CHA(2)DS2-VASc score: heart failure, hypertension, age≥75 years, diabetes, previous stroke/TIA, vascular disease, age 65-74 years, sex female. 1 point each, except age>75
DISEASE INTERVENTION COMPARISON RESULTS
Chest. 2010 Feb;137(2):263-72 Cohorts
IN atrial fibrillation, stroke, ischemic, cerebral infarction, embolic, peripheral embolism The Use of
CHA(2)DS2-VASc score: heart failure, hypertension, age≥75 years, diabetes, previous stroke/TIA, vascular disease, age 65-74 years, sex female. 1 point each, except age>75 & previous stroke, 2 points
As Prognostic Item
Is better Than
CHADS2 and other scores
To predict risk of stroke and peripheral embolism, at 1year, specially in patients at low risk: 0% if 0 points; 0,7% if 1 point; 1.9% if 2 points; 4.7% if 3 points. Less accuracy at scores 4,5 and 6, but fewer patients classified as "intermediate risk"
