at 12 months compared to those who did not. Patients being in the optimal stage upon completion of phase II CR had an increased likelihood of still being in the optimal stage at 12 months. Most prominent was BMI; (OR = 14.6 (95% CI 11.1 to 19.2) for patients reaching an optimal stage throughout phase II CR.<br /><b>Conclusion</b><br />Being in an optimal stage upon routine CR completion could be an overlooked predictor in the provision of a long-term CR service and prediction of longer-term risk factor status.<br /><br />Copyright © 2023.

<div><h4>Emerging role of PET/MR in the diagnosis and characterization of cardiotoxicity?</h4><i>Schindler TH, Sivapackiam J, Sharma V</i><br /><AbstractText>In cardiotoxicity, PET/MR affords an accurate evaluation of cardiovascular morphology, function, and also multi-parametric tissue characterization. A composite of several cardiac imaging parameters provided by the PET/MR scanner is likely to outperform a single parameter or imaging modality in the assessment and prediction of the severity and progression of cardiotoxicity but needing clinical investigations. Of particular interest, a heterogeneity map of single PET and CMR parameters could be perfectly correlated with the PET/MR scanner likely emerging as a promising marker of cardiotoxicity to monitor treatment response. While such functional and structural multiparametric imaging approach with cardiac PET/MR in the assessment and characterization of cardiotoxicity holds much promise, its validity and value in cancer patients treated with chemotherapy and/or radiation still needs to be assessed. The multi-parametric imaging approach with PET/MR, however, is likely to set new standards to develop predictive constellations of parameters for the severity and potential progression of cardiotoxicity that should afford timely and individualized treatment intervention to ascertain myocardial recovery and improved clinical outcome in these high-risk patients.</AbstractText><br /><br />Copyright © 2023.

Lip GYH, Pastori D</i><br /><b>Background</b><br />New onset atrial fibrillation (NOAF) is associated with worse clinical outcomes after acute coronary syndrome (ACS). Identification of ACS patients at risk of NOAF remains challenging. To test the value of the simple C<sub>2</sub>HEST score for predicting NOAF in patients with ACS.<br /><b>Methods</b><br />We studied patients from the prospective ongoing multicenter REALE-ACS registry of patients with ACS. NOAF was the primary endpoint of the study. The C<sub>2</sub>HEST score was calculated as coronary artery disease or chronic obstructive pulmonary disease (1 point each), hypertension (1 point), elderly (age ≥ 75 years, 2 points), systolic heart failure (2 points), thyroid disease (1 point). We also tested the mC<sub>2</sub>HEST score.<br /><b>Results</b><br />We enrolled 555 patients (mean age 65.6 ± 13.3 years; 22.9% women), of which 45 (8.1%) developed NOAF. Patients with NOAF were older (p < 0.001) and had more prevalent hypertension (p = 0.012), chronic obstructive pulmonary disease (p < 0.001) and hyperthyroidism (p = 0.018). Patients with NOAF were more frequently admitted with STEMI (p < 0.001), cardiogenic shock (p = 0.008), Killip class ≥2 (p < 0.001) and had higher mean GRACE score (p < 0.001). Patients with NOAF had a higher C<sub>2</sub>HEST score compared with those without (4.2 ± 1.7 vs 3.0 ± 1.5, p < 0.001). A C<sub>2</sub>HEST score > 3 was associated with NOAF occurrence (odds ratio 4.33, 95% confidence interval 2.19-8.59, p < 0.001). ROC curve analysis showed good accuracy of the C<sub>2</sub>HEST score (AUC 0.71, 95%CI 0.67-0.74) and mC<sub>2</sub>HEST score (AUC 0.69, 95%CI 065-0.73) in predicting NOAF.<br /><b>Conclusions</b><br />The simple C<sub>2</sub>HEST score may be a useful tool to identify patients at higher risk of developing NOAF after presentation with ACS.<br /><br />Copyright © 2023.

<div><h4>Discrepancy between invasive and echocardiographic transvalvular gradient after TAVI: Insights from the LAPLACE-TAVI registry.</h4><i>Yamazaki C, Higuchi R, Saji M, Takamisawa I, ... Takanashi S, Isobe M</i><br /><b>Background</b><br />Echocardiography-based transvalvular mean pressure gradient (ECHO-mPG) used to assess the forward valve function and structural valve deterioration could overestimate the true pressure gradient. This study evaluated the discrepancy between invasive and ECHO-mPG after transcatheter aortic valve implantation (TAVI) with respective valve type and size, its impact on a device success criterion, and predictors of a pressure discrepancy.<br /><b>Methods</b><br />We analyzed 645 patients registered in a multicenter TAVI registry (balloon-expandable valve [BEV]: 500; self-expandable valve [SEV]: 145). The invasive transvalvular mPG was measured after valve implantation using two Pigtail catheters (CATH-mPG), while the ECHO-mPG was measured within 48 h after TAVI. Pressure recovery (PR) was calculated using the following formula: ECHO-mPG × effective orifice area (EOA)/ascending aortic area (AoA) × (1 - EOA/AoA).<br /><b>Results</b><br />ECHO-mPG was weakly correlated with (r = 0.29, p < 0.0001), and consistently overestimated CATH-mPG in both BEV and SEV, and respective valve sizes. The magnitude of the discrepancy was larger for BEV than SEV (p < 0.001) and smaller valves (p < 0.001). After the correction of PR using the above formula, the pressure discrepancy remained for BEV (p < 0.001) but not SEV (p = 0.10). The proportion of patients with an ECHO-mPG > 20 mmHg decreased from 7.0% to 1.6% after correction (p < 0.0001).

Abstract
<div><h4>Is spontaneous coronary artery dissection (SCAD) related to local anatomy and hemodynamics? An exploratory study.</h4><i>Candreva A, Rizzini ML, Schweiger V, Gallo D, ... Morbiducci U, Templin C</i><br /><b>Aims</b><br />Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of myocardial infarction with unclear pathophysiology. The aim of the study was to test if vascular segments site of SCAD present distinctive local anatomy and hemodynamic profiles.<br /><b>Methods</b><br />Coronary arteries with spontaneously healed SCAD (confirmed by follow-up angiography) underwent three-dimensional reconstruction, morphometric analysis with definition of vessel local curvature and torsion, and computational fluid dynamics (CFD) simulations with derivation of time-averaged wall shear stress (TAWSS) and topological shear variation index (TSVI). The (reconstructed) healed proximal SCAD segment was visually inspected for co-localization with curvature, torsion, and CFD-derived quantities hot spots.<br /><b>Results</b><br />Thirteen vessels with healed SCAD underwent the morpho-functional analysis. Median time between baseline and follow-up coronary angiograms was 57 (interquartile range [IQR] 45-95) days. In seven cases (53.9%), SCAD was classified as type 2b and occurred in the left anterior descending artery or near a bifurcation. In all cases (100%), at least one hot spot co-localized within the healed proximal SCAD segment, in 9 cases (69.2%) ≥3 hot spots were identified. Healed SCAD in proximity of a coronary bifurcation presented lower TAWSS peak values (6.65 [IQR 6.20-13.2] vs. 3.81 [2.53-5.17] Pa, p = 0.008) and hosted less frequently TSVI hot spots (100% vs. 57.1%, p = 0.034).<br /><b>Conclusion</b><br />Vascular segments of healed SCAD were characterized by high curvature/torsion and WSS profiles reflecting increased local flow disturbances. Hence, a pathophysiological role of the interaction between vessel anatomy and shear forces in SCAD is hypothesized.<br /><br />Copyright © 2023 The Author. Published by Elsevier B.V.

<div><h4>European practice patterns for antiplatelet management in NSTE-ACS patients: Results from the REal-world ADoption survey focus on acute antiPlatelet treatment (READAPT) survey.</h4><i>Angiolillo DJ, Erlinge D, Ferreiro JL, Gale CP, ... Musumeci G, Collet JP</i><br /><b>Background</b><br />The 2020 European Society of Cardiology (ESC) guidelines for the diagnosis and management of patients with non-ST elevation-acute coronary syndrome (NSTE-ACS) recommend early invasive coronary angiography in high-risk patients and no routine pre-treatment with oral P2Y12 receptor inhibitor in NSTE-ACS patients prior to defining coronary anatomy.<br /><b>Objective</b><br />To assess the implementation of this recommendation in the real-life setting.<br /><b>Methods</b><br />A web-survey in 17 European countries collected physician profiles and their perceptions of the diagnosis, medical and invasive management of NSTE-ACS patients at their hospital. A sample size of at least 1100 responders permitted the estimation of proportions with a precision of at least ±3.0%.<br /><b>Results</b><br />Among the 3024 targeted participants, 1154 provided valid feedback defined as a 50% response rate of answers to the survey questions. Overall, >60% of the participants declared full implementation of the guidelines at their institution. The time delay from admission to coronary angiography and PCI was reported to be <24 h in over 75% of the hospitals while pre-treatment was intended in >50% of NSTE-ACS patients. Ad-hoc percutaneous coronary intervention (PCI) was performed in >70% of the cases while intravenous platelet inhibition was rarely used (<10%). Between countries differences in practice patterns for antiplatelet management for NSTE-ACS were observed, suggesting heterogeneous implementation of the guidelines.<br /><b>Conclusions</b><br />This survey indicates that the implementation of 2020 NSTE-ACS guidelines on early invasive management and pre-treatment is heterogeneous, potentially due by local logistical constraints.<br /><br />Copyright © 2023.

<div><h4>Nomograms referenced by cardiac magnetic resonance in the prediction of cardiac injuries in patients with ST-elevation myocardial infarction.</h4><i>Zhao CX, Wei L, Dong JX, He J, ... Ge H, Pu J</i><br /><b>Background</b><br />Evaluation of cardiac injuries is essential in patients with ST-elevation myocardial infarction (STEMI). Cardiac magnetic resonance (CMR) has become the gold standard for quantifying cardiac injuries; however, its routine application is limited. A nomogram is a useful tool for prognostic prediction based on the comprehensive utilization of clinical data. We presumed that the nomogram models established using CMR as a reference could precisely predict cardiac injuries.<br /><b>Methods</b><br />This analysis included 584 patients with acute STEMI from a CMR registry study for STEMI (NCT03768453). The patients were divided into training (n = 408) and testing (n = 176) datasets. The least absolute shrinkage method, selection operator method, and multivariable logistic regression were used to construct nomograms for predicting left ventricular ejection fraction (LVEF) ≤40%, infarction size (IS) ≥ 20% on the LV mass, and microvascular dysfunction.<br /><b>Results</b><br />The nomogram for predicting LVEF≤40%, IS≥20%, and microvascular dysfunction comprised 14, 10, and 15 predictors, respectively. With the nomograms, the individual risk probability of developing specific outcomes could be calculated, and the weight of each risk factor was demonstrated. The C-index of the nomograms in the training dataset were 0.901, 0.831, and 0.814, respectively, and were comparable in the testing set, showing good nomogram discrimination and calibration. The decision curve analysis demonstrated good clinical effectiveness. Online calculators were also constructed.<br /><b>Conclusions</b><br />With the CMR results as the reference standard, the established nomograms demonstrated good effectiveness in predicting cardiac injuries after STEMI and could provide physicians with a new option for individual risk stratification.<br /><br />Copyright © 2023.

<div><h4>Thromboembolic risk scores in patients with non-obstructive coronary architecture with and without coronary slow flow: A case-control study.</h4><i>Genç Ö, Yildirim A, Alici G, Harbalioğlu H, ... Şeker T, Güler A</i><br /><b>Aim</b><br />Coronary slow flow phenomenon (CSFP) detected on coronary angiography (CA) has been related to poor prognosis. We sought to examine the relationship between thromboembolic risk scores, routinely used in cardiology practice, and CSFP.<br /><b>Methods</b><br />This single-center, retrospective, case-control study comprised 505 individuals suffering from angina and had verified ischemia between January 2021 and January 2022. Demographic and laboratory parameters were obtained from the hospital database. The following risk scores were calculated; CHA<sub>2</sub>DS<sub>2</sub>-VASc, M-CHA<sub>2</sub>DS<sub>2</sub>-VASc, CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS, R<sub>2</sub>-CHA<sub>2</sub>DS<sub>2</sub>-VASc, M-R<sub>2</sub>-CHA<sub>2</sub>DS<sub>2</sub>-VASc, ATRIA, M-ATRIA, M-ATRIA-HSV. The overall population was divided into two groups; coronary slow flow and coronary normal flow. Multivariable logistic regression was performed to compare risk scores between patients with and without CSFP. Pairwise comparisons were then undertaken to test performance in determining CSFP.<br /><b>Results</b><br />The mean age was 51.7 ± 10.7 years, of whom 63.2% were male. CSFP was detected in 222 patients. Those with CSFP had higher rates of male gender, diabetes, smoking, hyperlipidemia, and vascular disease. All scores were higher in CSFP patients. Multivariable logistic regression analysis found that CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score was the most powerful determinant of CSFP among all risk schemes (for each one-point increase in score OR = 1.90, p < 0.001; for score of 2-3 OR = 5.20, p < 0.001; for score of >4 OR = 13.89, p < 0.001). Also, the CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score provided the best discriminative performance, with a cut-off value of ≥2 in identifying CSFP (AUC = 0.759, p < 0.001).<br /><b>Conclusion</b><br />We showed that thromboembolic risk scores may be associated with CSFP in patients with non-obstructive coronary architecture who underwent CA. The CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score had the best discriminative ability.<br /><br />Copyright © 2023.

<div><h4>Predictors of arrhythmia during pregnancy in adults with congenital heart disease.</h4><i>Venkatesh P, Lin JP, Nguyen A, Rezkalla J, Moore JP</i><br /><b>Background</b><br />Risk prediction of arrhythmia during pregnancy in adult congenital heart disease (ACHD) patients is currently lacking, and the impact of preconception catheter ablation on future antepartum arrhythmia has not been studied.<br /><b>Methods</b><br />We conducted a single-center, retrospective cohort study of pregnancies in ACHD patients. Clinically significant arrhythmia events during pregnancy were described, predictors of arrhythmia were analyzed, and a risk score devised. The impact of preconception catheter ablation on antepartum arrhythmia was assessed.<br /><b>Results</b><br />The study included 172 pregnancies in 137 patients. Arrhythmia events occurred in 25 (15%) of pregnancies, with 64% of events occurring in the second trimester and sustained supraventricular tachycardia being the most common rhythm. Univariate predictors of arrhythmia were history of tachyarrhythmia (OR 20.33, 95% CI 6.95-59.47, p < 0.001, Fontan circulation (OR 11.90, 95% CI 2.60-53.70, p < 0.001), baseline physiologic class C/D (OR 3.72, 95% CI 1.54-9.01, p = 0.002) and history of multiple valve interventions (OR 3.10, 95% CI 1.20-8.20, p = 0.017). Three risk factors (excluding multiple valve interventions) were used to formulate a risk score, with a cutoff of ≥2 points predicting antepartum arrhythmia with sensitivity and specificity of 84%. While recurrence of the index arrhythmia was not observed following successful catheter ablation, preconception ablation did not impact odds of antepartum arrhythmia.<br /><b>Conclusions</b><br />We provide a novel risk stratification scheme for predicting antepartum arrhythmia in ACHD patients. The role of contemporary preconception catheter ablation in risk reduction needs further refinement with multicenter investigation.<br /><br />Copyright © 2023.

