Background: High-intensity physical activity has traditionally been discouraged in patients with hypertrophic cardiomyopathy due to concerns about triggering sudden cardiac death. However, current guidelines adopt a more liberal stance, and evidence on risk factors for exercise-related sudden cardiac death remains limited. This study investigated the clinical, morphological and genetic factors associated with high-intensity physical activity-related sudden cardiac death in hypertrophic cardiomyopathy.

Background: Although sudden cardiac death (SCD) generally occurs more frequently in men than in women, there are limited data on sex differences in SCD in patients with chronic heart failure (HF) across a range of left ventricular ejection fraction (LVEF).
Methods And Results: We examined sex differences in SCD incidence, timing, and risk factors in 4,683 patients with chronic HF (3,186 men, 1,497 women) from a multicenter prospective observational cohort study (CHART-2). Over a median follow-up of 8.

Objectives: Tangier disease (TD) is a rare autosomal recessive condition characterized by high-density lipoprotein (HDL) deficiency; involving symptoms of polyneuropathy, hyperplastic orange-yellow tonsils, vision disorder, and sudden cardiac death. The major clinical symptoms of TD may not all be co-present. This study evaluates patients diagnosed with TD in childhood to improve the possibility of early diagnosis of asymptomatic cases by reporting our patients' clinical characteristics in order to minimize delayed diagnosis and emphasize the importance of TD, easily detected by HDL measurement.

Background: Patients after kidney transplantation (KTx) in childhood show a high prevalence of cardiac complications, but the underlying mechanism is still poorly understood. In adults, myocardial fibrosis detected in cardiac magnetic resonance (CMR) imaging is already an established risk factor. Data for children after KTx are not available.

Aims: Ventricular arrhythmias (VAs), which can lead to sudden cardiac death, are the primary cause of mortality in patients with heart failure (HF). However, the precise mechanisms underlying these arrhythmias are not well understood. Recent studies have implicated tumour necrosis factor alpha-induced protein 3-interacting protein 3 (TNIP3) in pathological cardiac hypertrophy.
