摘　　要：目的:评价经皮冠状动脉介入治疗(PCI)术对近期S-T段抬高心肌梗死(STEMI)患者左心室结构和功能的影响。方法:51例已确诊为近期STEMI的患者,全部行冠状动脉照影检查,25例行便死相关动脉(IRA)PCI术,其后予以常规药物治疗,26例未行介入治疗直接进行药物治疗;术前或用药前应用多普勒超声测量ESV、EDV、LVEF、WMAS、E、A、E/A、Ei、Ai、Ei/A、SV等指标,并随访3个月,进行复查。结果:介入治疗组术后3个月ESV、EDV、WMAS、Ai较术前分别下降了26.5％(P<0.01)、15.6％(P<0.01)、41％(P<0.01)、26.6％(P<0.05),LVEF、Ei/Ai较术前提高了17.8％(P<0.01)、35.6％(P<0.01)。对照组随访3个月,ESV、EDV分别较初期提高了10.8％、9.6％(P均<0.05),LVEF降低了10.0％(P<0.05),两组间Ai、Ei/Ai、ESV、EDV、LVEF、WMAS均有非常显著差异(P均<0.01)。结论:PCI术可改善近期心肌梗死患者的左室功能及预后。Objective: To assess the effects of percutaneous coronary intervention (PCI) on left ventricular structure and function in patients with non-acute myocardial infarction. Methods: A total of 51 patients with non-acute myocardial infarction were observed by coronary artery angiographies, in which 25 patients were performed PCI, 26 patients were given medicine. ESV^ EDV, LVEF> WMAS and Ei/Ai were measured by Doppler echocardiography before PCI or medicine treatment and followed-up for three months. Results: Compared with the follow-up examination, the values of EDV and ESV decreased 15- 6%, 26. 5% (P<0. 01) respectively, and the values of LVEF elevated 17. 8% (P<0. 01) in the patients with PCI patients; But the values of EDV and ESV elevated 9. 6%, 10. 8% respectively, the LVEF decreased 10. 0% (P<0. 05 all) in the control patients. There was significant difference on Ai,Ei/Ai, EAT, EDV, LVEF, WMAS (P<0. 01 all) between PCI and control patients. Conclusion: PCI of coronary related with infarction possess good effect on left ventricular structure and function in patients with non-acute myocardial infarction.
