SCAD should be strongly considered in young patients presenting with acute myocardial ischemia without traditional risk factors, requiring urgent angiography for diagnosis and tailored management.
SCAD warrants consideration in young AMI patients without risk factors; leaves open need for prospective trials on tailored strategies.
Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia with complex pathophysiology. This paper reviews the major diagnostic and therapeutic issues of this rare but important disease. The diagnosis of SCAD should be strongly considered in any patient who presents with symptoms suggestive of acute myocardial ischemia, particularly in young subjects without traditional risk factors for coronary artery disease (especially in young women during the peripartum period or in association with oral contraceptive use). Urgent coronary angiography is indicated to establish the diagnosis and to determine the appropriate therapeutic approach. The decision to pursue medical management, percutaneous coronary intervention, or surgical revascularization is based primarily on the clinical presentation, extent of dissection, and amount of ischemic myocardium at risk.
