Factors associated with secondary coronary artery disease in rheumatoid arthritis patients: A systematic review and meta-analysis based on observational studies.

Abstract

The main objective of this systematic review was to investigate the factors influencing the development of coronary artery disease (CAD) in patients with rheumatoid arthritis (RA). PubMed, Embase, Web of Science, Wan Fang Date, CBM, CNKI, and VIP databases were systematically searched to select the relevant literature. The quality of the incorporated studies was assessed with reference to the Newcastle-Ottawa Scale. Stata16 was adopted to summarise the odds ratios, risk ratios, hazard ratios, and 95% confidence intervals for meta-analysis. A total of 29 studies were included in this analysis, wherein the average age of RA patients was 50.5-81years and the proportion of women was 44.4%-92%. The present meta-analysis suggested that increased CAD risk in RA patients was associated with age, male gender, smoking, glucocorticoids, Health Assessment Questionnaire scores, hyperlipidaemia, hypertension, diabetes, and C-reactive protein concentration. The present systematic review revealed the influencing factors of secondary CAD in RA patients, some of which could reduce the risk of secondary CAD through effective interventions, such as smoking cessation, exercise, and medications. However, the effects of age, RA severity, and different medication subgroups on CAD risk stratification warrant further investigation.
