The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF Registry) is a pioneering real-world prospective registry - one of the largest in the field of non-valvular atrial fibrillation (AF). With an eventual enrolment target of 55,000 patients, GARFIELD-AF aims to enhance understanding of stroke prevention in patients with non-valvular AF worldwide and help in defining future treatment strategies that may eventually influence patient outcomes.
