急性心肌梗塞后冠脉内支架植入术对左心室收缩功能的影响

Influence of coronary artery stenting on left ventricular function after myocardial infarction

目的:观察心梗后冠脉内支架植入术对左心室功能的影响。方法:75例急性心肌梗塞后患者35例行冠脉内支架植入治疗(支架组),40例行静脉内溶栓治疗(溶栓组),比较两组梗塞相关血管开通率,左室射血分数(LVEF)值。结果:梗塞相关动脉开通率:冠脉内支架术组100%,显著高于溶栓组的60%,P<0.05。90dLVEF:支架术组(57.5±6.7)%明显高于溶栓组的(42.0±4.3)%,P<0.05。结论:心梗后冠脉动内植入支架治疗可有效开通梗塞相关动脉,明显改善左心功能。

Objective： To observe the influence of coronary artery stenting on left ventricular function （LVEF） after myocardial infarction （MI）. Methods： The 35 cases were treated with coronary artery stenting （stenting group）, 40 cases were treated with intravenous thrombolysis （thrombolysis group）, left ventricular ejection fraction （LVEF） were compared between two groups. Results： Patency rate of infarction relate -artery was 100% in stenting group, it was more than that of thrombolytic group （60%）, P〈0.05 . The 90th day after therapy LVEF of coronary stcnting group was （57.5±6.7）%, it was significantly higher than that of thrombolysis group （60 %）, P〈0.05. Conclusion： Coronary stent implantation effectively improve heart function after myocardial infarction.
