Global use of angiotensin receptor neprilysin inhibitor in heart failure and reduced, below normal and supranormal ejection fraction.

BACKGROUND: The global use of angiotensin receptor neprilysin inhibitor (ARNI) in clinical practice, especially in patients with heart failure and below-normal ejection fraction (HFbnEF), has not been thoroughly evaluated. We aimed to investigate the characteristics, outcomes, and adverse events in patients treated with ARNI for HF with reduced (HFrEF), below-normal (HFbnEF), and supranormal left ventricular EF (HFsnEF). METHODS: This observational study analyzed data from the electronic healthcare records (EHR) of patients with HF treated with ARNI between 2015 and 2022 in North and South America, Europe, the Middle East, Africa, and Asia-Pacific. Based on the left ventricular EF, patients were categorized as HFrEF (< 40%), HFbnEF (40-60%), and HFsnEF (> 60%). Mortality and the incidence of adverse events were investigated. RESULTS: Of the 11,141 patients analyzed, HFrEF, HFbnEF and HFsnEF accounted for 74%, 22%, and 4%, respectively. Patients with a higher EF were more likely to be older, female, and obese. Hypertension and atrial fibrillation were the most common in HFsnEF. Systolic blood pressure was lower and natriuretic peptide levels were higher in the lower EF groups. Mortality was lowest in HFbnEF (7.7 per 100 patient-years follow-up in HFrEF, 5.8 in HFmrEF, and 6.0 in HFsnEF). Similarly, hypotension and acute kidney injury were the least frequent in HFbnEF. Incidence of elevated serum potassium levels was similar between the groups. CONCLUSIONS: In this analysis of large-scale EHR, ARNI was mainly used in HFrEF and HFbnEF, consistent with previous randomized trials and pooled analyses. Adverse events were less common in HFbnEF.

Qualitative Evaluation to Understand Barriers and Facilitators to Prescribing Angiotensin Receptor-Neprilysin Inhibitors (ARNi) and Sodium-Glucose Cotransporter Inhibitors (SGLT2i) in Patients with Heart Failure with Reduced Ejection Fraction (HFrEF).

BACKGROUND: Despite sodium-glucose cotransporter-2 inhibitors (SGLT2i) and angiotensin receptor/neprilysin inhibitors (ARNi) being cost-effective evidenced-based therapies for the management of Heart Failure with Reduced Ejection Fraction (HFrEF), research shows that less than 30% of patients with HFrEF are prescribed these agents. OBJECTIVE: This study aimed to understand clinician-perceived barriers and facilitators to prescribing ARNi and SGLT2i in patients with HFrEF. METHODS: We conducted virtual and in-person semi-structured interviews in a large integrated healthcare delivery system in the United States. Twenty cardiology clinicians managing patients with HFrEF were recruited using purposeful sampling to target providers across professions and practice sites. The interview guide was developed based on a literature review and insights from a practicing cardiologist. It inquired about perceived prescribing behaviors, focusing on factors affecting the use of ARNi and SGLT2i. We identified key themes using rapid qualitative analysis. RESULTS: Twenty clinicians were interviewed: 13 physicians, five advanced practitioners, and two clinic-based pharmacists. Eighteen interviews were analyzed; we excluded two as the clinicians interviewed did not meet the inclusion criteria. Three major themes were identified: 1) clinician-reported prescribing patterns don't always align with the American College of Cardiology/American Heart Association guidelines for the use of SGLT2i and ARNi due to clinical inertia, lack of familiarity, knowledge, and comfort with use, and concerns over polypharmacy or adverse events, 2) clinician-perceived and actual out-of-pocket cost reduced prescribing of ARNi or SGLT2i to patients, exacerbated by a lack of visibility into patients' prescription coverage, denials of coverage by insurance, and navigating prior authorization related workflows, and 3) incorporation of a clinic-based pharmacist increased the prescribing of these medications. CONCLUSIONS: Increasing cost transparency, implementing interventions to overcome clinical inertia and cost hurdles, and increasing clinic-based pharmacist support may improve evidenced-based prescribing in patients with HFrEF, especially for comparatively novel classes such as ARNi and SGLT2i.

Use and Benefit of Sacubitril/Valsartan in Elderly Patients with Heart Failure with Reduced Ejection Fraction.

