Clinical and Angiographic Characteristics of Exertion-Related Acute Myocardial Infarction

Abstract

These results show that exertion-related MIs occur in habitually inactive people with multiple cardiac risk factors. These individuals may benefit from modest exercise training and aggressive risk-factor modification before they perform vigorous physical activity.

Peculiarities of Coronary Artery Disease in Athletes

“…Giri et al reported that patients with an exertion-related MI were more likely to have risk factors including male sex, hyperlipidemia, hypertension and current cigarette smoking (59 % versus 37 % in non exertion-related MI) but in a population of which had known coronary artery disease and older than that of our study (Giri et al 1999). There were 28 cigarette smokers in a population of 42 patients in one study on unstable angina, SMI and SSD related to sport (Ciampricotti et al, 1990).…”

Exercise and Physical Activity in the Prevention and Treatment of Atherosclerotic Cardiovascular Disease

“…50 In some situations, regular physical activity actually reduces injury risk, as indicated by a recent consensus statement that physical activity is recommended to reduce the risk of fall injuries in older adults. 55 Vigorous physical activity acutely increases the risk of sudden cardiac death 56,57 and myocardial infarction 58,59 among individuals with both diagnosed and occult heart disease. A variety of congenital and acquired conditions such as hypertrophic cardiomyopathy, coronary artery anomalies, aortic stenosis, and cardiomyopathies are associated with sudden death during vigorous activity in children and young adults.…”

“…56,57 Exercise also transiently increases the risk of acute myocardial infarction. 58,59 Approximately 5% to 10% of myocardial infarctions are associated with vigorous physical activity. The relative risk of both exercise-related myocardial infarction and sudden death is greatest in individuals who are the least physically active and who were performing unaccustomed vigorous physical activity.…”

“…The relative risk of both exercise-related myocardial infarction and sudden death is greatest in individuals who are the least physically active and who were performing unaccustomed vigorous physical activity. [57][58][59] Sedentary adults should avoid isolated bouts of unaccustomed vigorous physical activity and should follow the standard recommendation to increase physical activity levels gradually over time. The possible value of this strategy is supported by the observation that the risk of exercise-related cardiac events is greatest in the least active individuals.…”

“…The possible value of this strategy is supported by the observation that the risk of exercise-related cardiac events is greatest in the least active individuals. 57,59 Because atherosclerotic CAD is the most frequent cause of exercise-related events, the incidence of such events is higher among patients with known atherosclerotic coronary disease. Among participants in cardiac rehabilitation programs, the average incidence of cardiac arrest, nonfatal myocardial infarction, and death is Ϸ1 for every 117 000, 220 000, and 750 000 patient-hours of participation, 64 respectively.…”
