Do sudden heart attacks increase with vigorous exercise? A community-based study investigated this issue and discovered that persons who habitually exercised vigorously had a reduced risk of sudden cardiac death as compared with persons who only occasionally exercised vigorously. One hundred thirty-three married men who experienced out-of-hospital cardiac arrest were chosen for the study. They were classified according to their usual amount of activity and the amount of activity at the time of the cardiac arrest. All appeared healthy prior to the heart attacks. The benefits outweighed the risks for men at the upper levels of habitual high-intensity activity. Their overall risk was 40 percent of that of sedentary men.
