Association between neighborhood household income and inpatient atrial fibrillation outcomes.

BACKGROUND: The impact of socioeconomic status on the clinical outcomes of patients admitted to the hospital for atrial fibrillation (AF) is not well described. OBJECTIVE: The purpose of this study was to determine the association between median neighborhood household income (mNHI) and clinical outcomes among patients admitted to the hospital for AF. METHODS: We retrospectively analyzed primary AF hospitalizations from the United States National Inpatient Sample between 2016 and 2020. The analyzed sample was divided into quartiles based on the mNHI in the zip code of the patient's residence. The lowest quartile was used as the reference category. Study outcomes included inpatient procedure utilization (ablation, cardioversion, percutaneous left atrial appendage closure), length of stay, cost, mortality, and disposition. Weighted multivariable logistic and linear regression, adjusting for multiple patient and hospital-level characteristics, was performed. RESULTS: Patients in the highest mNHI quartile had lower comorbidity burden, lower in-hospital mortality (odds ratio [OR] 0.78; 95% confidence interval [CI] 0.7-0.87; P <.001), lower discharges to care facility (OR 0.86; 95% CI 0.83-0.9; P <.001), shorter length of stay (adjusted mean difference -0.26; 95% CI -0.30 to -0.22; P <.001), higher procedure utilization, and higher health care costs ($12,124 vs $10,018) compared to the lowest mNHI quartile patients. CONCLUSION: We identified significantly higher in-hospital mortality and lower procedural/resource utilization in patients living in lower-income neighborhoods compared to higher-income neighborhoods. Further research is needed to better understand the drivers of these disparities and the strategies to improve health care disparities between socioeconomic groups.

Racial and ethnic disparities in cardiovascular disease - analysis across major US national databases.

BACKGROUND: There are several studies that have analyzed disparities in cardiovascular disease (CVD) health using a variety of different administrative databases; however, a unified analysis of major databases does not exist. In this analysis of multiple publicly available datasets, we sought to examine racial and ethnic disparities in different aspects of CVD, CVD-related risk factors, CVD-related morbidity and mortality, and CVD trainee representation in the US. METHODS: We used National Health and Nutrition Examination Survey, National Ambulatory Medical Care Survey, National Inpatient Sample, Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research, United Network for Organ Sharing, and American Commission for Graduate Medical Education data to evaluate CVD-related disparities among Non-Hispanic (NH) White, NH Black and Hispanic populations. RESULTS: The prevalence of most CVDs and associated risk factors was higher in NH Black adults compared to NH White adults, except for dyslipidemia and ischemic heart disease (IHD). Statins were underutilized in IHD in NH Black and Hispanic patients. Hospitalizations for HF and stroke were higher among Black patients compared to White patients. All-cause, CVD, heart failure, acute myocardial infarction, IHD, diabetes mellitus, hypertension and cerebrovascular disease related mortality was highest in NH Black or African American individuals. The number of NH Black and Hispanic trainees in adult general CVD fellowship programs was disproportionately lower than NH White trainees. CONCLUSION: Racial disparities are pervasive across the spectrum of CVDs with NH Black adults at a significant disadvantage compared to NH White adults for most CVDs.

Neprilysin Inhibitors in Heart Failure: The Science, Mechanism of Action, Clinical Studies, and Unanswered Questions.

This article provides a contemporary review and a new perspective on the role of neprilysin inhibition in heart failure (HF) in the context of recent clinical trials and addresses potential mechanisms and unanswered questions in certain HF patient populations. Neprilysin is an endopeptidase that cleaves a variety of peptides such as natriuretic peptides, bradykinin, adrenomedullin, substance P, angiotensin I and II, and endothelin. It has a broad role in cardiovascular, renal, pulmonary, gastrointestinal, endocrine, and neurologic functions. The combined angiotensin receptor and neprilysin inhibitor (ARNi) has been developed with an intent to increase vasodilatory natriuretic peptides and prevent counterregulatory activation of the angiotensin system. ARNi therapy is very effective in reducing the risks of death and hospitalization for HF in patients with HF and New York Heart Association functional class II to III symptoms, but studies failed to show any benefits with ARNi when compared with angiotensin-converting enzyme inhibitors or angiotensin receptor blocker in patients with advanced HF with reduced ejection fraction or in patients following myocardial infarction with left ventricular dysfunction but without HF. These raise the questions about whether the enzymatic breakdown of natriuretic peptides may not be a very effective solution in advanced HF patients when there is downstream blunting of the response to natriuretic peptides or among post-myocardial infarction patients in the absence of HF when there may not be a need for increased natriuretic peptide availability. Furthermore, there is a need for additional studies to determine the long-term effects of ARNi on albuminuria, obesity, glycemic control and lipid profile, blood pressure, and cognitive function in patients with HF.

