ABSTRACT
Objective To observe the effect of Isoket on standard dobutamine stress echocardiography(DSE).Methods Thirty-seven patients were divided into three groups according to the results of quantitative coronary angiography(QCA)the control group(CON) including 12 patiens,the coronary artery disease group 1(CAD1) including 15 patients,and the coronary artery disease group 2(CAD2) including 10 patients.Among the three group,the DSE+Isoket was done in CAD2,while the standard DSE was done in the other two groups.The improvement of segments of left ventricular after percutaneous transluminal intervention(PCI) was looked as the standard evaluating DSE.Results Isoket could increase heart rate and decrease systolic blood pressure,but could hardly affect diastolic blood pressure.The rate of biphysic response was 62.5% in group CAD1,and the sensitivity of detecting viable myocardium was 61%,while the specificity was 76%.In group CAD2,the rate of biaphysic response was 72.2% ,and the sensitivity of detecting viable myocardium was 82%,while the specificity was 88%.The rate detecting viable myocardium and sensitivity was improved significantly in group CAD2.Conclusions DSE combined with Isoket was beneficial for detecting viable myocardium.
