The Impact of Sacubitril/Valsartan on Heart Failure Patient with Reduced Left Ventricular Ejection Fraction: Single Center Retrospective Study in Saudi Arabia.

Background: Sacubitril/valsartan (S/V) is used in managing heart failure with reduced ejection fraction (HFrEF), reducing morbidity and mortality while improving symptoms and prognosis. This study aims to evaluate the effectiveness of S/V in patients with reduced left ventricular ejection fraction (LVEF) and its safety. Methods:  This retrospective cohort study included adult patients aged ≥18 years diagnosed with HFrEF, receiving S/V, and followed up at a tertiary hospital in Riyadh. Primary outcomes included improvements in LVEF on echocardiography and the number of hospitalizations due to acute decompensated heart failure (ADHF). Secondary outcomes assessed the safety profile of S/V. Multinomial logistic regression analysis was performed with statistical significance set at P < 0.05. . Results: The study included 107 patients: 80 with LVEF < 30% and 27 with LVEF 30-40%. Six-month follow-up, LVEF improvement was categorized into three groups: no improvement, LVEF increased by 1 to <10 points, and LVEF increased by ≥10 points. The LVEF was similar across groups (P = 0.59). Although hospitalizations due to ADHF were not significantly different between groups, they numerically decreased after initiating S/V (P = 0.1). S/V was generally well tolerated. Conclusion: This study suggests no significant benefit from S/V regarding LVEF improvement. It is recommended that heart failure clinics assess and titrate S/V to the maximum tolerated dose.

A clinical randomized trial: Effects of early application of sacubitril/valsartan on ventricular remodeling and prognosis in acute myocardial infarction patients.

Objectives: To explore the effects of early application of sacubitril/valsartan on ventricular remodeling and prognosis in patients with acute myocardial infarction (AMI). Methods: Total of 295 patients with AMI admitted to the hospital were enrolled between August 2019 and August 2021. According to different treatment methods, they were divided into observation group (sacubitril/valsartan sodium tables combined with standard treatment, 132 patients) and control group (benazepril hydrochloride tablets combined with standard treatment, 163 patients). The levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP), creatinine (Cr) and serum K+ before and at 6 months after treatment, standard deviation of all normal-to-normal intervals (SDNN), standard deviation of the average all normal-to-normal intervals (SDANN), root mean square of differences between adjacent normal-to-normal intervals/root mean square differences of successive R-R (RMSSD), left ventricular end-diastolic volume (LVEDV), left ventricular ejection fraction (LVEF) and left ventricular end-systolic volume (LVESV) in the two groups were compared. The adverse reactions during treatment and major adverse cardiac events (MACE) during 6 months of follow-up in both groups were statistically analyzed. Results: The levels of NT-proBNP, Cr and K+, LVEDV and LVESV in observation group were significantly lower than those in control group (P < 0.05), while LVEF, SDNN, SDANN and RMSSD were significantly higher than those in control group (P < 0.05). The incidence of MACE in observation group was lower than that in control group during 6 months of follow-up (7.58 % vs 27.61 %, P < 0.05), but there was no significant difference in the incidence of adverse reactions (9.85 % vs 12.88 %, P > 0.05). Conclusion: Early application of sacubitril/valsartan sodium can effectively delay ventricular remodeling, improve cardiac function and heart rate variability indexes, reduce NT-proBNP level and improve prognosis in AMI patients.

Race in Heart Failure: A Pooled Participant-Level Analysis of the Global PARADIGM-HF and PARAGON-HF Trials.

