Abstract
Guideline-directed medical therapies and guideline-directed nonpharmacological therapies improve quality of life and survival in patients with heart failure (HF), but eligible patients, particularly women and individuals from underrepresented racial and ethnic groups, are often not treated with these therapies. Implementation science uses evidence-based theories and frameworks to identify strategies that facilitate uptake of evidence to improve health. In this scientific statement, we provide an overview of implementation trials in HF, assess their use of conceptual frameworks and health equity principles, and provide pragmatic guidance for equity in HF. Overall, behavioral nudges, multidisciplinary care, and digital health strategies increased uptake of therapies in HF effectively but did not include equity goals. Few HF studies focused on achieving equity in HF by engaging stakeholders, quantifying barriers and facilitators to HF therapies, developing strategies for equity informed by theory or frameworks, evaluating implementation measures for equity, and titrating strategies for equity. Among these HF equity studies, feasibility was established in using various educational strategies to promote organizational change and equitable care. A couple include ongoing randomized controlled pragmatic trials for HF equity. There is great need for additional HF implementation trials designed to promote delivery of equitable guideline-directed therapy.

The Wallet Biopsy: Medical Crowdfunding for Heart Transplantation. J Card Fail 2024; 30:722-727. [PMID: 38584015 DOI: 10.1016/j.cardfail.2023.12.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 12/04/2023] [Accepted: 12/05/2023] [Indexed: 04/09/2024]
Abstract
Financial considerations continue to impact access to heart transplantation. Transplant recipients face various costs, including, but not limited to, the index hospitalization, immunosuppressive medications, and lodging and travel to appointments. In this study, we sought to describe the state of crowdfunding for individuals being evaluated for heart transplantation. Using the search term heart transplant, 1000 GoFundMe campaigns were reviewed. After exclusions, 634 (63.4%) campaigns were included. Most campaigns were in support of white individuals (57.8%), males (63.1%) and adults (76.7%). Approximately 15% of campaigns had not raised any funds. The remaining campaigns fundraised a median of $53.24 dollars per day. Of the patients, 44% were admitted at the time of the fundraising. Within the campaigns in the United States, the greatest proportions were in the Southeast United States in non-Medicaid expansion states. These findings highlight the significant financial toxicities associated with heart transplantation and the need for advocacy at the governmental and payer levels to improve equitable access and coverage for all.

Abstract
BACKGROUND Progression to symptomatic heart failure is a complication of type 2 diabetes; heart failure onset in this setting is commonly preceded by deterioration in exercise capacity. OBJECTIVES The study sought to determine whether AT-001, a highly selective aldose reductase inhibitor, can stabilize exercise capacity among individuals with diabetic cardiomyopathy (DbCM) and reduced peak oxygen uptake (Vo2). METHODS A total of 691 individuals with DbCM meeting inclusion and exclusion criteria were randomized to receive placebo or ascending doses of AT-001 twice daily. Stratification at inclusion included region of enrollment, cardiopulmonary exercise test results, and use of sodium-glucose cotransporter 2 inhibitors or glucagon-like peptide-1 receptor agonists. The primary endpoint was proportional change in peak Vo2 from baseline to 15 months. Subgroup analyses included measures of disease severity and stratification variables. RESULTS The mean age was 67.5 ± 7.2 years, and 50.4% of participants were women. By 15 months, peak Vo2 fell in the placebo-treated patients by -0.31 mL/kg/min (P = 0.005 compared to baseline), whereas in those receiving high-dose AT-001, peak Vo2 fell by -0.01 mL/kg/min (P = 0.21); the difference in peak Vo2 between placebo and high-dose AT-001 was 0.30 (P = 0.19). In prespecified subgroup analyses among those not receiving sodium-glucose cotransporter 2 inhibitors or glucagon-like peptide-1 receptor agonists at baseline, the difference between peak Vo2 in placebo vs high-dose AT-001 at 15 months was 0.62 mL/kg/min (P = 0.04; interaction P = 0.10). CONCLUSIONS Among individuals with DbCM and impaired exercise capacity, treatment with AT-001 for 15 months did not result in significantly better exercise capacity compared with placebo.

Abstract
Heart failure (HF) is a complex syndrome traditionally classified by left ventricular ejection fraction (LVEF) cutpoints. Although LVEF is prognostic for risk of events and predictive of response to some HF therapies, LVEF is a continuous variable and cutpoints are arbitrary, often based on historical clinical trial enrichment decisions rather than physiology. Holistic evaluation of the treatment effects for therapies throughout the LVEF range suggests the standard categorization paradigm for HF merits modification. The multidisciplinary Heart Failure Collaboratory reviewed data from large-scale HF clinical trials and found that many HF therapies have demonstrated therapeutic benefit across a large range of LVEF, but specific treatment effects vary across that range. Therefore, HF should practically be classified by association with an LVEF that is reduced or not reduced, while acknowledging uncertainty around the precise LVEF cutpoint, and future research should evaluate new therapies across the continuum of LVEF.

Characterizing diabetic cardiomyopathy: baseline results from the ARISE-HF trial. Cardiovasc Diabetol 2024; 23:49. [PMID: 38302936 PMCID: PMC10835978 DOI: 10.1186/s12933-024-02135-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 01/15/2024] [Indexed: 02/03/2024] Open
Abstract
BACKGROUND Diabetic cardiomyopathy (DbCM) is a form of Stage B heart failure (HF) at high risk for progression to overt disease. Using baseline characteristics of study participants from the Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure (ARISE-HF) Trial we sought to characterize clinical characteristics of individuals with findings consistent with DbCM. METHODS Among study participants meeting inclusion criteria, clinical characteristics, laboratory testing, imaging, Kansas City Cardiomyopathy Questionnaire (KCCQ), Physical Activity Scale of the Elderly (PASE) and cardiopulmonary exercise testing (CPET) results were tabulated. Cluster phenogroups were identified. RESULTS Among 691 study participants (mean age 67.4 years; 50% were female), mean duration of type 2 diabetes mellitus (T2DM) was 14.5 years. The median (Q1, Q3) N-terminal pro-B type natriuretic peptide and high sensitivity cardiac troponin T were 71 (35, 135) ng/L and 9 [6, 12] ng/L. The most common echocardiographic abnormalities were reduced global longitudinal strain in 25.3% and impaired diastolic relaxation in 17.7%. Despite rather well-preserved KCCQ scores the average PASE score was markedly impaired at 155 accompanied by an average maximal oxygen consumption of 15.7 mL/Kg/minute on CPET. In K-means clustering, 4 phenogroups were identified including a higher-risk group with more advanced age, greater elevation of cardiac biomarkers, and more prevalent evidence for diastolic dysfunction and left ventricular hypertrophy. CONCLUSIONS Baseline data from the ARISE-HF Trial provide clinical characterization of individuals with T2DM and features of stage B HF, and may help clarify the diagnosis of DbCM. TRIAL REGISTRATION ARISE-HF, NCT04083339.

