Marijuana and Coronary Dissection: A Case Report and Review of Literature.

Spontaneous coronary artery dissection (SCAD) is a cardiac emergency and an uncommon cause of acute coronary syndrome (ACS) with a higher predominance in younger women. It is a non-traumatic, non-atherosclerotic lesion found to be associated with pregnancy, inflammatory disorders, connective tissue diseases and substance abuse. Our patient was a young woman with a chronic marijuana smoking history who was found to have a NSTEMI. Initial angiogram showed triple vessel disease involving left anterior descending artery (LAD), left circumflex artery (LCX) and obtuse marginal artery (OM). A repeat angiogram notably showed spontaneous progression with dissection in all three vessels attributable to substance abuse. We present you this rare occurrence of triple vessel SCAD secondary to marijuana with a literature review and discussion.