BACKGROUND: Mechanisms of disease pathobiology, prognosis, and potentially treatment responses might vary by race in patients with heart failure (HF). OBJECTIVES: The authors aimed to examine the safety and efficacy of sacubitril/valsartan among patients with HF by self-reported race. METHODS: PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) and PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF With Preserved Ejection Fraction) were global, randomized clinical trials testing sacubitril/valsartan against a renin-angiotensin system inhibitor ([RASi], enalapril or valsartan, respectively) in patients with HF and left ventricular ejection fraction ≤40% (PARADIGM-HF) or left ventricular ejection fraction ≥45% (PARAGON-HF). Patients with self-reported race were categorized as White, Asian, or Black. We assessed the composite of first HF hospitalization or cardiovascular death, its components, and angioedema across races. RESULTS: Among 12,097 participants, 9,451 (78.1%) were White, 2,116 (17.5%) were Asian, and 530 (4.4%) were Black. Over a median follow-up of 2.5 years, Black (adjusted HR: 1.68; 95% CI: 1.42-1.98) and Asian patients (adjusted HR: 1.32; 95% CI: 1.18-1.47) experienced higher risks of the primary outcome compared with White patients. Treatment effects of sacubitril/valsartan vs RASi on the primary endpoint were consistent among White (HR: 0.84; 95% CI: 0.77-0.91), Asian (HR: 0.92; 95% CI: 0.78-1.10), and Black patients (HR: 0.79; 95% CI: 0.58-1.07; Pinteraction = 0.58). Rates of severe angioedema were higher with sacubitril/valsartan vs RASi (White: 0.2% vs 0.1%; Black: 1.5% vs 0.0%; Asian: 0.1% vs 0.1%). CONCLUSIONS: In a pooled experience of 2 global trials, Black and Asian patients exhibited a higher risk of cardiovascular events than White patients. The benefits of sacubitril/valsartan were consistent across races. Risks of severe angioedema were low but numerically higher with sacubitril/valsartan.

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.

Efficacy of sacubitril-valsartan vs. angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in preventing atrial fibrillation recurrence after catheter ablation: a systematic review and meta-analysis.

BACKGROUND: Patients who have undergone catheter ablation for atrial fibrillation (AF) may experience recurrence of this condition. The efficacy of sacubitril-valsartan (S/V) in preventing AF recurrence compared with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) is not established. This meta-analysis aimed to establish the best therapeutic choice for preventing AF recurrence after catheter ablation. METHOD: A systematic search of the PubMed, Embase, and Cochrane databases was conducted for randomized controlled trials (RCTs) and observational studies comparing the use of S/V with ACEI/ARB in patients who underwent catheter ablation. Results are presented as mean difference (MD) with 95% confidence interval (CI). Heterogeneity was assessed with the I2 statistic, and outcomes are expressed as relative risk (RR). R software version 4.2.3 was used for the analysis. RESULTS: Three RCTs and one cohort study, comprising 642 patients with 319 patients in the S/V group and 323 in the control group, were included. Follow-up ranged from 6 to 36 months, with mean ages ranging from 58.9 to 65.8 years. A significant reduction in persistent AF occurrence was demonstrated favoring the S/V group (RR: 0.54; 95% CI: [0.41, 0.70]; p = 0.000004; I2: 80%) over the ACEI/ARB group. There was no significant difference in left ventricular ejection fraction with S/V use (MD: 1.23; 95% CI: [-0.12, 2.60]; p = 0.076; I2: 0%) compared with ACEI/ARB. The analysis also showed a significant reduction in left atrial volume index (MD: -5.33; 95% CI: [-8.76, -1.90]; p = 0.002; I2: 57%) in the S/V group compared with the ACEI/ARB group. CONCLUSION: This meta-analysis demonstrated the efficacy of S/V in reducing the incidence of AF in patients undergoing catheter ablation compared with the use of ACEI/ARB. However, more RCTs are needed for a comprehensive evaluation of its efficacy in reducing AF recurrence after catheter ablation in clinical practice.

Changes in urinary output due to concomitant administration of sacubitril/valsartan and atrial natriuretic peptide in patients with heart failure: a multicenter retrospective cohort study.

