OBJECTIVE: Non-vitamin K antagonist oral anticoagulants (NOACs) have been proposed as alternatives to vitamin K antagonists (VKAs). The aim of this study is to examine the efficacy and safety of NOACs compared with warfarin with composite end points in patients with atrial fibrillation.
METHODS: This semi-systematic review performed a study of Phase III randomized controlled trials comparing NOACs with vitamin K antagonists (VKAs) in patient with atrial fibrillation using composite end points (combination of various clinical events). The use of composite end points allowed for combining efficacy and safety outcomes, thereby comparing the differences between NOAC and warfarin therapy from a clinical perspective.
RESULTS: Treatment with NOAC compared with warfarin was associated with a significant reduction in the sum of stroke or non-CNS, systemic embolism and major bleeding (odds ratio 0.87; 95% CI: 0.82-0.91).
CONCLUSION: Generally, NOACs were associated with a more favorable efficacy and safety profile compared with warfarin with regard to composite end points.
