CHA₂DS₂-VASc Score Calculator
CHA₂DS₂-VASc Score
Calculate stroke risk score for atrial fibrillation patients
Formula
CHA₂DS₂-VASc = CHF(1) + Hypertension(1) + Age>=75(2) + Diabetes(1) + Stroke/TIA(2) + Vascular Disease(1) + Age 65-74(1) + Female Sex(1) | Max Score = 9
Frequently Asked Questions
What does CHA₂DS₂-VASc stand for?
C = Congestive heart failure (+1), H = Hypertension (+1), A₂ = Age >= 75 (+2), D = Diabetes (+1), S₂ = Stroke/TIA/thromboembolism (+2), V = Vascular disease (+1), A = Age 65-74 (+1), Sc = Sex category female (+1). Maximum score is 9.
When should anticoagulation be started based on the score?
Current guidelines recommend anticoagulation for men with a score >= 1 (if the point is not from female sex alone) and for all patients with a score >= 2. A score of 0 in men (or 1 in women from sex category alone) suggests no anticoagulation needed.
What anticoagulants are used for AFib?
Options include direct oral anticoagulants (DOACs) such as apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa), and edoxaban (Savaysa), or warfarin (Coumadin). DOACs are generally preferred due to fewer interactions and no routine monitoring requirement.
