<div><h4>C-Reactive Protein and Risk of Cardiovascular Events and Mortality in Patients with Various Cardiovascular Disease Locations.</h4><i>Burger PM, Pradhan AD, Dorresteijn JAN, Koudstaal S, ... Visseren FLJ, Utrecht Cardiovascular Cohort-Second Manifestations of ARTerial disease study group</i><br /><AbstractText>Anti-inflammatory drugs reduce the risk of cardiovascular events in patients with coronary artery disease (CAD), but less is known about the relation between inflammation and outcomes in patients with cerebrovascular disease (CeVD), peripheral artery disease (PAD), and abdominal aortic aneurysm (AAA). This study assessed the association between C-reactive protein (CRP) and clinical outcomes in patients with CAD (n = 4,517), CeVD (n = 2,154), PAD (n = 1,154), and AAA (n = 424) from the prospective Utrecht Cardiovascular Cohort-Second Manifestations of ARTerial disease study. The primary outcome was recurrent cardiovascular disease (CVD), defined as myocardial infarction, ischemic stroke, or cardiovascular death. Secondary outcomes were major adverse limb events and all-cause mortality. Associations between baseline CRP and outcomes were assessed using Cox proportional hazards models adjusted for age, sex, smoking, diabetes mellitus, body mass index, systolic blood pressure, non-high-density lipoprotein cholesterol, and glomerular filtration rate. Results were stratified by CVD location. During a median follow-up of 9.5 years, 1,877 recurrent CVD events, 887 major adverse limb events, and 2,341 deaths were observed. CRP was independently associated with recurrent CVD (hazard ratio [HR] per 1 mg/L 1.08, 95% confidence interval [CI] 1.05 to 1.10), and all secondary outcomes. Compared with the first quintile of CRP, HRs for recurrent CVD were 1.60 (95% CI 1.35 to 1.89) for the last quintile ≤10 mg/L and 1.90 (95% CI 1.58 to 2.29) for the subgroup with CRP >10 mg/L. CRP was associated with recurrent CVD in patients with CAD (HR per 1 mg/L 1.08, 95% CI 1.04 to 1.11), CeVD (HR 1.05, 95% CI 1.01 to 1.10), PAD (HR 1.08, 95% CI 1.03 to 1.13), and AAA (HR 1.08, 95% CI 1.01 to 1.15). The association between CRP and all-cause mortality was stronger for patients with CAD (HR 1.13, 95% CI 1.09 to 1.16) than for patients with other CVD locations (HRs 1.06 to 1.08; p = 0.002). Associations remained consistent beyond 15 years after the CRP measurement. In conclusion, greater CRP is independently associated with an increased risk of recurrent CVD and mortality, irrespective of previous CVD location.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Cardiovascular Health by Life\'s Essential 8 and Associations With Coronary Artery Calcium in South Asian American Adults in the MASALA Study.</h4><i>Shah NS, Talegawkar SA, Jin Y, Hussain BM, Kandula NR, Kanaya AM</i><br /><AbstractText>South Asian Americans experience high cardiovascular disease risk. We evaluated the distribution and correlates of cardiovascular health (CVH) summarized by the Life\'s Essential 8 (LE8) score among South Asian adults. In participants of the MASALA (Mediators of Atherosclerosis in South Asians Living in America) study, the association of demographic, social, and cultural factors with LE8 score was evaluated with t tests and analysis of variance. The association of LE8 score with coronary artery calcium (CAC) was evaluated with adjusted logistic regression. There were 556 women (mean age 55.9 years [SD 8.7], mean LE8 score 67.2 (SD 12.6) and 608 men (mean age 57.5 years [SD 9.9], mean LE8 score 61.9 (SD 13.1). Among women and men, the LE8 CVH score was higher in participants with higher annual family income, higher educational attainment, and fewer depressive symptoms. Overall, there was 26% lower odds of any CAC for each 10-point higher LE8 score (odds ratios [OR] 0.74, 95% confidence intervals [CI] 0.66 to 0.83), with similar magnitude of association in women and men. Participants with a high LE8 CVH score had 82% lower odds of CAC (OR 0.18, 95% CI 0.09 to 0.33), and participants with an intermediate LE8 CVH score had 38% lower odds of CAC (OR 0.62, 95% CI 0.41 to 0.94) than did participants with a low LE8 CVH score, with similar findings stratified by gender. In conclusion, in this cohort of South Asian Americans, most adults had suboptimal CVH assessed by the LE8 score. Higher LE8 score correlated with lower odds of any CAC.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Long-Term Outcomes of Patients With Carotid and Aortic Body Tumors.</h4><i>Verghis NM, Brown JA, Yousef S, Aranda-Michel E, ... Singh M, Sultan I</i><br /><AbstractText>Chemodectomas are tumors derived from parasympathetic nonchromaffin cells and are often found in the aortic and carotid bodies. They are generally benign but can cause mass-effect symptoms and have local or distant spread. Surgical excision has been the main curative treatment strategy. The National Cancer Database was reviewed to study all patients with carotid or aortic body tumors from 2004 to 2015. Demographic data, tumor characteristics, treatment strategies, and patient outcomes were examined, split by tumor location. Kaplan-Meier survival estimates were generated for both locations. In total, 248 patients were examined, with 151 having a tumor in the carotid body and 97 having a tumor in the aortic body. Many variables were similar between both tumor locations. However, aortic body tumors were larger than those in the carotid body (477.80 ± 477.58 mm vs 320.64 ± 436.53 mm, p = 0.008). More regional lymph nodes were positive in aortic body tumors (65.52 ± 45.73 vs 35.46 ± 46.44, p <0.001). There were more distant metastases at the time of diagnosis in carotid body tumors (p = 0.003). Chemotherapy was used more for aortic body tumors (p = 0.001); surgery was used more for carotid body tumors (p <0.001). There are slight differences in tumor characteristics and response to treatment. Surgical resection is the cornerstone of management, and radiation can often be considered. In conclusion, chemodectomas are generally benign but can present with metastasis and compressive symptoms that make understanding their physiology and treatment important.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Outcomes of Transcatheter Aortic Valve Implantation in Nonagenarians and Octogenarians (Analysis from the National Inpatient Sample Database).</h4><i>Ismayl M, Aboud Abbasi M, Al-Abcha A, Robertson S, ... Guerrero M, Anavekar NS</i><br /><AbstractText>Risks among nonagenarian (age ≥90 years) and octogenarian (age 80 to 89 years) patients who underwent transcatheter aortic valve implantation (TAVI) compared with clinically similar septuagenarian (age 70 to 79 years) patients remain unclear. This study aimed to assess the outcomes of TAVI in nonagenarians and octogenarians compared with septuagenarians. We conducted a retrospective cohort study using the National Inpatient Sample database to identify patients aged ≥70 years hospitalized for TAVI from 2016 to 2020 and to compare outcomes in nonagenarians and octogenarians versus septuagenarians. The primary outcome was in-hospital mortality. Secondary outcomes included procedural complications, length of stay (LOS), and total costs. The trends in in-hospital outcomes were evaluated. Results were adjusted for demographic/clinical factors. The total cohort included 263,325 patients hospitalized for TAVI, of whom 11.9% were nonagenarians, 51.1% octogenarians, and 37.0% septuagenarians. After adjustment, nonagenarians and octogenarians had higher odds of in-hospital mortality (adjusted odds ratio 1.80, 95% confidence interval 1.34 to 2.41 for nonagenarians; adjusted odds ratio 1.65, 95% confidence interval 1.35 to 2.01 for octogenarians), heart block, permanent pacemaker insertion, stroke, major bleeding, blood transfusion, and palliative care consultation than septuagenarians (all p <0.01). LOS was longer and the total costs were higher for nonagenarians and octogenarians (both p <0.01). Over the study period, in-hospital mortality decreased in nonagenarians (p<sub>trend</sub> = 0.04), and major bleeding, permanent pacemaker insertion, LOS, and costs decreased in all patients aged ≥70 years (p<sub>trend</sub> <0.01). In conclusion, nonagenarians and octogenarians who underwent TAVI have higher rates of mortality and procedure-related complications than clinically similar septuagenarians. Further research is necessary to optimize outcomes in this frail population.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Prognostic Value of 6-Minute Walk Test in Advanced Heart Failure With Reduced Ejection Fraction.</h4><i>Scrutinio D, Guida P, Passantino A</i><br /><AbstractText>There is limited evidence regarding the prognostic value of the 6-minute walk test for patients with advanced heart failure (HF). Accordingly, we studied 260 patients presenting to inpatient cardiac rehabilitation (CR) with advanced HF. The primary outcome was 3-year all-cause mortality after discharge from CR. The association between 6-minute walk distance (6MWD) and the primary outcome was determined using the multivariable Cox regression analysis. To avoid collinearity, 6MWD at admission (6MWD<sub>adm</sub>) to CR and 6MWD at discharge (6MWD<sub>disch</sub>) from CR were analyzed separately. At multivariable analysis, 4 baseline characteristics (age, ejection fraction, systolic blood pressure, and blood urea nitrogen) were identified as prognostic of the primary outcome (baseline risk model). After adjusting for the baseline risk model, the hazard ratios of 6MWD<sub>adm</sub> and 6MWD<sub>disch</sub> modeled as per 50-m increase for the primary outcome were 0.92 (95% confidence interval [CI] 0.85 to 0.99, p = 0.035) and 0.93 (95% CI 0.88 to 0.99, p = -017), respectively. After adjusting for the Meta-analysis Global Group in Chronic Heart Failure (MAGGIC) score, the corresponding hazard ratios were 0.91 (95% CI 0.84 to 0.98, p = 0.017) and 0.93 (95% CI 0.88 to 0.99, p = 0.016). The addition of either 6MWD<sub>adm</sub> or 6MWD<sub>disch</sub> to the baseline risk model or the MAGGIC score yielded a statistically significant increase in global chi-square and in the net proportion of survivors reclassified downward. In conclusion, our data suggest that the distance covered during a 6-minute walk test predicts survival and provides incremental prognostic information on the top of well-established prognostic factors and the MAGGIC risk score in advanced HF.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Pulmonary Capillary Recruitment Is Attenuated Post Left Ventricular Assist Device Implantation.</h4><i>Kim CH, Sajgalik P, Schettle SD, Clavell AL, ... Taylor BJ, Johnson BD</i><br /><AbstractText>There is limited knowledge of pulmonary physiology and pulmonary function after continuous flow-left ventricular assist device (CF-LVAD) implantation. Therefore, this study investigated whether CF-LVAD influenced pulmonary circulation by assessing pulmonary capillary blood volume and alveolar-capillary conductance in addition to pulmonary function in patients with heart failure. Seventeen patients with severe heart failure who were scheduled for CF-LVAD implantation (HeartMate II, III, Abbott, Abbott Park, IL or Heart Ware, Medtronic, Minneapolis, MN) participated in the study. They underwent pulmonary function testing (measures of lung volumes and flow rates) and unique measures of pulmonary physiology using a rebreathe technique that quantified the diffusing capacity of the lungs for carbon monoxide (DLCO) and diffusing capacity of the lungs for nitric oxide before and 3 months after CF-LVAD implantation. After CF-LVAD, pulmonary function was not significantly changed (p >0.05). For lung diffusing capacity, alveolar volume (VA) was not changed (p = 0.47), but DLCO was significantly reduced (p = 0.04). After correcting for VA, DLCO/VA showed a trend toward reduction (p = 0.08). For the alveolar-capillary component, capillary blood volume (Vc) was significantly reduced (p = 0.04), and alveolar-capillary membrane conductance trended toward a reduction (p = 0.06). However, alveolar-capillary membrane conductance/Vc was not altered (p = 0.92). In conclusion, soon after CF-LVAD implantation, Vc is reduced likely because of pulmonary capillary derecruitment, which contributes to the decrease in lung diffusing capacity.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Effects of Long-Term Carvedilol Therapy in Patients With ST-Segment Elevation Myocardial Infarction and Mildly Reduced Left Ventricular Ejection Fraction.</h4><i>Amano M, Izumi C, Watanabe H, Ozasa N, ... Kimura T, CAPITAL-RCT Investigators</i><br /><AbstractText>The benefits of long-term oral β-blocker therapy in patients with ST-segment elevation myocardial infarction (STEMI) with mildly reduced left ventricular ejection fraction (LVEF; ≥40%) are still unknown. We sought to evaluate the efficacy of β-blocker therapy in patients with STEMI with mildly reduced LVEF. In the CAPITAL-RCT (Carvedilol Post-Intervention Long-Term Administration in Large-Scale Randomized Controlled Trial), patients with STEMI with successful percutaneous coronary intervention with an LVEF of ≥40% were randomly assigned to carvedilol or no β-blocker therapy. Among 794 patients, 280 patients had an LVEF of <55% at baseline (mildly reduced LVEF stratum), whereas 514 patients had an LVEF of ≥55% at baseline (normal LVEF stratum). The primary end point was a composite of all-cause death, myocardial infarction, hospitalization for acute coronary syndrome, and hospitalization for heart failure, and the secondary end point was a cardiac composite outcome: a composite of cardiac death, myocardial infarction, and hospitalization for heart failure. The median follow-up period was 3.7 years. The lower risk of carvedilol therapy relative to no β-blocker therapy was not significant for the primary end point in either the mildly reduced or normal LVEF strata. However, it was significant for the cardiac composite end point in the mildly reduced LVEF stratum (0.82/100 person-years vs 2.59/100 person-years, hazard ratio 0.32 [0.10 to 0.99], p = 0.047) but not in the normal LVEF stratum (1.48/100 person-years vs 1.06/100 person-years, hazard ratio 1.39 [0.62 to 3.13], p = 0.43, p for interaction = 0.04). In conclusion, long-term carvedilol therapy in patients with STEMI with primary percutaneous coronary intervention might be beneficial for preventing cardiac-related events in those with a mildly reduced LVEF.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Significance of Anteroseptal Late Gadolinium Enhancement Among Patients With Acute Myocarditis.</h4><i>Mulla W, Segev A, Novak A, Yogev D, ... Beigel R, Younis A</i><br /><AbstractText>Anteroseptal location of late gadolinium enhancement (LGE) in patients with acute myocarditis (AM) detected by cardiovascular magnetic resonance may indicate an independent marker of unfavorable outcomes according to recent data. We aimed to evaluate the clinical characteristics, management, and inhospital outcomes in patients with AM with positive LGE based on its presence in the anteroseptal location. We analyzed data from 262 consecutive patients hospitalized with a diagnosis of AM with positive LGE within 5 days of hospitalization (n = 425). Patients were divided into 2 groups: those with anteroseptal LGE (n = 25, 9.5%) and those with non-anteroseptal LGE (n = 237, 90.5%). Except for age that was higher in patients with anteroseptal LGE, the demographic and clinical characteristics did not differ significantly between both groups including past medical history, clinical presentation, electrocardiogram parameters, and lab values. Moreover, patients with anteroseptal LGE were more likely to present with reduced left ventricular ejection fraction and to receive congestive heart failure treatments. Although univariate analysis showed that patients with anteroseptal LGE were more likely to have inhospital major adverse cardiac events (28% vs 9%, p = 0.003), there was no difference inhospital outcomes on multivariable analysis between both groups (hazard ratio, 1.17 [95% confidence interval, 0.32 to 4.22], p = 0.81). A higher left ventricular ejection fraction in either echocardiography or cardiovascular magnetic resonance corresponded to better inhospital outcomes regardless of the presence or absence of anteroseptal LGE. In conclusion, the presence of anteroseptal LGE did not confer additional prognostic value for inhospital outcomes.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Implications of the Mitral Leaflet Coaptation Pattern on Clinical Outcomes in Patients With Functional Mitral Regurgitation.</h4><i>Kim H, Kim IC, Lee S</i><br /><AbstractText>The classification of secondary mitral regurgitation (MR) is based on atrial functional MR (AFMR) or ventricular functional MR (VFMR) and volume changes, but the mitral leaflet coaptation angle also contributes to the MR mechanism. The clinical implications of the coaptation angle on cardiovascular (CV) outcomes have not been well evaluated. A total of 469 consecutive patients (265 AFMR vs 204 VFMR) with more than moderate MR were evaluated for the occurrence of heart failure, mitral valve operations, and CV death. The coaptation angle was assessed by measuring the internal angle between both leaflets at mid-systole using the apical 3-chamber view. A coaptation angle ≥130° was classified as leaflet flattening, and an angle <130° was classified as leaflet tethering. AFMR and VFMR were associated with higher frequencies of leaflet flattening and tethering, respectively. AFMR was more likely to be associated with older age, atrial fibrillation, and preserved ejection fraction, all of which were related to leaflet flattening. During a follow-up of 2.3 years, 83 patients had heart failure (17.7%), 21 patients underwent mitral valve operations (4.5%), and 34 patients died (7%). Compared with leaflet tethering, leaflet flattening was more significantly related to CV events, whereas CV event rates were less markedly different in A/VFMR. Irrespective of A/VFMR, leaflet flattening and atrial fibrillation were associated with a higher frequency of CV events. Adjusted analysis showed that leaflet flattening remained an independent predictor of CV events (hazard ratio 3.5, 95% confidence interval 1.11 to 4.88, p = 0.003), whereas A/VFMR did not. In conclusion, the leaflet coaptation angle in patients with functional MR could provide risk stratification superior to that of A/VFMR. Leaflet flattening appears to be associated with unfavorable clinical outcomes.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Eligibility to Intensified Antithrombotic Regimens for Secondary Prevention in Patients Who Underwent Percutaneous Coronary Intervention.</h4><i>Greco A, Scilletta S, Faro DC, Agnello F, ... Imbesi A, Capodanno D</i><br /><AbstractText>Single antiplatelet therapy (SAPT) and intensified antithrombotic regimens (prolonged dual antiplatelet therapy [DAPT] or dual pathway inhibition [DPI]) are recommended for secondary prevention in patients who underwent percutaneous coronary intervention (PCI) after initial DAPT. We aimed to characterize eligibility to such strategies and to explore to what extent guidelines are applied in clinical practice. Patients who underwent PCI for acute or chronic coronary syndrome who completed initial DAPT were analyzed from a prospective registry. Patients were categorized into SAPT, prolonged DAPT/DPI, or DPI groups as per guideline indication by using a risk stratification algorithm. Predictors of receiving intensified regimens and the divergency of practice from guidelines were investigated. Between October 2019 and September 2021, a total of 819 patients were included. Based on the guidelines, 83.7% of patients qualified for SAPT, 9.6% for any intensified regimen (i.e., prolonged DAPT or DPI), and 6.7% for DPI only. At multivariable analysis, patients were more likely to receive an intensified regimen if they had diabetes, dyslipidemia, peripheral artery disease, multivessel disease, or previous myocardial infarction. Conversely, they were less likely to receive an intensified regimen if they had atrial fibrillation, chronic kidney disease, or previous stroke. Guidelines were not followed in 18.3% of cases. In particular, only 14.3% of candidates to intensified regimens were treated accordingly. In conclusion, although the majority of patients who underwent PCI after the initial period of DAPT were eligible for SAPT, 1 out of 6 had an indication to intensified regimens. However, such intensified regimens were underused among eligible patients.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Pericardial Fluid Analysis in Diagnosis and Prognosis of Patients Who Underwent Pericardiocentesis.</h4><i>Sullivan A, Dennis ASC, Rathod K, Jones D, ... Thornton CC, O\'Mahony C</i><br /><AbstractText>In this study, we aimed to examine the diagnostic yield of pericardial fluid biochemistry and cytology and their prognostic significance in patients with percutaneously drained pericardial effusions, with and without malignancy. This is a single-center, retrospective study of patients who underwent pericardiocentesis between 2010 and 2020. Data were extracted from electronic patient records, including procedural information, underlying diagnosis, and laboratory results. Patients were grouped into those with and without underlying malignancy. A Cox proportional hazards model was used to analyze the association of variables with mortality. The study included 179 patients; 50% had an underlying malignancy. There were no significant differences in pericardial fluid protein and lactate dehydrogenase between the 2 groups. Diagnostic yield from pericardial fluid analysis was greater in the malignant group (32% vs 11%, p = 0.002); 72% of newly diagnosed malignancies had positive fluid cytology. The 1-year survival was 86% and 33% in nonmalignant and malignant groups, respectively (p <0.001). Of 17 patients who died within the nonmalignant group, idiopathic effusions were the largest group (n = 6). In malignancy, lower pericardial fluid protein and higher serum C-reactive protein were associated with increased risk of mortality. In conclusion, pericardial fluid biochemistry has limited value in determining the etiology of pericardial effusions; fluid cytology is the most important diagnostic test. Mortality in malignant pericardial effusions may be associated with lower pericardial fluid protein levels and a higher serum C-reactive protein. Nonmalignant pericardial effusions do not have a benign prognosis and close follow-up is required.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Reproducibility of Femoropopliteal Artery Intravascular Ultrasound Imaging in Patients With Peripheral Artery Disease.</h4><i>Soney H, Kakkilaya A, Vazquez DF, Banerjee R, ... Tsai S, Banerjee S</i><br /><AbstractText>Despite increased use of intravascular ultrasound (IVUS) during peripheral artery interventions, evidence for reproducibility of IVUS measurements and its relation to angiography is lacking. Forty cross-sectional IVUS images of the femoropopliteal artery from 20 randomly selected patients enrolled in the XLPAD (Excellence in Peripheral Artery Disease) registry who underwent peripheral artery interventions and met criteria based on IVUS consensus guidelines were independently assessed by 2 blinded readers. IVUS images from 6 patients (40 images) were selected for angiographic correlation and met criteria for identifiable landmarks (e.g., stent edge and bifurcation). Lumen cross-sectional area (CSA), external elastic membrane (EEM) CSA, luminal diameter, and reference vessel diameter were repeatedly measured. The Lumen CSA and EEM CSA intra-observer agreement by Spearman rank-order correlation (ρ) was >0.993, intraclass correlation coefficient was >0.997, and repeatability coefficient was <1.34. For the interobserver measurement of luminal CSA and EEM CSA, the ρ = 0.742 and 0.764; intraclass correlation coefficient = 0.888 and 0.885; and repeatability coefficient = 7.24 and 11.34, respectively. A Bland-Altman plot for lumen and EEM CSA showed good reproducibility. For angiographic comparison, the ρ for luminal diameter, luminal area, and vessel area were 0.419, 0.414, and 0.649, respectively. Femoropopliteal IVUS measurements showed strong intra-observer and interobserver agreement; IVUS and angiographic measurements did not demonstrate a similar strong agreement.</AbstractText><br /><br />Copyright © 2023 The Authors.

