Evaluation of the Risk of Stroke Without Anticoagulation Therapy in Men and Women With Atrial Fibrillation Aged 66 to 74 Years Without Other CHA2DS2-VASc Factors

Canadian cohort study (n=16,351) found stroke risk more than doubled as men & women with AF but no other CHA2DS2-VASc risk factors aged from 66 to 74 years (from 0.7% at 66 years to 1.7% at 74 years) suggesting anticoagulation more likely to benefit older than younger individuals
