Abstract
Importance Concerns have arisen that renin-angiotensin system (RAS) blockers are less effective in Black patients than non-Black patients with heart failure and reduced ejection fraction (HFrEF). Objective To determine whether the effects of RAS blockers on cardiovascular outcomes differ between Black patients and non-Black patients with HFrEF. Data Sources MEDLINE and Embase databases through December 31, 2023. Study Selection Randomized trials investigating the effect of RAS blockers on cardiovascular outcomes in adults with HFrEF that enrolled Black and non-Black patients. Data Extraction and Synthesis Individual-participant data were extracted following Preferred Reporting Items for Systematic Reviews and Meta-analyses Independent Personal Data (PRISMA-IPD) reporting guidelines. Effects were estimated using a mixed-effects model using a 1-stage approach. Main Outcome and Measure The primary outcome was first hospitalization for HF or cardiovascular death. Results The primary analysis, based on the 3 placebo-controlled RAS inhibitor monotherapy trials, included 8825 patients (9.9% Black). Rates of death and hospitalization for HF were substantially higher in Black than non-Black patients. The hazard ratio (HR) for RAS blockade vs placebo for the primary composite was 0.84 (95% CI, 0.69-1.03) in Black patients and 0.73 (95% CI, 0.67-0.79) in non-Black patients (P for interaction = .14). The HR for first HF hospitalization was 0.89 (95% CI, 0.70-1.13) in Black patients and 0.62 (95% CI, 0.56-0.69) in non-Black patients (P for interaction = .006). Conversely, the corresponding HRs for cardiovascular death were 0.83 (95% CI, 0.65-1.07) and 0.84 (95% CI, 0.77-0.93), respectively (P for interaction = .99). For total hospitalizations for HF and cardiovascular deaths, the corresponding rate ratios were 0.82 (95% CI, 0.66-1.02) and 0.72 (95% CI, 0.66-0.80), respectively (P for interaction = .27). The supportive analyses including the 2 trials adding an angiotensin receptor blocker to background angiotensin-converting enzyme inhibitor treatment (n = 16 383) gave consistent findings. Conclusions and Relevance The mortality benefit from RAS blockade was similar in Black and non-Black patients. Despite the smaller relative risk reduction in hospitalization for HF with RAS blockade in Black patients, the absolute benefit in Black patients was comparable with non-Black patients because of the greater incidence of this outcome in Black patients.

Abstract
Heart failure is a serious threat to human health, with morbidity and mortality rates increasing despite the existence of multiple treatment options. Therefore, it is necessary to identify new therapeutic targets for this disease. Sacubitril/valsartan is a supramolecular sodium salt complex of the enkephalinase inhibitor prodrug sacubitril and the angiotensin receptor blocker valsartan. Its combined action increases endogenous natriuretic peptides while inhibiting the renin-angiotensin-aldosterone system and exerting cardioprotective effects. Clinical evidence suggests that sacubitril/valsartan is superior to conventional renin-angiotensin-aldosterone inhibitor therapy for patients with reduced ejection fraction heart failure who can tolerate angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. The therapy reduces the risk of heart failure hospitalization, cardiovascular mortality, and all-cause mortality and has a better safety and tolerability record. This review describes the potential pathophysiological mechanisms of cardiomyocyte injury amelioration by sacubitril/valsartan. We explore the protective effects of sacubitril/valsartan and outline the therapeutic value in patients with heart failure by summarizing the results of recent large clinical trials. Furthermore, a preliminary outlook shows that sacubitril/valsartan may be effective at treating other diseases, and provides some exploratory observations that lay the foundation for future studies on this drug.

Abstract
Objectives: Alzheimer's disease (AD) is an irreversible, progressive neurodegenerative disorder. The proportion of elderly individuals at risk for AD and cardiovascular problems increases by raising life expectancy. The present study was designed to investigate the effect of the sacubitril/valsartan combination compared to that of valsartan alone in a rat model of AD. Methods: 72 male adult Wistar rats were divided into seven groups; control untreated rats received saline, control valsartan-treated rats received valsartan orally, control sacubitril/valsartan treated rats received sacubitril/valsartan orally, model rats received aluminum chloride i.p., model valsartan treated rats received aluminum chloride i.p. and valsartan orally and model sacubitril/valsartan treated rats received aluminum chloride i.p. and sacubitril/valsartan combination orally. All previous treatments continued on a daily basis for 6 weeks. At the second, fourth, and sixth weeks of the experiment, behavioral changes were evaluated using the Morris water maze and novel object recognition tests, and systolic blood pressure was measured. In the end, rat brain malondialdehyde and amyloid-beta 1-42 levels were measured, and the isolated hippocampus was evaluated histopathologically. Results: Valsartan improved AD symptoms in the aluminum-induced rat model, while the sacubitril/valsartan combination significantly worsened all tested parameters in both control and model rats compared with untreated and valsartan-treated animals. Conclusion: Based on the current study's findings, valsartan did not increase the risk for AD development in control rats and improved AD symptoms in a rat model, while sacubitril/valsartan combination increased the risk of AD in control rats and worsened the condition in a rat model.

