RESUMEN
BACKGROUND: Not rarely we can find young people with acute myocardial infarction(AMI), many studies revealed they have fewer risk factors and less severe coronary angiographic abnormalities than middle and old aged group. METHODS: We studied clinical characteristics and coronary angiographic findings of 5 young men with AMI treated at Masan Koryo General Hospital from June 1986 June 1992. RESULTS: The age ranged between 19 and 32 years(mean 25.4). They had no other risk factors except cigrarette smoking(4 out of 5). Their coronary angiograms revealed no significant lesion in each infarct related artery. After discharge, all patient remained asymptomatic. CONCLUSION: AMI in young man might be related with cigarette smoking, and coronary artery spasm and/or thrombosis may play a significant role in its pathogenesis.
