Most deaths due to cardiac arrest are in older adults, particularly those with coronary artery disease. Cardiac arrest is the leading cause of death in young athletes, but the incidence of it is unclear. Perhaps 1 in every 50,000 sudden cardiac deaths a year occurs in young athletes.
Other cardiac abnormalities that can cause sudden death are heart valve abnormalities, electrical conduction abnormalities of the heart, and rupture of the aorta (the large blood vessel that carries the blood from the heart to the body). Another cause of sudden death among athletes is Marfan syndrome (Fig. 2).
