Abstract

Objective. To examine the comparative effects of biologic disease-modifying antirheumatic drugs (bDMARD) and tofacitinib against conventional synthetic DMARD (csDMARD) on incident cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA). Methods. RA patients with ≥ 1 year of participation in the FORWARD study, from 1998 through 2017, were assessed for incident composite CVD events (myocardial infarction, stroke, heart failure, and CVD-related death validated from hospital/death records). DMARD were categorized into 7 mutually exclusive groups: (1) csDMARD-referent; (2) tumor necrosis factor-a inhibitor (TNFi); (3) abatacept (ABA); (4) rituximab; (5) tocilizumab; (6) anakinra; and (7) tofacitinib. Glucocorticoids (GC) were assessed using a weighted cumulative exposure model, which combines information about duration, intensity, and timing of exposure into a summary measure by using the weighted sum of past oral doses (prednisolone equivalent). Cox proportional hazard models were used to adjust for confounders. Results. During median (IQR) 4.0 (1.7-8.0) years of follow-up, 1801 CVD events were identified in 18,754 RA patients. The adjusted model showed CVD risk reduction with TNFi (HR 0.81, 95% CI 0.71-0.93) and ABA (HR 0.50, 95% CI 0.30-0.83) compared to csDMARD. While higher GC exposure as weighted cumulative exposure was associated with increased CVD risk (HR 1.15, 95% CI 1.11-1.19), methotrexate (MTX) use was associated with CVD risk reduction [use vs nonuse HR 0.82, 95% CI 0.74-0.90, and high dose (> 15 mg/week) vs low dose (≤ 15 mg/week) HR 0.83, 95% CI 0.70-0.99]. Conclusion. ABA and TNFi were associated with decreased risk of CVD compared to csDMARD. Minimizing GC use and optimizing MTX dose may improve cardiovascular outcomes in patients with RA.
