目的:探讨心电图运动试验(TET)对诊断围绝经期女性冠心病(CAD)的预测价值。方法:拟诊CAD围绝经期女性患者236例先后行TET及冠状动脉造影(CAG),以CAG结果为金标准,分别计算TET诊断围绝经期女性CAD灵敏度、特异度、假阳性率及假阴性率。结果:围绝经期患者CAD发生率为13.14%;围绝经期女性CAD患者有高血压病、糖尿病、以及≥2个主要的CAD危险因素的发生率明显高于非CAD患者;围绝经期患者胸痛多为不典型心绞痛;TET诊断CAD的敏感性为70.45%,特异性为64.06%,阳性预测值31.0%,阴性预测值90.44%,假阳性率为35.93%,假阴性率为29.55%,正确率为65.25%。结论:TET阳性对围绝经期女性可疑CAD患者有一定的预测价值,不能轻易排除CAD诊断,应进一步行CAG以明确诊断;而TET阴性,则绝大部分可以排除CAD。
Objective: To investigate the predictive value of electrocardiogram exercise test (TET) in the diagnosis of perimenopausal women with coronary heart disease (CAD). Methods: TET and coronary angiography (CAG) were performed in 236 cases of CAD patients. The sensitivity, specificity, false positive rate and false negative rate of TET for perimenopausal women were calculated respectively based on the CAG results rate. Results: The incidence of CAD in perimenopausal women was 13.14%. The incidence of hypertension, diabetes mellitus and ≥2 major CAD risk factors in perimenopausal women with CAD was significantly higher than that in non-CAD patients. The incidence of chest pain Mostly atypical angina pectoris; TET diagnosis of CAD sensitivity was 70.45%, specificity was 64.06%, positive predictive value of 31.0%, negative predictive value of 90.44%, false positive rate was 35.93%, false negative rate was 29.55%, the correct rate Is 65.25%. Conclusion: TET positivity has some predictive value for suspected CAD patients of perimenopausal women. It can not be easily ruled out for CAD diagnosis. CAG should be used for further diagnosis. TET negative for the most part can exclude CAD.
