Impact of Renin‐Angiotensin System Inhibitors on Long‐Term Clinical Outcomes of Patients With Coronary Artery Spasm

摘要

BackgroundCoronary artery spasm (CAS) is a well‐known endothelial dysfunction, and a major cause of vasospastic angina (VSA). The renin–angiotensin system (RAS) is known to be closely associated with endothelial function. However, there are only a few studies that investigated the impact of RAS inhibitor on long‐term clinical outcomes in VSA patients.
