Abstract:
Objective To study the clinical application of intravenous myocardial contrast echocardiography(IMCE) in assessing myocardial reperfusion by using intravenously infused Levovist before and after percutaneous coronary interventions(PCI). Methods IMCE was performed in 20 patients with coronary artery disease(CAD) before and after PCI. 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), mean ascending slope of the curve(?) and product of A?? were measured. All the patients were followed up 3 months later for assessing IMCE items of left ventricular function. Results A significant increase was showed in A,? and A?? after PCI(P
