目的：将冠状动脉造影与运动平板试验作对比，探讨运动平板试验在冠状动脉粥样硬化性心脏病诊断中的临床意义。方法：选择临床上疑诊为冠状动脉粥样硬化性心脏病的患者125例，每一例患者在行冠脉造影前都要进行运动平板试验，以冠脉造影为检测标准，将运动平板试验与冠脉造影检查结果作比较。结果：运动平板试验检出冠心病的敏感性为83.3%，特异性为80.3%，预测准确性81.6%。单支、双支、三支病变阳性率为76.0%、84.2%和100.0%，三者比较差异有统计学意义（P ﹤0.05）。结论：在冠状动脉粥样硬化性心脏病患者检查方法中，运动平板试验是一项比较理想的无创伤性且简单的检查方法，在冠心病的诊断中具有重要的临床价值。%Objective:To investigate the clinical significance of treadmill exercise test in the diagnosis of coronary athero-sclerotic heart disease by comparing the coronary angiography with treadmill exercise test. Methods:125 cases of clinical-ly suspected coronary heart disease patients were selected,and each patient had to undergo exercise treadmill test before coronary angiography. Then the results of treadmill exercise test and coronary angiography were compared by taking the coronary angiography as the testing standard. Results:The susceptibility of treadmill exercise test for coronary heart dis-ease was 83. 3% ,the specificity was 80. 3% ,the predictive accuracy was 81. 6% . Single,double,three lesions in the positive rate was 76% ,84. 2% and 100% ,there was statistically significant difference between the three. Conclusions:Treadmill exercise test is an ideal noninvasive and simple inspection method,and it has important clinical value in the di-agnosis of coronary heart disease.
