A 46-year-old male patient with atypical angina pectoris appeared to have an important elongated stenosis of the left main coronary artery on coronary arteriography, and slight irregularities in the left anterior descending, circumflex, and right coronary arteries. A saphenous vein bypass graft to the left anterior descending artery was performed, and this relieved the patient's symptoms. Postoperative coronary arteriography demonstrated a widely patent left main coronary artery and graft. The original narrowing of the left main coronary artery was probably caused by spasm and the source of the patient's anginal symptom.
一名46岁患有非典型心绞痛的男性患者，在冠状动脉造影检查中显示左主冠状动脉有一处重要的长段狭窄，左前降支、回旋支和右冠状动脉有轻微不规则病变。对左前降支进行了大隐静脉搭桥术，术后患者症状缓解。术后冠状动脉造影显示左主冠状动脉和移植血管通畅。左主冠状动脉原有的狭窄可能是由痉挛引起的，也是患者心绞痛症状的根源。
