Spontaneous coronary artery dissection: a review of the etiology and available treatment options

Abstract

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction and sudden cardiac death. We present a case of a 36-year-old female runner who was successfully thrombolysed for acute anterior ST elevation myocardial infarction. Coronary angiography revealed spontaneous dissection of the left anterior descending and diagonal arteries. The patient was treated medically with warfarin and dual antiplatelet therapy. Repeat angiography at 8 weeks showed significant angiographic improvement. Exercise stress testing at 10 months was normal and allowed a return to exercise. At 28 months the patient is asymptomatic and fully active. A review of the etiology and available treatment options is presented.
