摘要
本文对３１例正常人、３４例心肌缺血及１７例心肌梗塞进行靶心图定量分析，并与断层显像及靶心图定性分析进行了比较。结果表明：三种方法诊断心肌缺血的灵敏度与特异性依次为８８．２％、９１．２％和９４．１％（Ｐ＞０．０５）；９３．５％、８３．９％和８３．９％（Ｐ＜０．０５）。定量分析对心梗周围缺血心肌壁段的检出率明显高于后两种方法（Ｐ＜０．０１）。因此，靶心图定量分析为诊断冠心病提供了一种客观、定量、特异和灵敏的方法。
Abstract In this study,the99mTc-MIBI Bullseyes of 31 healthy persons, 34 Patients with myocardial ischemis and 17 patients with myocardial infarction were quantitatively analysed,and compared with the results of myocardial tomography analysis and Bullseye qualitative analysis. The sensitivitis of the three methods were 88. 2%,91. 2 %and 94. 1 % respectively(P>0. 05),and the specificities were 93. 5 %, 83. 9 % and 83. 9 % respectively(P<0. 05). In the segment numbers of detected ischemic myocardium,quantitative analysis were much more than that of the other two methods(P<0. 01). So Bullseye quantitative analysis was an objective,quantitative,specific and sensitive method for diagnosis of CAD.