<div><h4>Changes in cardiac time intervals over a decade and the risk of incident heart failure: The Copenhagen City heart study.</h4><i>Alhakak AS, Olsen FJ, Skaarup KG, Lassen MCH, ... Møgelvang R, Biering-Sørensen T</i><br /><b>Background</b><br />The cardiac time intervals include the isovolumic contraction time (IVCT), the left ventricular ejection time (LVET), the isovolumic relaxation time (IVRT) and the combination of all the cardiac time intervals in the myocardial performance index (MPI) (defined as [(IVCT+IVRT)/LVET)]. Whether the cardiac time intervals change over time and which clinical factors that accelerate these changes is not well-established. Additionally, whether these changes are associated with subsequent heart failure (HF), remains unknown.<br /><b>Methods</b><br />We investigated participants from the general population (n = 1064) who had an echocardiographic examination including color tissue Doppler imaging performed in both the 4th and 5th Copenhagen City Heart Study. The examinations were performed 10.5 years apart.<br /><b>Results</b><br />The IVCT, LVET, IVRT and MPI increased significantly over time. None of the investigated clinical factors were associated with increase in IVCT. Systolic blood pressure (standardized β= - 0.09) and male sex (standardized β= - 0.08) were associated with an accelerated decrease in LVET. Age (standardized β=0.26), male sex (standardized β=0.06), diastolic blood pressure (standardized β=0.08), and smoking (standardized β=0.08) were associated with an increase in IVRT, while HbA1c (standardized β= - 0.06) was associated with a decrease in IVRT. Increasing IVRT over a decade was associated with an increased risk of subsequent HF in participants aged <65 years (per 10 ms increase: HR 1.33; 95%CI (1.02-1.72), p = 0.034).<br /><b>Conclusion</b><br />The cardiac time increased significantly over time.

<div><h4>EXpansion of stents after intravascular lithoTripsy versus conventional predilatation in CALCified coronary arteries.</h4><i>Oomens T, Vos NS, van der Schaaf RJ, Amoroso G, ... Slagboom T, Vink MA</i><br /><b>Background</b><br />Coronary artery calcification is a strong predictor for procedural failure and is independently associated with adverse events after percutaneous coronary intervention (PCI). An important contributor to the impaired outcome is the inability to achieve optimal results due to stent underexpansion or stent deformation/fracture. Intravascular lithotripsy (IVL) has emerged as an alternative technique to change the integrity of calcified plaques.<br /><b>Aims</b><br />Our aim was to investigate if pre-treatment with IVL in severely calcified lesions increases stent expansion, assessed by optical coherence tomography (OCT), when compared to predilatation with conventional and/or specialty balloon strategy.<br /><b>Methods</b><br />EXIT-CALC was a prospective, single-centre, randomised controlled study. Patients with an indication for PCI and severe calcification of the target lesion were allocated to predilatation with conventional angioplasty balloons or pre-treatment with IVL, followed by drug-eluting stenting and mandatory postdilatation. Primary endpoint was stent expansion assessed by OCT. Secondary endpoints were the occurrence of peri-procedural events and major adverse cardiac events (MACE) in hospital and during follow-up.<br /><b>Results</b><br />A total of 40 patients were included. The minimal stent expansion in the IVL-group (n = 19) was 83.9 ± 10.3% and 82.2 ± 11.5% in the conventional group (n = 21) (p = 0.630). Minimal stent area was 6.6 ± 1.5 mm<sup>2</sup> and 6.2 ± 1.8 mm<sup>2</sup>, respectively (p = 0.406). No peri-procedural, in-hospital and 30-day follow-up MACE were reported.<br /><b>Conclusions</b><br />In severely calcified coronary lesions we found no significant difference in stent expansion measured by OCT when comparing IVL, as plaque modification, with conventional and/or specialty angioplasty balloons.<br /><br />Copyright © 2023.

<div><h4>Association between trajectories in cardiac damage and clinical outcomes after transcatheter aortic valve replacement.</h4><i>Zhou Y, Lin X, Zhu Q, Li H, ... Liu X, Wang J</i><br /><b>Background</b><br />There is little evidence of evolution in cardiac damage after transcatheter aortic valve replacement (TAVR) in aortic stenosis (AS) patients. Less is known about the prognostic value and potential utility of different cardiac damage trajectories following TAVR.<br /><b>Objectives</b><br />This study aims to investigate the cardiac damage trajectories following TAVR and explore their association with subsequent clinical outcomes.<br /><b>Methods</b><br />AS patients undergoing TAVR were enrolled and classified into five cardiac damage stages (0-4) based on the echocardiographic staging classification retrospectively. They were further grouped into early stage (stage 0-2) and advanced stage (stage 3-4). The cardiac damage trajectories in TAVR recipients were evaluated according to their trend between baseline and 30 days after TAVR.<br /><b>Results</b><br />A total of 644 TAVR recipients were enrolled, with four distinct trajectories identified. Compared to patients with early-early trajectory, patients with early-advanced trajectory were at 30-fold risk of all-cause death (HR 30.99, 95% CI 13.80-69.56; p < 0.001). In multivariable analyses, early-advanced trajectory was associated with higher 2-year all-cause death (HR 24.08, 95% CI 9.07-63.90; p < 0.001), cardiac death (HR 19.34, 95% CI 3.06-122.34; p < 0.05), and cardiac rehospitalization (HR 4.19, 95% CI 1.49-11.76; p < 0.05) after TAVR.<br /><b>Conclusions</b><br />This investigation provided insight into four cardiac damage trajectories in TAVR recipients and confirmed the prognostic value of distinct trajectories.

Genovese F, Nielsen-Kudsk JE</i><br /><b>Background</b><br />In chronic thromboembolic pulmonary hypertension (CTEPH), fibrotic remodeling of tissue and thrombi contributes to disease progression. Removal of the thromboembolic mass by pulmonary endarterectomy (PEA) improves hemodynamics and right ventricular function, but the roles of different collagens before as well as after PEA are not well understood.<br /><b>Methods</b><br />In this study, hemodynamics and 15 different biomarkers of collagen turnover and wound healing were evaluated in 40 CTEPH patients at diagnosis (baseline) and 6 and 18 months after PEA. Baseline biomarker levels were compared with a historical cohort of 40 healthy subjects.<br /><b>Results</b><br />Biomarkers of collagen turnover and wound healing were increased in CTEPH patients compared with healthy controls, including a 35-fold increase in the PRO-C4 marker of type IV collagen formation and a 55-fold increase in the C3M marker of type III collagen degradation. PEA reduced pulmonary pressures to almost normal levels 6 months after the procedure, with no further improvement at 18 months. There were no changes in any of the measured biomarkers after PEA.<br /><b>Conclusions</b><br />Biomarkers of collagen formation and degradation are increased in CTEPH suggesting a high collagen turnover.

<div><h4>Rhodiola wallichiana var.cholaensis protects against myocardial ischemia-reperfusion injury by attenuating oxidative stress-mediated apoptosis via enhancing Nrf2 signaling.</h4><i>Yan T, Li X, Wang X, Zhang Y, ... Jia Y, Xiao W</i><br /><AbstractText>The present study aimed to explore the cardioprotective effects of Rhodiola wallichiana var.cholaensis (RW) against hypoxia/reoxygenation (H/R)-induced H9c2 cell injury and ischemia/reperfusion (I/R)-induced myocardial injury. Following treatment with RW, H9c2 cells were subjected to 4 h of hypoxia/3 h of reoxygenation. MTT assay, LDH assay, and flow cytometry were employed to detect cell viability and changes of ROS and mitochondrial membrane potential. Moreover, after RW treatment, rats underwent 30 min of ischemia, followed by 120 min of reperfusion. Masson and TUNEL staining were performed to measure myocardial damage and apoptosis, respectively. The changes in the levels of proteins were detected by ELISA and western blot. The results showed that RW attenuated the H/R-induced increase in LDH release and loss of the mitochondrial membrane potential, as well as the apoptosis in H9c2 cells. Meanwhile, RW significantly reduces the ST-segment elevation and improves cardiomyocytes\' injury, inhibit the apoptosis induced by I/R in rats. Furthermore, RW could decrease the levels of MDA and increase the levels of SOD, T-AOC. GSH-Px and GSH both in vivo and in vitro. Besides, RW increased the expressions of Nrf2, HO-1, ARE and NQO1, and decreased the expressions of Keap1, activating the Nrf2 signaling pathway. Taken together, these results suggested that RW exerts cardioprotection on H/R injury in H9c2 cells and I/R injury in rats by attenuating oxidative stress-mediated apoptosis via enhancing Nrf2 signaling.</AbstractText><br /><br />Copyright © 2023.

Palamà Z, Sciarra L</i><br /><AbstractText>Three-dimensional electroanatomical mapping (EAM) has the potential to identify the pathological substrate underlying ventricular arrhythmias (VAs) in different clinical settings by detecting myocardial areas with abnormally low voltages, which reflect the presence of different cardiomyopathic substrates. In athletes, the added value of EAM may be to enhance the efficacy of third-level diagnostic tests and cardiac magnetic resonance (CMR) in detecting concealed arrhythmogenic cardiomyopathies. Additional benefits of EAM in the athlete include the potential impact on disease risk stratification and the consequent implications for eligibility to competitive sports. This opinion paper of the Italian Society of Sports Cardiology aims to guide general sports medicine physicians and cardiologists on the clinical decision when to eventually perform an EAM study in the athlete, highlighting strengths and weaknesses for each cardiovascular disease at risk of sudden cardiac death during sport. The importance of early (preclinical) diagnosis to prevent the negative effects of exercise on phenotypic expression, disease progression, and worsening of the arrhythmogenic substrate is also addressed.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Hypotension at heart failure discharge: Should it be a limiting factor for drug titration?</h4><i>Melendo-Viu M, Dobarro D, López ÁM, Domínguez LM, ... García E, Romo AÍ</i><br /><b>Background</b><br />Medical treatment in Heart Failure (HF) with reduced ejection fraction (HFrEF; LVEF ≤40%) has shifted towards quadruple therapy. Maximum tolerated dose is the goal, yet no hypotension\'s cut-off point has been specified. In this work, we analyze the impact of intensive drug titration in clinical events, focusing on low blood pressure (BP) patients at hospital discharge.<br /><b>Methods and results</b><br />Retrospective analysis of 713 patients with HFrEF discharged after an acute HF event (mean LVEF 30 ± 5%). Mean SBP was 112.4 ± 16.5 mmHg and 50.6% were discharged on triple therapy. We considered hypotension as a Systolic blood pressure (SBP) <100 mmHg (21.7% of patients, mean SBP was 112.4 ± 16.5 mmHg) and codified the intensity of drug therapy in 5 stages from untreated to very high therapy intensity. The impact of the intensity of treatment was analysed with a propensity score and increasing the intensity was associated in the whole cohort with a reduction of the composite outcome of all-cause mortality and HF readmission, (HR 0.69; CI95% 0.57-0.85, p < 0.001) and benefit in mortality was maintained for SBP < 100 mmHg (HR 0.42; CI95% 0.22-0.82; p = 0.011). Moreover, therapy intensity was clearly associated with lower risk of HF-hospitalization and death after the additional regression, considering SBP as a covariate, in the whole cohort (HR 0.70; CI95% 0.57-0.85; p < 0.001).<br /><b>Conclusions</b><br />In this retrospective cohort analysis, patients with HFrEF and an acute-HF admission, intensive drug dose titration was related to better outcomes, even in patients with low blood pressure at hospital discharge. Therefore, hypotension is not a contraindication for NHB uptitration.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Pheochromocytoma-induced cardiogenic shock: A multicentre analysis of clinical profiles, management and outcomes.</h4><i>De Angelis E, Bochaton T, Ammirati E, Tedeschi A, ... Ravera A, Hayek A</i><br /><b>Objective</b><br />There is still uncertainty about the management of patients with pheochromocytoma-induced cardiogenic shock (PICS). This study aims to investigate the clinical presentation, management, and outcome of patients with PICS.<br /><b>Methods</b><br />We collected, retrospectively, the data of 18 patients without previously known pheochromocytoma admitted to 8 European hospitals with a diagnosis of PICS.<br /><b>Results</b><br />Among the 18 patients with a median age of 50 years (Q1-Q3: 40-61), 50% were men. The main clinical features at presentation were pulmonary congestion (83%) and cyclic fluctuation of hypertension peaks and hypotension (72%). Echocardiography showed a median left ventricular ejection fraction (LVEF) of 25% (Q1-Q3: 15-33.5) with an atypical- Takotsubo (TTS) pattern in 50%. Inotropes/vasopressors were started in all patients and temporary mechanical circulatory support (t-MCS) was required in 11 (61%) patients. All patients underwent surgical removal of the pheochromocytoma; 4 patients (22%) were operated on while under t-MCS. Mean LVEF was estimated at 55% at discharge. Only one patient required heart transplantation (5.5%), and all patients were alive at a median follow-up of 679 days.<br /><b>Conclusions</b><br />PICS should be suspected in case of a CS with severe cyclic blood pressure fluctuation and rapid hemodynamic deterioration, associated with increased inflammatory markers or in case of TTS progressing to CS, particularly if an atypical TTS echocardiographic pattern is revealed. T-MCS should be considered in the most severe cases. The main challenge is to stabilize the patient, with medical therapy or with t-MCS, since it remains a reversible cause of CS with a low mortality rate.<br /><br />Copyright © 2023.

