急性心肌梗死经皮冠状动脉介入术后ST段改变对左室收缩功能的影响
Effect of ST-segment Changes after Percutaneous Coronary Intervention on Left Ventricular Systolic Function among Patients with Acute Myocardial Infraction
摘要
Abstract
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.关键词
