title: [Acute myocardial infarct in a young cocaine user].
abstract: In patients less than 40 years of age, acute myocardial infarction (AMI) has special clinical and pathophysiologic characteristics. Its prevalence varies between 5 and 10%. In such patients, AMI associated with chronic cocaine abuse has a non-negligible prevalence of 6%. The purpose of this report is to describe the case of a 24-year old male patient with smoking habits and chronic abuse of cocaine and hallucinogenic drugs. This patient developed clinical, enzymatic and electrocardiographic criteria of anterior AMI, two hours after the ingestion of an LSD-like hallucinogenic drug. The coronary angiography revealed a critical stenosis of the medium segment of the left anterior descendent artery, and a pre-stenotic aneurysmatic dilatation. In order to determine the etiology of the aneurysm, various laboratory and histologic tests were performed. The results of these were normal. We review the pathophysiology, clinical manifestations and prognosis of cocaine-associated AMI.