Abstract
<div><h4>Declining trends of premature mortality from ischemic heart disease and regional differences in Italy from 2011 to 2017.</h4><i>Zuin M, di Fusco SA, De Caterina R, Roncon L, ... Colivicchi F, Bilato C</i><br /><b>Aims</b><br />Data regarding the premature mortality (<65 years of age) due to ischemic heart disease (IHD) in Italy are scant. We sought to analyze the incidence of premature death due to IHD in Italy and its time trend between years 2011 and 2017.<br /><b>Methods and results</b><br />We used the free publicly available EUROSTAT death certificate database to examine premature age-adjusted IHD mortality rates (per 100.000) and relative average annual percentage change (AAPC) in Italy from 2011 to 2017 using ICD-codes I20-I25. Over the study period, the proportional IHD-related mortality rates decline from 8.09% to 7.1% in the entire population (p for trend 0.012), showing a significant reduction in women (from 4.06% to 3.40%, p for trend: 0.02) but not in men (from 10.3% to 9.3%, p for trend 0.062). The age-adjusted IHD mortality rate decreased with an AAPC of -4.1 per year [(95% CI, -5.1 to -3.0), p < 0.001], resulting more pronounced in women [AAPC: -4.4 per year (95% CI: -6.4 to -2.3,), p = 0.001)] than in men [AAPC: -3.7 per year (95% CI: -5.4 to -2.0, p = 0.003)]. Age-adjusted IHD premature death rates above the 90th percentile were distributed in Italian southern regions and islands of Italy while premature death rates below the 10th percentile were clustered in the western and northeastern regions of the country.<br /><b>Conclusions</b><br />In Italy, premature IHD-related mortality remains an important contributor to overall mortality. Age-adjusted mortality declined in the last decade, especially in the northern regions and among women. Moreover, a marked region-level variations were observed.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Influence of exertional oscillatory breathing and its temporal behavior in patients with heart failure and reduced ejection fraction.</h4><i>Magrì D, Palermo P, Salvioni E, Mapelli M, ... Sciomer S, Agostoni P</i><br /><b>Background</b><br />Exertional oscillatory breathing (EOV) represents an emerging prognostic marker in heart failure (HF) patients, however little is known about EOV meaning with respect to its disappearance/persistence during cardiopulmonary exercise test (CPET). The present single-center study evaluated EOV clinical and prognostic impact in a large cohort of reduced ejection fraction HF patients (HFrEF) and, contextually, if a specific EOV temporal behavior might be an addictive risk predictor.<br /><b>Methods and results</b><br />Data from 1.866 HFrEF patients on optimized medical therapy were analysed. The primary cardiovascular (CV) study end-point was cardiovascular death, heart transplantation or LV assistance device (LVAD) implantation at 5-years. For completeness a secondary end-point of total mortality at 5- years was also explored. EOV presence was identified in 251 patients (13%): 142 characterized by EOV early cessation (Group A) and 109 by EOV persistence during the whole CPET (Group B). The entire EOV Group showed worse clinical and functional status than NoEOV Group (n = 1.615) and, within the EOV Group, Group B was characterized by a more severe HF. At CV survival analysis, EOV patients showed a poorer outcome than the NoEOV Group (events 27.1% versus 13.1%, p < 0.001) both unpolished and after matching for main confounders. Instead, no significant differences were found between EOV Group A and B with respect to CV outcome. Conversely the analysis for total mortality failed to be significant.<br /><b>Conclusions</b><br />Our analysis, albeit retrospective, supports the inclusion of EOV into a CPET-centered clinical and prognostic evaluation of the HFrEF patients. EOV characterizes per se a more advanced HFrEF stage with an unfavorable CV outcome. However, the EOV persistence, albeit suggestive of a more severe HF, does not emerge as a further prognostic marker.<br /><br />Copyright © 2023.

<div><h4>Age and long-term outcomes of patients with venous thromboembolism: From the COMMAND VTE Registry.</h4><i>Takahashi K, Yamashita Y, Morimoto T, Tada T, ... Kimura T, COMMAND VTE Registry Investigators</i><br /><b>Background</b><br />There is still a scarcity of data on the relation between age and long-term clinical outcomes of patients with venous thromboembolism (VTE).<br /><b>Methods</b><br />The COMMAND VTE Registry was a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE in Japan between January 2010 and August 2014. We divided the entire cohort into 3 groups: patients aged <65 years (N = 1100, 36.7%), patients aged 65 ≤ and ≤ 80 years (N = 1314, 43.4%), and patients aged >80 years (N = 603, 19.9%).<br /><b>Results</b><br />Discontinuation of anticoagulation therapy during the follow-up period was most frequent in patients aged <65 years (44%, 38% and 33%, P < 0.001). The cumulative 5-year incidences were 12.7%, 9.8% and 7.4% for recurrent VTE, 10.8%, 12.2% and 14.9% for major bleeding, and 23.0%, 31.4%, and 38.6% for all-cause death. Adjusting for cofounders and taking into account the competing risk of all-cause death, the lower risk of patients aged >80 years, and those aged 65 ≤ and ≤ 80 years relative to those aged <65 years remained significant for recurrent VTE (65 ≤ age ≤ 80 years, HR: 0.71, 95%CI: 0.53-0.94, P = 0.02; age > 80 years, HR: 0.59, 95%CI: 0.39-0.89, P = 0.01), and the risk remained insignificant for major bleeding (65 ≤ age ≤ 80 years, HR: 1.00, 95%CI: 0.76-1.31, P = 0.98; age > 80 years, HR: 1.17, 95%CI: 0.83-1.65, P = 0.37).<br /><b>Conclusions</b><br />In the current real-world VTE registry, there was no significant difference in the risk of major bleeding depending on different age groups, while younger patients showed an excess risk for recurrent VTE compared with older patients.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Global, regional, and national time trends in mortality for stroke, 1990-2019: An age-period-cohort analysis for the global burden of disease 2019 study and implications for stroke prevention.</h4><i>Peng S, Liu X, Cao W, Liu Y, ... Tang J, Zhang Q</i><br /><b>Background</b><br />Despite the fact that stroke is the second leading cause of death globally, a comprehensive and comparable assessment of mortality, and epidemiologic trends has not been conducted for most regions.We estimated the global and regional burden of stroke from 1990 to 2019 using data from the 2019 Global Study of Diseases, Injuries, and Risk Factors.<br /><b>Methods</b><br />For the period between 1990 and 2019, we used an age-period-cohort model to calculate the annual percentage changes in mortality (net drifts), local drifts, and period and cohort relative risks (period/cohort effects). Meanwhile, to quantify the temporal trends in stroke age-standardised mortality rate (ASMR), Average annual percentage changes (AAPCs) were determined by sex, area. With the potential to uncover disparities and treatment gaps in stroke care, this approach enables the examination and differentiation of age, period, and cohort effects in mortality trends.<br /><b>Findings</b><br />Global stroke deaths in 2019 were 6,552,725 (95% UI 5,995,200 to 7,015,139). Between 1990 and 2019, the ASMR declined globally by 36.43% (95% UI -41.65 to -31.2), with decreases in all SDI quintiles. The net drift in stroke mortality from 1990 to 2019 varied from -2.83% per year (95% confidence interval [CI]:-3.39 to -2.77) in countries with a high Socio-demographic Index (SDI) to -1.21% per year (95% CI: -1.26 to -1.16) in countries with a low SDI. During the past 30 years, favorable mortality reductions were generally found in high-SDI countries (net drift = -3.1% [95% CI: -3.4 to -2.8] per year) and high-middle SDI countries (-2.8% [-3.0 to -2.6]). However, 31 of 204 countries had either increasing trends (net drifts≥0.0%) or stagnated reductions (≥ - 0.5%) in mortality. The relative risk of mortality generally showed improving trends over time and in successively younger birth cohorts among high and high-middle SDI countries, with the exceptions of Kuwait, Ukraine, Kazakhstan, Guam, RussianFederation, Lithuania, Turkey, Montenegro, Serbia, Bosnia and Herzegovin, and Bulgaria.<br /><b>Interpretation</b><br />Notwithstanding mortality from stroke has increased globally over the past 30 years, adverse period and cohort effects have been found in many countries, calling into question the adequacy of healthcare for stroke patients of all ages. These lapses have a significant impact on the likelihood of achieving the Sustainable Development Goal (SDG) targets on mortality from age 60+ and NCDs.<br /><br />Copyright © 2023.

<div><h4>Spatiotemporal trends in global burden of rheumatic heart disease and associated risk factors from 1990 to 2019.</h4><i>Zhang L, Tong Z, Han R, Li K, Zhang X, Yuan R</i><br /><b>Background</b><br />The aim of this study was to estimate the burden of rheumatic heart disease (RHD) and its trends in different countries, regions, genders and age groups globally.<br /><b>Methods</b><br />Data were obtained from the Global Burden of Disease 2019 study. Age-standardized rates (ASRs) and the estimated annual percentage changes (EAPCs) in the ASRs were used to describe the burden of disease and its trends. Pearson\'s correlation was used to evaluate the correlation between sociodemographic index (SDI) values and the observed trends.<br /><b>Results</b><br />In 2019, the ASRs of the incidence, prevalence, mortality and disability-adjusted life years (DALYs) of RHD were 37.39/10<sup>5</sup> (95%UI, 28.59/10<sup>5</sup> to 46.74/10<sup>5</sup>), 513.68/10<sup>5</sup> (95%UI, 405.01/10<sup>5</sup> to 636.25/10<sup>5</sup>), 3.85/10<sup>5</sup> (95%UI, 4.29/10<sup>5</sup> to 3.29/10<sup>5</sup>) and 132.88/10<sup>5</sup> (95%UI, 115.02/10<sup>5</sup> to 150.34/10<sup>5</sup>), respectively. From 1990 to 2019, the incidence and prevalence of RHD showed upward trends and the mortality and DALYs showed downward trends. Countries or regions in Africa, South America and South Asia had a greater burden of RHD. The burden of RHD was greater in women, where as men showed more obvious increasing trends in the incidence and prevalence. The incidence of RHD was highest in adolescents, and the prevalence was highest in young and middle-aged. The mortality and DALYs rate associated with RHD increased with age. The EAPCs in the ASRs were negatively correlated with the SDI value.<br /><b>Conclusion</b><br />Although the ASRs of mortality and DALYs attributable to RHD are decreasing globally, RHD remains an important public health problem that needs to be addressed urgently, especially in certain low- and middle-income countries and regions.<br /><br />Copyright © 2023.

<div><h4>Polygenic risk scores point toward potential genetic mechanisms of type 2 myocardial infarction in people with HIV.</h4><i>Lee WJ, Cheng H, Whitney BM, Nance RM, ... Hao K, Peter I</i><br /><b>Background</b><br />People with human immunodeficiency virus (HIV) infection (PWH) are at higher risk of myocardial infarction (MI) than those without HIV. About half of MIs in PWH are type 2 (T2MI), resulting from mismatch between myocardial oxygen supply and demand, in contrast to type 1 MI (T1MI), which is due to primary plaque rupture or coronary thrombosis. Despite worse survival and rising incidence in the general population, evidence-based treatment recommendations for T2MI are lacking. We used polygenic risk scores (PRS) to explore genetic mechanisms of T2MI compared to T1MI in PWH.<br /><b>Methods</b><br />We derived 115 PRS for MI-related traits in 9541 PWH enrolled in the Centers for AIDS Research Network of Integrated Clinical Systems cohort with adjudicated T1MI and T2MI. We applied multivariate logistic regression analyses to determine the association with T1MI and T2MI. Based on initial findings, we performed gene set enrichment analysis of the top variants composing PRS associated with T2MI.<br /><b>Results</b><br />We found that T1MI was strongly associated with PRS for cardiovascular disease, lipid profiles, and metabolic traits. In contrast, PRS for alcohol dependence and cholecystitis, significantly enriched in energy metabolism pathways, were predictive of T2MI risk. The association remained after the adjustment for actual alcohol consumption.<br /><b>Conclusions</b><br />We demonstrate distinct genetic traits associated with T1MI and T2MI among PWH further highlighting their etiological differences and supporting the role of energy regulation in T2MI pathogenesis.<br /><br />Copyright © 2023.

Abozied O, Connolly HM</i><br /><b>Background</b><br />Aortic regurgitation (AR) can develop in adults with repaired coarctation of aorta (COA), but there are limited data about left ventricular (LV) remodeling and clinical outcomes in this population. The purpose of the study was to compare LV remodeling (LV mass index [LVMI], LV ejection fraction [LVEF], and septal E/e\') and onset of symptoms before aortic valve replacement, and LV reverse remodeling (%-change in LVMI, LVEF and E/e\') after aortic valve replacement in patients with versus without repaired COA presenting with AR.<br /><b>Methods</b><br />Asymptomatic adults with repaired COA presenting with moderate/severe AR (AR-COA group) were matched 1:2 to asymptomatic adults without COA and similar severity of AR (control group).<br /><b>Results</b><br />Although both groups (AR-COA n = 52, and control n = 104) had similar age, sex, body mass index, aortic valve gradient, and AR severity, the AR-COA group had higher LVMI (124 ± 28 versus 102 ± 25 g/m<sup>2</sup>, p < 0.001) and E/e\' (12.3 ± 2.3 versus 9.5 ± 2.1, p = 0.02) but similar LVEF (63 ± 9% versus 67 ± 10%, p = 0.4). COA diagnosis (adjusted HR 1.95, 95%CI 1.49-2.37, p < 0.001), older age, E/e\', and LV hypertrophy were associated with onset of symptoms. Of 89 patients (AR-COA n = 41, and control n = 48) with echocardiographic data at 1-year post- aortic valve replacement, the AR-COA group had less regression of LVMI (-8% [95%CI -5 to -11] versus -17% [95%CI -15 to -21], p < 0.001) and E/e\' (-5% [95% CI -3 to -7] versus -16% [95% CI -13 to -19], p < 0.001).<br /><b>Conclusions</b><br />Patients with COA and AR had a more aggressive clinical course, and perhaps may require a different threshold for surgical intervention.<br /><br />Copyright © 2023.

<div><h4>The effect of antithrombotic treatment on mortality in patients with acute infection: A meta-analysis of randomized clinical trials.</h4><i>Gazzaniga G, Tavecchia GA, Bravi F, Scavelli F, ... Murthy S, Morici N</i><br /><b>Background:</b><br/>and aims</b><br />Acute infections cause relevant activation of innate immunity and inflammatory cascade. An excessive response against pathogens has been proved to trigger the pathophysiological process of thrombo-inflammation. Nevertheless, an association between the use of antithrombotic agents and the outcome of critically ill patients with infectious diseases is lacking. The aim of this meta-analysis is to determine the impact of antithrombotic treatment on survival of patients with acute infective disease.<br /><b>Methods</b><br />MEDLINE, Embase, Cinahl, Web of Science and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched from inception to March 2021. We included randomized controlled trials (RCTs) that evaluated any antithrombotic agent in patients with infectious diseases other than COVID-19. Two authors independently performed study selection, data extraction and risk of bias evaluation. The primary outcome was all-cause mortality. Summary estimates for mortality were calculated using the inverse-variance random-effects method.<br /><b>Results</b><br />A total of 16,588 patients participating in 18 RCTs were included, of whom 2141 died. Four trials evaluated therapeutic-dose anticoagulation, 1 trial prophylactic-dose anticoagulation, 4 trials aspirin, and 9 trials other antithrombotic agents. Overall, the use of antithrombotic agents was not associated with all-cause mortality (relative risk 0.96; 95% confidence interval, 0.90-1.03).<br /><b>Conclusions</b><br />The use of antithrombotics is not associated with all-cause mortality in patients with infectious disease other than COVID-19.

Alberto M, Eustachio A</i><br /><b>Background</b><br />In terms of pathophysiology, tricuspid regurgitation (TR), right ventricular function and pulmonary artery pressure are linked to each other. Our aim was to analyze whether the echocardiography-derived right ventricular free wall longitudinal strain/pulmonary artery systolic pressures (RVFWLS/PASP) ratio can improve risk stratification in patients with severe tricuspid regurgitation (TR).<br /><b>Methods</b><br />In this single-center retrospective study, 250 consecutive patients with severe TR were enrolled from December 2015 to December 2018. Baseline clinical and echocardiographic parameters were collected. Echocardiography-derived TAPSE/PASP and RVFWLS/PASP were evaluated. The primary endpoint was all-cause mortality.<br /><b>Results</b><br />Out of 250 consecutive patients, 171 meet inclusion criteria. Patients were predominantly female, with several cardiovascular risk factors and comorbidities. RVFWLS/PASP ≤0.34%/mmHg (AUC 0.68, p < 0.001, sensitivity 70%, specificity 67%) was associated with baseline clinical RV heart failure (p = 0.03). After univariate and multivariate analyses, RVFWLS/PASP, but not TAPSE/PASP, independently correlated with all-cause mortality (HR 0.004, p = 0.02). Patients with RVFWLS/PASP >0.26%/mmHg (AUC 0.74, p < 0.001, sensitivity 77%, specificity 52%) showed higher survival rates (p = 0.02). In addition at 24 months follow-up, the Kaplan-Meyer curves showed patients with RVFWLS >14% & RVFWLS/PASP >0.26%/mmHg had the best survival rate compared to patients without.<br /><b>Conclusion</b><br />RVFWLS/PASP is independently associated with baseline RV heart failure and poor long-term prognosis in patients with severe TR.<br /><br />Copyright © 2023.

