RESUMEN
Simultaneous initiation of quadruple therapy with angiotensin receptor-neprilysin inhibitor, beta-adrenergic receptor blocker, mineralocorticoid receptor antagonist, and sodium glucose cotransporter 2 inhibitor aims at prompt improvement and prevention of readmission in patients hospitalized for heart failure with reduced ejection fraction. However, titration of quadruple therapy is time consuming. Lengthy up-titration of quadruple therapy may negate the benefit of early initiation. Quadruple therapy should start with a sodium glucose cotransporter 2 inhibition and a mineralocorticoid antagonist, as both enable safe decongestion and require minimal or no titration. Depending on the level of decongestion and clinical characteristics, patients receive an angiotensin receptor-neprilysin inhibitor or a beta-adrenergic receptor blocker to be titrated after hospital discharge. Outpatient addition of an angiotensin receptor-neprilysin inhibitor to a beta-adrenergic receptor blocker or vice versa completes the quadruple therapy scheme. By focusing on decongestion and matching intervention to patients' profile, the present therapeutic sequence allows rapid implementation of quadruple therapy at fully recommended doses.

BACKGROUND: The effect of sacubitril/valsartan on patients with heart failure (HF) with preserved ejection fraction (HFpEF) is a topic of ongoing debate. METHODS: Medline was queried from inception through the last week of May 2023 for randomized studies assessing the effects of sacubitril/valsartan in patients with HFpEF. For continuous outcomes, we pooled either the geometric mean ratios (gMR) or weighted mean difference (WMD) with 95% confidence intervals (CI). For dichotomous outcomes, we pooled Risk ratios (RR) with 95% CI. RESULTS: Four trials were included (N=8,129). Compared to the control, sacubitril/valsartan was associated with a reduction in NT-proBNP levels (gMR: 0.84, 95% CI 0.80, 0.88) and improvement in KCCQ score (WMD: 0.85, 95% CI: 0.02, 1.67). We observed no differences for HF hospitalization (RR: 0.90, 95% CI: 0.79, 1.01), cardiovascular mortality (RR: 0.83, 95% CI: 0.52, 1.32), all-cause mortality (RR: 0.99, 95% CI: 0.86-1.13) and improvement (RR: 1.15, 95% CI: 0.93, 1.42) or worsening (RR: 0.92, 95% CI: 0.78, 1.09) of NYHA class between the sacubitril/valsartan and comparator group. Sacubitril/valsartan was generally safe, and patients were less likely to have a ≥50% decline in eGFR compared to control (RR: 0.60, 95% CI: 0.39, 0.92). CONCLUSION: Pooled analysis suggests that sacubitril/valsartan reduces natriuretic peptide levels and improves the quality of life in patients with HFpEF, which may translate into better clinical outcomes as observed by a numerical trend towards improvement in major HF outcomes with sacubitril/valsartan therapy.

BACKGROUND: Portal hypertension develops along with the progression of liver cirrhosis. Natriuretic peptides have been shown to reduce portal pressure but concomitantly activate the renin-angiotensin-aldosterone system (RAAS). Angiotensin receptor-neprilysin inhibitors (ARNIs) upregulate natriuretic peptides and avoid the adverse effects of RAAS activation. ARNIs have been shown to reduce portal pressure in rats with pre-hepatic portal hypertension, which involves relatively little liver injury. This study aimed to evaluate the relevant effects of an ARNI in rats with both liver cirrhosis and portal hypertension. METHODS: Male Sprague-Dawley rats received common bile duct ligation to induce liver cirrhosis and portal hypertension. Sham-operated rats served as surgical controls. All rats were randomly allocated into three groups to receive distilled water (vehicle), LCZ696 (an ARNI), or valsartan for 4 weeks. Portal hypertension and relevant derangements were assessed after treatment. RESULTS: Portal hypertension and hyperdynamic circulation developed in the cirrhotic rats. In the rats with cirrhosis and portal hypertension, both LCZ696 and valsartan reduced portal hypertension, mean arterial pressure, and systemic vascular resistance. The decrease in portal pressure was highly associated with the reduction in arterial pressure and systemic vascular resistance. Blood flow in hepatic, splanchnic, and portosystemic collateral systems was not altered. LCZ696 did not significantly influence liver injury or plasma cytokine levels. Liver fibrosis and splanchnic angiogenesis were not affected. CONCLUSION: ARNI treatment exerted portal pressure lowering effects via peripheral vasodilatation and decreasing systemic arterial pressure in the rats with liver cirrhosis and portal hypertension. Caution should be taken when using ARNIs in liver cirrhosis.

