Abstract

BACKGROUND: Prevention of ischemic stroke is an essential part of managing atrial fibrillation (AF). In recent years, direct oral anticoagulants (DOACs) have emerged as an alternative to vitamin K antagonists (VKAs). Little is understood regarding the efficacy and safety of DOACs in AF patients with liver cirrhosis (LC). OBJECTIVE: This meta-analysis is designed to evaluate the benefits and risks of DOACs compared to VKAs in AF patients with concomitant LC. METHODS: A thorough search was conducted in PubMed, Cochrane Library, Web of Science, Embase, Scopus, and CNKI databases up to February 2023. A total of seven clinical studies including 7551 patients were analyzed in this meta-analysis. All data analyses were performed using Review Manager software version 5.3. RESULTS: Regarding efficacy outcomes, DOACs had comparable clinical benefit in reducing ischemic stroke/systemic thromboembolism (HR=0.79, 95% CI [0.59, 1.06], p = 0.12) to VKAs. The incidence of all-cause death was similar between the DOACs and VKAs group (HR 0.94, 95% CI [0.69, 1.28], p = 0.69). Regarding safety outcomes, DOACs were associated with a significantly lower risk of major bleeding (HR 0.61, 95% CI [0.50, 0.75], p < 0.00001), intracranial hemorrhage (HR 0.55, 95% CI [0.31, 0.98], p = 0.04) and major gastrointestinal bleeding (HR 0.66, 95% CI [0.51, 0.85], p = 0.001) than VKAs. Additional subgroup analysis of advanced cirrhosis revealed that DOACs were associated with a significantly lower risk of major bleeding (HR 0.59, 95% CI [0.39, 0.89], p = 0.01) than VKAs. There were no significant differences between the DOACs and VKAs group concerning the incidence of ischemic stroke/systemic thromboembolism (HR 1.38, 95% CI [0.75, 2.55], p = 0.31) and major gastrointestinal bleeding (HR 0.65, 95% CI [0.41, 1.04], p = 0.08). CONCLUSION: DOACs are associated with more favorable safety outcomes and may be a feasible option of oral anticoagulant for individuals with atrial fibrillation and cirrhosis. Pending validation by randomized prospective studies, the findings of this study should be interpreted with caution.

Key Findings

Regarding efficacy outcomes, DOACs had comparable clinical benefit in reducing ischemic stroke/systemic thromboembolism (HR=0.79, 95% CI [0.59, 1.06], p = 0.12) to VKAs. The incidence of all-cause death was similar between the DOACs and VKAs group (HR 0.94, 95% CI [0.69, 1.28], p = 0.69). Regarding safety outcomes, DOACs were associated with a significantly lower risk of major bleeding (HR 0.61, 95% CI [0.50, 0.75], p < 0.00001), intracranial hemorrhage (HR 0.55, 95% CI [0.31, 0.98], p = 0.04) a
