Impact of race and ethnicity on the rhythm control of newly diagnosed atrial fibrillation: Insights from the Get With the Guidelines Atrial Fibrillation Registry. Heart Rhythm 2024:S1547-5271(24)03544-6. [PMID: 39515503 DOI: 10.1016/j.hrthm.2024.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2024] [Revised: 10/30/2024] [Accepted: 11/01/2024] [Indexed: 11/16/2024]
Abstract
BACKGROUND An early rhythm control strategy is the preferred management for patients newly diagnosed with atrial fibrillation (AF). A rhythm control strategy, however, has been historically underused for patients from underrepresented racial and ethnic groups (UREGs). OBJECTIVE We aimed to determine whether disparities in rhythm control are present at the initial diagnosis with AF. METHODS We used the Get With the Guidelines (GWTG)-Atrial Fibrillation registry to compare the use of a rhythm control strategy among patients with different racial and ethnic backgrounds hospitalized with a new diagnosis of AF from January 2013 through December 2023. RESULTS Among 21,567 patients hospitalized for newly detected AF across 249 hospitals, 17,659 patients (81.9%) identified as non-Hispanic White (NHW), 1,860 patients (8.6%) identified as Black, 1,232 patients (5.7%) identified as Hispanic, and 255 patients (1.2%) identified as Asian. After adjusting for age, sex, and year of presentation, NHW patients were more likely to receive rhythm control (odds ratio [OR], 1.19 [1.07, 1.33], P = .0013) compared with non-White patients at the time of initial diagnosis with AF. Black patients were less likely to receive rhythm control compared with all other racial and ethnic groups (OR, 0.80 [0.71, 0.91], P = .0005). These differences persisted after fully adjusting for demographic characteristics, clinical variables, hospital characteristics, and socioeconomic factors. CONCLUSIONS Differences in rhythm management exist amongst patients from different racial and ethnic groups. Efforts to mitigate disparities in AF management should include an emphasis on rhythm control at the time of initial diagnosis.

Abstract
Importance Racial and ethnic disparities exist in anticoagulation therapy for atrial fibrillation (AF). Whether medical center racial and ethnic composition is associated with these disparities is unclear. Objective To determine whether medical center racial and ethnic composition is associated with overall anticoagulation and disparities in anticoagulation for AF. Design, Setting, and Participants Retrospective cohort study of Black, White, and Hispanic patients with incident AF from 2018 to 2021 at 140 Veterans Health Administration medical centers (VAMCs). Data were analyzed from March to November 2023. Exposure VAMC racial and ethnic composition, defined as the proportion of patients from minoritized racial and ethnic groups treated at a VAMC, categorized into quartiles. VAMCs in quartile 1 (Q1) had the lowest percentage of patients from minoritized groups (ie, the reference group). Main Outcomes and Measures The odds of initiating any anticoagulant, direct-acting oral anticoagulant (DOAC), or warfarin therapy within 90 days of an index AF diagnosis, adjusting for sociodemographics, medical comorbidities, and facility factors. Results The cohort comprised 89 791 patients with a mean (SD) age of 73.0 (10.1) years; 87 647 (97.6%) were male, 9063 (10.1%) were Black, 3355 (3.7%) were Hispanic, and 77 373 (86.2%) were White. Overall, 64 770 individuals (72.1%) initiated any anticoagulant, 60 362 (67.2%) initiated DOAC therapy, and 4408 (4.9%) initiated warfarin. Compared with White patients, Black and Hispanic patients had lower rates of any anticoagulant and DOAC therapy initiation but higher rates of warfarin initiation across all quartiles of VAMC racial and ethnic composition. Any anticoagulant therapy initiation was lower in Q4 than Q1 (69.8% vs 74.9%; adjusted odds ratio [aOR], 0.80; 95% CI, 0.69-0.92; P < .001). DOAC and warfarin initiation were also lower in Q4 than in Q1 (DOAC, 69.4% vs 65.3%; aOR, 0.85; 95% CI, 0.74-0.97; P < .001; warfarin, 5.4% vs 4.5%; aOR, 0.82; 95% CI, 0.67-1.00; P < .001). In adjusted models, patients in Q4 were significantly less likely to initiate any anticoagulant therapy than those in Q1 (aOR, 0.88; 95% CI, 0.78-0.99). Patients in Q3 (aOR, 0.75; 95% CI, 0.60-0.93) and Q4 (aOR, 0.69; 95% CI, 0.55-0.87) were significantly less likely to initiate warfarin therapy than those in Q1. There was no significant difference in the adjusted odds of initiating DOAC therapy across racial and ethnic composition quartiles. Although significant Black-White and Hispanic-White differences in initiation of any anticoagulant, DOAC, and warfarin therapy were observed, interactions between patient race and ethnicity and VAMC racial composition were not significant. Conclusions and Relevance In a national cohort of VA patients with AF, initiation of any anticoagulant and warfarin, but not DOAC therapy, was lower in VAMCs serving more minoritized patients.

Abstract
BACKGROUND Landmark clinical trials have expended the indications for the direct oral anticoagulants (DOACs), but contemporary data on usage and expenditure patterns are lacking. OBJECTIVE This study aimed to assess annual trends in oral anticoagulant (OAC) utilization and expenditure across the United States (US) from 2014 to 2020. METHODS We utilized the Medical Expenditure Panel Survey (MEPS) to study the trends of use and expenditures of warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban between 2014 and 2020 in the US. Survey respondents reported OAC use within the past year, which was verified against pharmacy records. Payment information was obtained from the respondent's pharmacy and was categorized as third-party or self/out-of-pocket. Potential indications and medical conditions of interest for OAC therapy were identified from respondent-reported medical conditions. We estimated the national number of OAC users and total expenditures across age, sex, race, ethnicity, insurance, and medical condition subgroups. Trends of OAC users' characteristics, expenditure, and number of prescriptions were evaluated using the Mann-Kendall test for trends. RESULTS Between 2014 and 2020, the number of warfarin users decreased from 3.8 million (70% of all OAC users) to 2.2 million (p = 0.007) [29% of all OAC users], while the number of DOAC users increased from 1.6 million (30% of all OAC users) to 5.4 million (p = 0.003) [70% of all OAC users]. The total expenditure of OACs in the US increased from $3.4 billion in 2014 to $17.8 billion in 2020 (p = 0.003), which was driven by the increase in DOAC expenditures (p = 0.003). CONCLUSIONS DOACs have replaced warfarin as the preferred OAC in the US. The increased costs associated with DOAC use may decline when generic formulations are approved.

Abstract
BACKGROUND The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

The Neurosurgeon's Dilemma-Do Antiplatelet/Anticoagulant Medications Increase the Risk of Catheter-Associated Hemorrhage in External Ventricular Drain Placement? World Neurosurg 2024; 182:e611-e623.

