Linear regression was used to estimate regression coefficients for echocardiographic characteristics and logistic regression to estimate odds ratios (ORs) for carotid and femoral plaques, coronary artery calcium (CAC) scores, and coronary noncalcified plaques (NCPs).<\/jats:p><\/jats:sec>Results<\/jats:title>Of 164 participants, 80 (48.8%) were active AAS users (median age, 35 [IQR, 30-43] years; 61 men [76.2%]), 26 (15.9%) were previous users (median age, 36 [IQR, 28-51] years; 18 men [69.2%]), and 58 (35.4%) were nonusers (median age, 40 [IQR, 31-46] years; 42 men [72.4%]). Median cumulative lifetime AAS use was 2.2 (IQR, 1.2-7.2) years for active and 2.2 (IQR, 1.0-5.5) years for previous users. No group differences were observed when comparing the number of participants with femoral (active users, 15 [19.7%]; previous users, 5 [19.2%]; nonusers, 11 [20.8%]; P<\/jats:italic>\u2009=\u2009.89) or carotid (active users, 24 [31.2%]; previous users, 12 [46.2%]; nonusers, 13 [24.1%]; P<\/jats:italic>\u2009=\u2009.47) artery plaques or CAC scores (median score was 0 across all groups with range of 0-228 for active users, 0-800 for previous users, and 0-163 for nonusers; P<\/jats:italic>\u2009=\u2009.36), whereas a statistically significant difference in the prevalence of coronary NCPs was found between active users (19 [23.8%]) and nonusers (6 [10.3%]) (P<\/jats:italic>\u2009=\u2009.03). However, in confounder-adjusted logistic regression, longer cumulative lifetime AAS use was associated with higher odds of a positive CAC score (OR, 1.23; 95% CI, 1.09-1.39; P<\/jats:italic>\u2009=\u2009.001) and presence of coronary NCPs (OR, 1.17; 95% CI, 1.05-1.30; P<\/jats:italic>\u2009=\u2009.004). AAS use exceeding 5 years was associated with greater severity of calcifications (n\u2009=\u200994; \u03c72<\/jats:sup>\u2009=\u20099.78; P<\/jats:italic>\u2009=\u2009.04). Echocardiography showed that cumulative AAS use was associated with worse left ventricular (regression coefficient: 0.08; 95% CI, 0.03-0.12; P<\/jats:italic>\u2009=\u2009.002) and right ventricular (0.08; 95% CI, 0.03-0.13; P<\/jats:italic>\u2009=\u2009.001) global longitudinal strain.
