Sex Differences in Cardiovascular Risk Profiles of Patients with Rheumatoid Arthritis: Results from an Italian Multicentre Cohort

Abstract

Objective: The effect of sex and gender-related variables on the evaluation of cardiovascular (CV) risk in rheumatoid arthritis patients has been poorly explored. We investigated the differences in CV risk features and scores according to sex in a wide rheumatoid arthritis (RA) cohort. Methods: This is a cross-sectional analysis of a consecutive RA cohort. Disease-specific clinical and serologic variables, traditional CV risk factors and the 10-year CV risk calculated by the SCORE-2, Progetto CUORE and Expanded Risk Score-RA algorithms were compared in males and females. Results: A total of 820 patients (193 men, 627 women) were included. Disease activity was similar between the two sexes. A significantly higher prevalence of traditional CV risk factors and higher mean CV risk scores were detected in male compared to female patients. In the multiple linear regression analysis, a higher HAQ, csDMARD use and ACPA positivity were significantly associated with an increased CV risk in females, while b/tsDMARDs was associated with a lower CV risk in males according to different algorithms. Conclusions: The distribution of traditional CV risk factors and the 10-year risk of CV disease significantly differed in female and male patients despite similar disease activity. Disease-specific variables may contribute differently to CV risk according to sex. The CV screening in RA should also take into account the different distribution of CV risk factors between sexes.
