Factors Associated With Sacubitril/Valsartan Continuation and the Methods of Combining Heart Failure Medications in Patients With Heart Failure.

BACKGROUND: Sacubitril/valsartan (SV) is recommended for patients with heart failure (HF). In addition, a combination of 4 HF medications, including SV, is recommended in patients with HF with reduced ejection fraction (HFrEF). However, evidence on the characteristics of patients who could continue SV and its initiation methods is limited. OBJECTIVE: To investigate the factors associated with SV continuation and methods of combining HF medications. METHODS: This retrospective cohort study included HF patients who initiated with SV at our institution. The endpoint was SV continuation for 6 months after its initiation. Multivariate analysis was used to extract factors associated with SV continuation. The relationship between the methods of combining HF medications (renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or sodium-glucose cotransporter 2 inhibitors), including the number of HF medications, their combination patterns, and the timing of their initiation, and SV continuation was examined in patients with HFrEF. RESULTS: Of 186 eligible patients, 68.8% had HFrEF, and 79.0% continued SV for 6 months. Significant factors associated with SV continuation were albumin ≥ 3.5 g/dL (odds ratio, 4.81; 95% confidence interval, 2.19-10.59), body mass index (BMI) ≥ 18.5 kg/m2 (4.17; 1.10-15.85), and systolic blood pressure (SBP) ≥ 110 mmHg (2.66; 1.12-6.28). In patients with HFrEF, the proportion of HF medications not initiated simultaneously with SV was significantly higher in the continuation group than in the discontinuation group (67.3% vs 33.3%, P = 0.002). The number of HF medications and their combination patterns were not significantly associated with SV continuation. CONCLUSION AND RELEVANCE: Albumin, BMI, and SBP are useful indicators for selecting patients who are likely to continue SV. In addition, initiating only SV without simultaneously initiating other HF medications in patients with HFrEF may lead to SV continuation.

Subgroup disproportionality analysis of dementia-related adverse events with sacubitril/valsartan across geographical regions.

This study aimed to evaluate the association between sacubitril/valsartan and dementia-related adverse events (AEs) in geographical subpopulations using subgroup disproportionality analysis. Cases from the FDA adverse event reporting system involving patients aged 60 or older with sacubitril/valsartan or angiotensin receptor blockers (ARBs) were analyzed. The adjusted reporting odds ratios (RORs) for dementia-related AEs were calculated for each continent. A total of 61,518 AEs associated with sacubitril/valsartan or ARBs were identified. Among these, 1441 were dementia-related AEs. In Asia, Europe, and Africa, the reporting risk of dementia-related AEs associated with sacubitril/valsartan was lower compared to ARBs (adjusted ROR, 0.57 [95% CI 0.31-1.01]; adjusted ROR, 0.89 [95% CI 0.69-1.14]; adjusted ROR, 0.40 [95% CI 0.27-0.61], respectively). In Latin America and Oceania, the reporting risk of dementia-related AEs associated with sacubitril/valsartan was similar to that associated with ARBs (adjusted ROR, 1.04 [95% CI 0.75-1.44]; adjusted ROR, 1.02 [95% CI 0.31-3.37], respectively). On the contrary, in North America, the reporting risk associated with sacubitril/valsartan was higher compared to ARBs (adjusted ROR, 1.29 [95% CI 1.10-1.53]). Although the ROR value did not meet the criteria for signal detection, the significantly greater than 1 ROR observed in North America suggests that caution may be warranted regarding potential dementia-related adverse events associated with sacubitril/valsartan.

Sacubitril/valsartan reduces incident anaemia and iron therapy utilization in heart failure: The PARAGON-HF trial.

