Abstract
BACKGROUND: Dabigatran is a kind of oral anticoagulant and there was little review only about dabigatran and warfarin used in patients with atrial fibrillation. This meta-analysis only assesses the dabigatran and warfarin used in patients with atrial fibrillation.
DESIGN: Cochrane Library, PubMed, Clinical Trials.gov, CNKI, and WanFang databases were searched. The primary endpoint was the incidence of stroke and the second endpoints were the incidence of bleeding and embolic events.
RESULTS: Six RCTs and 20086 patients were included in our meta-analysis. No significant difference was obtained between 110 mg dabigatran and warfarin on the endpoint of stroke (risk ratio (RR), 0.90; 95% confidence interval [CI], 0.71-1.12; P = .34; I = 0%) and embolic events p (RR, 0.89; 95% CI, 0.71-1.12; P = .32; I = 0%). However, the 110 mg dabigatran associated lower incidence of bleeding (RR, 0.81; 95% CI, 0.69-0.95; P = .01; I = 0%) compare with warfarin. When compared with 150 mg dabigatran, warfarin associated with lower rate of stroke (RR, 0.96; 95% CI, 0.83-1.12; P = .62; I = 0%) and embolic events (RR, 0.67; 95% CI, 0.53-0.86; P = .001; I = 0%) but similar in the incidence of bleeding (RR, 0.67; 95% CI, 0.53-0.86; P = .001; I = 0%).
CONCLUSION: No significant difference was obtained between 110 mg dabigatran and warfarin in the incidence of stroke and embolic events. However, the 110 mg dabigatran associated lower incidence of bleeding compare with warfarin. When compared with 150 mg dabigatran, warfarin associated with lower incidence of stroke and embolic events but similar in the incidence of bleeding.
