Abstract
Spontaneous coronary artery dissection (SCAD) is a well-recognized cause of acute coronary syndrome (ACS) which can lead to myocardial infarction and sudden death. Unlike typical atherosclerosis, SCAD operates through distinct pathophysiology, affecting both individuals with and without conventional cardiovascular risk factors. We present a case of a young female presented with retrosternal chest pain radiating to the left arm, mimicking ACS symptoms with mildly elevated troponin levels, and slightly reduced left ventricular ejection fraction (45%). Subsequent evaluation using coronary angiography unveiled a Type 2A SCAD. A comprehensive computed tomography angiography (CTA) of her entire body revealed findings suggestive of fibromuscular dysplasia (FMD) affecting multiple arteries in different sites. Our case entailed the successful management of a young female patient with SCAD stemming from FMD.
