冠心病诊断指标的多变量研究

A Study on Multiple Variants of Noninvasive Diagnostic Techniques in Coronary Artery Disease

本文从６４例病人的临床资料中选出常用七种无创检查指标，共１４种变量，逐一量化后与冠脉造影结果进行比较。发现典型症状和ＥＣＧ适用于定性诊断，ＵＣＧ和Ｄ－ＥＣＧ可对程度作出一定判断。各变量综合评分与冠脉造影之间有良好的复相关，Ｒ值为０．８８８。其敏感性为９３％，特异性为８０％，阳性预测值为８７％，阴性预测值为８９％。综合评分的诊断意义在于节约诊断费用，易于评价无创指标。

The routine seven noninvasive technique has been used in 64 patients.14 variants choosen from them have been quantiated one by one.It was shown that the typical syndrome and ECG were the best parameters for qualitative diagnosis,UCG and Dipyridamole-ECG had certain quantitative meaning.The analytical marking of 14 variants had very good correlation with coronary angiogram,R value was 0.888 and it’s sensitivity,specificity, positive predictive value, negative predictive value were 93%,80%,87%,89% respectively.It is cost saving by noninvasive techniques,the analytical marking made the diagnosis objective convenient.