[PMID: 36620638 PMCID: PMC9815716 DOI: 10.3389/fcvm.2022.1058998] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 12/07/2022] [Indexed: 12/24/2022] Open
Abstract
Of the various medical therapies for heart failure (HF), sacubitril/valsartan is a first-in-class angiotensin receptor-neprilysin inhibitor that combines sacubitril, a pro-drug that is further metabolized to the neprilysin inhibitor sacubitrilat, and the angiotensin II type 1 receptor blocker valsartan. Inhibition of neprilysin and blockade of the angiotensin II type 1 receptor with sacubitril/valsartan increases vasoactive peptide levels, increasing vasodilation, natriuresis, and diuresis. Left ventricular ejection fraction (LVEF) is widely used to classify HF, to assist with clinical decision-making, for patient selection in HF clinical trials, and to optimize the benefits of sacubitril/valsartan in HF. However, as HF is a complex syndrome that occurs on a continuum of overlapping and changing phenotypes, patient classification based solely on LVEF becomes problematic. LVEF measurement can be imprecise, have low reproducibility, and often changes over time. LVEF may not accurately reflect inherent disease heterogeneity and complexity, and the addition of alternate criteria to LVEF may improve phenotyping of HF and help guide treatment choices. Sacubitril/valsartan may work, in part, by mechanisms that are not directly related to the LVEF. For example, this drug may exert antifibrotic and neurohumoral modulatory effects through inhibition or activation of several signaling pathways. In this review, we discuss markers of cardiac remodeling, fibrosis, systemic inflammation; activation of neurohormonal pathways, including the natriuretic system and the sympathetic nervous system; the presence of comorbidities; patient characteristics; hemodynamics; and HF signs and symptoms that may all be used to (1) better understand the mechanisms of action of sacubitril/valsartan and (2) help to identify subsets of patients who might benefit from treatment, regardless of LVEF.

Abstract
Cardiovascular diseases have become a major clinical burden globally. Heart failure is one of the diseases that commonly emanates from progressive uncontrolled hypertension. This gives rise to the need for a new treatment for the disease. Sacubitril/valsartan is a new drug combination that has been approved for patients with heart failure. This review aims to detail the mechanism of action for sacubitril/valsartan in cardiac remodeling, a cellular and molecular process that occurs during the development of heart failure. Accumulating evidence has unveiled the cardioprotective effects of sacubitril/valsartan on cellular and molecular modulation in cardiac remodeling, with recent large-scale randomized clinical trials confirming its supremacy over other traditional heart failure treatments. However, its molecular mechanism of action in cardiac remodeling remains obscure. Therefore, comprehending the molecular mechanism of action of sacubitril/valsartan could help future research to study the drug’s potential therapy to reduce the severity of heart failure.

Angiotensin Receptor Neprilysin Inhibition and Associated Outcomes by Race and Ethnicity in Patients With Heart Failure With Reduced Ejection Fraction: Data From CHAMP-HF. J Am Heart Assoc 2022; 11:e022889.

Abstract
Background There are limited data on the use of angiotensin receptor neprilysin inhibitors (ARNIs) in minority populations with heart failure (HF) with reduced ejection fraction. We used data from the CHAMP-HF (Change the Management of Patients With Heart Failure) registry to evaluate ARNI initiation and associated changes in health status and clinical outcomes across different races and ethnicities. Methods and Results CHAMP-HF was a prospective, observational registry of US outpatients with chronic HF with reduced ejection fraction. We compared patients starting ARNI with patients not starting ARNI using a propensity-matched analysis. Patients were grouped as Hispanic, non-Hispanic Black, non-Hispanic White, or non-Hispanic other individuals, where "non-Hispanic other" consists of all patients who did not identify as Hispanic, Black, or White. Health status was assessed using the 12-item Kansas City Cardiomyopathy Questionnaire. Outcomes were analyzed with multivariable models that included race and ethnicity, ARNI initiation, and an interaction term between race and ethnicity and ARNI initiation. Cox proportional hazards models were used for death/HF hospitalization, and multiple regression was used for change in Kansas City Cardiomyopathy Questionnaire score. The analysis included 1516 patients, with 758 patients in each group (ARNI and no ARNI). Changes in Kansas City Cardiomyopathy Questionnaire score after ARNI initiation were similar among all race and ethnicity groups (mean [SD], non-Hispanic White individuals, 3.5 [19.0]; non-Hispanic Black individuals, 2.0 [17.0]; non-Hispanic other individuals, 5.5 [20.3]; and Hispanic individuals, 3.2 [20.1]), with no statistically significant interaction between race and ethnicity and ARNI initiation (P=0.21). There was similarly no statistically significant interaction between race and ethnicity and ARNI initiation for HF hospitalization (P=0.82) or all-cause mortality (P=0.92). Conclusions In a large registry of outpatients with HF with reduced ejection fraction, the association between ARNI initiation and outcomes did not differ by race and ethnicity. These data support the use of ARNI therapy for chronic HF with reduced ejection fraction irrespective of race and ethnicity.

