<div><h4>Sodium-glucose cotransporter 2 inhibitors vs. sitagliptin in heart failure and type 2 diabetes: an observational cohort study.</h4><i>Fu EL, Patorno E, Everett BM, Vaduganathan M, ... Schneeweiss S, Desai RJ</i><br /><b>Aims</b><br />The effectiveness of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with heart failure (HF) in routine clinical practice is not extensively studied. This study aimed to evaluate the comparative effectiveness of SGLT2i vs. sitagliptin in older adults with HF and type 2 diabetes and to investigate whether there were any differences between agents within the SGLT2i class or for reduced and preserved ejection fraction.<br /><b>Methods and results</b><br />Using Medicare claims data (April 2013 to December 2019), 16 253 SGLT2i initiators vs. 43 352 initiators of sitagliptin aged ≥65 years with type 2 diabetes and HF were included. The primary outcome was a composite of all-cause mortality, hospitalization for HF or urgent visit requiring intravenous diuretics; secondary outcomes included its individual components. Propensity score fine stratification weighted Cox regression was used to adjust for 100 pre-exposure characteristics. Mean age was 74 years; 49.8% were women. Initiation of SGLT2i vs. sitagliptin was associated with a lower risk of the primary composite outcome [adjusted hazard ratio (HR) 0.72; 95% confidence interval 0.67-0.77]. The adjusted HRs were 0.70 (0.63-0.78) for all-cause mortality, 0.64 (0.58-0.70) for hospitalization for HF, and 0.77 (0.69-0.86) for urgent visit requiring intravenous diuretics. Similar associations with the primary composite outcome were observed for all three agents within the SGLT2i class, for reduced and preserved ejection fraction, and subgroups based on demographics, comorbidities, and other HF treatments. Bias-calibrated HRs for the primary endpoint using negative and positive control outcomes ranged between 0.81 and 0.89, suggesting that the observed benefit could not be fully explained by residual confounding.<br /><b>Conclusion</b><br />In routine US clinical practice, SGLT2i demonstrated robust clinical effectiveness in older adults with HF and type 2 diabetes compared with sitagliptin, with no evidence of heterogeneity across the SGLT2i class or across ejection fraction.<br /><br />© The Author(s) 2023.

<div><h4>SCORE2-Diabetes: 10-year cardiovascular risk estimation in type 2 diabetes in Europe.</h4><i>SCORE2-Diabetes Working Group and the ESC Cardiovascular Risk Collaboration </i><br /><b>Aims</b><br />To develop and validate a recalibrated prediction model (SCORE2-Diabetes) to estimate the 10-year risk of cardiovascular disease (CVD) in individuals with type 2 diabetes in Europe.<br /><b>Methods and results</b><br />SCORE2-Diabetes was developed by extending SCORE2 algorithms using individual-participant data from four large-scale datasets comprising 229 460 participants (43 706 CVD events) with type 2 diabetes and without previous CVD. Sex-specific competing risk-adjusted models were used including conventional risk factors (i.e. age, smoking, systolic blood pressure, total, and HDL-cholesterol), as well as diabetes-related variables (i.e. age at diabetes diagnosis, glycated haemoglobin [HbA1c] and creatinine-based estimated glomerular filtration rate [eGFR]). Models were recalibrated to CVD incidence in four European risk regions. External validation included 217 036 further individuals (38 602 CVD events), and showed good discrimination, and improvement over SCORE2 (C-index change from 0.009 to 0.031). Regional calibration was satisfactory. SCORE2-Diabetes risk predictions varied several-fold, depending on individuals\' levels of diabetes-related factors. For example, in the moderate-risk region, the estimated 10-year CVD risk was 11% for a 60-year-old man, non-smoker, with type 2 diabetes, average conventional risk factors, HbA1c of 50 mmol/mol, eGFR of 90 mL/min/1.73 m2, and age at diabetes diagnosis of 60 years. By contrast, the estimated risk was 17% in a similar man, with HbA1c of 70 mmol/mol, eGFR of 60 mL/min/1.73 m2, and age at diabetes diagnosis of 50 years. For a woman with the same characteristics, the risk was 8% and 13%, respectively.<br /><b>Conclusion</b><br />SCORE2-Diabetes, a new algorithm developed, calibrated, and validated to predict 10-year risk of CVD in individuals with type 2 diabetes, enhances identification of individuals at higher risk of developing CVD across Europe.<br /><br />© The Author(s) 2023.

