A 24-year-old male student had three myocardial infarctions, one prior to and two following the angiographic documentation of normal coronary arteries. A spontaneous episode of variant angina prompted repeat coronary angiography, during which intravenous ergonovine caused spasm of the left anterior descending coronary artery, transient ST-segment elevation, and ischemic chest pain; the previously normal right coronary artery was found to be occluded proximally. This constellation of clinical and angiographic findings suggests that coronary spasm can cause acute myocardial infarction as well as variant angina.
一名24岁的男学生发生了三次心肌梗死，一次在冠状动脉造影显示正常之前，两次在冠状动脉造影显示正常之后。一次自发性变异型心绞痛发作促使再次进行冠状动脉造影，在此期间静脉注射麦角新碱导致左前降支冠状动脉痉挛、短暂性ST段抬高和缺血性胸痛；发现先前正常的右冠状动脉近端闭塞。这一系列临床和血管造影结果表明，冠状动脉痉挛可导致急性心肌梗死以及变异型心绞痛。
