Abstract:Objective To research clinical application of dual-source coronary CT angiography (CTA) in the diagnosis of different grades of coronary stenosis in type 2 diabetes mellitus (T2DM) patients with coronary heart disease (CHD). Methods From April 2017 to April 2020, 96 patients with T2DM and CHD in General Hospital of Huainan Eastern Hospital Group were selected as the research objects. The result of dual-source coronary CTA and CAG in the diagnosis of different grades of coronary stenosis in patients with T2DM and CHD were compared, and the diagnostic efficiency of dual-source coronary CTA in the diagnosis of different grades of coronary stenosis in patients with T2DM and CHD were analyzed. Results There was no significant difference in between the two methods in the different grades of coronary stenosis (P > 0.05). The AUC of dual-source coronary CTA in the diagnosis of slight, mild, moderate and severe coronary stenosis were 0.823, 0.801, 0.794, 0.928; and the sensitivity were 80.00%, 77.78%, 83.33%, 95.24%, respectively; and the specificity were 99.37%, 98.41%, 98.37% and 99.38%, respectively. Conclusion Dual-source coronary CTA can accurately grade the degree of coronary stenosis in patients with T2DM and CHD. It has high diagnostic efficiency and is a safe, efficient and non-invasive examination method.
