Effect of Race on Outcomes (Stroke and Death) in patients > 65 Years of Age with Atrial Fibrillation
Atrial fibrillation (AF) is associated with stroke and death. We sought to determine whether there are any racial differences in the outcomes of death and stroke in patients with AF. We used Medicare administrative data from January 1, 2010 to December 31, 2011 to identify 517,941 patients with newly diagnosed AF. Of these, 452,986 patients (87%) were non-Hispanic white, 36,425 (7%) were black and 28,530 (6%) were Hispanic. The association between race and outcomes of death and stroke were measured using Cox proportional hazard models.

Abstract 304: Developing a Patient Registry for Atrial Fibrillation to Improve The Quality of Stroke Prevention in a Safety Net Institution Session Title: Poster Session III
Conclusions: A baseline assessment of stroke prophylaxis among atrial fibrillation patients in a safety net health system demonstrates nonguideline-concordant anticoagulation use among low-risk patients and suboptimal anticoagulation use among high-risk patients, patterns that could not be explained by HAS-BLED score.

Sex-Specific Comparative Effectiveness of Oral Anticoagulants in Elderly Patients With Newly Diagnosed Atrial Fibrillation Original Articles
Conclusions— The reduced risk of ischemic stroke in patients taking rivaroxaban, compared with dabigatran and warfarin, seems to be limited to men, whereas the higher risk of bleeding seems to be limited to women.

Comparison of Oral Anticoagulant Use and Stroke Risk among Older Adults Newly-Diagnosed Atrial Fibrillation Living in Urban-vs-Rural Areas
We aimed to assess the association between urban/rural residence and the risk of ischemic stroke in individuals with newly diagnosed atrial fibrillation (AF), and to quantify the role of oral anticoagulation (OAC) initiation in the variation in stroke risk between urban and rural residents with AF. Using 5% random samples of Medicare claims, we identified fee-for-service beneficiaries who were diagnosed with AF between January 2014 and December 2015. Beneficiaries were followed for 1 year since their AF diagnosis, and were categorized according to their initiation of OAC within the year.

Stroke Rounds: Fewer Strokes in High-Risk Patients
(MedPage Today) -- Ischemic stroke rates dropped as warfarin use increased among Medicare beneficiaries over a 19-year period -- even among groups that have not been well represented in clinical trials, including the elderly, women, and blacks, researchers found.

Cost Effectiveness of Percutaneous Closure Versus Medical Therapy for Cryptogenic Stroke in Patients With a Patent Foramen Ovale
In patients with patent foramen ovales (PFOs) and cryptogenic stroke, observational studies have demonstrated reductions in recurrent neurologic events with transcatheter PFO closure compared with medical therapy. Randomized controlled trials and meta-analyses have shown a trend toward benefit with device closure. The cost-effectiveness of PFO closure has not been described. Therefore, a detailed cost analysis was performed using pooled weighted outcome and complication rates from published randomized controlled trials, Medicare cost tables, and wholesale medication prices.

Effectiveness and Safety of Direct Oral Anticoagulants and Warfarin, Stratified by Stroke Risk in Patients with Atrial Fibrillation
The objective of the study was to examine how the comparative effectiveness and safety of direct oral anticoagulants (DOACs) and warfarin differ across subgroups of atrial fibrillation (AF) patients defined by stroke risk (CHA2DS2-VASc score ≤3, 4-5, ≥6). Using claims data from a 5% random sample of Medicare beneficiaries, we identified patients newly diagnosed with AF in 2013-2014 who initiated warfarin (n=12,354), apixaban (n=2,358), dabigatran (n=1,415) or rivaroxaban (n=5,139), and categorized them according to their CHA2DS2-VAS c score (≤3, 4-5, ≥6).

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.

Implementation of Supervised Exercise Therapy for Patients With Symptomatic Peripheral Artery Disease: A Science Advisory From the American Heart Association.
sing; Council on Epidemiology and Prevention; and Council on Lifestyle and Cardiometabolic Health Abstract Patients with lower-extremity peripheral artery disease (PAD) have greater functional impairment, faster functional decline, increased rates of mobility loss, and poorer quality of life than people without PAD. Supervised exercise therapy (SET) improves walking ability, overall functional status, and health-related quality of life in patients with symptomatic PAD. In 2017, the Centers for Medicare & Medicaid Services released a National Coverage Determination (CAG-00449N) for SET programs for patients wit...

Abstract 274: Prevalence of undiagnosed non-valvular atrial fibrillation in the United States Session Title: Poster Session II
Conclusions: Among elderly and working adult U.S. populations, a substantial proportion of individuals with undiagnosed AF have moderate to high risk of stroke. Screening for AF could favorably impact the disease burden.

Abstract 169: The Role Of Clinical Prediction Factors On Anticoagulant Selection In Atrial Fibrillation Session Title: Poster Session I
Conclusions: Despite controlling for other patient characteristics, bleeding risk was strongly associated with the selection of a specific anticoagulant. However, the extent of selection explained by predictions of treatment harm was minimal. Providers appear to base anticoagulant selection on factors other than predictions of treatment benefit, which has implications for studying the anticoagulants’ comparative effectiveness.

Outcomes Associated with Apixaban Use in End-Stage Kidney Disease Patients with Atrial Fibrillation in the United States.
Conclusions -Among ESKD patients with AF on dialysis, apixaban use may be associated with lower risk of major bleeding compared with warfarin, with a standard 5 mg twice a day dose also associated with reductions in thromboembolic and mortality risk.
