162 Coronary artery calcification on non-gated, non-cardiac ct has prognostic and treatment implications regardless of age

IntroductionCoronary artery disease (CAD) is a progressive, inflammatory disorder with calcification forming as plaque heals. Coronary artery calcification (CAC) is thus a biomarker of CAD. The 2020 BSCI/BSTI guidelines recommended, for the first time, reporting CAC on all thoracic CT regardless of the indication and acquisition modality. However, its routine reporting is infrequent and the clinical relevance of this in all age groups has been debated. This study assessed CAC prevalence, prognosis and the potential impact of its reporting on management in unselected patients undergoing routine non-cardiac thoracic CT.MethodsA retrospective analysis of 1400 consecutive non-cardiac chest CT imaging performed in our institution from 1st January 2015 was performed until 200 individual patient scans in each age group (
