Bleeding Risk in Atrial Fibrillation: HAS-BLED Score
Understand the risk of bleeding from anticoagulation in atrial fibrillation
The HAS-BLED score was derived from a real-world cohort of 3978 with AF and assesses the 1-year risk for major bleeding (intracranial, hospitalization, hemoglobin decrease >2 g/L, and/or transfusion) associated with oral anticoagulation. Patients with a high risk of bleeding (HAS-BLED score ≥ 3) should undergo regular clinical review following the initiation of oral anticoagulation.
