Abstract

We reported the case of vasospastic angina unresponsive to lifestyle modifications and intense medical treatment, in which symptoms improved after coronary stent placement. The patient had episodes of ST-segment elevation. Vasospasm was induced by a provocation test and relieved by nitroglycerin, leading to a diagnosis of Coronary Vasomotion Disorders. Optical coherence tomography showed vasospasm only in segments with atherosclerotic lesions. This case underscores the importance of early intervention for atherosclerotic lesions, since acute coronary syndrome (ACS) can occur without significant stenoses. Interventional treatment should be considered for drug-resistant vasospasms unresponsive to optimal medical therapy to improve outcomes.
