Abstract:
Objective To study the clinical application s of intravenous myocardial contrast echocardiography (IMCE) in assessing myocardial reperfusion in acute myocardial infarction (AMI) using intravenously infused Levovist. Methods IMCE was performed in 13 AMI patients before and after thrombolytic therapy. The power Doppler signals of the myocardial segments were analyzed and the time-amplitude curves were plotted during Levovist infusion and incremental triggering. The maximal amplitude score (A), the mean ascending slope of the curve(?) and the product of A?? were measured. All patients were followed up for 3 months. And then IMCE indices were estimated for left ventricular function. Results There was a significant increase in A,? and A?? between before and after thrombolysis(P