Abstract
OBJECTIVE External ventricular drain (EVD) placement is a common neurosurgical procedure that can be performed at bedside. A frequent complication following EVD placement is catheter-associated hemorrhage (CAH). The hemorrhage itself is rarely clinically significant but may be complicated in patients taking anticoagulant or antiplatelet (AC/AP) medications. METHODS A total of 757 patients were who underwent EVD placement at bedside were included as part of a retrospective study at a large academic medical center. Demographic factors, use of AC/AP therapies, and several other clinical variables were recorded and assessed in univariate and multivariate regression analysis for association with CAH and mortality. RESULTS One hundred (13.2%) patients experienced CAH within 24 hours of the procedure. After univariate analysis, in 2 tandem-run multivariate regression analyses after stepwise variable selection, use of 2 or more AC/AP agents (odds ratio [OR] = 2.362, P = 0.020) and dual antiplatelet therapy with aspirin and clopidogrel (OR = 3.72, P = 0.009) were significantly associated with CAH. Use of noncoated catheters was a protective factor against CAH compared to use of antibiotic-coated catheters (OR = 0.55, P = 0.019). Multivariate analysis showed age, multiagent therapy, and thrombocytopenia were significantly associated with increased mortality. CONCLUSIONS There was increased risk of CAH after EVD placement in patients taking more than one AC/AP agent regardless of presenting pathology. In particular, use of aspirin and clopidogrel combined was associated with significantly higher odds of CAH, although it was not associated with higher mortality. In addition, there appears to be an association between use of antibiotic-coated catheters and CAH across univariate and multivariate analysis.

Abstract
Stroke is a leading cause of death and disability in the United States and worldwide, necessitating comprehensive efforts to optimize stroke risk factor management. Health disparities in stroke incidence, prevalence, and risk factor management persist among various race/ethnic, geographic, and socioeconomic populations and negatively impact stroke outcomes. This review highlights existing literature and guidelines for stroke risk factor management, emphasizing health disparities among certain populations. Moreover, stroke risk factors for special groups, including the young, the very elderly, and pregnant/peripartum women are outlined. Strategies for stroke risk factor improvement at every level of the health care system are discussed, from the individual patient to providers, health care systems, and policymakers. Improving stroke risk factor management in the context of the social determinants of health, and with the goal of eliminating inequities and disparities in stroke prevention strategies, are critical steps to reducing the burden of stroke and equitably improving public health.

Abstract
Introduction Anticoagulation treatment is routinely underused in patients with atrial fibrillation (AF), particularly in settings with limited resources. The current study is aimed at evaluating the appropriateness of oral anticoagulation treatment among AF patients at the Yekatit 12 Hospital Medical College (Y12HMC), Addis Ababa, Ethiopia. Methods Institutional-based retrospective cross-sectional study conducted in Y12HMC from November 2019 to March 2020. During the study period, 256 patients' medical records were found; 231 of them met the eligibility criteria and were included in the study. The data were analyzed using SPSS version 25, descriptive statistics were used to summarize the data, and binary logistic regression was performed to identify predictors of inappropriate anticoagulation management. Results The majority of study participants were males (55.8%), and over half of them (57.6%) had a nonvalvular type of AF. The majority of patients (61.9%) were receiving anticoagulant treatment, and of them, warfarin was prescribed to most of the study subjects (71.3%). Nearly half (47.6%) of the study participants had inappropriate anticoagulation treatment; among these, the majority of them (69.1%) were from a valvular type of AF. Patients with a valvular type of AF and having the diagnosis of congestive heart disease as comorbidity showed a statistically significant association towards inappropriate anticoagulation management. Conclusion According to the study, a significant portion of AF patients received inappropriate anticoagulant treatment, which may play a significant role for the increased risk of stroke in these groups of patients. All of the inappropriate cases were due to failure to start anticoagulant treatment.

Abstract
Introduction Breakthrough acute ischemic stroke (AIS) in patients with known, nonvalvular Atrial Fibrillation (AF), on Direct Oral Anticoagulants (DOAC), is an ongoing clinical conundrum. Switching anticoagulants was shown to be ineffective in preventing recurrent AIS. Systematic, patient-level chart review of so-called "DOAC failures" may offer insight into this phenomenon. Methods We conducted an IRB-approved, 6-year, retrospective study of AIS admissions, already prescribed DOAC for known AF. We sought plausible, alternative reasons for the AIS using a novel classification schema, CLAMP: C for Compliance concerns, L for Lacunes (small-vessel disease), A for Arteriopathy (atherosclerosis, web, or vasculitis), M for Malignancy, and P for Patent Foramen Ovale (PFO). These categories were labeled as DOAC "Pseudo-failures." Conversely, absence of CLAMP variables were labeled as DOAC "Crypto-failures" conceivably from AF itself ("atriopathy") or pharmacokinetic/pharmacogenomic dysfunction (ie, altered DOAC absorption, clearance, metabolism, or genetic polymorphisms). Forward logistic regression analysis was performed on prespecified DOAC subgroups. Results Of 4890 AIS admissions, 606 had AF, and 87 were previously prescribed DOAC (14.4% overall DOAC failure rate, 2.4% annualized over 6 years). Pseudo-failures comprised 77%: Compliance concerns (48.9%), Lacunes (5.7%), Arteriopathy (17.0%), Malignancy (26.1%), and PFO (2.3%). Crypto-failures comprised 23%, had lower CHADSVASc scores (AOR = .65, P = .013), and occurred more with rivaroxaban (41%) than apixaban (16%) or dabigatran (5.6%). Conclusion In AIS patients with known AF, DOAC Pseudo-failures, with identified alternate etiologies, are 3 times more likely than DOAC Crypto-failures. The CLAMP schema represents a novel approach to diagnostic classification and therapeutic adjustments in patients already prescribed DOAC for AF.

Abstract
BACKGROUND Patients with atrial fibrillation are characterized by great clinical heterogeneity and complexity. The usual classifications may not adequately characterize this population. Data-driven cluster analysis reveals different possible patient classifications. AIMS To identify different clusters of patients with atrial fibrillation who share similar clinical phenotypes, and to evaluate the association between identified clusters and clinical outcomes, using cluster analysis. METHODS An agglomerative hierarchical cluster analysis was performed in non-anticoagulated patients from the Loire Valley Atrial Fibrillation cohort. Associations between clusters and a composite outcome comprising stroke/systemic embolism/death and all-cause death, stroke and major bleeding were evaluated using Cox regression analyses. RESULTS The study included 3434 non-anticoagulated patients with atrial fibrillation (mean age 70.3±17 years; 42.8% female). Three clusters were identified: cluster 1 was composed of younger patients, with a low prevalence of co-morbidities; cluster 2 included old patients with permanent atrial fibrillation, cardiac pathologies and a high burden of cardiovascular co-morbidities; cluster 3 identified old female patients with a high burden of cardiovascular co-morbidities. Compared with cluster 1, clusters 2 and 3 were independently associated with an increased risk of the composite outcome (hazard ratio 2.85, 95% confidence interval 1.32-6.16 and hazard ratio 1.52, 95% confidence interval 1.09-2.11, respectively) and all-cause death (hazard ratio 3.54, 95% confidence interval 1.49-8.43 and hazard ratio 1.88, 95% confidence interval 1.26-2.79, respectively). Cluster 3 was independently associated with an increased risk of major bleeding (hazard ratio 1.72, 95% confidence interval 1.06-2.78). CONCLUSION Cluster analysis identified three statistically driven groups of patients with atrial fibrillation, with distinct phenotype characteristics and associated with different risks for major clinical adverse events.

