Common questions
What does AF Anticoagulation Decision (CHA₂DS₂-VASc + HAS-BLED) do?
Support the anticoagulation decision in non-valvular AF, including drug preference and bleeding-risk management.
How is the result calculated?
CHA₂DS₂-VASc (CHF, hypertension, age ≥ 75 [2], diabetes, prior stroke/TIA [2], vascular disease, age 65–74, female) vs HAS-BLED (uncontrolled BP, abnormal renal/liver function, stroke, bleeding, labile INR, age > 65, drugs/alcohol).
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
