活动平板心电图负荷试验与冠状动脉造影比较分析

Comparative Analysis between treadmill exercise test and coronary angiography

目的观察活动平板心电图负荷试验(Treadmill Exercise Test,TET)对冠状动脉粥样硬化性心脏病患者的诊断价值。方法将102例拟诊断为冠心病患者分别行平板试验和冠状动脉造影术检查,并对其结果进行比较分析。根据冠状动脉造影结果将患者分成冠心病组和非冠心病组,对各组活动平板试验结果进行分析。结果 102例患者中确诊为冠心病者81例,其中活动平板试验阳性68例(83.95%),阴性13例(16.05%)。非冠心病者21例,活动平板试验阳性6例(28.57%),阴性15例(71.43%)。本研究中活动平板试验诊断冠心病的敏感性为83.95%,特异性为71.43%。此外,TET对冠脉多支、左主干病变的检出率高于单支病变(P<0.05)。结论活动平板心电图负荷试验诊断冠心病敏感度和特异度均较高,对多支病变及左主干病变的检出率更高,是目前理想的非创伤性检查手段之一。

Objective Observation of the diagnosis value of Treadmill Exercise Test（TET） to coronary heart disease（CHD）. Methods 102 cases to be diagnosed with coronary heart disease were performed treadmill exercise test and coronary angiography examination,and the results were compared.According to the results of coronary angiography,patients were divided into CHD group and non-CHD group,treadmill exercise test in each group were analyzed.Results 102 patients diagnosed with coronary heart disease in 81 cases,including treadmill exercise test was positive in 68 cases（83.95%）,negative 13 cases（16.05%）.Non-coronary heart disease in 21 cases,treadmill exercise test was positive in 6 cases（28.57%） and negative in 15 cases（71.43%）.In this study,treadmill exercise test in diagnosis of coronary artery disease with a sensitivity of 83.95%,specificity of 71.43%.Conclusions TET has both higher sensitivity and higher specificity of detecting coronary artery disease,especially for multi-vessel disease and left main disease detection rate,can be the ideal means of non-invasive examination.