Race, ethnicity, sex, and socioeconomic disparities in anticoagulation for atrial fibrillation: A narrative review of contemporary literature. J Natl Med Assoc 2023; 115:290-297. [PMID: 36882341 PMCID: PMC11333120 DOI: 10.1016/j.jnma.2023.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 01/27/2023] [Accepted: 02/10/2023] [Indexed: 03/07/2023]
Abstract
Atrial fibrillation (AF) is the most prevalent arrhythmia in the United States and is responsible for 1 in 7 ischemic strokes. While anticoagulation is effective at preventing strokes, prior work has highlighted significant disparities in anticoagulation prescribing. Furthermore, racial, ethnic, sex, and socioeconomic disparities in AF outcomes have been described. As such, we aimed to review recent data on disparities with respect to anticoagulation for AF published between January 2018 and February 2021. The search string consisted of 7 phrases that combined AF, anticoagulation, and disparities involving sex, race, ethnicity, income, socioeconomic status (SES), and access to care and identified 13 relevant articles. The aggregate data demonstrated that Black patients were less likely to be prescribed anticoagulation than patients of other racial/ethnic groups. Additionally, Black patients were more likely to be prescribed warfarin instead of direct oral anticoagulants (DOACs) despite evidence that DOACs are safer and better tolerated. Lower-income patients and patients with less education were also less likely to receive DOACs. Some studies found that women were less likely to be anticoagulated than men even when their estimated stroke risk was higher, although other studies did not show sex-based differences. Building upon prior work, our study demonstrates that racial and ethnic disparities have persisted in the management of AF. Additionally, we our work highlights that there are significant disparities in anticoagulation management for AF associated with sex, income, and education. More work is needed to identify mechanisms for these disparities and identify potential solutions to achieve pharmacoequity.

Abstract
Importance Race-based disparities in atrial fibrillation (AF) outcomes are well-documented, but few studies have investigated individuals' experiences of living with the condition, particularly among Black individuals. Objective We aimed to identify common themes and challenges experienced by individuals of Black race with AF. Design A tailored, qualitative script was developed to assess the perspectives of participants in focus groups. Setting Virtual focus groups. Participants Three focus groups of 4-6 participants (16 participants total) were recruited from the racial/ethnic minority participants in the Mobile Relational Agent to Enhance Atrial Fibrillation Self-care Trial. Main outcomes and measures Focus group transcripts were inductively coded to identify common themes. Results Nearly all participants self-identified as Black race (n = 15, 93.8 %). Participants were mostly male (62.5 %) with mean age of 67 (range 40-78) years. Three themes were identified. First, participants described physical and mental burdens associated with having AF. Second, participants described AF as being a condition that is difficult to manage. Lastly, participants identified key tenets to support self-management of AF (self-education, community support, and patient-provider relationships). Conclusions and relevance Participants reported AF is unpredictable and challenging to manage, and that social and community supports are essential. The social and behavioral themes identified in this qualitative research highlight the need for tailored clinical strategies for AF self-management which incorporate individuals' social contexts.

Abstract
Racial and ethnic disparities in health care are well documented, although often underappreciated. In the setting of atrial fibrillation, stroke risk and severity may be higher in underrepresented ethnic populations. Additionally, the risk of bleeding is not uniform, and pharmacogenetics play an important role in anticoagulant therapy. In this narrative review, we discuss the complex issues surrounding stroke prevention in underrepresented ethnic groups with atrial fibrillation.

Abstract
Background Direct oral anticoagulants (DOACs) are a first-line anticoagulant therapy for eligible patients with atrial fibrillation. Prescribing differences in the Military Health System have not yet been assessed. Methods We conducted a retrospective cross-sectional study using administrative claims data from the Military Health System Data Repository from fiscal years 2018-2019. We identified TRICARE Prime and Prime Plus patients between the ages of 18 and 64 with a diagnosis of atrial fibrillation and a CHA2DS2-VASc score of ≥2. Descriptive statistics and odds of receiving DOACs by gender, age, race, and socioeconomic status were calculated. Results A total of 5289 TRICARE Prime and Prime Plus patients within the Military Health System who carried a diagnosis of atrial fibrillation and a CHA2DS2-VASc ≥2 were identified. Of all patients, 2373 (40.71 %) were prescribed a DOAC whereas 287 (4.92 %) were prescribed warfarin within 90 days of diagnosis of atrial fibrillation. Black patients were significantly less likely to be prescribed a DOAC compared to White patients (adjusted odds ratio [aOR], 0.82; 95 % CI 0.68-0.99), as were females compared to males (aOR, 0.64; 95 % CI 0.52-0.79). Senior officers were significantly more likely to be prescribed a DOAC compared to senior enlisted service members (aOR, 0.64; 95 % CI 0.52-0.79). Conclusions Our study shows that differences exist within the Military Health System in the prescription of DOACs for atrial fibrillation by race, gender, and socio-economic status. These differences cannot be explained by differences in access to insurance or cost of medications.

Abstract
Telehealth has seen rapid expansion into chronic care management in the past 3 years because of the COVID-19 pandemic. Telehealth for acute care management has expanded access to equitable stroke care to many patients over the past two decades, but there is limited evidence for its benefit for addressing disparities in the chronic care of patients living with stroke. In this review, we discuss advantages and disadvantages of telehealth use for the outpatient management of stroke survivors. Further, we explore opportunities and potential barriers for telehealth in addressing disparities in stroke outcomes related to various social determinants of health. We discuss two ongoing large randomized trials that are utilizing telehealth and telemonitoring for management of blood pressure in diverse patient populations. Finally, we discuss strategies to address barriers to telehealth use in patients with stroke and in populations with adverse social determinants of health.