<div><h4>Modifiable cardiovascular risk factors and genetics for targeted prevention of dementia.</h4><i>Juul Rasmussen I, Frikke-Schmidt R</i><br /><AbstractText>Dementia is a major global challenge for health and social care in the 21st century. A third of individuals >65 years of age die with dementia, and worldwide incidence numbers are projected to be higher than 150 million by 2050. Dementia is, however, not an inevitable consequence of old age; 40% of dementia may theoretically be preventable. Alzheimer\'s disease (AD) accounts for approximately two-thirds of dementia cases and the major pathological hallmark of AD is accumulation of amyloid-β. Nevertheless, the exact pathological mechanisms of AD remain unknown. Cardiovascular disease and dementia share several risk factors and dementia often coexists with cerebrovascular disease. In a public health perspective, prevention is crucial, and it is suggested that a 10% reduction in prevalence of cardiovascular risk factors could prevent more than nine million dementia cases worldwide by 2050. Yet this assumes causality between cardiovascular risk factors and dementia and adherence to the interventions over decades for a large number of individuals. Using genome-wide association studies, the entire genome can be scanned for disease/trait associated loci in a hypothesis-free manner, and the compiled genetic information is not only useful for pinpointing novel pathogenic pathways but also for risk assessments. This enables identification of individuals at high risk, who likely will benefit the most from a targeted intervention. Further optimization of the risk stratification can be done by adding cardiovascular risk factors. Additional studies are, however, highly needed to elucidate dementia pathogenesis and potential shared causal risk factors between cardiovascular disease and dementia.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Vegetarian or vegan diets and blood lipids: a meta-analysis of randomized trials.</h4><i>Koch CA, Kjeldsen EW, Frikke-Schmidt R</i><br /><b>Aims</b><br />Due to growing environmental focus, plant-based diets are increasing steadily in popularity. Uncovering the effect on well-established risk factors for cardiovascular diseases, the leading cause of death worldwide, is thus highly relevant. Therefore, a systematic review and meta-analysis were conducted to estimate the effect of vegetarian and vegan diets on blood levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides, and apolipoprotein B.<br /><b>Methods and results</b><br />Studies published between 1980 and October 2022 were searched for using PubMed, Embase, and references of previous reviews. Included studies were randomized controlled trials that quantified the effect of vegetarian or vegan diets vs. an omnivorous diet on blood lipids and lipoprotein levels in adults over 18 years. Estimates were calculated using a random-effects model. Thirty trials were included in the study. Compared with the omnivorous group, the plant-based diets reduced total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B levels with mean differences of -0.34 mmol/L (95% confidence interval, -0.44, -0.23; P = 1 × 10-9), -0.30 mmol/L (-0.40, -0.19; P = 4 × 10-8), and -12.92 mg/dL (-22.63, -3.20; P = 0.01), respectively. The effect sizes were similar across age, continent, duration of study, health status, intervention diet, intervention program, and study design. No significant difference was observed for triglyceride levels.<br /><b>Conclusion</b><br />Vegetarian and vegan diets were associated with reduced concentrations of total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B-effects that were consistent across various study and participant characteristics. Plant-based diets have the potential to lessen the atherosclerotic burden from atherogenic lipoproteins and thereby reduce the risk of cardiovascular disease.<br /><br />© The Author(s) 2023.

<div><h4>Heart failure, peripheral artery disease, and dapagliflozin: a patient-level meta-analysis of DAPA-HF and DELIVER.</h4><i>Butt JH, Kondo T, Yang M, Jhund PS, ... Solomon SD, McMurray JJV</i><br /><b>Aims</b><br />Because an increased risk of amputation with canagliflozin was reported in the CANVAS trials, there has been a concern about the safety of sodium-glucose cotransporter 2 inhibitors in patients with peripheral artery disease (PAD) who are at higher risk of amputation.<br /><b>Methods and results</b><br />A patient-level pooled analysis of the DAPA-HF and DELIVER trials, which evaluated the efficacy and safety of dapagliflozin in patients with heart failure (HF) with reduced, mildly reduced/preserved ejection fraction, respectively, was conducted. In both trials, the primary outcome was the composite of worsening HF or cardiovascular death, and amputation was a prespecified safety outcome. Peripheral artery disease history was available for 11 005 of the total 11 007 patients. Peripheral artery disease was reported in 809 of the 11 005 patients (7.4%). Median follow-up was 22 months (interquartile range 17-30). The rate of the primary outcome (per 100 person-years) was higher in PAD patients than that in non-PAD patients: 15.1 [95% confidence interval (CI) 13.1-17.3) vs. 10.6 (10.2-11.1]; adjusted hazard ratio 1.23 (95% CI 1.06-1.43). The benefit of dapagliflozin on the primary outcome was consistent in patients with [hazard ratio 0.71 (95% CI 0.54-0.94)] and without PAD [0.80 (95% CI 0.73-0.88)] (Pinteraction = 0.39). Amputations, while more frequent in PAD patients, were not more common with dapagliflozin, compared with placebo, irrespective of PAD status (PAD, placebo 4.2% vs. dapagliflozin 3.7%; no PAD, placebo 0.4% vs. dapagliflozin 0.4%) (Pinteraction = 1.00). Infection rather than ischaemia was the main trigger for amputation, even in patients with PAD.<br /><b>Conclusion</b><br />The risk of worsening HF or cardiovascular death was higher in patients with PAD, as was the risk of amputation. The benefits of dapagliflozin were consistent in patients with and without PAD, and dapagliflozin did not increase the risk of amputation.<br /><br />© The Author(s) 2023.

