Overview

Spontaneous coronary artery dissection should be differentiated from other causes of acute coronary syndrome. Features suggestive of spontaneous coronary artery dissection include myocardial infarction in young women (age ≤50), absence of traditional cardiovascular risk factors, peripartum state, history of fibromuscular dysplasia, and history of connective tissue disorder or systemic inflammatory disorder.

Differential Diagnosis

Albeit an infrequent condition, spontaneous coronary artery dissection (SCAD) should be included in the differential diagnosis of acute coronary syndrome, particularly among young women with risk factors such as vasculopathy, pregnancy, connective tissue disorder, systemic inflammation, strenuous exercise, emotional stress, or recreational drug use. While demographic and angiographic characteristics may be useful in differentiating SCAD from other causes of myocardial ischemia, intracoronary imaging such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) may be required for establishing a definitive diagnosis.

Features that raise the index of suspicion for SCAD include:[1]