Abstract
Importance Oral anticoagulation (OAC) is underprescribed in underrepresented racial and ethnic group individuals with atrial fibrillation (AF). Little is known of how differential OAC prescribing relates to inequities in AF outcomes. Objective To compare OAC use at discharge and AF-related outcomes by race and ethnicity in the Get With The Guidelines-Atrial Fibrillation (GWTG-AFIB) registry. Design, Setting, and Participants This retrospective cohort analysis used data from the GWTG-AFIB registry, a national quality improvement initiative for hospitalized patients with AF. All registry patients hospitalized with AF from 2014 to 2020 were included in the study. Data were analyzed from November 2021 to July 2022. Exposures Self-reported race and ethnicity assessed in GWTG-AFIB registry. Main Outcomes and Measures The primary outcome was prescription of direct-acting OAC (DOAC) or warfarin at discharge. Secondary outcomes included cumulative 1-year incidence of ischemic stroke, major bleeding, and mortality postdischarge. Outcomes adjusted for patient demographic, clinical, and socioeconomic characteristics as well as hospital factors. Results Among 69 553 patients hospitalized with AF from 159 sites between 2014 and 2020, 863 (1.2%) were Asian, 5062 (7.3%) were Black, 4058 (5.8%) were Hispanic, and 59 570 (85.6%) were White. Overall, 34 113 (49.1%) were women; the median (IQR) age was 72 (63-80) years, and the median (IQR) CHA2DS2-VASc score (calculated as congestive heart failure, hypertension, age 75 years and older, diabetes, stroke or transient ischemic attack, vascular disease, age 65 to 74 years, and sex category) was 4 (2-5). At discharge, 56 385 patients (81.1%) were prescribed OAC therapy, including 41 760 (74.1%) receiving DOAC. OAC prescription at discharge was lowest in Hispanic patients (3010 [74.2%]), followed by Black patients (3935 [77.7%]) Asian patients (691 [80.1%]), and White patients (48 749 [81.8%]). Black patients were less likely than White patients to be discharged while taking any anticoagulant (adjusted odds ratio, 0.75; 95% CI, 0.68-0.84) and DOACs (adjusted odds ratio, 0.73; 95% CI, 0.65-0.82). In 16 307 individuals with 1-year follow up data, bleeding risks (adjusted hazard ratio [aHR], 2.08; 95% CI, 1.53-2.83), stroke risks (aHR, 2.07; 95% CI, 1.34-3.20), and mortality risks (aHR, 1.22; 95% CI, 1.02-1.47) were higher in Black patients than White patients. Hispanic patients had higher stroke risk (aHR, 2.02; 95% CI, 1.38-2.95) than White patients. Conclusions and Relevance In a national registry of hospitalized patients with AF, compared with White patients, Black patients were less likely to be discharged while taking anticoagulant therapy and DOACs in particular. Black and Hispanic patients had higher risk of stroke compared with White patients; Black patients had a higher risk of bleeding and mortality. There is an urgent need for interventions to achieve pharmacoequity in guideline-directed AF management to improve overall outcomes.

Abstract
BACKGROUND: Atrial fibrillation (AF) imposes substantial health care and economic burden on health care systems and patients. Previous studies failed to examine health care resource utilization (HCRU) and costs among patients with incident AF and potential disparity with regard to geographic location. OBJECTIVES: To examine HCRU and costs among patients with incident AF compared with patients without AF and examine whether a geographic disparity exists. METHODS: This was a retrospective cohort study. We selected patients with AF and patients without AF from IBM/Watson MarketScan Research Databases 2014-2019. HCRU and costs were collected 12 months following an AF index date. We used 2-part models with bootstrapping to obtain the marginal estimates and CIs. Rural status was identified based on Metropolitan Statistical Area. We adjusted for age, sex, plan type, US region, and comorbidities. RESULTS: Among 156,732 patients with AF and 3,398,490 patients without AF, patients with AF had 9.04 (95% CI = 8.96-9.12) more outpatient visits, 0.82 (95% CI = 0.81-0.83) more emergency department (ED) visits, 0.33 (95% CI = 0.33-0.34) more inpatient admission, and $15,095 (95% CI = 14,871-15,324) higher total costs, compared with patients without AF. Among patients with AF, rural patients had 1.99 fewer (95% CI = -2.26 to -1.71) outpatient visits and 0.05 (95% CI = 0.02-0.08) more ED visits than urban patients. Overall, rural patients with AF had decreased total costs compared with urban patients (mean = $751; 95% CI = -1,227 to -228). CONCLUSIONS: Incident AF was associated with substantial burden of health care resources and an economic burden, and the burden was not equally distributed across patients in urban vs rural settings. DISCLOSURES: Dr Hansen reports grants from the National Science Foundation during the conduct of the study.

Abstract
Objective To explore factors associated with anticoagulation (AC) initiation after atrial fibrillation (AF) diagnosis. Design Retrospective cohort study. Setting Urban medical center. Patients Adults with emergency department (ED) diagnosis of new onset AF from 1/1/2017-1/1/2020 discharged home. Methods We compared patients initiated on AC, our primary outcome, to those not initiated on AC. Stroke, major bleeding, and AC initiation within 1 year of visit were secondary outcomes. We hypothesized that minority race and non-English language preference are associated with failure to initiate AC. Results Of 111 patients with AF, 88 met inclusion criteria. Mean age was 65 (SD 15); 47 (53%) were women. 49 (56%) patients were initiated on AC. Age (61 vs 68 years; P=.02), non-English language (28% vs 10%; P=.03), leaving ED against medical advice (AMA) (36% vs 14%; P=.04), and CHA2DS2-VASc score of 1 (41% vs 6%; P<=.001) were associated with no AC initiation. There were no associations between patient-reported race/ethnicity and AC. Cardiology consultation (83.67% vs 30.78%; P<.0001) and higher median CHA2DS2-VASc score (3[2-4]) vs. 2[1-4]; P=.047) were associated with AC. Of 73 patients with follow-up data at 1 year, 2 (8%) not initiated on AC had strokes, 2 (4%) initiated on AC had major bleeds, and 15 (62.5%) not initiated on AC in the ED subsequently were initiated on AC. Conclusion More than half of ED patients with new AF eligible for AC were initiated on it. Work to improve AC utilization among patients with new AF who left AMA from ED and those who prefer to communicate in a non-English language may be warranted.

Abstract
BACKGROUND A growing body of literature now exists examining associations between social determinants of health (SDOH) and adverse outcomes in patients with atrial fibrillation; however, little is available on anticoagulant prescriptions and the impact of SDOH. PURPOSE Evaluate the impact of SDOH on anticoagulant prescriptions in patients with atrial fibrillation. DATA SOURCES Medline and Embase databases up to January 2021. STUDY SELECTION Noninterventional studies were included if they reported associations between at least 1 of 14 SDOH domains and anticoagulant prescription in patients with atrial fibrillation. Two investigators independently screened and collected data. DATA EXTRACTION Two investigators independently screened and collected data. DATA SYNTHESIS Meta-analyses using random-effect models evaluated associations between SDOH and receiving an anticoagulant prescription. We included 13 studies, 11 of which were included in meta-analyses that reported on the impact of 9 of the 14 SDOH included in the search. Pooled estimates indicate a 0.85 (95% confidence interval [CI]: 0.75, 0.97) lower odds of receiving anticoagulant prescriptions among Black compared to non-Black patients (reported in 6 studies); 0.42 (95% CI: 0.32, 0.55) lower odds of receiving anticoagulant prescriptions among patients with mental illness compared to those without mental illness (2 studies); and a 0.64 (95% CI: 0.42, 0.96) lower likelihood of receiving oral anticoagulant prescription among employed patients compared to unemployed patients (2 studies). LIMITATIONS SDOH lack consistent definitions and measures within the electronic health record. CONCLUSION The literature reports on only half of the SDOH domains we searched for, indicating that many SDOH are not routinely assessed. Second, social needs impact the decision to prescribe anticoagulants, confirming the need to screen for and address social needs in the clinical setting to support clinicians in providing guideline concordant care to their patients. REGISTRATION This systematic review and meta-analysis was registered with PROSPERO.

