20.500.12556/DiRROS-28915 Coronary computed tomographic angiography and atherosclerosis prognostic validation of coronary scores in a Slovenian cohort Background. 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 revascularization. atherosclerosis coronary computed tomographic angiography coronary scores ateroskleroza računalniška tomografska angiografija koronarnih arterij koronarna bolezen true false false Angleški jezik Slovenski jezik Neznano 2026-04-14 08:55:10 2026-04-14 08:55:10 2026-04-15 03:57:34 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 14. 4. 2026; str. 59-66 no. 1 Vol. 6 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.13-004.6 1581-3207 10.2478/raon-2026-0004 275084547 RAZ_Flerin_Poropat_Tadeja_2026.pdf RAZ_Flerin_Poropat_Tadeja_2026.pdf 1 BA1A12BF290B2026E8BBA476E02D2403 8505844a2bbf415a2d6cb955a19716822debcf5805b42a522cec4a22e7444547 fd05e336-37ce-11f1-9cc3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43125 https://reference-global.com/article/10.2478/raon-2026-0004 1 e3111e8c-37ce-11f1-9cc3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43124 Univerzitetni klinični center Ljubljana 0 0 0
