Calculate the CHA₂DS₂-VASc score for atrial fibrillation to estimate annual stroke risk and see if anticoagulation is recommended per ESC guidelines.
The CHA₂DS₂-VASc score estimates annual stroke risk in patients with non-valvular atrial fibrillation and guides anticoagulation decisions. A score of 0 in men (or 1 in women) is low risk; a score of 1 in men (or 2 in women) suggests anticoagulation may be considered; a score of 2 or more in men (or 3 or more in women) warrants anticoagulation.
The score is a decision aid, not a substitute for clinical judgment. Always weigh stroke risk against bleeding risk (e.g. HAS-BLED) and individual patient factors before starting anticoagulation.
Enter the values for the scenario you are assessing. Calculate the CHA₂DS₂-VASc score for atrial fibrillation to estimate annual stroke risk and see if anticoagulation is recommended per ESC guidelines. Use the cha₂ds₂-vasc result to inform your calculation.
