RESUMO

BACKGROUND: Heart failure is a common and severe condition, often complicated by diastolic dysfunction. Current standard therapies such as ACEIs and ARBs have limited efficacy in managing diastolic function. Sacubitril/Valsartan, an emerging therapy, warrants rigorous investigation to elucidate its impact on diastolic function in heart failure patients. METHODS: This systematic review and meta-analysis were conducted adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and utilized the PICO schema. Searches were performed on 4 databases-PubMed, Embase, Web of Science, and Cochrane Library-without temporal restrictions. Inclusion and exclusion criteria were strictly defined, and quality assessments were conducted using the Cochrane Collaboration Risk of Bias tool. Both fixed-effects and random-effects models were used for statistical analysis, depending on inter-study heterogeneity assessed by I2 statistics and Chi-square tests. RESULTS: Out of 1129 identified publications, 8 studies met the criteria and were included in the meta-analysis. These studies consisted of both randomized controlled trials and cohort studies and featured diverse global populations. Significant reductions were found in the echocardiographic parameter E/e' ratio and LAVi upon treatment with Sacubitril/Valsartan compared to standard therapies, with mean differences of -1.38 and -4.62, respectively, both with P values < .01. CONCLUSIONS: This meta-analysis demonstrates that Sacubitril/Valsartan significantly improves diastolic function parameters in heart failure patients compared to standard treatments. These findings underscore the potential benefits of Sacubitril/Valsartan in the management of heart failure, particularly for patients with diastolic dysfunction.

RESUMO

BACKGROUND: The first angiotensin receptor/neprilysin inhibitor on the market, sacubitril-valsartan, has shown marked improvements in death and hospitalization for heart failure among adults, and is now approved for use in pediatric heart failure. While the ongoing PANORAMA-HF trial is evaluating the effectiveness of sacubitril-valsartan for pediatric patients with a failing systemic left ventricle, the enrollment criteria do not include the majority of pediatric heart failure patients. Additional studies are needed. METHODS: Using the TriNetX database, we performed a propensity score matched, retrospective cohort study to assess the incidence of a composite of all-cause mortality or heart transplant within 1 year. The 519 patients who received sacubitril-valsartan were compared to 519 matched controls who received an angiotensin converting enzyme inhibitor (ACE) or angiotensin II receptor blocker (ARB). RESULTS: There was no significant difference in the incidence of the composite outcome with sacubitril-valsartan over an ACE/ARB (13.3% vs 13.2%, p = 0.95), or among the components of mortality (5.0% vs 5.8%, p = 0.58) or heart transplantation (8.7% vs 7.5%, p = 0.50). Patients who were receiving full goal-directed medical therapy (14.4% vs 16.0%, p = 0.55) also showed no difference in the composite outcome. We observed a significantly increased incidence of hypotension (10% vs 5.2%, p = 0.006) and a trend toward reduced number of hospitalizations per year (mean (SD) 1.3 (4.4) vs 2.0 (9.1), p = 0.09). CONCLUSIONS: Sacubitril-valsartan is not associated with a decrease in the composite of all-cause mortality or heart transplantation within 1 year. Future studies should evaluate the possible reduction in hospitalizations and optimal dosing to minimize hypotension.

