Total Score
Low risk of major bleeding (~1-2%). Anticoagulation generally safe.

The HAS-BLED score is a widely used clinical tool designed to assess the 1-year risk of major bleeding in patients with atrial fibrillation receiving oral anticoagulation. It assists clinicians in identifying modifiable bleeding risk factors and scheduling closer follow-ups for high-risk individuals.
A high HAS-BLED score (≥3) is NOT a contraindication to anticoagulation. The ischemic stroke risk usually outweighs the bleeding risk. The primary utility of this score is to identify and correct modifiable factors (e.g., uncontrolled hypertension, concomitant NSAID use, excessive alcohol intake).
