Introduction
Vitamin K antagonists (VKAs) reduce the risk of stroke in patients with atrial fibrillation (AF). For more than five decades, they were the only available treatment. Novel oral anticoagulants (NOACs) have recently been approved for the prevention of non-valvular AF-related stroke. Dose-adjusted VKA therapy and NOACs are highly effective in AF patients. However, dabigatran, rivaroxaban and apixaban are more convenient, while at least equally effective and with a comparable safety profile (regarding bleeding complications) for stroke prevention compared with VKAs.1-3
Recent guidelines prefer treatment with NOACs over VKAs for most
