CHA2DS2-VASc Score Calculator
Stroke risk stratification in non-valvular atrial fibrillation.
CHA₂DS₂-VASc Criteria
Select all criteria that apply:
CHA₂DS₂-VASc Score
0/9
Annual Stroke Rate: 0%
Total Score
0/9
Stroke Rate
0%
Recommendation
No anticoagulation
Treatment Guidelines
- Score 0 (male) / 1 (female): No anticoagulation
- Score 1 (male) / 2 (female): Consider anticoagulation
- Score ≥2 (male) / ≥3 (female): Anticoagulation recommended
Female Sex Modifier
Female sex is considered a "risk modifier" rather than a risk factor. It increases stroke risk only when other risk factors are present. CHA₂DS₂-VASc 1 (female only) = true low risk.
