Background: Multiple socially determined vulnerabilities (SDV) to health disparities often cluster within the same individual. Previous studies have shown that SDV are separately associated with increased risk of heart failure (HF). As there may be a cumulative effect of these SDVs in the same individual, understanding their joint impact on the incidence of HF is critical. Methods: REGARDS is a national prospective cohort study that recruited 30,239 adults <45 years of age from 2003-2007 with ongoing follow-up. We followed participants free of HF at baseline for incident HF hospitalization through December 31, 2016. Guided by the Healthy People 2020 framework, we examined 10 potential SDVs, retaining those that were associated with incident HF (p<0.10) and creating a count of SDV (0, 1, 2, 3+). We used Cox models to examine associations between the SDV count and incident HF, adjusting for potential confounders. Since disparities in HF have been shown to be greatest in younger individuals models were stratified by age. Results: The 25,790 participants were followed for a median of 10.1 years (IQR 6.5, 11.9); their mean age at baseline was 64.8, 55%% were women, and 40% were blacks. In age-adjusted models, Black race, low educational attainment, low annual household income, zip code poverty, poor public health infrastructure, and lack of health insurance were significantly associated with incident HF. In fully adjusted models, among those 45-64 years, compared to having no SDV, having a SDV was significantly associated with incident HF, with a trend toward a higher count conferring greater risk (Fig. 1). There was no association in other age groups. Conclusions: An increased number of SDVs was associated with risk of incident HF hospitalization among adults <65 years, even after adjustment for cardiovascular risk factors. Using a simple count of SDVs that could be incorporated into the social history during clinical assessment may identify younger individuals at increased risk of incident HF.

Background: Socially determined vulnerabilities (SDVs) to health disparities often cluster within the same individual. SDVs are separately associated with increased risk of heart failure (HF). The objective of this study was to determine the cumulative effect of SDVs to health disparities on incident HF hospitalization. Methods and Results: Using the REGARDS (Reasons for Geographic and Racial Differences in Stroke) cohort study, we studied 25 790 participants without known HF and followed them for 10+ years. Our primary outcome was an incident HF hospitalization through December 31, 2016. Guided by the Healthy People 2020 framework for social determinants of health, we examined 10 potential SDVs. We retained SDVs associated with incident HF hospitalization ( P <0.10) and created an SDV count (0, 1, 2, 3+). Using the count, we estimated Cox proportional hazard models to examine associations with incident HF hospitalization, adjusting for potential confounders. Models were stratified by age (45–64, 65–74, and 75+ years) because past reports suggest greater disparities in HF incidence at younger ages. Participants were followed for a median of 10.1 years (interquartile range, 6.5–11.9). Black race, low educational attainment, low annual household income, zip code poverty, poor public health infrastructure, and lack of health insurance were associated with incident HF hospitalization. In adjusted models, among those 45 to 64 years, compared with having no SDV, having 1 SDV (hazard ratio, 1.85 [95% CI, 1.12–3.05]), 2 SDVs (hazard ratio, 2.12 [95% CI, 1.28–3.50]), and 3+ SDVs (hazard ratio, 2.45 [95% CI, 1.48–4.04]) were significantly associated with incident HF hospitalization ( P for trend, 0.001). We observed no significant associations for older individuals. Conclusions: A greater number of SDVs significantly increased risk of incident HF hospitalization among adults <65 years, which persisted after adjustment for cardiovascular risk factors. Using a simple SDV count that could be obtained from a social history during clinical assessment may identify younger individuals at increased risk.

SummaryPathologic alterations in haemostasis cause bleeding disorders, but it is unknown if variation within the normal range relates to intracerebral haemorrhage (ICH) risk. It was our objective to assess the prospective associations of haemostasis biomarkers with ICH risk. The REasons for Geographic and Racial Differences in Stroke study (REGARDS) recruited 30,239 U. S. individuals aged ≥45 years. ICH was ascertained through biannual telephone contact and review of deaths followed by medical record evaluation. Haemostasis biomarkers (factor VIII (FVIII), factor IX (FIX), factor XI (FXI), fibrinogen, protein C, and D-dimer) were measured in a case cohort study consisting of ICH and a 1,104 person cohort random sample. The hazard ratio (HR) and 95 % confidence interval (CI) by biomarker were estimated using Cox models and adjusted for ICH risk factors. Individuals with a prior history of stroke, ICH or on warfarin were excluded. Over a median 5.8 years 66 ICH occurred. Fibrinogen, FVIII, FXI, and protein C were not associated with ICH risk in any analysis. Lower FIX increased risk of ICH with the bottom versus the top tertile of FIX associated with an HR of 5.68 (95 % CI 2.30, 14.05). D-dimer demonstrated a non-linear relationship with a potential threshold effect with increased risk only in the top 5th percentile (HR 3.22; 95 % CI 1.01, 10.31; pnon-linear = 0.04).In conclusion, low FIX levels within the normal range were associated with increased ICH risk. These data suggest non-pathologic alterations in haemostasis impact intracranial bleeding risk.

