Background: Patients with rheumatoid arthritis are at increased risk of developing cardiovascular disease. In Mongolia, the registration of inflammatory diseases is increasing every year, and cardiovascular diseases are the leading cause of death. Aim: We aimed to determine the degree of cardiovascular risk and its correlation in people with rheumatoid arthritis. Materials and Methods: The study was conducted in a cross-sectional study design with 64 patients with rheumatoid arthritis between May and November 2024. Cardiovascular risk was assessed using mSCORE and the World Health Organization (WHO) cardiovascular Risk Table. We received ethical approval to begin the research at the MNUMS meeting on May 17, 2024 (No. 2024/3-05). Results: The average age of the participants was 55.2±9.7 years, and the average duration since being diagnosed with RA was 9.8±8.0 years. Among the participants, 82.8% (n=53) were female, and 17.2% (n=11) were male. The mean WHO risk index was 10.25±11, while the mean mSCORE risk index was 2.9±4 (p=0.001). There was a significant difference in mSCORE scores between the 40-55 and 56-65 age groups (p<0.001). In contrast, the mSCORE risk assessment showed that 15.6% (n=10) had high risk, and 6.3% (n=4) had very high risk. Among the parameters of inflammatory biomarkers, CRP (OR=0.05, r=0.35, 95% CI 0.9-3.2, p=0.004) has a statistically significant difference and positive correlation, and HDL-C (OR=2.3, r=-0.25, 95% CI 2.9- 10.0, p<0.0001) was significantly different and negatively correlated. Conclusion A total of 64 participants participated in our study, and according to the WHO assessment, 17.2% were at high or very high risk of developing cardiovascular disease in the next 10 years, and according to the mSCORE, 21.9% were at high or very high risk of developing cardiovascular disease. Although the degree of disease activity was not significantly associated with cardiovascular risk, the inflammatory biomarker C-reactive protein was statistically significantly different or positively associated with cardiovascular risk assessment.
