Official title
Randomized Trial of Apixaban vs Dose Adjusted Warfarin in Reducing Rate of Cognitive Function Decline, Silent Cerebral Infarcts and Cerebral Microbleeds in Non-valvular Atrial Fibrillation Patients With CHA2DS2-VaSc Score = 2
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators' central hypothesis is that in patients with atrial fibrillation, anticoagulation with Apixaban reduces the rate of decline in cognitive function, when compared to Warfarin. The investigators also hypothesize that Apixaban reduces cognitive decline by reducing the rate of new cerebral infarction and cerebral microbleeds detected by cerebral MRI compared to warfarin.
