Abstract

A 61-year-old man was admitted to our hospital due to chest pain on both rest and effort. After the computed tomography coronary angiography, coronary stenosis was recognized at segment 3. Because inferior ischemia on stress myocardial perfusion scintigraphy with 201 thallium chloride induced by adenosine was found, we planned to perform the coronary intervention. After control coronary angiography, no significant stenosis was found in the right coronary artery. Intracoronary acetylcholine testing disclosed diffuse spasm at segment 4, whereas intracoronary ergonovine administration documented the total spasm at segment 3. After the intracoronary administration of nitrate, we diagnosed him with coronary spastic angina without organic stenosis. <