BACKGROUND: Though the combination of an angiotensin receptor blocker (ARB) and a neprilysin inhibitor (ARNi) has been shown to be useful in heart failure with reduced ejection fraction (HFrEF), its use has mostly been restricted to chronic kidney disease (CKD) patients with an estimated glomerular filtration rate (eGFR) >30 mL/minute/1.73 m2 . We studied the role of ARNi in advanced CKD. MATERIALS AND METHODS: Patients with HFrEF and advanced CKD with an eGFR of <30 mL/ minute/1.73 m2 were given ARNi (sacubitril with valsartan) and prospectively studied for changes in hospitalization rate for HF, clinical symptoms, levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP), eGFR, and potassium. RESULTS: Of 34 patients who received ARNi, five were excluded due to hyperkalemia and three due to a decrease in eGFR >30% occurring within 1 month. The remaining 26 patients included 17 with diabetes mellitus (DM) and 23 with underlying coronary artery disease. A total of eight patients had stage 4 and 18 stage 5 CKDs, amongst which eight required hemodialysis. Following ARNi, there was a significant decrease in the need for hospitalization for breathlessness (2.04 ± 1.03-0.23 ± 0.51; p < 0,05), New York Heart Association (NYHA) and Kansas City Cardiomyopathy Questionnaire (KCCQ) scores (3.77 ± 0.43-2.19 ± 0.56 and 28.58 ± 9.04-64.81 ± 14.3, respectively, p < 0.001) and NT-pro-BNP levels (24761 ± 12157.51-20149.92 ± 13555.269, p < 0.05) without significant change in eGFR after 6 months. There were no significant differences in the need for hospitalization, changes in NT proBNP levels and eGFR between stages 4 and 5. CONCLUSION: Neprilysin inhibitor (ARNi) is effective and can be used with care even in patients with CKD stages 4 and 5 having HFrEF with monitoring of eGFR and potassium.

Angiotensin receptor-neprilysin inhibitors (ARNIs) have been approved as antihypertensive agents in Japan, and thiazide diuretics (TZDs) are widely used concomitantly with renin-angiotensin system inhibitors (RASIs) for hypertension. This retrospective study included patients with hypertension who switched from RASI to ARNI therapy (ARNI group) and those who were prescribed TZDs with RASIs (TZD/RASI group). Drug-related changes in the estimated glomerular filtration rate (eGFR), blood pressure (BP), body weight (BW), serum electrolytes, uric acid (UA), and triglyceride levels were compared between the two groups. Overall, 70 participants (31 and 39 in the ARNI and TZD/RASI groups, respectively) were enrolled and observed for a median of 2 months. According to linear mixed models, compared with the TZD/RASI group, the ARNI group exhibited a significant change in mean eGFR of 3.71 mL/min/1.73 m2 [95% confidence interval (CI), 0.57-6.84; P = 0.02] from the time of switching drug to the next outpatient visit. Further, compared with the TZD/RASI group, the ARNI group exhibited significant changes in mean serum UA (-1.27; 95% CI, -1.66 to -0.88), sodium (1.22; 95% CI, 0.12 to -2.32), chloride (2.14; 95% CI, 0.75-3.52), and triglyceride (-52.1; 95% CI, -100.9 to -3.29) levels. Conversely, serum potassium levels, BW, and systolic and diastolic BP did not differ significantly between the two groups (P = 0.69, 0.44, 0.49, and 0.66, respectively). Compared with the combination therapy of TZD and RASI, ARNI therapy causes less renal dysfunction, hyperuricemia, and hypertriglyceridemia with fewer electrolyte abnormalities and no significant difference in antihypertensive effects.

