Zusammenfassung:Abstract Background Development of coronary artery disease (CAD) and risk of acute cardiac events differ between women and men during the life span. The aim of this study was therefore to characterize sex differences in coronary artery plaque phenotype among patients with symptomatic non-obstructive CAD in different age groups. Methods Advanced coronary artery plaque phenotyping by coronary computed tomography angiography was performed in 606 patients (31% women) with symptomatic non-obstructive CAD from the Norwegian Registry of Invasive Cardiology. A 1:1 sex-matched study design ensured equal distribution of the sexes in the different age groups. We assessed total plaque burden adjusted for vessel volume and plaque composition consisting of dense calcium, fibrous, fibro-fatty, and necrotic core. Patients were further stratified into age groups of ≤50, 51-64, and ≥65 years to explore the relationship between age and sex on coronary artery plaque phenotype. Results In the study population, patients ≥65 years had a higher prevalence of hypertension, higher calcium score, coronary artery segment involvement score and total plaque burden, whereas the prevalence of obesity was lower compared to patients aged 51-64 and ≤50 years (all p