Misconceptions and Facts about Heart Failure with Reduced Ejection Fraction.

Heart failure with reduced ejection fraction is a significant driver of morbidity and mortality. There are common misconceptions regarding the disease processes underlying heart failure and best practices for therapy. The terms heart failure with reduced ejection fraction and left ventricular systolic dysfunction are not interchangeable terms. Key therapies for heart failure with reduced ejection fraction target the underlying disease processes, not the left ventricular ejection fraction alone. The absence of congestion does not rule out heart failure. Patients with cardiac amyloidosis can also present with heart failure with reduced ejection fraction. A rise in serum creatinine in acute heart failure exacerbation is not associated with tubular injury. Guideline directed medical therapy should be continued during acute exacerbations of heart failure with reduced ejection fraction and should be started in the same hospitalization in new diagnoses. Marginal blood pressure is not a relative contraindication to optimal guideline directed medical therapy. Guideline directed medical therapy should be continued even if ejection fraction improves. There are other therapies that provide significant benefit besides the four key medications in guideline directed medical therapy.

Use of Preventive Cardiovascular Health Care Among Asian American Individuals: A National Health Interview Survey Study.

The risk of atherosclerotic cardiovascular disease (ASCVD) varies across Asian Americans. Heterogeneity in preventive health care use may have a role in health disparity across Asian American populations. We included 318,069 White, Chinese, Asian Indian, Filipino, and 'other Asian' (Japanese, Korean, and Vietnamese) participants with and without a self-reported history of ASCVD or ASCVD risk factors (including hypertension, hypercholesterolemia, and diabetes) from 2006 to 2018 National Health Interview Survey (NHIS). We used multivariable logistic regression models adjusted for age, sex, US birth, education, insurance coverage, and a comorbidity score to assess the association between Asian American race/ethnicity and annual health care use. Adjusted odds ratios (aOR) with 95% confidence intervals were reported. Of the total, 187,093 participants did not report ASCVD or ASCVD risk factors (mean age, 40.2±0.1 years; 52% women), and 130,976 participants reported ASCVD or ASCVD risk factors (mean age, 58.3±0.9 years; 49.5% women). Compared with White individuals, among the group without ASCVD or ASCVD risk factors (N=187,093), 'other Asian' adults were less likely to visit a general practitioner (aOR=0.80, 0.72-0.89), or check blood pressure (aOR=0.77, 0.66-0.89), blood cholesterol (aOR=0.80, 0.70-0.92), and fasting blood sugar (aOR=0.73, 0.63-0.84). Among participants with ASCVD or ASCVD risk factors (N=130,976), Asian Indian adults were more likely to visit a general practitioner (aOR=1.29, 1.01-1.66), or check blood pressure (aOR=1.27, 0.83-1.96), blood cholesterol (aOR=1.46, 1.00-2.15), and fasting blood sugar (aOR=1.49, 1.11-1.99). Annual preventive health care use is heterogeneous across the Asian American populations.

Management of Patients at Risk for and With Left Ventricular Thrombus: A Scientific Statement From the American Heart Association.

Despite the many advances in cardiovascular medicine, decisions concerning the diagnosis, prevention, and treatment of left ventricular (LV) thrombus often remain challenging. There are only limited organizational guideline recommendations with regard to LV thrombus. Furthermore, management issues in current practice are increasingly complex, including concerns about adding oral anticoagulant therapy to dual antiplatelet therapy, the availability of direct oral anticoagulants as a potential alternative option to traditional vitamin K antagonists, and the use of diagnostic modalities such as cardiac magnetic resonance imaging, which has greater sensitivity for LV thrombus detection than echocardiography. Therefore, this American Heart Association scientific statement was commissioned with the goals of addressing 8 key clinical management questions related to LV thrombus, including the prevention and treatment after myocardial infarction, prevention and treatment in dilated cardiomyopathy, management of mural (laminated) thrombus, imaging of LV thrombus, direct oral anticoagulants as an alternative to warfarin, treatments other than oral anticoagulants for LV thrombus (eg, dual antiplatelet therapy, fibrinolysis, surgical excision), and the approach to persistent LV thrombus despite anticoagulation therapy. Practical management suggestions in the form of text, tables, and flow diagrams based on careful and critical review of actual study data as formulated by this multidisciplinary writing committee are given.

