Meta-analysis of risk factors for cardiovascular disease in patients with rheumatoid arthritis.

BACKGROUND

Cardiovascular disease (CVD) is a common complication of rheumatoid arthritis (RA). We aimed to explore the risk factors for cardiovascular disease in patients with rheumatoid arthritis and provide a scientific basis on effective prevention and treatments for CVD in RA patients.

METHODS

We searched for a combination of the subject words and free words involved arthritis, rheumatoid, CVD, heart disease, vascular disease, risk factors, etc. from China Knowledge Network, Wanfang, Vip, China Biomedical Literature Database, Pubmed, Embase, Web of Science, Cochrane and other databases for documents published in public in 2000-October 2022.RevMan 5.3 and Stata14.0 analysis software was used to perform a meta-analysis of case-control and cohort studies on risk factors of CVDs in patients with RA published from 2000 to 2022.The Egger method was used to determine whether there was publication bias.

RESULTS

Seventeen pieces of literature were included in this meta-analysis. We explored the associations between CVD and different clinical characters such as DAS28 score, rheumatoid factor, triglyceride, age, sex, C-reactive protein, total cholesterol (TC), hypertension, and D dimer. High serum levels of C-reactive protein, TC, and D-dimer, as well as hypertension, are the main risk factors for CVD in patients with RA. The OR and 95% CI of C-reactive protein were 2.06 (1.91-2.23), RR and 95% CI of TC were 1.7 (1.49-1.93), RR and 95% CI of hypertension were 3.58 (2.37-5.40), as well as OR and 95% CI of D dimer were 2.83 (1.48-5.40).Our results performed by the meta-analysis were reliable, with low publication bias existed.

CONCLUSION

C-reactive protein, TC, hypertension, and D dimer are the main risk factors for CVD in patients with RA. No protective factors were found.
