The term sudden cardiac death refers to natural death from cardiac causes, heralded by abrupt loss of consciousness within one hour of the onset of acute symptoms.

Strength training shows no added arrhythmia risk in people with arrhythmogenic cardiomyopathy

People living with arrhythmogenic cardiomyopathy (ACM), a heritable heart condition that can significantly increase risks for sudden cardiac death, are advised to avoid high-intensity aerobic exercise.

Younger heart patients benefit from implantable cardioverter-defibrillators in CMR GUIDE trial

An implantable cardioverter-defibrillator did not improve the primary endpoint overall in the CMR GUIDE trial but younger patients appeared to benefit, according to results presented in a Hot Line session today at ESC Congress 2026 and published simultaneously in JAMA.

This 29-year heart study tracked what happens after smokers quit

Long-term data from the Copenhagen City Heart Study linked both current and former smoking with a higher risk of sudden cardiac death, with risk rising alongside cumulative smoking exposure. Among former smokers, risk generally declined with longer time since quitting and approached that of never smokers only after prolonged abstinence.

Modifiable cardiovascular risk factors linked to unstable coronary artery plaques

Cardiovascular risk factors are linked to higher risk of heart disease, but it has been unknown how they are related to abrupt closure of the coronary arteries leading to heart attack and sudden cardiac death.

Scientists link genetic spelling mistakes to sudden cardiac death

Scientists have found that the 'sudden' cardiac death condition related to high profile deaths or major medical episodes of sports stars including Fabrice Muamba, Christian Erikson and Mark-Vivian Foe has numerous linked gene variations, or "spelling mistakes", which highlights a potentially treatable vulnerability.

New molecular mechanism identified in common inherited heart disease

A study led by the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), working in collaboration with an international research team, has identified a new molecular mechanism involved in hypertrophic cardiomyopathy, the most common inherited cardiovascular disease.

Extreme temperatures pose growing danger to heart health

Extreme heat and cold are growing cardiovascular risks that can trigger heart attacks, strokes, heart failure and sudden cardiac death, according to a recent scientific statement by experts at Weill Cornell Medicine and other leading institutions.

Study reveals right ventricle better tolerates oxygen loss during cardiac arrest

A study led by scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) provides new insights into ventricular fibrillation (VF), the most dangerous type of cardiac arrhythmia.

New wristband algorithm detects sudden cardiac arrest with high accuracy

A smart-technology wearable wristband device may be able to automatically detect cardiac arrest, which could lead to faster medical assistance and increased survival odds when cardiac arrest occurs outside of a hospital, according to new research published today in Circulation: Arrhythmia and Electrophysiology, a peer-reviewed scientific journal of the American Heart Association.

Study improves prediction of dangerous outcomed from hypertrophic cardiomyopathy

A sweeping international study has identified ways to detect patients who are at serious risk of sudden death, heart failure or other dangerous outcomes from heart thickening known as hypertrophic cardiomyopathy.

New model improves outcome predictions for patients with hypertrophic cardiomyopathy

Findings from a study supported in part by the National Institutes of Health (NIH) have identified a new model for predicting outcomes for hypertrophic cardiomyopathy (HCM), a heart condition with a prevalence of 1 in 500 people and a frequent cause of sudden cardiac death.

New genetic link found for sudden cardiac death in young people

Short QT syndrome is a genetic disease that leads to sudden cardiac death at a young age. Mutations in the SLC4A3 gene, which regulates bicarbonate-chloride exchange, were recently described as a potential cause. An international research team, including a group from Ruhr University Bochum, Germany, investigated this possibility.

Exercise may be safer for children with heart conditions

Physical activity in children and teenagers with cardiomyopathy (conditions that affect the heart muscle's structure and function, impairing its ability to pump or fill effectively), as well as children with implantable cardioverter-defibrillators (ICDs) may be safer than previous research suggested, according to a new scientific statement from the American Heart Association, published today in the Association's flagship peer-reviewed journal Circulation.

TikTok favors non-experts even when doctors post better sudden cardiac death content

Healthcare professionals made higher-quality and more credible TikTok videos about sudden cardiac death, but non-healthcare creators attracted more reshares, favourites, and overall engagement. Sentiment did not differ significantly between groups, suggesting that better information quality does not automatically translate into wider reach.