Association Between Social Vulnerability Index and Cardiovascular Disease: A Behavioral Risk Factor Surveillance System Study.

Background Social and environmental factors play an important role in the rising health care burden of cardiovascular disease. The Centers for Disease Control and Prevention developed the Social Vulnerability Index (SVI) from US census data as a tool for public health officials to identify communities in need of support in the setting of a hazardous event. SVI (ranging from a least vulnerable score of 0 to a most vulnerable score of 1) ranks communities on 15 social factors including unemployment, minoritized groups status, and disability, and groups them under 4 broad themes: socioeconomic status, housing and transportation, minoritized groups, and household composition. We sought to assess the association of SVI with self-reported prevalent cardiovascular comorbidities and atherosclerotic cardiovascular disease (ASCVD). Methods and Results We performed a retrospective cohort analysis of adults (≥18 years) in the Behavioral Risk Factor Surveillance System 2016 to 2019. Data regarding self-reported prevalent cardiovascular comorbidities (including diabetes, hypertension, hyperlipidemia, smoking, substance use), and ASCVD was captured using participants' response to a structured telephonic interview. We divided states on the basis of the tertile of SVI (first-participant lives in the least vulnerable group of states, 0-0.32; to third-participant lives in the most vulnerable group of states, 0.54-1.0). Multivariable logistic regression models adjusting for age, race and ethnicity, sex, employment, income, health care coverage, and association with federal poverty line were constructed to assess the association of SVI with cardiovascular comorbidities. Our study sample consisted of 1 745 999 participants ≥18 years of age. States in the highest (third) tertile of social vulnerability had predominantly Black and Hispanic adults, lower levels of education, lower income, higher rates of unemployment, and higher rates of prevalent comorbidities including hypertension, diabetes, chronic kidney disease, hyperlipidemia, substance use, and ASCVD. In multivariable logistic regression models, individuals living in states in the third tertile of SVI had higher odds of having hypertension (odds ratio (OR), 1.14 [95% CI, 1.11-1.17]), diabetes (OR, 1.12 [95% CI, 1.09-1.15]), hyperlipidemia (OR, 1.09 [95% CI, 1.06-1.12]), chronic kidney disease (OR, 1.17 [95% CI, 1.12-1.23]), smoking (OR, 1.05 [95% CI, 1.03-1.07]), and ASCVD (OR, 1.15 [95% CI, 1.12-1.19]), compared with those living in the first tertile of SVI. Conclusions SVI varies across the US states and is associated with prevalent cardiovascular comorbidities and ASCVD, independent of age, race and ethnicity, sex, employment, income, and health care coverage. SVI may be a useful assessment tool for health policy makers and health systems researchers examining multilevel influences on cardiovascular-related health behaviors and identifying communities for targeted interventions pertaining to social determinants of health.

SGLT-2 Inhibitors for Patients with Heart Failure: What Have We Learned Recently?

PURPOSE OF REVIEW: In this review, we discuss the mechanisms of action of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and the purported protective effects for mitigating heart failure (HF)-related outcomes. RECENT FINDINGS: Major randomized clinical trials have demonstrated the cardiovascular safety and efficacy of SGLT-2i among patients without known HF and those with established HF with reduced ejection fraction or preserved ejection fraction (HFrEF and HFpEF respectively). Recent HF guidelines have incorporated SGLT-2i in HF treatment algorithms. SGLT-2i have emerged as a novel treatment for both prevention of HF and reduction of cardiovascular morbidity and mortality among patients with existing HFrEF or HFpEF.

Mental Health and Access to Medical Care in Patients with Chronic Cardiovascular Conditions: An Analysis of the Behavior Risk Factor Surveillance System.