AIMS: Renin-angiotensin system inhibitors (RASi) have been shown to lower haemoglobin levels, potentially related to reductions in erythropoietin levels and haematopoiesis. We examined whether sacubitril/valsartan might attenuate this effect of RASi alone on incident anaemia in patients with heart failure (HF) with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF). METHODS AND RESULTS: PARAGON-HF was a global, multicentre randomized clinical trial of sacubitril/valsartan versus the RASi valsartan in patients with HF and left ventricular ejection fraction ≥45%. We evaluated haemoglobin trajectory and risks of incident anaemia and new iron therapy initiation during follow-up. Among 4795 participants, 1111 (23.2%) had anaemia at randomization and 5.6% were treated with iron at baseline. Over a median follow-up of 2.9 years, patients with anaemia were at significantly higher risk for total HF hospitalizations and cardiovascular death, compared with those without anaemia (21.6 vs. 11.5 per 100 patient-years; adjusted rate ratio 1.31; 95% confidence interval [CI] 1.12-1.54; p = 0.001). Sacubitril/valsartan slightly slowed the decline in haemoglobin levels by 0.1 g/dl (95% CI 0.0-0.2 g/dl; p = 0.005). Participants treated with sacubitril/valsartan were at significantly lower risk of developing anaemia (30.3% vs. 37.6%; hazard ratio [HR] 0.76; 95% CI 0.68-0.85; p < 0.001) and starting iron therapy (8.1% vs. 10.0%; HR 0.81; 95% CI 0.67-0.97; p = 0.026). Treatment effects of sacubitril/valsartan versus valsartan on total HF hospitalizations and cardiovascular death were consistent among patients across the haemoglobin spectrum (pinteraction = 0.60). CONCLUSIONS: Among patients with HFmrEF/HFpEF, treatment with sacubitril/valsartan resulted in modestly smaller declines in haemoglobin, lower rates of incident anaemia, and fewer new initiations of iron therapy compared with RASi.

Pseudo-nephropathy and hyper-excretion of urinary C-peptide: an overlooked adverse effect of an angiotensin receptor-neprilysin inhibitor (ARNI).

Sacubitril/valsartan, which is a combined angiotensin receptor-neprilysin inhibitor (ARNI), is used for the treatment of chronic heart failure and hypertension. Substrates of neprilysin are numerous, and the systemic effects of an ARNI remain to be determined. Increased urinary C-peptide (UCPR) and urinary albumin (UAlb) excretion has been reported with the use of an ARNI, but the mechanism is still unknown. We report an 84-year-old man with type 2 diabetes and hypertension. His UAlb and UCPR excretion and (to a lesser degree) the estimated glomerular filtration rate were increased after ARNI administration. They returned to basal levels after discontinuing ARNI administration. There was little or no change in glycemic control. Therefore, increased glomerular permeability and filtration could partially explain how neprilysin inhibition led to an elevation in UCPR excretion, in addition to other mechanisms, such as impairment of the renal ability to degrade C-peptide. Physicians must be cautious when interpreting the insulin secretion capability by UCPR and nephropathy by UAlb in ARNI-treated patients with diabetes.

Sacubitril/Valsartan Versus Enalapril in Chronic Chagas Cardiomyopathy: Rationale and Design of the PARACHUTE-HF Trial.

Chronic Chagas cardiomyopathy (CCC) has unique pathogenic and clinical features with worse prognosis than other causes of heart failure (HF), despite the fact that patients with CCC are often younger and have fewer comorbidities. Patients with CCC were not adequately represented in any of the landmark HF studies that support current treatment guidelines. PARACHUTE-HF (Prevention And Reduction of Adverse outcomes in Chagasic Heart failUre Trial Evaluation) is an active-controlled, randomized, phase IV trial designed to evaluate the effect of sacubitril/valsartan 200 mg twice daily vs enalapril 10 mg twice daily added to standard of care treatment for HF. The study aims to enroll approximately 900 patients with CCC and reduced ejection fraction at around 100 sites in Latin America. The primary outcome is a hierarchical composite of time from randomization to cardiovascular death, first HF hospitalization, or relative change from baseline to week 12 in NT-proBNP levels. PARACHUTE-HF will provide new data on the treatment of this high-risk population.