BACKGROUND: Sacubitril/valsartan is an angiotensin receptor neprilysin inhibitor (ARNI) that inhibits the degradation of endogenous natriuretic peptides. Therefore, ARNIs may increase the efficacy of human atrial natriuretic peptide (hANP), a drug for acute heart failure, by mediating its pharmacological mechanism. This study was aimed at evaluating the effects of ARNIs on the pharmacological effects of hANP by using surrogate marker, such as urinary output, in patients with heart failure. METHODS: In this multicenter retrospective cohort study, adult patients with heart failure who were taking angiotensin II receptor blockers (ARB) or ARNIs combined with hANP were enrolled. Information on basic characteristics, clinical laboratory data, medical history, and severity of cardiac insufficiency were collected from electronic medical records. The primary outcome was the change in adjusted fluid balance, calculated by IN-volume (mL/day) - OUT-volume (mL/day) / daily hANP dosage (µg). RESULTS: Ninety-two and 62 patients in the ARB + hANP and ARNI + hANP groups, respectively, were eligible for analysis. The adjusted fluid balance in the ARNI + hANP group was significantly lower than that in the ARB + hANP group (p = 0.001). After propensity score matching, 27 patients from each group were included. Similarly, there was a significant reduction in adjusted fluid balance in the ARNI + hANP group after propensity score matching (p = 0.026). CONCLUSIONS: These findings suggest that ARNIs may enhance the efficacy of hANP and the combination of the two may be effective in the treatment of heart failure.

Sex differences in cardiac structure and function following acute myocardial infarction: Insights from the PARADISE-MI echocardiographic substudy.

AIMS: The incidence of heart failure hospitalization is higher in women than in men after myocardial infarction (MI). Sex-related differences in left ventricular (LV) remodelling may contribute to the differences in post-MI outcomes. The aim of this study was to assess sex differences in echocardiographic parameters post-MI, and whether the relationship between echocardiographic parameters and clinical outcomes differs by sex. METHODS AND RESULTS: In the PARADISE-MI trial, patients were randomized to sacubitril/valsartan or ramipril within 0.5 to 7 days of high-risk MI. In the pre-specified echocardiographic substudy, 544 patients underwent echocardiography at the time of randomization and after 8 months. We compared key echocardiographic parameters in men and women and their association with primary composite outcome (cardiovascular death or incident heart failure). At baseline, women had higher LV ejection fraction (LVEF), lower LV end-diastolic volume (LVEDV) index, LV end-systolic volume (LVESV) index, and LV mass index. After adjusting for baseline clinical differences, changes in these echocardiographic parameters from baseline to 8 months were not significantly different in women versus men. Lower LVEF, higher LVEDV, LVESV, left atrial volume index, and average E/e' were associated with a higher risk of the primary composite outcome. Sex did not modify the relationship between echocardiographic parameters and clinical outcome. CONCLUSIONS: Despite baseline differences in measures of cardiac function between men and women following acute high-risk MI, there were no significant sex-related changes in chamber size or LV function. Sex did not modify the association between echocardiographic parameters and clinical outcome.

Incidence and risk factors of hypotension-related adverse events among Japanese patients with heart failure receiving sacubitril/valsartan or enalapril: Results from the PARALLEL-HF study.

BACKGROUND: The PARALLEL-HF trial showed that treatment with sacubitril/valsartan resulted in more symptomatic hypotension versus enalapril in Japanese patients with heart failure (HF) and reduced ejection fraction, similar to PARADIGM-HF. Use of sacubitril/valsartan in these patients may be limited by concerns regarding hypotension. METHODS: This post-hoc analysis characterized hypotension-related adverse events (AEs) and their effects on efficacy using data from PARALLEL-HF, in which patients received sacubitril/valsartan 200 mg twice daily or enalapril 10 mg twice daily. RESULTS: Of 223 patients, 28.2 % experienced hypotension-related AEs and incidence was higher with sacubitril/valsartan versus enalapril (hazard ratio, 2.2; 95 % CI, 1.3-3.8; p = 0.0027). However, reduction in mean systolic blood pressure from baseline to study end did not significantly differ (sacubitril/valsartan: -2.2 mmHg vs enalapril: -1.3 mmHg; p = 0.6895). Patients who experienced hypotension-related AEs had lower mean body mass index, higher median N-terminal pro-brain natriuretic peptide at randomization, and more frequent history of stroke. Hypotension-related AEs leading to treatment discontinuation were not significantly different for sacubitril/valsartan versus enalapril (3.4 % vs 6.9 %, p = 0.5957). Reduction in risk of cardiovascular death or HF hospitalization was similar with sacubitril/valsartan versus enalapril in patients with or without hypotension-related AEs. CONCLUSIONS: Incidence of hypotension-related AEs was higher in the sacubitril/valsartan versus enalapril group but did not affect risk of cardiovascular death or HF hospitalization, which was similar between treatment groups.