INTRODUCTION: Poor mental health is associated with worse outcomes for chronic diseases. It is unclear whether mental illness predisposes to difficulties with healthcare access. METHODS: Using a combined dataset of the 2016-2019 Behavioral Risk Factor Surveillance System, this study focused on individuals who reported a chronic cardiovascular condition. Weighted multivariable logistic regression analyses were used to explore the association between domains of mental health and measures of healthcare access including delaying medical care, more than one year since last routine checkup, lack of a primary care physician, and cost-related medication nonadherence. RESULTS: Among 1,747,397 participants, 27% had a chronic cardiovascular condition, 12% had clinical depression, and 12% had poor mental health. Those with poor mental health (OR 3.20 [3.08 - 3.33]) and clinical depression (OR 2.43 [2.35 - 2.52]) were more likely to report delays in medical care. Those with greater stress frequency (OR 8.47 [6.84 - 10.49] stressed all of the time), lower levels of emotional support received (OR 3.07 [2.21 - 4.26] rarely get needed emotional support), and greater life dissatisfaction (6.66 [4.14 - 10.70] very dissatisfied) reported greater delays in medical care. CONCLUSIONS: Individuals with poor mental health have greater difficulty accessing medical care independent of socioeconomic variables.

Endpoints in Heart Failure Drug Development.

Heart failure (HF) is a major health problem worldwide. The development of effective drug and/or device therapy is crucial to mitigate the significant morbidity, mortality and healthcare costs associated with HF. The choice of endpoint in clinical trials has important practical and clinical implications. Outcomes of interest including mortality and HF hospitalisations provide robust evidence for regulatory approval granted there is sufficiency of safety data. At the same time, it is important to recognise that HF patients experience significant impairments in functional capacity and quality of life, underscoring the need to incorporate parameters of symptoms and patient-reported outcomes in clinical trials. In this review, the authors summarise the evolution and definition of cardiovascular endpoints used in clinical trials, discuss approaches to study design to allow the incorporation of mortality, morbidity and functional endpoints and, finally, examine the current challenges and suggest steps for the development of cardiovascular endpoints that are effective, meaningful and meet the needs of all relevant stakeholders, including patients, physicians regulators and sponsors.

Trypanosoma cruzi in Nonischemic Cardiomyopathy Patients, Houston, Texas, USA.

To investigate possible cardiac manifestations of Chagas disease, we tested 97 Latinx patients with nonischemic cardiomyopathy in Houston, Texas, USA, for Trypanosoma cruzi infection. We noted a high prevalence of underdiagnosed infection and discrepant results in clinical diagnostic assays. Latinx cardiac patients in the United States would benefit from laboratory screening for T. cruzi infection.

Sex-Related Disparities in Cardiovascular Health Care Among Patients With Premature Atherosclerotic Cardiovascular Disease.

Importance: There is a paucity of data regarding secondary prevention care disparities in women with premature and extremely premature atherosclerotic cardiovascular disease (ASCVD), defined as an ASCVD event at 55 years or younger and 40 years or younger, respectively. Objective: To evaluate sex-based differences in antiplatelet agents, any statin, high-intensity statin (HIS) therapy, and statin adherence in patients with premature and extremely premature ASCVD. Design, Setting, and Participants: This was a cross-sectional, multicenter, nationwide VA health care system-based study with patients enrolled in the Veterans With Premature Atherosclerosis (VITAL) registry. The study assessed patients who had at least 1 primary care visit in the Veterans Affairs (VA) health care system from October 1, 2014, to September 30, 2015. Participants included 147 600 veteran patients with premature ASCVD, encompassing ischemic heart disease (IHD), ischemic cerebrovascular disease (ICVD), and peripheral arterial disease (PAD). Exposures: Women vs men with premature and extremely premature ASCVD. Main Outcomes and Measures: Antiplatelet use, any statin use, HIS use, and statin adherence (proportion of days covered [PDC] ≥0.8). Results: We identified 10 413 women and 137 187 men with premature ASCVD (age ≤55 years) and 1340 women and 8145 men with extremely premature (age ≤40 years) ASCVD. Among patients with premature and extremely premature ASCVD, women represented 7.1% and 14.1% of those groups, respectively. When compared with men, women with premature ASCVD had a higher proportion of African American patients (36.1% vs 23.8%) and lower proportions of Asian patients (0.5% vs 0.7%) and White patients (56.1% vs. 68.1%). In the extremely premature ASCVD group, women had a comparatively higher proportion of African American patients (36.8% vs 23.2%) and lower proportion of White patients (55.0% vs 67.8%) and Asian patients (1.3% vs 1.5%) than men. Among patients with premature IHD, women received less antiplatelet (adjusted odds ratio [AOR], 0.47, 95% CI, 0.45-0.50), any statin (AOR, 0.62; 95% CI, 0.59-0.66), and HIS (AOR, 0.63; 95% CI, 0.59-0.66) therapy and were less statin adherent (mean [SD] PDC, 0.68 [0.34] vs 0.73 [0.31]; ß coefficient: -0.02; 95% CI, -0.03 to -0.01) compared with men. Similarly, women with premature ICVD and premature PAD received comparatively less antiplatelet agents, any statin, and HIS. Among patients with extremely premature ASCVD, women also received less antiplatelet therapy (AOR, 0.61; 95% CI, 0.53-0.70), any statin therapy (AOR,0.51; 95% CI, 0.44-0.58), and HIS therapy (AOR, 0.45; 95% CI, 0.37-0.54) than men. There were no sex-associated differences in statin adherence among patients with premature ICVD, premature PAD, or extremely premature ASCVD. Conclusions and Relevance: This cross-sectional study revealed that women veterans with premature ASCVD and extremely premature ASCVD receive less optimal secondary prevention cardiovascular care in comparison with men. Women with premature ASCVD, particularly those with IHD, were also less statin adherent. Multidisciplinary and patient-centered interventions are needed to improve these disparities in women.