<div><h4>Dapagliflozin and diuretic utilization in heart failure with mildly reduced or preserved ejection fraction: the DELIVER trial.</h4><i>Chatur S, Vaduganathan M, Claggett B, Vardeny O, ... McMurray JJV, Solomon SD</i><br /><b>Aims</b><br />Dapagliflozin reduced the combined risk of worsening heart failure or cardiovascular death among patients with heart failure with mildly reduced or preserved ejection fraction. In this study, the safety and efficacy of dapagliflozin according to background diuretic therapy and the influence of dapagliflozin on longitudinal diuretic use were evaluated.<br /><b>Methods and results</b><br />In this pre-specified analysis of the Dapagliflozin Evaluation to Improve the LIVEs of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial, the effects of dapagliflozin vs. placebo were assessed in the following subgroups: no diuretic, non-loop diuretic, and loop diuretic furosemide equivalent doses of <40, 40, and >40 mg, respectively. Of the 6263 randomized patients, 683 (10.9%) were on no diuretic, 769 (12.3%) were on a non-loop diuretic, and 4811 (76.8%) were on a loop diuretic at baseline. Treatment benefits of dapagliflozin on the primary composite outcome were consistent by diuretic use categories (Pinteraction = 0.64) or loop diuretic dose (Pinteraction = 0.57). Serious adverse events were similar between dapagliflozin and placebo arms, irrespective of diuretic use or dosing. Dapagliflozin reduced new initiation of loop diuretics by 32% [hazard ratio (HR) 0.68; 95% confidence interval (CI): 0.55-0.84, P < 0.001] but did not influence discontinuations/disruptions (HR 0.98; 95% CI: 0.86-1.13, P = 0.83) in follow-up. First sustained loop diuretic dose increases were less frequent, and sustained dose decreases were more frequent in patients treated with dapagliflozin: net difference of -6.5% (95% CI: -9.4 to -3.6; P < 0.001). The mean dose of loop diuretic increased over time in the placebo arm, a longitudinal increase that was significantly attenuated with treatment with dapagliflozin (placebo-corrected treatment effect of -2.5 mg/year; 95% CI: -1.5, -3.7, P < 0.001).<br /><b>Conclusion</b><br />In patients with heart failure with mildly reduced or preserved ejection fraction, the clinical benefits of dapagliflozin relative to placebo were consistent across a wide range of diuretic categories and doses with a similar safety profile. Treatment with dapagliflozin significantly reduced new loop diuretic requirement over time.<br /><br />© The Author(s) 2023.

<div><h4>Telemonitoring for heart failure: a meta-analysis.</h4><i>Scholte NTB, Gürgöze MT, Aydin D, Theuns DAMJ, ... van der Boon RMA, Brugts JJ</i><br /><b>Aims</b><br />Telemonitoring modalities in heart failure (HF) have been proposed as being essential for future organization and transition of HF care, however, efficacy has not been proven. A comprehensive meta-analysis of studies on home telemonitoring systems (hTMS) in HF and the effect on clinical outcomes are provided.<br /><b>Methods and results</b><br />A systematic literature search was performed in four bibliographic databases, including randomized trials and observational studies that were published during January 1996-July 2022. A random-effects meta-analysis was carried out comparing hTMS with standard of care. All-cause mortality, first HF hospitalization, and total HF hospitalizations were evaluated as study endpoints. Sixty-five non-invasive hTMS studies and 27 invasive hTMS studies enrolled 36 549 HF patients, with a mean follow-up of 11.5 months. In patients using hTMS compared with standard of care, a significant 16% reduction in all-cause mortality was observed [pooled odds ratio (OR): 0.84, 95% confidence interval (CI): 0.77-0.93, I2: 24%], as well as a significant 19% reduction in first HF hospitalization (OR: 0.81, 95% CI 0.74-0.88, I2: 22%) and a 15% reduction in total HF hospitalizations (pooled incidence rate ratio: 0.85, 95% CI 0.76-0.96, I2: 70%).<br /><b>Conclusion</b><br />These results are an advocacy for the use of hTMS in HF patients to reduce all-cause mortality and HF-related hospitalizations. Still, the methods of hTMS remain diverse, so future research should strive to standardize modes of effective hTMS.<br /><br />© The Author(s) 2023.

