摘　　要：目的观察经皮冠状动脉介入治疗(PCI)前后的冠心病患者左心功能改善与其病变严重程度的关系。方法选择我院心内科成功实施冠状动脉介入治疗的住院患者102例,根据冠脉造影结果用累积积分法显示冠脉狭窄严重程度,根据积分分为高分组和低分组,术前及术后3个月行心脏多普勒超声检查,分别检测EF、E峰、A峰及E/A比值,并进行比较。结果高分组、低分组EF值、E/A比值术后较术前明显提高,且高分组EF值、E/A比值的改善明显高于低分组。结论冠心病患者介入治疗后左心功能较术前有明显改善,且冠脉病变越重,左心功能改善越明显。Objective To investigate the relationship between left ventricular function and severity of coronary artery lesions in CHD patients before and after PCI. Methods 102 patients who were treated with PCI were classified as high score group（〉30） and low score group（〈30） according to the results of coronary angiography CAG, the left ventricular diastole function and left ventricular ejection fraction EF was analyzed before and after treatment with PCI for 3 months by Dapple rechocardiography, and EF and E/F were measured. Results The levels of EF after treatment with PCI for 3months in low score group and high score group were significantly higher than those before treatment with PCI. The degree of development of EF after treatment with PCI for 3 months in high score group was higher than that in low score group. Conclusion The levels of left ventricular ejection fraction after PCI have obvious improvement whether the coronary artery lesions are severe or not before the operation, and the effect for the patients whose CHD is severer on the improvement of systolic function of left ventricle is more remarkable.