BACKGROUND: Frail older adults may be less likely to receive guideline-directed medical therapy (GDMT)-renin-angiotensin blockers, beta-blockers, and mineralocorticoid receptor antagonists-for heart failure with reduced ejection fraction (HFrEF). We aimed to examine the uptake of angiotensin receptor neprilysin inhibitor (ARNI) and GDMT in frail older adults with HFrEF. METHODS: Using 2015-2019 Medicare data, we estimated the proportion of beneficiaries with HFrEF receiving ARNI and GDMT each year by frailty status, defined by a claims-based frailty index. Logistic regression was used to identify clinical characteristics associated with ARNI initiation. Cox proportional hazards regression was used to examine the association of GDMT use in 2015 and death or heart failure hospitalization in 2016-2019. RESULTS: Among 147,506-180,386 beneficiaries with HFrEF (mean age: 77 years; 27% women; 42.6-49.1% frail) in 2015-2019, the proportion of patients receiving ARNI increased in both non-frail (0.4%-16.4%) and frail (0.3%-13.7%) patients (p for yearly-trend-by-frailty = 0.970). Among those not receiving a renin-angiotensin system blocker, patients with age ≥ 85 years (odds ratio [95% CI], 0.89 [0.80-0.99]), dementia (0.88 [0.81-0.96]), and frailty (0.87 [0.81-0.94]) were less likely to initiate ARNI. The proportion of patients receiving all 3 GDMT classes increased in non-frail patients (22.0%-27.0%) but changed minimally in frail patients (19.6%-21.8%). Regardless of frailty status, treatment with at least 1 class of GDMT was associated with lower death or heart failure hospitalization than no GDMT medications (hazard ratio [95% CI], 0.94 [0.91-0.97], 0.92 [0.89-0.94], 0.94 [0.91-0.97] for 1, 2, and 3 classes, respectively). CONCLUSIONS: Our results suggest an evidence-practice gap in the use of ARNI and GDMT in Medicare beneficiaries with HFrEF, particularly those with frailty. Efforts to narrow this gap are needed to reduce the burden of HFrEF in older adults.

;Heart failure (HF) is a huge global public health task due to morbidity, mortality, disturbed quality of life, and major economic burden. It is an area of active research and newer treatment strategies are evolving. Recently angiotensin receptor-neprilysin inhibitor (ARNI), a class of drugs (the first agent in this class, Sacubitril-Valsartan), reduces cardiovascular mortality and morbidity in chronic HF patients with reduced left ventricular ejection fraction (LVEF). Positive therapeutic effects have led to a decrease in cardiovascular mortality and HF hospitalizations (HFH), with a favorable safety profile, and have been documented in several clinical studies with an unquestionable survival benefit with ARNI, Sacubitril-Valsartan. This consensus statement of the Indian group of experts in cardiology, nephrology, and diabetes provides a comprehensive review of the power and promise of ARNI in HF management and an evidence-based appraisal of the use of ARNI as an essential treatment strategy for HF patients in clinical practice. Consensus in this review favors an early utility of Sacubitril-Valsartan in patients with HF with reduced EF (HFrEF), regardless of the previous therapy being given. A lower rate of hospitalizations for HF with Sacubitril-Valsartan in HF patients with preserved EF who are phenotypically heterogeneous suggests possible benefits of ARNI in patients having 40-50% of LVEF, frequent subtle systolic dysfunction, and higher hospitalization risk.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ß-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