Abstract
PURPOSE OF REVIEW To discuss the prevailing racial and ethnic disparities in heart failure (HF) care by identifying barriers to equitable care and proposing solutions for achieving equitable outcomes. RECENT FINDINGS Throughout the entire spectrum of HF care, from prevention to implementation of guideline-directed medical therapy and advanced interventions, racial and ethnic disparities exist. Factors such as differential distribution of risk factors, poor access to care, inadequate representation in clinical trials, and discrimination from healthcare clinicians, among others, contribute to these disparities. Recent data suggests that despite improvements, disparities prevail in several aspects of HF care, hindering our progress towards equity in HF care. This review highlights the urgent need to address racial and ethnic disparities in HF care, emphasizing the importance of a multifaceted approach involving policy changes, quality improvement strategies, targeted interventions, and intentional community engagement. Our proposed framework was derived from existing research and emphasizes integrating equity into routine quality improvement efforts, tailoring interventions to specific populations, and advocating for policy transformation. By acknowledging these disparities, implementing evidence-based strategies, and fostering collaborative efforts, the HF community can strive to reduce disparities and achieve equity in HF care.

Temporal Changes in Racial and Ethnic Disparities in the Utilization of Left Atrial Appendage Occlusion in the United States. Am J Cardiol 2023; 204:53-63. [PMID: 37536205 DOI: 10.1016/j.amjcard.2023.07.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/20/2023] [Accepted: 07/04/2023] [Indexed: 08/05/2023]
Abstract
Racial and ethnic disparities in the access to left atrial appendage occlusion (LAAO) have been previously described. However, it remains unclear if there have been any changes in these disparities over the years and if the disparities include other racial and ethnic groups not previously studied. We aimed to determine the temporal evolution of the racial and ethnic disparities in the utilization of LAAO from 2016 to 2019. We conducted a retrospective cohort study using the National Inpatient Sample from 2016 to 2019. International Classification of Diseases, 10th edition codes were used to identify all adult admissions with atrial fibrillation (AF) and those who underwent LAAO. The sample was divided into Asian American and Pacific Islander, Black, Hispanic, White, and other races/ethnicities. Our primary outcome was the utilization of LAAO in patients admitted with a diagnosis of AF. The Cochran-Armitage test was conducted to evaluate the yearly trend in LAAO utilization stratified by race/ethnicity. Multivariable regression analysis was conducted to assess the association of race/ethnicity with multiple end points. A total of 59,415 patients underwent LAAO. The highest yearly increase in LAAO utilization was seen in White patients (trend: 0.16%, p <0.001). Furthermore, compared with White patients, the yearly increase in LAAO utilization was lower in all other racial/ethnic groups. Black patients had the lowest odds of who underwent LAAO (odds ratio = 0.45, 95% confidence interval 0.40 to 0.50, p <0.001). In conclusion, significant gaps exist in the utilization of LAAO between racial and ethnic groups, and they appear to continue worsening from 2016 to 2019.

Abstract
BACKGROUND Non-US citizens/non-US residents (NCNR) are a unique and growing population. Patterns of heart donation and heart transplantation (HT) within this subgroup have not been described fully. The purpose of this study was to evaluate the use of organs from NCNR donors and the characteristics and outcomes of NCNR HT recipients. METHODS All adult donors whose hearts were recovered for HT and all primary adult HT recipients from 2013 to 2020 were identified using the United Network for Organ Sharing. Donors and recipients were categorized as citizens, residents, or NCNR. NCNR were further categorized by reason for travel to the United States. Outcomes included mortality, infection, and rejection at 1-year after transplantation. RESULTS NCNR accounted for 0.4% (n = 77) of heart donors. Most NCNR donors identified as Hispanic (61%), were predominately recovered from the South and Southwest United States, and were less likely to express written documentation to be a donor compared with citizens and residents. NCNR accounted for 0.7% (n = 147) of all HT recipients. The majority identified as non-Hispanic White individuals (57.1%). Compared with citizens and residents, NCNR recipients seemed to be sicker, as evidenced by higher intra-aortic balloon pump use before HT and higher priority United Network for Organ Sharing status. Of NCNR recipients, 63% traveled to the United States for HT, predominately from Kuwait (29.9%) and Saudi Arabia (20%). At 1-year after transplant, there were no differences in mortality, infection, or rejection between the groups. CONCLUSIONS A growing subgroup of NCNR travel from countries with low HT rates to the United States for HT. This finding highlights the need for strategies to improve equitable access to HT domestically and abroad.

Rationale and design of the Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure Trial (ARISE-HF) in patients with high-risk diabetic cardiomyopathy. Am Heart J 2023; 256:25-36.

