Key result
Sudden cardiac death accounts for ~66% of US heart disease deaths, predominantly with advanced LV dysfunction.
Why the study?
Despite recent reductions in cardiac mortality from other causes, the incidence of sudden cardiac death remains high with minimal decline in the last decade.
Answers are grounded in this paper and cite their sources.
Reveals that sudden cardiac death causes 460,000 annual US deaths, primarily linked to advanced left ventricular systolic dysfunction, highlighting persistent mortality despite other cardiac gains.
Heart disease is the leading cause of death in the US with 700,000 deaths annually, of which 460,000 are attributable to sudden cardiac death (SCD). SCD is usually attributed to ventricular fibrillation (VF). Despite recent reductions in cardiac mortality from other causes, the incidence of SCD remains high with minimal decline in the last decade. The large majority of patients who suffer life-threatening ventricular arrhythmias have advanced left ventricular (LV) systolic dysfunction.

Jeyaraj et al. (2005) conducted a review in Sudden cardiac death. Sudden cardiac death accounts for 460,000 of the 700,000 annual US heart disease deaths, occurring predominantly in patients with advanced left ventricular systolic dysfunction.
