运动平板Duke评分诊断冠心病的价值

The value of Duke treadmill score in coronary heart disease

目的 探讨运动试验中Duke评分对冠心病的诊断价值.方法 对94例行冠状动脉造影患者行运动试验,并计算出Duke评分,分析Duke评分与冠状动脉造影间的相关性.结果 Duke评分对男性及女性冠心病诊断的准确性、阳性预测值分别为：88.9％、85.0％;89.6％、82.5％,与传统的心电图ST段改变的标准相比,差异有统计学意义（x2 =4.27,P＜0.05）.结论 Duke对冠心病的诊断,在准确性、阳性预测值等方面要明显优于心电图ST段压低标准.

Objective To discuss the value of Duke treadmill score in the diagnosis of coronary heart disease.Methods 94 inpatients underwent treadmill test and coronary angiography,the relationship between the Duke treadmill score and the results of coronary angiography was analyzed.Results The prognostic accuracy and positive predictive value of Duke treadmill score to male and female were 88.9%,85.0% ;those of traditional electrocardiogram ST standard were 89.6%,82.5 %,the differences were significant （x2 =4.27,P 〈 0.05）.Conclusion The Duke treadmill score is much more significant than the traditional ST standard in the prognostic accuracy and positive predictive value of diagnosing coronary heart disease.
