Could a hidden artery condition explain heart attacks in young women?

This study investigates whether fibromuscular dysplasia (FMD), a condition that causes abnormal growth in artery walls, is more common in people who have had a spontaneous coronary artery dissection (SCAD) — a tear in a heart artery that can cause a heart attack, often in young women without typical risk factors. Researchers will analyze blood samples for genetic markers and use imaging to check for FMD in multiple artery beds. The goal is to confirm the suspected association and uncover genetic determinants that might explain why SCAD happens.