<div><h4>Disparities in the management of non-ST-segment elevation myocardial infarction in the United States.</h4><i>Varma Y, Jena NK, Arsene C, Patel K, Sule AA, Krishnamoorthy G</i><br /><AbstractText>Guidelines recommend managing patients aged ≥75 with non-ST-segment elevation myocardial infarction (NSTEMI) similar to younger patients. We analyze disparities in NSTEMI management and compare those ≥80 years to those <80 years. This is a matched case-control study using the 2016 National Inpatient Sample data of adults with NSTEMI receiving percutaneous coronary intervention with drug-eluting stent (PCI-DES) - one artery or no intervention. We included the statistically significant variables in univariate analysis in exploratory multivariate logistic regression models. Total sample included 156,328 patients, out of which 43,265 were ≥ 80 years, and 113,048 were < 80 years. Patients ≥80 years were more likely to not have an intervention (73.3%) when compared to those <80 (44.1%), P < 0.0005. Regardless of age, PCI-DES-one artery improved survival compared to no intervention (Age < 80: OR 0.230, 95% CI 0.189-0.279, and ≥ 80: OR 0.265, 95% CI 0.195-0.361, P < 0.0005). Women (OR 0.785, 95% CI 0.766-0.804, P < 0.0005) and non-white race (OR 0.832, 95% CI 0.809-0.855, P < 0.0005) were less likely to receive an intervention. Non-Medicare/Medicaid insurance was associated with 40% lower likelihood of dying in <80 age group (OR 0.596, 95% CI 0.491-0.724, P < 0.0005), and 16% higher chance of intervention overall (OR 1.160, 95% CI 1.125-1.197, P < 0.0005). Patients aged ≥80 with NSTEMI were 29% less likely to receive an intervention compared to patients aged <80, even though patients >80 derived similar mortality benefits from the intervention.

Using a multivariate Cox model, we compared the mortality of patients with mPAP<sub>20-25mmHg</sub>, and mPAP<sub>≥25mmHg</sub> versus those with mPAP<sub>≤20mmHg</sub>.<br /><b>Results</b><br />Of 693 patients with chronic HF considered for heart transplantation, 12.7%, 77.5% and 9.8% were classified as mPAP<sub>20-25mmHg</sub>, mPAP<sub>≥ 25mmHg</sub> and mPAP<sub>≤20mmHg</sub>. Patients of mPAP ≥ <sub>25mmHg</sub> and mPAP <sub>20-25 mmHg</sub> categories were older than mPAP ≤ <sub>20 mmHg</sub> (56 versus 55 and 52 year-old, p = 0.02) with more frequent co-morbidities. Within 2.8 years, the mPAP<sub>20-25mmHg</sub> category displayed a higher risk of mortality compared with those of the mPAP<sub>≤20mmHg</sub> category (aHR 2.75, 95% CI 1.27-5.97, p = 0.01).

Demographic, clinical, and biochemical variables were collected at baseline and during hospital stay.<br /><b>Results</b><br />Eighty-eight patients were consecutively recruited. The predominant etiologies were idiopathic dilated cardiomyopathy (47%), followed by post-ischemic (24%). AKI was diagnosed in 70 (79.5%) of patients. Forty-three out of 70 patients met the criteria for AKI at ICU admission. On multivariate analysis, a central venous pressure (CVP) higher than 10 mmHg (OR 3.9; 95%CI 1.2-12.6; p = 0.025) and serum lactate higher than 3 mmol/L (OR 4.1; 95%CI 1.01-16.3; p = 0.048) were identified to be independently associated with AKI. Age and AKI stage were independent predictors of 90-day mortality.<br /><b>Conclusion</b><br />AKI is a common and early complication of ADHF-CS. Venous congestion and severe hypoperfusion are risk factors for AKI development. Early detection and prevention of AKI could lead to better outcome in this clinical subgroup.<br /><br />Copyright © 2023.

<div><h4>Application of machine learning algorithms in electronic medical records to predict amputation-free survival after first revascularization in patients with peripheral artery disease.</h4><i>Liu Y, Xue J, Jiang J</i><br /><b>Background</b><br />This study aimed to apply eight machine learning algorithms to develop the optimal model to predict amputation-free survival (AFS) after first revascularization in patients with peripheral artery disease (PAD).<br /><b>Methods</b><br />Among 2130 patients from 2011 to 2020, 1260 patients who underwent revascularization were randomly assigned to training set and validation set in an 8:2 ratio. 67 clinical parameters were analyzed by lasso regression analysis. Logistic regression, gradient boosting machine, random forest, decision tree, eXtreme gradient boosting, neural network, Cox regression, and random survival forest (RSF) were applied to develop prediction models. The optimal model was compared with GermanVasc score in testing set comprising patients from 2010.<br /><b>Results</b><br />The postoperative 1/3/5-year AFS were 90%, 79.4%, and 74.1%. Age (HR:1.035, 95%CI: 1.015-1.056), atrial fibrillation (HR:2.257, 95%CI: 1.193-4.271), cardiac ejection fraction (HR:0.064, 95%CI: 0.009-0.413), Rutherford grade ≥ 5 (HR:1.899, 95%CI: 1.296-2.782), creatinine (HR:1.03, 95%CI: 1.02-1.04), surgery duration (HR:1.03, 95%CI: 1.01-1.05), and fibrinogen (HR:1.292, 95%CI: 1.098-1.521) were independent risk factors. The optimal model was developed by RSF algorithm, with 1/3/5-year AUCs in training set of 0.866 (95% CI:0.819-0.912), 0.854 (95% CI:0.811-0.896), 0.844 (95% CI:0.793-0.894), in validation set of 0.741 (95% CI:0.580-0.902), 0.768 (95% CI:0.654-0.882), 0.836 (95% CI:0.719-0.953), and in testing set of 0.821 (95%CI: 0.711-0.931), 0.802 (95%CI: 0.684-0.919), 0.798 (95%CI: 0.657-0.939).

<div><h4>Temporal trends in the prevalence and severity of aortic stenosis within a contemporary and diverse community-based cohort.</h4><i>Ambrosy AP, Go AS, Leong TK, Garcia EA, ... Berry N, Solomon MD</i><br /><b>Background</b><br />Data on the epidemiology of aortic stenosis (AS) are primarily derived from single center experiences and administrative claims data that do not delineate by degree of disease severity.<br /><b>Methods</b><br />An observational cohort study of adults with echocardiographic AS was conducted January 1st, 2013-December 31st, 2019 at an integrated health system. The presence/grade of AS was based on physician interpretation of echocardiograms.<br /><b>Results</b><br />A total of 66,992 echocardiogram reports for 37,228 individuals were identified. The mean ± standard deviation (SD) age was 77.5 ± 10.5, 50.5% (N = 18,816) were women, and 67.2% (N = 25,016) were non-Hispanic whites. The age-standardized AS prevalence increased from 589 (95% Confidence Interval [CI] 580-598) to 754 (95% CI 744-764) cases per 100,000 during the study period. The age-standardized AS prevalences were similar in magnitude among non-Hispanic whites (820, 95% CI 806-834), non-Hispanic blacks (728, 95% CI 687-769), and Hispanics (789, 95% CI 759-819) and substantially lower for Asian/Pacific Islanders (511, 95% CI 489-533).

<div><h4>Risk stratification of patients with chest pain who have an unscheduled revisit to the emergency department.</h4><i>Ho YJ, Chen CH, Sung CW, Fan CY, ... Chen JW, Edward Pei-Chang Huang S</i><br /><b>Aims</b><br />Acute cardiovascular (CV) emergencies are critical conditions that require urgent attention in the emergency department (ED). Failure to make a timely diagnosis may result in unscheduled ED revisits and severe outcomes. Therefore, this study aimed to investigate the risk factors associated with potentially missed acute CV emergencies.<br /><b>Methods and results</b><br />This retrospective study enrolled adult patients who presented with chest pain and returned to the ED within 72 h. Demographic information, pre-existing medical conditions, chief complaints, triage level and vital signs, electrocardiography (ECG) reports, and laboratory data were collected from medical charts by independent physicians. The primary outcome was the diagnosis of acute CV diseases, including ACS, pulmonary embolism, unstable arrhythmia, acute decompensated heart failure, and aortic dissection. Multivariable logistic regression was used to analyze the association between variables and acute CV emergencies. A total of 453 eligible patients were included, with 60 (13.2%) patients diagnosed as acute CV emergencies at the ED revisit. Risk factors for acute CV emergencies included male gender (adjusted odds ratio [aOR] = 2.71, 95% confidence interval [CI] = 1.17-6.25), abnormal ECG rhythm (aOR = 10.33, 95% CI = 4.68-22.83), and abnormal changes in high sensitivity Troponin-T (hs-cTnT) during sequential follow-up (aOR = 6.52, 95% CI = 2.19-19.45).<br /><b>Conclusions</b><br />Male gender, abnormal ECG rhythm, and a significant increase in sequential follow-up hs-cTnT levels were identified as significant risk factors for acute CV emergencies. ED physicians should recognize these high-risk patients with chest pain to prevent misdiagnosis and potential severe complications.<br /><br />Copyright © 2023.

<div><h4>Multielectrode mapping for premature ventricular contraction ablation - A prospective, multicenter study.</h4><i>Sousa PA, Barra S, Cortez-Dias N, Khoueiry Z, ... Garcia FC, Gonçalves L</i><br /><b>Purpose</b><br />We aim to evaluate whether the use of a multielectrode mapping catheter could lead to higher efficacy of premature ventricular contraction (PVC) ablation.<br /><b>Methods</b><br />Prospective, multicenter nonrandomized study of consecutive patients referred for PVC ablation from January 2018 to June 2021. Patients were separated into two groups: activation map performed with the PentaRay catheter (Study group) or with the ablation catheter (Control group). PMF software was used in both groups. Procedural endpoints and 1-year freedom from ventricular arrhythmia were assessed.<br /><b>Results</b><br />During the enrollment period 136 patients (60% males, mean age of 55 ± 17 years, 60% left-sided origin) fulfilled the inclusion criteria - 68 patients in each group. Patients in the Study Group had a sevenfold higher number of acquired activation points (768 ± 728 vs. 110 ± 79, p < 0.01), a shorter mapping time (28 ± 19 min vs. 49 ± 32 min, p < 0.01) and a quicker procedure time (110 ± 33 min vs. 134 ± 50 min, p < 0.01), compared to patients in the Control Group. While there were no significant differences in the acute success (95.6% in the Study Group vs. 90.1% in Control group, p = 0.49), or adverse events (4% in the Study group vs. 7% in the Control group, p = 0.72), patients in the Study group had a higher freedom from ventricular arrhythmia at 1-year (89.7% vs. 70.6%, p = 0.01). The use of the PentaRay catheter was an independent predictor of success (HR = 6.20 [95% CI, 1.08-35.47], p = 0.003).<br /><b>Conclusions</b><br />The use of the PentaRay catheter may improve the outcome of PVC ablation while reducing procedure time.<br /><br />Copyright © 2023.

<div><h4>Echocardiographic findings in cardiogenic shock due to acute myocardial infarction versus heart failure.</h4><i>Singam NSV, Tabi M, Wiley B, Anavekar N, Jentzer J</i><br /><b>Background</b><br />Acute myocardial infarction (AMI) is the prototypical cause of cardiogenic shock (CS), yet CS due to heart failure (HF-CS) is increasingly common. Little is known regarding cardiac function in AMI-CS versus HF-CS. We compared transthoracic echocardiography (TTE) findings in AMI-CS versus HF-CS and identified predictors of mortality in AMI-CS patients.<br /><b>Methods</b><br />We performed a single-center, retrospective analysis of CS admissions between 2007 and 2018. We compared baseline demographic and TTE parameters in patients with AMI-CS and HF-CS as well as ST elevation myocardial infarction (STEMI)-CS versus non-ST elevation myocardial infarction (NSTEMI)-CS.<br /><b>Results</b><br />We included 893 unique patients, including 581 (65%) with AMI-CS. AMI-CS patients were older but had lower illness severity and non-cardiac comorbidity burden. AMI-CS patients had better left ventricular function (LVEF 35% versus 28%), lower biventricular filling pressures, and higher stroke volume versus those with HF-CS. Among TTE measurements, myocardial contraction fraction had the highest discrimination for mortality in AMI-CS (AUC: 0.64); AUC values for LVEF and SOFA score were 0.61 and 0.65, respectively. Differences in TTE findings between STEMI-CS versus NSTEMI-CS were modest. There were no significant differences in unadjusted or adjusted in-hospital mortality between AMI-CS and HF-CS (31% versus 35%) or STEMI-CS and NSTEMI-CS (31% versus 30%) groups (all p > 0.05).<br /><b>Conclusions</b><br />Patients with HF-CS and AMI-CS differ in terms of clinical and TTE variables yet have similar prognoses. TTE is useful in determining prognosis of patients admitted with AMI-CS and may allow for early triage and directed therapy.<br /><br />Copyright © 2023.

