Background: There is controversy surrounding the effectiveness of red blood cell (RBC) transfusion for treating anemia in patients hospitalized for acute coronary syndromes (ACS), particularly as hemoglobin (Hb) levels approach and drop below the range of moderate anemia.
Methods: This population-based cohort study followed all adults hospitalized for ACS who experienced an in-hospital nadir Hb between 6.0 and 8.
Background: Despite many atrial fibrillation (AF) patients being at risk of bleeding, very limited data are available on bleeding rates of different direct oral anticoagulants based on the spectrum of bleeding risk.
Objective: We aimed to compare the risk of major bleeding and thromboembolic events with apixaban vs rivaroxaban for AF patients stratified by bleeding risk.
Methods: We conducted a population-based, retrospective cohort study of all adult patients (66 years or older) with AF in Ontario, Canada, who were treated with apixaban or rivaroxaban between April 1, 2011, and March 31, 2020.
