摘　　要：目的探讨急性心肌梗死(AMI)经皮冠状动脉介入(PCI)后ST段改变对患者左室收缩功能的影响。方法 58例ST段抬高型前壁AMI接受PCI患者,术后1 h ST段回落≥50%49例(回落组),<50%9例(非回落组),分别于术后1个月及6个月行二维超声心电图及应变率成像(SRI)检查。结果术后1个月、术后6个月回落组左室射血分数(LVEF)、左室平均收缩峰值应变率(mPSSR)均高于非回落组(P<0.05)。结论急性心肌梗死PCI术后ST段迅速回落对左室收缩功能恢复的影响具有重要意义。Objective To explore the effect of ST-segment changes after percutaneous coronary intervention（PCI） on left ventricular systolic function among patients with acute myocardial infraction（AMI）.Methods Fifty eight anterior AMI patients with ST-segment elevation underwent PCI,in which there were 49 cases of 1-hour postoperative ST-segment resolution ≥50%（ST-segment decline group） and 9 cases 〈50%（non-ST-segment decline group）.All the patients were examined by two-dimensional echocardiography and strain rate imaging（SRI） one month and six months after operation,respectively.Results Left ventricular ejection fraction（LVEF） and mean peak systolic strain rate（mPSSR） of ST-segment decline group were both higher than those of non-ST-segment decline group one month or six months after operation（P〈0.05）.Conclusion Rapid resolution of ST-segment is of great significance to the recovery of left ventricular systolic function in patients with AMI after PCI.
