经胸超声心动图、心电图、多层螺旋CT冠状动脉造影诊断冠心病的对比研究
Functional and Molecular Medical Imaging (Electronic Edition)(2015)
Abstract
目的:对比分析经胸超声心动图(TTE)、心电图(ECG)及多层螺旋CT冠状动脉造影(MSSCTCA)对冠心病的诊断价值。方法回顾分析207例冠心病患者的TTE、ECG及MSSCTCA检查结果,并与冠状动脉造影(CAG)检查结果做对照,分析比较各种检查方法的敏感性、准确性和特异性。结果207例中,CAG检查165例为冠心病,TTE显示139例节段性室壁运动异常,ECG显示115例ST-T段改变,MSSCTCA检查149例异常。TTE诊断冠心病的敏感性、准确性和特异性分别为79.39﹪、79.71﹪、80.95﹪;ECG诊断冠心病的敏感性、准确性和特异性分别为59.39﹪、59.42﹪、59.52﹪;MSSCTCA诊断冠心病的敏感性、准确性和特异性分别为87.89﹪、88.41﹪、90.48﹪。结论 MSSCTCA对冠心病诊断的敏感性、准确性和特异性均高于TTE和ECG,值得推广应用。