Abstract
BACKGROUND Diabetic cardiomyopathy (DbCM) is a specific form of heart muscle disease that may result in substantial morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM). Hyperactivation of the polyol pathway is one of the primary mechanisms in the pathogenesis of diabetic complications, including development of DbCM. There is an unmet need for therapies targeting the underlying metabolic abnormalities that drive this form of Stage B heart failure (HF). METHODS Aldose reductase (AR) catalyzes the first and rate-limiting step in the polyol pathway, and AR inhibition has been shown to reduce diabetic complications, including DbCM in animal models and in patients with DbCM. Previous AR inhibitors (ARIs) were limited by poor specificity resulting in unacceptable tolerability and safety profile. AT-001 is a novel investigational highly specific ARI with higher binding affinity and greater selectivity than previously studied ARIs. ARISE-HF (NCT04083339) is an ongoing Phase 3 randomized, placebo-controlled, double blind, global clinical study to investigate the efficacy of AT-001 (1000 mg twice daily [BID] and 1500 mg BID) in 675 T2DM patients with DbCM at high risk of progression to overt HF. ARISE-HF assesses the ability of AT-001 to improve or prevent decline in exercise capacity as measured by functional capacity (changes in peak oxygen uptake [peak VO2]) over 15 (and possibly 27) months of treatment. Additional endpoints include percentage of patients progressing to overt HF, health status metrics, echocardiographic measurements, and changes in cardiacbiomarkers. RESULTS The ARISE-HF Trial is fully enrolled. CONCLUSIONS This report describes the rationale and study design of ARISE-HF.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) (canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin), although initially developed as glucose-lowering drugs, provide significant beneficial effects on cardiorenal outcomes, including heart failure, regardless of type 2 diabetes status. Integration of SGLT-2is into clinical practice requires practical guidance for physicians about their use. To overcome physicians’ clinical inertia for SGLT-2i use, including addressing safety, potentially a barrier to their use, a roundtable discussion with physicians from three specialties (cardiology, endocrinology, and nephrology) was conducted. This review summarizes the physicians’ clinical experience and recommendations about SGLT-2i use across different patient populations, taking into consideration the beneficial effects of SGLT-2is and their safety. The key aspects discussed regarding SGLT-2i safety include acute effects on kidney function (estimated glomerular filtration rate acute dip upon SGLT-2i initiation and acute kidney injury), volume depletion, diabetic ketoacidosis, genitourinary infections, hyperkalemia, and hypoglycemia. To mitigate any potential risks related to SGLT-2i safety, physicians can make minor adjustments to an individual patient’s treatment plan, while retaining the SGLT-2i cardiorenal benefits for effective disease management. Recognition by physicians that the benefits of SGLT-2i use on clinical outcomes outweigh the risks will result in the integration of SGLT-2is into clinical practice and lead to improved patient care and outcomes.

Abstract
BACKGROUND Understanding trends in cardiovascular (CV) risk factors and CV disease according to age, sex, race, and ethnicity is important for policy planning and public health interventions. OBJECTIVES The goal of this study was to project the number of people with CV risk factors and disease and further explore sex, race, and ethnical disparities. METHODS The prevalence of CV risk factors (diabetes mellitus, hypertension, dyslipidemia, and obesity) and CV disease (ischemic heart disease, heart failure, myocardial infarction, and stroke) according to age, sex, race, and ethnicity was estimated by using logistic regression models based on 2013-2018 National Health and Nutrition Examination Survey data and further combining them with 2020 U.S. Census projection counts for years 2025-2060. RESULTS By the year 2060, compared with the year 2025, the number of people with diabetes mellitus will increase by 39.3% (39.2 million [M] to 54.6M), hypertension by 27.2% (127.8M to 162.5M), dyslipidemia by 27.5% (98.6M to 125.7M), and obesity by 18.3% (106.3M to 125.7M). Concurrently, projected prevalence will similarly increase compared with 2025 for ischemic heart disease by 31.1% (21.9M to 28.7M), heart failure by 33.0% (9.7M to 12.9M), myocardial infarction by 30.1% (12.3M to 16.0M), and stroke by 34.3% (10.8M to 14.5M). Among White individuals, the prevalence of CV risk factors and disease is projected to decrease, whereas significant increases are projected in racial and ethnic minorities. CONCLUSIONS Large future increases in CV risk factors and CV disease prevalence are projected, disproportionately affecting racial and ethnic minorities. Future health policies and public health efforts should take these results into account to provide quality, affordable, and accessible health care.

Abstract
Importance Traditional models for predicting in-hospital mortality for patients with heart failure (HF) have used logistic regression and do not account for social determinants of health (SDOH). Objective To develop and validate novel machine learning (ML) models for HF mortality that incorporate SDOH. Design, Setting, and Participants This retrospective study used the data from the Get With The Guidelines-Heart Failure (GWTG-HF) registry to identify HF hospitalizations between January 1, 2010, and December 31, 2020. The study included patients with acute decompensated HF who were hospitalized at the GWTG-HF participating centers during the study period. Data analysis was performed January 6, 2021, to April 26, 2022. External validation was performed in the hospitalization cohort from the Atherosclerosis Risk in Communities (ARIC) study between 2005 and 2014. Main Outcomes and Measures Random forest-based ML approaches were used to develop race-specific and race-agnostic models for predicting in-hospital mortality. Performance was assessed using C index (discrimination), regression slopes for observed vs predicted mortality rates (calibration), and decision curves for prognostic utility. Results The training data set included 123 634 hospitalized patients with HF who were enrolled in the GWTG-HF registry (mean [SD] age, 71 [13] years; 58 356 [47.2%] female individuals; 65 278 [52.8%] male individuals. Patients were analyzed in 2 categories: Black (23 453 [19.0%]) and non-Black (2121 [2.1%] Asian; 91 154 [91.0%] White, and 6906 [6.9%] other race and ethnicity). The ML models demonstrated excellent performance in the internal testing subset (n = 82 420) (C statistic, 0.81 for Black patients and 0.82 for non-Black patients) and in the real-world-like cohort with less than 50% missingness on covariates (n = 553 506; C statistic, 0.74 for Black patients and 0.75 for non-Black patients). In the external validation cohort (ARIC registry; n = 1205 Black patients and 2264 non-Black patients), ML models demonstrated high discrimination and adequate calibration (C statistic, 0.79 and 0.80, respectively). Furthermore, the performance of the ML models was superior to the traditional GWTG-HF risk score model (C index, 0.69 for both race groups) and other rederived logistic regression models using race as a covariate. The performance of the ML models was identical using the race-specific and race-agnostic approaches in the GWTG-HF and external validation cohorts. In the GWTG-HF cohort, the addition of zip code-level SDOH parameters to the ML model with clinical covariates only was associated with better discrimination, prognostic utility (assessed using decision curves), and model reclassification metrics in Black patients (net reclassification improvement, 0.22 [95% CI, 0.14-0.30]; P < .001) but not in non-Black patients. Conclusions and Relevance ML models for HF mortality demonstrated superior performance to the traditional and rederived logistic regressions models using race as a covariate. The addition of SDOH parameters improved the prognostic utility of prediction models in Black patients but not non-Black patients in the GWTG-HF registry.

Abstract
Heart Failure (HF) remains a condition associated with high morbidity, mortality, and associated costs. Although the number of medical and device-based therapies available to treat HF are expanding at a remarkable rate, disparities in the risk for incident HF and treatments delivered to patients are also of growing concern. These disparities span across racial and ethnic groups, socioeconomic status, and apply across the spectrum of HF from Stage A to Stage D. The complexity of HF risk and treatment is further impacted by the number of patients who experience the downstream impact of social determinants of health. The purpose of this document is to highlight the known healthcare disparities that exist in the care of patients with HF, and to provide a context for how clinicians and researchers should assess both biologic and social determinants of HF risk in vulnerable populations. Furthermore, this document will provide a framework for future steps that can be utilized to help diminish inequalities in access and clinical outcomes over time, and offer solutions to help reduce disparities within HF care.

