平板运动试验与冠状动脉造影的临床对比研究

Comparative study of treadmill exercise test and coronary angiography

目的:探讨平板运动试验在冠心病中的诊断价值。方法:比较分析行平板运动试验及冠状动脉造影检查的189例患者的检查结果。以冠状动脉造影结果为标准,统计分析平板运动试验的敏感性、特异性。结果:患者平板运动试验检出冠心病的敏感性为71.5%,特异性69.1%,阳性预测值70.1%,阴性预测值70.6%。TET诊断冠脉多支病变的敏感性高于单支病变患者,两者比较差异有统计学意义(P<0.05)。性别对平板运动试验差异无统计学意义(P>0.05)。冠心病高危人群中平板运动试验阳性率较高(P<0.05)。结论:平板运动试验操作简单、安全无创,对冠心病的诊断具有较高的敏感性和特异性,可广泛应用于临床筛查和辅助诊断冠心病。

Objective： To investigate the value of treadmill test （TET） in the diagnosis of coronary heart disease. Methods： 189 patients with pseudo-coronary heart disease were collected which were examined by TET and coronary angiography （CAG）. The result of CAG was defined as the diagnostic criteria, the sensitivity and specifity of TET was analyzed. Results： The sensitivity, specificity, positive forecast value and negative forecast value of TET were 71. 5%, 69. 1%, 70.1% , 70.6% respectively. The sensitivity of TET in the patients with two or more vessel disease were higher than single vessel disease （P 〈 0.05）. Gender difference had no significant effect on TET （P 〉 0.05 ）. There was a higher sensitivity of TET in patients at high risk for coronary artery disease （ P 〈 0.05 ） diagnosis of coronary Conclusion ： TET is a simple and non-invasive methods for the screening and heart disease.
