We retrospectively recruited patients with diabetes who were continuously admitted to the Department of Endocrinology at the Fourth Affiliated Hospital of Harbin Medical University from June 2020 to May 2022, including patients with previously diagnosed diabetes and those diagnosed during the current visit. A total of 337 patients underwent noncontrast chest CT and coronary CTA scans during this hospitalization for typical or atypical chest pain, and all had fasting blood samples taken for laboratory analysis within 24 h of admission. We excluded patients with previous coronary revascularisation (n = 28); previous cardiac diseases, including CAD (n = 45), myocardial infarction (n = 1) and pericarditis (n = 2); a history of tumours or active tumours (n = 5); type 1 diabetes mellitus (n = 1); contrast allergy (n = 4); poor image quality (n = 14); incomplete clinical information (n = 2); and coronary CTA with CT interval > 7 days (n = 6). Ultimately, 229 T2DM patients were included in this study, of whom 146 patients were diagnosed with CAD by invasive coronary angiography at this visit, including 109 patients with stable CAD and 37 patients with acute coronary syndrome; the remaining 83 patients did not develop CAD.