Abstract
This study aims to investigate the dosage pattern, efficacy, and safety of sacubitril/valsartan (Sac/Val) in Chinese heart failure with reduced ejection fraction (HFrEF) patients regarding real-world settings. Patients from 27 centers with a confirmed diagnosis of HFrEF and initiated Sac/Val treatment were enrolled. The primary objective was to evaluate the dosage pattern and change of heart failure status. In a final cohort of 983 patients, outpatient Sac/Val treatment demonstrated a similar beneficial effect in NT-proBNP and cardiac function. After initiating the treatment, overall and sub-population showed similar safety and efficacy. Patients who received a higher dose of Sac/Val (> 200 mg/d) demonstrated better improvement in LV function and reduction of NT-proBNP regardless of adjustment. Among Chinese HFrEF patients, Sac/Val showed a comparable reduction in NT-proBNP and improvement in cardiac function. Data further support guideline recommendations of Sac/Val in Chinese population. Optimal up-titration might provide further benefits. Further long-term and prognostic studies are needed.

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
AIMS The aim of this study was to determine the degree of short-term improvement in left ventricular ejection fraction (LVEF), haemodynamics, NT-proBNP and quality of life following initiation of sacubitril/valsartan in black patients when compared with white patients. METHODS This was a retrospective, observational, single-centre, hypothesis-generating study of patients with symptomatic heart failure and reduced ejection fraction (HFrEF) treated with guideline recommended therapy, who were transitioned from an ACE inhibitor (ACE-I) or angiotensin receptor blocker (ARB) to sacubitril/valsartan. RESULTS Our analysis included 83 patients (mean age 57 years) with echocardiography performed before and after transition from ACE-I/ARB to sacubitril/valsartan, after excluding patients with concomitant Cardiac resynchronization therapy implantation. Overall, sacubitril/valsartan was associated with LVEF improvement from 28.8% ± 0.7 to 32.0% ± 1.1% (P = 0.0002), but no reverse remodelling was observed. The association with LVEF improvement was only observed in white patients (n = 46, P = 0.0006), but not in black patients (n = 37, P = 0.1728), and appeared to be associated with reduced blood pressure (baseline vs. 2-week blood pressure 116.5 ± 13.9 vs. 109.4 ± 14.3 mmHg, respectively, in white patients, P = 0.0449). Fifteen patients (18.1%) became ineligible for primary prevention Implantable cardioverter defibrillator implantation. CONCLUSION Sacubitril/valsartan was associated with improved LVEF, NT-proBNP concentrations and quality of life in patients with symptomatic HFrEF on guideline recommended therapy. However, in our cohort, improvement of LVEF and quality of life might be attenuated in black patients, which warrants further investigation.

Abstract
Pediatric heart failure (HF) is an important clinical condition with high morbidity, mortality, and costs. Due to the heterogeneity in clinical presentation and etiologies, the development of therapeutic strategies is more challenging in children than adults. Most guidelines recommending drug therapy for pediatric HF are extrapolated from studies in adults. Unfortunately, even using all available treatment, progression to cardiac transplantation is common. The development of prospective clinical trials in the pediatric population has significant obstacles, including small sample sizes, slow recruitment rates, challenging endpoints, and high costs. However, progress is being made as evidenced by the recent introduction of ivabradine and of sacubitril/valsartan. In the last 5 years, new drugs have also been developed for HF with reduced ejection fraction (HFrEF) in adults. The use of well-designed prospective clinical trials will be fundamental in the evaluation of safety and efficacy of these new drugs on the pediatric population. The aim of this article is to review the clinical presentation and management of acute and chronic pediatric heart failure, focusing on systolic dysfunction in patients with biventricular circulation and a systemic left ventricle. We discuss the drugs recently approved for children and those emerging, or in use for adults with HFrEF.