RESUMO

This study focuses on the purification and detection of glufosinate (GLUF) and its metabolites N-acetyl GLUF and MPP in plasma samples. A Dikma Polyamino HILIC column was used for the effective retention and separation of GLUF and its metabolites, and the innovative addition of a low concentration of ammonium fluoride solution to the mobile phase effectively improved the detection sensitivity of the target analytes. Monodisperse core-shell weak cation exchange (WCX)/C18 bifunctional magnetic polymer composites (Fe3O4@WCX/C18) were prepared in a controllable manner, and their morphology and composition were fully characterized. The Fe3O4@WCX/C18 microspheres were used as a magnetic solid-phase extraction (MSPE) adsorbent for the sample purification and detection of GLUF and its metabolites in plasma samples combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS). The purification conditions of Fe3O4@WCX/C18 microspheres for GLUF and its metabolites in spiked plasma samples were optimized to achieve the best MSPE efficiency. The purification mechanisms of the target analytes in plasma samples include electrostatic attraction and hydrophobic interactions. Furthermore, the effect of the molar ratio of the two functional monomers 4-VBA and 1-octadecene in the adsorbent was optimized and it shows that the bifunctional components WCX/C18 have a synergistic effect on the determination of GLUF and its metabolites in plasma samples. In addition, the present study compared the purification performance of the Fe3O4@WCX/C18 microsphere-based MSPE method with that of the commercial Oasis WCX SPE method, and the results showed that the Fe3O4@WCX/C18 microsphere-based MSPE method established in this work had a stronger ability to remove matrix interferences. Under optimal purification conditions, the recoveries of GLUF and its metabolites in plasma were 87.6-111 % with relative standard deviations (RSDs) ranging from 0.2 % to 4.8 %. The limits of detection (LODs, S/N≥3) and limits of quantification (LOQs, S/N≥10) were 0.10-0.18 µg/L and 0.30-0.54 µg/L, respectively. The MSPE-LC-MS/MS method developed in this study is fast, simple, accurate and sensitive and can be used to confirm GLUF intoxication based not only on the detection of the GLUF prototype but also on the detection of its two metabolites.

RESUMO

BACKGROUND: An angiotensin receptor-neprilysin inhibitor (ARNI) is the preferred renin-angiotensin system (RAS) inhibitor for heart failure with reduced ejection fraction (HFrEF). Among eligible patients, insurance status and prescriber concern regarding out-of-pocket costs may constrain early initiation of ARNI and other new therapies. OBJECTIVES: In this study, the authors sought to evaluate the association of insurance and other social determinants of health with ARNI initiation at discharge from HFrEF hospitalization. METHODS: The authors analyzed ARNI initiation from January 2017 to June 2020 among patients with HFrEF eligible to receive RAS inhibitor at discharge from hospitals in the Get With The Guidelines-Heart Failure registry. The primary outcome was the proportion of ARNI prescription at discharge among those prescribed RAS inhibitor who were not on ARNI on admission. A logistic regression model was used to determine the association of insurance status, U.S. region, and their interaction, as well as self-reported race, with ARNI initiation at discharge. RESULTS: From 42,766 admissions, 24,904 were excluded for absolute or relative contraindications to RAS inhibitors. RAS inhibitors were prescribed for 16,817 (94.2%) of remaining discharges, for which ARNI was prescribed in 1,640 (9.8%). Self-reported Black patients were less likely to be initiated on ARNI compared to self-reported White patients (OR: 0.64; 95% CI: 0.50-0.81). Compared to Medicare beneficiaries, patients with third-party insurance, Medicaid, or no insurance were less likely to be initiated on ARNI (OR: 0.47 [95% CI: 0.31-0.72], OR: 0.41 [95% CI: 0.25-0.67], and OR: 0.20 [95% CI: 0.08-0.47], respectively). ARNI therapy varied by hospital region, with lowest utilization in the Mountain region. An interaction was demonstrated between the impact of insurance disparities and hospital region. CONCLUSIONS: Among patients hospitalized between 2017 and 2020 for HFrEF who were prescribed RAS inhibitor therapy at discharge, insurance status, geographic region, and self-reported race were associated with ARNI initiation.