Racial and geographic disparities in influenza vaccination in the U.S. among individuals with atherosclerotic cardiovascular disease: Renewed importance in the setting of COVID-19.

INTRODUCTION: The importance of receiving an annual influenza vaccine among patients with atherosclerotic cardiovascular disease (ASCVD) is well established. With the rapid community spread and the possibility of another wave of COVID-19 infections in the fall, receiving an influenza vaccine is of particular importance to mitigate the risk associated with overlapping influenza and COVID-19 infections. METHODS: We utilized cross-sectional data from the 2016 to 2019 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative U.S. telephone-based survey of adults 18 years or older. Race/ethnicity was our exposure of interest. We assessed the relative difference in influenza vaccination by race/ethnicity for each U.S. state in the overall U.S. population and among those with ASCVD as prevalence of receipt of influenza vaccination among Blacks or Hispanics minus prevalence among Whites divided by prevalence among Whites. We used multivariable-adjusted logistic regression models to evaluate the association between socioeconomic risk factors and receipt of influenza vaccination. RESULTS: The study population consisted of 1,747,397 participants of whom 21% were older than 65 years, 51% women, 63% White, 12% Black, 17% Hispanic, and 9% with history of ASCVD. The receipt of influenza vaccine was 38% in the overall population and 51% among those with self-reported ASCVD, which translates to approximately to 97 million and 12 million US adults, respectively. The receipt of influenza vaccine among individuals with ASCVD was 54% for Whites, 45% for Blacks, and 42% for Hispanics (p<0.001). In the overall U.S. population, the median (interquartile range) relative difference for influenza vaccination between Blacks and Whites was 17% (-27%, -9%) and -22% (-29%, -9%) between Hispanics and Whites across all U.S. states. Among individuals with and without ASCVD, age older than 65 years, greater than college education, higher income, and having a primary care physician were significantly associated with higher odds of receipt of influenza vaccination, while being employed, lack of healthcare coverage, Black race, and delay in healthcare access were significantly inversely associated with having received an influenza vaccine. CONCLUSIONS: Only 50% patients with ASCVD receive influenza vaccines. The receipt of influenza vaccination among individuals with ASCVD is lower among Blacks and Hispanics compared to Whites with significant state-level variation. There are important socioeconomic determinants that are associated with receipt of the influenza vaccine.

Premature Atherosclerotic Cardiovascular Disease: What Have We Learned Recently?

PURPOSE OF REVIEW: In contrast to patients with non-premature atherosclerotic cardiovascular disease (ASCVD), patients with premature ASCVD have not observed a similar decline in cardiovascular mortality and recurrent adverse events. We sought to review the underlying risk factors, potential gaps in medical management, associated outcomes, and tools for risk prognostication among patients with premature ASCVD. RECENT FINDINGS: In addition to traditional cardiovascular risk factors (i.e., diabetes, familial hypercholesterolemia), non-traditional risk factors such as chronic inflammatory conditions, recreational drug use, genetics, and pregnancy-related complications play a key role in development and progression of premature ASCVD. Patients with premature ASCVD, and especially women, receive less optimal medical management as compared to their non-premature counterparts. There is an increasing prevalence of cardiovascular risk factors among young adults. Hence, this population remains at an elevated risk for premature ASCVD and subsequent adverse cardiovascular events. Future studies evaluating different risk assessment tools and focusing on young patients across all three major domains of ASCVD are needed.
