Abstract
Epidemiological studies have documented that habitual physical activity reduces the population incidence of coronary heart disease, including myocardial infarction (MI) and cardiac death.1 On the other hand, vigorous physical activity can also acutely and transiently increase the risk of both of these cardiac events.2-5 Between 4% and 15% of MIs occur during or soon after vigorous exertion,6 making exertion one of the most common triggers of acute MI. Such events appear more frequent in patients with diabetes and habitually sedentary individuals,2 but little else is known about who develops an exertion-related cardiac event. Most studies of exertion-related sudden death cannot develop a clinical picture of the victims because of small sample sizes.4,5,7 The current study compared the clinical characteristics of patients who experienced an exertion-related MI with those who experienced MI not related to exertion.Keywords
