Stroke Prophylaxis in Patients with Atrial Fibrillation and End-Stage Renal Disease.

ABSTRACT: Atrial fibrillation (AF) is an important comorbidity in patients with end-stage renal disease (ESRD) undergoing dialysis that portends increased health care utilization, morbidity, and mortality in this already high-risk population. Patients with ESRD have a particularly high stroke risk, which is further compounded by AF. However, the role of anticoagulation for stroke prophylaxis in ESRD and AF is debated. The ESRD population presents a unique challenge because of the combination of elevated stroke and bleeding risks. Warfarin has been traditionally used in this population, but it is associated with significant risks of minor and major bleeding, particularly intracranial, thus leading many clinicians to forgo anticoagulation altogether. When anticoagulation is prescribed, rates of adherence and persistence are poor, leaving many patients untreated. The direct oral anticoagulants (DOACs) may offer an alternative to warfarin in ESRD patients, but these agents have not been extensively studied in this population and uncertainties regarding comparative effectiveness (versus warfarin, each other, and no treatment) remain. In this review, we discuss the current evidence on the risk and benefits of anticoagulants in this challenging population and comparisons between warfarin and DOACs, and review future directions including options for non-pharmacologic stroke prevention.

Project description:Background Benefits of patients with end-stage renal disease and atrial fibrillation undergoing peritoneal dialysis (PD) or hemodialysis are unknown. Methods and Results Patients undergoing dialysis were retrieved from Taiwan National Health Insurance Research Database during 2001 to 2013 and separated into PD or hemodialysis. Primary outcomes were ischemic stroke/systemic embolism, major bleeding, and intracranial hemorrhage (ICH). An inverse probability of treatment weighting based on propensity score was used to reduce the confounding. The risk of outcomes between PD and hemodialysis was compared using Cox proportional hazard model for fatal outcomes or Fine and Gray subdistribution hazard model which considered death a competing risk, respectively. A total of 7916 patients with end-stage renal disease with atrial fibrillation undergoing PD or hemodialysis during 2001 to 2013 were identified. After exclusion criteria, 363 patients receiving PD and 5302 patients receiving hemodialysis were analyzed. At 1-year follow-up, the risk of ICH was significantly lower in the PD group compared with the hemodialysis group (0.2% versus 0.9%; subdistribution hazard ratio [SHR], 0.31; 95% CI, 0.17-0.57). At 3-year follow-up, the risks of major bleeding and ICH were significantly lower in the PD group compared with the hemodialysis group (major bleeding: 1.8% versus 3.2%; SHR, 0.68; 95% CI, 0.53-0.87; ICH: 0.5% versus 2%; SHR, 0.32; 95% CI, 0.21-0.48). At 5-year follow-up, ischemic stroke/systemic embolism, major bleeding, and ICH were significantly lower in the PD group compared with the hemodialysis group (ischemic stroke/systemic embolism: 12.4% versus 17.7%, SHR, 0.87; 95% CI, 0.79-0.96; major bleeding: 2.6% versus 4.1%; SHR, 0.79; 95% CI, 0.64-0.97; ICH: 0.5% versus 2.6%; SHR, 0.25; 95% CI, 0.17-0.37). Conclusions In patients with end-stage renal disease and atrial fibrillation, dialytic modalities by PD or hemodialysis impacted these patients differently. There were overall reduced ischemic stroke/systemic embolism, major bleeding, and ICH at 5-year follow-up in patients undergoing PD compared with hemodialysis.
