HAS-BLED
Major bleeding risk on anticoagulation in atrial fibrillation
0
0–2 — lower risk
Bleeding risk does not by itself argue against anticoagulation.
Designed to flag modifiable bleeding risk, not to deny anticoagulation. Most factors it counts are also stroke-risk factors.
Interpretation
- 0–2 — lower risk — Bleeding risk does not by itself argue against anticoagulation.
- ≥ 3 — high risk — Address modifiable factors and review more often. A high score is NOT a reason to withhold anticoagulation.
Designed to flag modifiable bleeding risk, not to deny anticoagulation. Most factors it counts are also stroke-risk factors.