<div><h4>NT-proBNP and high-intensity care for acute heart failure: the STRONG-HF trial.</h4><i>Adamo M, Pagnesi M, Mebazaa A, Davison B, ... Cotter G, Metra M</i><br /><b>Background:</b><br/>and aims</b><br />STRONG-HF showed that rapid up-titration of guideline-recommended medical therapy (GRMT), in a high intensity care (HIC) strategy, was associated with better outcomes compared to usual care (UC). The aim of this study was to assess the role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) at baseline and its changes early during up-titration.<br /><b>Methods</b><br />A total of 1077 patients hospitalized for acute heart failure (HF) and with a >10% NT-proBNP decrease from screening (i.e. admission) to randomization (i.e. pre-discharge), were included. Patients in HIC were stratified by further NT-proBNP changes from randomization to 1 week later as decreased (≥30% decrease), stable (<30% decrease to ≤10% increase) or increased (>10% increase). The primary endpoint was 180-day HF readmission or death.<br /><b>Results</b><br />The effect of HIC vs. UC was independent of baseline NT-proBNP. Patients in the HIC group with stable or increased NT-proBNP were older, with more severe acute HF and worse renal and liver function. Per protocol, patients with increased NT-proBNP received more diuretics and were up-titrated more slowly during the first weeks after discharge. However, by 6 months they reached 70.4% optimal GRMT doses, compared with 80.3% for those with NT-proBNP decrease. As a result, the primary endpoint at 60 and 90 days occurred in 8.3% and 11.1% of patients with increased NT-proBNP vs 2.2% and 4.0% in those with decreased NT-proBNP (p=0.039 and p=0.045, respectively). However, no difference in outcome was found at 180 days (13.5% vs. 13.2%; p=0.93).<br /><b>Conclusions</b><br />Among patients with acute HF enrolled in STRONG-HF, HIC reduced 180-day HF readmission or death regardless of baseline NT-proBNP. GRMT up-titration early post-discharge utilizing increased NT-proBNP as guidance to increase diuretic therapy and reduce the GRMT up-titration rate resulted in the same 180-day outcomes regardless of early post-discharge NT-proBNP change.<br /><br />© The Author(s) 2023.

<div><h4>Conventional heart failure therapy in cardiac ATTR amyloidosis.</h4><i>Ioannou A, Massa P, Patel RK, Razvi Y, ... Gillmore JD, Fontana M</i><br /><b>Background:</b><br/>and aims</b><br />The aims of this study were to assess prescription patterns, dosages, discontinuation rates and association with prognosis of conventional heart failure (HF) medications in patients with transthyretin cardiac amyloidosis (ATTR-CA).<br /><b>Methods</b><br />A retrospective analysis of all consecutive patients diagnosed with ATTR-CA at the National Amyloidosis Centre between 2000-2022 identified 2371 patients with ATTR-CA.<br /><b>Results</b><br />Prescription of HF medications was greater among patients with a more severe cardiac phenotype, comprising beta-blockers in 55.4%, angiotensin-converting enzyme inhibitors (ACEi)/angiotensin-II receptor blockers (ARB) in 57.4%, and mineralocorticoid receptor antagonists (MRAs) in 39.0% of cases. During a median follow-up of 27.8 months (IQR 10.6-51.3), 21.7% had beta-blockers discontinued, and 32.9% had ACEi/ARB discontinued. In contrast, only 7.5% had MRAs discontinued. Propensity score-matched analysis demonstrated that treatment with MRAs was independently associated with a reduced risk of mortality in the overall population (HR 0.77 [95% CI 0.66-0.89], P<0.001) and in a pre-specified subgroup of patients with a left ventricular ejection fraction (LVEF) >40% (HR 0.75 [95% CI 0.63-0.90], P=0.002); and treatment with low-dose beta-blockers was independently associated with a reduced risk of mortality in a pre-specified subgroup of patients with a LVEF ≤40% (HR 0.61 [95% CI 0.45-0.83], P=0.002). No convincing differences were found for treatment with ACEi/ARBs.<br /><b>Conclusions</b><br />Conventional HF medications are currently not widely prescribed in ATTR-CA, and those that received medication had more severe cardiac disease. Beta-blockers and ACEi/ARBs were often discontinued, but low-dose beta-blockers were associated with reduced risk of mortality in patients with a LVEF ≤40%. In contrast, MRAs were rarely discontinued and were associated with reduced risk of mortality in the overall population; but these findings require confirmation in prospective randomized controlled trials.<br /><br />© The Author(s) 2023.

