Coronary computed tomographic angiography (CCTA) provides information on coronary atheroscle-rosis burden and extent. In the present analysis, we compared the prognostic impact of coronary scores (maximal coronary stenosis, segment involvement score SIS and segment stenosis scores SSS, and the CCTA-modified Duke score).Patients and methods. We retrospectively reviewed CCTA images of patients with suspected coronary obstruc-tion and excluded patients who underwent planned revascularization. Using Cox multivariate analysis, we estimated the hazard ratio (HR) with 95% confidence intervals (CI) for different coronary scores to predict death, myocardial infarction, and late unplanned revascularizations (as individual and composite endpoints). Model performance was evaluated using area under time-dependent receiver operating characteristic curves (AUC).Results. We included 750 patients (median age 61 years, 54% women) with a median follow up 1,465 days. Unadjusted HR for major cardiovascular events ranged from 3.87 (95% CI 1.49-10.0, p = 0.005) for obstructive disease (> 50% stenosis in any vessel) to 1.17 (1.09-1.25, p < 0.001) for SIS (each additional segment involved). Predictions re-mained significant for all endpoints and after adjusting for coronary artery calcium score and risk factors. Area under curve (AUC) for coronary stenosis was 0.77 (95% CI 0.71-0.82), for SIS was 0.77 (95% CI 0.72-0.83), for SSS was 0.77 (95% CI 0.71-0.82), and for Duke score was 0.67 (95% CI 0.61-0.74).Conclusions. Our study has confirmed that coronary atherosclerosis burden and extent independently predict major cardiovascular events in patients who had undergone CCTA, but were not referred for invasive diagnostic procedures and revascularizationTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo radiologije in onkologije