Abstract
INTRODUCTION Disparities in overall outcomes for atrial fibrillation (AF) across racial and ethnic groups have been demonstrated in prior studies. We aim to evaluate in-hospital outcomes and resource utilization across three racial/ethnic groups with AF using contemporary data. METHODS We identified patients admitted with AF in the National Inpatient Sample registry from 2015 to 2018. ICD-10-CM codes were used to identify variables of interest. The primary outcomes were in-hospital complications and resource utilization. RESULTS There were 1,250,075 AF admissions. Our sample was made up of 85.49% White, 8.12% Black, and 6.38% Hispanic patients. Black patients were younger but had a higher burden of cardiovascular comorbidities including obesity, hypertension, and chronic kidney disease. Social determinants were also less favorable in Black patients, with a higher percentage of Medicaid insurance and a high proportion of patients being in the lowest percentile for household income. Total hospital charge was highest in Hispanic patients. Despite higher rates of gastrointestinal bleed, Black patients were least likely to undergo left atrial appendage occlusion device implantation. Black and Hispanic patients were less like to undergo catheter ablation therapy. Black race was an independent predictor of mortality, stroke, mechanical ventilation, acute kidney injury, hemodynamic shock, need for vasopressor, upper GI bleed, need for blood transfusion, total hospital charges, and length of stay when compared to other groups. CONCLUSION Disparities exist in the risk of AF, and its management among racial and ethnic groups. Health care costs and inpatient outcomes disproportionately impact minorities in the United States.

Functional status at 30 and 90 days after mild ischaemic stroke. Stroke Vasc Neurol 2022; 7:svn-2021-001333.

Abstract
BACKGROUND/OBJECTIVE This study compares the global disability status of patients who had a mild ischaemic stroke at 30 and 90 days poststroke, as measured by the modified Rankin Scale (mRS), and identifies predictors of change in disability status between 30 and 90 days. METHODS The study population included 1339 patients who had a ischaemic stroke enrolled in the Mild and Rapidly Improving Stroke Study with National Institutes of Health (NIH) stroke score 0-5 and mRS measurements at 30 and 90 days. Outcomes were (1) Improvement defined as having mRS >1 at 30 days and mRS 0-1 at 90 days OR mRS >2 at 30 days and mRS 0-2 at 90 days and (2) Worsening defined as an increase of ≥2 points or a worsening from mRS of 1 at 30 days to 2 at 90 days. Demographic and clinical characteristics at hospital arrival were abstracted from medical records, and regression models were used to identify predictors of functional improvement and decline from 30 to 90 days post-stroke. Significant predictors were mutually adjusted in multivariable models that also included age and stroke severity. RESULTS Fifty-seven per cent of study participants had no change in mRS value from 30 to 90 days. Overall, there was moderate agreement in mRS between the two time points (weighted kappa=0.59 (95% CI 0.56 to 0.62)). However, worsening on the mRS was observed in 7.54% of the study population from 30 to 90 days, and 17.33% improved. Participants of older age (per year OR 1.02, 95% CI 1.00 to 1.03), greater stroke severity (per NIH Stroke Scale (NIHSS) point at admission OR 1.17, 95% CI 1.03 to 1.34), and those with no alteplase treatment (OR 1.72, 95% CI 1.11 to 2.69) were more likely to show functional decline after mutual adjustment. DISCUSSION A quarter of all mild ischaemic stroke participants exhibited functional changes between 30 and 90 days, suggesting that the 30-day outcome may insufficiently represent long-term recovery in mild stroke and longer follow-up may be clinically necessary. TRIAL REGISTRATION NUMBER NCT02072681.

Abstract
Oral anticoagulation (OAC) prevents thromboembolism yet greatly increases the risk of bleeding, inciting concern among clinicians. Current guidelines lack sufficient evidence supporting long-term OAC following successful atrial fibrillation catheter ablation (CA). A literature search was performed in PubMed, Google Scholar, Medline, and Scopus to seek out studies that compare continued and discontinued anticoagulation in post-ablation Atrial fibrillation (AF) patients. Funnel plots and Egger’s test examined potential bias. Via the random-effects model, summary odds ratios (OR) with 95% confidence intervals (CI) were calculated using RevMan (5.4) and STATA (17.0). Twenty studies, including 22 429 patients (13 505 off-OAC) were analyzed. Stratified CHA2DS2-VASc score ≥2 examining thromboembolic events (TE) favored OAC continuation (OR 1.86; 95% CI: 1.02-3.40; P = .04). Sensitivity analysis demonstrated this association was attenuated. The on-OAC arm had greater incidence of major bleeding (MB) (OR 0.16; 95% CI: 0.08-0.95; P < .00001), particularly intracranial hemorrhage (ICH) and gastrointestinal bleeding (GI); (OR 0.17; 95% CI: 0.08-0.36; P < .00001) and (OR 0.12; 95% CI: 0.04-0.32; P < .0001), respectively. Our findings support sustained anticoagulation in patients with a CHA2DS2-VASc score of ≥2. Due to reduced outcome robustness, physician discretion is still advised.

Abstract
Atrial fibrillation (AF) is the most common clinical arrhythmia, and it results in adverse outcomes and increased healthcare costs. Racial and ethnic differences in AF management, although recognized, are poorly understood. This review summarizes racial differences in AF epidemiology, genetics, clinical presentation, and management. In addition, it highlights the underrepresentation of racial and ethnic populations in AF clinical trials, especially trials focused on stroke prevention. Specific strategies are proposed for future research and initiatives that have potential to eliminate racial and ethnic differences in the care of patients with AF. Addressing racial and ethnic disparities in healthcare access, enrollment in clinical trials, resource allocation, prevention, and management will likely narrow the gaps in the care and outcomes of racial and ethnic minorities suffering from AF.

Abstract
Atrial fibrillation affects almost 60 million adults worldwide. Atrial fibrillation is associated with a high risk of cardiovascular morbidity and death as well as with social, psychological and economic burdens on patients and their families. Social determinants - such as race and ethnicity, financial resources, social support, access to health care, rurality and residential environment, local language proficiency and health literacy - have prominent roles in the evaluation, treatment and management of atrial fibrillation. Addressing the social determinants of health provides a crucial opportunity to reduce the substantial clinical and non-clinical complications associated with atrial fibrillation. In this Review, we summarize the contributions of social determinants to the patient experience and outcomes associated with this common condition. We emphasize the relevance of social determinants and their important intersection with atrial fibrillation treatment and outcomes. In closing, we identify gaps in the literature and propose future directions for the investigation of social determinants and atrial fibrillation.

