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.

Study confirms the implication of Mib1 mutations in non-compaction cardiomyopathy

Non-compaction cardiomyopathy is a heart condition caused by defects that arise during fetal development and can have diverse health impacts in affected individuals, including sudden cardiac death.

Expanding screening could help prevent sudden cardiac death in young people with HCM

Nearly nine in ten cases of sudden cardiac death (SCD) due to hypertrophic cardiomyopathy (HCM) in young people are preceded by symptoms, ECG abnormalities or a positive family history, according to a new study published this week in the open-access journal PLOS ONE by Erik Börjesson of Sahlgrenska University Hospital, Sweden, and colleagues.

Air pollution may trigger arrhythmias in healthy adolescents

Breathing particulate matter (i.e., tiny particles suspended in the air) air pollution may trigger irregular heart rhythms (arrhythmias) in healthy teenagers, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

New software application predicts the likelihood of genetic mutation in dilated cardiomyopathy

Scientists at the CNIC and Hospital Universitario Puerta de Hierro in Majadahonda have developed a software application that predicts the likelihood that a case of dilated cardiomyopathy is caused by a genetic mutation. The research was carried out in collaboration with hospitals in Spain, Italy, and the Netherlands.

Polygenic risk score identifies coronary artery disease patients at risk for sudden cardiac death.

Researchers in the Smidt Heart Institute at Cedars-Sinai are one step closer to identifying patients at highest risk for developing sudden cardiac death - an electrical malfunction in the heart that causes it to stop beating.

Ultra-precise gene therapy technologies could edit or silence faulty genes causing fatal heart diseases

An injectable cure for inherited heart muscle conditions that can kill young people in the prime of their lives could be available within a few years, after an international team of researchers were announced as the winners of the British Heart Foundation's Big Beat Challenge.

Impaired cardiac metabolism linked to increased risk of fatal arrhythmias or sudden cardiac death

Adults with abnormal heart metabolism are up to three times more likely to experience life-threatening arrhythmias (an irregular heart rhythm), and MRI techniques could be used to detect the condition and predict future sudden cardiac death (SCD), according to a small, but rigorous study led by Johns Hopkins Medicine researchers.
