Stroke risk profile: CHADS2 / CHA2DS2-VASc What do we know about risk in GARFIELD-AF? Stroke risk profile: CHADS2 / CHA2DS2-VASc Percentage Percentage
Preliminary first year event rates according to number of risk factors RF, risk factor (heart failure, LVEF <40%, hypertension, age ≥75, diabetes, previous stroke/TIA/SE, vascular disease, age 65–74 years, female gender) Kakkar A, AHA-2012
Poster presentation at ESC ‘Truly low-risk’ patients with newly diagnosed non-valvular atrial fibrillation at risk of stroke: 1-year outcomes from the GARFIELD-AF Registry Jean-Pierre Bassand et al., for the GARFIELD-AF Investigators Tuesday, 2 September from 14:00–18:00 in the poster area of the Central Village
Rate of stroke/systemic embolism according to CHA2DS2-VASc score of 0 versus 1-9: 0.2% 1.1%
Conclusions In patients with A-Fib, the estimation of individual risk of stroke is key before any therapeutic decision is made CHA2DS2-VASc is recommended as the primary instrument in estimating risk of stroke (ESC 2012 / AHA+ACC 2014) The focus is to identify truly low-risk patients – these will not need anticoagulation therapy All other patients ought to receive anticoagulation for the indication of “SPAF”
