RESUMO
OBJECTIVE: The aim of this systematic review and meta-analysis is to assess the effect of statin on major adverse cardiovascular events (MACE) and mortality in patients with RA. MATERIALS AND METHODS: A systematic literature search was performed using PubMed, Scopus, Embase, and Clinicaltrials.gov for studies investigating the effect of statin on MACE and mortality in RA patients up until 6 February 2022. The primary outcome was MACE, which can be defined as nonfatal myocardial infarction (MI), nonfatal presumed ischemic stroke, transient ischemic attack, any coronary or non-coronary revascularization, or cardiovascular death. The pooled effect estimated was reported as hazard ratio (HR). RESULTS: There were 40,307 patients from a total of six studies, comprising of one double-blind placebo controlled randomized controlled trial, four propensity-score matched cohorts, and one observational study included in this meta-analysis. The rate of MACE was lower in RA patients receiving statin [OR 0.67 (95%CI 0.51, 0.89), p=0.005; I2: 21.0%, p=0.29] (Figure 2). Sensitivity analysis using fixed-effect model showed that MACE was lower in the statin group [OR 0.73 (95%CI 0.62, 0.87), p<0.0051 I2: 21.0%, p=0.29]. Mortality was lower in RA patients receiving statin [OR 0.73 (95%CI 0.62, 0.88), p<0.001; I2: 29.0%, p=0.25] (Figure 3). Sensitivity analysis using fixed-effect model showed that mortality was lower in the statin group [OR 0.75 (95%CI 0.66, 0.85), p<0.001 I2: 29.0%, p=0.25]. CONCLUSIONS: This systematic review and meta-analysis showed that statin was associated with reduction of MACE and mortality in patients with RA.