Abstract
Importance Despite bearing a disproportionate burden of heart failure (HF), Black and Hispanic individuals have been poorly represented in HF clinical trials. Underrepresentation in clinical trials limits the generalizability of the findings to these populations and may even introduce uncertainties and hesitancy when translating trial data to the care of people from underrepresented groups. The Heart Failure Collaboratory, a consortium of stakeholders convened to enhance HF therapeutic development, has been dedicated to improving recruitment strategies for patients from diverse and historically underrepresented groups. Observations Despite federal policies from the US Food and Drug Administration and National Institutes of Health aimed at improving trial representation, gaps in trial enrollment proportionate to the racial and ethnic composition of the HF population have persisted. Increasing trial globalization with limited US enrollment is a major driver of these patterns. Additional barriers to representative enrollment include inequities in care access, logistical issues in participation, restrictive enrollment criteria, and English language requirements. Conclusions and Relevance Strategies for improving diverse trial enrollment include methodical study design and site selection, diversification of research leadership and staff, broadening of eligibility criteria, community and patient engagement, and broad stakeholder commitment. In contemporary HF trials, diverse trial enrollment is not only feasible but can be efficiently achieved to improve the generalizability and translation of trial knowledge to clinical practice.

Abstract
ABSTRACT. Objective: Noncardiac chest pain is common and can cause distress, impair quality of life, and lead to recurrent evaluation. It is often multifactorial in etiology and influenced by psychological factors. The objective of this study was to describe the development, implementation, and preliminary feasibility of an 8-week multicomponent care management intervention. Methods: Participants with noncardiac chest pain were recruited from primary care clinics, ambulatory cardiac stress testing, and the emergency department (ED) at an urban academic hospital from March 2019 to November 2019. The care management team consisted of a nurse, cardiologist, and psychiatrist. Following a 1-time consultation visit with the cardiologist and nurse, evaluation and treatment recommendations were conveyed to the participant's primary care physician. The nurse completed 8 weekly phone calls with the participant to provide support, introduce therapeutic principles, and assist with care coordination under the supervision of a psychiatrist. Intervention feasibility was assessed on 7 domains. To examine preliminary efficacy, the number of ED visits was recorded, and participants completed pre-post measures of psychological health and health-related quality of life and Likert scales of chest pain symptom severity, frequency, and impact. Results: The intervention was developed and implemented in 3 patients who completed 100% of the consultation visits and a mean of 95.8% of study phone calls. There were no adverse events or ED visits. Mean scores for chest pain severity, chest pain frequency, chest pain impact, depression, anxiety, and somatization all improved. No other trends were observed. Conclusions: The findings suggest that a care management intervention may be feasible with potential to improve chest pain symptoms and psychological outcomes. A larger, randomized trial is needed to explore the efficacy of this intervention. Trial Registration: ClinicalTrials.gov identifier: NCT04904198.

Multiple Cardiac Biomarker Testing Among Patients With Acute Dyspnea From the ICON-RELOADED Study. J Card Fail 2021; 28:226-233. [PMID: 34634446 DOI: 10.1016/j.cardfail.2021.08.025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 08/24/2021] [Accepted: 08/25/2021] [Indexed: 01/23/2023]
Abstract
BACKGROUND Among patients with acute dyspnea, concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T, and insulin-like growth factor binding protein-7 predict cardiovascular outcomes and death. Understanding the optimal means to interpret these elevated biomarkers in patients presenting with acute dyspnea remains unknown. METHODS AND RESULTS Concentrations of NT-proBNP, high-sensitivity cardiac troponin T, and insulin-like growth factor binding protein-7 were analyzed in 1448 patients presenting with acute dyspnea from the prospective, multicenter International Collaborative of NT-proBNP-Re-evaluation of Acute Diagnostic Cut-Offs in the Emergency Department (ICON-RELOADED) Study. Eight biogroups were derived based upon patterns in biomarker elevation at presentation and compared for differences in baseline characteristics. Of 441 patients with elevations in all 3 biomarkers, 218 (49.4%) were diagnosed with acute heart failure (HF). The frequency of acute HF diagnosis in this biogroup was higher than those with elevations in 2 biomarkers (18.8%, 44 of 234), 1 biomarker (3.8%, 10 of 260), or no elevated biomarkers (0.4%, 2 of 513). The absolute number of elevated biomarkers on admission was prognostic of the composite end point of mortality and HF rehospitalization. In adjusted models, patients with one, 2, and 3 elevated biomarkers had 3.74 (95% confidence interval [CI], 1.26-11.1, P = .017), 12.3 (95% CI, 4.60-32.9, P < .001), and 12.6 (95% CI, 4.54-35.0, P < .001) fold increased risk of 180-day mortality or HF rehospitalization. CONCLUSIONS A multimarker panel of NT-proBNP, hsTnT, and IGBFP7 provides unique clinical, diagnostic, and prognostic information in patients presenting with acute dyspnea. Differences in the number of elevated biomarkers at presentation may allow for more efficient clinical risk stratification of short-term mortality and HF rehospitalization.

Abstract
Importance Women cardiologists receive lower salaries than men; however, it is unknown whether US Centers for Medicare & Medicaid Services (CMS) reimbursement also differs by gender and contributes to the lower salaries. Objective To determine whether gender differences exist in the reimbursements, charges, and reimbursement per charge from CMS. Design, Setting, and Participants This cross-sectional analysis used the CMS database to obtain 2016 reimbursement data for US cardiologists. These included reimbursements to cardiologists, charges submitted, and unique billing codes. Gender differences in reimbursement for evaluation and management and procedural charges from both inpatient and outpatient settings were also assessed. Analysis took place between April 2019 and December 2020. Main Outcomes and Measures Outcomes included median CMS payments received and median charges submitted in the inpatient and outpatient settings in 2016. Results In 2016, 17 524 cardiologists (2312 women [13%] and 15 212 men [87%]) received CMS payments in the inpatient setting, and 16 929 cardiologists (2151 women [13%] and 14 778 men [87%]) received CMS payments in the outpatient setting. Men received higher median payments in the inpatient (median [interquartile range], $62 897 [$30 904-$104 267] vs $45 288 [$21 371-$73 191]; P < .001) and outpatient (median [interquartile range], $91 053 [$34 820-$196 165] vs $51 975 [$15 622-$120 175]; P < .001) practice settings. Men submitted more median charges in the inpatient (median [interquartile range], 1190 [569-2093] charges vs 959 [569-2093] charges; P < .001) and outpatient settings (median [interquartile range], 1685 [644-3328] charges vs 870 [273-1988] charges; P < .001). In a multivariable-adjusted linear regression analysis, women received less CMS payments compared with men (log-scale β = -0.06; 95% CI, -0.11 to -0.02) after adjustment for number of charges, number of unique billing codes, complexity of patient panel, years since graduation of physicians, and physician subspecialty. Payment by billing codes, both inpatient and outpatient, did not differ by gender. Conclusions and Relevance There may be potential differences in CMS payments between men and women cardiologists, which appear to stem from gender differences in the number and types of charges submitted. The mechanisms behind these differences merit further research, both to understand why such gender differences exist and also to facilitate reductions in pay disparities.

