摘要
以冠状动脉造影为标准,对39例冠脉狭窄≥50%的冠心病人与13例冠脉狭窄<50%或腔径正常的临床可疑冠心病人作为"正常"对照,用多巴酚丁胺负荷超声心动图(Dobu-Echo)和心电图(Dobu-ECG)试验对冠心病的诊断价值进行了评价。发现Dobu-Echo的敏感性为92.3%,特异性为84.6%,准确度为90.4%;而Dobu-ECG的敏感性为30.8%,特异性76.9%,准确度42.3%。试验中未发现严重不良反应发生。结果认为:Dobu-Echo是安全、准确性好的无创性冠心病诊断试验,可推广临床应用。
Abstract To estimate the diagnostic value of dobutamine stress echocardiography (Dobu-Echo) and electrocardiography (Dobu-ECG) in coronary artery disease (CAD), 52 cases presenting for coronary angiography (39 cases with CAD and 13 cases without CAD) were prospectively studied. The sensitivity of Dobu-Echo was 92.3%, specificity 84.6% and accuracy 90.4% while the sensitivity of Dobu-ECG was 30.8% , specificity 76.9% and accuracy 42.3 % . No major adverse effects was found during the tests. We conclude that Dobu-Echo is a safe and accurate test for noninvasive identifying CAD and can be used widely.