The aim of this study was to determine how sacubitril/valsartan compared with valsartan in an outpatient setting affects left ventricular remodeling in heart failure with reduced ejection fraction and functional (or secondary) mitral regurgitation (SMR) due to the effect of dual inhibition of the renin-angiotensin system and neprilysin. The outpatient study included 90 patients with chronic SMR who were followed up for 12 months. They received sacubitril/valsartan or valsartan instead of the more commonly used angiotensin-converting enzyme inhibitor enalapril for heart failure, in addition to standard medical therapy for heart failure. The difference in NT-proBNP change between groups was the primary endpoint. Changes in effective regurgitation orifice area, left ventricular ejection fraction, left ventricular end-systolic and end-diastolic volume indices, left atrial volume index, E/e' index, and exercise tolerance on the 6-minute walk test were secondary endpoints. In the treatment efficacy analysis, NT-proBNP levels decreased significantly by 37% in the sacubitril/valsartan group and by 11% in the valsartan group (P<0.001). Ejection fraction and exercise tolerance (increase in walking distance in the 6-min test) increased in the sacubitril/valsartan group (P<0.05). Also, in this group, the effective area of the regurgitation orifice, the left atrial volume index, the E/e' index, and the indices of the end-systolic and end-diastolic volume of the left ventricle (P<0.05) decreased more pronouncedly. Compared with valsartan, treatment with sacubitril/valsartan led to a significant improvement in cardiac remodeling in patients with SMR and heart failure with reduced ejection fraction.

BACKGROUND: Angiotensin receptor neprilysin inhibitor (ARNI) and sodium-glucose cotransporter 2 inhibitor (SGLT2i) are emerging medical treatments for decompensated heart failure (HF) with reduced ejection fraction. In clinical practice, the combination of ARNI and SGLT2i cannot be administered owing to the poor hemodynamic status in patients with HF with reduced ejection fraction (HFrEF). This study aimed to compare different strategies of HF management for ARNI first or SGLT2i first in such a population. METHODS: From January 2016 to December 2021, 165 patients were diagnosed with HFrEF and New York Heart Association functional class ≥II and already received optimal medical treatment. Ninety-five patients received the ARNI-first strategy, and 70 patients received the SGLT2i-first strategy according to the physician's choice. Age, sex, hemodynamic condition, etiologies of HF, comorbidities, serum creatinine, N-terminal pro-B-type natriuretic peptide (NT-ProBNP), echocardiographic parameters, and clinical outcomes were compared between the ARNI and SGLT2i-first strategy groups. RESULTS: In the SGLT2i-first group, the median interval between the addition of the second medication was longer (ARNI-first vs. SGLT2i-first; 74 [49-100] days vs. 112 [86-138] days; p = 0.044). Improvement in left ventricular ejection fraction (LVEF), change in left atrial dimension, and change in left ventricular end-diastolic and end-systolic volume (LVESV) did not differ between the two groups. The incidence of HF hospitalization, cardiovascular mortality, and all-cause mortality did not differ between the two groups. A non-significant trend of lower NT-proBNP levels (ARNI-first vs. SGLT2i-first; 1383 [319-2507] pg/mL vs. 570 [206-1314] pg/mL; p = 0.055) and significantly higher discontinuation rate of diuretic agents (ARNI-first vs. SGLT2i- first; 6.8% vs. 17.5%; p = 0.039) were noted in the SGLT2i-first group. When early combination (≤14D) compared to late combination (>14D), better positive remodeling of LVESV presented significantly in early combination subgroups. CONCLUSIONS: In patients with symptomatic HFrEF, SGLT2i-first strategy may provide a higher possibility of discontinuing diuretic agents than the ARNI-first strategy. Changes in LV performance, progression of renal function, and clinical outcomes did not differ between the two groups. Early combination (≤14D) provided better LV remodeling.

BACKGROUND: The aim of this study was to determine the safety and feasibility of in-hospital sacubitril/valsartan initiation after clinical stabilization in patients with acute decompensated heart failure (ADHF) and reduced ejection fraction (EF). METHODS: This retrospective, multicenter observational study included patients admitted for ADHF in 2 Italian centers between February 2017 and January 2022. Feasibility was evaluated by assessing the proportion of patients discharged on sacubitril/valsartan. Key safety endpoints were the incidences of adverse events during hospitalization and during follow-up planned at 1 month, 3-6 months and 12-18 months after discharge. RESULTS: One hundred and twenty-two patients were included. Median age was 71 (60-78) years, 78% male, 63% New York Heart Association (NYHA) Class III at admission with a median left ventricular ejection fraction (EF) of 25% (20-30). During hospitalization, 94 (77%) patients were treated with intravenous diuretics, 39 (32%) with inotrope/vasopressor, 51 (42%) with continuous positive airway pressure ventilation and 7 (6%) were assisted with an intra-aortic balloon pump. Median time from hospitalization to sacubitril/valsartan initiation was 4 (2-7) days. Sacubitril/valsartan was started at a dosage of 12/13 mg in 52 (43%) patients, 24/26 mg in 61 (50%) patients and 49/51 mg in 8 (7%) patients. Overall, 111 (91%) patients were discharged on sacubitril/valsartan. At 12-18-month follow-up, the vast majority of patients were still on sacubitril/valsartan therapy. CONCLUSIONS: In-hospital initiation of sacubitril/valsartan treatment in real-world ADHF patients may be a safe and feasible treatment option.

