摘　　要：目的:探讨异舒吉(isoket)对小剂量多巴酚丁胺超声负荷试验(LDDSE)的影响。方法:将39例研究对象依据冠脉造影的结果分为3组:对照组(CON)12例、冠心病1组(CAD1)15例和冠心病2组(CAD2)12例,其中CAD2行LDDSE+isoket,其余两组行LDDSE,以冠脉介入性治疗(PCI)后室壁运动改善的结果作为评价LDDSE的标准。结果:isoket可以明显增加心率,降低收缩压,但对舒张压影响轻微。CAD2组存活心肌的检出率和敏感性明显高于CAD1组。结论:isoket可提高LDDSE存活心肌检出率。Objective： To observe the effect of isoket on low-dose dobutamine stress echocardiography（LDDSE）.Methods： 39 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 12 patients. Among the three group,the LDDSE＋isoket was done in CAD2,while the LDDSE 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 LDDSE.Results： Isoket could increase heart rate and decrease SBP, but could hardly affect DBP. The rate detecting viable myocardium and sensitivity were improved significantly in group CAD2. Conclusion： LDDSE combined with isoket was benefit for detecting viable myocardium.
