摘    要:目的 :探讨多巴酚丁胺负荷试验中左室舒张功能的参数变化及其在冠心病诊断中的意义。方法 :对 18例正常人和 30例冠心病患者进行多巴酚丁胺负荷超声心动图检查 ,分析比较静息状态与峰值负荷状态下两组左室舒张功能各参数的变化情况。结果 :多巴酚丁胺负荷后 ,两组心率、收缩压均明显增加 ,组间比较有明显差异 ;左室舒张早期峰值血流速度 (E)和左室舒张早期血流传播速度 (RFP)在对照组表现为增加 ,在冠心病组为减低 ;冠心病组出现局部室壁运动异常 (RWMA) 2 5例 ,对照组有 1例出现 RWMA。结论 :多巴酚丁胺负荷试验中左室舒张功能的参数变化是反映冠心病心肌缺血的敏感指标 ,可为冠心病诊断提供有力帮助。

关 键 词:多巴酚丁胺负荷试验   左室舒张功能   冠状动脉疾病

Abstract:AIM:To investigate the variation of left ventricular diastolic function indexes during dobutamine stress echocardiography. METHODS:Changes of left ventricular diastolic function indexes were observed in 18 normal subjects and 30 patients with coronary artery stenosis. RESULTS:In both groups dobutamine induced similar increases in heart rate and systolic blood pressure;dobutamine caused increases in control subjects and decreases in patients in peak early filling velocity(E) and rate of flow propagation (RFP);during the test,25 patients had wall motion abnormalities,and ischemia occurred to one of the control subjects. CONCLUSION:During dobutamine stress test,an abnormal response of left ventricular diastolic function is a sensitive index for myocardial ischemia and of high value in detecting coronary artery diseases.
Keywords:dobutamine stress test  left ventricular diostolic function  coronary disease
