HAS-BLED Bleeding Risk Calculator
The HAS-BLED score estimates the 1-year risk of major bleeding in patients with atrial fibrillation. Higher scores indicate greater bleeding risk.

HAS-BLED Score
0
Low Risk
Interpretation
Based on the calculated score, this patient has a low risk of major bleeding (approximately 1.1 bleeds per 100 patient-years).
| Score | Risk Category | Bleeds per 100 Patient-Years |
|---|---|---|
| 0 | Low | 1.1 |
| 1 | Low | 1.9 |
| 2 | Intermediate | 3.7 |
| 3 | Intermediate | 8.7 |
| 4 | High | 12.5 |
| ≥5 | High | >12.5 |
Note: The HAS-BLED score is a tool to assess bleeding risk, not a reason to withhold anticoagulation. High scores should prompt regular review and correction of modifiable risk factors.
