CHA2DS2-VASc
Annual stroke-risk stratification in nonvalvular atrial fibrillation.
Result
0
Anticoagulation is generally recommended at 2 or more (men) / 3 or more (women); at 1 (men) / 2 (women) it is considered.
- Interpretation
- Higher scores mean higher annual stroke risk; guidelines anchor anticoagulation thresholds to it.
- Limitations
- Applies to nonvalvular AF; bleeding risk is a separate assessment, and the score does not capture every risk modifier.
- Reference
- Lip GY et al. Chest 2010;137:263-72.
