A Study of Assessment of Preclinical Atherosclerosis by Carotid Intima-media Thickness in Newly Diagnosed Patients with Rheumatoid Arthritis Younger than 50 Years of Age and Their Correlation with Disease Activity: A Comparative, Cross-sectional Study

Abstract

Abstract Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune condition that has been linked to an increased risk of atherosclerosis and enhanced cardiovascular disease (CVD) risk. Most literature encompasses older age groups. Objectives: This study aimed to determine the carotid intima-media thickness (CIMT) in patients with newly diagnosed RA who are younger than 50 years of age and do not display the symptoms or traditional risk factors of CVD and compare it to the controls with same age and gender without RA. Furthermore, the correlation between CIMT and the disease activity Score -28 (Erythrocyte sedimentation rate) were examined. Subjects and Methods: The study enrolled 48 patients with RA and 51 healthy controls who met the study’s inclusion and exclusion criteria. All patients underwent CIMT by the ultrasound. Results: There was a significant increase in common carotid artery CIMT on both the right and left sides (P < 0.001) in RA patients as compared to controls. The correlations between CIMT (right and left) and DAS 28 ESR were only poor and negative. Conclusion: Younger patients with RA showed higher CIMT than age- and sex-matched controls, indicating an increased risk of future cardiovascular events even in the young.
