Background: Aortic stiffness is an independent predictor of cardiovascular events which is increased in rheumatoid arthritis (RA). It can be measured by carotid-femoral pulse wave velocity (cfPWV). Phase angle (PhA) is lower in patients with cardiovascular disease and may be informative in assessing the clinical course of RA. Materials and Methods: In this observational and cross-sectional study, all RA patients referred to the Imam Khomeini Hospital rheumatology clinic between September 2022 and March 2023 were included in the study. RA activity was assessed using the DAS28 criteria. In the patients, PhA and cfPWV were measured using Inbody-s10 and PulsePen tonometer instruments. The relationships between PhA, cfPWV, clinical course of RA, and CRP were evaluated using regression analysis. Results: 53 patients were included in the study (83% female, mean age 46.5 years). Significant inverse relationships existed between PhA, CRP, and age (P value = 0.003, 0.0001, R: 0.69, respectively). People with aortic stiffness had a lower mean PhA (P value = 0.05). In patients with RA duration of less than 10 years, the cfPWV percentile and the prevalence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) positive cases were higher than in patients with RA duration >10 years (P values = 0.02, 0.01, respectively). Conclusions: With increasing duration of RA, aortic stiffness and positive serology cases decreased. PhA and cfPWV may be useful in assessing the clinical course of RA to prevent cardiovascular events.
