So, this paper reports on the diagnosis of variant angina by beta-blocker provocation test and the case of subendocardial infarction induced by this test. This study reports with literature and investigation about the following case A 45-year-old man with a history of recurrent episode of typical angina on the early morning for the past 20 days. He was administrated beta-blocker given by oral route, and on the next morning there was chest pain as same degree as before, Holter EKG displayed ST segment elevation and ventricular tachycardia. It was confirmed focal spasm on coronary angiography, ST segment elevation on EKG, and newly developed hypokinesia on left ventriculogram and followed-up echocardiography. When the chest pain is absent, EKG was normal. And we confirmed that the elevation of cardiac enzyme was absent as a result of serial follow up study.