<div><h4>Machine Learning-Based Prediction of Atrial Fibrillation Risk Using Electronic Medical Records in Older Aged Patients.</h4><i>Kao YT, Huang CY, Fang YA, Liu JC, Chang TH</i><br /><AbstractText>Atrial fibrillation (AF) is an independent risk factor that increases the risk of stroke 5-fold. The purpose of our study was to develop a 1-year new-onset AF predictive model by machine learning based on 3-year medical information without electrocardiograms in our database to identify AF risk in older aged patients. We developed the predictive model according to the Taipei Medical University clinical research database electronic medical records, including diagnostic codes, medications, and laboratory data. Decision tree, support vector machine, logistic regression, and random forest algorithms were chosen for the analysis. A total of 2,138 participants (1,028 women [48.1%]; mean [standard deviation] age 78.8 [6.8] years) with AF and 8,552 random controls (after the matching process) without AF (4,112 women [48.1%]; mean [standard deviation] age 78.8 [6.8] years) were included in the model. The 1-year new-onset AF risk prediction model based on the random forest algorithm using medication and diagnostic information, along with specific laboratory data, attained an area under the receiver operating characteristic of 0.74, whereas the specificity was 98.7%. Machine learning-based model focusing on the older aged patients could offer acceptable discrimination in differentiating the risk of incident AF in the next year. In conclusion, a targeted screening approach using multidimensional informatics in the electronic medical records could result in a clinical choice with efficacy for prediction of the incident AF risk in older aged patients.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Medical Costs of Chronic Kidney Disease and Type 2 Diabetes Among Newly Diagnosed Heart Failure Patients With Reduced, Mildly Reduced, and Preserved Ejection Fraction.</h4><i>Nichols GA, Qiao Q, Linden S, Kraus BJ</i><br /><AbstractText>The economic burden of heart failure (HF) is enormous, but studies of HF costs typically consider the disease to be a single entity. We sought to distinguish the medical costs for patients with HF with reduced ejection fraction (HFrEF), mildly reduced ejection fraction (HFmrEF), and HF with preserved ejection fraction (HFpEF). We identified 16,516 adult patients with an incident HF diagnosis and an echocardiogram from 2005 to 2017 in the electronic medical record of Kaiser Permanente Northwest. Using the echocardiogram nearest to the first diagnosis date, we classified patients with HFrEF (ejection fraction [EF] ≤40%), HFmrEF (EF 41% to 49%), or HFpEF (EF ≥50%). We calculated annualized inpatient, outpatient, emergency, pharmaceutical medical utilization and costs and total costs in $2,020, adjusted for age and gender using generalized linear models, with further analysis of the effects of co-morbid chronic kidney disease (CKD) and type 2 diabetes (T2D). For all HF types, 1 in 5 patients were affected by both CKD and T2D, and costs were significantly higher when both co-morbidities were present. Total per-person costs were significantly higher for HFpEF ($33,740, 95% confidence interval $32,944 to $34,536) than HFrEF ($27,669, $25,649 to $29,689) or HFmrEF ($29,484, $27,166 to $31,800), driven by in- and outpatient visits. Across HF types, visits approximately doubled with the presence of both co-morbidities. Due to greater prevalence, HFpEF accounted for the majority of total and resource-specific treatment costs of HF, regardless of the presence of CKD and/or T2D. In summary, the economic burden was greater per HFpEF patient and was further amplified by co-morbid CKD and T2D. HFpEF accounted for the large majority of total HF costs, underscoring the need to implement effective treatments.</AbstractText><br /><br />Copyright © 2023 The Authors. Published by Elsevier Inc.

<div><h4>Prevalence and Impact of Poorly Controlled Modifiable Risk Factors Among Patients Who Underwent Atrial Fibrillation Ablation.</h4><i>Stout K, Almerstani M, Adomako R, Shin D, ... Peeraphatdit T, Naksuk N</i><br /><AbstractText>Managing atrial fibrillation (AF) risk factors (RFs) improves ablation outcomes in obese patients. However, real-world data, including nonobese patients, are limited. This study examined the modifiable RFs of consecutive patients who underwent AF ablation at a tertiary care hospital from 2012 to 2019. The prespecified RFs included body mass index (BMI) ≥30 kg/m<sup>2</sup>, >5% fluctuation in BMI, obstructive sleep apnea with continuous positive airway pressure noncompliance, uncontrolled hypertension, uncontrolled diabetes, uncontrolled hyperlipidemia, tobacco use, alcohol use higher than the standard recommendation, and a diagnosis-to-ablation time (DAT) >1.5 years. The primary outcome was a composite of arrhythmia recurrence, cardiovascular admissions, and cardiovascular death. In this study, a high prevalence of preablation modifiable RFs was observed. More than 50% of the 724 study patients had uncontrolled hyperlipidemia, a BMI ≥30 mg/m<sup>2</sup>, a fluctuating BMI >5%, or a delayed DAT. During a median follow-up of 2.6 (interquartile range 1.4 to 4.6) years, 467 patients (64.5%) met the primary outcome. Independent RFs were a fluctuation in BMI >5% (hazard ratio [HR] 1.31, p = 0.008), diabetes with A<sub>1c</sub> ≥6.5% (HR 1.50, p = 0.014), and uncontrolled hyperlipidemia (HR 1.30, p = 0.005). A total of 264 patients (36.46%) had at least 2 of these predictive RFs, which was associated with a higher incidence of the primary outcome. Delayed DAT over 1.5 years did not alter the ablation outcome. In conclusion, substantial portions of patients who underwent AF ablation have potentially modifiable RFs that were not well controlled. Fluctuating BMI, diabetes with hemoglobin A<sub>1c</sub> ≥6.5%, and uncontrolled hyperlipidemia portend an increased risk of recurrent arrhythmia, cardiovascular hospitalizations, and mortality after ablation.</AbstractText><br /><br />Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 16 May 2023; 198:38-46</small></div>

<div><h4>Comprehensive Prediction of Subclinical Coronary Atherosclerosis in Subjects Without Traditional Cardiovascular Risk Factors.</h4><i>Park S, Jeon YJ, Ann SH, Kim YG, ... Han S, Park GM</i><br /><AbstractText>It is not uncommon for asymptomatic individuals without identified cardiovascular risk factors to present with atherosclerosis-related adverse events. We aimed to evaluate the predictors of subclinical coronary atherosclerosis in individuals without traditional cardiovascular risk factors. We analyzed 2,061 individuals without identified cardiovascular risk factors who voluntarily underwent coronary computed tomography angiography as part of a general health examination. Subclinical atherosclerosis was defined as the presence of any coronary plaque. Of 2,061 individuals, subclinical atherosclerosis was observed in 337 individuals (16.4%). Clinical variables, such as age, gender, body mass index (BMI), systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), were significantly associated with subclinical coronary atherosclerosis. The participants were randomly split into train and validation data sets. In the train set, a prediction model using 6 variables with optimal cutoffs (age >53 years for men and >55 years for women, gender, BMI >22 kg/m<sup>2</sup>, SBP >120 mm Hg, HDL-C <55 mg/100 ml, and LDL-C >130 mg/100 ml) was derived (area under the curve 0.780, 95% confidence interval 0.751 to 0.809, goodness-of-fit p = 0.693). In the validation set, this model performed well (area under the curve 0.792, 95% confidence interval 0.726 to 0.858, goodness-of-fit p = 0.073). In conclusion, together with nonmodifiable risk factors, such as age and gender, modifiable variables, such as BMI, SBP, LDL-C, and HDL-C, were shown to be associated with subclinical coronary atherosclerosis, even at currently acceptable levels. These results suggest that stricter control of BMI, blood pressure, and cholesterol might be helpful in the primary prevention of future coronary events.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Long-Term Prognostic Impact of Pulmonary Hypertension After Venous Thromboembolism.</h4><i>Bonnesen K, Klok FA, Andersen MJ, Andersen A, ... Sørensen HT, Schmidt M</i><br /><AbstractText>Pulmonary embolism is a risk factor for chronic thromboembolic pulmonary hypertension (CTEPH), but the prognostic impact of CTEPH on venous thromboembolism (VTE) mortality remains unclear. We examined the impact of CTEPH and other pulmonary hypertension (PH) subtypes on long-term mortality after VTE. We conducted a nationwide, population-based cohort study of all adult Danish patients alive 2 years after incident VTE without previous PH from 1995 to 2020 (n = 129,040). We used inverse probability of treatment weights in a Cox model to calculate standardized mortality rate ratios (SMRs) of the association between receiving a first-time PH diagnosis ≤2 years after incident VTE and mortality (all-cause, cardiovascular, and cancer). We grouped PH as PH associated with left-sided cardiac disease (group II), PH associated with lung diseases and/or hypoxia (group III), CTEPH (group IV), and unclassified (remaining patients). Total follow-up was 858,954 years. The SMR associated with PH overall was 1.99 (95% confidence interval 1.75 to 2.27) for all-cause, 2.48 (1.90 to 3.23) for cardiovascular, and 0.84 (0.60 to 1.17) for cancer mortality. The SMR for all-cause mortality was 2.62 (1.77 to 3.88) for group II, 3.98 (2.85 to 5.56) for group III, 1.88 (1.11 to 3.20) for group IV, and 1.73 (1.47 to 2.04) for unclassified PH. The cardiovascular mortality rate was increased approximately threefold for groups II and III but was not increased for group IV. Only group III was associated with increased cancer mortality. In conclusion, PH diagnosed ≤2 years after incident VTE was associated with an overall twofold increased long-term mortality driven by cardiovascular causes.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Medium-Term Outcomes of the Different Antithrombotic Regimens After Transcatheter Aortic Valve Implantation.</h4><i>Naser JA, Kucuk HO, Gochanour BR, Scott CG, ... Nkomo VT, Pislaru SV</i><br /><AbstractText>Bioprosthetic valve thrombosis is associated with accelerated bioprosthesis degeneration and valve re-replacement. Whether 3-month warfarin use after transcatheter aortic valve implantation (TAVI) protects against such consequences is unknown. We aimed to investigate if 3-month warfarin treatment after TAVI is associated with better outcomes than dual antiplatelet therapy (DAPT) and single antiplatelet therapy (SAPT) at medium-term follow-up. Adults who underwent TAVI were identified retrospectively (n = 1,501) and classified into warfarin, DAPT, and SAPT groups based on antithrombotic regimen received. Patients with atrial fibrillation were excluded. Outcomes and valve hemodynamics were compared between the groups. Annualized change from baseline in mean gradients and effective orifice area at last follow-up echocardiography was calculated. Overall, 844 patients were included (mean age: 80 ± 9 years, 43% women; 633 receiving warfarin, 164 DAPT, and 47 SAPT). Median time to follow-up was 2.5 (interquartile range 1.2 to 3.9) years. There were no differences in the adjusted outcome end points of ischemic stroke, death, valve re-replacement/intervention, structural valve degeneration, or their composite end point at follow-up. Annualized change in aortic valve area was significantly higher in DAPT (-0.11 [0.19] cm<sup>2</sup>/year) than warfarin (-0.06 [0.25] cm<sup>2</sup>/y, p = 0.03), but annualized change in mean gradients was not different (p >0.05). In conclusion, antithrombotic regimen, including warfarin, after TAVI was associated with marginally lower decrease in aortic valve area but no difference in medium-term clinical outcomes compared with DAPT and SAPT.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Impact of Gender, Race, and Insurance Status on Inhospital Management and Outcomes in Patients With COVID-19 and ST-Elevation Myocardial Infarction (a Nationwide Analysis).</h4><i>Patel KN, Majmundar M, Vasudeva R, Doshi R, ... Mehta H, Gupta K</i><br /><AbstractText>There is a paucity of data exploring the impact of gender, race, and insurance status on invasive management and inhospital mortality in patients with COVID-19 with ST-elevation myocardial infarction (STEMI) in the United States. The National Inpatient Sample database for the year 2020 was queried to identify all adult hospitalizations with STEMI and concurrent COVID-19. A total of 5,990 patients with COVID-19 with STEMI were identified. Women had 31% lower odds of invasive management and 32% lower odds of coronary revascularization than men. Black patients had lower odds of invasive management (odds ratio [OR] 0.61, 95% confidence interval [CI] 0.43 to 0.85, p = 0.004) than White patients. Black and Asian patients had lower odds of percutaneous coronary intervention (Black: OR 0.55, 95% CI 0.38 to 0.80, p = 0.002; Asian: OR 0.39, 95% CI 0.18 to 0.85, p = 0.018) than White patients. Uninsured patients had higher odds of getting percutaneous coronary intervention (OR 1.78, 95% CI 1.05 to 2.98, p = 0.031) and lower odds of inhospital mortality (OR 0.41, 95% CI 0.19 to 0.89, p = 0.023) than privately insured patients. Patients with out-of-hospital STEMI had 19 times higher odds of invasive management and 80% lower odds of inhospital mortality than inhospital STEMI. In conclusion, we note important gender and racial disparities in invasive management of patients with COVID-19 with STEMI. Surprisingly, uninsured patients had higher revascularization rates and lower mortality than privately insured patients.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Ticagrelor as Compared to Clopidogrel Following Percutaneous Coronary Intervention for Acute Coronary Syndrome.</h4><i>Wiens EJ, Leon SJ, Whitlock R, Tangri N, Shah AH</i><br /><AbstractText>Dual antiplatelet therapy with acetylsalicylic acid and a P2Y12 inhibitor has become a mainstay of therapy after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Although higher-potency P2Y12 inhibitors are preferred over clopidogrel in major society guidelines, recent evidence has questioned the extent of the benefit. It is important to evaluate the relative efficacy and safety of P2Y12 inhibitors in a real-world setting. This is a retrospective cohort study of all patients who underwent PCI for ACS in a Canadian province from January 1, 2015 to March 31, 2020. Baseline characteristics, including co-morbidities, medications, and bleeding risk, were obtained. Propensity matching was used to compare patients who received ticagrelor versus clopidogrel. The primary outcome was occurrence of major adverse cardiovascular events (MACEs) at 12 months, defined as death, nonfatal myocardial infarction, or unplanned revascularization. Secondary outcomes included all-cause mortality, major bleeding, stroke, and all-cause hospitalization. A total of 6,665 patients were included; 2,108 received clopidogrel and 4,214 received ticagrelor. Patients who received clopidogrel were older, had more co-morbidities, including cardiovascular risk factors, and had a higher bleeding risk. In 1.925 propensity score-matched pairs, ticagrelor was associated with a significantly lower risk of MACE (hazard ratio 0.79, 0.67 to 0.93, p <0.01) and hospitalization (hazard ratio 0.85, 0.77 to 0.95, p <0.01). No difference was observed in the risk of major bleeding. A statistically nonsignificant trend toward reduced risk of all-cause mortality was noted. In conclusion, in a real-world high-risk cohort, ticagrelor was associated with decreased risk of MACE and all-cause hospitalization compared with clopidogrel after PCI for ACS.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Contemporary Trends, Characteristics, and Outcomes of Transcatheter Aortic Valve Implantation Among Extreme Elderly Patients.</h4><i>Abdelmottaleb W, Maraey A, Ozbay M, Royfman R, ... Elzanaty A, Elgendy IY</i><br /><AbstractText>Transcatheter aortic valve implantation (TAVI) has been increasingly performed among extreme elderly patients with symptomatic severe aortic stenosis. We aimed to study the trends, characteristics, and outcomes of TAVI among extreme elderly. The National Readmission Database for the years 2016 to 2019 was queried for extreme elderly who underwent TAVI. Linear regression analysis was used to calculate the temporal trends in outcomes. A total of 23,507 TAVI extreme elderly admissions (50.3% women and 95.9% Medicare insurance) were included. The in-hospital mortality and all-cause 30-day readmissions were 2% and 15% and have been stable over years of analysis (p trend = 0.79 and 0.06, respectively). We evaluated complications, such as permanent pacemaker implantation (12%) and stroke (3.2%). Stroke rates did not decrease (3.4% vs 2.9% in 2016 and 2019 [p trend = 0.24]). The mean length of stay improved from 5.5 days in 2016 to 4.3 days in 2019 (p trend <0.01). The rates of early discharge (day ≤3) has improved from 49% in 2016 to 69% in 2019 (p trend <0.01). In conclusion, this nationwide contemporary observational analysis showed that TAVI was associated with low rates of complications in the extreme elderly.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Acute Intraoperative Bioprosthetic Valve Thrombosis Immediately After Protamine Administration.</h4><i>Teng P, Yuan S, Ni Y, Wu S</i><br /><AbstractText>Acute bioprosthetic valve thrombosis (BPVT) is considered a rare complication and has seldom been described. Moreover, acute intraoperative BPVT is exceedingly rare, and its management remains a major clinical challenge. Here, we report a case of acute intraoperative BPVT that occurred immediately after protamine administration. Major resolution of the thrombus and significant improvement of bioprosthetic function were observed after the resumption of cardiopulmonary bypass support for approximately 1 hour. Intraoperative transesophageal echocardiography is important for a prompt diagnosis. Our case describes the spontaneous resolution of BPVT after reheparinization, which might assist in the management of acute intraoperative BPVT.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Changes in Computed-Tomography-Derived Segmental Left Ventricular Longitudinal Strain After Transcatheter Aortic Valve Implantation.</h4><i>Singh GK, Fortuni F, Kuneman JH, Vollema EM, ... Delgado V, Bax JJ</i><br /><AbstractText>Patients with severe aortic stenosis (AS) may show left ventricular (LV) apical longitudinal strain sparing. Transcatheter aortic valve implantation (TAVI) improves LV systolic function in patients with severe AS. However, the changes in regional longitudinal strain after TAVI have not been extensively evaluated. This study aimed to characterize the effect of the pressure overload relief after TAVI on LV apical longitudinal strain sparing. A total of 156 patients (mean age 80 ± 7 years, 53% men) with severe AS who underwent computed tomography before and within 1 year after TAVI (mean time to follow-up 50 ± 30 days) were included. LV global and segmental longitudinal strain were assessed using feature tracking computed tomography. LV apical longitudinal strain sparing was evaluated as the ratio between the apical and midbasal longitudinal strain and was defined as an LV apical to midbasal longitudinal strain ratio >1. LV apical longitudinal strain remained stable after TAVI (from 19.5 ± 7.2% to 18.7 ± 7.7%, p = 0.20), whereas LV midbasal longitudinal strain showed a significant increase (from 12.9 ± 4.2% to 14.2 ± 4.0%, p ≤0.001). Before TAVI, 88% of the patients presented with LV apical strain ratio >1% and 19% presented with an LV apical strain ratio >2. After TAVI, these percentages significantly decreased to 77% and 5% (p = 0.009, p ≤0.001), respectively. In conclusion, LV apical sparing of strain is a relatively common finding in patients with severe AS who underwent TAVI and its prevalence decreases after the afterload relief after TAVI.</AbstractText><br /><br />Copyright © 2023 The Authors.