RESUMO

In forensic science, glyphosate (GLYP) and glufosinate (GLUF), a class of non-selective broad-spectrum herbicides, have been frequently encountered in many fatal poisoning and suicide cases due to their widespread availability. Therefore, it is essential to develop an effective method for detecting these compounds. Some conventional methods, such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS), have been reported to detect these compounds. However, these methods are not ideal for their time-consuming and non-sensitive feature. Herein, probe electrospray ionization (PESI) tandem mass spectrometry (MS/MS), a fast and sensitive technique, was applied for the determination of GLYP and GLUF in human blood, which can obtain analytical results within 0.5 min without derivatization and chromatographic separation. After protein precipitation of blood samples, the supernatant was mixed with isopropanol and ultra-pure water (1:1 v/v). Then, 8 µL of the mixture was introduced into the plastic sample plate for PESI-MS/MS analysis. The limits of detection (LODs) of the method were 0.50 µg/mL and 0.25 µg/mL for two analytes, and the limits of quantitation (LOQs) were both 1.00 µg/mL, which are higher than the concentration of reported poisoning and fatal cases. In the linear range of 1-500 µg/mL, the regression coefficients (r2) for GLYP and GLUF were over 0.99. The matrix effects ranged from 94.8 % to 119.5 %, and the biases were below 4.3 %. The recoveries ranged between 84.8 % and 107.4 %, and the biases were below 7.6 %. Meanwhile, the method was effectively utilized to detect and quantify the blood, urine, and other samples. Consequently, the results suggest that PESI-MS/MS is a straightforward, fast, and sensitive method for detecting GLUF and GLYP in forensics. In the future, PESI-MS/MS will become an indispensable technique for polar substances in grassroots units of public security where rapid detection is essential.

RESUMO

Organophosphorus pesticides play an important role as broad-spectrum inactivating herbicides in agriculture. Developing a method for rapid and efficient organophosphorus pesticides detection is still urgent due to the increasing concern on food safety. An organo-probe (ZDA), synthesized by purine hydrazone derivative and 2,2'-dipyridylamine derivative, was applied in sensitive recognition of Cu2+ with detection limit of 300 nM. Mechanism study via density functional theory (DFT) and job's plot experiment revealed that ZDA and Cu2+ ions form a 1:2 complex quenching the fluorescence emission. Moreover, this fluorescent complex ZDA-Cu2+ was applicable for detecting glyphosate and glufosinate ammonium following fluorescence enhancement mechanism, with detection limits of 11.26 nM and 11.5 nM, respectively. Meanwhile, ZDA-Cu2+ was effective and sensitive when it is used for pesticide detection, reaching the maximum value and stabilizing in 1 min. Finally, the ZDA-Cu2+ probe could also be tolerated in cell assay environment, implying potential bio-application.

RESUMO

Glufosinate-ammonium herbicides are the most widely used broad-spectrum, non-selective herbicides in the world. Glufosinate-ammonium is a structural analogue of glutamate (Glu) which can irreversibly inhibit the activity of glutamine synthetase (GS) and Glu decarboxylase in plants, thereby blocking the synthesis of glutamine (Gln) from Glu and ammonia (Hoerlein, 1994). This causes the plants to die because of the nitrogen metabolism disorder and subsequent intracellular accumulation of ammonia. In humans, the characteristic features of glufosinate-ammonium herbicide poisoning include gastrointestinal symptoms and neurotoxicity (Watanabe and Sano, 1998). Currently, there are no antidotes for glufosinate-ammonium herbicide poisoning, and thus supportive care is the key treatment.

