Abstract
Marijuana is known to have been used for medicinal and recreational purposes for thousands of years. Although marijuana has some diverse effects on cardiovascular system, there is insufficient knowledge concerning acute myocardial infarction (AMI) associated with marijuana and its underlying mechanism. We report the case of a 26 year-old young man suffering from ST-elevated AMI caused by marijuana abuse, which was successfully treating with percutaneous coronary intervention. It should be kept in mind that marijuana could be one of the most probable causes of AMI observed in apparently healthy young persons who use this drug.