Intercellular adhesion molecule 1 (ICAM1) is a vessel adhesion protein induced during brain vascular inflammation, which could be closely linked with the development of Alzheimer's disease (AD). This study investigated the effect of ICAM1 on amyloid-degrading enzymes (ADEs) in endothelial cells and their potential involvement in inflammation and AD progression. TNF-α treatment increased ICAM1 in human brain microvascular endothelial cells (HBMVECs) but decreased the neprilysin (NEP) protein level. Knock-down of ICAM1 using siRNA enhanced NEP, which increased the degradation of amyloid-ß. In the brains of 4-month-old AD transgenic mice (APPswe/PSEN1dE9), there were significantly higher levels of ICAM1 expression and amyloid deposits but lower levels of NEP and insulin-degrading enzymes (IDE), demonstrating an inverse correlation of ICAM1 with NEP and IDE expression. Further studies demonstrated significantly increased GFAP protein levels in the brain, specifically localized near blood vessels, of both TNF-α-injected and 4-month-old AD transgenic mice. Taken together, the induction of ICAM1 in endothelial cells suppresses NEP expression, accelerating the accumulation of amyloid-ß in blood vessels. It also enhances leukocyte adhesion to blood vessels stimulating the migration of leukocytes into the brain, subsequently triggering brain inflammation.

Background: Heart failure guidelines recommend replacing an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) with an angiotensin receptor neprilysin inhibitor (ARNI) to reduce morbidity and mortality in NYHA Class II-III patients with reduced ejection fraction (HFrEF). Objective: This study aims to determine if a pharmacist-led outpatient ARNI replacement and titration program led to more patients achieving target doses of ARNI compared to usual care. Methods: A single health system, retrospective electronic medical record review identified 791 patients with active ARNI prescriptions and at least two outpatient cardiology visits with a pharmacist or usual care provider between January 2015 through September 2018. The primary outcome was the percentage of patients who achieved a target ARNI dose of 97/103 mg twice daily. The secondary outcomes were the median dose achieved, number of visits required to achieve target dose, hospitalizations, and all-cause death. Results: ARNI was initiated and continued by a pharmacist in 64 patients and 727 by usual care. More patients in the pharmacist group, 60.9% (n = 39), achieved target dose vs. 18.0% (n = 131) of patients managed by usual care (95% CI, 0.31-0.55, p < 0.0001). The pharmacist group also had higher median total daily dose of ARNI (200 mg (IQR = 300) vs 100 mg (IQR = 100), p < 0.0001) and more likely to achieve a higher total daily dose in fewer visits. Conclusions: An advanced practice provider pharmacist-led outpatient ARNI replacement and titration program was more effective in achieving target doses of ARNI in HFrEF patients as compared to usual care.

The management of heart failure with preserved ejection fraction (HFpEF) is rapidly evolving. The pharmacologic treatment of patients with HFpEF includes symptom management with diuretics and optimization of comorbidities, including hypertension, obesity, diabetes mellitus, and atrial fibrillation. Specific therapies, including angiotensin II receptor blockers, mineralocorticoid receptor antagonists, angiotensin receptor-neprilysin inhibitors, and sodium-glucose cotransporter-2 inhibitors, are well tolerated and can reduce the risk of HF hospitalization, particularly in those on the lower end of the HFpEF left ventricular ejection fraction spectrum. Ongoing trials should continue to inform optimal therapy in this evolving field.