Abstract
Prescribing anticoagulation therapy in very old (≥ 80-years) patients with atrial fibrillation (AF) is an emerging clinical issue, but current knowledge and recommendations are insufficient. We aimed to determine the efficacy and safety of direct oral anticoagulants (DOACs) in secondary stroke prevention in very old patients and to explore the related geriatric functional status of these patients. Three hundred fifty-three consecutive ≥ 80-year-old patients treated for transient ischemic attack (TIA) or ischemic stroke (IS) at the neurological clinic at UMC Ljubljana, who were prescribed DOACs for AF between December 2012 and May 2020, were included. Data regarding recurrent TIA/IS, major bleeds, intracranial hemorrhage (ICH) and death were collected. Data were descriptively compared with data from RCTs- including younger patients. Patients prescribed DOACs between January 2018 and May 2020 were contacted in December 2020, and their functional status was assessed using the Barthel index (BI). The efficacy of secondary stroke prevention with DOACs was comparable to RCTs for significantly younger patients. Major bleeds occurred more often, but most incidences were gastrointestinal, and the rate of ICH was comparable. Importantly, most patients were highly independent determined by BI. Overall, our real world results suggest that DOACs are as effective at preventing IS in secondary prevention in very old patients than in younger patients and that geriatric functional assessment could be a useful tool in the decision-making process.

Abstract
Primary care teams provide the majority of poststroke care. When optimally configured, these teams provide patient-centered care to prevent recurrent stroke, maximize function, prevent late complications, and optimize quality of life. Patient-centered primary care after stroke begins with establishing the foundation for poststroke management while engaging caregivers and family members in support of the patient. Screening for complications (eg, depression, cognitive impairment, and fall risk) and unmet needs is both a short-term and long-term component of poststroke care. Patients with ongoing functional impairments may benefit from referral to appropriate services. Ongoing care consists of managing risk factors such as high blood pressure, atrial fibrillation, diabetes, carotid stenosis, and dyslipidemia. Recommendations to reduce risk of recurrent stroke also include lifestyle modifications such as healthy diet and exercise. At the system level, primary care practices can use quality improvement strategies and available resources to enhance the delivery of evidence-based care and optimize outcomes.

Abstract
INTRODUCTION Hip fractures lead to a substantial burden of disease and mortality among the elderly. Myocardial infarction (MI) and stroke are serious and overlooked complications, and their impact on mortality and morbidity may be underestimated. We investigated; 90-day absolute risk of stroke and MI following hip fracture surgery, and ii) anamnestic risk factors associated with elevated risk of postoperative MI and stroke. METHODS All Danish patients aged ≥60 undergoing first time hip fracture surgery in 2000-2017 were identified. Outcomes were MI or stroke 90 days after surgery. We performed gender-stratified cumulative incidence functions and multivariate Cox regression models adjusted for age and comorbidities. RESULTS 124,660 patients were included. Incidence of MI was 2.2% and 1.3%, and incidence of stroke was 3.5% and 2.5%, in men and women, respectively. The most important risk factor for MI and stroke was a previous event. Hazard ratio (HR) of MI associated with previous MI was 2.43 (95% Confidence Interval (CI) 2.02-2.92) in men and 2.65 (95% CI 2.23-3.16) in women, while the HR of stroke associated with previous stroke was 4.17 (95% CI 3.73-4.67) and 3.73 (95% CI 3.43-4.08), respectively. Other risk factors of MI were; sex, age, and a history of heart failure, hypertension, peripheral artery disease or diabetes. For postoperative stroke; sex age, and atrial fibrillation were important risk factors. CONCLUSION MI and stroke after hip fractures are overlooked and serious complications. Persons with elevated risk can be identified at admission, based on their medical history.

Abstract
BACKGROUND Stroke severity can be mitigated by preceding anticoagulant administration in acute ischemic stroke patients with atrial fibrillation (AF). We investigated if such mitigative effects are different between warfarin and direct oral anticoagulants (DOACs). MATERIAL AND METHODS We collected data from a regional multicenter stroke registry. Ischemic stroke or transient ischemic attack patients with AF were included. Background characteristics, National Institutes of Health Stroke Scale (NIHSS) score on admission, lesion characteristics, and in-hospital death were analyzed according to preceding antithrombotic agents at onset. RESULTS A total of 2173 patients had AF; 628 were prescribed warfarin, 272 DOACs, 429 antiplatelets alone, and 844 no antithrombotics. The NIHSS score on admission was lowest in the DOACs group compared to the other groups. In neuroimaging analysis, small ischemic lesions were observed more frequently in the DOACs group, while large ischemic lesions were less frequent in this group. When the no antithrombotics group was used as a reference, the adjusted odds ratio for moderate to severe stroke was 0.56 (95% confidence interval, 0.40-0.78) in the DOACs group, while it was 0.98 (0.77-1.24) in the warfarin group and 0.94 (0.72-1.22) in the antiplatelets group. In-hospital mortality was lowest in the DOACs group compared to the other groups. CONCLUSION Preceding DOAC administration might mitigate the severity of stroke in AF patients more strongly than other antithrombotics, possibly leading to a better outcome in patients with stroke.

Abstract
BACKGROUND AND PURPOSE We investigated the prevalence, awareness, and control of vascular risk factors (VRFs) and the use of antithrombotic and statin agents in HCHS (Hispanic Community Health Study)/SOL (Study of Latinos) participants with self-reported history of stroke or transient ischemic attack. METHODS Sociodemographic characteristics, medications, and prevalence of different VRFs were recorded. VRF diagnoses and goals were based on the recommendations of professional organizations. Factors associated with optimal VRF control and use of antithrombotic and statin agents were investigated using multivariate logistic regression. RESULTS The analysis included 404 participants (39% men). The prevalences of hypertension, dyslipidemia, and diabetes were 59%, 65%, and 39%, respectively. Among those who met the diagnostic criteria for these diagnoses, the frequencies of awareness were 90%, 75%, and 83%, respectively. In participants who were aware of their VRFs, the prevalences of controlled hypertension, dyslipidemia, and diabetes were 46%, 32%, and 54%. Approximately 46% of the participants were on antithrombotics, 39% on statins, and 26% on both. Only 38% of those with atrial fibrillation received anticoagulation. In multivariate analyses adjusted for baseline sociodemographic characteristics, older age was associated with uncontrolled hypertension and diabetes. Residing in the United States for ≥10 years and born in the United States were associated with uncontrolled diabetes, female sex with uncontrolled dyslipidemia, and lack of health insurance with decreased use of statins and hyperlipidemia. CONCLUSIONS Hispanic/Latino adults in the United States have high prevalence and awareness of VRFs but low adherence to secondary stroke prevention strategies. Older adults, women, and uninsured people are vulnerable groups that may benefit from targeted interventions. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02060344.

Abstract
PURPOSE OF REVIEW Direct oral anticoagulants (DOAC) are crucial for the prevention of thromboembolic events in patients with nonvalvular atrial fibrillation. Drug adherence by the patient but also adherence to guidelines by the physician are suboptimal. This review highlights aspects of DOAC treatment during the coronavirus disease 2019 (COVID-19) pandemic and selected challenging scenarios. RECENT FINDINGS For patients with a newly diagnosed indication for oral anticoagulation, a new interim clinical guidance recommends starting DOAC instead of vitamin K antagonists if DOAC are not contraindicated. The goal is to reduce the potential exposure of patients to severe acute respiratory syndrome coronavirus during the routine coagulation monitoring visits. As COVID-19 can lead to kidney failure, we discuss the challenges of DOAC dosing in kidney failures. Finally, we discuss two common challenges - when to start a DOAC after an ischemic stroke linked to atrial fibrillation, and whether cerebral microbleeds, including their count, are per se a contraindication to DOAC. SUMMARY There are still open challenges regarding DOAC treatment on the patient and physician side, both related and unrelated to the pandemic.