<div><h4>Herbal medicines for the treatment of cardiovascular diseases: Benefits and risks- A narrative review.</h4><i>Villaescusa L, Zaragoza C, Zaragoza F, Tamargo J</i><br /><AbstractText>Herbal medicines (HMs) have been traditionally used for the prophylaxis/treatment of cardiovascular diseases (CVDs). Their use is steadily increasing and many patients with CVDs often combine HMs with prescribed cardiovascular medications. Interestingly, up to 70% of patients do not notify cardiologists/physicians the use of HMs and up to 90% of cardiologists/physicians may not routinely inquire them about the use of HMs. There is limited scientific evidence from well-designed clinical trials supporting the efficacy and safety of HMs and because they do not reduce morbidity and mortality are not recommended in clinical guidelines for the prophylaxis/treatment of CVDs. There is also a great deal of confusion about the identification, active constituents and mechanisms of action of HMs; the lack of standardization and quality control (contaminations, adulterations) represent other sources of concern. Furthermore, the widespread perception that unlike prescription drugs HMs are safe is misleading and some HMs can cause clinically relevant adverse events and interactions, particularly when used with narrow therapeutic index prescribed cardiovascular drugs (antiarrhythmics, antithrombotics, digoxin). Cardiologists/physicians can no longer ignore the problem. They must improve their knowledge about the HMs their patients consume to provide the best advice and prevent adverse reactions and drug interactions. This narrative review addresses the putative mechanisms of action, suggested clinical uses and safety of most commonly used HMs, the pivotal role of cardiologists/physicians to protect consumers and the main challenges and gaps in evidence related to the use of HMs in the prophylaxis and treatment of CVDs.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Single-pill combination in the management of chronic coronary syndromes: A strategy to improve treatment adherence and patient outcomes?</h4><i>Pinto FJ, Piepoli MF, Ferrari R, Tsioufis K, ... Nedoshivin A, Kaski JC</i><br /><AbstractText>Chronic coronary syndrome (CCS) represents a major challenge for physicians, particularly in the context of an increasing aging population. Additionally, CCS is often underestimated and under-recognised, particularly in female patients. As patients are frequently affected by several chronic comorbidities requiring polypharmacy, this can have a negative impact on patients\' adherence to treatment. To overcome this barrier, single-pill combination (SPC), or fixed-dose combination, therapies are already widely used in the management of conditions such as hypertension, dyslipidaemia, and diabetes mellitus. The use of SPC anti-anginal therapy deserves careful consideration, as it has the potential to substantially improve treatment adherence and clinical outcomes, along with reducing the failure of pharmacological treatment before considering other interventions in patients with CCS.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Socioeconomic deprivation and prognostic outcomes in acute coronary syndrome: A meta-analysis using multidimensional socioeconomic status indices.</h4><i>Anand VV, Zhe ELC, Chin YH, Goh RSJ, ... Mamas MA, Chew NWS</i><br /><b>Background</b><br />Low socioeconomic status (SES) is an important prognosticator amongst patients with acute coronary syndrome (ACS). This paper analysed the effects of SES on ACS outcomes.<br /><b>Methods</b><br />Medline and Embase were searched for articles reporting outcomes of ACS patients stratified by SES using a multidimensional index, comprising at least 2 of the following components: Income, Education and Employment. A comparative meta-analysis was conducted using random-effects models to estimate the risk ratio of all-cause mortality in low SES vs high SES populations, stratified according to geographical region, study year, follow-up duration and SES index.<br /><b>Results</b><br />A total of 29 studies comprising of 301,340 individuals were included, of whom 43.7% were classified as low SES. While patients of both SES groups had similar cardiovascular risk profiles, ACS patients of low SES had significantly higher risk of all-cause mortality (adjusted HR:1.19, 95%CI: 1.10-1.1.29, p < 0.001) compared to patients of high SES, with higher 1-year mortality (RR:1.08, 95%CI:1.03-1.13, p = 0.0057) but not 30-day mortality (RR:1.07, 95%CI:0.98-1.16, p = 0.1003). Despite having similar rates of ST-elevation myocardial infarction and non-ST-elevation ACS, individuals with low SES had lower rates of coronary revascularisation (RR:0.95, 95%CI:0.91-0.99, p = 0.0115) and had higher cerebrovascular accident risk (RR:1.25, 95%CI:1.01-1.55, p = 0.0469). Excess mortality risk was independent of region (p = 0.2636), study year (p = 0.7271) and duration of follow-up (p = 0.0604) but was dependent on the SES index used (p < 0.0001).<br /><b>Conclusion</b><br />Low SES is associated with increased mortality post-ACS, with suboptimal coronary revascularisation rates compared to those of high SES. Concerted efforts are needed to address the global ACS-related socioeconomic inequity.<br /><b>Registration and protocol</b><br />The current study was registered with PROSPERO, ID: CRD42022334482.<br /><br />Copyright © 2023.

<div><h4>Interrelations between albuminuria, electrocardiographic left atrial abnormality, and incident atrial fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.</h4><i>Ahmad MI, Chen LY, Singh S, Luqman-Arafath TK, Kamel H, Soliman EZ</i><br /><b>Background</b><br />The objective of the study was to examine the joint associations of albuminuria and electrocardiographic left atrial abnormality (ECG-LAA) with incident atrial fibrillation (AF) and whether this relationship varies by race.<br /><b>Methods</b><br />This analysis included 6670 participants free of clinical cardiovascular disease (CVD), including atrial fibrillation (AF), from the Multi-Ethnic Study of Atherosclerosis. ECG-LAA was defined as P-wave terminal force in V1 [PTFV1] >5000 μV × ms. Albuminuria was defined as urine albumin-creatinine ratio (UACR) ≥30 mg/g. Incident AF events through 2015 were ascertained from hospital discharge records and study-scheduled electrocardiograms. Cox proportional hazard models were used to examine the association of \"no albuminuria + no ECG-LAA (reference)\", \"isolated albuminuria\", \"isolated ECG-LAA\" and \"albuminuria + ECG-LAA\" with incident AF.<br /><b>Results</b><br />Over a median follow-up of 13.8 years, 979 incident cases of AF occurred. In adjusted models, the concomitant presence of ECG-LAA and albuminuria was associated with a higher risk of AF than either ECG-LAA or albuminuria in isolation (HR (95% CI): 2.43 (1.65-3.58), 1.33 (1.05-1.69), and 1.55 (1.27-1.88), respectively (interaction p-value = 0.50). Effect modification by race was observed with a 4-fold greater AF risk in Black participants with albuminuria + ECG-LAA (HR (95%CI): 4.37 (2.38-8.01) but no significant association in White participants (HR (95% CI) 0.60 (0.19-1.92) respectively; (interaction p-value for race x albuminuria-ECG-LAA combination = 0.05).<br /><b>Conclusions</b><br />Concomitant presence of ECG-LAA and albuminuria confers a higher risk of AF compared to either one in isolation with a stronger association in Blacks than Whites.<br /><br />Copyright © 2023.

<div><h4>Congenital heart disease and the risk of impaired fertility: A Danish nationwide cohort study using time to pregnancy.</h4><i>Udholm LF, Ebdrup NH, Arendt LH, Knudsen UB, Hjortdal VE, Ramlau-Hansen CH</i><br /><b>Background</b><br />The number of women with congenital heart disease (CHD) becoming pregnant are increasing. Although menstrual irregularities appear to occur more often in these patients, knowledge on their fertility is limited. In this nationwide cohort study, we evaluated the risk of impaired fertility in women with CHD compared with unaffected women using time to pregnancy (TTP).<br /><b>Methods</b><br />The Danish National Birth Cohort (DNBC) of pregnant women constituted the study population. Information on TTP and use of medically assisted reproduction (MAR) treatment was reported at a first trimester interview. Women with CHD were identified by linkage to the Danish National Patient Registry. TTP was divided into three categories; 0-5 months, 6-12 months (i.e. subfertile), and > 12 months or use of MAR treatment (i.e. infertile). Relative risk ratios (RRR) for subfertility and infertility with 95% confidence intervals were estimated using multinomial logistic regression.<br /><b>Results</b><br />Among 93,832 pregnancies in 84,922 women, CHD was diagnosed in 333 women (0.4%), contributing with 360 pregnancies. The CHD was of simple complexity in 291 women (87.4%). No association was found between CHD and longer TTP (RRR of 1.02 (95% CI: 0.75-1.40) for subfertility, and RRR of 0.86 (95% CI: 0.61-1.20) for infertility). Similar was observed when comparing women with simple CHD and unaffected women. The number of women with complex CHD was too low for evaluation.<br /><b>Conclusions</b><br />Women with CHD had no increased risk of impaired fertility, assessed by TTP, when compared with unaffected women.

<div><h4>Evaluating subclinical left ventricular and left atrial dysfunction in idiopathic atrial fibrillation: A speckle-tracking based strain-analysis.</h4><i>van Mourik MJW, Linz D, Verwijs HJA, Bekkers SCAM, ... Weijs B, Knackstedt C</i><br /><b>Objective</b><br />A subset of patients with atrial fibrillation (AF) presents without established AF risk factors and normal left ventricular (LV) systolic function, called idiopathic AF (IAF). Traditionally, echocardiography derived LV dimensions and ejection fraction (EF) are used to exclude LV dysfunction in IAF, but their sensitivity is limited. Our objective is to evaluate the presence of subtle alterations in LV function despite normal LVEF in patients with IAF compared to healthy controls, using speckle-tracking echocardiography (STE) based global longitudinal strain (GLS).<br /><b>Methods</b><br />Standard transthoracic echocardiography was performed in 80 patients with IAF and 129 healthy controls. Patients with overt cardiac disease as well as known established AF risk factors were excluded. STE analysis was performed to assess GLS of the LV, and left atrial strain (LAS).<br /><b>Results</b><br />LVEF was normal and comparable between patients with IAF and healthy controls (63 ± 4% for both groups; p = 0.801). Mean GLS was within normal limits for both groups but statistically significantly more negative in patients with IAF (-20.6 ± 2.5% vs. -19.7 ± 2.5%; p = 0.016), however not when indexed for ventricular cycle length (p = 0.784). No differences in LA volume or non-indexed LAS were seen in patients with IAF compared to healthy controls.<br /><b>Conclusions</b><br />In this selected group of IAF patients, STE did not detect any overt LV or LA dysfunction compared to healthy controls. Thus, IAF occurred in these patients not only in the absence of established AF risk factors but also without evidence of ventricular dysfunction.<br /><br />Copyright © 2023.

<div><h4>The association between myocardial ischemia and myocardial dysfunction in adult patients with systemic right ventricle - A single centre multimodality study.</h4><i>Pavsic N, Zbacnik R, Berden P, Kacar P, ... Salobir BG, Prokselj K</i><br /><b>Background</b><br />The exact interaction of factors leading to myocardial dysfunction and fibrosis of the systemic right ventricle (SRV) is not completely understood. Myocardial ischemia and injury associated with a supply-demand mismatch of the pressure overloaded SRV are thought to play an important role, however studies confirming this are lacking.<br /><b>Methods</b><br />Adult SRV patients were included in this single centre cohort study. All patients underwent a comprehensive diagnostic and imaging workup. A two-day stress-rest SPECT was performed to assess myocardial perfusion. SRV ischemia was defined as decreased segmental tracer uptake during exercise with significant improvement at rest. Contrast enhanced cardiac magnetic resonance imaging (CMR) was also performed in a subgroup of patients without contraindication, to assess focal myocardial fibrosis. Differences between patients with and without SRV ischemia were assessed.<br /><b>Results</b><br />Twenty-three SRV patients (15 with transposition of the great arteries after atrial switch procedure and 8 with congenitally corrected transposition of the great arteries; 5 (22%) females; mean age 38 ± 11 years) were included. Seven (30%) patients had SRV ischemia on SPECT. Late gadolinium enhancement on CMR was more common in patients with SRV ischemia (p = 0.002). However, there was no association between SRV ischemia and different echocardiographic or CMR parameters of SRV systolic function, laboratory markers (high-sensitivity troponin I and NT-proBNP) and exercise capacity.<br /><b>Conclusions</b><br />Our multimodality study showed that SRV ischemia in adult SRV patients was associated with more focal myocardial fibrosis, but not with functional or imaging markers of SRV function.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Accuracy of the angiography-based quantitative flow ratio in intermediate left main coronary artery lesions and comparison with visual estimation.</h4><i>Lopez-Palop R, Carrillo P, Leithold G, Lozano I, ... Pinar E, Pascual D</i><br /><b>Background</b><br />Revascularization of left main coronary artery (LMCA) stenosis is mostly based on angiography. Indices based on angiography might increase accuracy of the decision, although they have been scarcely used in LMCA. The objective of this study is to study the diagnostic agreement of QFR (quantitative flow ratio) with wire-based fractional flow reserve (FFR) in LMCA lesions and to compare with visual severity assessment.<br /><b>Methods</b><br />In a series of patients with invasive FFR assessment of intermediate LMCA stenoses we retrospectively compared the measured value of QFR with that of FFR and the estimate of significance from angiography.<br /><b>Results</b><br />107 QFR studies were included. The QFR intra-observer and inter-observer agreement was 87% and 82% respectively. The mean QFR-FFR difference was 0.047 ± 0.05 with a concordance of 90.7%, sensitivity 88.1%, specificity 92.3%, positive predictive value 88.1% and negative predictive value 92.3%. All these values were superior to those observed with the visual estimation which showed an intra- and inter-observer agreement of 73% and 72% respectively, besides 78% with the FFR value. The low diagnostic performance of the visual estimation and the acceptable performance of the QFR index measurement were observed in all subgroups analysed.<br /><b>Conclusions</b><br />QFR allows an acceptable estimate of the FFR obtained with intracoronary pressure guidewire in intermediate LMCA lesions, and clearly superior to the assessment based on angiography alone. The decision to revascularize patients with moderate LMCA lesions should not be based solely on the degree of angiographic stenosis.<br /><br />Copyright © 2023.

<div><h4>Long-term outcomes of patients treated with sirolimus-eluting resorbable magnesium scaffolds: Insights from the SHERPA-MAGIC study.</h4><i>Pompei G, Campo G, Ruggiero R, Maffeo D, ... Varbella F, Cerrato E</i><br /><b>Background</b><br />The resorbable magnesium scaffold (RMS) is a second-generation bioresorbable scaffold (BRS) that has shown conflicting results in previous studies. These findings suggest that patient selection and implantation technique may have an impact on clinical outcomes. This study aimed to investigate the safety and long-term effectiveness of RMS in a narrowly selected population.<br /><b>Methods</b><br />SHERPA-MAGIC is an investigator-driven, multicenter, prospective, single-arm study that enrolled patients undergoing BRS coronary implantation in 18 Italian centers. The present analysis considered the first 543 enrolled patients treated with RMS, with a minimum follow-up of 1 year. The study protocol included strict criteria for patient selection and standardization of RMS implantation. The primary outcome was the occurrence of the vessel-oriented composite endpoints (VOCE), including cardiac death, target vessel myocardial infarction, and ischemia-driven target vessel revascularization.<br /><b>Results</b><br />Overall, 635 vessels were treated. The 1-year cumulative occurrence of VOCE was 22 (3.5%, 95% CI 2.2%-5.2%), which was significantly lower than the prespecified estimation (from 5.5% to 8.5%). At the median follow-up of 3.5 [2.6-4.3] years, there were 3 (0.5%) cardiac deaths, 12 (1.9%) target vessel myocardial infarctions, and 33 (5.2%) ischemia-driven target vessel revascularizations. A total of 37 (5.8%, 95%CI 4.1%-7.9%) VOCEs were detected. Scaffold thrombosis occurred in 4 (0.6%, 95%CI 0.1%-1.6%) cases. Patient-level analysis confirmed the findings of the vessel-level analysis.<br /><b>Conclusions</b><br />These results confirm the safety and performance of RMS technology. If confirmed in randomized controlled trials, they may rekindle interest in the use of scaffolds in daily practice.<br /><br />Copyright © 2023.

