CHA2DS2-VA Score
Estimates stroke risk in atrial fibrillation without using sex as a factor.
When to use
Thromboembolic risk stratification in adults with atrial fibrillation using the version without sex.
Pearls and pitfalls
- The VA version removes female sex and keeps the other CHA2DS2-VASc factors.
- Age 75 or older scores 2 points; age 65 to 74 scores 1 point.
- Previous stroke, TIA or thromboembolism scores 2 points.
- The score estimates risk and does not replace bleeding assessment or shared decision making.
0/9 points
Low risk
No risk factors by the score; reassess periodically.
Formula
Sum heart failure, hypertension, diabetes and vascular disease at 1 point each; age 65 to 74 at 1; age 75 or older, stroke, TIA or thromboembolism at 2.
Evidence
Score adopted by the 2024 European atrial fibrillation guideline, derived from CHA2DS2-VASc without the sex component.