Patients were randomized to dapagliflozin 10 mg once daily or metolazone 5-10 mg once daily for a 3-day treatment period, with follow-up for primary and secondary endpoints until day 5 (96 hours). The primary endpoint was diuretic effect, assessed by change in weight (kg). Secondary endpoints included change in pulmonary congestion (lung ultrasound), loop diuretic efficiency (weight change per 40 mg of furosemide), and a volume assessment score.<br /><b>Results</b><br />61 patients were randomized. The mean (±standard deviation) cumulative dose of furosemide at 96 hours was 976 (±492) mg in the dapagliflozin group and 704 (±428) mg in patients assigned to metolazone. The mean (±standard deviation) decrease in weight at 96 hours was 3.0 (2.5) kg with dapagliflozin compared to 3.6 (2.0) kg with metolazone [mean difference 0.65, 95% confidence interval (CI) -0.12,1.41 kg; p=0.11]. Loop diuretic efficiency was less with dapagliflozin than with metolazone [mean 0.15 (0.12) versus 0.25 (0.19); difference -0.08, 95% CI -0.17,0.01 kg; p=0.10]. Changes in pulmonary congestion and volume assessment score were similar between treatments. Decreases in plasma sodium and potassium and increases in urea and creatinine were smaller with dapagliflozin than with metolazone. Serious adverse events were similar between treatments.<br /><b>Conclusion</b><br />In patients with heart failure and loop diuretic resistance, dapagliflozin was not more effective at relieving congestion than metolazone.

Braunwald E, Solomon SD</i><br /><b>Background:</b><br/>and aims</b><br />The PARAGLIDE-HF trial demonstrated reductions in natriuretic peptides with sacubitril/valsartan compared with valsartan in patients with heart failure (HF) with mildly reduced or preserved ejection fraction who had a recent worsening HF event, but was not adequately powered to examine clinical outcomes. PARAGON-HF included a subset of PARAGLIDE-HF-like patients who were recently hospitalized for HF. Participant-level data from PARAGLIDE-HF and PARAGON-HF were pooled to better estimate the efficacy and safety of sacubitril/valsartan in reducing cardiovascular and renal events in HF with mildly reduced or preserved ejection fraction.<br /><b>Methods</b><br />Both PARAGLIDE-HF and PARAGON-HF were multicenter, double-blind, randomized, active-controlled trials of sacubitril/valsartan vs. valsartan in patients with HF with mildly reduced or preserved left ventricular ejection fraction (LVEF >40% in PARAGLIDE-HF and ≥45% in PARAGON-HF). In the pre-specified primary analysis, we pooled participants in PARAGLIDE-HF (all of whom were enrolled during or within 30 days of a worsening HF event) with a \'PARAGLIDE-like\' subset of PARAGON-HF (those hospitalized for HF within 30 days). We also pooled the entire PARAGLIDE-HF and PARAGON-HF populations for a broader context. The primary endpoint for this analysis was the composite of total worsening HF events (including first and recurrent HF hospitalizations and urgent visits) and cardiovascular death. The secondary endpoint was the pre-specified renal composite endpoint for both studies (≥50% decline in estimated glomerular filtration rate from baseline, end-stage renal disease, or renal death).<br /><b>Results</b><br />Compared with valsartan, sacubitril/valsartan significantly reduced total worsening HF events and cardiovascular death in both the primary pooled analysis of participants with recent worsening HF (n=1,088; rate ratio [RR] 0.78; 95% confidence interval [CI] 0.61-0.99; P=0.042) and in the pooled analysis of all participants (n=5,262; RR 0.86; 95% CI: 0.75-0.98; P=0.027). In the pooled analysis of all participants, first nominal statistical significance was reached by day 9 after randomization and treatment benefits were larger in those with LVEF ≤60% (RR 0.78; 95% CI 0.66-0.91) compared with those with LVEF >60% (RR 1.09; 95% CI 0.86-1.40; Pinteraction=0.021). Sacubitril/valsartan was also associated with lower rates of the renal composite endpoint in the primary pooled analysis (hazard ratio [HR] 0.67; 95% CI 0.43-1.05; P=0.080) and the pooled analysis of all participants (HR 0.60; 95% CI 0.44-0.83; P=0.002).<br /><b>Conclusions</b><br />In pooled analyses of PARAGLIDE-HF and PARAGON-HF, sacubitril/valsartan reduced cardiovascular and renal events among patients with HF with mildly reduced or preserved ejection fraction. These data provide support for use of sacubitril/valsartan in patients with HF with mildly reduced or preserved ejection fraction, particularly among those with an LVEF below normal, regardless of care setting.<br /><br />© The Author(s) 2023.

We have conducted a meta-analysis of large randomized trials investigating this question.<br /><b>Methods</b><br />A systematic literature search was performed for randomized clinical trials (RCTs) with PA pressure monitoring devices in patients with HF. The primary outcome of interest was the total number of HF hospitalizations. Other outcomes assessed were urgent visits leading to treatment with intravenous diuretics, all-cause mortality, and composites. Treatment effects are expressed as hazard ratios, and pooled effect estimates were obtained applying random effects meta-analyses.<br /><b>Results</b><br />Three eligible RCTs were identified that included 1898 outpatients in New York Heart Association functional class II-IV, either hospitalized for HF in the prior 12 months or with elevated plasma NT-proBNP concentrations. Mean follow-up was 14.7 months, 67.8% of the patients were men, and 65.8% had an ejection fraction ≤40%. Compared to patients in the control group, the hazard ratio (95% confidence interval) for total HF hospitalizations in those randomized to PA pressure monitoring was 0.70 (0.58-0.86) (p=0.0005).

