Abstrakt: Findings of prior studies about the efficacy and safety of non‐vitamin K antagonist oral anticoagulants (NOACs) in patients (≥80 years of age) with atrial fibrillation (AF) are controversial. So we performed a meta‐analysis to evaluate the efficacy and safety of NOACs versus vitamin K antagonists (VKAs) in patients (≥80 years of age) with AF. A systematic review of PubMed, Cochrane, Embase, Web of Science and Chinese BioMedical databases was conducted until 1 October 2022. Studies reporting the effects and safety of NOACs versus warfarin in patients (≥80 years of age) with AF were included. Two authors independently performed study selection and data extraction. Discrepancies were resolved by consensus or through an independent third reviewer. Data were synthesised according to the Preferred Reporting Items for Systematic Reviews guidelines. We identified 15 studies providing data of 70 446 participants (≥80 years of age) suffering from AF. According to the meta‐analysis (odds ratio (OR) (95% confidence interval, CI)), NOACs conferred better efficacy profile than VKAs in stroke and systemic embolism (0.8 (0.73–0.88)) and all‐cause mortality (0.61 (0.57–0.65)). Otherwise, NOACs conferred a better safety profile than VKAs in major bleeding (0.76 (0.70–0.83)) and intracranial haemorrhage (ICH; 0.57 (0.47–0.68)). In conclusion, for patients (≥80 years of age) with AF, the risks of stroke and systemic embolism, all‐cause mortality, were lower in NOACs compared to warfarin. The risks of major bleeding and ICH were also lower in NOACs compared to warfarin. NOACs showed better efficacy and safety than warfarin. [ABSTRACT FROM AUTHOR]
