title: Probably myocardial infarction in a 14-year-old boy.
abstract: After vigorous physical activity a 14-year-old boy from a family with a strong history of cardiac disease developed symptoms consistent with a myocardial infarction, a relatively rare event in this age group. Isoenzyme patterns of creatine kinase and lactate dehydrogenase were consistent with the occurrence of an infarction.