<div><h4>Novel mechanisms and therapeutic targets in atherosclerosis: inflammation and beyond.</h4><i>Weber C, Habenicht AJR, von Hundelshausen P</i><br /><AbstractText>This review based on the ESC William Harvey Lecture in Basic Science 2022 highlights recent experimental and translational progress on the therapeutic targeting of the inflammatory components in atherosclerosis, introducing novel strategies to limit side effects and to increase efficacy. Since the validation of the inflammatory paradigm in CANTOS and COLCOT, efforts to control the residual risk conferred by inflammation have centred on the NLRP3 inflammasome-driven IL-1β-IL6 axis. Interference with the co-stimulatory dyad CD40L-CD40 and selective targeting of tumour necrosis factor-receptor associated factors (TRAFs), namely the TRAF6-CD40 interaction in macrophages by small molecule inhibitors, harbour intriguing options to reduce established atherosclerosis and plaque instability without immune side effects. The chemokine system crucial for shaping immune cell recruitment and homoeostasis can be fine-tuned and modulated by its heterodimer interactome. Structure-function analysis enabled the design of cyclic, helical, or linked peptides specifically targeting or mimicking these interactions to limit atherosclerosis or thrombosis by blunting myeloid recruitment, boosting regulatory T cells, inhibiting platelet activity, or specifically blocking the atypical chemokine MIF without notable side effects. Finally, adventitial neuroimmune cardiovascular interfaces in advanced atherosclerosis show robust restructuring of innervation from perivascular ganglia and employ sensory neurons of dorsal root ganglia to enter the central nervous system and to establish an atherosclerosis-brain circuit sensor, while sympathetic and vagal efferents project to the celiac ganglion to create an atherosclerosis-brain circuit effector. Disrupting this circuitry by surgical or chemical sympathectomy limited disease progression and enhanced plaque stability, opening exciting perspectives for selective and tailored intervention beyond anti-inflammatory strategies.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Management strategies for heavily calcified coronary stenoses: an EAPCI clinical consensus statement in collaboration with the EURO4C-PCR group.</h4><i>Barbato E, Gallinoro E, Abdel-Wahab M, Andreini D, ... Wijns W, Ribichini F</i><br /><AbstractText>Since the publication of the 2015 EAPCI consensus on rotational atherectomy, the number of percutaneous coronary interventions (PCI) performed in patients with severely calcified coronary artery disease has grown substantially. This has been prompted on one side by the clinical demand for the continuous increase in life expectancy, the sustained expansion of the primary PCI networks worldwide and the routine performance of revascularization procedures in elderly patients; on the other side, the availability of new and dedicated technologies such as orbital atherectomy and intravascular lithotripsy, as well as the optimization of the rotational atherectomy system, have increased operators\' confidence in attempting more challenging PCI. This current EAPCI clinical consensus statement prepared in collaboration with the EURO4C-PCR group describes the comprehensive management of patients with heavily calcified coronary stenoses, starting with how to use non-invasive and invasive imaging to assess calcium burden and inform procedural planning. Objective and practical guidance is provided on the selection of the optimal interventional tool and technique based on the specific calcium morphology and anatomic location. Finally, the specific clinical implications of treating these patients are considered, including the prevention and management of complications, and the importance of adequate training and education.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Left main bifurcation stenting: impact of residual ischaemia on cardiovascular mortality.</h4><i>Wang HY, Zhang R, Dou K, Huang Y, ... Wijns W, Xu B</i><br /><b>Background:</b><br/>and aims</b><br />The present study sought to determine the rate and prognostic implications of post-procedural physiologically significant residual ischemia according to Murray law-based quantitative flow ratio (μQFR) after left main (LM) bifurcation percutaneous coronary intervention (PCI).<br /><b>Methods</b><br />Consecutive patients undergoing LM bifurcation stenting at a large tertiary care center between January 2014 and December 2016 with available post-PCI μQFR were included. Physiologically significant residual ischemia was defined by post-PCI μQFR values ≤0.80 in the left anterior descending (LAD) or circumflex artery (LCX). The primary outcome was 3-year cardiovascular death. The major secondary outcome was 3-year bifurcation oriented composite endpoint (BOCE).<br /><b>Results</b><br />Among 1,170 included patients with analyzable post-PCI μQFR, 155 (13.2%) had residual ischemia in either LAD or LCX. Patients with vs. those without residual ischemia had a higher risk of 3-year cardiovascular mortality (5.4% vs. 1.3%; adjusted hazard ratio [HR] 3.20, 95% confidence interval [CI]: 1.16-8.80). The 3-year risk of BOCE was significantly higher in the residual ischemia group (17.8% vs. 5.8%; adjusted HR 2.79, 95% CI: 1.68-4.64), driven by higher incidence of the composite of cardiovascular death and target bifurcation-related myocardial infarction (14.0% vs. 3.3%; adjusted HR 4.06, 95% CI: 2.22-7.42). A significant, inverse association was observed between continuous post-PCI μQFR and the risk of clinical outcomes (per 0.1 μQFR decrease, HR of cardiovascular death 1.27, 95% CI: 1.00-1.62; HR of BOCE 1.29, 95% CI: 1.14-1.47).<br /><b>Conclusion</b><br />After angiographically successful LM bifurcation PCI, residual ischemia assessed by μQFR was identified in 13.2% of patients and was associated with higher risk of 3-year cardiovascular death, indicating the superior prognostic value of post-PCI physiological assessment.<br /><br />© The Author(s) 2023.

