平板运动试验与冠状动脉造影诊断冠心病的对照研究

Research about comparing the TET results with coronary angiography in the diagnosis of CAG

目的:分析平板运动试验(TET)与冠状动脉造影(CAG)的结果,探讨TET对冠心病的诊断价值。方法:选择396例有胸闷、胸痛的患者,进行TET和CAG,对比其结果,分析TET的敏感性和特异性。结果:396例患者中,TET阳性192例,其中CAG阳性158例,CAG阴性34例。TET阴性204例,其中CAG阴性156例,阳性48例。即TET的敏感性为76.7%,特异性为82.1%,预测准确性为81.35%,假阳性率为17.9%,假阴性率为23.3%。双支、3支冠状动脉病变的TET敏感性为81%和95%均明显高于单支病变的63.5%。女性TET假阳性率高于男性(P<0.05)。结论:TET诊断冠心病的敏感度和特异性较高,并可估测冠状动脉病变程度,且操作简单,是目前诊断冠心病较理想的非创性检查方法,适合临床广泛应用。

Objective：By compareing the treadmill exercise test（TET）results with coronary angiography （CAG）,to investigate clinical significance of TET in the diagnosis of coronary heart disease.Method：396patients with chest pain were involved,underwent TET and CAG,respectively,the diagnostic results were compared to get the sensitivity and specificity by statistical analysis.Result：Of 396patients,the positive number of TET is 192,of which.Positive number of CAG is 158,the negative is 34,The negative number of TET is 204,of which, the positive of CAG is 48,the negative is 156.The sensitivity,specificity,predicted sensitivty,false positive and false negative in the diagnosis of TET were 76.7%（158/206）,82.1（156/190）,81.35%,17.9（34/190）,and 23.3（48/206）.The sensitivity of TET in double and triple vessel diseese is higher than 63.5%in single vessel disease.The false positive rate in female was higher than that in male（P0.05）.Conclusion：It had high sensitirity and specificity in diagnosis of covonary disease,and could assess severity of coronary artery lumen stenosis, with simple operation,is noninvasived method in the diagnosis of CAG which is apposite to the widespread use in clinic.
