A 63-year-old female exhibited non-Q wave anterior myocardial infarction when operated with general anaesthesia. Introducing ergonovine provocation into the normal right coronary artery induced ST elevations in II, III, _aV_F and V_<4-6> with chest pain. Chest pain and electrocardiographic change disappeared following the injection of isosorbide dinitrate into the coronary artery. Specimens of the cardiac muscle did not show vascular abnormality. In this case, the mechanism of acute myocardial infarction could be based on the depression of coronary reserve caused by multivessel vasospasm.}, pages = {171--173}, title = {Myocardial Infarction Caused by Coronary Vasospasm under General Anaesthesia}, volume = {40}, year = {1992} }
