平板运动试验与冠状动脉造影的对比研究

目的:探讨平板运动试验(TET)与冠脉造影的结果,评价无创TET在冠心病诊断中的价值。方法:比较分析行平板运动试验及冠脉造影检查的93例患者的检查结果。结果:通过与冠状动脉造影(CAG)的对比,分析TET检出冠心病的灵敏性为87.5%,特异性为44.8%,准确度为77.4%,并分析患者病变程度、年龄、性别对TET结果的影响。结论:TET具有安全、无创、价廉、操作简单等优点,有较高的敏感性和特异性,与冠状动脉造影结合起来可以提高冠心病诊断的准确性,其价值较静息心电图高。

Contrast study of treadmill exercise testing and coronary angiography

Objective Through contrasting the results of treadmill exercise testing（TET） and coronary angiography（CAG）,to evaluate the value of TET in the diagnosis of coronary heart disease.Method The test results of TET and CAG in 93 patients were comparative analyzed.Results Compared with CAG,the sensitivity of TET in diagnosing of coronary heart disease was 87.5%,the specificity was 44.8%,the accuracy was 77.4%,and the effects of the degree of pathological changes,age and sex on TET were analyzed.Conclusion TET has the advantages of security,non-invasion,cheap and simple operation etc,has high sensitivity and specificity,and can improve the diagnostic accuracy of coronary heart disease together with coronary angiography,its value is higher than resting electrocardiogram.
