摘 要 目的：探讨利声显心肌声学造影(IMCE)在AMI早期确诊及评价溶栓疗效中的价值。方法：11例AMI患者溶栓治疗前后行IMCE检查，分析利声显输注和递增触发时的心肌多普勒信号，并描绘时间-强度曲线，测量平台期心肌显影强度(A)、曲线上升平均斜率(β)及A*β乘积在治疗前后的变化。结果：溶栓后A、β及A^. β值均显著增加(P<0.05～0.01)，而溶栓失败者A仍≤2分。结论：IMCE为AMI的诊断及床旁评价溶栓疗效提供了简便、安全和可靠的新途径。

ABSTRACT Objective:To study the reliability ofintravenous myocardial contrast echocardiography(IMCE)in assessing myocardial reperfusionin acute myocardial infarction(AMI)using intravenously infused levovist.Methods：IMCE wasperformed in 11 AMI patients before and after thrombolytic therapy.The power Dopplersignals of the myocardial segments were analyzed and the time-amplitude curves wereplotted during levovist infusion and incremental triggering.The maximal amplitudescore(A),the mean ascending slope of the curve(β)and the product of A*β weremeasured.Results:There was a significant increase in A、β and A*β after thrombolysis(P<0.05～0.01),whilein no reperfusion patients,A was still below 2 score.Conclusion:IMCE offers a simple andreliable approach to the non-invasive assessment of thrombolytic therapy in patients withAMI.
