Overview
Epidemiology and Demographics
Based on the relatively limited data that is currently available, the estimated incidence of SCAD is approximately 800 new cases per year in the US.[1] SCAD has a strong predilection for young women with no or minimal traditional atherosclerotic risk factors. Studies indicate that SCAD accounts for approximately 25% of women aged < 50 who present with MI.[2] SCAD should be highly suspected in any young subject presenting with acute myocardial ischemia, but without traditional risk factors for coronary artery disease (CAD).The left anterior descending artery (LAD) is the most commonly affected artery.[3][4] Although multivessel SCAD has been reported, single vessel SCAD is much more common. In women LAD is frequently involved[3] while in men right coronary artery is involved more often. Men tend to present at a slightly later age and also with evidence of CAD risk factors.
Observational studies have reported that SCAD is common among young women during their peripartum period[5] or in association with use of oral contraceptives. About 80% of SCAD cases reported so far have occurred in young women, especially those taking oral contraceptives (OCPs) or those in the peripartum period.[6][7][8] Possible mechanisms underlying increased prevalence of SCAD in this population include: changes in the arterial wall media due to increasing hormone levels, shear stress during labor, fragmentation of reticulin fibers, loosening of ground substance, and hypertrophy of smooth muscle.[9]