Abstract
Background Racial and ethnic disparities contribute to differences in access and outcomes for patients undergoing heart transplantation. We evaluated contemporary outcomes for heart transplantation stratified by race and ethnicity as well as the new 2018 allocation system. Methods and Results Adult heart recipients from 2011 to 2020 were identified in the United Network for Organ Sharing database and stratified into 3 groups: Black, Hispanic, and White. We analyzed recipient and donor characteristics, and outcomes. Among 32 353 patients (25% Black, 9% Hispanic, 66% White), Black and Hispanic patients were younger, more likely to be women and have diabetes mellitus or renal disease (all, P<0.05). Over the study period, the proportion of Black and Hispanic patients listed for transplant increased: 21.7% to 28.2% (P=0.003) and 7.7% to 9.0% (P=0.002), respectively. Compared with White patients, Black patients were less likely to undergo transplantation (adjusted hazard ratio [aHR], 0.87; CI, 0.84-0.90; P<0.001), but had a higher risk of post-transplant death (aHR, 1.14; CI, 1.04-1.24; P=0.004). There were no differences in transplantation likelihood or post-transplant mortality between Hispanic and White patients. Following the allocation system change, transplantation rates increased for all groups (P<0.05). However, Black patients still had a lower likelihood of transplantation than White patients (aHR, 0.90; CI, 0.79-0.99; P=0.024). Conclusions Although the proportion of Black and Hispanic patients listed for cardiac transplantation have increased, significant disparities remain. Compared with White patients, Black patients were less likely to be transplanted, even with the new allocation system, and had a higher risk of post-transplantation death.

Abstract
OBJECTIVES The aim of this study was to evaluate the combined impact of race, ethnicity, and sex on in-hospital outcomes using data from the National Inpatient Sample. BACKGROUND Cardiogenic shock (CS) is a major cause of mortality following ST-segment elevation myocardial infarction (STEMI). Early revascularization reduces mortality in such patients. Mechanical circulatory support (MCS) devices are increasingly used to hemodynamically support patients during revascularization. Little is known about racial, ethnic, and sex disparities in patients with STEMI and CS. METHODS The National Inpatient Sample was queried from January 2006 to September 2015 for hospitalizations with STEMI and CS. The associations between sex, race, ethnicity, and outcomes were examined using complex-samples multivariate logistic or generalized linear model regressions. RESULTS Of 159,339 patients with STEMI and CS, 57,839 (36.3%) were women. In-hospital mortality was higher for all women (range 40% to 45.4%) compared with men (range 30.4% to 34.7%). Women (adjusted odds ratio [aOR]: 1.11; 95% confidence interval [CI]: 1.06 to 1.16; p < 0.001) as well as Black (aOR: 1.18; 95% CI: 1.04 to 1.34; p = 0.011) and Hispanic (aOR: 1.19; 95% CI: 1.06 to 1.33; p = 0.003) men had higher odds of in-hospital mortality compared with White men, with Hispanic women having the highest odds of in-hospital mortality (aOR: 1.46; 95% CI: 1.26 to 1.70; p < 0.001). Women were older (age: 69.8 years vs. 63.2 years), had more comorbidities, and underwent fewer invasive cardiac procedures, including revascularization, right heart catheterization, and MCS. CONCLUSIONS There are significant racial, ethnic, and sex differences in procedural utilization and clinical outcomes in patients with STEMI and CS. Women are less likely to undergo invasive cardiac procedures, including revascularization and MCS. Women as well as Black and Hispanic patients have a higher likelihood of death compared with White men.

Sodium-Glucose Co-Transporter 2 Inhibitors and Insights from Biomarker Measurement in Heart Failure Patients. Clin Chem 2021; 67:79-86.

Abstract
BACKGROUND Several large trials have demonstrated cardiac benefits in patients with and without established cardiovascular disease treated with sodium-glucose co-transporter 2 inhibitors (SGLT2i). Most recently, in patients with heart failure with reduced ejection fraction (HFrEF), the risk of worsening HF or cardiovascular death was lower among those who received dapagliflozin than among those who received placebo, regardless of the presence or absence of diabetes. Biomarkers may provide insight into understanding the mechanism of cardiovascular benefit observed in patients receiving SLGT2i. Several mechanisms have been proposed, including improvement in ventricular unloading due to the natriuretic effects, afterload reduction via reduction in blood pressure and improvement in vascular function, improvement in cardiac metabolism and bioenergetics, and reduction in cardiac fibrosis and necrosis, among others. CONTENT We discuss several animal and human studies on the effect of SGLT2i on various biomarkers. Modest reduction or blunting of rise over time in concentrations of atrial natriuretic peptide, B-type natriuretic peptide, and N-terminal pro B-type natriuretic peptide and reduction in high-sensitivity troponin has been observed in patients receiving SLGT2i. Concentrations of biomarkers such as sST2 and galectin-3 have been unchanged whereas inflammatory markers such as fibronectin 1, interleukin-6, matrix metalloproteinase 7, and tumor necrosis factor-1 are decreased with SGLT2i therapy. SUMMARY The effect of SLGT2i on various circulating biomarkers allows insight into the understanding of mechanisms of cardiovascular benefits with SGLT2i use. Further studies are needed to understand such mechanisms and to understand how biomarkers can be used for risk prediction and personalization of care in patients receiving SLGT2i.