<div><h4>Takotsubo syndrome is a coronary microvascular disease: experimental evidence.</h4><i>Dong F, Yin L, Sisakian H, Hakobyan T, ... Chilian WM, Ohanyan V</i><br /><b>Background:</b><br/>and aims</b><br />Takotsubo syndrome (TTS) is a conundrum without consensus about the cause. In a murine model of coronary microvascular dysfunction (CMD), abnormalities in myocardial perfusion played a key role in the development of TTS.<br /><b>Methods and results</b><br />Vascular Kv1.5 channels connect coronary blood flow to myocardial metabolism and their deletion mimics the phenotype of CMD. To determine if TTS is related to CMD, wild-type (WT), Kv1.5-/-, and TgKv1.5-/- (Kv1.5-/- with smooth muscle-specific expression Kv1.5 channels) mice were studied following transaortic constriction (TAC). Measurements of left ventricular (LV) fractional shortening (FS) in base and apex, and myocardial blood flow (MBF) were completed with standard and contrast echocardiography. Ribonucleic Acid deep sequencing was performed on LV apex and base from WT and Kv1.5-/- (control and TAC). Changes in gene expression were confirmed by real-time-polymerase chain reaction. MBF was increased with chromonar or by smooth muscle expression of Kv1.5 channels in the TgKv1.5-/-. TAC-induced systolic apical ballooning in Kv1.5-/-, shown as negative FS (P < 0.05 vs. base), which was not observed in WT, Kv1.5-/- with chromonar, or TgKv1.5-/-. Following TAC in Kv1.5-/-, MBF was lower in LV apex than in base. Increasing MBF with either chromonar or in TgKv1.5-/- normalized perfusion and function between LV apex and base (P = NS). Some genetic changes during TTS were reversed by chromonar, suggesting these were independent of TAC and more related to TTS.<br /><b>Conclusion</b><br />Abnormalities in flow regulation between the LV apex and base cause TTS. When perfusion is normalized between the two regions, normal ventricular function is restored.<br /><br />© The Author(s) 2023.

<div><h4>Rapid, accurate publication and dissemination of clinical trial results: benefits and challenges.</h4><i>Zannad F, Crea F, Keaney J, Spencer S, ... Winslow R, Jessup M</i><br /><AbstractText>Large-scale clinical trials are essential in cardiology and require rapid, accurate publication, and dissemination. Whereas conference presentations, press releases, and social media disseminate information quickly and often receive considerable coverage by mainstream and healthcare media, they lack detail, may emphasize selected data, and can be open to misinterpretation. Preprint servers speed access to research manuscripts while awaiting acceptance for publication by a journal, but these articles are not formally peer-reviewed and sometimes overstate the findings. Publication of trial results in a major journal is very demanding but the use of existing checklists can help accelerate the process. In case of rejection, procedures such as easing formatting requirements and possibly carrying over peer-review to other journals could speed resubmission. Secondary publications can help maximize benefits from clinical trials; publications of secondary endpoints and subgroup analyses further define treatment effects and the patient populations most likely to benefit. These rely on data access, and although data sharing is becoming more common, many challenges remain. Beyond publication in medical journals, there is a need for wider knowledge dissemination to maximize impact on clinical practice. This might be facilitated through plain language summary publications. Social media, websites, mainstream news outlets, and other publications, although not peer-reviewed, are important sources of medical information for both the public and for clinicians. This underscores the importance of ensuring that the information is understandable, accessible, balanced, and trustworthy. This report is based on discussions held on December 2021, at the 18th Global Cardiovascular Clinical Trialists meeting, involving a panel of editors of some of the top medical journals, as well as members of the lay press, industry, and clinical trialists.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Inverse association between apolipoprotein C-II and cardiovascular mortality: role of lipoprotein lipase activity modulation.</h4><i>Silbernagel G, Chen YQ, Rief M, Kleber ME, ... Scharnagl H, Konrad RJ</i><br /><b>Aims</b><br />Apolipoprotein C-II (ApoC-II) is thought to activate lipoprotein lipase (LPL) and is therefore a possible target for treating hypertriglyceridemia. Its relationship with cardiovascular risk has not been investigated in large-scale epidemiologic studies, particularly allowing for apolipoprotein C-III (ApoC-III), an LPL antagonist. Furthermore, the exact mechanism of ApoC-II-mediated LPL activation is unclear.