Abstract
<div><h4>Association between institutional volume of transcatheter mitral valve repair and readmission rates: A report from the National Readmission Database.</h4><i>Shoji S, Kuno T, Malik A, Briasoulis A, ... Kohsaka S, Latib A</i><br /><b>Background</b><br />Transcatheter edge-to-edge repair (TEER) of the mitral valve has become an established therapy for certain patients with mitral regurgitation. However, little is known about the association between institutional volume variations and long-term outcomes using a large-scale database. Our study aimed to describe the institutional variations of TEER and also investigate its association with 180-day readmission rates.<br /><b>Methods</b><br />We conducted a retrospective cohort study of TEER performed in the US from the 2019 Nationwide Readmission Database. We divided the patients according to the tertiles based on volume of TEER (Q1 [lowest]-Q3 [highest]) and evaluated the association with 180-day readmission rates.<br /><b>Results</b><br />A total of 4922 patients (mean age 76.8 ± 10.4 years, and 54.5% male) who underwent TEER at 250 institutions were included in the analyses. There was substantial variation in the number of TEER performed annually across institutions (median 25.0 [11.6-52.5] cases). Readmission within 6-months following TEER was 37.0%, mainly due to heart failure. Higher institutional volume was associated with a reduced incidence of 180-day readmissions (HR of Q3 0.58 95%CI 0.38-0.90, vs Q1; p = 0.015). This association was more prominent in non-elective cases (HR of Q3 0.33 95%CI 0.15-0.72, vs Q1; p = 0.005).<br /><b>Conclusions</b><br />Using a nationally representative contemporary database, our study found substantial institutional variation in volume of TEER cases. Higher institutional volume was associated with a decreased risk of 180-day readmission rate, particularly in non-elective cases. Our study suggests the importance of highly skilled heart teams when treating patients who need urgent transcatheter intervention for mitral regurgitation.<br /><br />Copyright © 2023.

Abstract
<div><h4>Identification of acute aortic syndromes based on cross-sectional variability of Hounsfield units.</h4><i>Chen PH, Nakamura K, Obuchowski N, Juan MC, ... Meese T, Schoenhagen P</i><br /><b>Background</b><br />A characteristic feature of communicating aortic dissections (CD) is the dissection flap between the true and false lumen. However, in intramural hematomas (IMH) a flap is not visible. We aimed to determine if cross-sectional HU variability allow reliable identification of aortic dissections including IMH.<br /><b>Methods</b><br />We included 362 patients presenting with acute chest pain (CP) or respiratory distress (RD) and underwent contrast-enhanced CTA with or without ECG-gating. In the derivation group we included 72 CP patients with and 74 without AAS. In the validation group we included 108 CP or RD patients with and 108 without AAS. The adventitial border of the aorta was visually identified and measurements were performed at 6 locations along the ascending and descending aorta. At each cross-section 5 circular ROI measurements of HU were made and the maximum HU difference calculated.<br /><b>Results</b><br />In the derivation and validation group the maximum difference in HUs at any one location was significantly higher for AAS subjects than controls (validation group: median = 128.5 vs. 34.0, p-value Wilcoxon two-sample test <0.001). In the validation group, the estimated AUC was 0.939 with 95% CIs of [0.906, 0.972], indicating that the maximum difference in HUs is a strong predictor of AAS (p < 0.001).<br /><b>Conclusion</b><br />Our data provide evidence that cross-sectional variability of Hounsfield Unit reliably identifies aortic dissection including IMH in dedicated ECG-gated aorta scans but also non-gated chest CTs with limited aortic contrast enhancement. These results suggest that this approach could be feasible for an automated algorithm for identification of AAS.<br /><br />Copyright © 2023.

<div><h4>Biolimus-eluting vs. other limus-eluting stents in NSTE-ACS: A pooled analysis of glassy and twilight.</h4><i>Spirito A, Valgimigli M, Cao D, Baber U, ... Pocock S, Mehran R</i><br /><b>Background</b><br />Biodegradable polymer biolimus-eluting stents (BP-BES) may be associated with better outcomes in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) compared to other current-generation limus-eluting stents (LES).<br /><b>Aims</b><br />To compare BP-BES with other current-generation LES in ACS patients undergoing PCI.<br /><b>Methods</b><br />We pooled individual data of Non-ST-segment elevation (NSTE)-ACS patients from two large randomized controlled trials (GLASSY and TWILIGHT). The BP-BES groups consisted mostly of GLASSY patients, while the control group (other current-generation LES) included exclusively TWILIGHT patients. The primary outcome was major adverse cardiovascular events (MACE), including cardiovascular death, myocardial infarction, or stent thrombosis; the key secondary outcome was target-vessel failure (TVF). To account for trial design differences, outcomes were assessed at 3 months (short-term) and between 3 and 12 months (long-term) after PCI and subsequently pooled to estimate the 12-month hazards.<br /><b>Results</b><br />Of 7107 and 6053 NSTE-ACS patients included in the short- and long-term analysis, 32.7% and 36.5% received a BP-BES, respectively. Risk of MACE associated with BP-BES versus other LES was similar at short-term (1.1% vs 1.4%, adjusted HR 0.81, 95%CI 0.51-1.29), lower at long-term (1.7% vs 3.1%, adjusted HR 0.46, 95%CI 0.32-0.67), and lower in the entire 12-month period (pooled adjusted HR 0.58, 95%CI 0.43-0.77). The cumulative 12-month risk of TVF was reduced with BP-BES (adjusted HR 0.52, 95%CI 0.38-0.70).<br /><b>Conclusion</b><br />BP-BES was associated with lower 12-month risks of MACE and TVF compared to other current generation LES among NSTE-ACS patients treated with abbreviated or standard ticagrelor-based DAPT. These non-randomized findings are hypothesis-generating.<br /><b>Condensed abstract</b><br />Differences in clinical outcomes may exist between biodegradable polymer biolimus-eluting stents (BP-BES) and other current-generation limus-eluting stent (LES) in patients with acute coronary syndrome (ACS). We pooled individual data of about 7000 Non-ST-segment elevation ACS patients undergoing PCI and treated with ticagrelor with or without aspirin from two large randomized controlled trials (GLASSY and TWILIGHT). BP-BES patients derived very largely from GLASSY and other LES patients from TWILIGHT. In this population, BP-BES compared to other current generation LES, were associated with a lower 12-month risk of major adverse cardiovascular events and target-vessel failure.<br /><br />Copyright © 2023.

<div><h4>Early and late onset cardiotoxicity following anthracycline-based chemotherapy in breast cancer patients: Incidence and predictors.</h4><i>Serrano JM, Mata R, González I, Del Castillo S, ... Guerra JA, Alonso JJ</i><br /><b>Introduction</b><br />Cardiotoxicity represents a major limitation for the use of anthracyclines or trastuzumab in breast cancer patients. Data on longitudinal studies about early and late onset cardiotoxicity in this group of patients is scarce. The objective of the present study was to assess predictors of early and late onset cardiotoxicity in patients with breast cancer treated with A.<br /><b>Methods</b><br />100 consecutive patients receiving anthracycline-based chemotherapy (CHT) to treat breast cancer were included in this prospective study. All patients underwent evaluation at baseline, at the end of CHT, 3 months after the end of CHT and 1 and 4 years after the beginning of CHT. Clinical data, systolic and diastolic echo parameters and cardiac biomarkers including high sensitivity Troponin T (TnT), N-terminal pro-brain natriuretic peptide (NT-proBNP) and Heart-type fatty acid binding protein (H-FABP) were assessed.<br /><b>Results</b><br />Mean doxorubicin dose was 243 mg/m2. Mean follow-up was 51.8 ± 8.2 months. At one-year incidence of anthracycline related-cardiotoxicity (AR-CT) was 4% and at the end of follow-up was 18% (15 patients asymptomatic left ventricular systolic dysfunction, 1 patients heart failure and 2 patients a sudden cardiac death). Forty-nine patients developed diastolic dysfunction (DD) during first year. In the univariate analysis DD during first year was the only parameter associated with AR-CT (Table 1). In the logistic regression model DD was independently related with the development of AR-CT, with an odds ratio value of 7.5 (95% CI 1.59-35.3).<br /><b>Conclusions</b><br />Incidence of late-onset cardiotoxicity is high but mostly subclinical. Diastolic dysfunction early after chemotherapy is a strong predictor of anthracycline cardiotoxicity.<br /><br />Copyright © 2023.

<div><h4>Association of anxiety or depression with risk of recurrent cardiovascular events and death after myocardial infarction: A nationwide registry study.</h4><i>Flygare O, Boberg J, Rück C, Hofmann R, ... Richman P, Wallert J</i><br /><b>Background</b><br />Depression and anxiety are risk factors for patients with myocardial infarction (MI). However, the association of a previous psychiatric diagnosis of anxiety or depression, or only such self-reported symptoms, with cardiovascular outcomes and mortality post-MI has not been previously examined in the same nationwide cohort.<br /><b>Methods</b><br />We linked demographic, socioeconomic and clinical data from four nationwide Swedish registries for patients enrolled in cardiac rehabilitation (CR) after first-time MI (2006-2015, N = 45,096). After multiple imputation, we applied Cox regression to estimate the post-MI outcome risk for patients with a previous psychiatric diagnosis of anxiety/depression (Diagnosis), patients with no formal diagnosis but self-reported symptoms of anxiety/depression (Symptoms), versus patients with neither Diagnosis nor Symptoms (Reference).<br /><b>Results</b><br />During one-year follow-up, fully adjusted models showed that patients with Diagnosis had a higher risk (hazard ratio [95%CI]) of all-cause mortality (1.86 [1.36, 2.53]), reinfarction (1.14 [1.06, 1.22]), their composite (1.15 [1.07, 1.23]), and an extended cardiovascular composite (1.19 [1.12, 1.26]), versus Reference, even though 77% reported no symptoms at the time of MI. In patients with Symptoms, estimates were also elevated yet somewhat attenuated compared to Reference. Findings were fairly robust across multiple sensitivity analyses.<br /><b>Conclusions</b><br />Both a previous diagnosis, and present self-reported symptoms of anxiety or depression are associated with an increased risk of death and recurrent cardiovascular events in adults with first-time MI. Only screening for present symptoms is inadequate for assessing this excessive risk. Assessment of both psychiatric history and self-reported symptoms seems warranted for these patients.<br /><br />Copyright © 2023.

<div><h4>Safety of benzodiazepines in patients with acute heart failure: A propensity score-matching study.</h4><i>Salamanca-Bautista P, Romero-Correa M, Formiga F, Antequera-Martín-Portugués I, ... Aramburu-Bodas Ó, EPICTER Investigators group</i><br /><b>Aim</b><br />Benzodiazepines (BZDs) are one of the most used drugs to control symptoms in patients with acute heart failure (HF). However, the evidence on its safety is inconclusive. The objective was to describe the characteristics of patients admitted for HF and treated with BZDs and to assess the relationship of this treatment and mortality.<br /><b>Patients and methods</b><br />We performed a cross-sectional, multicentre (74 Spanish hospitals), cohort study. Patients admitted for HF were divided depending on whether they were treated with BZDs or not. Propensity score analysis matched patients in both groups in a 1:1 manner according to different factors. The primary outcome was mortality at day 7. Secondary outcomes were mortality at days 30 and 180, as well as readmissions and emergency room visits at 180 days.<br /><b>Results</b><br />We included 1855 patients: 639 (34.4%) had prescribed BZDs treatment versus 1216 (65.6%) who had not been treated. Patients receiving BZDs had advanced heart disease, severe symptoms, need more HF intensive treatment and higher mortality. After propensity matching 381 balanced paired cases were included in each group. Treatment with BZDs was not associated with greater risk of mortality at day 7 of index hospitalization (7.6% vs 5.2%, adjusted OR 1.49, 95% CI 0.83-2.68, p = 0.186). There were also no differences between groups in terms of mortality at day 30 and 180, readmissions or visits to the emergency room.<br /><b>Conclusions</b><br />Our data support that benzodiazepines could be safely used for improving symptoms. in patients admitted for acute HF in terms of short-medium term mortality.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Incidence of stroke in patients with hypertrophic cardiomyopathy in stable sinus rhythm during long-term monitoring.</h4><i>Fumagalli C, Bonanni F, Beltrami M, Ruggieri R, ... Fumagalli S, Olivotto I</i><br /><b>Introduction</b><br />Patients with hypertrophic cardiomyopathy (HCM) are at increased risk of stroke, but the incidence and factors associated with cardioembolic events in HCM patients without atrial fibrillation (AF) remain unresolved. We determined the incidence of stroke in patients in sinus rhythm (SR) monitored with a cardiac implantable electronic device (CIED).<br /><b>Methods</b><br />All consecutive patients diagnosed with HCM and referred to CIED implantation with >16 years at diagnosis and ≥ 1 year follow-up post CIED implantation were retrospectively reviewed. Severe LA dilatation was defined as ≥48 mm. Patients were stratified by rhythm as: Pre-existing AF (AF present prior to CIED); De novo AF (AF present after CIED implantation); SR: no episodes of AF.<br /><b>Results</b><br />Of 1651 patients, 185 (11.2%) implanted with a CIED were included (57% men, age: 54 ± 17 years). Baseline, pre-existing AF was present in 73 (39%) patients. Ischemic stroke was reported in 19 (10.3%, 1.78%/year) patients and was similar across the three groups (2.3%/year vs 1.1%/year vs 0.6%/year in patients in SR vs pre-existing AF vs de novo AF, respectively, p = 0.235). In SR patients, a LAD≥48 mm posed the greatest risk of stroke (Hazard Ratio: 10.03,95% Confidence-Interval 2.79-16.01). At Cox multivariable analysis, after adjustment for oral anticoagulation, LA was independently associated with stroke while rhythm was not.<br /><b>Conclusions</b><br />in HCM patients with CIED long-term monitoring and no prior history of AF, stroke rates were similar in those with de novo AF or stable SR.

Iliceto S, Corrado D</i><br /><b>Background</b><br />Long-term data on the potential advantages of combining the third-generation subcutaneous implantable cardioverter defibrillator (S-ICD) with modern software upgrade including the \"SMART Pass\", modern programming strategies and the intermuscular (IM) two-incision implantation technique in arrhythmogenic cardiomyopathy (ACM) with different phenotypic variants are lacking. In this study we evaluated the long-term outcome of patients with ACM who underwent third-generation S-ICD (Emblem, Boston Scientific) and IM two-incision technique.<br /><b>Methods</b><br />The study population included 23 consecutive patients [70% male, median age 31 (24-46) years] diagnosed with ACM with different phenotypic variants who received third-generation S-ICD implantation with the IM two-incision technique.<br /><b>Results</b><br />During a median follow-up of 45.5 months [16-65], 4 patients (17.4%) received a at least one inappropriate shock (IS), with median annual event rate of 4.5%. Extra-cardiac oversensing (myopotential) during effort represented the only cause of IS. No IS due to T-wave oversensing (TWOS) were recorded. Only one patient (4.3%) experienced device-related complication consisting of premature cell battery depletion requiring device replacement. No device explantation because of need for anti-tachycardia pacing or ineffective therapy occurred. There was no significant difference between patients who did and did not experienced IS with regard to baseline clinical, ECG and technical characteristics. Five patients (21.7%) received appropriate shock on ventricular arrythmias.<br /><b>Conclusions</b><br />According to our finding, although the third-generation S-ICD implanted with the IM two-incision technique appears to be associated with a low risk of complications and IS due to cardiac oversensing, the risk of IS due to myopotential mainly during effort should be considered.<br /><br />Copyright © 2023.

