Use of oral anticoagulant drugs in older patients with atrial fibrillation in internal medicine wards

Atrial fibrillation (AF) is independently associated with a higher risk of morbidity and mortality, in particular with an increased risk of thromboembolic events [1]. Use of oral anticoagulant (OAC) drugs reduces the risk of stroke and systemic embolism, as well as mortality among patients with AF [1].
