Score used
CHA2DS2-VASc
Published annual stroke rate
3.2 %
Rate taken from
Swedish Atrial Fibrillation cohort (Friberg 2012, n = 182,678, without anticoagulation); annual ischaemic stroke rate
Risk category
Moderate
Against the guideline threshold
At or above the ESC 2020 threshold (>= 3 for a woman) at which oral anticoagulation carries a Class I recommendation.
Worked out from Gage BF, Waterman AD, Shannon W, et al. Validation of clinical classification schemes for predicting stroke: results from the National Registry of Atrial Fibrillation and 4 other sources.
A risk score, not a treatment decision. The published rates come from specific historical cohorts of patients who were not anticoagulated and may not describe any individual today. Whether to anticoagulate is a clinical decision that also weighs bleeding risk, kidney function and patient preference.
How this is worked out
4 steps
- Scoring with CHA2DS2-VASc (maximum 9).
- Hypertension +1, Age 65 to 74 +1, Female sex +1.
- Total = 3.
- Swedish Atrial Fibrillation cohort (Friberg 2012, n = 182,678, without anticoagulation); annual ischaemic stroke rate: 3.2% at a score of 3.
