摘　　要：本文对90例冠心病运动^(99)锝-甲氧异丁异腈(^(99m)Tc-MIBI)心肌断层显象和心电图运动试验、二维超声心动图(2DE)进行比较,评价运动^(99m)=Tc-MIBI 心肌断层显象对冠心病的诊断价值。表明:对冠心病心肌缺血的诊断,前者优于后二者(P<0.01);心肌断层显象对冠心病心肌梗塞的后壁、前侧壁、心尖部定位诊断优于心电图(P<0.01);运动^(99m)Tc-MIBI 心肌断层显象对冠心病心绞痛诊断较敏感,对冠心病心肌梗塞定位诊断较全面,对冠心病心律失常型诊断较准确。Quantitative stress 99m_(TC-MIBI) Myocardical tomography was evaluated propestively as compared with electrocardiography (ECG) and two dimensional echocadrdiography (2DE) in 90 patients with coronary heart disease.The results showed that Tc-99 myocardial tomography was superior to ECG and 2DE in the diagnosis of myocardial ischemia in coronary heart disease(P<0.01).For localization of myocardial infarction in the lateral wall,posterior wall and apex of the heart,myocardial tomograhy was better than ECG(P<0.01) and so was it more sensitive in the diagnosis of angina pectoris in coronary heart disease.Thus,it provides high diagnotic accuracy for arrhythmic coronary heart dis- ease.
