Myocardial Infarction Triggered by Marijuana Use

Chronic marijuana use has been increasingly linked to cardiovascular events, though reports of acute myocardial infarction in young adults without traditional risk factors remain limited. A 24-year-old man with a 9-year history of daily marijuana use presented with acute chest pain. Emergency evaluation revealed anterior ST-segment elevation myocardial infarction with 100% proximal left anterior descending coronary artery occlusion, treated successfully with percutaneous intervention. Intravascular ultrasound showed isolated plaque rupture in an otherwise normal coronary tree. This case highlights marijuana's potential role in precipitating acute coronary events in young adults without traditional risk factors, supported by intravascular imaging findings.