<div><h4>Coronary Volume to Left Ventricular Mass Ratio in Patients With Hypertension.</h4><i>van Rosendael SE, van Rosendael AR, Kuneman JH, Patel MR, ... Saraste A, Knuuti J</i><br /><AbstractText>The coronary vascular volume to left ventricular mass (V/M) ratio assessed by coronary computed tomography angiography (CCTA) is a promising new parameter to investigate the relation of coronary vasculature to the myocardium supplied. It is hypothesized that hypertension decreases the ratio between coronary volume and myocardial mass by way of myocardial hypertrophy, which could explain the detected abnormal myocardial perfusion reserve reported in patients with hypertension. Individuals enrolled in the multicenter ADVANCE (Assessing Diagnostic Value of Noninvasive FFRCT in Coronary Care) registry who underwent clinically indicated CCTA for analysis of suspected coronary artery disease with known hypertension status were included in current analysis. The V/M ratio was calculated from CCTA by segmenting the coronary artery luminal volume and left ventricular myocardial mass. In total, 2,378 subjects were included in this study, of whom 1,346 (56%) had hypertension. Left ventricular myocardial mass and coronary volume were higher in subjects with hypertension than normotensive patients (122.7 ± 32.8 g vs 120.0 ± 30.5 g, p = 0.039, and 3,105.0 ± 992.0 mm<sup>3</sup> vs 2,965.6 ± 943.7 mm<sup>3</sup>, p <0.001, respectively). Subsequently, the V/M ratio was higher in patients with hypertension than those without (26.0 ± 7.6 mm<sup>3</sup>/g vs 25.3 ± 7.3 mm<sup>3</sup>/g, p = 0.024). After correcting for potential confounding factors, the coronary volume and ventricular mass remained higher in patients with hypertension (least square) mean difference estimate: 196.3 (95% confidence intervals [CI] 119.9 to 272.7) mm<sup>3</sup>, p <0.001, and 5.60 (95% CI 3.42 to 7.78) g, p <0.001, respectively), but the V/M ratio was not significantly different (least square mean difference estimate: 0.48 (95% CI -0.12 to 1.08) mm<sup>3</sup>/g, p = 0.116). In conclusion, our findings do not support the hypothesis that the abnormal perfusion reserve would be caused by reduced V/M ratio in patients with hypertension.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Outcomes of Ventricular Tachycardia Catheter Ablation in Patients Who Underwent Cardiac Defibrillator Implantation Nationwide Readmission Database Analysis.</h4><i>Moustafa A, Elzanaty A, Karim S, Eltahawy E, ... Maraey A, Chacko P</i><br /><AbstractText>The timing of when to perform ventricular tachycardia (VT) ablation while receiving an implantable cardioverter defibrillator (ICD) during the same hospitalization has not been explored. This study aimed to investigate the use and outcomes of VT catheter ablation in patients with sustained VT receiving ICD in the same hospital stay. The Nationwide Readmission Database 2016 to 2019 was queried for all hospitalizations with a primary diagnosis of VT with subsequent ICD during the same admission. Hospitalizations were later stratified according to whether a VT ablation was performed. All catheter ablation of VT were performed before ICD implantation. The outcomes of interest were in-hospital mortality and 90-day readmission. A total of 29,385 VT hospitalizations were included. VT ablation was performed with subsequent ICD placement in 2,255 (7.6%), whereas 27,130 (92.3%) received an ICD only. No differences were found regarding in-hospital mortality (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.35 to 1.9, p = 0.67) and all-cause 90-day readmission rate (aOR 1.1, 95% CI 0.95 to 1.3, p = 0.16). An increase in readmission because of recurrent VT was noted in the VT ablation group (aOR 1.53, 8% vs 5% CI 1.2 to 1.9, p <0.01); the VT ablation group encompassed a higher number of patients with heart failure with reduced ejection fraction (p <0.01), cardiogenic shock (p <0.01), and mechanical circulatory support use (p <0.01). In conclusion, the use of VT ablation in patients admitted with sustained VT is low and reserved for higher risk patients with significant co-morbidities. Despite the higher risk profile of VT ablation cohort, no differences were found in the short-term mortality and readmission rate between the groups.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Coronary Lithotripsy as Elective or Bail-Out Strategy After Rotational Atherectomy in the Rota-Shock Registry.</h4><i>Sardella G, Stefanini G, Leone PP, Boccuzzi G, ... Tomai F, Mancone M</i><br /><AbstractText>Debulking lesions with severe coronary artery calcification (CAC) is highly recommended to obtain good procedural and long-term success. Utilization and performance of coronary intravascular lithotripsy (IVL) after rotational atherectomy (RA) has not been thoroughly studied. This study aimed to evaluate the efficacy and safety of IVL with the Shockwave Coronary Rx Lithotripsy System in lesions with severe CAC as elective or bail-out strategy after RA. This observational, prospective, single-arm, multicenter, international, open-label Rota-Shock registry included patients with symptomatic coronary artery disease and lesions with severe CAC treated by percutaneous coronary intervention, including lesion preparation with RA and IVL, at 23 high-volume centers. Primary efficacy end point was procedural success, defined as final diameter stenosis <30% by quantitative coronary angiography. Primary safety end point was freedom from serious angiographic complications, which included >National Heart, Lung and Blood Institute type B dissection, perforation, abrupt closure, slow or no flow, final thrombolysis in myocardial infarction flow <3, and acute thrombosis. A total of 160 patients were enrolled between June 2020 and June 2022. The primary efficacy end point was observed in 155 patients (96.9%). The primary safety end point occurred in 145 cases (90.6%). Dissections >National Heart, Lung and Blood Institute type B occurred in 3 patients (1.9%), whereas slow or no flow occurred in 8 (5.0%), final thrombolysis in myocardial infarction flow <3 in 3 (1.9%), and perforation in 4 patients (2.5%). Free from inhospital major adverse cardiac and cerebrovascular events, including cardiac death, target vessel myocardial infarction, target lesion revascularization, cerebrovascular accident, definite/probable stent thrombosis, and major bleeding, occurred in 158 patients (98.7%). In conclusion, IVL after RA in lesions with severe CAC was effective and safe, with a very low incidence of complications as either elective or bail-out strategy.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Relative Contribution of Atrial Fibrillation to Outcomes of Patients With Cardiomyopathy Based on Severity of Left Ventricular Dysfunction.</h4><i>Ayub MT, Rangavajla G, Thoma F, Mulukutla S, ... Jain S, Saba S</i><br /><AbstractText>In patients with left ventricular (LV) dysfunction, the risk of death or heart failure hospitalizations (HFHs) increases with worsening ejection fraction (EF). Whether the relative contribution of atrial fibrillation (AF) to outcomes is more pronounced in patients with worse EF is not confirmed. The present study aimed to investigate the relative influence of AF on the outcome of cardiomyopathy patients by severity of LV dysfunction. In this observational study, data from 18,003 patients with EF ≤50% seen at a large academic institution between 2011 and 2017 were analyzed. Patients were stratified by EF quartiles (EF<25%, 25%≤EF<35%, 35%≤EF<40%, and EF≥40%, for quartiles 1, 2, 3, and 4, respectively). and followed to the end point of death or HFH. Outcomes of AF versus non-AF patients were compared within each EF quartile. During a median follow-up of 3.35 years, 8,037 patients (45%) died and 7,271 (40%) had at least 1 HFH. Rates of HFH and all-cause mortality increased as EF decreased. The hazard ratios (HRs) of death or HFH for AF versus non-AF patients increased steadily with increasing EF (HR of 1.22, 1.27, 1.45, 1.50 for quartiles 1, 2, 3, and 4, respectively, p = 0.045) driven primarily by the risk of HFH (HR of 1.26, 1.45, 1.59, 1.69 for quartiles 1, 2, 3, and 4, respectively, p = 0.045). In conclusion, in patients with LV dysfunction, the detrimental influence of AF on the risk of HFH is more pronounced in those with more preserved EF. Mitigation strategies for AF with the goal of decreasing HFH may be more impactful in patients with more preserved LV function.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Transcatheter Aortic Valve Implantation in Cardiac Amyloidosis and Aortic Stenosis.</h4><i>Riley JM, Junarta J, Ullah W, Siddiqui MU, ... Rajapreyar IN, Brailovsky Y</i><br /><AbstractText>Aortic stenosis (AS) and cardiac amyloidosis (CA) occur concomitantly in a significant number of patients and portend a higher risk of all-cause mortality. Previous studies have investigated outcomes in patients with concomitant CA/AS who underwent transcatheter aortic valve implantation (TAVI) versus medical therapy alone, but no evidence-based consensus regarding the ideal management of these patients has been established. Medline, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. Methodologic bias was assessed using the modified Newcastle-Ottawa scale for observational studies. A total of 4 observational studies comprising 83 patients were included. Of these, 45 patients (54%) underwent TAVI, whereas 38 (46%) were managed conservatively. Of the 3 studies that included baseline characteristics by treatment group, 30% were women. The risk of all-cause mortality was found to be significantly lower in patients who underwent TAVI than those treated with conservative medical therapy alone (odds ratio 0.24, 95% confidence interval 0.08 to 0.73). In conclusion, this meta-analysis suggests a lower risk of all-cause mortality in patients with CA with AS who underwent TAVI than those managed with medical therapy alone.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Impact of Diabetes Mellitus on Benefit of β-Blocker Therapy After Myocardial Infarction.</h4><i>Zaatari G, Bello D, Blandon C, Abbott JD, ... Goldberger JJ, Outcomes of Beta-Blocker Therapy After Myocardial Infarction Investigators</i><br /><AbstractText>Beta blockers are uniformly recommended for all patients after myocardial infarction (MI), including those with diabetes mellitus (DM). This study assesses the impact of β-blocker type and dosing on survival in patients with DM after MI. A cohort of 6,682 patients in the Outcomes of Beta-blocker Therapy After Myocardial INfarction registry were discharged after MI. In this cohort, 2,137 patients had DM (32%). Beta-blocker dose was indexed to the target daily dose used in randomized clinical trials and reported as percentage. Dosage groups were: no β blocker, >0% to 12.5%, >12.5% to 25%, >25% to 50%, and >50% of the target dose. The overall mean discharge β-blocker dose in patients with DM was 42.7 ± 34.1% versus 35.9 ± 27.4% in patients without DM (p <0.0001). Patients with DM were prescribed carvedilol at a higher rate than those without DM (27.8% vs 19.6%). The 3-year mortality estimates were 24.4% and 12.8% for patients with DM versus without DM (p <0.0001), respectively, with an unadjusted hazard ratio = 1.820 (confidence interval 1.587 to 2.086, p <0.0001). Patients with DM in the >12.5% to 25% dose category had the highest survival rates, whereas patients in the >50% dose had the lowest survival rate among patients discharged on β blockers (p <0.0001). In the multivariable analysis among patients with DM after MI, all β-blocker dose categories demonstrated lower mortality than no therapy; however, only the >12.5% to 25% dose had a statistically significant hazard ratio 0.450 (95% confidence interval 0.224 to 0.907, p = 0.025). In patients with DM, there was no statistically significant difference in 3-year mortality among those treated with metoprolol versus carvedilol. In conclusion, our analysis in patients with DM after MI suggested a survival benefit from β-blocker therapy, with no apparent advantage to high- versus low-dose β-blocker therapy; although, physicians tended to prescribe higher doses in patients with DM. There was no survival benefit for carvedilol over metoprolol in patients with DM.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Outcomes After Left Main Percutaneous Coronary Intervention in Patients With Acute Myocardial Infarction Complicated by Cardiogenic Shock (from the German ALKK PCI Registry).</h4><i>El Nasasra A, Hochadel M, Zahn R, Schneider A, ... Zeymer U, ALKK-Study Group</i><br /><AbstractText>Early revascularization therapy with percutaneous coronary intervention (PCI) has been shown to improve outcomes in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS). Data from consecutive patients with AMI and CS treated with PCI enrolled into the prospective Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte-PCI registry were centrally collected and analyzed. Patients were divided into 4 groups with PCI for left main (LM), 1-vessel, 2-vessel, and 3-vessel diseases. Patients\' characteristics, procedural features, antithrombotic therapies, and in-hospital complications were compared between the 4 groups. Between 2010 and 2015 a total of 2,348 consecutive patients with AMI and CS were treated by PCI in 51 hospitals, 295 for LM (15 for protected, 280 for unprotected) and single-vessel (n = 491), 2-vessel (n = 524), and 3-vessel disease (n = 1,038). Thrombolysis in myocardial infarction 3 patency of the culprit lesion after PCI was 84.3%, 84.0%, 80.8%, and 84.6% in single-vessel, 2-vessel, 3-vessel disease, and LM PCI, respectively, whereas in-hospital mortality was 27.9%, 33.9%, 46.5%, and 55.9%. Bleeding rates were low (2.0%-2.3 %) and not different between groups. In a multivariate analysis a higher age, thrombolysis in myocardial infarction flow <3 after PCI, 3-vessel disease, and LM PCI were independent predictors of mortality. In conclusion, PCI of the LM is performed in about 12.5% of patients with AMI and CS and was associated with a high procedural success rate, whereas mortality is increased with LM PCI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Procedural Time and Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention.</h4><i>Rempakos A, Kostantinis S, Simsek B, Karacsonyi J, ... Burke MN, Brilakis ES</i><br /><AbstractText>Chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) can be lengthy procedures. We sought to investigate the effect of procedural time on CTO PCI outcomes. We examined the procedural time required for the various steps of CTO PCI in 6,442 CTO PCIs at 40 US and non-US centers between 2012 and 2022. The mean and median procedure times were 129 ± 76 and 112 minutes, respectively, with no significant change over time. The median times from access to wire insertion, guidewire manipulation time, and post crossing were 20, 32, and 53 minutes, respectively. Lesions crossed in <30 minutes were less complex, as reflected by lower Japanese CTO score (1.89 ± 1.19, p <0.001) than lesions that were not successfully crossed (2.88 ± 1.22) and lesions that were crossed in ≥30 minutes (2.85 ± 1.13). The likelihood of successful crossing if crossing was not achieved after 30, 90, and 180 minutes were a 76.7%, 60.7%, and 42.7%, respectively. The parameters independently associated with ≥30 minutes guidewire manipulation time in patients with a primary antegrade approach included left anterior descending target vessel, proximal cap ambiguity, blunt/no stump, occlusion length, previous failed attempt, medium/severe calcification, and medium/severe tortuosity. The mean duration of CTO PCI is approximately 2 hours (∼20% of time for access to wire insertion, ∼30% wire manipulation time, and ∼50% postwiring time). Guidewire crossing time was shorter in less complex lesions and in cases without complications.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Association of Nondihydropyridine Calcium Channel Blockers Versus β-Adrenergic Receptor Blockers With Risk of Heart Failure Hospitalization.</h4><i>Meyer M, Wetmore JB, Weinhandl ED, Roetker NS</i><br /><AbstractText>Heart failure (HF) with preserved ejection fraction (HFpEF) and atrial fibrillation (AF) are interrelated and often coexisting conditions in older adults. Although equally recommended, nondihydropyridine calcium channel blockers (non-DHP CCBs), such as diltiazem and verapamil, are less often used than β blockers. Because recent studies suggested that β-blocker use in both HFpEF and AF may increase the risk for HF, we tested whether non-DHP CCBs were associated with lower HF hospitalization risk than β blockers. We examined fee-for-service Medicare beneficiaries who were aged ≥66 years, had HFpEF or AF, and newly initiated a β blocker (n = 83,458) or non-DHP CCB (n = 18,924) from 2014 to 2018. The outcomes of HF hospitalization and all-cause mortality were analyzed using multivariable-adjusted Cox regression in the full cohort and, separately, in the subset without a recent hospital or skilled nursing discharge. Follow-up was analyzed using 2 frameworks: intention-to-treat and censored-at-drug-switch-or-discontinuation. There was a modestly protective association of non-DHP CCBs for the risk of HF hospitalization. Before drug switch or discontinuation, the use of diltiazem or verapamil was associated with decreased risk of HF hospitalization in the full cohort (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.81 to 1.00, p = 0.05) and in the subgroup (HR 0.70, 95% CI 0.56 to 0.89, p = 0.003). However, the association with all-cause mortality tended to favor β blockers, including in the intention-to-treat analysis (HR 1.21, 95% CI 1.17 to 1.25, p <0.001). In conclusion, compared with β blockers, the initiation of diltiazem or verapamil in patients with HFpEF or AF may be associated with fewer HF hospitalization events but also with more all-cause deaths.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>High-Burden Premature Atrial Contractions Predict New-Onset Atrial Fibrillation After Surgical Septal Myectomy.</h4><i>Meng Y, Nie C, Zhang Y, Zhu C, ... Wu Z, Wang S</i><br /><AbstractText>Although increased premature atrial contractions (PACs) reportedly predict atrial fibrillation (AF) in both general and specific (e.g., patients with stroke) populations, early postoperative AF (POAF) risk in patients with increased PAC burden who require cardiac surgery remains unclear. We examined the correlation between different preoperative PAC burdens and POAF in patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent surgical treatment. We analyzed 304 consecutively admitted patients with OHCM without previous AF who underwent isolated septal myectomy between January 2015 and December 2018. All patients underwent preoperative 24-hour Holter electrocardiogram monitoring. PACs were present in 259 patients (85.20%) and absent in 45 patients (14.80%). According to the cut-off PAC number of 100 beats/24 hours, there were 211 patients (69.41%) with low-burden PACs and 48 patients (15.79%) with high-burden PACs. AF after septal myectomy occurred in 73 patients, which consisted of 3/45 in the non-PAC group (6.67%), 47/211 in the low-PAC-burden group (22.27%), and 23/48 in the high PAC burden group (47.92%). POAF incidence was higher in both low- and high-burden patients than in patients without PAC (p <0.01). Multivariate logistic regression analyses demonstrated that high-burden PACs (p = 0.02) and age (p <0.01) but not low-burden PACs (p = 0.22) independently predicted POAF in patients with OHCM. The area under the receiver operating characteristic curve for preoperative PACs was 0.72 (95% confidence interval 0.66 to 0.79, p <0.01, sensitivity: 68.49%, specificity: 69.26%). In conclusion, POAF incidence was significantly higher in patients with preoperative high-burden PACs and can predict POAF in patients with OHCM.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Cardiology Care and Loss to Follow-Up Among Adults With Congenital Heart Defects in CH STRONG.</h4><i>Andrews JG, Strah D, Downing KF, Kern MC, ... Farr SL, Klewer SE</i><br /><AbstractText>Many of the estimated 1.4 million adults with congenital heart defects (CHDs) in the United States are lost to follow-up (LTF) despite recommendations for ongoing cardiology care. Using 2016 to 2019 CH STRONG (Congenital Heart Survey To Recognize Outcomes, Needs, and well-beinG) data, we describe cardiac care among community-based adults with CHD, born in 1980 to 1997, identified through state birth defects registries. Our estimates of LTF were standardized to the CH STRONG eligible population and likely more generalizable to adults with CHD than clinic-based data. Half of our sample were LTF and more than 45% had not received cardiology care in over 5 years. Of those who received care, only 1 in 3 saw an adult CHD physician at their last encounter. Not knowing they needed to see a cardiologist, being told they no longer needed cardiology care, and feeling \"well\" were the top reasons for LTF, and only half of respondents report doctors discussing the need for cardiac follow-up.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Pacing-Related Differences After SAPIEN-3 TAVI: Clinical and Echocardiographic Correlates.</h4><i>Sammour YM, Lak H, Gajulapalli RD, Chawla S, ... Krishnaswamy A, Kapadia SR</i><br /><AbstractText>Data regarding the impact of pacing on outcomes after transcatheter aortic valve implantation (TAVI) is evolving especially with regards to pre-existing permanent pacemaker (PPM). We examined the impact of new and previous PPM on the clinical and hemodynamic outcomes after SAPIEN-3 TAVI. We included all consecutive patients who underwent transfemoral TAVI using SAPIEN-3 valve from 2015 to 2018 at our institution. Among 1,028 patients, 10.2% required a new PPM within 30 days, whereas 14% had a pre-existing PPM. The presence of either previous or new PPM had no impact on the 3-year mortality (log-rank p = 0.6) or 1-year major adverse cardiac and cerebrovascular events (log-rank p = 0.65). New PPM was associated with lower left ventricular (LV) ejection fraction (LVEF) at both 30 days (54.4 ± 11.3% vs 58.4 ± 10.1%, p = 0.001) and 1 year (54.2 ± 12% vs 59.1 ± 9.9%, p = 0.009) than no PPM. Similarly, previous PPM was associated with worse LVEF at 30 days (53.6 ± 12.3%, p <0.001) and 1 year (55.5 ± 12.1%, p = 0.006) than no PPM. Interestingly, new PPM was associated with lower 1-year mean gradient (11.4 ± 3.8 vs 12.6 ± 5.6 mm Hg, p = 0.04) and peak gradient (21.3 ± 6.5 vs 24.1 ± 10.4 mm Hg, p = 0.01), despite no baseline differences. Previous PPM was also associated with lower 1-year mean gradient (10.3 ± 4.4 mm Hg, p = 0.001) and peak gradient (19.4 ± 8 mm Hg, p <0.001) and higher Doppler velocity index (0.51 ± 0.12 vs 0.47 ± 0.13, p = 0.039). Moreover, 1-year LV end-systolic volume index was higher with new (23.2 ± 16.1 vs 20 ± 10.8 ml/m<sup>2</sup>, p = 0.038) and previous PPM (24.5 ± 19.7, p = 0.038) than no PPM. Previous PPM was associated with higher moderate-to-severe tricuspid regurgitation (35.3% vs 17.7%, p <0.001). There were no differences regarding the rest of the studied echocardiographic outcomes at 1 year. In conclusion, new and previous PPM did not affect 3-year mortality or 1-year major adverse cardiac and cerebrovascular events; however, they were associated with worse LVEF, higher 1-year LV end-systolic volume index, and lower mean and peak gradients on follow-up than no PPM.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Risk Factors for Short-Term Versus Long-Term Mortality in Patients Who Underwent Cardiac Resynchronization Therapy.</h4><i>Galloo X, Khidir M, Stassen J, Hirasawa K, ... Ajmone Marsan N, Bax JJ</i><br /><AbstractText>Cardiac resynchronization therapy (CRT) is an effective therapy in selected patients with advanced heart failure that reduces all-cause mortality at short-term follow-up. However, data regarding long-term mortality after CRT implantation are scarce, with no separate analysis available of the covariates associated with respectively short-term and long-term outcomes. Accordingly, the present study evaluated the risk factors associated with short-term (2-year follow-up) versus long-term (10-year follow-up) mortality after CRT implantation. Patients who underwent CRT implantation and had echocardiographic evaluation before implantation were included in the present study. The primary end point was all-cause mortality, and independent associates of short-term (2-year follow-up) and long-term (10-year follow-up) mortality were compared. In total, 894 patients (mean age 66 ± 10 years, 76% males) who underwent CRT implantation were included in the present study. The cumulative overall survival rates for the total population were 91%, 71%, and 45% at 2-, 5- and 10-year follow-up, respectively. Multivariable Cox regression analysis showed that short-term mortality was associated with both clinical and echocardiographic variables at the moment of CRT implantation; whereas long-term mortality was predominantly associated with baseline clinical parameters and was less strongly associated with baseline echocardiographic parameters. In conclusion, at long-term (10-year) follow-up, a significant proportion (45%) of patients with advanced heart failure who underwent CRT implantation were still alive. Importantly, the risk assessment for short-term (2-year follow-up) and long-term (10-year follow-up) mortality differ considerably, which may influence clinical decision making.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Sex-Specific Differences in Aortic Valve Calcification Between Bicuspid and Tricuspid Severe Aortic Stenosis.</h4><i>Veulemans V, Hokken TW, Heermann J, Kardys I, ... Zeus T, Van Mieghem NM</i><br /><AbstractText>Sex-specific thresholds of aortic valve calcification (AVC) correlate with aortic stenosis (AS) and may complement echocardiography to determine AS severity. Importantly, current guideline-recommended thresholds of AVC scores derived by multislice computed tomography do not distinguish between bicuspid and tricuspid aortic valves. The objective of this study was to evaluate the sex-specific differences in the amount of AVC in patients with severe AS and tricuspid (TAV) versus bicuspid (BAV) aortic valve morphologies, retrospectively evaluated by 2 tertiary care institutions. The inclusion criteria comprised patients with severe AS and a left ventricular ejection fraction ≥50% and suitable imaging examinations. The study included 1,450 patients (723 men; 49.9%) with severe AS, including 1,335 patients with TAV (92.1%) and 115 with BAV (17.9%). The calculated Agatston score was higher in BAV patients (men: BAV 4,358 [2,644 to 6,005] AU vs TAV 2,643 [1,727 to 3,794] AU, p <0.01; women: BAV 2,174 [1,330 to 4,378] AU vs TAV 1,703 [964 to 2,534] AU, p <0.01), also when indexed for valve dimensions and body surface area (men: BAV 2,227 [321 to 3,105] AU/m<sup>2</sup> vs TAV 1,333 [872 to 1,913] AU/m<sup>2</sup>, p <0.01; women: BAV 1,326 [782 to 2,148] AU/m<sup>2</sup> vs TAV 930 [546 to 1,456] AU/m<sup>2</sup>, p <0.01). Differences between the BAV- and TAV-derived Agatston score was more prominent in concordant severe AS. In conclusion, sex-specific Agatston scores in severe AS were approximately 1/3 higher in patients with BAV than in patients with TAV for both women and men. Optimal AVC thresholds should be adjusted for BAV, also respecting considerable prognostic implications.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Distinct Hemodynamic Responses That Culminate With Postural Orthostatic Tachycardia Syndrome.</h4><i>de Oliveira MCS, Távora-Mehta MZP, Mehta N, Magajevski AS, ... Doubrawa E, Lofrano-Alves MS</i><br /><AbstractText>It is of paramount importance to characterize the individual hemodynamic response of patients with postural orthostatic tachycardia syndrome (POTS) to select the best therapeutic intervention. Our aim in this study was to describe the hemodynamic changes in 40 patients with POTS during the head-up tilt test and compare them with 48 healthy patients. Hemodynamic parameters were obtained by cardiac bioimpedance. Patients were compared in supine position and after 5, 10, 15, and 20 minutes of orthostatic position. Patients with POTS demonstrated higher heart rate (74 beats per minute [64 to 80] vs 67 [62 to 72], p <0.001) and lower stroke volume (SV) (83.0 ml [72 to 94] vs 90 [79 to 112], p <0.001) at supine position. The response to orthostatic challenge was characterized by a decrease in SV index (SVI) in both groups (ΔSVI in ml/m<sup>2</sup>: -16 [-25 to -7.] vs -11 [-17 to -6.1], p = NS). Peripheral vascular resistance (PVR) was reduced only in POTS (ΔPVR in dyne.seg/cm<sup>5</sup>:-52 [-279 to 163] vs 326 [58 to 535], p <0.001). According to the best cut-off points obtained using the receiver operating characteristic analysis for the variation of SVI (-15.5%) and PVR index (PVRI) (-5.5%), we observed 4 distinct groups of POTS: 10% presented an increase in both SVI and PVRI after the orthostatic challenge, 35% presented a PVRI decrease with SVI maintenance or increase, 37.5% presented an SVI decrease with PVRI maintenance or elevation, and 17.5% presented a reduction in both variables. Body mass index, ΔSVI, and ΔPVRI were strongly correlated with POTS (area under the curve = 0.86 [95% confidence interval 0.77 to 0.92], p <0.0001). In conclusion, the use of appropriate cut-off points for hemodynamic parameters using bioimpedance cardiography during the head-up tilt test could be a useful strategy to identify the main mechanism involved and to select the best individual therapeutic strategy in POTS.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Residing in a Food Desert and Adverse Cardiovascular Events in US Veterans With Established Cardiovascular Disease.</h4><i>Lloyd M, Amos ME, Milfred-Laforest S, Motairek IK, ... Pell J, Deo SV</i><br /><AbstractText>Residents living in a \"food desert\" are known to be at a higher risk for developing cardiovascular disease (CVD). However, national-level data regarding the influence of residing in a food desert in patients with established CVD is lacking. Data from veterans with established atherosclerotic CVD who received outpatient care in the Veterans Health Administration system between January 2016 and December 2021 were obtained, with follow-up information collected until May 2022 (median follow-up: 4.3 years). A food desert was defined using the United States Department of Agriculture criteria, and census tract data were used to identify Veterans in these areas. All-cause mortality and the occurrence of major adverse cardiovascular events (MACEs; a composite of myocardial infarction/stroke/heart failure/all-cause mortality) were evaluated as the co-primary end points. The relative risk for MACE in food desert areas was evaluated by fitting multivariable Cox models adjusted for age, gender, race, ethnicity, and median household income, with food desert status as the primary exposure. Of the 1,640,346 patients (mean age 72 years, women 2.7%, White 77.7%, Hispanic 3.4%), 25,7814 (15.7%) belonged to the food desert group. Patients residing in food deserts were younger; more likely to be Black (22% vs 13%)or Hispanic (4% vs 3.5%); and had a higher prevalence of diabetes mellitus (52.7% vs 49.8%), chronic kidney disease (31.8% vs 30.4%,) and heart failure (25.6% vs 23.8%). Adjusted for covariates, food desert patients had a higher risk of MACE (hazard ratio 1.040 [1.033 to 1.047]; p <0.001) and all-cause mortality (hazard ratio 1.032 [1.024 to 1.039]; p <0.001). In conclusion, we observed that a large proportion of US veterans with established atherosclerotic CVD reside in food desert census tracts. Adjusting for age, gender, race, and ethnicity, residing in food deserts was associated with a higher risk of adverse cardiac events and all-cause mortality.</AbstractText><br /><br />Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 22 Apr 2023; 196:70-76</small></div>