Empagliflozin combined with sacubitril/valsartan in hypertensive patients with heart failure: a retrospective study of efficacy and effect on blood pressure variability and cardiac function.

OBJECTIVE: To evaluate the efficacy of empagliflozin combined with sacubitril/valsartan in treating hypertensive patients with heart failure (HF), focusing on its effects on blood pressure variability (BPV) and cardiac function. METHODS: This retrospective study included 101 patients with hypertension and heart failure with reduced ejection fraction treated at Baoji High-Tech Hospital from October 2021 to October 2023. Patients were divided into two groups: an observation group (n=51), treated with both empagliflozin and sacubitril/valsartan, and a control group (n=50), treated with sacubitril/valsartan alone. We compared the therapeutic effects, BPV (including 24-hour, daytime, and nighttime systolic and diastolic BPV), cardiac function indicators, levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) before and after treatment, and the incidence of adverse reactions between the groups. Independent risk factors affecting treatment efficacy were also analyzed. RESULTS: The total effective rate of treatment in the observation group was significantly higher than in the control group (P<0.05). Both groups showed reductions in daytime and nighttime systolic and diastolic BPV after treatment, with the observation group displaying more pronounced improvements (all P<0.05). Enhancements in cardiac ultrasound measurements, NT-proBNP levels, and cTnI levels were more significant in the observation group compared to the control group post-treatment (both P<0.05). There was no significant difference in the incidence of adverse reactions during treatment between the two groups (P>0.05). Age and comorbid diabetes were identified as independent risk factors for poor prognosis, while treatment with empagliflozin combined with sacubitril/valsartan was a protective factor. CONCLUSION: Empagliflozin combined with sacubitril/valsartan significantly enhances treatment efficacy in hypertensive patients with heart failure, effectively improves cardiac function and BPV, and demonstrates good safety.

Association between treatment with sacubitril/valsartan and the risk of Alzheimer's disease: a clinical update.

Since 2014, sacubitril/valsartan (Entresto®) is widely prescribed for heart failure. Despite neprilysin inhibition's benefits in heart failure, concerns about potential amyloid-beta (Aß) accumulation and Alzheimer's disease (AD) risk have persisted. This narrative review, a decade post-approval, evaluates the risk of amyloid pathology and neurocognitive disorders in long-term sacubitril/valsartan use. Clinical trials, real-world studies, and pharmacovigilance data do not indicate an increased risk of cognitive decline. In patients treated with sacubitril/valsartan blood-based amyloid biomarkers show perturbations, while neuroimaging biomarkers reveal no significant increase in amyloid load. Despite a theoretical risk of amyloid accumulation and AD under treatment with sacubitril/valsartan, current clinical data appears reassuring, and there is no signal indicating an increased risk of cognitive decline, but a perturbation of amyloid blood-based biomarkers, which implies great caution when interpreting biomarkers in this context.

Impact of new drug releases on heart failure management and hospitalizations in France: A repeated cross-sectional study between 2014 and 2023.