<br /><b>Methods and results</b><br />ApoC-II was measured in 3141 LURIC participants of which 590 died from cardiovascular diseases during a median (inter-quartile range) follow-up of 9.9 (8.7-10.7) years. Apolipoprotein C-II-mediated activation of the glycosylphosphatidylinositol high-density lipoprotein binding protein 1 (GPIHBP1)-LPL complex was studied using enzymatic activity assays with fluorometric lipase and very low-density lipoprotein (VLDL) substrates. The mean ApoC-II concentration was 4.5 (2.4) mg/dL. The relationship of ApoC-II quintiles with cardiovascular mortality exhibited a trend toward an inverse J-shape, with the highest risk in the first (lowest) quintile and lowest risk in the middle quintile. Compared with the first quintile, all other quintiles were associated with decreased cardiovascular mortality after multivariate adjustments including ApoC-III as a covariate (all P < 0.05). In experiments using fluorometric substrate-based lipase assays, there was a bell-shaped relationship for the effect of ApoC-II on GPIHBP1-LPL activity when exogenous ApoC-II was added. In ApoC-II-containing VLDL substrate-based lipase assays, GPIHBP1-LPL enzymatic activity was almost completely blocked by a neutralizing anti-ApoC-II antibody.<br /><b>Conclusion</b><br />The present epidemiologic data suggest that increasing low circulating ApoC-II levels may reduce cardiovascular risk. This conclusion is supported by the observation that optimal ApoC-II concentrations are required for maximal GPIHBP1-LPL enzymatic activity.<br /><br />© The Author(s) 2023.

<div><h4>Pre-treatment bicarbonate levels and decongestion by acetazolamide: the ADVOR trial.</h4><i>Martens P, Verbrugge FH, Dauw J, Nijst P, ... Dupont M, Mullens W</i><br /><b>Aims</b><br />Acetazolamide inhibits proximal tubular sodium and bicarbonate re-absorption and improved decongestive response in acute heart failure in the ADVOR trial. It is unknown whether bicarbonate levels alter the decongestive response to acetazolamide.<br /><b>Methods and results</b><br />This is a sub-analysis of the randomized, double-blind, placebo-controlled ADVOR trial that randomized 519 patients with acute heart failure and volume overload in a 1:1 ratio to intravenous acetazolamide (500 mg/day) or matching placebo on top of standardized intravenous loop diuretics (dose equivalent of twice oral maintenance dose). The primary endpoint was complete decongestion after 3 days of treatment (morning of day 4). Impact of baseline HCO3 levels on the treatment effect of acetazolamide was assessed. : Of the 519 enrolled patients, 516 (99.4%) had a baseline HCO3 measurement. Continuous HCO3 modelling illustrated a higher proportional treatment effect for acetazolamide if baseline HCO3 ≥ 27 mmol/l. A total of 234 (45%) had a baseline HCO3 ≥ 27 mmol/l. Randomization towards acetazolamide improved decongestive response over the entire range of baseline HCO3- levels (P = 0.004); however, patients with elevated baseline HCO3 exhibited a significant higher response to acetazolamide [primary endpoint: no vs. elevated HCO3; OR 1.37 (0.79-2.37) vs. OR 2.39 (1.35-4.22), P-interaction = 0.065), with higher proportional diuretic and natriuretic response (both P-interaction < 0.001), greater reduction in congestion score on consecutive days (treatment × time by HCO3-interaction <0.001) and length of stay (P-interaction = 0.019). The larger proportional treatment effect was mainly explained by the development of diminished decongestive response in the placebo arm (loop diuretics only), both with regard to reaching the primary endpoint of decongestion as well as reduction in congestion score. Development of elevated HCO3 further worsened decongestive response in the placebo arm (P-interaction = 0.041). A loop diuretic only strategy was associated with an increase in the HCO3 during the treatment phase which was prevented by acetazolamide (day 3: placebo 74.8% vs. acetazolamide 41.3%, P < 0.001).<br /><b>Conclusion</b><br />Acetazolamide improves decongestive response over the entire range of HCO3- levels; however, the treatment response is magnified in patients with baseline or loop diuretic-induced elevated HCO3 (marker of proximal nephron NaHCO3 retention) by specifically counteracting this component of diuretic resistance.<br /><br />© The Author(s) 2023.
