Abstract

In at least one-half of the patients with angina or ischemia and nonobstructive coronary arteries undergoing coronary function testing, coronary artery spasm (CAS) is detected. CAS is associated with an adverse prognosis regarding recurrent complaints and ischemic events. Current treatment options are mainly focused on the complaints, not on the underlying pathophysiological process. In this review we discuss available evidence regarding the presence, amount, and morphology of atherosclerosis in CAS patients. The reviewed evidence confirmed that atherosclerosis and vulnerable plaque characteristics are often detected in patients with CAS. The amount of atherosclerosis is higher in patients with focal CAS compared with patients with diffuse CAS. Severity of atherosclerosis is associated with the presence of CAS and the prognosis in CAS patients with atherosclerotic stenosis is worse. Therefore, CAS patients with atherosclerosis might benefit from targeted atherosclerotic treatment. Longitudinal studies are needed to elucidate the exact relation between atherosclerosis and CAS.
