作者分析了222例冠心病患者冠状动脉造影结果。其中左冠状动脉主干狭窄12例,占5.4%,左主干开口处病变程度较同时累及的其它支相对轻。左主干分叉处病变程度与同时累及的其它支相近。左主干狭窄不能根据临床表现、体检及心电图等无创性检查作出明确诊断。冠状动脉旁路手术可以延长患者的生命。
The authors analyzed the results of coronary angiography in 222 patients with coronary heart disease. The left main coronary artery stenosis in 12 cases, accounting for 5.4%, the lesion in the left main opening than the other branches involved in the same time relatively light. The degree of lesion at the left main bifurcation was similar to that of other branches involved at the same time. Left main stenosis can not be based on clinical manifestations, physical examination and ECG noninvasive examination to make a clear diagnosis. Coronary artery bypass surgery can extend the life of patients.
