HAS-BLED Score Calculator
The HAS-BLED score is a tool used to estimate the risk of bleeding in patients with atrial fibrillation. This calculator helps healthcare professionals to quickly assess bleeding risk based on multiple factors.
Calculate Your HAS-BLED Score
Check if the patient has uncontrolled hypertension.
Check if the patient has abnormal liver or renal function.
Results
HAS-BLED Score:
0
Bleeding Risk:
Low
Data Source and Methodology
All calculations are based on the HAS-BLED scoring system as described in the scientific literature. For more details, refer to the ESC Guidelines. All calculations are rigorously based on the formulas and data provided by this source.

$$ \text{HAS-BLED Score} = \text{Hypertension} + \text{Abnormal Liver/Renal Function} + \ldots $$
Glossary of Terms
- Hypertension: Elevated blood pressure.
- Abnormal Liver/Renal Function: Any significant liver or kidney dysfunction.