<div><h4>Mortality After the First Hospital Admission for Acute Heart Failure, De Novo Versus Acutely Decompensated Heart Failure With Reduced Ejection Fraction.</h4><i>López-Vilella R, Jover Pastor P, Donoso Trenado V, Sánchez-Lázaro I, ... Martínez Dolz L, Almenar Bonet L</i><br /><AbstractText>It is not clear to date whether a first admission in heart failure (HF) marks a worse evolution in patients not previously diagnosed with HF (\"de novo HF\") than those already diagnosed as outpatients (\"acutely decompensated HF\"). The aim of the study was to analyze whether survival in patients admitted for de novo HF differs from the survival in those admitted for a first episode of decompensation but with a previous diagnosis of HF. This study includes an analysis of 1,728 patients admitted for decompensated HF during 9 years. Readmissions and patients with left ventricular ejection fraction ≥50% were excluded (finally, 524 patients analyzed). We compared de novo HF (n = 186) in patients not diagnosed with HF, although their structural heart disease was defined, versus acutely decompensated HF (n = 338). The clinical profiles in both groups were similar. The de novo HF group more frequently presented with normal right ventricular function, with less presence of severe tricuspid regurgitation. The probability of survival was low in both groups. Thus, the median life in the de novo HF group was 2.1 years and in the acutely decompensated HF group, 3.5 years. There was a lower probability of long-term survival in the de novo HF group (p = 0.035). The variables associated with mortality were age (p <0.0001), ischemic heart disease (p <0.0001), hypertension (p = 0.009), obesity (p = 0.025), diabetes (p = 0.001), and N-terminal pro-brain natriuretic peptide at admission (p <0.0001). A higher glomerular filtration rate was associated with better survival (p = 0.033). De novo HF was associated with a higher mortality than chronic HF with acute decompensation (hazard ratio 1.53, 95% confidence interval 1.03 to 2.27, p = 0.036). In conclusion, the first admission for HF decompensation in patients with no previous diagnosis of HF identifies a subgroup of patients with higher long-term mortality.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Association of Kidney Tubule Biomarkers With Cardiac Structure and Function in the Multiethnic Study of Atherosclerosis.</h4><i>Wettersten N, Katz R, Greenberg JH, Gutierrez OM, ... Shlipak M, Ix JH</i><br /><AbstractText>Markers of glomerular disease, estimated glomerular filtration rate (eGFR) and albuminuria, are associated with cardiac structural abnormalities and incident cardiovascular disease (CVD). We aimed to determine whether biomarkers of kidney tubule injury, function, and systemic inflammation are associated with cardiac structural abnormalities. Among 393 Multi-Ethnic Study of Atherosclerosis participants without diabetes, CVD, or chronic kidney disease, we assessed the association of 12 biomarkers of kidney tubule injury, function, and systemic inflammation with the left ventricular mass/volume ratio (LVmvr) and left ventricular ejection fraction (LVEF) on cardiac magnetic resonance imaging using linear regression. The average age was 60 ± 10 years; 48% were men; mean eGFR was 96±16 ml/min/1.73 m<sup>2</sup>; mean LVmvr was 0.93±0.18 g/ml, and mean LVEF was 62±6%. Each twofold greater concentration of plasma soluble urokinase plasminogen activator receptor was associated with a 0.04 g/ml (95% confidence interval [CI] 0.01 to 0.08 g/ml) higher LVmvr and 2.1% (95% CI 0.6 to 3.5%) lower LVEF, independent of risk factors for CVD, eGFR, and albuminuria. Each twofold greater plasma monocyte chemoattractant protein 1 was associated with higher LVmvr with a similar coefficient to that of plasma soluble urokinase plasminogen activator receptor. Each twofold greater concentration of plasma chitinase-3-like protein 1 and urine alpha-1-microglobulin was associated with a 1.1% (95% CI 0.4 to 1.7%) and 1.2% (95% CI 0.2 to 2.2%) lower LVEF, respectively. In conclusion, abnormal kidney tubule health may lead to cardiac dysfunction above and beyond eGFR and albuminuria.</AbstractText><br /><br />Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 20 Apr 2023; 196:11-18</small></div>

<div><h4>Coronary Computed Tomography Angiography Findings of Plaque Erosion.</h4><i>Suzuki K, Kinoshita D, Sugiyama T, Yuki H, ... Kakuta T, Jang IK</i><br /><AbstractText>Compared with plaque rupture, plaque erosion has distinct features, which can be diagnosed only by intravascular optical coherence tomography. Computed tomography angiography (CTA) features of plaque erosion have not been reported. The aim of the present study was to identify the CTA features specific for plaque erosion in patients with non-ST-segment elevation acute coronary syndromes to enable a diagnosis of erosion without invasive procedures. Patients with non-ST-segment elevation acute coronary syndromes who underwent preintervention CTA and optical coherence tomography imaging of culprit lesions were enrolled. Plaque volume and high-risk plaque (HRP) features were assessed by CTA. Among 191 patients, plaque erosion was the underlying mechanism in 89 patients (46.6%) and plaque rupture in 102 patients (53.4%). The total plaque volume (TPV) was lower in plaque erosion than in plaque rupture (133.6 vs 168.8 mm<sup>3</sup>, p = 0.001). Plaque erosion had a lower prevalence of positive remodeling than plaque rupture (75.3% vs 87.3%, p = 0.033). As the number of HRP features decreased, plaque erosion became more prevalent (p = 0.014). In the multivariable logistic regression analysis, lower TPV and less prevalent HRP features were associated with a higher prevalence of plaque erosion. The addition of TPV ≤116 mm<sup>3</sup> and HRP features ≤1 to the known predictors significantly increased the area under the curve of the plaque erosion prediction receiver operator characteristics.

