A comparison of anticoagulation, antiplatelet, and placebo treatment for patients with heart failure reduced ejection fraction in sinus rhythm: a systematic review and meta-analysis

AbstractPrevious meta-analyses have not recommended routine warfarin use in heart failure (HF) patients but included limited data on contemporary anticoagulants and practices. We conducted an updated meta-analysis in light of newer literature evaluating rivaroxaban in this patient population. The aim of this meta-analysis was to assess if anticoagulation is associated with a decrease in all-cause mortality, myocardial infarction (MI), stroke, and hospitalization for HF exacerbation without an increased risk of major bleeding. A systematic search was conducted for randomized controlled trials to evaluate the use of antithrombotic therapy in patients with HF in sinus rhythm. Outcomes evaluated included all-cause mortality (ACM), non-fatal stroke, MI, hospitalization for HF exacerbation, and major bleeding. Five trials met criteria with a total of 9390 patients included. Four of the five trials evaluated warfarin use and one trial evaluated rivaroxaban. When anticoagulation was compared to control (antiplatelet and placebo groups), a significant reduction in ischemic stroke was found (OR 0.57; 95% CI, 0.42 to 0.78;P = 0.0005,I2 = 6.9%) and no significant difference was found in the risk of ACM, MI, or HF hospitalization. A significant increase in major bleeding was observed in the anticoagulation group when compared to the control group (OR 2.00; 95% CI, 1.45 to 2.75;P = <  0.0001,I2 = 25.79%). Anticoagulation in HF patients in normal sinus rhythm does not a...
