Introduction: Oral anticoagulation (OAC) substantially reduces stroke risk in patients with atrial fibrillation (AF) at risk for stroke. Whether non-vitamin K-dependent oral anticoagulants (NOACs) improve OAC use in stroke prevention requires investigation.
Methods: To investigate temporal trends of OAC use in patients with known AF pre-stroke, we retrospectively analyzed records of 6,803 stroke patients admitted in 2003-2004 (n=1,496), 2008-2010 (n=1,638) or 2013-2015 (n=3,669) to the Charité-Universitätsmedizin Berlin, Germany.
Aims: Therapeutic oral anticoagulation on hospital admission reduces morbidity and mortality after acute ischaemic stroke in patients with atrial fibrillation (AF). The underlying mechanism is not fully understood. In order to assess the impact of INR-level on admission on stroke volume, lesion pattern and the frequency of intracranial arterial occlusion, we analysed serial MRI measurements in AF patients suffering acute ischaemic stroke.
