摘　　要：目的：比较超声、同位素、磁共振三种方法检测心肌梗塞患者心肌存活性的准确性。方法：分别用多巴酚丁胺负荷超声试验（ＤＳＥ）、核素心肌显像（ＳＰＥＣＴ）、多巴酚丁胺负荷磁共振试验（ＤＥＭＲＩ）三种方法对１７例急性心肌梗塞患者的心肌存活性进行检测，比较三者的准确性、敏感性、特异性。结果：三种方法的准确性、敏感性、特异性：ＤＳＥ为７８％、８８％和８２％；ＳＰＥＣＴ为７８％、７５％和７６％；ＤＥ－ＭＲＩ为７８％、６３％和７０％。三种方法各指标差异并无统计学意义（Ｐ＞０．０５）。结论：本文认为在临床具体运用中可依照各方法的各自优缺点进行选择。Objective: To evaluate the safety,accuracy and feasibility of dobutamine stress echocardiography(DSE),dobutamine stress cine MR(DSMR)and SPECT in identification of viable myocardium after acute myocardial infarction. Methods :17 patients were studied with lowdose(510ug/kg/min)DSE,99mTcMIBI SPECT and lowdose(5ug/kgmin)DSMR.Their safety,accuracy and feasibility were compared. Results: With the standard of spontaneous recovery of left ventricular wall motion,the sensitivity,specificity and accuracy for DSMR for detecting the viable myocardium were 78%,63% and 70%,and that for DSE and NTG99mTcMIBI SPECT were 78%,88%,82% and 78%,75%,76%,respectively.No significant difference were found among these three methods(P>005). Conclusion: The three methods are the same in detecting the viable myocardium.
