Relation of Race, Apparent Disability, and Stroke Risk With Warfarin Prescribing for Atrial Fibrillation in Patients Receiving Maintenance Hemodialysis
We examined patterns of warfarin use, and associated factors, after AF diagnosis. This retrospective cohort analysis studied US Medicare patients receiving maintenance dialysis January 1, 2008-June 30, 2010. Demographics, comorbidity, and a durable medical equipment claims-based disability proxy score predicted warfarin prescription after AF diagnosis. The analysis included 8964 patients with non-valvular AF.

Comparison of Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement in Patients with Chronic Kidney Disease
There are few data comparing outcomes of transcatheter aortic valve implantation (TAVI) vs. surgical aortic valve replacement (SAVR) in patients with chronic kidney disease (CKD). In this retrospective cohort study using the National Inpatient Sample 2011 – 2014, we included a total of 2820 TAVI and 4054 SAVR procedures, representative of 14,039 TAVI and 19,835 SAVR procedures nationally. Co-primary outcomes were in-hospital mortality, acute kidney injury (AKI), dialysis-requiring AKI, and post-operative stroke.

Psoas Muscle Area as a Predictor of Outcomes in Trans-Catheter Aortic Valve Implantation
Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty prior to surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution between 2011 2014. Preoperative computed tomography scans were used to measure PMA, which then was indexed to body surface area. Outcomes evaluated included: 1) early poor outcome (30 day mortality, stroke, dialysis, and prolonged ventilation), 2) one year mortality and 3) high reso...

Meta-Analysis of Anticoagulation Use, Stroke, Thromboembolism, Bleeding and Mortality in Patients with Atrial Fibrillation on Dialysis
Atrial fibrillation (AF) is common in patients on dialysis. While randomized trials of anticoagulation for AF have demonstrated striking reductions in stroke, these trials did not recruit dialysis patients. We thus undertook this systematic review and meta-analysis of observational studies. Electronic databases were searched for studies including AF patients on dialysis that reported observational associations of anticoagulation use. Twenty-one studies involving 530,031 individuals and 31,611 AF patients on dialysis were identified.

Atrial fibrillation (AF) is common in patients on dialysis. Although randomized trials of anticoagulation for AF have demonstrated striking reductions in stroke, these trials did not recruit patients on dialysis. We thus undertook this systematic review and meta-analysis of observational studies including patients with AF on dialysis that reported associations of anticoagulation use. Twenty studies involving 529,741 subjects and 31,321 patients with AF on dialysis were identified. Anticoagulation was associated with a 45% (95% CI 13% to 88%) increased risk of any stroke, reflecting a nonsignificant 13% (95% CI −4% to 34...
