Abstract: PURPOSE: The aim of this study was to compare epicardial adipose tissue thickness (EATT), which is a novel cardiometabolic risk factor in patients with ankylosing spondylitis (AS), and carotid intima media thickness (CIMT) with healthy controls to assess the relationship between these markers and disease activity. MATERIALS AND METHODS: This study involved 38 patients with AS and 38 controls with no history of cardiovascular disease. CIMT was measured by Doppler ultrasound, and EATT by echocardiography, in all participants. Total cholesterol (TC), low density lipoprotein (LDL) cholesterol, high density lipoprotein cholesterol, triglycerides, thyroid stimulating hormone, erythrocyte sedimentation rate, C-reactive protein, and hemogram measurements were performed in all subjects after 8 hours of fasting. In addition, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI) scores of the patients with AS were recorded. RESULTS: EATT was significantly higher in patients with AS (0.45 ± 0.17 mm) compared with healthy (0.37 ± 0.10 mm) controls (p= 0.01). Significant positive correlations were detected between EAT thickness and BASFI, CIMT, and disease duration in patients with AS (p= 0.008, p= 0.024, and p= 0.012, respectively). Significant negative correlations were observed between EATT and TC and LDL cholesterol concentrations (p= 0.016 and p= 0.009, respectively). No significant difference was detected in CIMT between the patients (0.515 ± 0.08 mm) and the controls (0.517 ± 0.094 mm, p= 0.98). No significant correlation was observed between CIMT of the patients with AS and the BASDAI, BASFI, TC, HDL cholesterol, systolic blood pressure, or diastolic blood pressure values. Significant positive correlations were observed between CIMT and waist circumference, weight, body mass index, and LDL cholesterol in patients with AS and the controls. CONCLUSIONS: This study demonstrated increased EATT in patients with AS compared with a healthy population, which was positively correlated with disease duration and BASFI.
