Why the study?
Men with fibromuscular dysplasia may be at higher risk for recurrent SCAD, highlighting a need to better understand the disease pathophysiology and develop medical therapies in this population.
This case highlights the rare occurrence of recurrent SCAD in a young male with fibromuscular dysplasia, demonstrating that conservative medical management can lead to complete angiographic vessel healing.
May indicate higher SCAD recurrence risk in men with fibromuscular dysplasia; leaves open need for sex-specific surveillance studies.
Spontaneous coronary artery dissection (SCAD) is a rare presentation of acute coronary syndrome characterized by a tearing of the wall of the epicardial coronary artery, leading to myocardial ischemia. SCAD predominantly affects young and middle-aged women, but young men without significant cardiovascular risk factors can also present with the disease. In the setting of fibromuscular dysplasia, men may be at a higher risk for recurrence. We present the case of a young man with a history of fibromuscular dysplasia and prior SCAD in the diagonal branch and right posterolateral artery who presented with exertional chest pain. Further evaluation revealed a recurrent SCAD of the distal right coronary artery despite being on conservative management with aspirin and beta-blockers. There is a need to study the pathophysiology of fibromuscular dysplasia and SCAD in men further and develop medical therapies to treat recurrent SCAD.
