[Sudden death in athletes].
In order to study the etiologies and mechanisms in sports-related sudden death, the author selected 198 cases from the world literature which met the following criteria: subjects were less than 40 years of age and in good physical condition, death occurred at the latest 1 hour after the physical activity, there was no known heart disease, and an autopsy had been performed. In spite of the heterogeneous character of those subjects included in this study and numerous biases, the following results were obtained: in some cases, the mechanism underlying the sudden death could be confirmed by autopsy (massive myocardial infarction, rupture of the aorta, cerebral hemorrhage), and in others it appeared highly probable (atheromatous or congenital coronary artery lesions, hypertrophic cardiomyopathies). Finally, in a certain number of cases, the observed abnormalities could only be seen as presumptive evidence (mitral prolapse, sequelae of myocarditis, or the presence of toxic agents). Failure to establish a precise diagnosis at autopsy occurred in only 22 cases (11%), however, amphetamine drug presence was discovered in 7 of these cases. Approximately one-half of the group studied revealed atheromatous coronary artery lesions (29% of cases) or congenital lesions (17.5%) especially involving the origin of the left coronary artery. These were followed in frequency by the hypertrophic cardiomyopathies. Mitral valve prolapse and WPW syndrome were rarely encountered. Extracardiac causes included rupture of the aorta (4.5%) and cerebral vascular accidents (5%).