<div><h4>Characteristics of Right Ventricular to Pulmonary Arterial Coupling and Association With Functional Status Among Older Aged Adults from the Multi-Ethnic Study of Atherosclerosis.</h4><i>Mukherjee M, Ogunmoroti O, Jani V, Kapoor K, ... Shah SJ, Michos ED</i><br /><AbstractText>Although the echocardiographic:derived ratio of tricuspid annular plane systolic excursion (TAPSE) to pulmonary arterial systolic pressure (PASP) is an important prognostic tool in heart failure (HF), the relation with 6-minute walk distance (6MWD) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) is less established. We sought to establish the normative values of TAPSE:PASP among older adults without cardiovascular disease (CVD) and evaluate the relation with NT-proBNP and 6MWD. Among 1,542 participants of the Multi-Ethnic Study of Atherosclerosis-HF ancillary study, the cross-sectional association of TAPSE:PASP with the outcomes of 6MWD and NT-proBNP was analyzed using multivariable linear regression, with progressive adjustment for sociodemographic and CVD risk factors. Our cohort had a mean age (SD) of 73 ± 8 years, 55% women, and a mean TAPSE:PASP ratio of 0.68 ± 0.16. In the unadjusted analysis, increasing tertiles of TAPSE:PASP were associated with younger age, less diabetes, higher estimated glomerular filtration rate, and less antihypertensive medication use. The TAPSE:PASP ratio significantly correlated with both 6MWD and NT-proBNP in the fully adjusted models. A 1-unit increment in TAPSE:PASP was associated with an adjusted 9.9% (4.8% to 15.2%) higher 6MWD, whereas a 1-unit increment in TAPSE:PASP was associated with an adjusted 38.0% (16.0% to 54.2%) lower NT-proBNP. There was a significant gender interaction of the association of TAPSE:PASP ratio and 6MWD, with stronger association seen in women. Among multiethnic older adults free of clinical CVD, the TAPSE:PASP ratio decreased with age, especially in women and was associated with decreased 6MWD and increasing NT-proBNP, the markers of subclinical HF.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Sex Differences in Symptom Complexity and Door-to-Balloon Time in Patients With ST-Elevation Myocardial Infarction.</h4><i>Brush JE, Chaudhry SI, Dreyer RP, D\'Onofrio G, ... Lu Y, Krumholz HM</i><br /><AbstractText>Greater symptom complexity in women than in men could slow acute ST-elevation myocardial infarction (STEMI) recognition and delay door-to-balloon (D2B) times. We sought to determine the sex differences in symptom complexity and their relation to D2B times in 1,677 young and older patients with STEMI using data from the VIRGO and SILVER-AMI studies. Symptom complexity was defined by the number of symptom patterns or phenotypes and average number of symptoms. The numbers of symptom phenotypes were compared in women and men using the Monte Carlo permutation testing. Groups were also compared using the generalized linear regression and logistic regression. The number of symptom phenotypes (244 vs 171, p = 0.02), mean number of symptoms (4.7 vs 4.2, p <0.001), and mean D2B time (114.6 vs 97.8 minutes, p = 0.004) were greater in young women than in young men but were not significantly different in older women compared with older men. The regression analysis did not show a relation between symptom complexity and D2B time overall; although, chest pain was a significant predictor of D2B times, and young women were more likely to report symptoms other than chest pain. Among patients with STEMI, 36% did not receive percutaneous coronary intervention (PCI), which was associated with presentation delay >6 hours. In patients with STEMI with either D2B time ≥90 minutes or no PCI, women had significantly more symptom phenotypes overall and in VIRGO but not in SILVER-AMI. In conclusion, the markers of symptom complexity were not associated with D2B time overall, but more symptom phenotypes in young women were associated with prolonged D2B time or no PCI. In addition, greater frequency of nonchest pain symptoms in young women may have also slowed the recognition of STEMI and D2B times in young women. Further research on symptoms clusters is needed to improve the recognition of STEMIs to improve the D2B times in young women.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Baseline Characteristics and Clinical Outcomes of a Tricuspid Regurgitation Referral Population.</h4><i>Lawlor MK, Ng V, Ahmed S, Dershowitz L, ... Hahn RT, Kodali S</i><br /><AbstractText>Adverse outcomes in tricuspid regurgitation (TR) have been associated with advanced regurgitation severity and right-sided cardiac remodeling, and late referrals for tricuspid valve surgery in TR have been associated with increase in postoperative mortality. The purpose of this study was to evaluate baseline characteristics, clinical outcomes, and procedural utilization of a TR referral population. We analyzed patients with a diagnosis of TR referred to a large TR referral center between 2016 and 2020. We evaluated baseline characteristics stratified by TR severity and analyzed time-to-event outcomes for a composite of overall mortality or heart-failure hospitalization. In total, 408 patients were referred with a diagnosis of TR: the median age of the cohort was 79 years (interquartile range 70 to 84), and 56% were female. In patients evaluated on a 5-grade scale, 10.2% had ≤moderate TR; 30.7% had severe TR; 11.4% had massive TR, and 47.7% had torrential TR. Increasing TR severity was associated with right-sided cardiac remodeling and altered right ventricular hemodynamics. In multivariable Cox regression analysis, New York Heart Association class symptoms, history of heart failure hospitalization, and right atrial pressure were associated with the composite outcome. One-third of patients referred underwent transcatheter tricuspid valve intervention (19%) or surgery (14%); patients who underwent transcatheter tricuspid valve intervention had greater preoperative risk than that of patients who underwent surgery. In conclusion, in patients referred for evaluation of TR, there were high rates of massive and torrential regurgitation and advanced right ventricle remodeling. Symptoms and right atrial pressure are associated with clinical outcomes in follow-up. There were significant differences in baseline procedural risk and eventual therapeutic modality.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Comparison of Stroke and Bleeding Risk Profile in Patients With Atrial Fibrillation and Chronic Kidney Disease.</h4><i>Parada Barcia JA, Raposeiras Roubin S, Abu-Assi E, Erquicia PD, ... González Bermúdez I, Íñiguez-Romo A</i><br /><AbstractText>Clinical decision making on anticoagulation in patients with chronic kidney disease with atrial fibrillation (AF) is challenging. The current strategies are based on small observational studies with conflicting results. This study explores the impact of glomerular filtration rate (GFR) in the embolic-hemorrhagic balance among a large cohort of patients with AF. The study cohort included 15,457 patients diagnosed with AF between January 2014 and April 2020. The risk of ischemic stroke and major bleeding was determined by competing risk regression. During a mean follow-up of 4.29 ± 1.82 years, 3,678 patients (23.80%) died, 850 (5.50%) had an ischemic stroke, and 961 (6.22%) had a major bleeding. The incidence of stroke and bleeding increased as baseline GFR decreased. Interestingly, in GFR <30 ml/min/1.73 m<sup>2</sup>, the bleeding risk was clearly higher than the embolic risk. As GFR decreased, anticoagulation was associated with an increased bleeding risk (subdistribution hazard ratio 1.700, 95% confidence interval [CI] 1.13 to 2.54, p = 0.009 for patients with GFR 30 to 59 ml/min/1.73 m<sup>2</sup> and 2.00, 95% CI 0.77 to 5.21, p = 0.156 for subjects with <30 ml/min/1.73 m<sup>2</sup> compared with those with GFR >60 ml/min/1.73 m<sup>2</sup>, respectively), but it was not associated with a decrease in embolic risk in patients with GFR <30 ml/min/1.73 m<sup>2</sup> (subdistribution hazard ratio 1.91, 95% CI 0.73 to 5.04, p = 0.189) In GFR <30 ml/min/1.73 m<sup>2</sup>, the increase of major bleeding risk was higher than the increase of ischemic stroke risk, with a negative anticoagulation balance (greater increase in bleeding than reduction in embolism).</AbstractText><br /><br />Copyright © 2023.

<div><h4>Arrhythmias in Williams Syndrome.</h4><i>Deitch AM, Giacone HM, Chubb H, Algaze CA, Lechich KM, Collins RT</i><br /><AbstractText>Williams syndrome (WS) is a congenital, multisystem disorder in which 80% of patients have cardiovascular abnormalities. Sudden cardiac death occurs 25 to 100 times more often in WS than in the general population, and cardiac repolarization is abnormal in WS. We sought to determine the prevalence of primary arrhythmias in patients with WS and whether QTc prolongation impacts arrhythmia risk. We retrospectively reviewed all patients with WS with ambulatory electrocardiogram (ECG) monitoring at our institution between October 2017 and January 2022. The primary outcome was the presence of arrhythmia. Predictors pre-determined for analysis included premature ventricular and atrial complex burden (%), degree of QTc change with varying heart rates, intervals and rhythm on 12-lead ECG, age, gender, symptomatology, and clinical and surgical history. A total of 74 patients (55% female, median age 8 years (3, 13) underwent 108 ambulatory monitors. Arrhythmias were present in 9 patients (12%). Within this group of 9 patients, 18/24 serial monitors were abnormal, and 3/9 patients (33%) had >1 arrhythmia type. Older age (p = 0.002) and symptoms (syncope, p = 0.005) were associated with arrhythmias. Arrhythmia was not associated with the degree of structural heart disease. Atrial tachycardia was the most identified arrhythmia (n = 6; 67% of patients with arrhythmias and 8% of the total cohort). The QTc abnormally increased with higher heart rates in all groups. There was a higher number of premature ventricular and atrial complexes per hour in patients with arrhythmias. In conclusion, atrial arrhythmias were the most common arrhythmia in patients with WS and routine ambulatory ECG and intermittent rhythm monitoring are indicated in WS, particularly given the high risk of sudden cardiac death in WS.</AbstractText><br /><br />Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 08 Apr 2023; 195:91-97</small></div>

<div><h4>Hemodynamic Predictors of Stabilization When Using Temporary Mechanical Support for Cardiogenic Shock from Acute on Chronic Heart Failure.</h4><i>Wolfe JD, Deych E, Sintek MA, Schilling JD</i><br /><AbstractText>Cardiogenic shock from acute on chronic heart failure is a lethal condition that frequently requires temporary mechanical circulatory support devices (tMCS) as a bridge to stabilization, durable support, or heart transplantation. However, there are limited data on methods to optimize use of tMCS in this population. We identified patients who received tMCS devices for cardiogenic shock from acute on chronic heart failure at a single center from August 2016 to July 2020. All the patients had invasive hemodynamic data before and immediately after tMCS placement. We classified patients according to whether they showed stabilization or decompensation with tMCS. We then evaluated hemodynamics pre-tMCS, post-tMCS, and the change in hemodynamics with tMCS (∆-tMCS) and assessed their relationship with clinical outcomes. Among 111 patients who received tMCS, 71 stabilized, and 40 decompensated. Post-tMCS hemodynamics were more likely than were pre-tMCS or ∆-tMCS to predict stabilization. Post-tMCS cardiac index >2.1 (area under the curve: 92.2) and cardiac power index >0.3 (area under the curve: 89.6) were the best predictors of stabilization. Patients who decompensated had increased in-hospital all-cause mortality (hazard ratio 3.06 [1.29 to 7.24], p = 0.011), cardiovascular mortality, and increased hospital and intensive care unit length of stay and were less likely to receive left ventricular assist device or heart transplant (hazard ratio 0.56 [0.36 to 0.88], p = 0.01). In conclusion, among patients with cardiogenic shock from acute on chronic heart failure who received tMCS, post-tMCS cardiac index and cardiac power index were highly predictive of stabilization. Those who decompensated had increased mortality, hospital length of stay, and intensive care unit length of stay and were less likely to receive heart replacement therapy.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Mortality, Cardiovascular, and Medication Outcomes in Patients With Myocardial Infarction and Underweight in a Meta-Analysis of 6.3 Million Patients.</h4><i>Lin C, Loke WH, Ng BH, Chin YH, ... Dimitriadis GK, Chew NWS</i><br /><AbstractText>Although most of the current evidence on myocardial infarction focuses on obesity, there is growing evidence that patients who are underweight have unfavorable prognosis. This study aimed to explore the prevalence, clinical characteristics, and prognosis of this population at risk. Embase and Medline were searched for studies reporting outcomes in populations who were underweight with myocardial infarction. Underweight and normal weight were defined according to the World Health Organization criteria. A single-arm meta-analysis of proportions was used to estimate the prevalence of underweight in patients with myocardial infarction, whereas a meta-analysis of proportions was used to estimate the odds ratio of all-cause mortality, medications prescribed, and cardiovascular outcomes. Twenty-one studies involving 6,368,225 patients were included, of whom 47,866 were underweight. The prevalence of underweight in patients with myocardial infarction was 2.96% (95% confidence interval 1.96% to 4.47%). Despite having fewer classical cardiovascular risk factors, patients who were underweight had 66% greater hazard for mortality (hazard ratio 1.66, 95% confidence interval 1.44 to 1.92, p <0.0001). The mortality of patients who were underweight increased from 14.1% at 30 days to 52.6% at 5 years. Nevertheless, they were less likely to receive guideline-directed medical therapy. Relative to subjects with normal weight, Asian populations who were underweight had greater mortality risks than those of their Caucasian counterparts (p = 0.0062). In conclusion, in patients with myocardial infarction, those who were underweight tend to have poorer prognostic outcomes. A lower body mass index is an independent predictor of mortality, which calls for global efforts in addressing this modifiable risk factor in clinical practice guidelines.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Effect of Vigileo/FloTrac System-Guided Aggressive Hydration in Acute Myocardial Infarction Patients to Prevent Contrast-Induced Nephropathy After Urgent Percutaneous Coronary Intervention.</h4><i>Ling W, Jiang Z, Liu K, Zhang H, ... Chen Y, Qian G</i><br /><AbstractText>Tailored hydration strategies appear to provide an effective solution for preventing contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI). The Vigileo/FloTrac system could predict the patients\' fluid responsiveness and tolerance to hydration. This prospective multicenter, randomized controlled, open-label study evaluated the efficacy of aggressive hydration guided by the Vigileo/FloTrac system for CIN prevention in patients with acute myocardial infarction (AMI). This trial enrolled patients with AMI undergoing urgent PCI, and these patients were randomized (1:1) to receive either aggressive hydration guided by Vigileo/FloTrac system (intervention group) or general hydration (control group). Patients with AMI in the intervention group received a loading dose of saline, and the hydration speed was adjusted according to the change of Vigileo/FloTrac index. The primary end point is CIN, which was defined as a >25% or >0.5 mg/100 ml increase in serum creatinine compared with baseline during the first 72 hours after urgent PCI. This trial was registered in ClinicalTrials.gov (NCT04382313). A total of 344 patients with AMI were enrolled and randomized in our trial, and the baseline characteristics, including risk factors of CIN, of the Vigileo/FloTrac-guided hydration group (n = 173) and control group (n = 171) were well balanced (all p >0.05). The total hydration volume in Vigileo/FloTrac-guided hydration group was significantly much more than control group (1,910 ± 600 vs 440 ± 90 ml, p <0.001). The incidence of CIN in the Vigileo/FloTrac-guided hydration group was significantly decreased than that in the control group (12.1% [21/173] vs 22.2% [38/171], p = 0.013). There was not significantly different in the incidence of acute heart failure after PCI (9.2% [16/173] vs 7.6% [13/171], p = 0.583). The incidence of main adverse cardiovascular events in the Vigileo/FloTrac-guided hydration group was lower than that in the control group but without statistically difference (30 events [17.3%] vs 38 events [22.2%], p = 0.256). In conclusion, Vigileo/FloTrac system-guided aggressive hydration could effectively decrease the risk of CIN for patients with AMI undergoing urgent PCI and avoid attack of acute heart failure at the same time.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Suboptimal Cardiology Follow-Up Among Patients With and Without Cancer Hospitalized for Heart Failure.</h4><i>Higgason N, Soroka O, Goyal P, Mahmood SS, Pinheiro LC</i><br /><AbstractText>Many patients hospitalized for heart failure (HF) do not receive recommended follow-up cardiology care, and non-White patients are less likely to receive follow-up than White patients. Poor HF management may be particularly problematic in patients with cancer because cardiovascular co-morbidity can delay cancer treatments. Therefore, we sought to describe outpatient cardiology care patterns in patients with cancer hospitalized for HF and to determine if receipt of follow-up varied by race/ethnicity. SEER (Surveillance, Epidemiology, and End Results) data from 2007 to 2013 linked to Medicare claims from 2006 to 2014 were used. We included patients aged 66+ years with breast, prostate, or colorectal cancer, and preexisting HF. Patients with cancer were matched to patients in a noncancer cohort that included individuals with HF and no cancer. The primary outcome was receipt of an outpatient, face-to-face cardiologist visit within 30 days of HF hospitalization. We compared follow-up rates between cancer and noncancer cohorts, and stratified analyses by race/ethnicity. A total of 2,356 patients with cancer and 2,362 patients without cancer were included. Overall, 43% of patients with cancer and 42% of patients without cancer received cardiologist follow-up (p = 0.30). After multivariable adjustment, White patients were 15% more likely to receive cardiology follow-up than Black patients (95% confidence interval [CI] 1.02 to 1.30). Black patients with cancer were 41% (95% CI 1.11 to 1.78) and Asian patients with cancer were 66% (95% CI 1.11 to 2.49) more likely to visit a cardiologist than their noncancer counterparts. In conclusion, less than half of patients with cancer hospitalized for HF received recommended follow-up with a cardiologist, and significant race-related differences in cardiology follow-up exist. Future studies should investigate the reasons for these differences.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Comparison of Coronary Intravascular Lithotripsy and Rotational Atherectomy in the Modification of Severely Calcified Stenoses.</h4><i>Blachutzik F, Meier S, Weissner M, Schlattner S, ... Nef H, ROTA.Shock Investigators</i><br /><AbstractText>Debulking techniques are often necessary for successful lesion preparation in percutaneous coronary intervention. The aim of this study was to compare plaque modification of severely calcified lesions by coronary intravascular lithotripsy (IVL) with that of rotational atherectomy (RA) using optical coherence tomography (OCT). ROTA.shock was a 1:1 randomized, prospective, double-arm, multicenter noninferiority trial designed to compare final minimal stent area after IVL with RA for lesion preparation in percutaneous coronary interventional treatment of severely calcified lesions. On the basis of OCT acquired before and immediately after IVL or RA in 21 of the 70 patients included, we performed a detailed analysis of the modification of the calcified plaque. After RA and IVL, calcified plaque fractures were present in 14 of the patients (67%), with a significantly greater number of fractures after IVL (3.23 ± 0.49) than after RA (1.67 ± 0.52; p < 0.001). Plaque fractures after IVL were longer than after RA (IVL: 1.67 ± 0.43 mm vs RA: 0.57 ± 0.55 mm; p = 0.01), resulting in a greater total volume of the fractures (IVL: 1.47 ± 0.40 mm<sup>3</sup> vs RA: 0.48 ± 0.27 mm<sup>3</sup>; p = 0.003). Use of RA was associated with a greater acute lumen gain than was use of IVL (RA: 0.46 ± 0.16 mm<sup>2</sup> vs IVL: 0.17 ± 0.14 mm<sup>2</sup>; p = 0.03). In conclusion, we were able to show differences in plaque modification of calcified coronary lesions by OCT: although RA leads to a greater acute lumen gain, IVL induces more and longer fractures of the calcified plaque.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Network Meta-Analysis Comparing Transcatheter, Minimally Invasive, and Conventional Surgical Aortic Valve Replacement.</h4><i>Fong KY, Yap JJL, Chan YH, Ewe SH, ... Tan VH, Ho KW</i><br /><AbstractText>The landscape of aortic valve replacement (AVR) has evolved dramatically over the years, but time-varying outcomes have yet to be comprehensively explored. This study aimed to compare the all-cause mortality among 3 AVR techniques: transcatheter (TAVI), minimally invasive (MIAVR), and conventional AVR (CAVR). An electronic literature search was performed for randomized controlled trials (RCTs) comparing TAVI with CAVR and RCTs or propensity score-matched (PSM) studies comparing MIAVR with CAVR or MIAVR to TAVI. Individual patient data for all-cause mortality were derived from graphical reconstruction of Kaplan-Meier curves. Pairwise comparisons and network meta-analysis were conducted. Sensitivity analyses were performed in the TAVI arm for high risk and low/intermediate risk, as well as patients who underwent transfemoral (TF) TAVI. A total of 27 studies with 16,554 patients were included. In the pairwise comparisons, TAVI showed superior mortality to CAVR until 37.5 months, beyond which there was no significant difference. When restricted to TF TAVI versus CAVR, a consistent mortality benefit favoring TF TAVI was seen (shared frailty hazard ratio [HR] = 0.86, 95% confidence interval [CI] = 0.76 to 0.98, p = 0.024). In the network meta-analysis involving majority PSM data, MIAVR demonstrated significantly lower mortality than TAVI (HR = 0.70, 95% CI = 0.59 to 0.82) and CAVR (HR = 0.69, 95% CI = 0.59 to 0.80); this association remained compared with TF TAVI but with a lower extent of benefit (HR = 0.80, 95% CI = 0.65 to 0.99). In conclusion, the initial short- to medium-term mortality benefit for TAVI over CAVR was attenuated over the longer term. In the subset of patients who underwent TF TAVI, a consistent benefit was found. Among majority PSM data, MIAVR showed improved mortality compared with TAVI and CAVR but less than the TF TAVI subset, which requires validation by robust RCTs.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

