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。
In this paper, we selected seven kinds of noninvasive indexes commonly used in clinical data of 64 patients, a total of 14 variables, one by one quantitative comparison with coronary angiography results. Typical symptoms and ECGs were found to be useful for qualitative diagnosis, and UCG and D-ECG were somewhat judgmental. There was a good complex correlation between the composite score of each variable and coronary angiography, with an R value of 0.888. The sensitivity was 93%, the specificity was 80%, the positive predictive value was 87%, the negative predictive value was 89%. The diagnostic significance of comprehensive score is to save diagnostic costs, easy to evaluate noninvasive indicators.