Real-life data on the impact of sacubitril-valsartan and sodium-glucose cotransporter type 2 (SGLT-2) inhibitors on heart failure (HF) in France is lacking. Using French health insurance databases, we examined the ten-year evolution in HF medication use, focusing on SGLT-2 inhibitors and sacubitril/valsartan, and incidence of HF hospitalizations during the same period. We conducted a repeated cross-sectional study using medical-administrative data from French health insurance databases between 2014 and 2023. These included "OpenMedic" for outpatient medication reimbursements and "ScanSanté" for annual hospitalization data. Medications were classified using ATC codes, and hospitalizations were identified using ICD-10 codes. Statistical analyses encompassed annual rates of users and boxes dispensed for HF medications, along with HF, ischemic heart disease and ischemic stroke hospitalization rates. Prevalence of SGLT-2 inhibitors and sacubitril-valsartan use was also studied regionally, with direct standardization by age and sex, with the French population as the standard population. Between 2014 and 2023, HF drug use increased significantly, with beta-blockers and ACE inhibitors/ARBs leading in prevalence of use. ARNi and SGLT-2 inhibitors, introduced later, showed remarkable rises: +506% and +3766% in users since their market introduction, respectively. Meanwhile, HF hospitalizations slightly increased by +3.6% between 2016 and 2019, followed by a notable decline of -12.5% during 2019-2023, coinciding with the introduction of SGLT-2 inhibitors. In contrast, hospitalizations for ischemic heart disease rose by 11.6% over the period 2016-2019 and by +5.2% over the period 2019-2023, and hospitalizations for ischemic stroke rose by 8.2% over the period 2016-2019 and declined by -0.6% over the period 2019-2023. We observed regional disparities in SGLT-2 inhibitors use, with prevalence ranging from 0.9% in Bretagne to 1.5% in Hauts-de-France. The data suggests a temporal correlation between the increase in SGLT-2 inhibitors use and the decline in HF hospitalizations since 2019. More studies are needed to measure real life effectiveness of SGLT-2 inhibitors in heart failure.

Trajectories of Sacubitril/Valsartan Adherence Among Medicare Beneficiaries With Heart Failure.

Background: Sacubitril/valsartan, an angiotensin receptor/neprilysin inhibitor (ARNi), improves heart failure (HF) outcomes, yet real-world adherence patterns are not well understood. Objectives: The purpose of this study was to analyze longitudinal patterns of adherence to ARNis in patients with HF and to identify factors associated with adherence patterns. Methods: Using Medicare beneficiaries from 2015 to 2018, we included patients diagnosed with HF who initiated an ARNi. A group-based trajectory model was constructed to identify adherence patterns during follow-up. We used multivariable logistic regression to investigate factors associated with membership in each adherence trajectory group. Results: Among 9,475 eligible beneficiaries (age 77 ± 7 years, 34% female), we identified 5 distinct ARNi adherence trajectories, characterized as: immediate discontinuers, who discontinued treatment within the first 3 months (12%); early discontinuers, who discontinued treatment in months 4 to 7 (10%); late discontinuers, who discontinued treatment in months 7 to 10 (12%); intermittently adherent patients (12%); and consistently adherent patients (54%). The first 4 groups were collectively categorized as nonconsistent adherents. Living in a socioeconomically disadvantaged area, ie, a county with the top 20% of Area Deprivation Index (adjusted OR [aOR]: 1.12 [95% CI: 1.00-1.24]) and Black race (aOR: 1.36, [95% CI: 1.18-1.56]) were associated with a higher likelihood of being nonconsistently adherent. Receiving prescriptions from a cardiologist (aOR: 0.64 [95% CI: 0.57-0.73]) was associated with a lower likelihood of suboptimal ARNi adherence. Conclusions: Half of ARNi users were not consistently adherent to the drug in the first year after treatment initiation. There exist significant racial and socioeconomic inequities in longitudinal adherence to ARNi.

Safety Outcomes After Sacubitril/Valsartan Initiation in a Community Teaching Hospital: A Retrospective Observational Study.