Background: Heart failure (HF) is a highly prevalent syndrome in elderly subjects. Currently, multiple drugs have shown clinical benefits in patients with HF and reduced ejection fraction (HFrEF). However, evidence is scarce in elderly patients (beyond 75 years old), even more so for the latest drugs, such as angiotensin receptor-neprilysin inhibitors (ARNIs). This study aims to evaluate the use and benefits of ARNIs in elderly patients with HFrEF. Methods: A prospective observational cohort study was designed. Patients with left ventricular systolic dysfunction (defined by left ventricular ejection fraction [LVEF] < 40%) and age ≥ 75 years from January 2016 to December 2020 were prospectively included. Patients with an indication for ARNIs at inclusion or throughout follow-up were selected. Clinical, electrocardiographic and echocardiographic variables were collected. Results: A total of 616 patients were included, 34.4% of them female, with a mean age of 83.3 years, mean LVEF of 28.5% and ischemic etiology in 53.9% of patients. Only 14.3% of patients were taking ARNIs. After a mean follow-up of 34 months, 50.2% of patients died, and 62.2% had a cardiac event (total mortality or hospital admission due to HF). Multivariate Cox regression analysis showed that the use of ARNIs was independently and significantly associated with lower rates of mortality [HR 0.36 (95% CI 0.21-0.61)], with similar results in relation to all-cause mortality in a propensity-score-matched analysis [HR 0.33 (95% CI 0.19-0.57)]. Conclusions: We observed an important underuse of ARNIs in a cohort of elderly HFrEF patients, in which treatment with ARNIs was associated with a significant reduction in mortality. Greater implementation of clinical practice guidelines in this group of patients could improve their prognosis.

Modern heart failure treatment is superior to conventional treatment across the left ventricular ejection spectrum: real-life data from the Swedish Heart Failure Registry 2013-2020.

OBJECTIVES: This study is aimed to compare the effectiveness of modern therapy including angiotensin receptor-neprilysin inhibitor (ARNI) and sodium-glucose cotransporter 2 inhibitors (SGLT2i) with conventional heart failure treatment in the real world. BACKGROUND: Since ARNI and SGLT2i were introduced to treat heart failure (HF), its therapeutic regimen has modernized from previous treatment with beta-blocker (BB) and angiotensin-converting enzyme inhibitor (ACEi)/angiotensin II receptor blocker (ARB) with mineralocorticoid receptor antagonist (MRA) as added-on in HF with reduced ejection fraction (HFrEF). However, a comparison between conventional and modern treatment strategies with drugs in combination has not been performed. METHODS: This observational study (2013-2020), using the Swedish HF Registry, involved 20,849 HF patients. Patients received either conventional (BB, ACEi/ARB, with/without MRA, n = 20,140) or modern (BB, ACEi/ARB, MRA, SGLT2i or BB, ARNI, MRA with/without SGLT2i, n = 709) treatment at the index visit. The endpoints were all-cause and cardiovascular (CV) mortality. RESULTS: Modern HF therapy was associated with a significant 28% reduction in all-cause mortality (adjusted HR [aHR], 0.72 (0.54-0.96); p = 0.024) and a significant 62% reduction in CV mortality (aHR, 0.38 (0.21-0.68); p = 0.0013) compared to conventional HF treatment. Similar results emerged in a sensitivity analysis using propensity score matching. The interaction analyses did not reveal any trends for EF (< 40% and ≥ 40%), sex, age (< 70 and ≥ 70 years), eGFR (< 60 and ≥ 60 ml/min/1.73 m2), and etiology of HF subgroups. CONCLUSION: In this nationwide study, modern HF therapy was associated with significantly reduced all-cause and CV mortality, regardless of EF, sex, age, eGFR, and etiology of HF.

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.

Post-acute CoVid-19 syndrome (PACS) linked cardiovascular symptoms.

Officials have marked the end of the CoVid-19 pandemic, yet we continue to learn more about the SARS-CoV2 virus itself and its lasting multidimensional effects after acute infection. Long COVID, or the post-acute CoViD-19 syndrome (PACS), manifests as a wide range of prolonged physical, mental, and emotional symptoms over at least 1 to 12 months after SARS-CoV2 infection. Here, we describe certain pervasive clinical consequences of PACS on the cardiovascular system, and insight on the potentially improved prognoses in heart failure patients.

