71例平板运动试验可疑阳性患者螺旋CT冠状动脉成像结果分析(1)
[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。

[Abstract] 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 Chi-square test was used to identify the difference between the two tests. Results 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 (χ2=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.

平板运动试验(Treadmill Exercise Test，TET)心电图是临床常用协助诊断冠心病的无创性检查方法之一，但其结果受很多因素的影响，易出现可疑阳性。多排螺旋CT冠状动脉成像可以显示冠状动脉斑块、冠状动脉狭窄部位及程度的情况，是对冠心病进行诊断的无创性检查方法之一。本文将对活动平板可疑阳性的患者同期行64排螺旋冠状动脉CT检查，并对两种检查结果进行对比分析，探讨活动平板可疑阳性对冠状动脉硬化病变诊断的准确性及其原因。

1.1 一般资料
选取本院2010年1月～2011年10月门诊及住院部经活动平板可疑阳性的患者71例，纳入标准为窦性心律同时一次屏气能达15 s以上。剔除碘过敏的患者，心率明显不规则的患者，包括心房颤动、频发早搏等，充血性心力衰竭Ⅲ～Ⅳ级、严重低血压(收缩压 <90 mm Hg)、严重高血压(>180/100 mm Hg)以及急性心肌梗死患者，严重肝肾功能不全或其他脏器严重功能不全者。本组71例患者中，男39例，女32例，年龄为(55.0±1.8)岁；71例患者中有劳力后典型胸痛患者14例，有自主神经功能紊乱者7例，其中合并高脂血症21例，糖尿病17例，高血压病20例。, http://www.100md.com(董宏伟 程红)
