摘要
目的:通过回顾性分析静息心电图正常的冠心病患者平板运动试验结果及冠脉病变特征,以减少对冠心病的漏诊率。方法:对我院心血管内科2005年1月至2009年1月期间住院的静息心电图正常但确诊为冠心病的30例患者进行平板运动试验及冠脉造影结果的对比分析。结果:30例静息心电图正常的冠心病患者,其平板运动试验阳性者18例(60.0%),可疑者2例(6.7%);该30例患者的冠脉造影结果显示:单支血管病变16例(53.3%),双支血管病变10例(33.3%),三支血管病变4例(13.3%),有侧支循环形成者8例(26.7%)。结论:冠脉明显狭窄者可表现为静息心电图正常,与冠脉病变程度轻、侧支循环建立及多支血管病变中与血管狭窄部位相互对应有关;平板运动试验假阴性与冠脉单支病变、心肌缺血范围小、侧支循环建立良好、运动量不足等因素相关。
Objective： To evaluate the value of treadmill exercise test （TET） for diagnosing coronary artery disease （CAD） by comparative analysis of treadmill exercise test and coronary angiography. Methods： 30 normal resting electrocardiogram patients with coronary artery disease, hospitalized in the Department of Cardiovascular of the Affiliated Hospital of Yan＇an University from Jan. 2005 to Jan. 2009, the result of their treadmill exercise test （TET） and the data of coronary angiography were comparatively analyzed. Results： 18 of these had true positive exercise testing results, accounting for 60.0% and 2 cases had suspicious results （6. 7%）; significant CAD was detected by angiography in 30 patients, 16 eases were single-vessel disease （53.3%）, 10 cases were double-vessel disease （33.30%）, 4 cases were triple-vessel disease （13.3%）, 8 of these have formed the collateral circulation （26.7%）. Conclusion： Obvious coronary artery stenosis could show normal resting electrocardiogram, this normal resting electrocardiogram are related to slight pathological changes are coronary artery, the formation of collateral circulations and the opposite locations of lesions of more than one vessel; and the false negative result of treadmill exercise test has correlation to the following factors such as single vessel coronary artery disease, the small area of myocardial isehemia, a good collateral circulation formation and insufficient physical activity .
