Work out cha2ds2 vasc score instantly with clear inputs, formula shown and shareable results.
Sums the CHA2DS2-VASc components — age, sex, heart failure, hypertension, diabetes, vascular disease and prior stroke — and reports the published annual stroke rate.
CHA2DS2-VASc
Age >=75 = 2, age 65-74 = 1, female sex = 1, prior stroke/TIA = 2, plus 1 each for heart failure, hypertension, diabetes and vascular disease (maximum 9)
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Female sex is a risk modifier rather than an independent factor, which is why the treatment threshold is one point higher in women.
The annual stroke rates come from the large Swedish cohort published by Friberg and colleagues.
