Predictive Value of the HAS-BLED and ATRIA Bleeding Scores for the Risk of Serious Bleeding in a “Real-World” Population With Atrial Fibrillation Receiving Anticoagulant Therapy

The HAS-BLED score shows significantly better prediction accuracy than the weighted (and more complex) ATRIA score. Our findings reinforce the incremental usefulness of the simple HAS-BLED score over other published bleeding risk scores in patients with AF receiving anticoagulant therapy.
