Antikoagulation bei Vorhofflimmern

Abstract

SummaryAtrial fibrillation is one of the most frequent reasons for therapeutic anticoagulation in everyday practice. Oral vitamin K antagonists such as Marcumar have been state of the art anticoagulants to prevent thrombembolic events in patients with atrial fibrillation and additional risk factors. But these drugs are accompanied by disadvantages such as increased bleeding risk and impaired quality of life caused by interactions with food or other medications as well as frequent controls of INRs.The new anticoagulants apixaban, rivaroxaban and dabigatran are direct antagonists of coagulation factors (FXa or FIIa) and demonstrate a promising risk/benefit profile in large clinical trials compared with vitamin K antagonists.Their approval for clinical use will open up new therapeutic perspectives for patients with atrial fibrillation and indication for anticoagulation.
