Sudden cardiac death during running is mainly caused by an acute myocardial infarction and coronary artery disease. Other diseases like myocarditis are rarely documented. ⋯ At autopsy a 50% stenosis of the descending branch of the left coronary artery, and histologically an active myocarditis were observed (Dallas-classification). The endured extreme stress of the marathon probably resulted in arrhythmias and in sudden cardiac death.