Asymptomatic vs Symptomatic Hypotension With Sacubitril/Valsartan in Heart Failure and Reduced Ejection Fraction in PARADIGM-HF.

BACKGROUND: Hypotension is an important clinical problem in heart failure (HF). OBJECTIVES: This study sought to examine the association between asymptomatic vs symptomatic hypotension and outcomes in PARADIGM-HF (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure). METHODS: In a post hoc analysis of PARADIGM-HF, the efficacy and safety of sacubitril/valsartan compared to enalapril were estimated using time-updated Cox proportional hazards models. The primary outcome was cardiovascular death or HF hospitalization. RESULTS: Among 8,399 patients in PARADIGM-HF, 1,343 (16.0%) experienced only asymptomatic hypotension, and 936 (11.1%) experienced symptomatic hypotension at least once after randomization. Patients with symptomatic hypotension were older and more frequently had cardiovascular comorbidities compared to those developing only asymptomatic hypotension. By contrast, left ventricular ejection fraction was lower in those with asymptomatic hypotension. Patients who experienced either type of hypotension were at higher risk for all outcomes examined. However, the effect of sacubitril/valsartan on the primary outcome was not diminished in patients experiencing hypotension compared to those who did not: the HR for sacubitril/valsartan vs enalapril was 0.80 (95% CI: 0.72-0.89) for no hypotension, 0.87 (95% CI: 0.70-1.08) for asymptomatic hypotension, and 0.51 (95% CI: 0.38-0.69) for symptomatic hypotension (Pinteraction = 0.01), and this was also true for cardiovascular and all-cause deaths. The safety of sacubitril/valsartan vs enalapril was also maintained regardless of the occurrence of hypotension. Discontinuation of randomized treatment was less common with sacubitril/valsartan vs enalapril in patients experiencing asymptomatic and symptomatic hypotension. CONCLUSIONS: Although both asymptomatic and symptomatic hypotension during treatment with sacubitril/valsartan or enalapril were associated with worse outcomes, the benefits of sacubitril/valsartan were maintained (or even enhanced) in patients experiencing hypotension.

Sacubitril/valsartan attenuated myocardial inflammation, fibrosis, apoptosis and promoted autophagy in doxorubicin-induced cardiotoxicity mice via regulating the AMPKα-mTORC1 signaling pathway.

This study aimed to investigate the potential cardioprotective effects of sacubitril/valsartan (Sac/Val) in mice with doxorubicin (DOX)-induced cardiomyopathy, a common manifestation of cancer therapy-related cardiac dysfunction (CTRCD) associated with DOX. A total of thirty-two mice were equally classified into 4 groups: control group, DOX (total 24 mg/kg), Sac/Val (80 mg/kg), and Sac/Val + DOX (Sac/Val was given from seven days before doxorubicin administration). Neonatal rat ventricular myocytes was exposed to 5 µM of DOX for 6 h in vitro to mimic the in vivo conditions. A variety of techniques were used to investigate cardiac inflammation, fibrosis, apoptosis, and autophagy, including western blot, real-time quantitative PCR (RT-qPCR), immunohistochemistry, and fluorescence. Mice with DOX-induced cardiotoxicity displayed impaired systolic and diastolic function, characterized by elevated levels of cardiac inflammation, fibrosis, cardiomyocyte hypertrophy, apoptosis, and autophagy inhibition in the heart. Treatment with Sac/Val partially reversed these effects. In comparison to the control group, the protein expression of NLRP3, caspase-1, collagen I, Bax, cleaved caspase-3, and P62 were significantly increased, while the protein expression of Bcl-2 and LC3-II were significantly decreased in the myocardial tissues of the Dox-induced cardiomyopathy group. The administration of Sac/Val demonstrated the potential to partially reverse alterations in protein expression within the myocardium of mice with DOX-induced cardiotoxicity by modulating the AMPKα-mTORC1 signaling pathway and suppressing oxidative stress. Additionally, Sac/Val treatment may mitigate Dox-induced apoptosis and inhibition of autophagy in primary cardiomyocytes. Sac/Val seems to be cardioprotective against DOX-induced cardiotoxicity in the pre-treatment mice model. These findings could be attributed to the anti-inflammatory, antioxidant, anti-apoptotic, and de-autophagy effects of Sac/Val through regulation of the AMPKα-mTORC1 signaling pathway.

