Brief Summary:

Guidelines recommend oral anticoagulation with vitamin K antagonists for atrial fibrillation whenever the CHADS2VASC score is superior or equal to 2. As there are no specific guidelines for the hemodialysis patients with atrial fibrillation, the general guidelines apply. However, several retrospective studies suggest that these patients do not benefit from the oral anticoagulation regarding the risk of stroke and may even experience more bleedings and deaths.

The aim of this prospective study is to prospectively compare the hemorrhagic and thrombotic risks of oral anticoagulation in comparison with no anticoagulation in hemodialysis patients with atrial fibrillation.

Condition or disease Intervention/treatment Phase
Kidney Failure, Chronic Biological: No oral anticoagulation Drug: Oral anticoagulation with vitamin K antagonists Phase 4

Resource links provided by the National Library of Medicine

Drug Information available for: Menadione

Arm Intervention/treatment
Experimental: No anticoagulation
No oral anticoagulation, and no monitoring of the INR.
Biological: No oral anticoagulation
No oral anticoagulation, and no monitoring of the INR.

Active Comparator: Oral anticoagulation with vitamin K antagonists

VKA use as recommended in the guidelines with INR target range between 2 and 3. Daily administration or thrice weekly at the end of dialysis sessions upon Nephrologist's choice.

Antiplatelet therapy will be provided only if recent acute coronary syndrome (< 6 months) or active coronary stent. Aspirin should be preferred in dialysis patients as clopidogrel has an unpredictable reduced activity and there is no safety data on combination of VKA with prasugrel or ticagrelor in this population.

Drug: Oral anticoagulation with vitamin K antagonists

Vitamin K antagonist prescription with INR target between 2 and 3 as recommended in the guidelines.

Administration once daily or at the end of each dialysis session, according to the nephrologist choice.

INR monitoring at least once per week

Primary Outcome Measures :
  1. Cumulative incidence of severe bleedings and thrombosis of oral anticoagulation versus no anticoagulation in hemodialysis patients with atrial fibrillation [ Time Frame: 2 years ]
