Understanding CHA2DS2-VASc Score
The CHA2DS2-VASc score is used to predict stroke risk in patients with atrial fibrillation. It helps doctors decide if blood thinners (anticoagulants) are needed.
Score Interpretation:
- Score 0: Low risk (1.9% annual stroke risk) - No anticoagulation usually recommended
- Score 1: Moderate risk (2.0% annual stroke risk) - Consider anticoagulation
- Score 2: Moderate-High risk (3.7% annual stroke risk) - Anticoagulation recommended
- Score 3: High risk (5.3% annual stroke risk) - Anticoagulation strongly recommended
- Score 4: High risk (6.7% annual stroke risk) - Anticoagulation strongly recommended
- Score ≥5: Very high risk (≥8.9% annual stroke risk) - Anticoagulation strongly recommended
CHA2DS2-VASc Components:
- C: Congestive Heart Failure
- H: Hypertension
- A: Age ≥ 75 (2 points)
- D: Diabetes
- S: Prior Stroke/TIA (2 points)
- V: Vascular Disease
- A: Age 65-74
- S: Sex (Female)
