Abstract:Objective To study the value of treadmill exercise test (TET) and coronary computed tomographic angiography (CCTA) in the diagnosis of coronary heart disease (CHD). Methods A total of 118 patients with suspected CHD in our hospital were selected as research subjects, and performed TET, CCTA and coronary angiography (CAG) within one month. The examination results of TET and CCTA were analyzed with CAG results as diagnostic gold standard. ResultsThe detection rate of severe stenosis lesions by TET is significantly higher than that of moderate stenosis lesions (P<0.05). The detection rate of single and multivessel lesions does not vary significantly (P>0.05). There is no significant difference in the detection rate of coronary artery stenosis degree, and single and multi-vessel lesions by using CCTA (P>0.05). The sensitivity and specificity of TET in the diagnosis of CHD are 81.3% and 81.4%, respectively while the rates of CCTA are separately 90.7% and 79.1%. The sensitivity and specificity of a combination of TET and CCTA are 96.0% and 72.1%, respectively. Conclusion Both TET and CCTA have high sensitivity and specificity in the diagnosis of CHD, which can be used as routine examinations among patients with suspected CHD. Combined examination helps to improve diagnostic sensitivity and avoid missed diagnosis.