The contemporary role of sodium-glucose co-transporter 2 inhibitor (SGLT2i) and angiotensin receptor-neprilysin inhibitor (ARNI) in the management of heart failure: State-of-the-art review.

Novel therapies for heart failure with reduced ejection fraction (HFrEF) are angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose co-transporter 2 inhibitor (SGLT2i), etc. The purpose of this review is to determine the effects of ARNI and SGLT2i in heart failure (HF), compare the impact of SGLT2i with ARNI, and finally evaluate the current data regarding the combination of these two drugs in HF. Various trials on the respective medications have shown some significant reduction in all-cause mortality and cardiovascular (CV) death. The combination of these drugs has shown more CV benefits than monotherapy. There is emerging data about these two drugs in patients with heart failure with preserved ejection fraction (HFpEF). At present, there are less head-to-head comparison trials of these two drugs. This review provides insights on the current evidence, comparative efficacy, and combination therapy of ARNI and SGLT2i in managing HF, focussing on HFrEF and HFpEF.

Angiotensin Receptor-Neprilysin Inhibitor Is Associated With Improved Cardiac Autonomic Function in Heart Failure.

BACKGROUND: Heart failure with reduced ejection fraction is associated with potentially deleterious imbalance of the cardiac autonomic nervous system. Sacubitril/valsartan (angiotensin receptor-neprilysin inhibitor [ARNI]) reduces cardiovascular mortality and hospitalization for heart failure with reduced ejection fraction. Whether ARNI affects the cardiac autonomic nervous system has not been studied. METHODS AND RESULTS: This investigator-initiated, prospective, single-center cohort study compared heart rate (HR) variability, HR, deceleration capacity, and periodic repolarization dynamics as noninvasive measures of the cardiac autonomic nervous system before and after initiation of ARNI therapy. Patients underwent standardized 12-lead Holter-ECG, echocardiography and laboratory testing before and 3 months after start of therapy. End points were changes in HR variability (SD of normal-to-normal intervals, mean square of differences between consecutive R-R intervals), HR, deceleration capacity, and periodic repolarization dynamics as well as ventricular function and NT-proBNP (N-terminal pro-B-type natriuretic peptide). Of 63 patients with heart failure with reduced ejection fraction enrolled, 48 (76.2%) patients were still on ARNI at follow-up. SD of normal-to-normal intervals increased from 25 to 36 milliseconds (P<0.001), mean square of differences between consecutive R-R intervals increased from 12 to 19 milliseconds (P<0.001), HR decreased from 73±9 bpm to 67±4 bpm, (P<0.001), and deceleration capacity increased from 2.1 to 4.4 milliseconds (P<0.001). A trend for periodic repolarization dynamics reduction was observed (5.6 deg2 versus 4.7 deg2, P=0.09). Autonomic changes were accompanied by increased left ventricular ejection fraction (29±6% versus 40±8%, P<0.001) and reduced NT-proBNP (3548 versus 685 ng/L, P<0.001). Correlation analysis showed a significant relationship between volume-unloading (as evidenced by NT-proBNP reduction) and autonomic improvement. CONCLUSIONS: Three months of ARNI therapy resulted in a significant increase in cardiac parasympathetic tone. The improvement in autonomic properties may be mediated by "volume unloading" and likely contributes to the beneficial effects of ARNI in heart failure with reduced ejection fraction.

Predictors of Hypotension After Angiotensin Receptor-Neprilysin Inhibitor Administration in Patients with Heart Failure.

Angiotensin receptor-neprilysin inhibitors (ARNI) are effective against heart failure (HF) with reduced ejection fraction, but hypotension is a significant complication. Predictors of ARNI-associated hypotension remain unclear. This study aimed to determine predictors of hypotension after administering an ARNI to patients with HF accompanied by ARNI.This retrospective multicenter observational study analyzed data from 138 consecutive patients with HF treated with an ARNI between August 2020 and July 2021. Hypotension attributed to an ARNI after treatment was defined as (A) systolic blood pressure (SBP) below the 1st quartile ≤ 25 mmHg, and as (B) absolute SBP ≤ 103 mmHg. SBP was measured at baseline, after ARNI treatment, at first follow-up as outpatients and on day 7 for inpatients. Presence of atrial fibrillation, and greater BUN/Cr ratio, and SBP at baseline were significant independent predictors for hypotension after ARNI administration on multivariate analyses. Among 43 patients with AF, fine f-waves on electrocardiograms were significantly more prevalent in the hypotensive group.A robust reduction in blood pressure after ARNI administration is associated with AF and elevated BUN/Cr. This highlights the need for caution when administering ARNI to patients with HF.

