Resumen:
Introduction and objectives: Evidence for the efficacy and safety of oral anticoagulation with dicumarines in patients with atrial fibrillation (AF) on hemodialysis is controversial. The aim of our study is to evaluate the long-term prognostic implications of anticoagulation with dicumarines in a cohort of patients with non-valvular AF on a hemodialysis program due to end-stage renal disease.
Methods: Retrospective, observational study with consecutive inclusion of 74 patients with AF on hemodialysis. The inclusion period was from January 2005 to October 2016. The primary variables were all-cause mortality, non-scheduled readmissions and bleeding during follow-up.
Results: Mean age was 75 10 years; 66.2% were men and 43 patients (58.1%) received acenocoumarol. During a median follow-up of 2.40 years (IQR = 0.88-4.15), acenocoumarol showed no survival benefit [HR= 0.76, 95% CI (0.35-1.66), p = 0.494]. However, anticoagulated patients were at increased risk of recurrent cardiovascular hospitalizations [IRA= 3.94, 95% CI (1.06-14.69), p=0.041]. There was a trend towards an increase in repeated hospitalizations of ischemic cause in anticoagulated patients [IRR = 5.80, 95% CI (0.86-39.0), p = 0.071]. There was a statistical trend towards a higher risk of recurrent total bleeding in patients treated with acenocoumarol [IRR= 4.43, 95% CI (0.94-20.81), p = 0.059].
Conclusions: In this study, oral anticoagulation with acenocoumarol in patients with AF on hemodialysis did not increase survival. However, it was associated with an increased risk of hospitalizations of cardiovascular causes and a tendency to an increased risk of total bleeding. (C) 2018 Sociedad Espanola de Nefrologia.
