GARFIELD-AF Risk Score — Atrial Fibrillation Stroke and Bleeding Risk

The GARFIELD-AF (Global Anticoagulant Registry in the FIELD-Atrial Fibrillation) Risk Score is a validated prediction model derived from a large multinational real-world registry of > 50,000 patients with newly diagnosed non-valvular atrial fibrillation to simultaneously predict 1-year all-cause mortality, stroke/systemic embolism, and major bleeding. Unlike CHA₂DS₂-VASc which only predicts stroke risk, GARFIELD-AF provides competing risk estimates to aid in the individualized benefit-risk assessment of anticoagulation therapy — allowing comparison of ischemic stroke prevention benefit vs. bleeding risk for individual AF patients.