Drug Use Disorder

Background: Several cardiotoxic substances contribute to the development of heart failure (HF). The burden of comorbid substance use disorders (SUD) among patients with HF is under-characterized. Objectives: To describe the national burden of comorbid SUD (tobacco, alcohol, or drug use disorders) among hospitalized HF patients in the U.S. Methods: We used data from the 2014 National Inpatient Sample to calculate the proportion of hospitalizations for a primary HF admission with tobacco, alcohol, or drug use disorder diagnoses, accounting for demographic factors. Drug use disorder analysis was further sub-divided into specific illicit substance categories. Results: There were a total of 989,080 HF hospitalizations of which 35.3% (n=348,995) had a documented SUD. Tobacco use disorder (TUD) was most common (n= 327,220, 33.1%) followed by drug use disorder (DUD) (n=34,600, 3.5%) and alcohol use disorder (AUD) (n=34,285, 3.5%). Female sex was associated with less TUD (OR 0.59; 95% CI, 0.58-0.60), AUD (OR 0.23; 95% CI, 0.22-0.25) or DUD (OR 0.58; 95% CI 0.55-0.62). Tobacco, alcohol, cocaine, and opioid use disorders were highest among HF patients age 45 to 55, while cannabis and amphetamine use was highest in those <45 years. Native American race (versus White) was associated with increased risk of AUD (OR 1.67; 95% CI 1.27-2.20). Black race was associated with increased risk of AUD (OR 1.09; 95% CI 1.02-1.16) or DUD (OR 1.63; 95% CI 1.53-1.74). Medicaid insurance (versus Medicare) was associated with greater TUD (OR 1.27; 95% CI 1.23-1.32), AUD (OR 1.74; 95% CI 1.62-1.87), and DUD (OR 2.15; 95% CI 2.01-2.30). Decreasing quartiles of median household income were associated with increasing SUD. Conclusions: Comorbid SUD disproportionately affects certain HF populations, including men, younger age groups, lower SES patients, and race/ethnic minorities. Further research on interventions to improve prevention and treatment of SUD among hospitalized HF patients are needed given the high rates of SUD in this population. Systematically screening hospitalized HF patients for SUD may reveal opportunities for treatment and secondary prevention.

Social determinants contribute to disparities in incident CHD but it is not known if they have an additive effect. We hypothesized that having more socially determined vulnerabilities to health disparities is associated with increased risk of incident CHD in the REGARDS study, a large biracial prospective cohort with physiological and survey measures. Experts adjudicated incident fatal and nonfatal CHD over 10 years of follow-up. Vulnerabilities included black race, low education, low income, and Southeastern US residence. The risks for CHD outcomes associated with 1, 2, and 3+ vs 0 vulnerabilities were calculated with Cox proportional hazards models adjusted for medical conditions, functional status, health behaviors, and physiologic variables. Of the 19,645 participants free of CHD at baseline (mean age 64 years, 57% women), 16% had 0 vulnerabilities, 36% had 1, 29% had 2, and 18% had 3+. Increasing numbers of vulnerabilities were associated with higher incidence (Figure) and risk of CHD that attenuated somewhat after multivariable adjustment (Table). These findings may provide a method of risk stratification useful for population health management.

Introduction: Racial differences in atrial fibrillation (AF) prevalence and disparities in treatment are well established; however, racial differences in outcomes among patients hospitalized with AF are less clear. We assessed racial differences in complications related to AF in a representative sample of AF hospitalization in the United States. Methods: We identified adults (≥ 40 years) with a principal diagnosis of AF and length of stay (LOS) among survivors of 1-30 days using weighted national estimates from the Nationwide Inpatient Sample. We excluded patients undergoing cardiac surgery or with missing covariates. Annual AF hospitalization rates by race were calculated using the total US population obtained from the US Census Bureau. We used multivariable regression models (covariates listed in Table) to examine associations of race with heart failure and hospital mortality among patients admitted with AF. Results: 2,244,036 AF hospitalizations (85% White, 6.7% Black, 5.0% Hispanic and 1.4% Asian/Pacific Islander) were analyzed from 2001-09. Hospitalization and outcome data by year are summarized in the table. Across all studied years, Blacks had lower AF hospitalization rates than Whites. Yet in all study years, mean LOS was longer for Blacks (range 4.2-4.6 days) than Whites (range 3.4-3.6 days). Blacks consistently had increased risk of in-hospital heart failure (Odds Ratio [OR] ranged from 1.5 [1.4, 1.7] to 1.7 [1.6, 1.9] across years) and death (OR, 1.5 [1.1, 2.1] to 2.3 [1.7, 3.0]) compared with Whites after adjustment for comorbidities. Conclusions: Although Blacks have lower incidence of hospitalizations for AF, they experience higher risk of heart failure, longer LOS, and greater mortality compared with Whites hospitalized with AF. Further public health investigation is warranted to examine the causes for disparities in outcomes among Blacks with AF and identify modifiable factors that may improve outcomes of Blacks with AF.