BACKGROUND: Sacubitril/valsartan is a first-in-class angiotensin receptor-neprilysin inhibitor (ARNI) that is now preferred in guidelines over angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) for patients with heart failure with reduced ejection fraction (HFrEF). However, it has not been broadly adopted in clinical practice. OBJECTIVE: To characterize ARNI use within a large diverse real-world population and assess for any racial disparities. METHODS: We conducted a cross-sectional study within Kaiser Permanente Southern California. Adult patients with HFrEF who received ARNIs, ACEIs, or ARBs between January 1, 2014, and November 30, 2020, were identified. The prevalence of ARNI use among the cohort and patient characteristics by ARNIs vs ACEIs/ARBs use were described. Multivariable regression was performed to estimate odds ratios and 95% CIs of receiving ARNI by race and ethnicity. RESULTS: Among 12,250 patients with HFrEF receiving ACEIs, ARBs, or ARNIs, 556 (4.54%) patients received ARNIs. ARNI use among this cohort increased from 0.02% in 2015 to 7.48% in 2020. Patients receiving ARNIs were younger (aged 62 vs 69 years) and had a lower median ejection fraction (27% vs 32%) compared with patients receiving ACEIs/ARBs. They also had higher use of mineralocorticoid antagonists (24.1% vs 19.8%) and automatic implantable cardioverterdefibrillators (17.4% vs 13.3%). There were no significant differences in rate of ARNI use by race and ethnicity. CONCLUSIONS: Within a large diverse integrated health system in Southern California, the rate of ARNI use has risen over time. Patients given ARNIs were younger with fewer comorbidities, while having worse ejection fraction. Racial minorities were no less likely to receive ARNIs compared with White patients. DISCLOSURES: Dr Huang had stock ownership in Gilead and Pfizer. Dr Liang received support for article processing and medical writing.

Importance: In recent years, significant progress has been made in the pharmacologic treatment of heart failure (HF) with reduced ejection fraction (HFrEF), but there is still insufficient evidence for drug therapy for HF with preserved ejection fraction (HFpEF) and mildly reduced ejection fraction (HFmrEF). Objective: To compare the outcomes associated with different drug combinations for the treatment of HFpEF and HFmrEF. Data Sources: A search of the PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted for studies published from inception to October 9, 2021. Study Selection: Randomized clinical trials on the use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitors (ARNIs), mineralocorticoid receptor antagonists (MRAs), ß-blockers, and sodium-glucose cotransporter 2 (SGLT2) inhibitors for patients with HFpEF or HFmrEF. Data Extraction and Synthesis: Data extraction and bias assessment were independently performed by 2 reviewers following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. All data for 3 outcomes were pooled with a fixed-effect model. Main Outcomes and Measures: The main outcomes were first hospitalization for HF, all-cause mortality, and cardiovascular mortality. Hazard ratios (HRs) and 95% credible intervals (CrIs) were evaluated using a bayesian network meta-analysis model. Results: In this analysis, 19 randomized clinical trials, including 20â¯633 patients with HF and an ejection fraction of 40% or more, without a remarkable risk of bias were included. Compared with placebo, no treatments were associated with a significant reduction in the risk of all-cause death or cardiovascular death. SGLT2 inhibitors, ARNIs, and MRAs were associated with a significant decrease in the risk of HF hospitalization compared with placebo (SGLT2 inhibitors: HR, 0.71 [95% CrI, 0.60-0.83]; ARNIs: HR, 0.76 [95% CrI, 0.61-0.95]; MRAs: HR, 0.83 [95% CrI, 0.69-0.99]), and SGLT2 inhibitors were the optimal drug class in terms of reducing the risk for HF admission. Sensitivity analysis results demonstrated a progressive decrease in the risk of HF admission and an advance in mean rank associated with the increasing use of drug classes. Conclusions and Relevance: The findings of this study suggest that SGLT2 inhibitors were the optimal drug class for HFpEF and HFmrEF, consistent with the most recent guideline recommendation. The incremental use of combinations of SGLT2 inhibitors, ACE inhibitors or ARBs, and ß-blockers may be associated with accumulative benefits in HF hospitalization rather than all-cause death among patients with HFpEF and HFmrEF.

