摘要
目的:99Tcm-MIBI心肌灌注显像和心电图与冠状动脉造影的对照及临床诊断意义。方法:患者均于住院期间作99Tcm-MIBI心肌灌注显像与冠状动脉造影检查,静息心肌灌注显像前描记静态心电图,运动显像的同时记录心电图。结果:50例冠心病患者99Tcm-MIBI心肌灌注显像和心电图与冠状动脉造影对照,两者总的符合率分别为94.0%及80.0%(P<0.05),两者对陈旧性心肌梗塞的检出率相似,而99Tcm-MIBI静态与运动心肌灌注显像对检出冠状动供血不足比静息与运动心电图特异性高。结论:99Tcm-MIBI心肌灌注显像对陈旧性心肌梗塞病变的检出率和对病变范围的估价优于心电图,是判断心肌缺血敏感、可靠、无创性的检查方法。
Objective:To compare the diagnostic value between 99Tcm-MIBI myocardial perfusion(MPI) and electrocardiogram(ECG) /coronary angiogram(CAG) in patients with old myocardial infarction(OMI).Methods:Fifty patients(mean age 55.4 years old)underwent MPI and ECG and CAG in one month.Results:① In comparison with CAG,the coincident rate in MPI and ECG were 94.0% and 80.0% respectively(P<0.05).②The detecting rate were similar between MPI and ECG for OMI.③The comparison between rest MPI and stress ECG,street myocardial imaging has high specificity for diagnosing coronary artery disease.Conclusions:In comparison with CAG,the coincident rate of MPI is higher than in ECG in the diagnosis of orientation,area,and detecting rate of OMI.MPI was a noninvasive,sensitivity,valuable and reliable method for detecting myocardial ischemia。