Effects of angiotensin receptor-neprilysin inhibitor on ketone body metabolism in pre-heart failure/heart failure patients.

Recently, a mild elevation of the blood ketone levels was found to exert multifaceted cardioprotective effects. To investigate the effect of angiotensin receptor neprilysin inhibitors (ARNIs) on the blood ketone body levels, 46 stable pre-heart failure (HF)/HF patients were studied, including 23 who switched from angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) to ARNIs (ARNI group) and 23 who continued treatment with ACE inhibitors or ARBs (control group). At baseline, there were no significant differences in the total ketone body (TKB) levels between the two groups. Three months later, the TKB levels in the ARNI group were higher than the baseline values (baseline to 3 months: 71 [51, 122] to 92 [61, 270] µmol/L, P < 0.01). In the control group, no significant change was observed between the baseline and 3 months later. A multiple regression analysis demonstrated that the initiation of ARNI and an increase in the blood non-esterified fatty acid (NEFA) levels at 3 months increased the percentage changes in the TKB levels from baseline to 3 months (%ΔTKB level) (initiation of ARNI: P = 0.017, NEFA level at 3 months: P < 0.001). These results indicate that ARNI administration induces a mild elevation of the blood TKB levels in pre-HF/HF patients.

Unlocking the Potential: Angiotensin Receptor Neprilysin and Sodium Glucose Co-Transporter 2 Inhibitors for Right Ventricle Dysfunction in Heart Failure.

This review article examines the mechanism of action of Angiotensin Receptor-Neprilysin Inhibitors (ARNIs) and Sodium-Glucose Co-Transporter 2 Inhibitors (SGLT2is) in managing chronic right ventricular (RV) dysfunction. Despite advancements in heart failure (HF) treatment, RV dysfunction remains a significant contributor to morbidity and mortality. This article explores the The article explores the impact of ARNIs and SGLT2is on RV function based on clinical and preclinical evidence, and the potential benefits of combined therapy. It highlights the need for further research to optimize patient outcomes and suggests that RV function should be considered in future clinical trials as part of risk stratification for HF therapies. This review underscores the importance of the early initiation of ARNIs and SGLT2is as per guideline-directed medical therapy for eligible HFrEF and HFpEF patients to improve co-existing RV dysfunction.

Guideline-Optimised Treatment in Heart Failure-Do Higher Doses Reduce Systemic Inflammation More Significantly?

Background: Chronic inflammation is a constant phenomenon which accompanies the heart failure pathophysiology. In all phenotypes of heart failure, irrespective of the ejection fraction, there is a permanent low-grade activation and synthesis of proinflammatory cytokines. Many classes of anti-remodelling medication used in the treatment of chronic heart failure have been postulated to have an anti-inflammatory effect. Methods: This retrospective study enrolled 220 patients and focused on evaluating the effect of the most used active substances from these classes in reducing the level of inflammatory biomarkers (C reactive protein, erythrocyte sedimentation rate and fibrinogen) after initiation or up-titration. Our research is evaluating if this anti-inflammatory effect intensifies while raising the dose. The evaluation was performed at two visits with an interval between them of 6 months. Results: From the beta-blockers class, carvedilol showed a reduction in erythrocyte sedimentation rate (ESR), in low (6.25 mg, bi daily) and medium (12.5 mg, bi daily) doses. At the same time, sacubitril/valsartan showed a reduction in CRP levels. This effect was obtained only in the medium (49/51 mg, bi daily) and high (97/103 mg, bi daily) doses, with the maximum reduction being observed in the high dose. Conclusions: From the classes of medication evaluated, the study showed a significant reduction in ESR levels in the low and medium doses of carvedilol and a reduction in CRP values in the cases of medium and high doses of ARNI.

Reduced congestion and improved response to a fluid/sodium challenge in chronic heart failure patients after initiation of sacubitril/valsartan: The NATRIUM-HF study.

