Overview
Causes
The exact etiology of spontaneous coronary artery dissection (SCAD) remains elusive and appears to be multifactorial. It has been postulated that the phenotypic expression of SCAD may occur as a result of predisposing factors compounded by precipitating stressors.[1] Among the conditions associated with the occurrence of SCAD, fibromuscular dysplasia (FMD) and takotsubo cardiomyopathy (TCM) have been postulated to have a causal relationship with SCAD.
Fibromuscular Dysplasia
FMD is a non-atherosclerotic vasculopathy characterized by thickening, fibrosis, and disarray of the arterial wall that primarily affects small and medium-sized vessels. The association between FMD and SCAD has been well described,[2][3][4][5] and the biological proof of causation has been supported by histopathologic reports.[6][7][8] It has been suggested that the presence of FMD may weaken the artery architecture and lead to aneurysm formation or coronary dissection.[9]
Takotsubo Cardiomyopathy
