摘 要:以冠状动脉造影为标准,在39例患者评价了多巴酚丁胺 ̄99m锝-MIBl心肌断层显像对冠心病的诊断价值。结果显示其诊断冠心病的敏感性和特异性分别为92.9%和90.9%;诊断冠状动脉单支、双支、三支病变的敏感性分别为90.9%、87.5%和100%。17例多支病变中15例(敏感性88.2%)被检出有多支血管供血区域心肌受累。研究中无严重副反应。结论:多巴酚丁胺 ̄99m锝-MIBI心肌断层显像作为冠心病无创诊断方法是安全可行的。he value of dobutamine ̄99mTc-MIBI SPECT(Dobu-ECT)for detecting coronary artery disease(CAD)was assessed in 3 9 patients. Compared with coronary angiography,the overall sensitivity and specificity of DObu- ECT for detecting CAD were 92.9%and 90.9%, Of 13 patients with CAD without myocardial infarction,the sensitivity of Dobu-ECT was 84.6%. In detecting CAD with single, double or triple vessel diseases,the sensitivity of Dobu- ECT was 90.9%,87.5%and 100%respectively. Further- more,88.2%of the patients(15/17)with multivessel(two or three vessels)diseases were correctlv iden- tified as having multivessel involvement.For detecting CAD,the sensitivity and specificity of dobutamine ECG were 53.5%and 82%, No serious side effects were observed in the studv. The results showed that Dobu-ECT is a feasibie, safe and noninvasive method for diagnosing CAD.