AIMS: The effects of initiating sacubitril/valsartan in patients with stable heart failure with reduced ejection fraction (HFrEF) on response to fluid and sodium expansion are unknown. METHODS AND RESULTS: We have explored changes in natriuresis, diuresis, and congestion in response to the administration of intravenous fluid/sodium load in patients with HFrEF before as compared to after the initiation of sacubitril/valsartan. At baseline (before sacubitril/valsartan initiation) and 2 and 3 months after the initiation, patients underwent an evaluation that consisted of three phases of 3 h: the rest phase (0-3 h), the load phase (3-6 h) in which 1 L of intravenous Ringer solution was administered, and the diuretic phase (6-9 h) at the beginning of which furosemide was administered. Overall, 216 patients completed the study. In comparison to baseline values, at 2 and 3 months after sacubitril/valsartan initiation, patients' diuresis and natriuresis in response to Ringer administration significantly increased (mean difference: 38.8 [17.38] ml, p = 0.0040, and 9.6 [2.02] mmol, p < 0.0001, respectively). Symptoms and signs of congestion after the fluid/sodium challenge were significantly decreased at months 2 and 3 compared to baseline. Compared to baseline, there was also an increment of natriuresis after furosemide administration on sacubitril/valsartan (9.8 [5.13] mmol, p = 0.0167). There was a significant decrease in body weight in subsequent visits when compared to baseline values (-0.50 [-12.7, 7.4] kg at 2 months, and -0.75 [-15.9, 7.5] kg at 3 months; both p < 0.0001). CONCLUSIONS: The initiation of sacubitril/valsartan in HFrEF patients was associated with improvements in natriuresis, diuresis, and weight loss and better clinical adaptation to potentially decongestive stressors.

The Efficacy and Safety of Sacubitril/Valsartan Compared to Valsartan in Patients with Heart Failure and Mildly Reduced and Preserved Ejection Fractions: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Sacubitril/valsartan improves heart failure (HF) outcomes in patients with heart failure with reduced ejection fraction (HFrEF). However, randomized controlled trials (RCTs) in patients with heart failure and mildly reduced ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) have shown inconsistent results. We conducted this meta-analysis to comprehensively evaluate the efficacy and safety of sacubitril/valsartan compared to valsartan within this specific patient population. Methods: We searched the MEDLINE database and ClinicalTrials.gov and identified four RCTs that could be included in our analysis, with 3375 patients in the sacubitril/valsartan group and 3362 in the valsartan group. Results: Our study shows that, in patients with HFmrEF and HFpEF, sacubitril/valsartan was superior to valsartan in some of the key HF outcomes, such as the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ CSS), with a small but significant mean difference of 1.13 (95% confidence interval or CI of 0.15 to 2.11, p-value 0.024), an improvement in the New York Heart Association (NYHA) class (odds ratio or OR of 1.32, 95% CI 1.11 to 1.58, p-value 0.002), and the composite outcome of hospitalizations for HF and cardiovascular death, with a relative risk (RR) of 0.86 (95% CI 0.75 to 0.99, p-value 0.04). However, there was no additional benefit with sacubitril/valsartan compared to valsartan for the outcomes of cardiovascular death and all-cause mortality. In terms of side effects, sacubitril/valsartan was associated with a higher risk of hypotension when compared to valsartan (OR 1.67, 95% CI 1.27 to 2.19, p-value < 0.0001), but did not show an increased risk of hyperkalemia or worsening renal function. Conclusions: In individuals with HFmrEF or HFpEF, sacubitril/valsartan can result in improvements in the HF outcomes of the KCCQ CSS, the NYHA class, and the composite outcome of hospitalization for HF and cardiovascular death when compared to valsartan. While there was a higher risk of hypotension with sacubitril/valsartan compared to valsartan, there was no corresponding increase in the risk of hyperkalemia or worsening renal function.

Effect of sacubitril/valsartan on the hypertensive heart in continuous light-induced and lactacystin-induced pre-hypertension: Interactions with the renin-angiotensin-aldosterone system.

