Prognostic value of coronary CT angiography in diabetic patients: a 5-year follow up study
Abstract
Prevalence of coronary artery disease (CAD) is high in diabetic patients while diagnosis of early stage of CAD remains demanding. This study evaluates prognostic value of coronary computed tomography angiography (CCTA) for long-term outcome to predict cardiac events in oligosymptomatic diabetic patients. A cohort of 108 consecutive diabetic patients without angina pectoris or known CAD, undergoing CCTA was included. 1379 consecutive patients without diabetes were defined as a control group. Coronary artery calcium score (CACS), segment involvement score (SIS) and the segment stenosis score (SSS) were documented. The end point was a composite of cardiac events defined as all-cause death, nonfatal myocardial infarction, or unstable angina requiring hospitalization. Follow up period was 66.0 ± 14.2 month. 98% of initially enrolled patient were followed. During follow-up period 10 cardiac events within the diabetic cohort and 48 within the non-diabetic cohort were observed. Annual event rate in diabetic and non-diabetic patients was 1.74 and 0.64% respectively. In diabetic patients a multivariate analysis showed significant prognostic value over Framingham Score for SIS with a hazard ratio (HR) of 2.98 (95% CI 1.02, 8.72; p = 0.047) and SSS (HR 4.47, 95% CI 1.21, 16.49; p = 0.025), while CACS did not add prognostic value in this cohort. Annual event rate was 0% in diabetic patients with SIS = 0 and 3.9% in diabetic patients with SIS ≥ 8. CCTA allows for improved risk prediction f…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
