摘要
本文对121例冠心病人和对照组进行潘生丁试验(DPT)心电图多变量分析,用104例建立的判别方程在17例进行前瞻性验证。回顾性判别结果,与单纯DPT后的S-T标准及联合心电图和症状学标准相比,敏感性分别提高34.4%(从52.5%到86.9%,P<0.01)和24.6%(从63.2%到86.9%,P<0.01),准确性分别提高18.3%(从72.1%到90.4%,P<0.01)和12.5%(从77.9%到90.4%,P<0.05),特异性无改变;前瞻性验证的诊断符合率为88.2%。
To evaluate the diagnostic value of dipyridamole stress test(DPT)based on multivariate analysis for coronary heart disease(CHD),121 consecutive subjects underwent a DPT conventional 12-lead electrocardiography(ECG).The discriminant function derived from the logistic analysis of 104 cases including 43 controls and 61 patients with CHD was verified in another 17 eases.The retrospective results showed that the discriminant function,as compared with conventional S-T criteria,combined S-T and DPT-induced angina pectoris criteria,increases the sensitivitv of test by 34.4%(from 52.5% to 86.9% P<0.01)and 24.6%(from 62.3% to 86.9% P<0.01)respectively,the accuracy 18.3%(from 72.1% to 90.4%,P<0.01)and 12.5%(from 77.9% to 90.4%,P<0.05)respectively.No change in specificity was noted,and the prospective study in 17 cases showed the coincidence rate with the discriminant function was 88.2%.
