BackgroundThe effect of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) and liver disease remains largely unresolved. Therefore, we performed a meta-analysis to compare the efficacy and safety of NOACs with warfarin in this population.MethodsWe systematically searched the Cochrane Library, PubMed, and Embase databases for studies reporting the comparisons of NOACs with warfarin in patients with AF and liver disease. A random-effects model was selected to pool the risk ratios (RRs) and 95% confidence intervals (CIs).ResultsA total of six studies with 41,954 participants were included in this meta-analysis. In AF patients with liver disease, compared with warfarin use, the use of NOACs was associated with reduced risks of all-cause death (RR 0.78, 95% CI 0.66-0.93), major bleeding (RR 0.68, 95% CI 0.53-0.88), and intracranial hemorrhage (RR 0.49, 95% CI 0.41-0.59), but had comparable risks of stroke or system embolism (RR 0.80, 95% CI 0.57-1.12) and gastrointestinal bleeding (RR 0.90, 95% CI 0.61-1.34). In AF patients with cirrhosis, NOACs significantly reduced the risks of major bleeding (RR 0.53, 95% CI 0.37-0.76), gastrointestinal bleeding (RR 0.57, 95% CI 0.38-0.84), and intracranial hemorrhage (RR 0.55, 95% CI 0.31-0.97) compared with warfarin.ConclusionsBased on current publications, the use of NOACs is at least non-inferior to warfarin in patients with AF and liver disease.