BACKGROUND: Sacubitril/valsartan is one of the main foundational medications in heart failure (HF), and recent data show that it provides a mortality benefit in this patient population. Some of the main safety concerns associated with this drug class include hypotension, hyperkalemia, angioedema, and acute kidney injury (AKI). Other studies have focused on sacubitril/valsartan effects on blood glucose levels, which is a newer concept that has not been as researched. This study seeks to explore the safety of angiotensin receptor-neprilysin inhibitors (ARNi) when initiated in acute hospitalized patients, where data on tolerability will assist in patient selection and monitoring. The results of this study will help distinguish the HF population at a community teaching hospital and aid clinician decision-making. METHODS: This was a single-center, retrospective, observational review utilizing electronic health records. To be included in this study, patients had to be 18 years or older with an HF diagnosis and must have taken at least two doses of sacubitril/valsartan before discharge. Primary safety outcomes will include discontinuation of sacubitril/valsartan, incidence of angioedema, hyperkalemia, AKI, hypotension, and hypoglycemia. Secondary outcomes included hospital length of stay and 30-day readmission rate. RESULTS: Data were collected for a total of 227 patients. AKI was the most common primary safety adverse effect captured with 30 patients (14.02%), followed by hypotension in 20 patients (9.35%), and hyperkalemia in 19 patients (8.9%). Only one patient (0.44%) experienced both angioedema and hypotension, and it happened to be the same patient. Additionally, only one patient (0.47%) was found to be hypoglycemic. Sacubitril/valsartan was discontinued in 41 patients (18.1%), and 20 of those patients (8.8%) were restarted at a lower dose. Lastly, 63 patients (27.8%) were readmitted within 30 days of discharge. Patents that also had diabetes had worse safety outcomes and were associated with 30-day readmission.  Conclusions: This study of patients admitted with HF and started on sacubitril/valsartan found similar rates of efficacy and safety outcomes to previously published reports. However, the rate of hypoglycemia associated with sacubitril/valsartan was low in only one patient, and it was strongly associated with previous antidiabetic medication use. This differs from previously published reports and analyses on the association of sacubitril/valsartan and hypoglycemia. More research is needed for the argument that sacubitril/valsartan has an effect on glycemic outcomes. Patients with diabetes were found to have worse safety outcomes and a higher 30-day readmission. Providers should consider monitoring these patients closely and making sure that patients are on guideline-directed medication therapy before discharge. Other common safety events associated with sacubitril/valsartan were also seen in this population.

A real-world disproportionality analysis of sacubitril/valsartan: data mining of the FDA adverse event reporting system.

Purpose: Sacubitril/valsartan is extensively used in heart failure; however, there are few long-term safety studies of it in a wide range of populations. The aim of this study was to evaluate sacubitril/valsartan-induced adverse events (AEs) through data mining of the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). Methods: Reports in the FAERS from the third quarter of 2015 (FDA approval of sacubitril/valsartan) to the fourth quarter of 2023 were collected and analyzed. Disproportionality analyses, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and empirical Bayesian geometric mean (EBGM) algorithms were adopted in data mining to quantify signals of sacubitril/valsartan-associated AEs. Results: A total of 12,001,275 reports of sacubitril/valsartan as the "primary suspected (PS)" and 99,651 AEs induced by sacubitril/valsartan were identified. More males than females reported AEs (59.95% vs. 33.31%), with the highest number of reports in the 60-70 years age group (8.11%), and most AEs occurred < 7 days (14.13%) and ≥ 60 days (10.69%) after dosing. Sacubitril/valsartan-induced AE occurrence targeted 24 system organ classes (SOCs) and 294 preferred terms (PTs). Of these, 4 SOCs were strongly positive for all four algorithms, including cardiac disorders, vascular disorders, ear and labyrinth disorders, and respiratory, thoracic and mediastinal disorders. Among all PTs, consistent with the specification, hypotension (n = 10,078) had the highest number of reports, and dizziness, cough, peripheral swelling, blood potassium increased, and renal impairment were also reported in high numbers. Notably, this study also discovered a high frequency of side effects such as death, dyspnea, weight change, feeling abnormal, hearing loss, memory impairment, throat clearing, and diabetes mellitus. Conclusion: This study identified potential new AE signals and gained a more general understanding of the safety of sacubitril/valsartan, promoting its rational adoption in the cardiovascular system.

In-hospital initiation of angiotensin receptor-neprilysin inhibition in acute heart failure: the PREMIER trial.

