Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia. Comprehensive modification of established AF risk factors combined with dietary interventions and breaking deleterious habits has been shown to reduce AF burden and recurrence. Numerous AF risk factors, such as diabetes, obesity or hypertension can be partially related to dietary and lifestyle choices. Therefore, dietary interventions

Background and Aims Pathogenic variants in the desmoplakin (DSP) gene are associated with the development of a distinct arrhythmogenic cardiomyopathy phenotype not fully captured by either dilated cardiomyopathy (DCM), non-dilated left ventricular cardiomyopathy (NDLVC), or arrhythmogenic right ventricular cardiomyopathy (ARVC). Prior studies have described baseline DSP cardiomyopathy genetic, inflammatory

Cardiovascular diseases persist as a global health challenge that requires methodological innovation for effective drug development. Conventional pipelines relying on animal models suffer from high failure rates due to significant interspecies variation between humans and animal models. In response, the recently enacted Food and Drug Administration Modernization Act 2.0 encourages alternative approaches

Marfan syndrome (MFS) is a hereditary connective tissue disorder with an estimated prevalence of 1:5000–1:10 000 individuals. It is a pleiotropic disease characterized by specific ocular, cardiovascular, and skeletal features. The most common cardiovascular complication is aortic root dilatation which untreated can lead to life-threatening aortic root dissection, mainly occurring in adult patients

BACKGROUND AND AIMS A cardiovascular disease polygenic risk score (CVD-PRS) can stratify individuals into different categories of cardiovascular risk, but whether the addition of a CVD-PRS to clinical risk scores improves the identification of individuals at increased risk in a real-world clinical setting is unknown. METHODS The Genetics and the Vascular Health Check Study (GENVASC) was embedded within

Emerging evidence indicates that chemical exposures in the environment are overlooked drivers of cardiovascular diseases (CVD). Recent evidence suggests that micro- and nanoplastic (MNP) particles derived largely from the chemical or mechanical degradation of plastics might represent a novel CVD risk factor. Experimental data in preclinical models suggest that MNPs can foster oxidative stress, platelet

Background and Aims A variety of maternal heart conditions are associated with abnormal placentation and reduced foetal growth. However, their impact on offspring’s long-term cardiovascular health is poorly studied. This study aims to investigate the association between intrauterine exposure to pre-existing maternal cardiovascular disease (CVD) and offspring CVD occurring from infancy to early adulthood

BACKGROUND AND AIMS In the AEGIS-II trial (NCT03473223), CSL112, a human apolipoprotein A1 derived from plasma that increases cholesterol efflux capacity, did not significantly reduce the risk of the primary endpoint through 90 days versus placebo after acute myocardial infarction (MI). Nevertheless, given the well-established relationship between higher low-density lipoprotein cholesterol (LDL-C)

Extracorporeal life support (ECLS) has been increasingly used in the treatment of severe infarct-related cardiogenic shock in the last decade. The randomised ECLS-SHOCK trial demonstrated no benefit of early routine use on 30-day all-cause death. We herein present mid-term results. At 1-year follow-up, there were no significant differences in all-cause or cardiovascular mortality, neurologic outcome

Background and aims Endometriosis, a systemic gynecological disease affecting 10% of women in reproductive age, shares pathophysiological characteristics with cardiovascular disease. However, data on the relationship between endometriosis and cardiovascular outcomes are scarce, prompting this study to address the knowledge-gap. Methods Using Danish nationwide registries, women diagnosed with endometriosis

Background and aims The optimal antithrombotic therapy in patients with device-detected atrial fibrillation (DDAF) is unknown. Concomitant vascular disease can modify the benefits and risks of anticoagulation. Methods These pre-specified analyses of the NOAH-AFNET 6 (n=2534 patients) and ARTESiA (n=4012 patients) trials compared anticoagulation to no anticoagulation in patients with DDAF with or without

Background and Aims Peripartum cardiomyopathy (PPCM) remains a serious threat to maternal health around the world. While bromocriptine, in addition to standard treatment for heart failure, presents a promising pathophysiology-based disease-specific treatment option in PPCM, the evidence regarding its efficacy remains limited. This study aimed to determine whether bromocriptine treatment is associated

BACKGROUND AND AIMS The detection of cancer therapy-related cardiac dysfunction (CTRCD) by reduction of left ventricular ejection fraction (LVEF) during chemotherapy usually triggers the initiation of cardioprotective therapy. This study addressed whether the same approach should be applied to patients with worsening of global longitudinal strain (GLS) without attaining thresholds of LVEF. METHODS

BACKGROUND AND AIMS To improve upon the estimation of 10-year cardiovascular disease (CVD) event risk for individuals without prior CVD or diabetes mellitus in the Asia-Pacific region by systematic recalibration of the SCORE2 risk algorithm. METHODS The sex-specific and competing risk-adjusted SCORE2 algorithms were systematically recalibrated to reflect CVD incidence observed in four Asia-Pacific

