Design outcomes

Primary

MeasureTime frame
Main Objective: To compare the combined risks of severe bleedings and thrombosis of oral anticoagulation versus no anticoagulation in haemodialysis patients with atrial fibrillation;Secondary Objective: To compare oral anticoagulation to no anticoagulation in haemodialysis patients with atrial fibrillation, regarding the risk of thrombosis and morbi-mortality;Primary end point(s): Combined endpoint: Incidence of severe non-fatal (type 3a, 3b, 3c in the classification from the Bleeding Academic Research Consortium) (Mehran 2011) and fatal bleedings (type 5) plus Incidence of non-fatal and fatal strokes according to the therapeutic strategy, during 24 months.;Timepoint(s) of evaluation of this end point: During 24 months

Secondary

MeasureTime frame
Secondary end point(s): a) Incidence cumulée des évènements du critère d’évaluation principal. b) Incidence des hémorragies graves non mortelles (type 3a, 3b, 3c) en fonction de la stratégie thérapeutique c) Incidence des hémorragies fatales (type 5) en fonction de la stratégie thérapeutique d) Incidence des hémorragies graves non mortelles (type 3a, 3b, 3c) et des hémorragies fatales (type 5) en fonction de la stratégie thérapeutique e) Incidence des accidents vasculaires cérébraux non mortels en fonction de la stratégie thérapeutique f) Incidence des accidents vasculaires cérébraux mortels en fonction de la stratégie thérapeutique g) Incidence des accidents vasculaires cérébraux mortels et non mortels en fonction de la stratégie thérapeutique h) Incidence des hémorragies non mortelles et mortelles et des accidents vasculaires cérébraux mortels et non mortels en fonction de la stratégie thérapeutique i) Incidence des hémorragies fatales (type 5) et des accidents vasculaires cérébraux mortels en fonction de la stratégie thérapeutique j) Incidence des événements cardiovasculaires athérothrombotiques majeurs (MACE) en fonction de la stratégie thérapeutique k) L’incidence des événements athérothrombotique cardiovasculaires majeurs (MACE) et des décès cardiovasculaires en fonction de la stratégie thérapeutique l) Incidence de la mortalité toutes causes confondues selon la stratégie thérapeutique m) Validation formelle des scores de risques CHAD2VSAC et HASBLED chez les patients dialysés n) Comparaison des risques de la FA persistante ou permanente versus paroxystique o) Déclin cognitif en fonction de la stratégie thérapeutique ;Timepoint(s) of evaluation of this end point: During 24 months
