Purpose of review Direct oral anticoagulants (DOACs) are variably eliminated by the kidneys rendering their use potentially problematic in patients with chronic kidney disease (CKD) or necessitating appropriate dose adjustment. Recent findings Both observational and limited randomized trial data for DOACs compared with no treatment or with warfarin for patients with atrial fibrillation on maintenance dialysis were recently published. In a randomized trial in patients on hemodialysis, there was no significant difference in vascular calcification between patients who received rivaroxaban with or without vitamin K2 or vi...

Cardiologists' and nephrologists' management of atrial fibrillation in hemodialysis patients
. Clin Nephrol. 2019 Sep 09;: Authors: Marcus L, Mackeigan L, Leblanc K, Orlov D, Mitsakakis N, Austin Z, Jassal SV, Battistella M Abstract BACKGROUND: Antithrombotic therapy for stroke prevention in atrial fibrillation (AF) is considered a standard of care, but for hemodialysis (HD) patients the benefits are unclear, and bleeding risks are high. Our study objective was to compare cardiologists' and nephrologists' stroke prevention practices in different patient risk scenarios. MATERIALS AND METHODS: A ...

Abstract Warfarin is the most commonly prescribed anticoagulant in hemodialysis (HD) patients with nonvalvular atrial fibrillation (NVAF). Recent trends show that Nephrologists are increasingly prescribing novel oral anticoagulants, despite the fact that no randomized clinical trials have been conducted in dialysis patients. Difficulties maintaining international normalized ratio in the therapeutic range, increased risk of intracranial hemorrhage and concerns regarding warfarin-induced vascular calcification and calciphylaxis may be responsible. Anticoagulation quality is poor in HD patients. A variety of factors ...

Conclusion A great impact on death, but not ischemic stroke, was observed in non-anticoagulated hemodialysis patients with AF in comparison to those without AF from the analysis of the RAKUEN study. PMID: 29607945 [PubMed - as supplied by publisher]

Abstract Chronic kidney disease (CKD) occurs in approximately one‐third of patients with non‐valvular atrial fibrillation (AF). The presence of CKD, particularly advanced CKD, confers increased risk of both thromboembolism and major bleeding in this group of patients who are already at risk for ischemic stroke and systemic embolism and at risk of bleeding due to anticoagulation. Studies assessing the effect of warfarin on risk of ischemic stroke, systemic embolism, and major bleeding have produced disparate results, particularly in patients with advanced CKD including those treated with hemodialysis. The direct oral an...

Background: Chronic kidney disease (CKD) is associated with a high prevalence of atrial fibrillation (AF), but in this population the risk/benefit ratio of anticoagulant therapy with vitamin K antagonists (VKA) for thromboprophylaxis is uncertain.Summary: In end-stage renal disease (ESRD) patients undergoing hemodialysis, VKA seem less effective in stroke prevention than in the general population, with an increased risk of major bleeding. Recently, novel oral anticoagulant agents (NOACs) have proven to be effective for stroke prevention in AF and have demonstrated an improved safety profile compared to VKA. Limited data fr...

Abstract The delicate balance of risk vs. benefit of using antiplatelet and antithrombotic agents in the general population is well established. The decision to use these agents in the end stage renal disease (ESRD) population remains complex and difficult. The concomitant association of a prothombotic state with high risk of bleeding in the ESRD population requires individualization and careful clinical judgment before implementing such therapy. There remains a paucity of clinical trials and lack of substantial evidence in literature for safe and effective use of antithrombotic drugs in patients with advanced chronic kidn...

The association between atrial fibrillation and stroke is well established, and in the general population, anticoagulation with warfarin can reduce the incidence of stroke by 60% with an acceptable bleeding risk.1,2 Patients who are on hemodialysis have an increased prevalence of atrial fibrillation, possibly secondary to comorbid conditions and hemodialysis itself causing dramatic swings in fluid and electrolytes and affecting cardiac dimensions.3 There are also substantially higher rates of ischemic stroke in this population attributable both to frequently co-occurring traditional stroke risk factors and to the increased...