BACKGROUND AND AIMS Overtesting of low-risk patients with suspect chronic coronary syndrome (CCS) is widespread. The acoustic-based coronary artery disease (CAD) score has superior rule-out capabilities when added to pre-test probability (PTP). FILTER-SCAD tested whether providing a CAD score and PTP to cardiologists was superior to PTP alone in limiting testing. METHODS At six Danish and Swedish outpatient

BACKGROUND AND AIMS The question of when and how to treat truly asymptomatic patients with severe aortic stenosis (AS) and normal left ventricular (LV) systolic function is still subject to debate and ongoing research. Here, the results of extended follow-up of the AVATAR trial are reported (NCT02436655, clinical trials.gov). METHODS The AVATAR trial randomly assigned patients with severe, asymptomatic

BACKGROUND AND AIMS The role of biomarker testing in the management of obstructive hypertrophic cardiomyopathy (oHCM) is not well defined. This pre-specified analysis of SEQUOIA-HCM (NCT05186818) sought to define the associations between clinical characteristics and baseline concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (hs-cTnI), and

Background and Aims Long-term safety and efficacy of mavacamten in patients with obstructive hypertrophic cardiomyopathy (HCM) are unknown. MAVA-LTE (NCT03723655) is an ongoing, 5-year, open-label extension study designed to evaluate the long–term effects of mavacamten. Methods Participants from EXPLORER-HCM (NCT03470545) could enrol in MAVA-LTE upon study completion. Results At the latest data cut-off

Background and Aims Current guidelines recommend 6 hours of solid food and 2 hours of clear liquid fasting for patients undergoing cardiac procedures with conscious sedation. There are no data to support this practice, and previous single centre studies support the safety of removing fasting requirements. The objective of this study was to determine the non-inferiority of a no fasting strategy to fasting

Background and Aims Glycoprotein (GP) IIb/IIIa inhibitors are recommended in acute myocardial infarction (AMI) for bailout treatment in case of angiographic microvascular obstruction (MVO), also termed no-reflow phenomenon, after percutaneous coronary intervention (PCI) with, however, lacking evidence (class IIa, level C). Methods The investigator-initiated, international, multicenter REVERSE-FLOW

Background and Aims Neoatherosclerosis is a leading cause of late (>1 year) stent failure following drug-eluting stent implantation. The role of biodegradable (BP) versus durable polymer (DP) drug-eluting stents on long-term occurrence of neoatherosclerosis remains unclear. Superiority of biodegradable against durable polymer current generation thin-strut everolimus-eluting stent (EES) was tested by

Background and Aims Deep learning applied to electrocardiograms (ECG-AI) is an emerging approach for predicting atrial fibrillation or flutter (AF). This study introduces an ECG-AI model developed and tested at a tertiary cardiac centre, comparing its performance with clinical and AF polygenic scores (PGS). Methods ECG in sinus rhythm from the Montreal Heart Institute were analysed, excluding those

Background and Aims The microvascular resistance reserve (MRR) is a novel invasive index of the microcirculation, which is independent of epicardial stenoses, and MRR has both diagnostic and prognostic implications. This study investigates whether MRR is associated with health status outcomes by revascularization in patients with moderate coronary stenoses. Methods Consecutive patients with stable

Background and aims: Cardiogenic shock (CS) remains the primary cause of in-hospital death after acute coronary syndromes (ACS), with its plateauing mortality rates approaching 50%. To test novel interventions, personalized risk prediction is essential. The ORBI (Observatoire Régional Breton sur l’Infarctus) score represents the first-of-its-kind risk score to predict in-hospital CS in ACS patients

Background and aims Non-high-density lipoprotein cholesterol (HDL-C) provides an estimate of lipid-associated risk and is a secondary treatment target after myocardial infarction (MI). The aim was to study the relationship between non-HDL-C levels after MI and risk of adverse outcomes. Methods From the SWEDEHEART registry, 56,262 patients with MI were included. Outcomes were major adverse cardiovascular

Background and Aims Randomized clinical trials (RCTs) assessing semaglutide reported reductions of systolic blood pressure (SBP) in trial populations with baseline blood pressure in the normotensive range. This study aimed to determine whether this SBP reduction is greater in hypertensive groups. Methods Individual patient data (IPD) from three RCTs examining the effect of semaglutide 2.4 mg on body

Background and Aims Patients with congenital heart disease (CHD) form a high-risk subgroup for infective endocarditis (IE), necessitating tailored prevention and treatment strategies. However, comprehensive nationwide data comparing IE characteristics and outcomes in patients with and without CHD, including children, are sparse. This study aims to address this gap in knowledge.