RESUMO

BACKGROUND/AIM: Sacubitril/valsartan (SV), a novel pharmacological class of angiotensin receptor neprilysin inhibitors, is effective in treating heart failure (HF) by inhibiting the degradation of natriuretic peptides and the renin-angiotensin-aldosterone system. However, no studies have observed the long-term effects of SV on patients with HF and preserved left ventricular ejection fraction (LVEF) undergoing hemodialysis (HD) over a long period. PATIENTS AND METHODS: This single-center retrospective study of 21 months duration involved consecutive patients with HF and preserved LVEF undergoing HD, who received 50-200 mg/day. All patients were followed up regularly, and clinical, biochemical, and echocardiographic parameters were recorded at baseline and during follow-up. The efficacy and safety of SV were also analyzed. RESULTS: This longitudinal study included nine patients, with a median age of 76 years. The median HD duration was 7 years. At baseline, the mean brain natriuretic peptide (BNP) was 133±73.6 pg/ml and that of LVEF was 66%±9%. After SV therapy, the systolic blood pressure, diastolic blood pressure, and heart rate decreased, albeit without statistical significance. BNP levels, LVEF, left atrial anteroposterior dimension, and left ventricular mass index did not change, compared to baseline values. No adverse effects were observed in any of the patients. CONCLUSION: SV tended to decrease blood pressure and heart rate in patients with HF and preserved LVEF undergoing HD but did not alter cardiac function assessments, such as BNP or echocardiography.

RESUMO

INTRODUCTION: The efficacy of sacubitril/valsartan versus olmesartan remains controversial for the control of hypertension. We conduct a systematic review and meta-analysis to explore the influence of sacubitril/valsartan versus olmesartan on the control of hypertension. METHODS: We have searched PubMed, Embase, Web of science, EBSCO, and Cochrane library databases through July 2023 for randomized controlled trials assessing the effect of sacubitril/valsartan versus olmesartan on the control of hypertension. This meta-analysis is performed using the random-effect model or fixed-effect model based on the heterogeneity. RESULTS: Seven randomized controlled trials and 3677 patients were included in the meta-analysis. Overall, compared with olmesartan treatment for hypertension, sacubitril/valsartan treatment was associated with substantially decreased systolic blood pressure (mean difference [MD] = -4.58; 95% confidence interval [CI] = -7.90 to -1.25; P = .007), diastolic blood pressure (MD = -1.70; 95% CI = -3.24 to -0.17; P = .03), and pulse pressure (MD = -2.31; 95% CI = -4.41 to -0.21; P = .03), as well as improved systolic blood pressure control (odds ratio [OR] = 1.65; 95% CI = 1.15 to 2.38; P = .006), but had no influence on diastolic blood pressure control (OR = 1.33; 95% CI = 0.93 to 1.88; P = .11) or adverse events (OR = 1.06; 95% CI = 0.90 to 1.24; P = .51). CONCLUSIONS: Sacubitril/valsartan is better than olmesartan for the reduction of blood pressure for patients with hypertension.

RESUMO

Renal artery stenosis can complicate the management of heart failure with reduced ejection fraction, as it is a conventional contraindication to the use of ACE inhibitors. We report a case in which bilateral renal artery revascularisation allowed the safe reintroduction of enalapril (and subsequently sacubitril valsartan) in a patient with severe left ventricular systolic dysfunction. There is a role for renal artery angioplasty in selected patients to allow optimal medical therapy for patients with heart failure due to impaired systolic function.

RESUMO

Studies have shown that Sacubitril/valsartan (Sac/Val) can reduce myocardial inflammation in myocarditis mice, in addition to its the recommended treatment of heart failure. However, the underlying mechanisms of Sac/Val in myocarditis remain unclear. C-type natriuretic peptide (CNP), one of the targeting natriuretic peptides of Sac/Val, was recently reported to exert cardio-protective and anti-inflammatory effects in cardiovascular systems. Here, we focused on circulating levels of CNP in patients with acute myocarditis (AMC) and whether Sac/Val modulates inflammation by targeting CNP in experimental autoimmune myocarditis (EAM) mice as well as LPS-induced RAW 264.7 cells and bone marrow derived macrophages (BMDMs) models. Circulating CNP levels were higher in AMC patients compared to healthy controls, and these levels positively correlated with the elevated inflammatory cytokines IL-6 and monocyte count. In EAM mice, Sac/Val alleviated myocardial inflammation while augmenting circulating CNP levels rather than BNP and ANP, accompanied by reduction in intracardial M1 macrophage infiltration and expression of inflammatory cytokines IL-1ß, TNF-α, and IL-6. Furthermore, Sac/Val inhibited CNP degradation and directly blunted M1 macrophage polarization in LPS-induced RAW 264.7 cells and BMDMs. Mechanistically, the effects might be mediated by the NPR-C/cAMP/JNK/c-Jun signaling pathway apart from NPR-B/cGMP/NF-κB pathway. In conclusion, Sac/Val exerts a protective effect in myocarditis by increasing CNP concentration and inhibiting M1 macrophages polarization.