It represents a leading cause of hospitalization and still, today, mortality remains high, albeit the progress in treatment strategies. Several factors contribute to the development and progression of HF. Among these, sleep apnea syndrome represents a common but still underestimated factor because its prevalence is substantially higher in patients with HF than in the general population and is related to a worse prognosis. This review summarizes the current knowledge about sleep apnea syndrome coexisting with HF in terms of morbidity and mortality to provide actual and future perspectives about the diagnosis, evaluation, and treatment of this association.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Non-ST-Elevation Coronary Syndromes and Multivessel Disease: A Systematic Review and Meta-Analysis.</h4><i>Kakar H, Groenland FTW, Elscot JJ, Rinaldi R, ... Van Mieghem NM, Diletti R</i><br /><AbstractText>There is lack of evidence regarding the optimal revascularization strategy in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and multivessel disease (MVD). This systematic review and meta-analysis compares the clinical impact of percutaneous coronary intervention (PCI) with that of coronary artery bypass graft surgery (CABG) in this subset of patients. EMBASE, MEDLINE, and Web of Knowledge were searched for studies including patients with NSTE-ACS and MVD who underwent PCI or CABG up to September 1, 2021. The primary end point of the meta-analysis was all-cause mortality at 1 year. The secondary end points were myocardial infarction (MI), stroke, or repeat revascularization at 1 year. The analysis was conducted using the Mantel-Haenszel random-effects model to calculate the odds ratio (OR) with 95% confidence interval (CI). Four prospective observational studies met the inclusion criteria, including 1,542 patients who underwent CABG and 1,630 patients who underwent PCI. No significant differences were found in terms of all-cause mortality (OR 0.91, 95% CI 0.68 to 1.21, p = 0.51), MI (OR 0.78, 95% CI 0.40 to 1.51, p = 0.46), or stroke (OR 1.54, 95% CI 0.55 to 4.35, p = 0.42) between PCI and CABG. Repeat revascularization was significantly lower in the CABG group (OR 0.21, 95% CI 0.13 to 0.34, p <0.00001). In patients presenting with NSTE-ACS and MVD, 1-year mortality, MI, and stroke were similar between patients treated with either PCI or CABG, but the repeat revascularization rate was higher after PCI.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Clinical Outcomes, Resource Utilization, and Treatment Over the Disease Course of Symptomatic Obstructive Hypertrophic Cardiomyopathy in the United States.</h4><i>Desai NR, Sutton MB, Xie J, Fine JT, ... Owens AT, Naidu SS</i><br /><AbstractText>We sought to describe the clinical outcomes, resource utilization, and treatment options for patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM) over the course of their disease. Adults with obstructive HCM who were symptomatic were identified from the IBM MarketScan Commercial and Medicare supplemental database (January 2009 to March 2019). The index date was the initial obstructive HCM diagnosis date. Patients were required to have ≥12-month continuous eligibility before and after the index date. Incidence rates (IRs) and cumulative risk of cardiovascular events, healthcare resource utilization, and pharmacotherapy were assessed after index and compared with matched controls. Among 4,617 eligible patients with obstructive HCM, 2,917 (63.2%, mean age 60, 47.2% women) were symptomatic at index date. The most common cardiovascular events were atrial fibrillation/flutter (IR:1.421 per person-year [PPY], heart failure (IR: 0.895 PPY), and dyspnea (IR:0.797 PPY). Patients incurred higher resource use with frequent tests and monitoring, hospitalizations (0.454 PPY), and emergency room visits (0.611 PPY). The use of pharmacotherapy increased from 61.2% in the 6-month preindex period to 83.9% in the 6-month postindex period and remained stable after diagnosis. These events ranged from 3 to over 60-fold higher compared with controls, with the largest difference observed in arrhythmic events. The majority of patients were symptomatic at the time of obstructive HCM diagnosis, resulting in significantly increased cardiovascular complications and frequent disease monitoring after diagnosis versus controls. In conclusion, healthcare resource utilization was substantial, and these findings suggest a higher clinical and economic burden over the disease course among patients with symptomatic obstructive HCM, despite current treatment.</AbstractText><br /><br />Copyright © 2022.

<div><h4>Persistence on Novel Cardioprotective Antihyperglycemic Therapies in the United States.</h4><i>Nargesi AA, Clark C, Aminorroaya A, Chen L, ... Inzucchi S, Khera R</i><br /><AbstractText>Selected glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT-2is) have cardioprotective effects in patients with type 2 diabetes mellitus (T2D) and elevated cardiovascular risk. Prescription and consistent use of these medications are essential to realizing their benefits. In a nationwide deidentified United States administrative claims database of adults with T2D, the prescription practices of GLP-1RAs and SGLT-2i were evaluated across guideline-directed co-morbidity indications from 2018 to 2020. The monthly fill rates were assessed for 12 months after the initiation of therapy by calculating the proportion of days with consistent medication use. Of 587,657 subjects with T2D, 80,196 (13.6%) were prescribed GLP-1RAs and 68,149 (11.5%) SGLT-2i from 2018 to 2020, representing 12.9% and 11.6% of patients with indications for each medication, respectively. In new initiators, 1-year fill rate was 52.5% for GLP-1RAs and 52.9% for SGLT-2i, which was higher for patients with commercial insurance than those with Medicare Advantage plans for both GLP-1RAs (59.3% vs 51.0%, p <0.001) and SGLT-2i (63.4% vs 50.3%, p <0.001). After adjusting for co-morbidities, there were higher rates of prescription fills for patients with commercial insurance (odds ratio 1.17, 95% confidence interval 1.06 to 1.29 for GLP-1RAs, and 1.59 [1.42 to 1.77] for SGLT-2i); and higher income (odds ratio 1.09 [1.06 to 1.12] for GLP-1RAs, and 1.06 [1.03 to 1.1] for SGLT-2i). From 2018 to 2020, the use of GLP-1RAs and SGLT-2i remained limited to fewer than 1 in 8 patients with T2D and indications, with 1-year fill rates around 50%. The low and inconsistent use of these medications compromises their longitudinal health outcome benefits in a period of expanding indications for their use.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Ischemic and Bleeding Outcomes in Patients Who Underwent Percutaneous Coronary Intervention With Chronic Kidney Disease or Dialysis (from a Japanese Nationwide Registry).</h4><i>Tobe A, Sawano M, Kohsaka S, Ishii H, ... Ikari Y, Murohara T</i><br /><AbstractText>The relation between chronic kidney disease (CKD) and outcomes in patients receiving percutaneous coronary intervention (PCI) is thought to be bidirectional; these patients are at a higher risk of ischemic and bleeding events. From a Japanese nationwide PCI registry, ischemic (cardiovascular death, nonfatal myocardial infarction, or nonfatal ischemic stroke) and bleeding events (fatal or nonfatal major bleeding) 1 year after discharge among patients who had second- or newer-generation drug-eluting stent implantation were analyzed. Patients on oral anticoagulants were excluded. Patients were stratified according to their preprocedural renal function: CKD stages 1 to 2 (estimated glomerular filtration rate [eGFR] ≥60 ml/min/1.73 m<sup>2</sup>), 3 (eGFR 30 to 59), or 4 to 5 (eGFR <30), or those receiving dialysis. Overall, 23,349 patients, including 2,798 patients with CKD 3 to 5 (12.0%) and 1,464 patients on dialysis (6.3%), were investigated. One-year ischemic events were observed in 1.5%, 5.2%, 9.7%, and 5.3% in the CKD stages 1-to-2, 3, 4-to-5, and dialysis groups, respectively; patients with CKD stages 3 or 4 to 5 and those receiving dialysis were associated with higher risks of ischemic events after adjustment of covariates than were patients without CKD. Compared with ischemic events, 1-year bleeding events were low, with incidence rates of 1.5%, 2.0%, 3.4%, and 2.3%, respectively. Furthermore, the presence of CKD or dialysis was not associated with a higher risk of bleeding events after adjustment of covariates. In conclusion, in the contemporary nationwide PCI registry, the presence of CKD and dialysis was independently associated with a higher risk of ischemic events but not with bleeding events, and this suggests a need to alter the models of care delivery in these patients.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Doppler Underestimates Transvalvular Gradient Measured by Catheterization in Patients With Severe Aortic Stenosis.</h4><i>Takamatsu K, Yamano T, Zen K, Takahara M, ... Yaku H, Matoba S</i><br /><AbstractText>We sought to clarify characteristics of patients with severe aortic stenosis (AS) in whom transvalvular mean pressure gradient (MPG) was underestimated with Doppler compared with catheterization. Study subjects included 127 patients with severe AS who underwent transcatheter aortic valve implantation. Between subjects with Doppler MPG underestimation ≥10 mm Hg (group U) and those without (group C), we retrospectively compared echocardiographic parameters and aortic valve calcification score using the Agatston method. Despite a strong correlation (r<sub>S</sub> = 0.88) and small absolute difference (2.1 ± 10.1 mm Hg) between Doppler and catheter MPG, 27 patients (21%) were in group U. Among 48 patients with catheter MPG ≥60 mm Hg, 10 patients (21%) revealed Doppler MPG of 40 to 59 mm Hg, suggesting they had been misclassified as having severe AS instead of very severe AS. According to the guidelines, indication of valve replacement for patients without symptoms should be considered for very severe AS but not for severe AS. Therefore, sole reliance on Doppler MPG could cause clinical misjudgments. Group U had larger relative wall thickness (median [interquartile range: 0.60 [0.50 to 0.69] vs 0.53 [0.46 to 0.60], p = 0.003) and higher calcification score (3,024 [2,066 to 3,555] vs 1,790 [1,293 to 2,501] arbitrary units, p <0.001). Both calcification score (per 100 arbitrary unit increment, odds ratio 1.10, 1.04 to 1.17, p = 0.002) and relative wall thickness (per 0.05 increment, odds ratio 1.29, 95% confidence interval 1.05 to 1.60, p = 0.02) were independently associated with Doppler underestimation. In conclusion, Doppler might underestimate transvalvular gradient compared with catheterization in patients with severe AS who have heavy valve calcification and prominent concentric remodeling left ventricular geometry.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>A Systematic Review and Meta-Analysis of Prevalence and Outcomes of Cardiac Metastasis of Neuroendocrine Malignancies.</h4><i>Hamza M, Manasrah N, Patel NN, Sattar Y, Patel B</i><br /><AbstractText>Neuroendocrine tumors (NETs) are a rare group of malignancies which are aggressive and widely metastatic. Cardiac metastases (CMs) are rarely reported because of NET. We aim to analyze the available literature to study the proportional prevalence of CM because of NET and its location and effect on the ejection fraction (EF) and survival rate. Our search strategy and meta-analysis are in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) AMSTAR-2 (Assessing the methodological quality of systematic Reviews-2) Guidelines. A literature search was conducted on MEDLINE (EMBASE and PubMed) for randomized clinical trials, pilot trials, and retrospective and prospective studies. Statistical analysis was performed using the CRAN-R software (https://CRAN.R-project.org/doc/FAQ/R-FAQ.html). The quality assessment of the included articles was performed using the Cochrane Risk of Bias and Newcastle-Ottawa Scale. A total of 16,685 patients were included in the study. The mean age of patients included in the study was 61.28 ± SD 9.89 years. Of these, 257 patients had a total of 283 CM. Metastasis was mainly located in the left ventricle with a pooled proportion of 0.48, 95% confidence interval (CI) 0.4 to 0.56, pericardium: 0.34, 95% CI 0.19 to 0.53, right ventricle 0.28, 95% CI 0.16 to 0.44, interventricular septum 0.25, 95% CI 0.16 to 0.37, left atrium 0.1, 95% CI 0.03 to 0.26 and right atrium 0.05, 95% CI 0.01 to 0.20. Decrease in EF at the time of CM diagnosis was the effect most consistently reported in patients with CM. Pooled mean survival was 35.89, 95% CI 8.27 to 155.68 months after the diagnosis of CM. CM due to NET was <2% and the left ventricle is the most common metastatic location, followed by the pericardium. Decreased EF was the most common clinical picture observed. Further studies are needed to analyze the clinical impact of NET CM.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Association of Serum Calcium and Phosphate With Incident Cardiovascular Disease in Patients With Hypoparathyroidism.</h4><i>Kaul S, Ayodele O, Chen K, Cook EE, ... Rejnmark L, Gosmanova EO</i><br /><AbstractText>The pathophysiological basis for the increased incidence of cardiovascular disease in patients with chronic hypoparathyroidism is poorly understood. To evaluate associations between levels of albumin-corrected serum calcium, serum phosphate, and calcium-phosphate product with the odds of developing cardiovascular events in patients with chronic hypoparathyroidism with ≥1 calcitriol prescription, we conducted a retrospective nested case-control study of patients who developed a cardiovascular event and matched controls without an event. The primary outcome was the instance of cardiovascular events. An electronic medical record database was used to identify 528 patients for the albumin-corrected serum calcium analysis and 200 patients for the serum phosphate and calcium-phosphate product analyses. Patients with ≥67% of albumin-corrected serum calcium measurements outside the study-defined 2.00 to 2.25 mmol/L (8.0 to 9.0 mg/100 ml) range had 1.9-fold higher odds of a cardiovascular event (adjusted odds ratio, 95% confidence interval 1.89, 1.10 to 3.25) compared with patients with <33% of calcium measurements outside the range. Likewise, patients with any serum phosphate measurements above 0.81 to 1.45 mmol/L (2.5 to 4.5 mg/100 ml) had 3.3-fold higher odds (3.26; 1.24 to 8.58), and those with any calcium-phosphate product measurements above 4.40 mmol<sup>2</sup>/L<sup>2</sup> (55 mg<sup>2</sup>/dL<sup>2</sup>) had 4.8-fold higher odds of a cardiovascular event (95% confidence interval 1.36 to 16.81) compared with patients with no measurements above these ranges. In adult patients with chronic hypoparathyroidism, a cardiovascular event was more likely in those with a higher proportion of albumin-corrected serum calcium measurements outside 2.00 to 2.25 mmol/L (8.0 to 9.0 mg/100 ml) or any serum phosphate and any calcium-phosphate product measurements above the normal population range.</AbstractText><br /><br />Copyright © 2023 The Authors.