Abstract
BACKGROUND Several studies suggest women may be disproportionately affected by poorer stroke outcomes than men. This study aims to investigate whether women have a higher risk of all-cause mortality and recurrence after an ischemic stroke than men in a rural population in central Pennsylvania, United States. METHODS We analyzed consecutive ischemic stroke patients captured in the Geisinger NeuroScience Ischemic Stroke research database from 2004 to 2019. Kaplan-Meier (KM) estimator curves stratified by gender and age were used to plot survival probabilities and Cox Proportional Hazards Ratios were used to analyze outcomes of all-cause mortality and the composite outcome of ischemic stroke recurrence or death. Fine-Gray Competing Risk models were used for the outcome of recurrent ischemic stroke, with death as the competing risk. Two models were generated; Model 1 was adjusted by data-driven associated health factors, and Model 2 was adjusted by traditional vascular risk factors. RESULTS Among 8900 adult ischemic stroke patients [median age of 71.6 (interquartile range: 61.1-81.2) years and 48% women], women had a higher crude all-cause mortality. The KM curves demonstrated a 63.3% survival in women compared with a 65.7% survival in men (p = 0.003) at 5 years; however, the survival difference was not present after controlling for covariates, including age, atrial fibrillation or flutter, myocardial infarction, diabetes mellitus, dyslipidemia, heart failure, chronic lung diseases, rheumatic disease, chronic kidney disease, neoplasm, peripheral vascular disease, past ischemic stroke, past hemorrhagic stroke, and depression. There was no adjusted or unadjusted sex difference in terms of recurrent ischemic stroke or composite outcome. CONCLUSION Sex was not an independent risk factor for all-cause mortality and ischemic stroke recurrence in the rural population in central Pennsylvania.

Bleeding risk comparison between direct oral anticoagulants at doses approved for atrial fibrillation and aspirin: systematic review, meta-analysis and meta-regression. Eur J Intern Med 2020; 79:31-36. [PMID: 32409203 DOI: 10.1016/j.ejim.2020.05.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 04/28/2020] [Accepted: 05/01/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND A considerable proportion of patients with atrial fibrillation (AF) are still treated with aspirin despite current guidelines due to presumed favorable safety. AIM We performed a systematic review and meta-analysis of bleeding outcomes in randomized controlled trials (RCTs) comparing direct oral anticoagulants (DOACs) at doses approved for AF vs. aspirin. METHODS We searched PubMed and Scopus for phase-III RCTs of DOACs at AF-approved doses vs. aspirin. Outcomes assessed were major-, intracranial-, gastrointestinal-, clinically-relevant-non-major- and fatal bleeding. We performed two subgroup analyses: one per patient population i.e. those at high risk of arterial or venous thromboembolism, and one per DOAC. We also performed a meta-regression to assess the association with patient age. RESULTS In 4 eligible trials (20,440 patients) comparing DOACs vs. aspirin, the ORs were: 1.52 (95%CI: 0.91-2.53) for major bleeding in patients at high risk of arterial thromboembolism and 1.55 (95%CI:0.99-2.45, relative-risk-increase:55%, absolute-risk-increase:0.6%, number-needed-to-harm:170) in the overall analysis; 1.39 (95%CI:0.62-3.14) for intracranial bleeding in patients at high risk of arterial thromboembolism which was similar for the overall analysis; 1.27 (95%CI: 0.84-1.92) for gastrointestinal bleeding in patients at high risk of arterial thromboembolism and 1.26 (95%CI:0.86-1.85) in the overall analysis. Patient age was not a predictor of the magnitude of ORs for all bleeding outcomes. CONCLUSION The present meta-analysis does not support the use of aspirin over DOACs in AF. Accordingly, the level of evidence of the related recommendations should be upgraded, which in turn may reduce further the proportion of AF patients treated with antiplatelets.

Temporal trends of atrial fibrillation and/or rheumatic heart disease-related ischemic stroke, and anticoagulant use in Chinese population: An 8-year study. Int J Cardiol 2020; 322:258-264.

Abstract
BACKGROUND AND PURPOSE Underuse of anticoagulants in ischemic stroke patients with atrial fibrillation (AF) and/or rheumatic heart disease (RHD) is a global concern, especially in China. However, the extent to which anticoagulants are underused in AF and/or RHD-related ischemic stroke in China has not been well characterized. We aimed to explore the temporal trends of AF and/or RHD-related ischemic stroke patients, anticoagulation use and factors related to suboptimal use of anticoagulants in a Chinese population. METHODS Acute ischemic stroke patients admitted to department of neurology, West China hospital, Sichuan university were included from January 1st 2010 to December 31st 2017. Temporal trends of AF and RHD related ischemic strokes were compared over 2 year epochs (2010-2011, 2012-2013, 2014-2015 and 2016-2017). Multivariable logistic regression models were performed to evaluate the variables associated with non-anticoagulants at discharge. RESULTS Of 4357 acute ischemic stroke patients (≤7 days after onset) included between 2010 and 2017, 823(18.9%) were AF and/or RHD-related. Over the 8 years, the proportion of RHD-ischemic stroke decreased significantly from 7.8% in 2010-2011 to 4.5% in 2016-2017, whereas no reduction in AF-ischemic stroke was observed. There was an increase in the proportion of AF and/or RHD patients who were prescribed anticoagulants at discharge (from 26.4% to 45.1%, P for trend<0.001), while the proportion given antiplatelet therapy decreased with time (from 56.0% to 30.0%, P for trend<0.001). The use of non-vitamin K antagonist oral anticoagulants (NOAC) use at discharge remained low during the study period (2.1%).Older age (per 5 years increase, OR 1.91, 95% CI 1.28-2.86), higher NIHSS score on admission(OR 1.08, 95% CI 1.05-1.11), the presence of non-symptomatic hemorrhagic transformation(OR 2.54, 95% CI 1.67-3.94) and symptomatic hemorrhagic transformation(OR 3.04, 95% CI 1.14-9.73) were independently associated with non-anticoagulant use at discharge. However, patients with a prior diagnosis of AF/RHD and anticoagulation before admission were more likely to receive anticoagulants at discharge. CONCLUSIONS In an ischemic stroke population in China we found an increasing but still low use of anticoagulation. Further research is required on how to improve anticoagulation use at discharge in ischemic stroke patients, including access to NOAC's.