RESUMO

We aimed in this study to investigate the possible cardioprotective effects of sacubitril/valsartan against sunitinib-induced cardiac fibrosis (CF) and oxidative stress via targeting thioredoxin-interacting protein/thioredoxin (TXNIP/TRX) system and nuclear factor-kappa B (NF-κB)/Wingless-related MMTV integration site (Wnt)/ß-catenin/Sex-determining region Y box 9 (SOX9) signaling. CF was induced in male Wistar albino rats by cumulative dose of sunitinib (300 mg/kg, given over 4 weeks as: 25 mg/kg orally, three times a week), which were co-treated with sacubitril/valsartan (68 mg/kg/day, orally) for four weeks. Significant elevation in blood pressure, cardiac inflammatory and fibrotic markers besides cardiac dysfunction were observed. These alterations were associated with disruption of TXNIP/TRX system, upregulation of NF-κB/Wnt/ß-catenin/SOX9 pathway along with marked increase in lysyl oxidase (LOX) and matrix metalloproteinase-1 (MMP-1) expressions and extensive deposition of collagen fibers in cardiac tissues. Luckily, sacubitril/valsartan was able to reverse all of the aforementioned detrimental effects in sunitinib-administered rats. These findings illustrate a potential role of sacubitril/valsartan in alleviating CF and oxidative stress induced by sunitinib via antioxidant, anti-inflammatory and antifibrotic properties. These remarkable effects of sacubitril/valsartan were mediated by its ability to improve TXNIP/TRX system and downregulate NF-κB/Wnt/ß-catenin/SOX9 signaling in addition to decreasing LOX and MMP-1 expressions in cardiac tissues. In summary, this study highlights sacubitril/valsartan as a potential therapeutic agent in mitigating CF and oxidative stress especially in cancer cases treated with sunitinib.

RESUMO

BACKGROUND: The efficacy and safety of sacubitril/valsartan in patients hospitalized with heart failure (HF) across the spectrum of left ventricular ejection fraction (EF) has not been described. OBJECTIVES: Data from randomized trials of sacubitril/valsartan in HF patients with EF ≤40% (PIONEER-HF [Comparison of Sacubitril/Valsartan Versus Enalapril on Effect of NT-proBNP in Patients Stabilized From an Acute Heart Failure Episode] trial) and >40% (PARAGLIDE-HF [Prospective comparison of ARNI with ARB Given following stabiLization In DEcompensated HFpEF] trial) following recent worsening heart failure (WHF) were pooled to examine treatment effect across the EF spectrum. METHODS: The PIONEER-HF and PARAGLIDE-HF trials were double-blind, randomized trials of sacubitril/valsartan vs control therapy (enalapril or valsartan, respectively). All participants in the PIONEER-HF trial and 69.5% in the PARAGLIDE-HF trial were enrolled during hospitalization for HF after stabilization. The remainder in the PARAGLIDE-HF trial were enrolled ≤30 days after a WHF event. The primary endpoint of both trials was time-averaged proportional change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) from baseline through weeks 4 and 8. Adjudicated clinical endpoints were analyzed through the end of follow-up, adjusting for trial. RESULTS: The pooled analysis included 1,347 patients (881 from PIONEER-HF, 466 from PARAGLIDE-HF). Baseline characteristics included median age 66 years, 36% women, 31% Black, 34% de novo HF, and median EF 30%. The reduction in NT-proBNP was 24% greater with sacubitril/valsartan vs control therapy (n = 1,130; ratio of change = 0.76; 95% CI: 0.69-0.83; P < 0.0001). Cardiovascular death or hospitalization for HF was reduced by 30% with sacubitril/valsartan vs control therapy (HR: 0.70; 95% CI: 0.54-0.91; P = 0.0077). This effect was consistent across the spectrum of EF ≤60%. Sacubitril/valsartan increased symptomatic hypotension (risk ratio: 1.35; 95% CI: 1.05-1.72). CONCLUSIONS: In patients stabilized after WHF, sacubitril/valsartan led to a greater reduction in plasma NT-proBNP and improved clinical outcome compared with control therapy, in particular across the spectrum of EF ≤60%.