<div><h4>Meta-Analysis of Long-Term (>1 Year) Cardiac Outcomes of Peripartum Cardiomyopathy.</h4><i>Koerber D, Khan S, Kirubarajan A, Spivak A, ... Sobel M, Harris K</i><br /><AbstractText>Peripartum cardiomyopathy is the development of heart failure toward the end of pregnancy or in the months after delivery in the absence of other attributable causes, with left ventricular systolic dysfunction and a left ventricular ejection fraction (LVEF) generally <45%. Given that patients are relatively young at the time of diagnosis, this study was performed to summarize current evidence surrounding the long-term cardiac outcomes. MEDLINE, Embase, Cochrane CENTRAL, and CINAHL were searched for original studies that reported long-term (>1 year) patient outcomes. Of the 3,144 total records identified, 62 studies involving 4,282 patients met the selection criteria. The mean LVEF was 28% at diagnosis and 47% at the time of the last follow-up. Approximately half of the patients achieved myocardial recovery (47%), most commonly defined as an LVEF >50% (n = 21). The prevalence of implantable cardioverter-defibrillator use, left ventricular assist device implantation, and heart transplantation was 12%, 7%, and 11%, respectively. The overall all-cause mortality was 9%, and despite having more cardiovascular risk factors, patients residing in high-income countries had superior outcomes, including reduced rates of mortality.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>In-hospital Outcomes of Patients With and Without Previous Coronary Artery Bypass Graft Surgery Who Present With a Non-ST-Segment Elevation Myocardial Infarction.</h4><i>Dhaduk N, Xia Y, Feit F, Mamas M, ... Rao SV, Bangalore S</i><br /><AbstractText>The clinical course of patients with a previous coronary artery bypass graft surgery (CABG) presenting with non-ST-elevation myocardial infarction (NSTEMI) is not well defined. We aimed to compare the management and outcomes of patients with and without previous CABG who present with an NSTEMI. Patients hospitalized with an NSTEMI between 2002 and 2018 were identified from the National Inpatient Sample. The baseline characteristics and outcomes of patients with and without a previous CABG were compared. The outcomes included the rates of invasive procedures (defined as coronary angiography, percutaneous coronary intervention [PCI], or CABG), and its individual components, and in-hospital mortality. A total of 1,445,545 cases of NSTEMI were found, of which 133,691 (9.3%) had a previous CABG. Patients with a previous CABG were older (72.4 vs 68.6 years, p <0.001), more likely men (68.8% vs 56.9%, p <0.001), and of White race (79.7% vs 74.8%, p <0.001). The previous CABG cohort had lower rates of invasive procedures (50.4% vs 65.6%, p <0.001), PCI (23.7% vs 32.0%, p <0.001), or CABG (1.2% vs 10.6%; p <0.001) in the unmatched analysis. The results were consistent in the propensity score-matched analysis with the previous CABG group less likely to receive any invasive procedures (odds ratio [OR] 0.48, 95% confidence interval [CI] 0.47 to 0.49), including coronary angiography (OR 0.54, 95% CI 0.53 to 0.55), PCI (OR 0.66, 95% CI 0.64 to 0.67), or repeat CABG (OR 0.11, 95% CI 0.10 to 0.12). Moreover, the risk of in-hospital mortality was higher in the previous CABG group (OR 1.15, 95% CI 1.10 to 1.21). In the subset of patients who were revascularized in both groups, this excess mortality was no longer observed (OR 0.82, 95% CI 0.66 to 1.03). In conclusion, a previous CABG in patients who present with NSTEMI is associated with lower rates of invasive procedures and revascularization and higher in-hospital mortality than patients without a previous CABG.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Impact of Chronic Heart Failure on Acute Pulmonary Embolism in-Hospital Outcomes (From a Contemporary Study).</h4><i>Quintero-Martinez JA, Dangl M, Uribe J, Vasquez MA, ... Maning J, Colombo R</i><br /><AbstractText>There is a paucity of evidence on the impact of chronic heart failure (HF) on acute pulmonary embolism (PE) hospitalization outcomes. The aim of this study was to evaluate the in-hospital outcomes of patients with chronic HF and acute PE. A total of 1,391,145 hospitalizations with acute PE from the National Inpatient Sample Database from 2011 to 2019 were included. The database was queried for relevant International Classification of Diseases, Ninth and Tenth Revisions procedural and diagnostic codes. Baseline characteristics and in-hospital outcomes for patients with acute PE were compared in patients with and without a history of chronic HF. Multivariate logistic regression analyses were performed, adjusting for age, race, gender, and statistically significant co-morbidities between cohorts. A p value <0.001 was considered significant. Overall, the mean age was 65.2±16 years; 50.9% of patients were women, and 230,875 patients (16.6%) had chronic HF. The patients in the chronic HF cohort were predominantly older (mean age 69.0 vs 61.4 years) and male (49.9% vs 48.3%). In the multivariate model, chronic HF was associated with increased all-cause mortality (odds ratio [OR] 1.6, 95% confidence interval [CI], 1.57 to 1.63, 10.4% vs 5.7%), acute respiratory distress (OR 1.7, 95% CI 1.70 to 1.74, 39.5% vs 22.1%), cardiac arrest (OR 1.4, 95% CI 1.40 to 1.49, 3.9% vs 2.2%), and cardiogenic shock (OR 3.0, 95% CI 2.85 to 3.06, 4.2% vs 1.2%). All p values were <0.001. In conclusion, patients with PE and chronicHF are associated with increased in-hospital complications compared with patients with PE and without chronic HF. Prospective studies are needed to evaluate optimal management strategies in this population at high risk.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Disability-Adjusted Life-Years After Adult In-Hospital Cardiac Arrest in the United States.</h4><i>Coute RA, Nathanson BH, Kurz MC, Mader TJ, Jackson EA, American Heart Association\'s Get With The Guidelines—Resuscitation Investigators</i><br /><AbstractText>We sought to estimate disability-adjusted life-years (DALYs) because of adult in-hospital cardiac arrest (IHCA) and to compare IHCA DALY to other leading causes of death and disability in the United States. DALY were calculated as the sum of years of life lost and years lived with disability. The years of life lost were calculated using all adult IHCA with complete data from the American Heart Association Get With The Guidelines-Resuscitation database for 2015 to 2019. Cerebral performance category scores and published disability weights were used to estimate the years lived with disability for survivors. The cohort\'s DALY were extrapolated to a national level to estimate the total United States DALY and were compared with a published ranking of the leading causes of DALY in the United States for 2018. Data were reported as DALY total and rate per 100,000. A total of 99,897 IHCA were included from 329 hospitals. The total IHCA DALY increased from 2,208,310 in 2015 to 2,225,722 in 2019. A modest decrease in the DALY rate was observed from 689 per 100,000 in 2015 to 678 per 100,000 in 2019. In 2018, the rate of IHCA DALY were 728 per 100,000, which represented the 11th leading cause of DALY. When combined with out-of-hospital cardiac arrest (1,322 per 100,000), sudden cardiac arrest (2,050 per 100,000) was found the be the 2nd leading cause of DALY after ischemic heart disease (2,681 per 100,000) in 2018. In conclusion, adult IHCA is a leading cause of DALY in the United States and has increased over time because of the expansion of the Get With The Guidelines-Resuscitation database.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Meta-Analysis on the Efficacy of High-Dose Statin Loading Before Percutaneous Coronary Intervention in Reducing No-Reflow Phenomenon in Acute Coronary Syndrome.</h4><i>Anayat S, Majid K, Nazir HS, Nizami AA, ... Ullah I, Asghar MS</i><br /><AbstractText>Currently, guidelines recommend the uptake of high-dose statins before and after percutaneous coronary intervention (PCI) in patients with acute coronary syndrome. However, the association of high-dose statins with the incidence of the no-reflow phenomenon remains unclear. This study aimed to review the evidence of preprocedural high-dose statin therapy to reduce no-reflow incidence after PCI. PubMed, Embase, and Google Scholar were searched from inception until May 2022 for studies comparing high-dose statins with low-dose or no statin therapy before PCI. Studies reporting the no-reflow phenomenon were shortlisted. The National Institutes of Health tool for randomized and cohort studies was used to assess the quality of included studies. A random-effects model was used to derive odds ratios (ORs) and their corresponding 95% confidence intervals (CIs). A total of 11 studies were included, with a population of 4,294 patients. The use of high-dose statins before PCI significantly reduced postprocedural no-reflow (OR 0.51, 95% CI 0.35 to 0.74, p = 0.0005, I<sup>2</sup> = 32%). A total of 7 studies included patients who underwent PCI without previous use of statins. A significant decrease in overall no-reflow events was observed with high-intensity statin treatment versus low-intensity statin/placebo (OR 0.55, 95% CI 0.34 to 0.88, p = 0.01, I<sup>2</sup> = 25%) among patients who were statin naive. Acute high-dose statin therapy before PCI significantly reduces the hazard of post-PCI no-reflow events in patients with acute coronary syndrome. Our results encourage the routine use of statins before PCI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Impact of Biopsy Proven Liver Fibrosis on Patients Undergoing Evaluation and Treatment for Advanced Heart Failure Surgical Therapies.</h4><i>Goyal A, Dalia T, Ranka S, Sauer AJ, ... Gupta B, Haglund NA</i><br /><AbstractText>There is a paucity of data regarding the impact of liver fibrosis on patients with stage D heart failure (HF). We conducted a retrospective study (January 1, 2017 to December 12, 2020) in patients with stage D HF who underwent liver biopsy as part of their advanced HF therapy evaluation. Baseline characteristics and 1-year outcomes were compared between no- or mild-to-moderate-fibrosis (grade 0 to 2) and advanced-fibrosis (grade 3 to 4) groups. Of 519 patients with stage D HF, 136 who underwent liver biopsy (113 [83%] no or mild-to-moderate fibrosis and 23 [17%] advanced fibrosis) were included. A total of 71 patients (52%) received advanced HF therapies (23 heart transplantation, 48 left ventricular assist devices). One-year mortality was higher among patients with advanced fibrosis (52% vs 18%, p <0.001). Further subgroup analysis suggested a trend toward increased 1-year mortality among patients with advanced fibrosis who underwent advanced therapies (37% vs 13%, p = 0.09). There was a trend of lower likelihood of receiving advanced HF therapies in the advanced-fibrosis group, only 1 heart transplantation and 7 left ventricular assist devices, but it did not reach statistical significance (35% vs 56%, p = 0.06). After adjustment for confounders, degree of liver fibrosis was an independent predictor of mortality (odds ratio 6.2; 95% 1.27 to 30.29, p = 0.02). We conclude that advanced liver fibrosis is common among patients with stage D HF who undergo evaluation for advanced HF surgical therapies and significantly increases 1-year mortality. Further larger studies are needed to support our findings.</AbstractText><br /><br />Copyright © 2023. Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 20 Mar 2023; 194:46-55</small></div>

<div><h4>The Quality and Safety of Sedation and Monitoring in Adults Undergoing Nonoperative Transesophageal Echocardiography.</h4><i>Kersey CB, Lele AV, Johnson MN, Pattock AM, ... Jobarteh S, Kwon Y</i><br /><AbstractText>Sedation is an essential component of the transesophageal echocardiography (TEE) procedure for patient comfort. The use and the clinical implications of cardiologist-supervised (CARD-Sed) versus anesthesiologist-supervised sedation (ANES-Sed) are unknown. We reviewed nonoperative TEE records from a single academic center over a 5-year period and identified CARD-Sed and ANES-Sed cases. We evaluated the impact of patient co-morbidities, cardiac abnormalities on transthoracic echocardiogram, and the indication for TEE on sedation practice. We analyzed the use of CARD-Sed versus ANES-Sed in light of institutional guidelines; the consistency in the documentation of preprocedural risk stratification; and the incidence of cardiopulmonary events, including hypotension, hypoxia, and hypercarbia. A total of 914 patients underwent TEE, with 475 patients (52%) receiving CARD-Sed and 439 patients (48%) receiving ANES-Sed. The presence of obstructive sleep apnea (p = 0.008), a body mass index of >45 kg/m<sup>2</sup> (p <0.001), an ejection fraction of <30% (p <0.001), and pulmonary artery systolic pressure of more than 40 mm Hg (p = 0.015) were all associated with the use of ANES-Sed. Of the 178 patients (19.5%) with at least 1 caution to nonanesthesiologist-supervised sedation by the institutional screening guideline, 65 patients (36.5%) underwent CARD-Sed. In the ANES-Sed group, where intraprocedural vital signs and medications were documented in all cases, hypotension (n = 91, 20.7%), vasoactive medication use (n = 121, 27.6%), hypoxia (n = 35, 8.0%), and hypercarbia (n = 50, 11.4%) were noted. This single-center study revealed that 48% of the nonoperative TEE used ANES-Sed over 5 years. Sedation-related hemodynamic changes and respiratory events were not infrequently encountered during ANES-Sed.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Contemporary Trends in Acute Myocardial Infarction in the American Indian/Alaska Native U.S. Population, 2000 to 2018.</h4><i>Stouffer JA, Hendrickson MJ, Arora S, Vavalle JP</i><br /><AbstractText>Coronary heart disease is disproportionately prevalent in the American Indian/Alaska Native (AI/AN) population. As care for acute myocardial infarction (AMI) continues to advance, equitable distribution and access for the AI/AN population is essential. Primary AMI hospitalizations for adults ≥18 years of age were identified from the Healthcare Cost and Utilization Project National Inpatient Sample from 2000 to 2018. Related co-morbidities, procedures of interest, and in-hospital mortality were also identified. These rates were stratified by race then trended over years using Poisson regression. Overall, 9,904,714 weighted hospitalizations for primary AMI were identified. From 2000 to 2018, AI/AN adults had relatively high rates of primary AMI hospitalization, second only to non-Hispanic (NH) White adults. The AMI rate increased from 14.0/1,000 to 16.1/1,000 among AI/AN adults, remaining higher than NH Black adults (12.1/1,000 to 13.0/1,000) and Hispanic adults (10.3/1,000 and 12.7/1,000) and becoming increasingly closer to NH White adults (25.1/1,000 to 20.0/1,000) (p <0.001 for each). AI/AN adults presented 5 years earlier than their NH White counterparts (64 vs 69 years old; p <0.001). In-hospital mortality was approximately 5% for all race categories and decreased in all groups but decreased at a much greater rate for NH White, NH Black and Hispanic adults (0.2% per year) compared with AI/AN adults (0.08% per year; p <0.001 for each comparison). Rates of coronary angiography and percutaneous coronary intervention increased in all groups, but coronary artery bypass graft utilization increased only in AI/AN adults (from 7% to 10%, p <0.001). In conclusion, from 2000 to 2018, AI/AN adults had a high rate of AMI hospitalizations (second only to NH White adults) that increased significantly over time. AI/AN adults were 5 years younger than their NH White counterparts at index AMI hospitalization. Care during these hospitalizations was similar among all racial groups, and in-hospital mortality decreased for all groups, albeit to a lesser degree among AI/AN adults. This study highlights the need for improved access to outpatient primary AMI prevention in the AI/AN population.</AbstractText><br /><br />Published by Elsevier Inc.<br /><br /><small>Am J Cardiol: 17 Mar 2023; 194:34-39</small></div>