Sacubitril/valsartan alleviates myocardial infarction-induced inflammation in mice by promoting M2 macrophage polarisation via regulation of PI3K/Akt pathway.

BACKGROUND: Macrophage polarisation-mediated inflammation plays a critical role in ventricular remodelling after myocardial infarction (MI). Sacubitril/Valsartan (Sac/Val) is an angiotensin receptor-neprilysin inhibitor that has shown beneficial effects on MI and heart failure. This study aims to further explore the mechanisms by which Sac/Val exerts its protective effects against MI. METHODS: A mouse MI model was induced by ligating the left anterior descending coronary artery, followed by Sac/Val administration. TTC staining and Masson trichrome staining were employed for estimating myocardial infarct size and fibrosis, respectively. The expression levels of proinflammatory factors were determined by ELISA and RT-qPCR. Flow cytometry and immunofluorescence staining were implemented to detect CD206-positive cell infiltration in mouse hearts. Western blotting was conducted to assess protein levels of Arg1, pro-fibrotic factors, and PI3K/Akt signalling-related markers. RESULTS: Sac/Val treatment reduced myocardial infarct size and fibrosis in mice after MI. Sac/Val administration decreased proinflammatory cytokine production and facilitated M2 macrophage polarisation in MI mouse cardiac tissues. Sac/Val activated PI3K/Akt signalling in MI mouse hearts. Blocking PI3K/Akt signalling counteracted Sac/Val-mediated protective effects in MI mice. CONCLUSION: Sac/Val ameliorates MI-induced inflammation by facilitating M2 macrophage polarisation and activating PI3K/Akt signalling.

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.

Left ventricular reverse remodeling after combined ARNI and SGLT2 therapy in heart failure patients with reduced or mildly reduced ejection fraction.

Background: Cardiac remodeling is an adverse phenomenon linked to heart failure (HF) progression. Cardiac remodeling could represent the real therapeutic goal in the treatment of patients with HF and reduced ejection fraction (HFrEF), being potentially reversed through different pharmacotherapies. Currently, there are well-established drugs such as ACEi/ARBs and ß-blockers with anti-remodeling effects. More recently, ARNI effects on cardiac remodeling were also demonstrated; additional potential benefits of gliflozins remain non clearly demonstrated. Aim of study: To evaluate possible changes in cardiac remodeling in patients with HFrEF/HFmrEF in treatment with ARNI or ARNI plus SGLT2i and the potential benefit on cardiac remodeling of adding SGLT2i to ARNI. Methods: Between June 2021 and August 2023, 100 consecutive patients with HFrEF/HFmrEF underwent conventional and advanced echocardiography (TDI, 2DSTE): patients were therefore divided into three groups according to therapy with neither ARNI nor SGLT2i, just ARNI or both. After 3 months, all patients underwent echocardiographic follow-up. Results: After a 3 months of therapy, significant improvements were observed for LVEF, LVEDD, LVEDV, LVESV, LV mass, E/e', LV GLS, TAPSE (ANOVA p< 0.01 in all cases), RV S' velocity (ANOVA p< 0.001).The trend in favor of additional treatment with SGTL2i over ARNI remained statistically significant even after multivariable analysis (p< 0.001 for LVEF, LVEDD; p< 0.01 for LV GLS, TAPSE, TRVS; p< 0.05 for LV mass). Conclusions: SGLT2i therapy when added to the standard treatment for HFrEF and HFmrEF is associated with an improved biventricular function and ventricular dimensions at follow-up.