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.

RESUMO

Diquat (DQ), paraquat (PQ), glufosinate (GLU), and glyphosate (GLYP) are commonly used herbicides that have been confirmed to be toxic to humans. Rapid and accurate measurements of these toxicants in clinical practice are beneficial for the correct diagnosis and timely treatment of herbicide-poisoned patients. The present study aimed to establish an efficient, convenient, and reliable method to achieve the simultaneous quantification of DQ, PQ, GLU, and GLYP in human plasma using liquid chromatography-tandem mass spectrometry (LC-MS/MS) without using derivatization or ion-pairing reagents. DQ, PQ, GLU, and GLYP were extracted by the rapid protein precipitation and liquid-liquid extraction method and then separated and detected by LC-MS/MS. Subsequently, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, extraction recovery, matrix effect, dilution integrity, and stability were evaluated to validate the method based on the FDA criteria. Finally, the validated method was applied to real plasma samples collected from 166 Chinese patients with herbicide poisoning. The results showed satisfactory linearity with low LOD (1 ng/mL for DQ and PQ, 5 ng/mL for GLU, and 10 ng/mL for GLYP, respectively) and low LOQ (5 ng/mL for DQ and PQ, 25 ng/mL for GLU and GLYP, respectively). In addition, the precision, accuracy, extraction recovery, and stability of the method were acceptable. The matrix effect was not observed in the analyzed samples. Moreover, the developed method was successfully applied to determine the target compounds in real plasma samples. These data provided reliable evidence for the application of this LC-MS/MS method for clinical poisoning detection.

RESUMO

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.

RESUMO

AIM: To evaluate the impact of frailty syndrome (FS) on the course of acute decompensated heart failure (ADHF) and the quality of drug therapy before discharge from the hospital in patients with reduced and moderately reduced left ventricular ejection fraction (LVEF). MATERIAL AND METHODS: This open prospective study included 101 patients older than 75 years with reduced and mid-range LVEF hospitalized for decompensated chronic heart failure (CHF). FS was detected during the outpatient follow-up and identified using the Age is Not a Hindrance questionnaire, the chair rise test, and the One Leg Test. The "fragile" group consisted of 54 patients and the group without FS included 47 patients. Clinical characteristics of patients were compared, and the prescribing rate of the main drugs for the treatment of CHF was assessed upon admission to the hospital. The sacubitril/valsartan or dapagliflozin therapy was initiated in the hospital; prescribing rate of the quadruple therapy was assessed upon discharge from the hospital. Patients with reduced LVEF were followed up for 30 days, and LVEF was re-evaluated to reveal possible improvement due to optimization of therapy during hospitalization. Statistical analysis was performed with the SPSS 23.0 software. RESULTS: The main causes for decompensation did not differ in patients of the compared groups. According to the correlation analysis, FS was associated with anemia (r=0.154; p=0.035), heart rate ≥90 bpm (r=0.185; p=0.020), shortness of breath at rest (r =0.224; p=0.002), moist rales in the lungs (r=0.153; p=0.036), ascites (r=0.223; p=0.002), increased levels of the N-terminal pro-brain natriuretic peptide (NT-proBNP) (r= 0.316; p<0.001), hemoglobin concentration <120 g / l (r=0.183; p=0.012), and total protein <65 g / l (r=0.153; p=0.035) as measured by lab blood tests. Among patients with LVEF ≤40 % in the FS group (n=33) and without FS (n=33), the quadruple therapy was a part of the treatment regimen at discharge from the hospital in 27.3 and 3.0 % of patients, respectively (p=0.006). According to the 30-day follow-up data, improvement of LVEF was detected in 18.2% of patients with LVEF ≤40% in the FS group and 12.1% of patients with LVEF ≤40% in the FS-free group (p=0.020). In patients with LVEF 41-49 % in the FS (n=21) and FS-free (n=14) groups, the prescribing rate of the optimal therapy, including sacubitril/valsartan, sodium-glucose cotransporter 2 inhibitors, beta-blockers, and mineralocorticoid receptor antagonists, no statistically significant differences were detected (14.3 and 7.1 %, respectively; p=0.515) at discharge from the hospital. CONCLUSION: Patients with ADHF and FS showed more pronounced clinical manifestations of decompensation, anemia, heart rate ≥90 beats/min, and higher levels of NT-proBNP upon admission. The inpatient therapy with sacubitril/valsartan or dapagliflozin was more intensively initiated in FS patients with reduced LVEF. An individualized approach contributed to achieving a prescribing rate of sacubitril/valsartan of 39.4%, dapagliflozin of 39.4%, and quadruple therapy of 27.3% upon discharge from the hospital.

