Epidemiologic features of myocardial infarction in young patients

Acute myocardial infarction (AMI) in persons under the age of 45 years is uncommon. To determine the clinical features in young patients presenting with AMI, we include 38 patients with mean age 35 years who survive from myocardial infarction. This disease is almost associated with cardiovascular risk factors, the most common of which are tobacco abuse (90%) and diabetes (20%). The coronary arteries are most often normal (40%) or single vessel (33%). In hospital complications are the same as in the older adult but the prognosis seems to be better.
