Abstract W P339: Anticoagulation Remains Underutilized in the Management of Atrial Fibrillation: Results From the Edmonton Registry of Atrial Fibrillation and StrokE (ERASE) Study

Background: Since 2010, three novel oral anticoagulants (NOAC) have been approved and included in the guidelines as alternatives to warfarin for the prevention of stroke in patients with non-valvular atrial fibrillation (NVAF). Prior to the introduction of NOACs, studies showed that anticoagulation with warfarin in stroke patients with NVAF is suboptimal with as few as 40% anticoagulated and most subtherapeutic. The goal of this study is to examine anticoagulation usage in a contemporary prospective registry of TIA/stroke patients with NVAF and determine whether the introduction of NOACs has increased anticoagulation usage. Methods: This is an ongoing single centre observational study. Consecutive TIA/ischemic stroke admissions (2012-13) to a tertiary hospital in Edmonton, Canada with NVAF were enrolled. Data regarding demographic, clinical, antithrombotic treatment and laboratory parameters were collected in a prospectively maintained database. Those with previously diagnosed NVAF were included in the pr...