<div><h4>Cancer and Myocardial Infarction in Women.</h4><i>Panday P, Hausvater A, Pleasure M, Smilowitz NR, Reynolds HR</i><br /><AbstractText>Women who present with myocardial infarction (MI) are more likely to be diagnosed with nonobstructive coronary arteries (MINOCAs), spontaneous coronary artery dissection (SCAD), and takotsubo syndrome (TS) than men. Malignancy may predispose to MI and TS through shared risk factors and inflammatory mediators. This study aimed to determine the prevalence of cancer in women presenting with clinical syndrome of MI and the association between cancer and mechanism of MI presentation. Among 520 women with MI who underwent coronary angiography at NYU Langone Health from March 2016 to March 2020 or September 2020 to September 2021, 122 (23%) had a previous diagnosis of cancer. Patients with cancer were older at MI presentation but had similar co-morbidity to those without a cancer history. The most common cancers were breast (39%), gynecologic (15%), and gastrointestinal (13%). Women with cancer history were more likely to have TS (17% vs 11% without cancer history p = 0.049). Among women with a final diagnosis of MI, the type of MI (MINOCA, MI-coronary artery disease, or SCAD) was not significantly different between groups (p = 0.374). History of cancer was present in nearly a quarter of women presenting with MI and was associated with a greater likelihood of TS than MI. MINOCA and SCAD were not more common among women with a cancer history.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Patterns of Care and Outcomes of Ambulatory Endovascular Interventions in Lower Extremity Peripheral Arterial Disease.</h4><i>Chaturvedi A, Castro-Dominguez Y, Gertz ZM, Lawson BD, ... Kochar A, Guha A</i><br /><AbstractText>Lower extremity endovascular intervention (LE-EVI) is gaining popularity as the primary treatment modality for patients with symptomatic peripheral artery disease refractory to noninvasive management. We examined the contemporary patterns of care, regional variation, and outcomes of ambulatory LE-EVI in the United States. The National Ambulatory Surgery Sample was analyzed to identify 266,563 records with peripheral artery disease and LE-EVI between January 1, 2016 and December 31, 2017. The mean age of the study cohort was 68.9 years and 40.5% were women. The majority of the endovascular interventions were performed at large (58.1%), urban teaching (64.1%), private not-for-profit (76.8%) centers, and the southern region accounted for most cases (43%). Periprocedural major adverse renal and cardiovascular events and other complications were 0.5% and 3.3%, respectively. Most patients (97.6%) were discharged home after the procedure. Age, female gender, uncontrolled hypertension, ischemic heart disease, heart failure, arrhythmia, chronic kidney disease, malnutrition, non-Medicare insurance, private for-profit, urban teaching facilities, and southern and midwest regions were associated with higher odds of major adverse renal and cardiovascular events. The mean charges per patient encounter were $56,500, with significant differences across various patient and facility characteristics. In conclusion, our study demonstrates the use, patterns of care, financial aspect, and overall safety of ambulatory LE-EVIs in a real-world setting.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Three-Year Outcomes of Balloon-Expandable Transcatheter Aortic Valve Implantation According to Annular Size.</h4><i>Abushouk AI, Spilias N, Isogai T, Kansara T, ... Yun J, Kapadia S</i><br /><AbstractText>Data on the association between annular size and transcatheter aortic valve implantation (TAVI) outcomes beyond 1 year are limited. The present study assessed the association between the aortic annulus size and TAVI clinical and hemodynamic outcomes at 3 years of follow-up. Patients were classified according to the aortic annulus size as having small, intermediate, and large annuli (size <400, 400 to 574, and ≥575 mm<sup>2</sup>, respectively). The co-primary endpoints were all-cause mortality and heart failure hospitalization. Further, the changes in hemodynamic outcomes over the follow-up period (median 37, interquartile range: 26 to 45 months) were assessed. The present analysis included 850 patients, with 182 patients (21.4%), 538 patients (63.3%), and 130 patients (15.3%) in the small, intermediate, and large-sized aortic annulus groups, respectively. The groups had comparable age and pre-TAVI pressure gradients; however, patients with small annuli had higher Society of Thoracic Surgeons risk scores. Adjusted Cox regression analysis showed that compared to patients with intermediate-sized annuli, patients with small and large annuli had similar all-cause mortality (hazard ratio [HR] = 1.11, 95% confidence interval [CI] 0.72 to 1.69 and HR = 0.74, 95% CI 0.48 to 1.16, respectively) and heart failure hospitalization rates (HR = 0.96, 95% CI 0.55 to 1.69 and HR = 1.26, 95% CI 0.73 to 2.17, respectively). However, patients with small annuli had consistently higher mean and peak pressure gradients and a higher risk of patient-prosthesis mismatch. The risks of moderate-to-severe regurgitation and structural valve deterioration were similar between the three groups. In conclusion, although patients with small annuli had higher transvalvular gradients, there was no significant association between the aortic annulus size and TAVI clinical outcomes at 3 years of follow-up. Future studies should compare the performance of transcatheter valve types in patients with different aortic annulus sizes.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Racial Differences in Fatal Out-of-Hospital Coronary Heart Disease and the Role of Income in the Atherosclerosis Risk in Communities Cohort Study (1987 to 2017).</h4><i>Islek D, Alonso A, Rosamond W, Guild CS, ... Naimi AI, Vaccarino V</i><br /><AbstractText>Black patients have higher incident fatal coronary heart disease (CHD) rates than do their White counterparts. Racial differences in out-of-hospital fatal CHD could explain the excess risk in fatal CHD among Black patients. We examined racial disparities in in- and out-of-hospital fatal CHD among participants with no history of CHD, and whether socioeconomic status might play a role in this association. We used data from the ARIC (Atherosclerosis Risk in Communities) study, including 4,095 Black and 10,884 White participants, followed between 1987 and 1989 until 2017. Race was self-reported. We examined racial differences in in- and out-of-hospital fatal CHD with hierarchical proportional hazard models. We then examined the role of income in these associations, using Cox marginal structural models for a mediation analysis. The incidence of out-of-hospital and in-hospital fatal CHD was 1.3 and 2.2 in Black participants, and 1.0 and 1.1 in White participants, respectively, per 1,000 person-years. The gender- and age-adjusted hazard ratios comparing out-of-hospital and in-hospital incident fatal CHD in Black with that in White participants were 1.65 (1.32 to 2.07) and 2.37 (1.96 to 2.86), respectively. The income-controlled direct effects of race in Black versus White participants decreased to 1.33 (1.01 to 1.74) for fatal out-of-hospital and to 2.03 (1.61 to 2.55) for fatal in-hospital CHD in Cox marginal structural models. In conclusion, higher rates of fatal in-hospital CHD in Black participants than in their White counterparts likely drive the overall racial differences in fatal CHD. Income largely explained racial differences in both fatal out-of-hospital CHD and fatal in-hospital CHD.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Comparison of Long-Term Clinical Outcomes of Elective Percutaneous Coronary Intervention Between Complex and High-risk Intervention in Indicated Patients (CHIP) versus Non-CHIP.</h4><i>Fujimoto Y, Sakakura K, Jinnouchi H, Taniguchi Y, ... Wada H, Fujita H</i><br /><AbstractText>Recently, there has been a growing interest in complex and high-risk intervention in indicated patients (CHIP) in the contemporary percutaneous coronary intervention (PCI). CHIP is composed of the following 3 factors: (1) patient factors, (2) complicated heart disease, and (3) complex PCI. However, there are few studies that investigated the long-term outcomes of CHIP-PCI. The purpose of this study was to compare the incidence of long-term major adverse cardiovascular events (MACEs) among the definite CHIP, possible CHIP, and non-CHIP groups in complex PCI. We included 961 patients and divided them into the definite CHIP (n = 129), the possible CHIP (n = 369), and the non-CHIP groups (n = 463). During the median follow-up duration of 573 days (quartile 1:226 days to quartile 3:1,165 days), a total of 189 MACE were observed. The incidence of MACE was highest in the definite CHIP group, followed by the possible CHIP group, and lowest in the non-CHIP group (p = 0.001). Definite CHIP (vs non-CHIP: odds ratio 3.558, 95% confidence interval 2.249 to 5.629, p <0.001) and possible CHIP (vs non-CHIP: odds ratio 2.260, 95% confidence interval 1.563 to 3.266, p <0.001) were significantly associated with MACE after controlling for confounding factors. Among CHIP factors, active malignancy, pulmonary disease, hemodialysis, unstable hemodynamics, left ventricular ejection fraction, and valvular disease were significantly associated with MACE. In conclusion, the incidence of MACE in complex PCI was highest in the definite CHIP group, followed by the possible CHIP group, and lowest in the non-CHIP group. The concept of CHIP should be recognized to predict the long-term MACE in patients who undergo complex PCI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>A Systematic Review of Periprocedural Risk Prediction Scores in Chronic Total Occlusion Percutaneous Coronary Intervention.</h4><i>Simsek B, Rempakos A, Kostantinis S, Karacsonyi J, ... Burke MN, Brilakis ES</i><br /><AbstractText>Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is associated with high incidence of complications. We queried PubMed and the Cochrane Library (last search: October 26, 2022) for CTO PCI-specific periprocedural complication risk scores. We identified 8 CTO PCI-specific risk scores: (1) Angiographic coronary artery perforation (OPEN-CLEAN [Outcomes, Patient Health Status, and Efficiency iN (OPEN) Chronic Total Occlusion (CTO) Hybrid Procedures - CABG, Length (occlusion), EF <50%, Age, CalcificatioN] perforation, c-statistic 0.75): previous coronary artery bypass graft surgery, occlusion length 20 to 60 mm or ≥60 mm, left ventricular ejection fraction (LVEF) <50%, age 50 to 70 years or ≥70 years, heavy calcification. (2) Major adverse cardiovascular events (MACE) (PROGRESS-CTO complication, c-statistic 0.76): age >65 years, lesion length ≥23 mm, retrograde strategy, and (3) MACE (PROGRESS-CTO MACE, c-statistic 0.74): age ≥65 years, female gender, moderate/severe calcification, blunt/no stump, anterograde dissection and re-entry (ADR) or retrograde strategy. (4) All-cause mortality (PROGRESS-CTO mortality, c-statistic 0.80): age ≥65, moderate/severe calcification, LVEF ≤45%, ADR or retrograde strategy. (5) Perforation requiring pericardiocentesis (PROGRESS-CTO pericardiocentesis, c-statistic 0.78): age ≥65 years, moderate/severe calcification, female gender, ADR or retrograde strategy. (6) Acute myocardial infarction (PROGRESS-CTO acute myocardial infarction, c-statistic 0.72): previous coronary artery bypass graft surgery, atrial fibrillation, blunt/no stump. (7) Perforation requiring any treatment (PROGRESS-CTO perforation, c-statistic 0.74): age ≥65 years, moderate/severe calcification, blunt/no stump, ADR, or retrograde strategy. (8) Contrast-induced acute kidney injury (c-statistic 0.84): age ≥75, LVEF <40%, serum creatinine >1.5 mg/100 ml, serum albumin ≤30, 30<albumin≤40 or >40 g/L. There are 8 CTO PCI periprocedural risk scores that may facilitate risk assessment and procedural planning in patients who underwent CTO PCI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Acute Coronary Syndrome After Transcatheter Aortic Valve Implantation (Results from Over 40,000 Patients).</h4><i>Ogami T, Kliner DE, Toma C, Sanon S, ... Yousef S, Sultan I</i><br /><AbstractText>Acute coronary syndrome (ACS) encompasses a broad category of presentations from unstable angina to ST-elevation myocardial infarctions. Most patients undergo coronary angiography upon presentation for diagnosis and treatment. However, the ACS management strategy after transcatheter aortic valve implantation (TAVI) may be complicated because of challenging coronary access. The National Readmission Database was reviewed to identify all patients who were readmitted with ACS within 90 days after TAVI between 2012 and 2018. Their outcomes were described between patients who were readmitted with ACS (ACS group) and without (non-ACS group). A total of 44,653 patients were readmitted within 90 days after TAVI. Among them, 1,416 patients (3.2%) were readmitted with ACS. The ACS group had a higher prevalence of men, diabetes, hypertension, congestive heart failure, peripheral vascular disease, and a history of percutaneous coronary intervention (PCI). In the ACS group, 101 patients (7.1%) developed cardiogenic shock, whereas 120 patients (8.5%) developed ventricular arrhythmias. Overall, 141 patients (9.9%) in the ACS group died during readmissions (vs 3.0% in the non-ACS group, p <0.001). Among the ACS group, PCI was performed in 33 (5.9%), whereas coronary bypass grafting was performed in 12 (0.82%). The factors associated with ACS readmission included a history of diabetes, congestive heart failure, chronic kidney disease, and PCI, and nonelective TAVI. Coronary artery bypass grafting was an independent factor related to in-hospital mortality during ACS readmission (odds ratio 11.9, 95% confidence interval 2.18 to 65.4, p = 0.004), whereas PCI was not (odds ratio 0.19, 95% confidence interval 0.03 to 1.44, p = 0.11). In conclusion, patients readmitted with ACS have significantly higher mortality compared with those readmitted without ACS. History of PCI is an independent factor associated with ACS after TAVI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Predictors of Maintenance of Sinus Rhythm After Radiofrequency Catheter Ablation for Long-Standing Persistent Atrial Fibrillation.</h4><i>Ukita K, Egami Y, Kawanami S, Sugae H, ... Nishino M, Tanouchi J</i><br /><AbstractText>Little has been reported on the predictors of maintenance of sinus rhythm (SR) after radiofrequency catheter ablation (RFCA) for long-standing persistent atrial fibrillation (AF). We enrolled 151 patients with long-standing persistent AF (defined as AF lasting more than 12 months) who underwent an initial RFCA between October 2014 and December 2020 in our hospital. These patients were categorized into 2 groups on the basis of the absence and presence of the late recurrence (LR, defined as a recurrence of atrial tachyarrhythmia between 3 and 12 months after RFCA): SR group and LR group. The SR group comprised 92 patients (61%). In the univariate analysis, there were significant differences in gender and preprocedural average heart rate (HR) between the 2 groups (p = 0.042 and p = 0.042, respectively). A receiver operating characteristics analysis revealed that a cut-off value of preprocedural average HR to predict the maintenance of SR was 85 beats/min (sensitivity: 37%, specificity: 85%, area under curve: 0.58). A multivariate analysis showed that preprocedural average HR ≥85 beats/min was independently associated with the maintenance of SR after RFCA (odds ratio 3.30, 95% confidence interval 1.47 to 8.04, p = 0.003). In conclusion, a relatively high preprocedural average HR might be a prognostic factor of maintenance of SR after RFCA for long-standing persistent AF.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Differences in Cardiac Mechanics and Exercise Physiology Among Heart Failure With Preserved Ejection Fraction Phenomapping Subgroups.</h4><i>Dixon DD, Beussink-Nelson L, Deo R, Shah SJ</i><br /><AbstractText>Unsupervised machine learning (phenomapping) has been used successfully to identify novel subgroups (phenogroups) of heart failure with preserved ejection fraction (HFpEF). However, further investigation of pathophysiological differences between HFpEF phenogroups is necessary to help determine potential treatment options. We performed speckle-tracking echocardiography and cardiopulmonary exercise testing (CPET) in 301 and 150 patients with HFpEF, respectively, as part of a prospective phenomapping study (median age 65 [25th to 75th percentile 56 to 73] years, 39% Black individuals, 65% female). Linear regression was used to compare strain and CPET parameters by phenogroup. All indicies of cardiac mechanics except for left ventricular global circumferential strain worsened in a stepwise fashion from phenogroups 1 to 3 after adjustment for demographic and clinical factors. After further adjustment for conventional echocardiographic parameters, phenogroup 3 had the worst left ventricular global longitudinal, right ventricular free wall, and left atrial booster and reservoir strain. On CPET, phenogroup 2 had the lowest exercise time and absolute peak oxygen consumption (VO<sub>2</sub>), driven primarily by obesity, whereas phenogroup 3 achieved the lowest workload, relative peak oxygen consumption (VO<sub>2</sub>), and heart rate reserve on multivariable-adjusted analyses. In conclusion, HFpEF phenogroups identified by unsupervised machine learning analysis differ in the indicies of cardiac mechanics and exercise physiology.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Sex Differences in Extensive Mitral Annular Calcification With Associated Mitral Valve Dysfunction.</h4><i>Churchill TW, Yucel E, Bernard S, Namasivayam M, ... Hung J, Bertrand PB</i><br /><AbstractText>Mitral annular calcification (MAC)-related mitral valve (MV) dysfunction is an increasingly recognized entity, which confers a high burden of morbidity and mortality. Although more common among women, there is a paucity of data regarding how the phenotype of MAC and the associated adverse clinical implications may differ between women and men. A total of 3,524 patients with extensive MAC and significant MAC-related MV dysfunction (i.e., transmitral gradient ≥3 mm Hg) were retrospectively analyzed from a large institutional database, with the goal of defining gender differences in clinical and echocardiographic characteristics and the prognostic importance of MAC-related MV dysfunction. We stratified patients into low- (3 to 5 mm Hg), moderate- (5 to 10 mm Hg), and high- (≥10 mm Hg) gradient groups and analyzed the gender differences in phenotype and outcome. The primary outcome was all-cause mortality, assessed using adjusted Cox regression models. Women represented the majority (67%) of subjects, were older (79.3 ± 10.4 vs 75.5 ± 10.9 years, p <0.001) and had a lower burden of cardiovascular co-morbidities than men. Women had higher transmitral gradients (5.7 ± 2.7 vs 5.3 ± 2.6 mm Hg, p <0.001), more concentric hypertrophy (49% vs 33%), and more mitral regurgitation. The median survival was 3.4 years (95% confidence interval 3.0 to 3.6) among women and 3.0 years (95% confidence interval 2.6 to 4.5) among men. The adjusted survival was worse among men, and the prognostic impact of the transmitral gradient did not differ overall by gender. In conclusion, we describe important gender differences among patients with MAC-related MV dysfunction and show worse adjusted survival among men; although, the adverse prognostic impact of the transmitral gradient was similar between men and women.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Long-Term Cause of Death in Patients Who Underwent Transcatheter Aortic Valve Implantation.</h4><i>Østergaard L, Køber N, Petersen JK, Jensen AD, ... Køber L, Fosbøl EL</i><br /><AbstractText>As our knowledge on treatment with transcatheter aortic valve implantation (TAVI) increases and more implantations are conducted, we need knowledge on how TAVI affects the end of life. Long-term causes of death remain sparsely described. The aim of the study was to examine differences in the cause of death according to time from TAVI. All patients who underwent TAVI in Denmark from 2008 to 2017 were matched on gender, age, and calendar year with controls from the background population (1:4). Mortality and the proportion of cardiovascular and noncardiovascular death was assessed at 1-year time points during follow-up. A total of 3,434 patients receiving TAVI and 13,672 controls were identified. The median follow-up was 2.67 years for patients receiving TAVI and 2.90 years for controls. Among patients receiving TAVI, 1,254 deaths (36.5%) were recorded, with 46.7% being from cardiovascular causes. The corresponding numbers for controls were 3,338 deaths (24.4%) and 27.2% being from cardiovascular causes. The proportion of cardiovascular deaths decreased from 53.8% in the first year after TAVI to 32.7% among those who died >7 years from TAVI (p = 0.008 for trend). For controls, no difference was seen in the proportion of cardiovascular death regardless of follow-up time. In conclusion, with data from nationwide registries, we provide results reassuring that patients with long-term survival from TAVI resemble the general public regarding the cause of death.</AbstractText><br /><br />Copyright © 2022.

<div><h4>Physician Perspectives on the Use of Beta Blockers in Heart Failure With Preserved Ejection Fraction.</h4><i>Musse M, Lau JD, Yum B, Pinheiro LC, ... Hummel SL, Goyal P</i><br /><AbstractText>β-blockers are commonly used in heart failure with preserved ejection fraction (HFpEF), even in the absence of a compelling indication and despite the potential to cause harm. Identifying reasons for β-blocker prescription in HFpEF could permit the development of strategies to reduce unnecessary use and potentially improve medication prescribing patterns in this vulnerable population. We administered an online survey regarding β-blocker prescribing behavior to physicians trained in internal medicine or geriatrics (noncardiology physicians) and to cardiologists at 2 large academic medical centers. The survey assessed the reasons for β-blocker initiation, agreement regarding initiation and/or continuation of β-blockers by another clinician, and deprescribing behavior. The response rate was 28.2% (n = 231). Among respondents, 68.2% reported initiating β-blockers in patients with HFpEF. The most common reason for initiating a β-blocker was for treatment of an atrial arrhythmia. Notably, 23.7% of physicians reported initiating a β-blocker without an evidence-based indication. When a β-blocker was considered not necessary, 40.1% of physicians reported they were rarely or never willing to deprescribe. The most common reason for not deprescribing a β-blocker when the physician felt that a β-blocker was unnecessary was the concern about interfering with another physicians\' treatment plan (76.6%). In conclusion, a significant proportion of noncardiology physicians and cardiologists report prescribing β-blockers to patients with HFpEF, even when evidence-based indications are absent, and rarely deprescribe β-blockers in these scenarios.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention of the Left Anterior Descending Artery.</h4><i>Megaly M, Zakhour S, Karacsonyi J, Basir MB, ... Brilakis ES, Alaswad K</i><br /><AbstractText>The left anterior descending artery (LAD) subtends a large myocardial territory. The outcomes of LAD chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have received limited study. We performed a retrospective analysis of all patients who underwent LAD CTO PCI at a high-volume single center. Outcomes included in-hospital and long-term major adverse cardiovascular events (MACEs) and changes in left ventricular ejection fraction (LVEF). We performed a subgroup analysis of patients with ischemic cardiomyopathy, defined as an LVEF of 40% or less. From December 2014 to February 2021, 237 patients underwent LAD CTO PCI. The technical success rate was 97.4%, and the in-hospital MACE rate was 5.4%, A landmark analysis after hospital discharge showed an overall survival of 92% and 85% MACE-free survival at 2 years. There was no difference in overall survival or MACE-free survival between those who had ischemic cardiomyopathy versus those who did not. In patients with ischemic cardiomyopathy, LAD CTO PCI was associated with significant improvement in LVEF (10.9% at 9 months), which was further pronounced when these patients had a proximal LAD CTO and were on optimal medical therapy (14% at 6 months). In a single high-volume center, LAD CTO PCI was associated with 92% overall survival at 2 years, with no difference in survival between patients with or without ischemic cardiomyopathy. LAD CTO PCI was associated with an absolute 10% increase in LVEF at 9 months in patients with ischemic cardiomyopathy.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Meta-Analysis on the Impact of Coronary Bypass Graft Markers on Angiographic Procedural Outcomes.</h4><i>Sattar Y, DeCicco D, Faisaluddin M, Almas T, ... Daggubati R, Bianco C</i><br /><AbstractText>Utilization of radio-opaque coronary artery bypass graft markers is known to decrease the amount of contrast dye required to complete the procedure. The practice of marking bypass grafts varies significantly among surgeons. Limited data exist comparing the outcomes of percutaneous coronary intervention with and without coronary artery bypass graft (CABG) markers. We sought to explore the impact of proximal radio-opaque markers placed during CABG in subsequent percutaneous coronary intervention procedural risks. In our understanding of the current literature, this is the first meta-analysis conducted to evaluate the association between procedural angiographic metrics and CABG radio-opaque markers. We performed a query of MEDLINE and Scopus databases through August 2022 to identify relevant studies evaluating procedural metrics among patients with previous CABG with and without radio-opaque markers who underwent angiography. The primary outcomes of interest were fluoroscopy time, amount of contrast, and duration of angiography. We identified a total of 4 studies with 2,046 patients with CABG (CABG with markers n = 688, CABG without markers n = 1,518).<sup>2-5</sup> Total fluoroscopy time was significantly reduced among patients with CABG markers compared with those with no markers (odds ratio [OR] -3.63, p <0.0001). The duration of angiography (OR -36.39, p >0.10) was reduced, although the result was not statistically significant. However, the amount of contrast utilization was significantly reduced (OR -33.41, p <0.0001). In patients who underwent CABG with radio-opaque markers, angiographic procedural metrics were improved, including reduced fluoroscopic time and the amount of contrast agent required compared with no markers.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Echocardiographic Mitral Annular Calcification is Associated With Atrial Fibrillation Recurrence After Catheter Ablation.</h4><i>Yao Y, Zhang Z, Xue J, Chen Z, ... Wang J, Long D</i><br /><AbstractText>There is a significant relation between mitral annular calcification (MAC) and the development of atrial fibrillation (AF) and major adverse cardiovascular events. However, the influence of MAC on the outcome of AF ablation remains unknown. The study cohort included 785 consecutive patients who underwent successful ablation. AF recurrence was monitored 3 months after ablation. Cox proportional hazards models were used to assess the association between MAC and AF recurrence. Kaplan-Meier analysis was performed to calculate the incidence of AF recurrence. Over a follow-up period of 16 ± 10 months, 190 patients (24.2%) experienced AF recurrence after ablation. MAC by echocardiography was identified in 42 patients (22%) with AF recurrence but only 60 without (10%, p <0.001). Patients with MAC were older (p <0.001), more often women (p <0.001), with a higher prevalence of hypertension (p <0.001) and diabetes mellitus (p<0.001), moderate/severe mitral regurgitation (p <0.001), larger left atrial dimension (p <0.001), and higher CHA<sub>2</sub>DS<sub>2</sub>-VASc score (p <0.001). Patients with MAC were more likely to develop AF recurrence than those without (36% vs 22%, respectively, p = 0.002). MAC was significantly associated with AF recurrence in the unadjusted analysis (hazard ratio 1.77, 95% confidence interval 1.26 to 2.58, p <0.001) and remained statistically significant after the multivariate adjustment (hazard ratio 1.48, 95% confidence interval 1.13 to 1.95, p = 0.001). In conclusion, echocardiographic MAC is significantly associated with an increased risk of AF recurrence after successful ablation, demonstrating an independent predictive value other than the established risk factors.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention After a Previous Failed Attempt.</h4><i>Rempakos A, Kostantinis S, Simsek B, Karacsonyi J, ... Burke NM, Brilakis ES</i><br /><AbstractText>The impact of a previous failure on procedural techniques and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We examined the clinical and angiographic characteristics and procedural outcomes of 9,393 patients who underwent 9,560 CTO PCIs at 42 United States and non-United States centers between 2012 and 2022. A total of 1,904 CTO lesions (20%) had a previous failed PCI attempt. Patients who underwent reattempt CTO PCI were more likely to have a family history of coronary artery disease (37% vs 31%, p <0.001) and dyslipidemia (87.9% vs 84.3%, p <0.001) but were less likely to have heart failure (25.1% vs 29.5%; p <0.001) and cerebrovascular disease (8.7% vs 10.4%, p = 0.04). Patients with previous failure had a higher Japanese CTO (3.33 ± 1.16 vs 2.12 ± 1.19, p <0.001) score and required longer procedure (120 vs 111 minutes, p <0.001) and fluoroscopy (46.9 vs 40.4 minutes, p <0.001) times and higher air kerma radiation dose (2.3 vs 2.1 gray, p = 0.013). Technical success rates (84.3% vs 86.5%, p = 0.011) were lower in patients with a previous failure compared with patients who underwent first-attempt CTO PCI with no significant difference in in-hospital major adverse cardiac events. After adjusting for potential confounders, a previous failure was not associated with technical failure. Operators performing >30 CTO PCIs annually were more likely to achieve technical success in patients with previous failure. In conclusion, a previous failed CTO PCI attempt was associated with higher lesion complexity, longer procedure time, and lower technical success; however, the association with lower technical success did not remain significant in multivariable analysis.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.
