Brief Summary:
Apixaban is an anticoagulant which is increasingly being used to prevent stroke in atrial fibrillation (AF). Phase III clinical trials have demonstrated that apixaban is efficacious and safe for the overall AF population; however, patients older than age 85, with creatinine clearance \<40mL/min, or who weighed \<50kg were poorly represented in these trials, yet they are commonly seen in real-world clinical scenarios. Advanced age, poor renal function, and low body weight are all associated with elevated drug levels, and elevated drug levels are associated with an increased risk of bleeding. Therefore, clinicians are concerned about the risk of bleeding and are unsure of how best to treat this patient population. Although other anticoagulants are available, apixaban is attractive because it has a low rate of bleeding, low dependence on the kidneys for clearance, and does not require frequent ongoing monitoring and dose adjustment. This study will include patients taking apixaban who were not well-represented in phase III trials - those with age \>85, creatinine clearance \<40mL/min, or weight \<50kg - who are also at increased risk of having elevated drug levels due to these clinical characteristics. Participants will have apixaban levels measured, and those with persistently elevated levels will have their dose reduced. Drug levels will be measured again after dose reduction to determine if the levels are reduced without becoming dangerously low.