INTRODUCTION: Heart failure (HF) is a major cause of morbidity and mortality, with nearly half of all HF-related deaths resulting from sudden cardiac death (SCD), most often from an arrhythmic event. The pathophysiologic changes that occur in response to the hemodynamic stress of HF may lead to increased arrhythmogenesis. Theoretically, medications that block these arrhythmogenic substrates would decrease the risk of SCD. The combined angiotensin receptor and neprilysin inhibitor (ARNi; tradename Entresto) is the newest commercially available medication for the treatment of heart failure. METHODS AND RESULTS: We reviewed and synthesized the available literature regarding sacubitril/valsartan and its effects on cardiac rhythm. ARNi has been shown to decrease cardiovascular mortality and hospitalization in patients with HF with reduced ejection fraction (HFrEF). Emerging evidence suggests that ARNi also may play a role in reducing arrhythmogenesis and thereby SCD. CONCLUSION: This review summarizes the current data regarding this ARNi and its potential antiarrhythmic effects.

INTRODUCTION: This consensus statement of Australian clinicians provides new recommendations for the pharmacological management of heart failure based on studies reported since the publication of the 2018 Australian heart failure guidelines. MAIN RECOMMENDATIONS: âªUse of sodium-glucose cotransporter 2 (SGLT2) inhibitors to prevent hospitalisation for heart failure in type 2 diabetes mellitus can be extended to patients with multiple cardiovascular risk factors, albuminuric chronic kidney disease, or atherosclerotic cardiovascular disease. âªNew evidence supports the use of a mineralocorticoid receptor antagonist (finerenone) to prevent heart failure in type 2 diabetes mellitus associated with albuminuric chronic kidney disease. âªIn addition to renin angiotensin system inhibitors (angiotensin receptor neprilysin inhibitor preferred), beta blockers and mineralocorticoid receptor antagonists, an SGLT2 inhibitor (dapagliflozin or empagliflozin) is recommended in all patients with heart failure with reduced left ventricular ejection fraction (LVEF ≤ 40%) (HFrEF). Lower quality evidence supports these therapies in patients with heart failure with mildly reduced LVEF (41-49%) (HFmrEF). âªA soluble guanylate cyclase stimulator (vericiguat), selective cardiac myosin activator (omecamtiv mecarbil) and, if iron deficient, intravenous iron (ferric carboxymaltose) provide additional benefits in persistent HFrEF. âªAn SGLT2 inhibitor (empagliflozin) should be considered in patients with heart failure with preserved LVEF (≥ 50%) (HFpEF). Key changes in management from this statement: This document broadens the scope of angiotensin receptor neprilysin inhibitor use in patients with HFrEF and HFmrEF. SGLT2 inhibitor use expands to become a cornerstone therapy in HFrEF, with increasing evidence to support its use in HFmrEF and HFpEF.

Cardiac remodelling is an adverse phenomenon linked to heart failure progression and an important contributor to heart failure severity. Cardiac remodelling could represent the real therapeutic goal in the treatment of patients with heart failure with reduced ejection fraction, being potentially reversed through different pharmacotherapies. Currently, there are well-established drugs such as angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers and ß-blockers with anti-remodelling effects; recently, angiotensin receptor neprilysin inhibitor effects on inhibiting cardiac remodelling (improving N-terminal pro-B-type natriuretic peptide levels, echocardiographic parameters of reverse cardiac remodelling and right ventricular function in patients with heart failure with reduced ejection fraction) were demonstrated. More recently, hemodynamic consequences of gliflozins, reduced cardiac hydrostatic pressure as a possible cause of ventricular remodelling and hypertrophy were proposed to explain potential anti-remodelling effects of gliflozins. Gliflozins exert their cardioprotective effects by attenuating myofibroblast activity and collagen-mediated remodelling. Another postulated mechanism is represented by the reduction in sympathetic activity, through the reduction in renal afferent nervous activity and the suppression of central reflex mechanisms. Benefits of gliflozins on left ventricular hypertrophy, dilation, and systolic and diastolic function were also described. In this review, we aimed to provide a wide overview on cardiac remodelling with a particular focus on possible anti-remodelling effects of angiotensin receptor neprilysin inhibitors and gliflozins.
