Genotype and arrhythmic risk in dilated cardiomyopathy.
European heart journal·October 13, 2026·PMID 42864989
Why it mattersRisk stratification in DCM currently relies heavily on LVEF, but this registry analysis shows that genetic subtype independently predicts arrhythmic and heart failure events, even when LVEF is preserved. Identifying high-arrhythmogenic gene carriers may refine decisions about ICD implantation and closer monitoring.
