Today @JAMACardio published our study on potential risk/benefit of anticoagulation for #AFib pts aged 65-74 yrs w/out other CHADS2Vasc risk factors. This is one of the greatest areas of divergence of @SCC_CCS guidelines from @ACCinTouch @escardio

This study was prompted by a patient with #afib who challenged me to justify my recommendation to anticoagulate her on her 65th birthday for rest of her life. She asked what her risk of stroke is if she chose not to anticoagulate & if it outweighs bleeding risk.
When stroke risk exceeds 0.9% per year, people with #atrialfib likely benefit from newer and safer bloodthinners (DOACs) but are unlikely to benefit from the older cheaper bloodthinner known as warfarin unless their stroke risk exceeds 1.7% per year.
