<h3>Background:</h3> Rheumatoid Arthritis (RA) is a chronic inflammatory autoimmune disease associated with an increased risk of cardiovascular events (1, 2). RA can be compared to type 2 diabetes mellitus as a cardiovascular (CV) risk factor (3). This study investigates the relationship between RA and subclinical atherosclerosis, focusing on Carotid Intima-Media Thickness (CIMT) and carotid stenosis within the Paracelsus 10000 cohort (4) <h3>Objectives:</h3> Investigating the relationship between Rheumatoid Arthritis (RA) and subclinical atherosclerosis, specifically focusing on Carotid Intima-Media Thickness (CIMT) and carotid stenosis. Analyzing real-world data from the Paracelsus 10000 cohort to assess the association between RA and cardiovascular risk. <h3>Methods:</h3> Real-world data from the Paracelsus 10000 cohort were analyzed to assess the association between RA and cardiovascular risk. Logistic regression models were employed to evaluate the odds of any carotid stenosis in Common Carotid Artery (CCA) and Internal Carotid Artery (ICA) in RA patients. Stenosis was defined as any classification score above 0 according to the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Linear regression was used to analyze CIMT, adjusting for traditional cardiovascular risk factors (SCORE2) (5). Additionally, we calculated the relative risk (RR) using Stata's adjrr command. <h3>Results:</h3> Among 9,831 individuals, RA was associated with a statistically significant increase in CIMT by 0.03 millimeters compared to non-RA individuals (p = 0.004). RA was associated with a significantly higher risk of carotid stenosis (odds ratio [OR] = 1.43, 95% CI = 1.12 to 1.82, p = 0.004). After adjusting for potential confounders, including SCORE 2, the association remained significant (OR = 1.34, 95% CI = 1.01 - 1.78 p = 0.046). The relative risks (RR) show that RA individuals having a 43% higher risk of carotid stenosis compared to non-RA individuals, which persisted even after adjustment for confounders (RR = 34%). <h3>Conclusion:</h3> This investigation highlights the role of rheumatoid arthritis (RA) as a potential contributor to subclinical atherosclerosis. While the statistical difference in CIMT is noteworthy, its clinical impact might be limited. The use of real-world data in this study enhances our comprehension of RA's influence on cardiovascular health. The findings highlight the importance of early cardiovascular risk assessment and management in RA patients. Our results suggest that, similar to diabetic patients who undergo routine carotid stenosis screening due to their increased risk, RA patients may also benefit from regular screening for carotid stenosis (6). <h3>REFERENCES:</h3> [1] Conrad N, Verbeke G, Molenberghs G, Goetschalckx L, Callender T, Cambridge G, et al.