<div><h4>Cardiometabolic index is associated with urinary albumin excretion and renal function in aged person over 60: Data from NHANES 2011-2018.</h4><i>Miao M, Deng X, Wang Z, Jiang D, ... Yu S, Yan L</i><br /><b>Purpose</b><br />Cardiometabolic index (CMI) is recently considered to have certain significance in the screening of diabetes, atherosclerosis, and renal dysfunction. Therefore, this study intends to explore the relationship between CMI and the risk of albuminuria.<br /><b>Methods</b><br />This is a cross-sectional study involving 2732 elderly people (age ≥ 60). The research data are from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018. Calculate CMI index: Triglyceride (TG) (mmol/L)/ High density lipid-cholesterol (HDLC) (mmol/L) × WHtR.<br /><b>Results</b><br />The CMI level in microalbuminuria group was significantly higher than that in normal albuminuria group (P < 0.05 or P < 0.01), whether in the general population or in diabetes and hypertensive population respectively. The proportion of abnormal microalbuminuria increased gradually with the increase of CMI tertile interval (P < 0.01). Correlation analysis showed that CMI was positively correlated with urinary albumin-creatinine ratio (UACR), blood urea nitrogen (BUN), and serum creatinine (Scr), and negatively correlated with estimated glomerular filtration rate (eGFR). With the occurrence of albuminuria as the dependent variable, weighted logistic regression analysis showed that CMI was an independent risk factor for microalbuminuria. Weighted smooth curve fitting showed that CMI index was linearly related to the risk of microalbuminuria. Subgroup analysis and interaction test showed that they participated in this positive correlation.<br /><b>Conclusions</b><br />Obviously, CMI is independently associated with microalbuminuria, suggesting that CMI, a simple indicator, can be used for risk assessment of microalbuminuria, especially in diabetes patients.<br /><br />Copyright © 2023.

<div><h4>Prevalence, management, and prediction of venous access site occlusion in patients undergoing lead revision surgery.</h4><i>Kellnar A, Fichtner S, Reitinger P, Sadoni S, ... Estner HL, Lackermair K</i><br /><b>Background</b><br />Implantable electronic cardiac devices (CIED) have emerged as an essential component in the treatment of cardiac arrhythmias and heart failure. Due to increased life expectancy, expanding indications and limited technical survival, an increasing number of revision procedures can be anticipated. Venous access site occlusion (VASO) is the main obstacle during revision surgery. In this retrospective study we evaluated the prevalence, predictive parameters and operative management of venous access site occlusion.<br /><b>Methods and results</b><br />Between 01/2016 and 12/2020 304 patients underwent lead revision surgery of transvenous CIED in our department. Prevalence of VASO was 25.7% (n = 78), one patient was symptomatic. Independent predicting clinical parameters were male sex (2.86 (1.39-5.87), p < 0.01) and lead age (1.11 (1.05-1.18), p < 0.01)). Revision surgery despite VASO was successful in 97.4% (n = 76) without prolongation of the total surgery time or higher complication rates. Yet, lead extraction was possible in 92% of patients with VASO vs. 98.2% of patients without VASO (p 0.01).<br /><b>Conclusion</b><br />VASO is a frequent condition in patients undergoing lead revision surgery, but successful revision is feasible in most cases without preceding lead extraction. However, the lower success rates of lead extractions may be prognostically relevant, especially for younger patients.<br /><br />Copyright © 2023.

<div><h4>Clinical and CMR characteristics associated with cardiac events in patients with Fabry disease.</h4><i>Hiestand R, Nowak A, Sokolska JM, Chan R, ... Manka R, Gruner C</i><br /><b>Background</b><br />The assessment of late gadolinium enhancement (LGE) and left ventricular hypertrophy (LVH) by cardiac magnetic resonance (CMR) as diagnostic and prognostic maker in Fabry disease is advancing. We aimed to investigate the impact of clinical characteristics and CMR findings on cardiac outcome in patients with FD.<br /><b>Methods</b><br />In this study 55 patients with genetically confirmed FD and available CMR imaging were included. The primary endpoint was defined as a composite of cardiac events including cardiac death, new occurrence of atrial fibrillation, heart failure, ventricular tachycardia and bradycardia requiring device insertion.<br /><b>Results</b><br />During a median follow-up of 4.9 years (IQR 3.7-5.9), 9 patients (16.3%) reached the primary cardiac end point. The global amount of LGE was associated with an increased risk for primary endpoint in the univariate analysis (HR 1.4 per 10% increase in LGE, p = 0.002). However maximal wall thickness (MWT) was the sole independent predictor of the primary endpoint in a stepwise logistic regression model (HR 9.8 per mm increase in MWT, p < 0.0001). Kaplan-Meier analysis revealed significant difference in event free survival rate between patients with and without LVH (Long-rank p = 0.006) and in patients with and without LGE (Long-rank p < 0.001). Patients without LVH and LGE were free of adverse cardiac events.<br /><b>Conclusion</b><br />LVH and LGE detected by CMR were associated with adverse cardiac events in FD.

Abstract
<div><h4>Temporal changes in incidence, treatment strategies and 1-year re-admission rates in patients with atrial fibrillation/flutter under 65 years of age: A Danish nationwide study.</h4><i>Schak L, Petersen JK, Vinding NE, Andersson C, ... Fosbøl EL, Østergaard L</i><br /><b>Aim</b><br />To examine temporal changes in incidence rates of atrial fibrillation/flutter (AF), treatment strategies, and AF readmission rates in patients <65 years.<br /><b>Methods</b><br />Using Danish nationwide registries, we identified patients <65 years with a first-time AF diagnosis from 2000 to 2018. The cohort was categorized according to calendar periods; 2000-2002, 2003-2006, 2007-2010, 2011-2014, and 2015-2018. In this retrospective cohort study the incidence rate (IR) of AF per 100,000 person years (PY), catheter ablation, electrical cardioversion, use of pharmacotherapy, and AF readmission, were investigated in the first year following AF diagnosis.<br /><b>Results</b><br />We identified 60,917 patients; 8150 (13.4%) in 2000-2002, 11,898 (19.5%) in 2003-2006, 13,560 (22.3%) in 2007-2010, 14,167 (23.3%) in 2011-2014, and 13,142 (21.6%) in 2015-2018. Apart from 2015 to 2018, a stepwise increase in the crude IR of AF was observed across calendar periods; 2000-2002: 78.7 (95% CI 77.0;80.4), 2003-2006: 86.3 (84.7;87.8), 2007-2010: 97.9 (96.3;99.6), 2011-2014: 102.3 (100.7;104.0), 2015-2018: 93.6 (92.0;95.2). Over the studied time-periods, we found a stepwise increase in the cumulative incidence of catheter ablation (1.2% to 7.6%) electrical cardioversion (2.0% to 8.7%) and treatment with oral anticoagulant therapy (OAC) (28.5% to 47.8%) within the first year of diagnosis. No temporal differences in incidence of 1-year AF readmission were identified (AF-readmissions: 2000-2002: 32.7%, 2003-2006: 31.1%, 2007-2010: 32.2%, 2011-2014: 32.1% and 2015-2018: 31.7%).<br /><b>Conclusion</b><br />The incidence rate of AF in patients <65 years increased from 2000 to 2018, as did the use of catheter ablation, electrical cardioversion and OAC in the first year following AF diagnosis. 1-year AF readmission incidence remained stable around 32% over the study period.<br /><br />Copyright © 2023.

<div><h4>Factors associated with the progression of aortic valve calcification in older adults.</h4><i>Leibowitz D, Yoshida Y, Jin Z, Nakanishi K, ... Sacco RL, Di Tullio MR</i><br /><b>Background</b><br />Aortic valve calcification (AVC) is a common valvular abnormality that predisposes to stenosis; AVC progression and factors associated with it remain unclear. We investigated the association of clinical factors and serum biomarkers with AVC progression in a population-based cohort of older adults.<br /><b>Methods</b><br />Participants enrolled in both the Cardiovascular Abnormalities and Brain Lesion study (CABL; years 2005-2010) and the Subclinical Atrial Fibrillation And Risk of Ischemic Stroke study (SAFARIS;2014-2019) represent the study cohort. AVC was defined as bright dense echoes >1 mm in size on ≥1 cusps; each cusp was graded on a scale of 0 (normal) to 3 (severe calcification) at baseline and follow up. Serum biomarkers were measured at the time of follow-up assessment.<br /><b>Results</b><br />373 participants (mean 68.1 ± 7.6 years of age, 146 M/ 227F) were included. 139 (37%) had AVC progression;93 (25%) had mild progression (1 grade), and 46 (12%) had moderate-severe progression (≥2 grades). The only significant clinical predictor of any progression was the use of anti-hypertensive medication which was associated with older age, higher BMI and more frequent hypertension, diabetes and hyperlipidemia. In multivariable analysis including biomarkers, transforming growth factor beta 1 (TGF-β1) was significantly associated with both all and moderate-severe AVC progression.<br /><b>Conclusions</b><br />A significant number of elderly subjects with AVC show progression of their valve disease; individual vascular risk factors are not associated with AVC progression, although a combined effect may exist.

<div><h4>The use of 2-D speckle tracking echocardiography in differentiating healthy adolescent athletes with right ventricular outflow tract dilation from patients with arrhythmogenic cardiomyopathy.</h4><i>Dorobantu DM, Riding N, McClean G, de la Garza MS, ... Williams C, Pieles GE</i><br /><b>Aims</b><br />Echocardiographic assessment of adolescent athletes for arrhythmogenic cardiomyopathy (ACM) can be challenging owing to right ventricular (RV) exercise-related remodelling, particularly RV outflow tract (RVOT) dilation. The aim of this study is to evaluate the role of RV 2-D speckle tracking echocardiography (STE) in comparing healthy adolescent athletes with and without RVOT dilation to patients with ACM.<br /><b>Methods and results</b><br />A total of 391 adolescent athletes, mean age 14.5 ± 1.7 years, evaluated at three sports academies between 2014 and 2019 were included, and compared to previously reported ACM patients (n = 38 definite and n = 39 borderline). Peak systolic RV free wall (RVFW-S<sub>l</sub>), global and segmental strain (S<sub>l</sub>), and corresponding strain rates (SR<sub>l</sub>) were calculated. The participants meeting the major modified Task Force Criteria (mTFC) for RVOT dilation were defined as mTFC+ (n = 58, 14.8%), and the rest as mTFC- (n = 333, 85.2%). Mean RVFW-S<sub>l</sub> was -27.6 ± 3.4% overall, -28.2 ± 4.1% in the mTFC+ group and - 27.5 ± 3.3% in the mTFC- group. mTFC+ athletes had normal RV-FW-S<sub>l</sub> when compared to definite (-29% vs -19%, p < 0.001) and borderline ACM (-29% vs -21%, p < 0.001) cohorts. In addition, all mean global and regional S<sub>l</sub> and SR<sub>l</sub> values were no worse in the mTFC+ group compared to the mTFC- (p values range < 0.0001 to 0.1, inferiority margin of 2% and 0.1 s<sup>-1</sup> respectively).<br /><b>Conclusions</b><br />In athletes with RVOT dilation meeting the major mTFC, STE evaluation of the RV can demostrate normal function and differentiate physiological remodelling from pathological changes found in ACM, improving screening in grey-area cases.<br /><br />Copyright © 2023.

<div><h4>Left ventricular morphologic progression in apical hypertrophic cardiomyopathy.</h4><i>Lee M, Shechter A, Han D, Nguyen LC, ... Rader F, Siegel RJ</i><br /><b>Background</b><br />Left ventricular (LV) morphologic progression in apical hypertrophic cardiomyopathy (AHC) has not been well studied. We evaluated serial echocardiographic changes in LV morphology.<br /><b>Methods</b><br />Serial echocardiograms in AHC patients were assessed. LV morphology was categorized according to the presence of an apical pouch or aneurysm, and LV hypertrophic severity and extent; relative, pure, and apical-mid type defined as mild (<15 mm thickness) apical hypertrophy, significant (≥15 mm) apical hypertrophy, and both apical and midventricular hypertrophy, respectively. Adverse clinical events and late gadolinium enhancement (LGE) extent on cardiac magnetic resonance were evaluated for each morphologic type.<br /><b>Results</b><br />In 41 patients, 165 echocardiograms (maximal interval: 4.2 [IQR, 2.3-11.8] years) were evaluated. Morphologic changes were observed in 19 (46%) patients. Eleven (27%) patients displayed the progression of LV hypertrophy toward pure or apical-mid type. Five (12%) and 6 (15%) patients developed new pouches and aneurysms. Patients with progression tended to be younger (50 ± 15.6 vs 59 ± 14.4 years, P = 0.058) and had a longer period of follow-up (12 [5-14] vs 3 [2-4] years, P < 0.001). During a follow-up of 7.6 (IQR 3.0-12.1) years, 21 (51%) experienced clinical events. The relative, pure, and apical-mid types showed different LGE extents (2%, 6%, and 19%, P = 0.004). Patients with severe hypertrophic and apical involvement showed higher clinical event rates.<br /><b>Conclusions</b><br />About half of AHC patients had a progression of LV morphology to more hypertrophic involvement and/or an apical pouch or aneurysm formation. Advanced AHC morphologic types were associated with higher event rates and scar burdens.<br /><br />Copyright © 2023.

Serruys PW, Soliman O</i><br /><b>Background</b><br />The balloon expandable Myval transcatheter heart valve (THV) showed encouraging results regarding residual aortic regurgitation (AR) from multiple observational studies. The newly designed Myval Octacor has been introduced recently, aiming for a reduction in AR and improved performance.<br /><b>Objectives</b><br />The focus of this study is to report the incidence of AR using the validated quantitative Videodensitometry angiography technology (qLVOT-AR%) in the first in human use of the Myval Octacor THV system.<br /><b>Methodology</b><br />We report on the first in human use of the Myval Octacor THV system in 125 patients in 18 Indian centres. Independent retrospective analysis of the final aortograms following implantation of the Myval Octacor was performed using the CAAS-A-Valve software. AR is reported as a regurgitation fraction. The previously validated cutoff values have been used to identify ≥moderate AR (RF% >17%), mild (6% < RF% ≤17%), and none or trace AR (RF% ≤ 6%).<br /><b>Results</b><br />Final aortogram was analysable for 103 patients (84.4%) among the 122 available aortograms. 64 (62%) patients, had tricuspid aortic valve (TAV), 38 (37%) with bicuspid AV (BAV), and one with unicuspid AV. The median absolute RF% was 2% [1, 6], moderate or more AR incidence was 1.9%, mild AR in 20.4%, and none or trace AR in 77.7%. The two cases with RF% >17% were in the BAV group.<br /><b>Conclusion</b><br />The initial results of Myval Octacor using quantitative angiography-derived regurgitation fraction demonstrated a favourable outcome regarding residual AR, possibly due to improved device design.

