目的探讨急性心肌梗死冠状动脉早期再通对左心室功能的影响。方法用彩色多普勒超声心动图观察急性心肌梗死60例。其中包括静脉溶栓成功组18例,直接PTCA组12例,常规治疗组30例;正常对照组20例。结果 急性心肌梗死各组左心室收缩及舒张功能均较正常对照组明显减低(P<0.05及P<0.01)。溶栓组与常规治疗组比较左心室舒张功能明显改善(P<0.05),直接PTCA组与常规治疗组比较左心室收缩及舒张功能明显改善(P<0.05及P<0.01),直接PTCA组与溶栓组比较左心室收缩功能明显改善(P<0.05)。结论直接PTCA和早期溶栓治疗能改善左心室功能,并且PTCA优于溶栓治疗。
Objective To investigate the effect of early recanalization of coronary artery on left ventricular function in patients with acute myocardial infarction. Methods Sixty cases of acute myocardial infarction were observed by color Doppler echocardiography. Including intravenous thrombolysis in 18 cases of successful group, 12 cases of direct PTCA group, 30 cases of conventional treatment group; 20 cases of normal control group. Results The left ventricular systolic and diastolic functions in each group were significantly lower than those in normal control group (P <0.05 and P <0.01). The left ventricular diastolic function was significantly improved in the thrombolysis group compared with the conventional treatment group (P <0.05), and the left ventricular systolic and diastolic function was significantly improved in the direct PTCA group compared with the conventional treatment group (P <0.05 and P <0.01) Thrombolytic group significantly improved left ventricular systolic function (P <0.05). Conclusion Direct PTCA and early thrombolytic therapy can improve left ventricular function, and PTCA is superior to thrombolytic therapy.
