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

A comparison study between the transthoracic echocardiography, electrocardiography, and multi slice spiral CT coronary angiography in diagnosis of coronary heart disease

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。

Objective To compare the value of transthoracic echocardiography （TTE）, electrocardiography （ECG）, and Multi slice spiral CT coronary angiography （ MSSCTCA）in diagnosis of coronary heart disease （ CHD ）. Methods The findings of TTE, ECG, and MSSCTCA were retrospectively analyzed in 207 cases diagnosed as CHD, and the results were compared with those of coronary angiography （CAG）. The sensitivity and specificity of each method were compared. Results Among the 207 cases, 165 cases of CHD were confirmed by CAG. TTE showed regional wall motion abnormality in 139 cases, ECG showed ST-T changes in 115 cases, and MSSCTCA showed abnormal imaging in 149 cases. The sensitivity and specificity of TTE and ECG, MSSCTCA in diagnosis of CHD were 79.39 %, 59.39 %, 87.89 % and 80.95 %, 59.52 %, 90.48 % respectively. Conclusion The sensitivity and specificity of MSSCTCA are higher than TTE and ECG. It has higher accuracy in the diagnosis of CHD, indicating that this method has great potential in future clinical applications.