BACKGROUND AND AIMS: The efficacy and safety of early sacubitril/valsartan (Sac/Val) initiation after acute heart failure (AHF) has not been demonstrated outside North America. The present study aimed to evaluate the effect of in-hospital Sac/Val therapy initiation after an AHF episode on N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in Japanese patients. METHODS: This was an investigator-initiated, multicentre, prospective, randomized, open-label, blinded-endpoint pragmatic trial. After haemodynamic stabilization within 7 days after hospitalization, eligible inpatients were allocated to switch from angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to Sac/Val (Sac/Val group) or to continue angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (control group). The primary efficacy endpoint was the 8-week proportional change in geometric means of NT-proBNP levels. RESULTS: A total of 400 patients were equally randomized, and 376 (median age 75 years, 31.9% women, de novo heart failure rate 55.6%, and median left ventricular ejection fraction 37%) were analysed. The per cent changes in NT-proBNP level geometric means at Weeks 4/8 were -35%/-45% (Sac/Val group) and -18%/-32% (control group), and their group ratio (Sac/Val vs. control) was 0.80 (95% confidence interval 0.68-0.94; P = .008) at Week 4 and 0.81 (95% confidence interval 0.68-0.95; P = .012) at Week 8, respectively. In the pre-specified subgroup analyses, the effects of Sac/Val were confined to patients with a left ventricular ejection fraction < 40% and were more evident in those in sinus rhythm and taking mineralocorticoid receptor antagonists. No adverse safety signal was evident. CONCLUSIONS: In-hospital Sac/Val therapy initiation in addition to contemporary recommended therapy triggered a greater NT-proBNP level reduction in Japanese patients hospitalized for AHF. These findings may expand the evidence on Sac/Val therapy in this clinical situation outside North America. CLINICAL TRIAL REGISTRATION: ClinicalTrial.gov (NCT05164653) and Japan Registry of Clinical Trials (jRCTs021210046).

Protein-Losing Enteropathy in the Failing Fontan: Treatment With Angiotensin Receptor Neprilysin Inhibitor.

Angiotensin receptor neprilysin inhibitor is the standard of care for systolic heart failure in adults. In addition, its use in adults with failing systemic right ventricles and diastolic heart failure is promising. This study reports our experience with this drug for protein-losing enteropathy secondary to Fontan failure in pediatrics.

Comparison of the Efficacy and Safety of Sacubitril/Valsartan and Angiotensin-Converting Enzyme Inhibitors/Angiotensin Receptor Blockers in Patients With Reduced Ejection Fraction Combined With Moderate-to-Severe Chronic Kidney Disease.

Background and Objectives: The efficacy and safety of a lower target dose of sacubitril/valsartan (angiotensin receptor neprilysin inhibitor [ARNI]) for treating heart failure with reduced ejection fraction (HFrEF) in Chinese patients with moderate-to-severe chronic kidney disease (CKD) remain unknown. We performed a retrospective study to compare the efficacy of ARNI with that of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) in patients with HFrEF and moderate-to-severe CKD. Methods: This retrospective study included 129 patients. An inverse probability of treatment weighting (IPTW) analysis was performed to compare the baseline characteristics and outcomes between the 2 groups. The incidence of death due to cardiovascular disease, rehospitalization due to heart failure after treatment, and improvement in cardiac function symptoms (New York Heart Association [NYHA]) were assessed after 12 months. Improvements of ejection fraction (EF), N-terminal pro-brain natriuretic peptide (NT-proBNP) level, left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD) were compared. Results: Compared with the ACEI/ARB group, the ARNI group, with 90.77% (59/65) in the lower target dose group, showed a lower rate of death due to cardiovascular disease (6.6% vs 0.9% after IPTW) and a lower incidence of rehospitalization (46.5% vs 30.4% after IPTW). NYHA class, estimated glomerular filtration rate, EF, NT-ProBNP levels, LVEDD, and LVESD improved in the ARNI group. None of the patients withdrew from treatment because of adverse drug reactions. Conclusion: Our study showed that ARNI resulted in a greater improvement in heart failure than ACEIs/ARBs in patients with HFrEF and moderate-to-severe CKD.