Ckd Stage

Background: The majority of people with chronic kidney disease (CKD) are unaware of their kidney disease. Assessing the clinical significance of increasing CKD awareness has critical public health and healthcare delivery implications. Whether CKD awareness among persons with CKD is associated with longitudinal health behaviors, disease management, and health outcomes is unknown. Methods: We analyzed data from participants with CKD in the REasons for Geographic And Racial Differences in Stroke study, a national, longitudinal, population-based cohort. Our predictor was participant CKD awareness. Outcomes were (1) health behaviors (smoking avoidance, exercise, and nonsteroidal anti-inflammatory drug use); (2) CKD management indicators (angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use, statin use, systolic blood pressure, fasting blood glucose, and body mass index); (3) change in estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR); and (4) health outcomes (incident end-stage kidney disease [ESKD], coronary heart disease [CHD], stroke, and death). Logistic and linear regressions were used to examine the association of baseline CKD awareness with outcomes of interest, adjusted for CKD stage and participant demographic and clinical factors. Results: Of 6,529 participants with baseline CKD, 285 (4.4%) were aware of their CKD. Among the 3,586 participants who survived until follow-up (median 9.5 years), baseline awareness was not associated with subsequent odds of health behaviors, CKD management indicators, or changes in eGFR and UACR in adjusted analyses. Baseline CKD awareness was associated with increased risk of ESKD (adjusted hazard ratio [aHR] 1.44; 95% CI 1.08–1.92) and death (aHR 1.18; 95% CI 1.00–1.39), but not with subsequent CHD or stroke, in adjusted models. Conclusions: Individuals aware of their CKD were more likely to experience ESKD and death, suggesting that CKD awareness reflects disease severity. Most persons with CKD, including those that are high-risk, remain unaware of their CKD. There was no evidence of associations between baseline CKD awareness and longitudinal health behaviors, CKD management indicators, or eGFR decline and albuminuria.

Background: It is currently unknown if premature atrial contractions (PACs) detected on the routine screening electrocardiogram are associated with an increased risk of ischemic stroke. Methods: We examined the association between PACs and ischemic stroke in 22,975 (mean age 64 ± 9.2; 56% women; 40% black) participants from the Reasons for Geographic and Racial Differences in Stroke study. Participants who were free of stroke at baseline were included. PACs were detected from centrally read electrocardiograms at baseline. Cox regression was used to examine the association between PACs and ischemic stroke events through March 31, 2014. Results: PACs were present in 1,687 (7.3%) participants at baseline. In a Cox regression model adjusted for stroke risk factors and potential confounders, PACs were associated with an increased risk of ischemic stroke (hazards ratio (HR) 1.34, 95% CI 1.04-1.74). The relationship was limited to non-lacunar infarcts (HR 1.42, 95% CI 1.08-1.87), and not lacunar strokes (HR 1.01, 95% CI 0.51-2.03). An interaction by sex was detected, with the association between PACs and ischemic stroke being stronger among women (HR 1.82, 95% CI 1.29-2.56) than men (HR 1.03, 95% CI 0.69-1.52; p-interaction = 0.0095). Conclusion: PACs detected on the routine electrocardiogram are associated with an increased risk for non-lacunar ischemic strokes, especially in women.

The increased risk of violent victimization for adolescents relative to other age groups has recently become a major public health concern. The current study uses data from a multisite study of eighth grade youths attending public schools in 11 cities to determine the extent and nature of youth general and serious violent victimization among both sexes and five racial/ethnic groups in 11 diverse communities. This study explores differences in sex, race/ethnicity, and community independently and explores interactions between sex and community and race/ethnicity and community. Our findings suggest important differences in victimization prevalence and individual victimization rates by sex and community of residence. Racial differences were found to be closely tied to community. Policy implications resulting from our findings are discussed.

Background Haemostatic balance represented by low protein C (PC) and elevated factor VIII (FVIII) has been inconsistently associated with stroke and coronary heart disease (CHD) risk. Objective This article assesses whether an elevated FVIII and a low PC would increase cardiovascular risk more than either individually. Patients and Methods REGARDS recruited 30,239 black and white U.S. participants aged ≥ 45 years between 2003 and 2007. FVIII and PC were measured in a case–cohort sample of 646 stroke, 654 CHD, and a 1,104-person random sample with follow-up for approximately 4.5 years. Hazard ratios (HRs) were estimated using Cox models adjusted for demographic and cardiovascular risk factors. Results Elevated FVIII (per standard deviation [SD] increase) was associated with increased risk of both stroke (HR, 1.26; 95% confidence interval [CI], 1.08, 1.46) and CHD (HR, 1.52; 95% CI, 1.29, 1.79), while there was no association of PC per SD decrease. For PC, there was a trend towards increased cardiovascular disease risk in the lowest values (bottom 5%). For stroke, there was no interaction between FVIII and low PC (p interaction = 0.55). For CHD, the adjusted HR of FVIII per SD increase was significantly greater with PC in the bottom 5% (HR, 3.59; 95% CI, 1.39, 8.29) than PC in the upper 95% (HR, 1.45; 95% CI, 1.23, 1.71; p interaction = 0.07). Conclusion Higher FVIII was associated with both CHD and stroke risk and the risk potentiated by low PC for CHD. Findings demonstrate that risks for cardiovascular diseases conferred by adverse levels of haemostasis biomarkers may be augmented by levels of other biomarkers.
