Abstract
Prinzmetal's variant angina occurred in a 52‐year‐old man 10–11 h after the ingestion of alcohol, when blood levels of alcohol decreased almost to the zero level. Coronary arteriograms revealed significant narrowing in the left circumflex artery and the left anterior descending artery and minimal wall irregularity in the right coronary artery; however, both exercise and pharmacologic stress tests were negative. A withdrawal from an acute exposure to alcohol was discussed as a possible causative mechanism of the alcohol‐induced Prinzmetal's variant angina in this case.