Detection of muscular system adverse reaction signals in sacubitril/valsartan treatment combined with statins.

Objective: To detect muscular system adverse reaction signals of sacubitril/valsartan treatment combined with statins (atorvastatin, rosuvastatin, simvastatin) to provide a reference for clinical administration. Methods: Multiplicative and additive models were used to mine the FDA's spontaneous reports database to detect signals of drug-drug interactions between sacubitril/valsartan and statins. SAS 9.4 software was used to conduct statistical tests for suspicious signals to determine whether the signals were statistically significant. Results: A total of 8,883,870 adverse reaction reports were analyzed. The combinations "sacubitril/valsartan - simvastatin - musculoskeletal muscle pain" had statistically significant correlation signals in both models (P < 0.05). The combination "sacubitril/valsartan - atorvastatin - myopathy" and "sacubitril/valsartan-simvastatin - myopathy" had statistically significant correlation signal in the multiplicative model (P < 0.05). Conclusion: Compared with a single drug, coadministration of sacubitril/valsartan with atorvastatin may increase safety risks to myopathy, with simvastatin may increase safety risks to the musculoskeletal pain and myopathy, which should be closely monitored in clinical practice.

Novel Therapies for the Treatment of Cardiovascular Disease.

Over the last decade, randomized clinical trials of several pharmacologic agents have demonstrated a reduction in cardiovascular mortality and other important secondary outcomes. Angiotensin-Neprilysin Inhibitors and Sodium-Glucose Co-transporter 2 inhibitors have now become pillars in the treatment of heart failure. Ivabradine is a negative chronotropic agent used as an adjunctive therapy in patients with heart failure. Two new hypertension therapies, zilebresiran and aprocitentan, are currently in investigational stages. Finally, mavacamten has emerged as a pharmacologic treatment for hypertrophic obstructive cardiomyopathy. Practitioners must be familiar with the indications and side effects of newer therapies as they are now frequently prescribed.

Sacubitril/valsartan alleviates sepsis-induced myocardial injury in rats via dual angiotensin receptor-neprilysin inhibition and modulation of inflammasome/caspase 1/IL1ß pathway.

Sepsis is a life-threatening situation that ultimately affects cardiac function, leading to cardiomyopathy and myocardial injury as a result of uncontrolled response to infection.Till now, there is limited effective treatment to rescue those cases. Thus, novel therapeutic strategies should be identified to achieve better outcomes for septic patients. For the first time, we aimed to evaluate the effect of sacubitril/valsartan (Sac/Val) on sepsis-induced cardiac injury. Wistar male adult albino rats were randomly divided into four groups; Group I received the vehicle; Group II was given the vehicle plus 1 ml saline containing viable Escherichia coli (E. coli) (2.1 × 109 cfu) by intraperitoneal (i.p.) injection on the 1st and 2nd days; Group III received i.p. injection as group II plus oral administration of Sac/Val (30 mg/kg/day) and Nitro- ω-L-arginine (L-NNA) (25 mg/kg/day) for 7 days. Group IV was administered i.p. injection as group II plus oral administration of Sac/Val (30 mg/kg/day) for 7 days. Our data (n = 10) revealed successful induction of sepsis as it showed a significant increase in the measured cardiac enzymes, malondialdehyde (MDA), angiotensin II (Ang II), neprilysin, inflammasome, caspase 1, interleukin (IL)1ß, and caspase 3 with cardiac histopathological changes, but there was a significant decrease in the antioxidants and blood pressure (BP). Co-administration of Sac/Val could obviously improve these changes. Interestingly, L-NNA given group showed a decrease in the cardioprotective effect of Sac/Val. Sac/Val could ameliorate sepsis induced cardiac damage via inhibition of Ang II and neprilysin with anti-inflammatory, anti-oxidant and anti-apoptotic properties.

