Atrial Fibrillation Research Database

All patients with atrial fibrillation who are treated with vitamin-k antagonists (warfarin, phenprocoumon) or non vitamin K oral anticoagulants (Dabigatran, Rivaroxaban, Apixaban, Edoxaban) in real world settings will be recorded in this register. Within this register a characterization of patients and therapy (with regard to medication, dose and duration) will be done. On basis of defined clinical relevant end points the long-term efficacy and safety will be evaluated.
