摘　　要：目的探讨ATP负荷试验99mTc-MIBI心肌显像对冠心病诊断的临床价值。方法对83例确诊或可疑冠心病行ATP负荷试验99mTc-MIBI心肌显像和静息显像,1周后行冠脉造影(SCA)进行研究对照。结果ATP负荷试验99mTc-MIBI心肌显像诊断冠心病敏感性为93.8%(60/64),特异性为84.2%(16/19),符合率为91.5%(76/83);静息心肌显像敏感性为76.6%(49/64),特异性为68.4%(13/19),符合率为74.7%(62/83)。结论ATP负荷试验99mTc-MIBI心肌显像,提高了对冠心病的诊断率,对诊断冠心病具有重要意义。Objective To explore diagnostic value of adnosine triphosphate（ATP） stress ^99mTc-MIBI myocardial imagingon coronary heart disease（CHD）. Methods Eighty-three with final or suspieionse diagnosis of CHD were performed with ATP stress ^99mTc-MIBI myocardial imaging and resting myocardial imaging.A week later the patients were performed with selective coronary angiography（SCA）. Results The sensitivity of adnosine triphosphate stress ^99MTc-MIBI myocardical imaging on diagnosis of CHD was 93.8 % （60/64 ）, specificity was 84.2 % （10/19）, coincidence was 91.5 % （76/83 ）. The sensitivity of resting myocardial imaging was 76.6% （49/64） ,specificity was 68.4% （13/19）, coincidence was 74.7% （62/ 83）. Conclusion The ATP stress ^99mTc-MIBI myocardial imaging improves the diagnostic rate of CHD and plays an imlportant role in diagnosing CHD.
