摘　　要：分析 51例左冠脉主干病变 (狭窄≥ 50 % )的冠心病患者。其中单纯左主干病变 8例 ,左主干合并其它冠脉病变 4 3例。并与非左主干病变的冠心病患者 2 1 0例进行比较。结果表明 :左主干病变组临床上多表现为不稳定性心绞痛 ,易发心梗 ,猝死率较高。但冠心病的易患因素及左室射血分数 ,在两组中差异无显著性。单纯左主干病变与非左主干病变者类似 ,但心绞痛发作时其心肌缺血更为严重。冠脉搭桥术可改善左主干病变患者的症状和预后。cases of coronary heart disease with the left main coronary artery (LM) Lesion (≥50% stenosis) were analyzed In 8 cases the LM Lesion was only involved,and in the others (43),the LM Lesions were accompanied by other branch lesions of coronary artery Compared with 210 cases of coronary heart disease without LM Lesions,in the LM Lesion groups,the patients clinically manifested severe unstable angina,and the incidences of acute myocardial infarction and sudden death were higher In the two groups of patients with and without LM Lesion The risk factor for coronary heart disease and left ventricular ejection fraction was unsignificantly different The clinical manifestations were similar in the two groups of patient with only LM Lesion and without LM Lesion But when angina onset myocardial ischemia is severe in the patients with only LM Lesion The coronary artery bypass graft may improve symptom and prognosis of patients with LM Lesion