Acute changes in kidney function and outcomes following an acute myocardial infarction: Insights from PARADISE-MI.

AIMS: Pharmacologic blockade of neurohormonal pathways in patients with acute myocardial infarction (MI) can result in acute changes in biomarkers of kidney function. We evaluated the effect of sacubitril/valsartan versus ramipril on initial changes in serum creatinine and the association of these changes with longer-term outcomes among participants in PARADISE-MI. METHODS AND RESULTS: In this randomized, double-blind, active-controlled, event-driven trial, 5661 patients with an acute MI were assigned to receive sacubitril/valsartan or ramipril, with no run-in. The frequency of an initial pre-specified increase in serum creatinine (≥26.5 or ≥44 µmol/L) from baseline to week 1 was compared between arms. Multivariable Cox regression models were fit to examine the association of acute changes in serum creatinine with the primary cardiovascular composite outcome (cardiovascular death, first heart failure hospitalization, or outpatient heart failure), all-cause mortality, and longer-term changes in estimated glomerular filtration rate (eGFR). An initial increase in serum creatinine ≥26.5 µmol/L occurred in 155 of 2604 (6.0%) patients assigned to sacubitril/valsartan and 120 of 2603 (4.6%) patients assigned to ramipril (odds ratio [OR] 1.32; 95% confidence interval [CI] 1.03-1.68). The corresponding numbers for an increase ≥44 µmol/L were 57 (2.2%) and 42 (1.6%), respectively (OR 1.37; 95% CI 0.92-2.05). A higher odds of increased serum creatinine ≥26.5 and ≥44 µmol/L for sacubitril/valsartan versus ramipril appeared to be restricted to patients who had a greater decline in systolic blood pressure over the same period (p-interaction = 0.05 and 0.001, respectively). In multivariable analyses, neither an acute increase in serum creatinine ≥26.5 or ≥44 µmol/L was associated with a higher risk of cardiovascular outcomes, all-cause mortality, or differences in longer-term eGFR slope. Findings were similar across the randomized treatment arms (p-interaction >0.6 for all). CONCLUSIONS: Following acute MI, patients assigned to sacubitril/valsartan had a higher frequency of initial increases in serum creatinine at 1 week, compared with ramipril. In adjusted models, initial increases in serum creatinine with either treatment were not associated with adverse cardiovascular outcomes or changes in longer-term kidney function.

Effects of sacubitril-valsartan on aging-related cardiac dysfunction.

Heart failure (HF) remains a huge medical burden worldwide, with aging representing a major risk factor. Here, we report the effects of sacubitril/valsartan, an approved drug for HF with reduced EF, in an experimental model of aging-related HF with preserved ejection fraction (HFpEF). Eighteen-month-old female Fisher 344 rats were treated for 12 weeks with sacubitril/valsartan (60 mg/kg/day) or with valsartan (30 mg/kg/day). Three-month-old rats were used as control. No differential action of sacubitril/valsartan versus valsartan alone, either positive or negative, was observed. The positive effects of both sacubitril/valsartan and valsartan on cardiac hypertrophy was evidenced by a significant reduction of wall thickness and myocyte cross-sectional area. Contrarily, myocardial fibrosis in aging heart was not reduced by any treatment. Doppler echocardiography and left ventricular catheterization evidenced diastolic dysfunction in untreated and treated old rats. In aging rats, both classical and non-classical renin-angiotensin-aldosterone system (RAAS) were modulated. In particular, with respect to untreated animals, both sacubitril/valsartan and valsartan showed a partial restoration of cardioprotective non-classical RAAS. In conclusion, this study evidenced the favorable effects, by both treatments, on age-related cardiac hypertrophy. The attenuation of cardiomyocyte size and hypertrophic response may be linked to a shift towards cardioprotective RAAS signaling. However, diastolic dysfunction and cardiac fibrosis persisted despite of treatment and were accompanied by myocardial inflammation, endothelial activation, and oxidative stress.