This study investigated whether sacubitril/valsartan or valsartan are able to prevent left ventricular (LV) fibrotic remodelling and dysfunction in two experimental models of pre-hypertension induced by continuous light (24 hours/day) exposure or by chronic lactacystin treatment, and how this potential protection interferes with the renin-angiotensin-aldosterone system (RAAS). Nine groups of three-month-old male Wistar rats were treated for six weeks as follows: untreated controls (C), sacubitril/valsartan (ARNI), valsartan (Val), continuous light (24), continuous light plus sacubitril/valsartan (24+ARNI) or valsartan (24+Val), lactacystin (Lact), lactacystin plus sacubitil/valsartan (Lact+ARNI) or plus valsartan (Lact+Val). Both the 24 and Lact groups developed a mild but significant systolic blood pressure (SBP) increase, LV hypertrophy and fibrosis, as well as LV systolic and diastolic dysfunction. Yet, no changes in serum renin-angiotensin were observed either in the 24 or Lact groups, though aldosterone was increased in the Lact group compared to the controls. In both models, sacubitril/valsartan and valsartan reduced elevated SBP, LV hypertrophy and fibrosis and attenuated LV systolic and diastolic dysfunction. Sacubitril/valsartan and valsartan increased the serum levels of angiotensin (Ang) II, Ang III, Ang IV, Ang 1-5, Ang 1-7 in the 24 and Lact groups and reduced aldosterone in the Lact group. We conclude that both continuous light exposure and lactacystin treatment induced normal-to-low serum renin-angiotensin models of pre-hypertension, whereas aldosterone was increased in lactacystin-induced pre-hypertension. The protection by ARNI or valsartan in the hypertensive heart in either model was related to the Ang II blockade and the protective Ang 1-7, while in lactacystin-induced pre-hypertension this protection seems to be additionally related to the reduced aldosterone level.

Association Between Use of Sodium-Glucose Cotransporter-2 Inhibitors or Angiotensin Receptor-Neprilysin Inhibitor and the Risk of Atherosclerotic Cardiovascular Disease With Coexisting Diabetes and Heart Failure.

PURPOSE: This study was to investigate the association between the use of Sodium-glucose Cotransporter-2 inhibitors (SGLT2i) or angiotensin receptor-neprilysin inhibitor (ARNI; ie, Sacubitril + valsartan, Product name ENTRESTO) and the risk of atherosclerotic cardiovascular disease (ASCVD) in patients with coexisting diabetes and heart failure. Specifically, the study compared outcomes between patients using SGLT2i or valsartan + sacubitril and those not using these medications. METHODS: This study utilized data from the National Health Insurance Research Database (NHIRD) from 2017 to 2018. The case group consisted of 8691 patients with coexisting diabetes and heart failure who did not use SGLT2i or Entresto, while the control group consisted of 8691 patients with coexisting diabetes and heart failure who used SGLT2i or Entresto. The primary outcome was ASCVD, including a composite of cardiovascular death and hospitalization for worsening heart failure. Secondary outcomes included all-cause death, cause of cardiovascular death, and recurrence of heart failure, non-fatal myocardial infarction, non-fatal stroke (including ischemic stroke and hemorrhagic stroke) and new renal replacement therapy. RESULTS: The study found that the use of SGLT2 inhibitors or ARNI was associated with a lower risk of ASCVD in patients with coexisting diabetes and heart failure. CONCLUSION: The study suggests that the use of SGLT2 inhibitors, alone or in combination with Entresto, may be effective in reducing the risk of ASCVD and its associated adverse outcomes in patients with diabetes and heart failure. This finding has important implications for the management of these conditions.

Anti-hypertensive effect of a novel angiotensin II receptor neprilysin inhibitor (ARNi) -S086 in DSS rat model.

Introduction: Angiotensin receptor-neprilysin inhibitor (ARNi), comprised of an angiotensin receptor blocker (ARB) and a neprilysin inhibitor (NEPi), has established itself as a safe and effective intervention for hypertension. S086 is a novel ARNi cocrystal developed by Salubris for the treatment of heart failure and hypertension. Methods: Dahl Salt Sensitive (DSS) hypertensive rat model and telemetry system were employed in this study to investigate the anti-hypertensive efficacy of S086 and compare it with the first ARNi-LCZ696. Results and discussion: The study showed that oral administration of S086 dose-dependently lowered blood pressure (P < 0.001). The middle dosage of S086 (23 mg/kg) exhibited efficacy comparable to LCZ696 (68 mg/kg), while also demonstrating superiority at specific time points (P < 0.05). Notably, water consumption slightly decreased post-treatment compared to the vehicle group. Furthermore, there were significant increases in natriuresis and diuresis observed on the first day of treatment with 23 mg/kg and 68 mg/kg S086 (P < 0.001). However, over the course of treatment, the effects in all treatment groups gradually diminished. This study demonstrates the anti-hypertensive efficacy of S086 in DSS hypertensive rat model, offering promising avenues for the clinical development of S086 as a hypertension treatment.

