摘　　要：目的了解已确诊冠心病患者的平板运动试验(TET)不同结果与冠脉CT病变特征之间的联系。方法选取118例经冠状动脉造影确诊为冠心病的患者为研究对象,按TET结果分为阴性组、可疑阳性组、阳性组,比较三组间冠脉造影结果及冠脉CT斑块病变特征。结果TET阳性者37例(31.4%),可疑阳性者39例(33.0%),阴性者42例(35.6%),冠心病TET假阴性率达35.6%; TET可疑阳性组与阳性组在冠状动脉病变数目、狭窄程度、病变血管发生率及冠脉CT斑块病变性质方面的差异无统计学意义(P>0.05);TET可疑阳性组冠脉CT非钙化斑块数目比例多于阴性组[21/13(P=0.031)]。结论对平板运动试验阴性和可疑阳性患者,不应轻易否认或排除冠心病诊断,而应结合临床情况进行综合分析。AIM To understand the relationship between the different results of treadmill exercise test（TET） and the pathological change characteristics of coronary artery CT image in already diagnosed coro- nary artery disease patients. Methods 118 coronary artery disease patients diagnosed by the coronary angi- ography were selected, divided into the negative group, the suspected positive group and the positive group according to the TET results, compared with the coronary artery CT pathological change characteristics. Results The rate of positive TET was 31.4% （37 cases）, the rate of suspected positive TET was 33.0% （39 cases）, and the rate of negative TET was 35.6% （42 eases）. The TET false negative rate reached 35.6%. The number of non-calcified lesions in TET suspected positive group was more than that in TET negative group [ 21/13 （P = 0.031 ） ] . Conclusion It must be careful to deny or exclude the diagnosis of coronary artery disease in those patients with negative or suspected positive TET results. The doctor should analyze the different clinical situations of the patients.
