[Increased risk of bleeding in patients with atrial fibrillation and chronic kidney disease on hemodialysis treated with anticoagulants. A four center serie].

Background: Because the benefits and risks of anticoagulation are still unknown in patients with atrial fibrillation (AF) and with chronic kidney disease (CKD) on hemodialysis.

Objective: The aim of this study was to estimate whether the consumption of anticoagulants was associated with a difference in the frequency of thrombosis of any site, major bleeding and mortality, in adults with both diseases.

Method: A retrospective cohort study was carried out in four high complexity centers.