Assessing the early prognosis of heart failure after acute myocardial infarction using left ventricular pressure-strain loop: a prospective randomized controlled clinical study.

Background: The left ventricular pressure-strain loop (LV-PSL) technique, which is noninvasive and independent of pressure load, is more sensitive than is left ventricular speckle tracking imaging in detecting subtle changes in myocardial function. This study evaluated the improvement in cardiac function after application of LV-PSL in patients with heart failure with reduced ejection fraction (HFrEF) after acute myocardial infarction (MI) treated with sacubitril/valsartan plus dapagliflozin as compared to treatment with sacubitril/valsartan monotherapy. Methods: This prospective, multicenter, open-label study recruited 60 MI survivors with HFrEF between March 2021 and June 2022. The patients were randomly assigned in 1:1 groups, as stratified by center. Patients were randomly categorized into either an observation group [n=30; conventional treatment + 100 mg (49/51 mg) of sacubitril/valsartan, + 10 mg of dapagliflozin] or a control group [n=30; conventional treatment + 100 mg (49/51 mg) of sacubitril/valsartan]. Patients were assessed at three time points: 1 month after discharge (T1), 3 months after discharge (T3), and 6 months after discharge (T6). Two-dimensional ultrasound images were routinely collected, two-dimensional speckle tracking imaging was applied to calculate the left ventricular global longitudinal strain (LV-GLS) rate for both groups, and LV-PSL analysis was used for the assessment of myocardial work, including global work index (GWI), global constructive work (GCW), global wasted work, and global work efficiency. The results at the three follow-up visits were compared with the predischarge results (baseline, T0). Results: Compared with the values at T0, the LV-GLS and left ventricular myocardial work index (LVMWI) values increased in both the observation and control groups at T1, T3, and T6, with GWI and GCW showing significantly greater improvement in the observation group at T6 (GWI: 1,204±336 vs. 987±417 mmHg%, P=0.03; GCW: 1,401±348 vs. 1,206±356 mmHg%, P=0.04). Survival analysis revealed that the overall incidence of major adverse cardiovascular events (MACEs) in the observation group was significantly lower than that in the control group (P=0.03). In a multivariate logistic regression analysis including GCW, GWI, GLS, and left ventricular eject fraction (LVEF), GCW emerged as the only independent predictor of occurrence of MACEs (odds ratio =1.08; 95% CI: 0.63-0.93; P<0.001). Conclusions: Sacubitril/valsartan and dapagliflozin combination therapy led to a moderate improvement of cardiac function in patients with post-MI heart failure (P-MI-HF) compared to treatment with sacubitril/valsartan alone. Moreover, LV-PSL analysis can be used to assess the early prognosis of patients with P-MI-HF.

Updates on New Therapies for Patients with CKD.

Individuals diagnosed with chronic kidney disease (CKD) continue to increase globally. This group of patients experience a disproportionately higher risk of cardiovascular (CV) events compared to the general population. Despite multiple guidelines-based medical management, patients with CKD continue to experience residual cardiorenal risk. Several potential mechanisms explain this excessive CV risk observed in individuals with CKD. Several new drugs have become available that could potentially transform CKD care, given their efficacy in this patient population. Nevertheless, use of these drugs presents certain benefits and challenges that are often underrecognized by prescribing these drugs. In this review, we aim to provide a brief discussion about CKD pathophysiology, limiting our discussion to recent published studies. We also explore benefits and limitations of newer drugs, including angiotensin receptor/neprilysin inhibitors (ARNI), sodium glucose transporter 2 inhibitors (SGLT2i), glucagon-like peptides-1 (GLP-1) agonists and finerenone in patients with CKD. Despite several articles covering this topic, our review provides an algorithm where subgroups of patients with CKD might benefit the most from such drugs based on the selection criteria of the landmark trials. Patients with CKD who have nephrotic range proteinuria beyond 5000 mg/g, or those with poorly controlled blood pressure (systolic ≥160 mm Hg or diastolic ≥100 mm Hg) remain understudied.
