Sudden Cardiac Death News and Research

RSS

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.

How zinc deficiency could worsen heart inflammation and what that means for patients

This review examines how zinc regulates inflammatory and redox signaling pathways involved in myocarditis and pericarditis, highlighting mechanisms such as NF-κB inhibition and the redox zinc switch. The authors conclude that maintaining optimal zinc status may support cardiovascular resilience, while emphasizing that clinical translation requires further targeted trials.

Schools and families may not be fully prepared to respond to teen cardiac emergencies

Sudden cardiac arrest can happen to anyone, including teens, and a new national poll suggests many schools and families may not be fully prepared to respond.

Gene therapy targeting connexin 43 shows promise across inherited heart diseases

University of California San Diego-led team has discovered that restoring a key cardiac protein called connexin‑43 in a mouse model can dramatically improve heart function and extend survival in several inherited forms of arrhythmogenic cardiomyopathy (ACM)

Study reveals the hidden toll of sudden cardiac death in type 1 and type 2 diabetes

A Danish nationwide study found that people with type 1 and type 2 diabetes have markedly higher rates of sudden cardiac death than the general population, especially at younger ages. At age 30, people with diabetes lose many years of life, with several of those years specifically attributable to sudden cardiac death.

Genetic variant linked to higher heart failure risk in children with myocarditis

A genetic variant is likely putting some children suffering with myocarditis - inflammation of the heart muscle - at higher risk of developing heart failure, which can be fatal, according to a study published today in Circulation Heart Failure.

Study reveals unequal burden of sudden cardiac death among colorectal cancer survivors

A new research paper was published in Volume 12 of Oncoscience on November 7, 2025, titled "Temporal trends and disparities in sudden cardiac death among colorectal cancer patients: A nationwide study."

Sudden cardiac death risk is sharply elevated in people with diabetes

The risk of sudden cardiac death is higher both for people with type 1 and type 2 diabetes, according to a large study published in the European Heart Journal today (Thursday). The increase in risk is especially noticeable among younger adults.

Northwestern scientists create new genetic risk score to improve prediction of arrhythmia

In a new Northwestern Medicine study, scientists have developed a more precise genetic risk score to determine whether a person is likely to develop arrhythmia, an irregular heartbeat that can lead to serious conditions such as atrial fibrillation (AFib) or sudden cardiac death.

More frequent use of electrocardiograms could help prevent sudden cardiac death

Many young people who suffered sudden cardiac death had recently sought medical care. More frequent use of electrocardiograms (ECG) could help prevent such cases, according to researchers at the University of Gothenburg.

Female bodybuilders face higher risk of sudden cardiac death, study reveals

A 16-year study in the European Heart Journal found that sudden cardiac death (SCD) was the leading cause of death among female bodybuilding athletes. While overall mortality was half that of men, women still had a markedly higher SCD risk than other female athletes, highlighting the need for stricter health oversight and PED monitoring.

Study reveals high sudden cardiac death rates in female bodybuilders

Sudden cardiac death is responsible for an unusually high proportion of deaths in female bodybuilders worldwide, according to research published in the European Heart Journal today (Tuesday).

Intensive sports in adolescents trigger complex heart adaptations

Adolescent athletes' cardiovascular system may adapt to increased cardiorespiratory fitness by increasing blood pressure, arterial stiffness and heart growth, a new study shows.

'Resistin like molecule gamma' punches holes into heart cells after myocardial infarction

Nina Kumowski, MD, of the Department of Radiology and Center for Systems Biology at Massachusetts General Hospital, is the lead author and Matthias Nahrendorf, MD, PhD of the Department of Radiology and Center for Systems Biology at MGH, is the senior author of a paper published in Science, "Resistin-like molecule γ attacks cardiomyocyte membranes and promotes ventricular tachycardia."

Neutrophil peptide found to trigger dangerous heart arrhythmias

Following injury from a heart attack, immune cells called neutrophils release a peptide that punctures stressed heart cells and destabilizes their electrical activity.

ICD treatment does not lower death risk in patients with abnormal ECG after myocardial infarction

Prophylactic implantable cardioverter defibrillator therapy did not reduce mortality in patients with a prior myocardial infarction, persistent moderate left ventricular systolic dysfunction and abnormal ECG markers, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

Trial shows no meaningful gains with mavacamten in nonobstructive hypertrophic cardiomyopathy

Mavacamten treatment at 48 weeks was not associated with significant improvements in patient-reported health status or peak oxygen consumption compared with placebo in patients with symptomatic nonobstructive hypertrophic cardiomyopathy, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025 and simultaneously published in New England Journal of Medicine.
