HAS-BLED is a scoring system developed to assess 1-year risk of major bleeding in people taking anticoagulants for atrial fibrillation (AF).
[1] HAS-BLED is a medical tool used to calculate the one-year risk of major bleeding for people on blood thinning drugs for atrial fibrillation (AF).
[3] Abnormal liver function: Cirrhosis or Bilirubin >2x Normal or AST/ALT/AP >3x Normal Medication Usage Predisposing to Bleeding: (Antiplatelet agents, NSAIDs) A calculated HAS-BLED score is between 0 and 9 and based on seven parameters with a weighted value of 0-2.
[4] Mixed evidence exist on the comparison between GARFIELD-AF bleeding score over the HAS-BLED.
[8] The HAS-BLED score has also been validated in an anticoagulated trial cohort of 7329 people with AF - in this study, the HAS-BLED score offered some improvement in predictive capability for bleeding risk over previously published bleeding risk assessment schemas and was simpler to apply.