<div><h4>How common is hypertrophic cardiomyopathy… really?: Disease prevalence revisited 27 years after CARDIA.</h4><i>Massera D, Sherrid MV, Maron MS, Rowin EJ, Maron BJ</i><br /><AbstractText>Hypertrophic cardiomyopathy (HCM) is a heterogeneous albeit treatable cardiac disease of variable severity, with the potential for heart failure, atrial fibrillation and arrhythmic sudden death, characterized by otherwise unexplained left ventricular (LV) hypertrophy and affecting all ages and races. Over the last 30 years, several studies have estimated the prevalence of HCM in the general population, employing echocardiography and cardiac magnetic resonance imaging (CMR), as well electronic health records and billing databases for clinical diagnosis. The estimated prevalence in the general population based on the disease phenotype of LV hypertrophy by imaging is 1:500 (0.2%). This prevalence was initially proposed in 1995 in the population-based CARDIA study employing echocardiography, and more recently confirmed by automated CMR analysis in the large UK Biobank cohort. The 1:500 prevalence appears most relevant to clinical assessment and management of HCM. These available data suggest that HCM is not a rare condition but likely underdiagnosed clinically and by extrapolation potentially affects about 700,000 Americans and possibly 15 million people worldwide.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Non-invasive left ventricular myocardial work identifies subclinical myocardial involvement in patients with systemic lupus erythematosus.</h4><i>He W, Li J, Zhang P, Wan M, ... Liang L, Liu D</i><br /><b>Objective</b><br />Global myocardial work (MW) is a novel indicator that accounts for deformation and afterload, which may provide additional value for assessment of myocardial function. Non-invasive echocardiographic estimated left ventricular (LV) MW incorporates longitudinal strain curves and blood pressure data. This study sought to assess MW in systemic lupus erythematosus (SLE) patients with normal LV ejection fraction (LVEF) by two-dimensional speckle-tracking imaging (2D-STI) to reflect subclinical myocardial damage.<br /><b>Methods</b><br />98 SLE patients and 98 gender and age-matched healthy subjects were included. The patients with SLE were divided into mild activity (SLE disease activity index (SLEDAI) ≤ 4; n = 45), moderate activity (5 ≤ SLEDAI≤9; n = 23), and high activity (SLEDAI≥10; n = 30) subgroups. Standard transthoracic echocardiography was applied to evaluate the systolic myocardial function of the global LV. The parameters of non-invasive MW including global wasted work (GWW) and global work efficiency (GWE) were calculated from echocardiographic LV pressure-strain loops (PSL) and blood pressure at rest.<br /><b>Results</b><br />The SLE group had a significantly higher GWW (75.7 ± 39.1 mmHg% vs 37.9 ± 18.0 mmHg%, P < 0.001) and decreased GWE ratio (95.5 ± 2.0% vs 97.4 ± 1.0%, P < 0.001) compared with the controls. Among the subgroups with elevating level of disease activity, SLE patients with preserved LVEF had a significantly higher GWW (61.6 ± 29.9 mmHg% to 96.2 ± 42.2 mmHg%, P for trend = 0.001) and markedly decreased GWE (96.4 ± 1.5% to 94.4 ± 2.0%, P for trend = 0.001). In two separate multiple linear regression analyses, SLEDAI were independently associated with GWW (β = 0.271, P = 0.005) and GWE (β = -0.354, P<0.001).<br /><b>Conclusion</b><br />GWW and GWE are promising novel tools for the early detection of subclinical LV dysfunction. GWW and GWE could distinguish distinct patterns in different grades of SLEDAI.<br /><br />Copyright © 2023.

<div><h4>Association between sick sinus syndrome and atrial fibrillation: A systematic review and meta-analysis.</h4><i>Liu Y, Zheng Y, Tse G, Bazoukis G, ... Li G, Liu T</i><br /><b>Aims</b><br />Sick sinus syndrome (SSS) and atrial fibrillation (AF) frequently coexist and show a bidirectional relationship. This systematic review and meta-analysis aimed to decipher the precise relationship between SSS and AF, further exploring and comparing different therapy strategies on the occurrence or progression of AF in patients with SSS.<br /><b>Methods and results</b><br />A systematic literature search was conducted until November 2022. A total of 35 articles with 37,550 patients were included. Patients with SSS were associated with new-onset AF compared to those without SSS. Catheter ablation was associated with a lower risk of AF recurrence, AF progression, all-cause mortality, stroke and hospitalization of heart failure compared to pacemaker therapy. Regarding the different pacing strategies for SSS, VVI/VVIR has higher risk of new-onset AF than DDD/DDDR. No significant difference was found between AAI/AAIR and DDD/DDDR, as well as between DDD/DDDR and minimal ventricular pacing (MVP) for AF recurrence. AAI/AAIR was associated with higher risk of all-cause mortality when compared to DDD/DDDR, but lower risk of cardiac death when compared to DDD/DDDR. Right atrial septum pacing was associated with a similar risk of new-onset AF or AF recurrence compared to right atrial appendage pacing.<br /><b>Conclusion</b><br />SSS is associated with a higher risk of AF. For patients with both SSS and AF, catheter ablation should be considered. This meta-analysis re-emphasizes that high percentage of ventricular pacing should be avoided in patients with SSS in order to decrease AF burden and mortality.<br /><br />Copyright © 2023.

<div><h4>The importance of forward flow and venous congestion in diuretic response in acute heart failure: Insights from the ESCAPE trial.</h4><i>Eder M, Griffin M, Moreno-Villagomez J, Bellumkonda L, ... Ramos-Mastache D, Testani JM</i><br /><b>Aims</b><br />Previous studies have suggested venous congestion as a stronger mediator of negative cardio-renal interactions than low cardiac output, with neither factor having a dominant role. While the influence of these parameters on glomerular filtration have been described, the impact on diuretic responsiveness is unclear. The goal of this analysis was to understand the hemodynamic correlates of diuretic response in hospitalized patients with heart failure.<br /><b>Methods and results</b><br />We analyzed patients from the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) dataset. Diuretic efficiency (DE) was defined as the average daily net fluid output per doubling of the peak loop diuretic dose. We evaluated a pulmonary artery catheter hemodynamic-guided cohort (n = 190) and a transthoracic echocardiogram (TTE) cohort (n = 324) where DE was evaluated with hemodynamic and TTE parameters. Metrics of \"forward flow\" such as cardiac index, mean arterial pressure and left ventricular ejection fraction were not associated with DE (p > 0.2 for all). Worse baseline venous congestion was paradoxically associated with better DE as assessed by right atrial pressure (RAP), right atrial area (RAA), and right ventricular systolic and diastolic area (p < 0.05 for all). Renal perfusion pressure (capturing both congestion and forward flow) was not associated with diuretic response (p = 0.84).<br /><b>Conclusions</b><br />Worse venous congestion was weakly associated with better loop diuretic response. Metrics of \"forward flow\" did not demonstrate any correlation with diuretic response. These observations raise questions about the concept of central hemodynamic perturbations as the primary drivers of diuretic resistance on a population level in HF.<br /><br />Copyright © 2023.

Adult patients ≥18 years with a IHCA where resuscitation was initiated were included. Uni- and multivariable logistic regression was used to investigate associations between temporal factors and survival to 30 days.<br /><b>Results</b><br />30-day survival and Return of Spontaneous Circulation (ROSC) was 36.8% and 67.9% following CA during the day and decreased during the evening (32.0% and 66.3%) and night (26.2% and 60.2%) (p < 0.001 and p = 0.028). When comparing the survival rates between the day and the night, survival decreased more (change in relative survival rates) in small (<99 beds) compared to large (<400) hospitals (35.9% vs 25%), in non-academic vs academic hospitals (33.5% vs 22%) and on non-Electro Cardiogram (ECG)-monitored wards vs ECG-monitored wards (46.2% vs 20.9%) (p < 0.001 for all).

We compared the diagnostic efficacy of these criteria, which remain controversial.<br /><b>Methods</b><br />Following resting right heart catheterization (RHC), all patients underwent exercise RHC (eRHC). The patients were divided into different ePH and non-exercise pulmonary hypertension (nPH) groups according to the above criteria. Joint criteria were used as the reference to compare the other two, namely diagnostic concordance, sensitivity and specificity. We conducted further analysis to determine the correlation between different diagnostic criteria grouping and the clinical severity of PH.<br /><b>Results</b><br />Thirty-three patients with mPAP<sub>rest</sub> ≤ 20 mmHg were enrolled. a) Diagnostic concordance, sensitivity and specificity: compared with Joint criteria, the diagnostic concordances of Two-point criteria and Multi-point criteria were 78.8% (κ = 0.570, P < 0.01) and 90.9% (κ = 0.818, P < 0.01), respectively; the sensitivity of Two-point criteria was high (100%), but the specificity was poor (56.3%); however, Multi-point criteria exhibited higher sensitivity (94.1%) and specificity (87.5%). b) Clinically relevant analysis: a significant difference was observed in several clinical severity indicators between ePH and nPH patients according to Multi-point criteria grouping(all P < 0.05).<br /><b>Conclusion</b><br />Multi-point criteria are more clinically relevant and provide better diagnostic efficiency.<br /><br />Copyright © 2023.

<div><h4>Potential roles of microRNAs and long noncoding RNAs as diagnostic, prognostic and therapeutic biomarkers in coronary artery disease.</h4><i>Jiang Y, Zhao Y, Li ZY, Chen S, Fang F, Cai JH</i><br /><AbstractText>Coronary artery disease (CAD), which is mainly caused by atherosclerotic processes in coronary arteries, became a significant health issue. MicroRNAs (miRNAs), and long noncoding RNAs (lncRNAs), have been shown to be stable in plasma and could thereby be adopted as biomarkers for CAD diagnosis and treatment. MiRNAs can regulate CAD development through different pathways and mechanisms, including modulation of vascular smooth muscle cell (VSMC) activity, inflammatory responses, myocardial injury, angiogenesis, and leukocyte adhesion. Similarly, previously studies have indicated that the causal effects of lncRNAs in CAD pathogenesis and their utility in CAD diagnosis and treatment, has been found to lead to cell cycle transition, proliferation dysregulation, and migration in favour of CAD development. Differential expression of miRNAs and lncRNAs in CAD patients has been identified and served as diagnostic, prognostic and therapeutic biomarkers for the assessment of CAD patients. Thus, in the current review, we summarize the functions of miRNAs and lncRNAs, which aimed to identify novel targets for the CAD diagnosis, prognosis, and treatment.</AbstractText><br /><br />Copyright © 2023.

Gore & Associates, Flagstaff, Ariz) and Valiant Captivia thoracic stent graft (Medtronic Inc., Santa Rosa, CA) for acute type B aortic dissection (TBAD).<br /><b>Methods</b><br />The early and mid-term outcomes were analyzed for 413 patients undergoing TEVAR using conformable TAG thoracic endoprosthesis and Valiant Captivia thoracic stent graft for acute TBAD. 100 propensity-matched pairs of patients were generated, including 100 patients in the CTAG group and 200 patients in the Valiant Captivia group.<br /><b>Results</b><br />Operative mortality were 2.33% (3 of 129) in the CTAG group and 1.76% (5 of 284) in the Valiant Captivia group. The median follow-up was 41.67 (26.00-60.67) months. No significant difference in mortality (9 [7.00%] vs. 36 [12.68%], P = 0.95) or re-intervention rate (3 [2.33%] vs. 20 [7.04%], P = 0.29) was observed between two groups. CTAG group have a lower incidence rate of distal stent graft-induced new entry tear than Valiant Captivia group (2.33% vs. 9.86%, P = 0.045). Lower incidence of type Ia endoleak was identified in the CTAG group (2.22%) than the Valiant Captivia group (14.41%) in patients with type III arch (P = 0.039).<br /><b>Conclusions</b><br />Both Valiant Captivia thoracic stent graft and CTAG thoracic endoprosthesis can be safely performed for acute TBAD with low operative mortality, favorable mid-term survival and freedom from reintervention. CTAG thoracic endoprosthesis had fewer dSINE even with larger oversizing and potentially suitable for type III arch with fewer type Ia endoleaks.<br /><br />Copyright © 2023.

Abstract
<div><h4>Long-term outcomes of valve-sparing root versus composite valve graft replacement for acute type A aortic dissection: Meta-analysis of reconstructed time-to-event data.</h4><i>Sá MP, Tasoudis P, Jacquemyn X, Van den Eynde J, ... Serna-Gallegos D, Sultan I</i><br /><b>Objectives</b><br />To evaluate the long-term outcomes of valve-sparing aortic root replacement (VSARR) versus composite aortic valve graft replacement (CAVGR) in the treatment of acute type A aortic dissections (ATAAD).<br /><b>Methods</b><br />We performed a pooled meta-analysis of Kaplan-Meier-derived time-to-event data from studies with longer follow-up beyond the immediate postoperative period.<br /><b>Results</b><br />Seven studies met our eligibility criteria, comprising a total of 858 patients (367 patients in the VSARR groups and 491 patients in the CAVGR group). We found no statistically significant differences in the overall survival between the groups over time (HR 0.83, 95%CI 0.63-1.10, P = 0.192), but we observed a higher risk of reoperation in the VSARR group when compared with the CAVGR group (HR 9.99, 95% CI 2.23-44.73, P = 0.003). The meta-regression revealed statistically significant positive coefficients for age (P < 0.001) in the analysis of survival, which means that this covariate has a modulating effect on this outcome. The higher the mean age, the higher the HR for overall mortality was found to be with VSARR as compared with CAVGR. Other covariates such as female sex, hypertension, diabetes, connective tissue disorders, bicuspid aortic valve, hemiarch and/or total arch replacement, concomitant coronary bypass surgery did not seem to have any effect on the outcomes.<br /><b>Conclusion</b><br />VSARR did not confer a better (or worse) survival over time in patients with ATAAD, but it was associated with higher risk of reoperations in the long run.<br /><br />Copyright © 2023.

Abstract
<div><h4>Prevalence of transthyretin-related amyloidosis in Tuscany: Data from the regional population-based registry.</h4><i>Cappelli F, Del Franco A, Vergaro G, Mazzoni C, ... Emdin M, Perfetto F</i><br /><AbstractText>The limited available data regarding the prevalence of transthyretin amyloidosis, both for wild-type (ATTRwt) and hereditary form (ATTRv), is inferred from highly selected patients and subsequent extrapolations that limit the comprehension of the clinical disease impact. The Tuscan healthcare system in 2006 developed a web-based rare disease registry, to monitor and profile patients affected by rare diseases. Clinicians belonging to regional validated healthcare data centres can register patients at the diagnosis, with a rigorous approach and distinguishing the types of amyloidosis, i.e., ATTRwt versus ATTRv. Thanks to this data collection method, available from July 2006 and extended with electronic therapy plans related to a diagnosis since May 2017, we analysed prevalence and incidence of ATTR and its subtypes. On November 30th 2022, ATTRwt prevalence in Tuscany is 90.3 per 1,000,000 persons and ATTRv prevalence is 9.5 per 1,000,000 persons, whereas the annual incidence ranges from 14.4 to 26.7 per 1,000,000 persons and from 0.8 to 2.7 per 1,000,000 persons, respectively. The male gender is predominant in both forms. All except one patient showed evidence of cardiomyopathy. This epidemiological data requires attention, not only to increase the effort for the clinical management and earlier diagnosis, but also to underline the need for the disease-specific treatments.</AbstractText><br /><br />Copyright © 2023.
