摘　　要：目的 探究平板运动试验（TET）结合多层螺旋CT（MSCT）对冠心病的诊断价值.方法 选择临床拟诊冠心病（CAD）的患者200例,2周内先后进行平板运动试验、多层螺旋CT冠状动脉成像及冠状动脉造影（CAG）检查.以冠状动脉造影为＂金标准＂,分析平板运动试验、多层螺旋CT冠状动脉成像及两者结合对冠心病检出率的有关指标.结果 平板运动试验、多层螺旋CT冠脉成像及两者结合诊断冠心病的敏感性、特异性、阳性预测值、阴性预测值、准确性分别为81.3%（74/81）、70.6%（77/109）、69.8%（74/106）、81.9%（77/94）和75.5%（151/200）;83.5%（76/91）、84.4%（92/109）、82.6%（76/92）,85.2%（82/108）和84.0%（168/200）;98.0%（53/57）,100%（143/143）、100%（53/53）、97.3%（143/147）和98.0%（196/200）.结论 平板运动试验结合多层螺旋CT冠状动脉成像能明确诊断或排除冠心病.Objective To discuss the diagnosing value of treadmill exercise testing combined with coronary artery imaging with 16-detector row spiral CT for coronary heart diseases. Methods Two hundreds patients with suspected or diagnosed coronary artery diseases were studied using treadmill exercise testing, 16- detector row spiral CT, coronary angiography in two weeks. The results of them were compared and analyzed. Results The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of in diagnosis of CAD with the treadmill exercise testing, 16-detector row spiral CT and the combining of them were 1.3% （74/81）, 70.6% （77/109）, 69.8% （74/106）, 81.9% （77/94）, 75.5% （151/200） and 83.5% （76/91）, 84.4%（92/109）, 82.6%（76/92）, 85.2%（82/108）, 84.0%（168/200）and 98.0%（53/57）, 100%（143/143）, 100% （53/53）, 97.3% （143/147）, 98.0% （196/200） respectively. Conclusion The treadmill exercise testing combined with coronary artery imaging with 16-detector row spiral CT can diagnosis or exclude CAD.
