摘　　要：目的探讨平板运动试验可疑阳性对冠状动脉粥样硬化病变诊断的准确性。方法对71例平板运动试验可疑阳性的患者同期进行64排螺旋CT冠状动脉成像检查,采用校正χ2检验进行检查结果差异的比较。结果 71例平板运动试验可疑阳性患者中,经64排螺旋CT冠状动脉成像检查提示有冠状动脉病变者62例(87.3%),包括双支病变21例,三支病变18人,单支病变23人;呈阴性者9人(12.7%)。两种检测方法的结果差异有统计学意义(校正χ2=7.592 3,P=0.005 9)。结论平板运动试验对提示冠状动脉粥样硬化病变具较高的敏感性及特异性,但是此项检查受到年龄、性别、运动量及基础病等多种原因的影响,易出现可疑阳性,应综合临床情况评价其结果。Objective To evaluate the accuracy of treadmill exercise test （TET） probable positive suggesting coronary atherosclerosis. Methods Seventy one patients with TET probable positive were picked and given 64-slice spiral CT coronary angiography simultaneously. Correction Chiquare test was used to identify the difference between the two tests. Resuits Among the 71 patients with TET probable positive, the result of 64-slice spiral CT coronary angiography suggested 62 cases （87.3%）with coronary atherosclerosis, 21 cases with double vessels lesion, 18 cases with triple vessels lesion and 23 cases with single vessel lesion, while 9 cases （12.7%） were negative. There was a significant statistical difference between the results of the two tests （X^2=7.592 3 ,P = 0.005 9）. Conclusion TET is sensitivity and specificity on diagnosing coronary atherosclerosis. While the result of this test is often probable positive because of influencing of some factor such as age, gender, amount of exercise and basic diseases. So the results should be evaluated according to clinical situations.
