Key result
Coronary artery disease accounts for ~80% of sudden cardiac arrest, with nonischemic etiologies leading in young patients.
Why the study?
Although CAD accounts for 80% of sudden cardiac arrest overall, nonischemic structural heart diseases and electrical disorders are considered more prevalent in young patients, and recent shifts in CAD epidemiology prompted reassessment of the burden of CAD in young SCA.

Young patients with sudden cardiac arrest
Coronary artery disease (CAD) accounts for 80% of sudden cardiac arrest (SCA) overall [(1)][1], but nonischemic structural heart diseases and electrical disorders are considered more prevalent in young patients [(2)][2]. Considering recent shifts in CAD epidemiology [(3)][3], we hypothesized that
