Epicardial Fat: A Hidden Cardiovascular Risk in Inflammatory Arthritis

Cardiovascular disease (CVD) remains the leading cause of death among individuals with inflammatory arthritis, such as rheumatoid arthritis (RA) and spondyloarthritis (SpA). Recent research has identified epicardial fat volume (EFV) as a novel marker for assessing cardiovascular risk in these patients. Understanding the implications of EFV can provide valuable insights into managing metabolic health, particularly for those with inflammatory conditions. In a study involving 242 patients, including 114 with RA, 28 with ankylosing spondylitis, and 100 with psoriatic arthritis, researchers measured EFV through coronary artery calcium scoring (CACS) via computed tomography. The results indicated that EFV was significantly higher in patients with SpA compared to those with RA (104.2 ± 46.7 ml vs. 86.7 ± 47.9 ml, p = 0.004). Furthermore, while high sensitivity C-reactive protein (hsCRP) showed a positive correlation with elevated EFV (β adjusted for Framingham risk score 0.97, 95% CI 0.39-1.56), no direct association was found between EFV and individual clinical disease activity indices. The findings underscore the importance of monitoring EFV as a potential indicator of cardiovascular risk in patients with inflammatory arthritis. For individuals with SpA, the elevated EFV suggests a heightened risk of cardiovascular events, necessitating proactive health management strategies. Regular cardiovascular assessments, lifestyle modifications, and possibly pharmacological interventions may be warranted to mitigate these risks. This research connects closely with several biomarkers relevant to metabolic health, particularly hsCRP, which is an inflammation marker, and CACS, which reflects atherosclerotic burden. Monitoring these biomarkers can help individuals understand their cardiovascular risk better and take appropriate actions. In conclusion, the study highlights the critical role of epicardial fat as a cardiovascular risk factor in inflammatory arthritis. Patients and healthcare providers should prioritize cardiovascular health assessments and consider integrating lifestyle changes aimed at reducing inflammation and improving overall metabolic health.
