ABSTRACT

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
