Calculate CHA₂DS₂-VASc score for stroke risk assessment in atrial fibrillation. Enter clinical risk factors to determine anticoagulation need.
Score 0 (males) or 1 (females): Low risk, may not need anticoagulation. Score 1 (males): Moderate risk, consider anticoagulation. Score ≥2: High risk, anticoagulation recommended.
Studies show that women with atrial fibrillation have a higher stroke risk than men. However, female sex alone (score 1) does not warrant anticoagulation without other risk factors.
This calculator is for educational purposes. Treatment decisions should be made with your cardiologist, considering bleeding risk (HAS-BLED score), patient preferences, and individual circumstances.
