Objective:To explore the cardiac protective effect of integrative therapy in acute myocardial infarction(AMI) with elevated ST segment after reperfusion.Methods:Sixty-four AMI patients who having received decimalization by thrombolysis were assigned to two groups by retrospective analysis,36 patients in the treated group and 28 in the control group.Both were treated by intravenous administering of urokinase for thrombolysis,and to the treated group,intravenous dripping of Xueshuantong Injection(血栓通注射液,XST) was added.Serum levels of myocardial associated enzymes were monitored before treatment and at various time points after thrombolysis, and the heart function parameters were detected with color echocardiography before treatment and on the 7th and 14th day of treatment.The patients were followed up for 6 months to observe the incidence of cardiac events. Results:The differences between groups at the peak and peak appearing time of creatine kinase and creatine kinase isoenzyme were not significant.All the heart function parameters on the 7th and 14th day in the treated group were improved and superior to those at the corresponding time points in the control group(P<0.05,P<0.01).Incidence of some heart events in the treated group within the 6-month follow-up period was lesser than that in the control group (P<0.05).Conclusion:XST Injection could provide effective protection for the heart after reperfusion.
