Autopsy-Defined Causes of SAD by Race. Autopsy etiologies of SAD by race after review of comprehensive medical records, EMS run sheets, and comprehensive autopsy data including post-mortem chemistry and toxicology. First % is of total presumed SCDs and second % is of cause of death category. MINOCA accounted for 3% of SAD in Asians and Blacks and 0% in Whites (p=0.03). CAD accounted for 43% in Blacks and 61% in Whites (p<0.05) while cardiomyopathy accounted for 34% of SAD in Blacks and 17% in Whites (p=0.02). Primary electrical disease accounted for 14% of SAD in Hispanics and 2% in Whites (p<0.01).

CAD indicates coronary artery disease; MINOCA, myocardial infarction without obstructive coronary arteries; SAD, sudden arrhythmic death

*Adjusted for age and sex vs. reference White

†Other cardiac arrhythmic causes included acquired long QT syndrome (LQTS), bicuspid aortic valve, cardiac implantable external device (CIED) concern and/or failure, mitral valve prolapse, and critical aortic stenosis (AS).