Abstract
BACKGROUND The diagnosis of acute myocarditis typically requires either endomyocardial biopsy (which is invasive) or cardiovascular magnetic resonance imaging (which is not universally available). Additional approaches to diagnosis are desirable. We sought to identify a novel microRNA for the diagnosis of acute myocarditis. METHODS To identify a microRNA specific for myocarditis, we performed microRNA microarray analyses and quantitative polymerase-chain-reaction (qPCR) assays in sorted CD4+ T cells and type 17 helper T (Th17) cells after inducing experimental autoimmune myocarditis or myocardial infarction in mice. We also performed qPCR in samples from coxsackievirus-induced myocarditis in mice. We then identified the human homologue for this microRNA and compared its expression in plasma obtained from patients with acute myocarditis with the expression in various controls. RESULTS We confirmed that Th17 cells, which are characterized by the production of interleukin-17, are a characteristic feature of myocardial injury in the acute phase of myocarditis. The microRNA mmu-miR-721 was synthesized by Th17 cells and was present in the plasma of mice with acute autoimmune or viral myocarditis but not in those with acute myocardial infarction. The human homologue, designated hsa-miR-Chr8:96, was identified in four independent cohorts of patients with myocarditis. The area under the receiver-operating-characteristic curve for this novel microRNA for distinguishing patients with acute myocarditis from those with myocardial infarction was 0.927 (95% confidence interval, 0.879 to 0.975). The microRNA retained its diagnostic value in models after adjustment for age, sex, ejection fraction, and serum troponin level. CONCLUSIONS After identifying a novel microRNA in mice and humans with myocarditis, we found that the human homologue (hsa-miR-Chr8:96) could be used to distinguish patients with myocarditis from those with myocardial infarction.

Diagnostic and Prognostic Utilities of Insulin-Like Growth Factor Binding Protein-7 in Patients With Dyspnea. JACC-HEART FAILURE 2021; 8:415-422.

Abstract
OBJECTIVES This study examined whether insulin-like growth factor binding protein-7 (IGFBP7) would aid in the diagnosis and prognosis of acute heart failure (HF) beyond N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration. BACKGROUND IGFBP7 is associated with impaired ventricular relaxation and worse prognosis. METHODS The ICON-RELOADED (International Collaborative of NT-proBNP-Re-evaluation of Acute Diagnostic Cut-Offs in the Emergency Department) study was a prospective, multicenter clinical trial that enrolled subjects presenting with dyspnea. Six-month prognosis for death or repeat hospitalization was obtained. RESULTS Among 1,449 patients, 274 (18.9%) were diagnosed with acute HF. Those with IGFBP7 concentrations in the highest quartile were older, male, had hypertension and HF, had lower estimated glomerular filtration rate (eGFR) and lowest ejection fraction (41 ± 20%; all p < 0.001). Independent predictors of IGFBP7 were age, male sex, history of diabetes, history of HF, and eGFR. Median concentrations of NT-proBNP (2,844 ng/ml vs. 99 ng/ml) and IGFBP7 (146.1 ng/ml vs. 86.1 ng/ml) were higher in those with acute HF (both; p < 0.001). Addition of IGFBP7 to NT-proBNP concentrations improved discrimination, therefore increasing the area under the receiver operating curve for diagnosis of acute HF (from 0.91 to 0.94; p < 0.001 for differences). Addition of IGFBP7 to a complete model of independent predictors of acute HF improved model calibration. IGFBP7 significantly reclassified acute HF diagnosis beyond NT-proBNP (net reclassification index: +0.25). Higher log2-IGFBP7 concentrations in patients with acute HF predicted death or rehospitalization at 6 months (hazard ratio: 1.84 per log2-SD; 95% confidence interval: 1.30 to 2.61; p = 0.001). In Kaplan-Meier analyses, supramedian concentrations of IGFBP7 were associated with shorter event-free survival (log-rank: p < 0.001). CONCLUSIONS Among patients with acute dyspnea, concentrations of IGFBP7 add to NT-proBNP for diagnosis of acute HF and provide added prognostic utility for short-term risk.

Abstract
Background Due to the complexity and chronicity of heart failure, engaging yet simple patient self-management tools are needed. Objective This study aimed to assess the feasibility and patient engagement with a smartphone app designed for heart failure. Methods Patients with heart failure were randomized to intervention (smartphone with the Habits Heart App installed and Bluetooth-linked scale) or control (paper education material) groups. All intervention group patients were interviewed and monitored closely for app feasibility while receiving standard of care heart failure management by cardiologists. The Atlanta Heart Failure Knowledge Test, a quality of life survey (Kansas City Cardiomyopathy Questionnaire), and weight were assessed at baseline and final visits. Results Patients (N=28 patients; intervention: n=15; control: n=13) with heart failure (with reduced ejection fraction: 15/28, 54%; male: 20/28, 71%, female: 8/28, 29%; median age 63 years) were enrolled, and 82% of patients (N=23; intervention: 12/15, 80%; control: 11/13, 85%) completed both baseline and final visits (median follow up 60 days). In the intervention group, 2 out of the 12 patients who completed the study did not use the app after study onboarding due to illnesses and hospitalizations. Of the remaining 10 patients who used the app, 5 patients logged ≥1 interaction with the app per day on average, and 2 patients logged an interaction with the app every other day on average. The intervention group averaged 403 screen views (per patient) in 56 distinct sessions, 5-minute session durations, and 22 weight entries per patient. There was a direct correlation between duration of app use and improvement in heart failure knowledge (Atlanta Heart Failure Knowledge Test score; ρ=0.59, P=.04) and quality of life (Kansas City Cardiomyopathy Questionnaire score; ρ=0.63, P=.03). The correlation between app use and weight change was ρ=–0.40 (P=.19). Only 1 out of 11 patients in the control group retained education material by the follow-up visit. Conclusions The Habits Heart App with a Bluetooth-linked scale is a feasible way to engage patients in heart failure management, and barriers to app engagement were identified. A larger multicenter study may be warranted to evaluate the effectiveness of the app. Trial Registration ClinicalTrials.gov NCT03238729; http://clinicaltrials.gov/ct2/show/NCT03238729

Abstract
The COVID-19 pandemic underscored our healthcare system’s unpreparedness to manage an unprecedented pandemic. Heart failure (HF) physicians from 14 different academic and private practice centers share their systems’ challenges and innovations to care for patients with HF, heart transplantation, and patients on LVAD support during the COVID-19 pandemic. We discuss measures implemented to alleviate the fear in seeking care, ensure continued optimization of guideline directed medical therapy (GDMT), manage the heart transplant waiting list, continue essential outpatient monitoring of anticoagulation in LVAD patients and surveillance testing post-heart transplant, and prevent physician burnout. This collaborative work can build a foundation for better preparation in the face of future challenges.