Abstract
Stroke remains one of the leading causes of long-term disability and mortality despite recent advances in acute thrombolytic therapies. In fact, the global lifetime risk of stroke in adults over the age of 25 is approximately 25%, with 24.9 million cases of ischemic stroke and 18.7 million cases of hemorrhagic stroke reported in 2015. One of the main challenges in developing effective new acute therapeutics and enhanced long-term interventions for stroke recovery is the heterogeneity of stroke, including etiology, comorbidities, and lifestyle factors that uniquely affect each individual stroke survivor. In this comprehensive review, we propose that future biomarker studies can be designed to support precision medicine therapeutic interventions after stroke. The current challenges in defining ideal biomarkers for stroke are highlighted, including consideration of disease course, age, lifestyle factors, and subtypes of stroke. This overview of current clinical trials includes biomarker collection, and concludes with an example of biomarker design for aneurysmal subarachnoid hemorrhage. With the advent of "-omics" studies, neuroimaging, big data, and precision medicine, well-designed stroke biomarker trials will greatly advance the treatment of a disease that affects millions globally every year.

Abstract
Stroke is one of the leading causes of morbidity and mortality in the United States. While age-adjusted stroke mortality was falling, it has leveled off in recent years due in part to advances in medical technology, health care options, and population health interventions. In addition to adverse trends in stroke-related morbidity and mortality across the broader population, there are sociodemographic inequities in stroke risk. These challenges can be addressed by focusing on predicting and preventing modifiable upstream risk factors associated with stroke, but there is a need to develop a practical framework that health care organizations can use to accomplish this task across diverse settings. Accordingly, this article describes the efforts and vision of the multi-stakeholder Predict & Prevent Learning Collaborative of the Value in Healthcare Initiative, a collaboration of the American Heart Association and the Robert J. Margolis, MD, Center for Health Policy at Duke University. This article presents a framework of a potential upstream stroke prevention program with evidence-based implementation strategies for predicting, preventing, and managing stroke risk factors. It is meant to complement existing primary stroke prevention guidelines by identifying frontier strategies that can address gaps in knowledge or implementation. After considering a variety of upstream medical or behavioral risk factors, the group identified 2 risk factors with substantial direct links to stroke for focusing the framework: hypertension and atrial fibrillation. This article also highlights barriers to implementing program components into clinical practice and presents implementation strategies to overcome those barriers. A particular focus was identifying those strategies that could be implemented across many settings, especially lower-resource practices and community-based enterprises representing broad social, economic, and geographic diversity. The practical framework is designed to provide clinicians and health systems with effective upstream stroke prevention strategies that encourage scalability while allowing customization for their local context.

Abstract
Background Anticoagulation for preventing stroke in atrial fibrillation is under-utilised despite evidence supporting its use, resulting in avoidable death and disability. We aimed to evaluate an intervention to improve the uptake of anticoagulation. Methods We carried out a national, cluster randomised controlled trial in the Australian primary health care setting. General practitioners received an educational session, delivered via telephone by a medical peer and provided information about their patients selected either because they were not receiving anticoagulation or for whom anticoagulation was considered challenging. General practitioners were randomised to receive feedback from a medical specialist about the cases (expert decisional support) either before or after completing a post-test audit. The primary outcome was the proportion of patients reported as receiving oral anticoagulation. A secondary outcome assessed antithrombotic treatment as appropriate against guideline recommendations. Results One hundred and seventy-nine general practitioners participated in the trial, contributing information about 590 cases. At post-test, 152 general practitioners (84.9%) completed data collection on 497 cases (84.2%). A 4.6% (Adjusted Relative Risk = 1.11, 95% CI = 0.86–1.43) difference in the post-test utilization of anticoagulation between groups was not statistically significant (p = 0.42). Sixty-one percent of patients in both groups received appropriate antithrombotic management according to evidence-based guidelines at post-test (Adjusted Relative Risk = 1.0; 95% CI = 0.85 to 1.19) (p = 0.97). Conclusions Specialist feed-back in addition to an educational session did not increase the uptake of anticoagulation in patients with AF.

Abstract
BACKGROUND Outcomes among atrial fibrillation (AF) patients may differ according to race/ethnicity and sex due to differences in biology, the prevalence of cardiovascular risk factors, and the use and effectiveness of AF treatments. We aimed to characterize patterns of cardiovascular risk across subgroups of AF patients by sex and race/ethnicity, since doing so may provide opportunities to identify interventions. We also evaluated whether these patterns changed over time. METHODS We utilized administrative claims data from the Optum Clinformatics® Datamart database from 2009 to 2015. Patients with AF with ≥6 months of enrollment prior to the first non-valvular AF diagnosis were included in the analysis. Final analysis utilized Cox proportional hazard models to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for cardiovascular outcomes stratified by sex and race/ethnicity. An additional analysis stratified outcomes by calendar year of AF diagnosis to evaluate changes in outcomes over time. RESULTS In a cohort of 380,636 AF patients, women had a higher risk of ischemic stroke [HR (95% CI): 1.25 (1.19, 1.31)] and lower risk of heart failure and myocardial infarction [HR (95% CI): 0.91 (0.88, 0.94) and 0.81 (0.77, 0.86), respectively)] compared to men. Black patients had elevated risk across all endpoints compared to whites, while Hispanics and Asian Americans showed no significant differences in any outcome compared to white patients. These sex and race/ethnic differences did not change over time. CONCLUSIONS We found sex and race/ethnic differences in risk of cardiovascular outcomes among AF patients, without evidence of improvement over time.

Abstract
Background and Purpose Atrial Fibrillation (AF) is the most common cardiac cause of ischemic stroke. However, the relation between AF and stroke care outcomes in diverse populations is understudied. We aimed to evaluate sex and race-ethnic disparities associated with AF in hospital stroke outcomes utilizing data from the FLorida PuErto Rico Atrial Fibrillation (FLiPER-AF) Stroke Study. Methods The study included 104,308 ischemic stroke cases with available information on AF status enrolled in a state-wide stroke registry from 2010 to 2016. Multivariable logistic regression models were performed to evaluate the association between AF and stroke outcomes and the modification effects on the associations by sex and by race-ethnicity, adjusted for socio-demographic status, vascular risk factors and stroke severity. Results AF was present in 23% of ischemic stroke cases. AF was associated with worse disability at discharge (OR=1.11, 95% CI, 1.04-1.18), less discharge to home (OR=0.89, 0.85-0.92), and longer length of hospital stay (LOS>6 days, OR=1.53, 1.46-1.60). Interaction analyses showed that the association between AF and less discharge to home was stronger in women than men (p for interaction <0.001), as well as in FL-whites than in FL-blacks, FL-Hispanics or PR-Hispanics (p for interaction=0.002). The association between AF and prolonged LOS was more prominent in PR-Hispanics than in FL-blacks, FL-Hispanics, or FL-whites (p for interaction <0.001). From 2010 to 2016, the effects of AF on hospital length of stay attenuated (p for interaction<0.001). Conclusions AF was associated with poor disability at discharge, less discharge to home, and prolonged hospital length of stay for acute stroke care. The effect of AF on length of stay attenuated over time. Sex and race-ethnic disparities were observed in the effect of AF on being less discharge to home and prolonged hospital stay. Further research is needed to identify and modify the biologic and systems of care contributors to these disparities.
