摘　　要：目的:探讨成功经皮冠脉成形术(Percutaneous coronary angioplasty,PCI)术后左室收缩功能改善程度与冠状动脉狭窄程度的关系。方法:108例成功PCI的冠心病(CHD)住院患者,根据术前冠状动脉造影显示冠状动脉狭窄程度用累积积分法分为高分组和低分组,术前及术后1个月行心脏超声检查,测量射血分数EF值。结果:低分组、高分组术后EF值均明显高于术前(P<0.01,P<0.05)。结论:成功PCI对冠状动脉病变较轻或严重患者左室收缩功能均有明显改善。Objective：To investigate the relationship between improving degree of left ventricle contractile function after PCI and degree of coronary stricture.Methods：108 CHD patients that were successfully executed PCI were divided into high-score group and low-score group according to degree of coronary stricture.The ejection fraction（EF） were measured by ultrasonography of heart before PCI and 1 month after PCI.Results：The EF of patients in high-score group and low-score group after PCI were all obviously higher than that before PCI（P0.01,P0.05）.Conclusions：Successful PCI could obviously improve the left ventricle contractile function not only for patients with mild but also severe pathological changes of coronary artery.