Abstract
OBJECTIVE This study sought to determine whether patients with heart failure and reduced ejection fraction (HFrEF) with type 2 diabetes mellitus (T2DM) have similar reverse cardiac remodeling with sacubitril/valsartan as patients without T2DM. BACKGROUND Sacubitril/valsartan promotes reverse cardiac remodeling and improves outcomes in patients with HFrEF. Patients with HFrEF with T2DM have worse prognosis than those without T2DM. METHODS In this post hoc analysis of PROVE-HF (Prospective Study of Biomarkers, Symptom Improvement, and Ventricular Remodeling During Sacubitril/Valsartan Therapy for Heart Failure), we examined changes in N-terminal pro-b-type natriuretic peptide (NT-proBNP), measures of cardiac remodeling, and Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS) scores from baseline to 12 months following initiation of sacubitril/valsartan between patients with HFrEF with and without T2DM. Using latent growth curve modeling, we evaluated the longitudinal association between changes in NT-proBNP, left ventricular ejection fraction, and KCCQ-OS. RESULTS Among 794 patients enrolled, 361 (45.5%) had T2DM. NT-proBNP concentrations were modestly higher at baseline among patients with T2DM but were reduced after initiation of sacubitril/valsartan. Cross-sectional improvement was observed in left ventricular ejection fraction (T2DM: 28.3% at baseline and 37% at 12 months vs. non-T2DM: 28.1% at baseline and 38.3% at 12 months) and KCCQ-OS (T2DM: 71 at baseline and 83 at 12 months vs. non-T2DM: 76 at baseline and 88 at 12 months). Similar changes were also observed for other echocardiographic measures. In longitudinal analyses, the average NT-proBNP change was similar in patients with T2DM (-5.6% vs. -7.1% per 90-day interval; p = 0.64), whereas improvements in KCCQ-OS scores were slightly smaller (2.1 vs. 3.46 per 90-day interval; p = 0.07). CONCLUSIONS Sacubitril/valsartan favorably affects natriuretic peptide levels, reverse cardiac remodeling, and health status in patients with HFrEF with and without T2DM.

Abstract
BACKGROUND Treatment of heart failure with reduced ejection fraction (EF) may improve patient-reported health outcomes. OBJECTIVES The purpose of this study was to determine timing and magnitude of change in Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 scores following initiation of sacubitril/valsartan and interaction with change in amino-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations. METHODS From a single-arm, open-label study of patients initiated on sacubitril/valsartan, KCCQ-23 scores and NT-proBNP were obtained at baseline and follow-up through 12 months. Cross-sectional and longitudinal analyses evaluated magnitude and rate of change in KCCQ-23 scores and associations with NT-proBNP. Patient-level data from the randomized EVALUATE-HF study were used as historic controls. RESULTS The analysis cohort (n = 678, age 64.7 years, 71.5% men, EF 28.9%) had a baseline KCCQ-23 overall score (OS) of 65.6. Following sacubitril/valsartan initiation, the majority (n = 412; 60.8%) of participants experienced a rise in KCCQ-23 OS ≥10 points; 26.0% increased by ≥20 points. Comparable improvement in KCCQ-23 scores was seen in various subgroups. Change in KCCQ-23 OS was inversely associated with change in circulating NT-proBNP concentrations. Among a control group of patients in EVALUATE-HF, linear rate of change in KCCQ-12 OS/14-day interval in the enalapril arm was 0.37 points (p = 0.06), whereas in the sacubitril/valsartan arm, scores increased at a rate of 1.19 points (p < 0.001), nearly identical to this dataset (1.08 points; p < 0.001). CONCLUSIONS Treatment of heart failure with reduced EF with sacubitril/valsartan is associated with rapid and significant improvement in KCCQ-23 scores which was significantly related to change in NT-proBNP.

Abstract
OBJECTIVES This study sought to assess associations between longitudinal change in atrial natriuretic peptide (ANP) and reverse cardiac remodeling following initiation of sacubitril/valsartan in patients with heart failure with reduced ejection fraction (HFrEF). BACKGROUND Neprilysin inhibition results in an increase of several vasoactive peptides that may mediate the beneficial effects of sacubitril/valsartan, including ANP. METHODS In a prospective study of initiation and titration of sacubitril/valsartan in patients with HFrEF, blood was collected at scheduled time points into tubes containing protease inhibitors. This pre-specified exploratory analysis included patients in whom ANP was measured at baseline and serially through 12 months of treatment. RESULTS Among 144 participants (mean age: 64.5 years; left ventricular ejection fraction: 30.8%), following initiation of sacubitril/valsartan, there was an early and significant increase in ANP, with the majority of rise from 99 pg/ml at baseline to 156 pg/ml at day 14 (p < 0.001). There was a further trend toward a second increase from day 30 to day 45 (p = 0.07). At maximal rise, ANP had doubled. In longitudinal analyses, early rise in ANP was followed by a subsequent increase in urinary cycle guanosine monophosphate. Larger early increase in ANP was associated with larger later improvements in left ventricular ejection fraction and left atrial volume index (p < 0.001 for both). CONCLUSIONS Concentrations of ANP doubled after initiation of sacubitril/valsartan in patients with HFrEF. Larger early increases in ANP were associated with a greater magnitude of subsequent reverse cardiac remodeling.

Abstract
Aims We sought to determine sex‐based differences in biomarkers, self‐reported health status, and magnitude of longitudinal changes in measures of reverse cardiac remodelling among patients with heart failure with reduced ejection fraction (HFrEF, left ventricular ejection fraction ≤40%) treated with sacubitril/valsartan (S/V). Methods and results This was a subgroup analysis of patients initiated on S/V in the Prospective Study of Biomarkers, Symptom Improvement and Ventricular Remodeling During Entresto Therapy for Heart Failure (PROVE‐HF) study. There were 226 (28.5%) women in the study. Though women had lower baseline N‐terminal pro B‐type natriuretic peptide (NT‐proBNP), they had more rapid early reduction in the biomarker after initiation of S/V. Compared to men, women had lower average baseline Kansas City Cardiomyopathy Questionnaire (KCCQ)‐23 Total Symptom score (67.6 vs. 71.9; P = 0.003) but showed greater linear improvement (7.4 vs. 5.5 points; P < 0.001) and faster pace of KCCQ change (P < 0.001) over the course of the trial. Women and men demonstrated similar degrees of reverse left ventricular remodelling following S/V initiation; however, women did so earlier than men with more consistent changes. These results remained unchanged with adjustment for relevant covariates. Reduction in NT‐proBNP was associated with reverse cardiac remodelling in both women and men. Treatment with S/V was well tolerated in all. Conclusions In women with HFrEF, treatment with S/V was associated with significant NT‐proBNP reduction, health status improvement and reverse cardiac remodelling.

