三种无创检查法诊断冠心病的价值对比研究

目的用平板运动试验（TET）、多层螺旋CT三维成像（MSCT）、12导联动态心电图（12-AECG）Z种无创方法诊断冠心病进行比较，并以冠脉造影（ACG）为“金标准”，评价上述三种方法对冠心病的诊断价值。方法选择60例患者均进行，TET、MSCT、12-AECG和ACG检查。计算，TET、MSCT、12-AECG诊断冠心病的敏感性和特异性，并计算将上述三种方法两两联合、三种联合诊断冠心病的敏感性和特异性。结果以ACG结果为金标准，TET诊断心肌缺血的敏感性、特异性分别为79．07％和70．59％；12-AECG诊断心肌缺血的敏感性、特异性分别为72．09％和64．71％；MSCT诊断冠心病心肌缺血的敏感性、特异性和准确率分别为92．77％、91．08％和91．67％。MSCT与12-AECG联合、MSCT与TET联合及12-AECG与，TET联合使敏感性分别提高到95．35％、95．35％和97．67％。TET、12-AECG与，TET串联使特异性提高到100％。结论将三种无创方法联合可提高冠心病诊断的特异性。

Appreciation of three non-valnerarious detection in diagnosis of coronary artery disease

Objective To evaluate the diagnostic value of treadmill exercise test(TET),miltiple slice computed tomography(MSCT) and 12 lead ambulatory electrocardiogram(12-AECG)in detecting coronary artery disease(CAD). Methods 60 patients were enrolled,we performed coronary arteriongraphy(CAG),TET,MSCT and 12-AECG in all patients. According to the result of CAG,we computed the sensitivity and specificity of TET,MSCT and 12-AECG in detecting CAD respectively. Then we got the sensitivity and specificity by combinating M...