Efficacy and safety of angiotensin receptor-neprilysin inhibition in heart failure patients with end-stage kidney disease on maintenance dialysis: A systematic review and meta-analysis.

AIMS: Angiotensin receptor-neprilysin inhibitor (ARNI) has played an increasingly important role in the management of heart failure (HF). However, the evidence on the benefits of ARNI in HF patients with end-stage kidney disease (ESKD) undergoing dialysis is limited. This study aimed to investigate the efficacy and safety of ARNI in patients with concomitant HF and ESKD on maintenance dialysis. METHODS AND RESULTS: We systematically searched the MEDLINE, Embase, Web of Science, Cochrane, and ClinicalTrials.gov databases for studies reporting outcomes after ARNI treatment in HF patients with ESKD on dialysis. All meta-analyses were performed using the random effects model. Twenty-six studies comprising 2494 patients with concomitant HF and ESKD undergoing dialysis were included. Our synthesis showed a significant improvement in left ventricular ejection fraction (LVEF) between before and after ARNI treatment (mean change: 8.05%; 95% confidence interval [CI] 5.57-10.54). Compared to the conventional group, the ARNI group showed a greater improvement in LVEF (mean difference: 4.03%; 95% CI 2.90-5.16). This effect was more pronounced in patients with HF with reduced ejection fraction (pinteraction < 0.0001). Patients treated with ARNI had a lower risk of all-cause mortality (risk ratio [RR] 0.64; 95% CI 0.45-0.92; p = 0.01) but had a similar rate of HF hospitalization (RR 0.71; 95% CI 0.43-1.18; p = 0.19). ARNI treatment showed benefits in the improvement of left ventricular end-systolic diameter, left ventricular mass index, left atrial diameter, and E/e' ratio (p < 0.05), while it did not significantly increase the risk of severe hyperkalaemia (p = 0.33) or symptomatic hypotension (p = 0.53). CONCLUSION: This meta-analysis provided insights into the benefits of ARNI in HF patients with ESKD undergoing dialysis by improving left ventricular function, reversing left ventricular remodelling, and reducing the risk of all-cause mortality, without increasing the risk of HF hospitalizations, severe hyperkalaemia, and symptomatic hypotension.

Efficacy of Sacubitril Valsartan sodium tablets in patients with heart failure combined with pulmonary infection and long-term recurrence rate.

OBJECTIVE: To observe the therapeutic effect of Sacubitril Valsartan sodium tablets (SVST) on heart failure (HF) complicated by pulmonary infection (PI), and to provide a reference for future medication. METHODS: A total of 89 patients with HF complicated by PI who were treated at Dongying People's Hospital from January 2019 to May 2020 were selected as study subjects in this retrospective study. The control group consisted of 41 patients who received conventional treatment, while the study group included 48 patients who received SVST in addition to conventional treatment. The time to disappearance/improvement of chest tightness, shortness of breath, cough, and moist rales in both groups were recorded. The levels of brain natriuretic peptide (BNP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and procalcitonin (PCT) were measured before and after treatment. Changes in cardiac function were observed, and the Clinical Pulmonary Infection Score (CPIS) and Sequential Organ Failure Assessment (SOFA) were used to assess PI. The clinical efficacy and adverse reactions were evaluated after treatment. Follow-up lasted 2 years, during which the readmission rate due to HF and mortality rate were calculated. RESULTS: Patients in the study group experienced a shorter time to disappearance/improvement of chest tightness, shortness of breath, cough, and moist rales compared to the control group (all P<0.05). The study group also showed reduced levels of BNP, IL-6, TNF-α, and PCT, as well as lower CPIS and SOFA scores after treatment (all P<0.05), with significantly improved cardiac function (P<0.05). Additionally, the total effective rate was higher in the study group than in the control group (P<0.05), and there was no significant difference in adverse reactions between the two groups (P>0.05). Follow-up revealed no difference in mortality between the two groups (P>0.05), but the study group had a lower readmission rate (P<0.05). CONCLUSION: SVST is effective in treating HF complicated by PI, ensures a good prognosis for patients, and is recommended for clinical use.

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.