Abstract
Background Current noninvasive modalities to diagnose coronary artery disease (CAD) have several limitations. We sought to derive and externally validate a hs‐cTn (high‐sensitivity cardiac troponin)–based proteomic model to diagnose obstructive coronary artery disease. Methods and Results In a derivation cohort of 636 patients referred for coronary angiography, predictors of ≥70% coronary stenosis were identified from 6 clinical variables and 109 biomarkers. The final model was first internally validated on a separate cohort (n=275) and then externally validated on a cohort of 241 patients presenting to the ED with suspected acute myocardial infarction where ≥50% coronary stenosis was considered significant. The resulting model consisted of 3 clinical variables (male sex, age, and previous percutaneous coronary intervention) and 3 biomarkers (hs‐cTnI [high‐sensitivity cardiac troponin I], adiponectin, and kidney injury molecule‐1). In the internal validation cohort, the model yielded an area under the receiver operating characteristic curve of 0.85 for coronary stenosis ≥70% (P<0.001). At the optimal cutoff, we observed 80% sensitivity, 71% specificity, a positive predictive value of 83%, and negative predictive value of 66% for ≥70% stenosis. Partitioning the score result into 5 levels resulted in a positive predictive value of 97% and a negative predictive value of 89% at the highest and lowest levels, respectively. In the external validation cohort, the score performed similarly well. Notably, in patients who had myocardial infarction neither ruled in nor ruled out via hs‐cTnI testing (“indeterminate zone,” n=65), the score had an area under the receiver operating characteristic curve of 0.88 (P<0.001). Conclusions A model including hs‐cTnI can predict the presence of obstructive coronary artery disease with high accuracy including in those with indeterminate hs‐cTnI concentrations.

Abstract
IMPORTANCE Worldwide, the burden of heart failure has increased to an estimated 23 million people, and approximately 50% of cases are HF with reduced ejection fraction (HFrEF). OBSERVATIONS Heart failure is a clinical syndrome characterized by dyspnea or exertional limitation due to impairment of ventricular filling or ejection of blood or both. HFrEF occurs when the left ventricular ejection fraction (LVEF) is 40% or less and is accompanied by progressive left ventricular dilatation and adverse cardiac remodeling. Assessment for heart failure begins with obtaining a medical history and physical examination. Also central to diagnosis are elevated natriuretic peptides above age- and context-specific thresholds and identification of left ventricular systolic dysfunction with LVEF of 40% or less as measured by echocardiography. Treatment strategies include the use of diuretics to relieve symptoms and application of an expanding armamentarium of disease-modifying drug and device therapies. Unless there are specific contraindications, patients with HFrEF should be treated with a β-blocker and one of an angiotensin receptor-neprilysin inhibitor, angiotensin-converting enzyme inhibitor, or angiotensin receptor blocker as foundational therapy, with addition of a mineralocorticoid receptor antagonist in patients with persistent symptoms. Ivabradine and hydralazine/isosorbide dinitrate also have a role in the care of certain patients with HFrEF. More recently, sodium-glucose cotransporter 2 (SGLT2) inhibitors have further improved disease outcomes, significantly reducing cardiovascular and all-cause mortality irrespective of diabetes status, and vericiguat, a soluble guanylate cyclase stimulator, reduces heart failure hospitalization in high-risk patients with HFrEF. Device therapies may be beneficial in specific subpopulations, such as cardiac resynchronization therapy in patients with interventricular dyssynchrony, transcatheter mitral valve repair in patients with severe secondary mitral regurgitation, and implantable cardiac defibrillators in patients with more severe left ventricular dysfunction particularly of ischemic etiology. CONCLUSIONS AND RELEVANCE HFrEF is a major public health concern with substantial morbidity and mortality. The management of HFrEF has seen significant scientific breakthrough in recent decades, and the ability to alter the natural history of the disease has never been better. Recent developments include SGLT2 inhibitors, vericiguat, and transcatheter mitral valve repair, all of which incrementally improve prognosis beyond foundational neurohormonal therapies. Disease morbidity and mortality remain high, with a 5-year survival rate of 25% after hospitalization for HFrEF.

Abstract
Background:
Proteomics have already provided novel insights into the pathophysiology of heart failure (HF) with reduced ejection fraction. Previous studies have evaluated cross-sectional protein signatures of HF, but few have characterized proteomic changes following HF with reduced ejection fraction treatment with ARNI (angiotensin receptor/neprilysin inhibitor) therapy or left ventricular assist devices.
Methods:
In this retrospective omics study, we performed targeted proteomics (N=625) of whole blood sera from patients with American College of Cardiology/American Heart Association stage D (N=29) and stage C (N=12) HF using proximity extension assays. Samples were obtained before and after (median=82 days) left ventricular assist device implantation (stage D; primary analysis) and ARNI therapy initiation (stage C; matched reference). Oblique principal component analysis and point biserial correlations were used for feature extraction and selection; standardized mean differences were used to assess within and between-group differences; and enrichment analysis was used to generate and cluster Gene Ontology terms.
Results:
Core sets of proteins were identified for stage C (N=9 proteins) and stage D (N=18) HF; additionally, a core set of 5 shared HF proteins (NT-proBNP [N-terminal pro-B type natriuretic peptide], ESM [endothelial cell-specific molecule]-1, cathepsin L1, osteopontin, and MCSF-1) was also identified. For patients with stage D HF, moderate (δ, 0.40–0.60) and moderate-to-large (δ, 0.60–0.80) sized differences were observed in 8 of their 18 core proteins after left ventricular assist devices implantation. Additionally, specific protein groups reached concentration levels equivalent (
g
<0.10) to stage C HF after initiation on ARNI therapy.
Conclusions:
HF with reduced ejection fraction severity associates with distinct proteomic signatures that reflect underlying disease attributes; these core signatures may be useful for monitoring changes in cardiac function following initiation on ARNI or left ventricular assist device implantation.
