The Efficacy and Safety of Rivaroxaban in Coronary Artery Disease Patients with Heart Failure and Sinus Rhythm: a Systematic Review and Meta-analysis

Purpose: To explore the efficacy and safety of rivaroxaban in patients with coronary artery disease (CAD), heart failure (HF) and sinus rhythm (SR).

Methods: Comprehensive literature searches were conducted using the PubMed, Cochrane Library, Embase, CNKI and Wanfang databases from inception to February 2021. Randomized controlled trials (RCTs) focusing on the efficacy and safety of new oral anticoagulant (NOAC) therapy in CAD and HF patients in SR were eligible. Statistical analyses were performed using R Programming Language.

Results: Three RCTs included 10,658 adult patients treated with antiplatelet drugs with or without rivaroxaban were ultimately analysed. The average follow-up period was 20.4-24 months. Rivaroxaban had a favourable point estimate in myocardial infarction (MI) and stroke (MI rivaroxaban group (3.83%, 203/5306) vs. APT group (4.52%, 214/4731), RR = 0.78, 95% CI 0.65-0.94, P < 0.01, I = 0%), (stroke: rivaroxaban group (1.60%, 85/5306) vs. APT group (2.52%, 119/4731), RR = 0.64, 95% CI 0.49-0.85, P < 0.01, I = 12%) compared with the placebo. Rivaroxaban was comparable to the placebo for all-cause death and major bleeding (all-cause death: rivaroxaban group (12.27%, 688/5606) vs. APT group (14.59%, 737/5052), RR = 0.73, 95% CI 0.49-1.06, P > 0.05, I = 87%), (major bleeding: rivaroxaban group (1.52%, 85/5586) vs. APT group (1.37%, 69/5043), RR = 1.18, 95% CI 0.86-1.62, P > 0.05, I = 0%).

Conclusions: In SR patients with CAD and HF, the rates of MI and stroke associated with rivaroxaban combined with APT were lower than those associated with APT alone, and the two treatments had similar rates of all-cause death and major bleeding.
