^(99m)Tc-MIBI心肌断层显像潘生丁介入试验对冠心病诊断价值的观察

Evaluation of Dipyridamole ^(99m)Tc-MIBI Myocardial Tomography Imaging in the Diagnosis of Coronary Heart Disease

报道27例正常对照者和78例冠心病(CHD)患者99m Tc-MIBI静息心肌显像及潘生丁介入后心肌显像,并与心电图(ECG)、平板运动试验作对比。结果表明:99mTc-MIBI心肌灌注断层显像对缺血性心脏病诊断的阳性率为92.3％,高于平板运动试验的81.8％、ECG的74.3％,有非常显著性差异(P<0.01),特异性为89.4％。

Seventy-eight patients with coronary heart disease and 27 control subjects were studied by both rest and dipyridamole 99mTc-MIBI myocardial imaging and the data were compared with the results of ECG and treadmill exercise tests. The results showed that the positive rate of 99mTc-MIBI myocardial perfusion tomography imaging to diagnose ischemic heart disease was 92. 3%,which was higher than treadmill exercises tests(81. 8%)and ECG(74. 3%) ,the differences were significant(P<0. 01),and the specificity was 89. 4%.