RESUMO

Sacubitril/Valsartan, the combination of angiotensin receptor inhibitor and neprilysin inhibitor, is now becoming the class 1 recommendation for HFrEF. Some studies have shown the positive effect of Sacubitril/Valsartan on HFrEF cancer patients, while there is devoid of evidence about the effect of this drug in aged cancer patients with HFmrEF and HFpEF. By searching the patients with a diagnosis of both cancer and Heart failure (HF) over 65, the patients who had received treatment with Sacubitril/Valsartan were selected as the candidates for Sacubitril/Valsartan group, and the patients who had received conventional HF therapy without Sacubitril/Valsartan were chosen as the control group. Data were collected for up to 9 months. We filtered 38 patients and 50 patients valid for Sacubitril/Valsartan group and control group, respectively. After initiation of heart failure management, our study found a better cardiac condition in Sacubitril/Valsartan group, having better LVEF, LVFS, NT-proBNP in 3rd, 6th, 9th month (P < .05) and better NYHA function classification after the treatment. We also observed fewer cases of deterioration on LAD (P = .029) and LVEDD (P = .023) in Sacubitril/Valsartan group. In subgroup analysis, our study showed that all 3 kinds of HF patients had better LVEF, LVFS, and NT-proBNP in Sacubitril/Valsartan group (P < .05). Our study further indicated that Sacubitril/Valsartan can improve cardiac function and benefit cardiac remolding in aged cancer patients of all 3 kinds of HF. This is the first study to provide new evidence for the use of Sacubitril/Valsartan in aged cancer patients of 3 kinds of HF.

RESUMO

BACKGROUND: Hypotension is a potential adverse effect of sacubitril/valsartan, but there are limited data regarding the predictors and implications of treatment-related hypotension in heart failure (HF) with mildly reduced and preserved ejection fraction. OBJECTIVES: We investigated predictors of treatment-associated hypotension, clinical outcomes after hypotension, and the relationship between left ventricular ejection fraction (LVEF) and incidence of hypotension in the PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction) trial. METHODS: PARAGON-HF randomized patients with chronic HF (≥45%) to sacubitril/valsartan or valsartan. Following randomization, hypotension was defined as investigator-reported hypotension with a systolic blood pressure <100 mm Hg. Predictors of hypotension were assessed using multivariable Cox models. Associations between hypotension and clinical outcomes were evaluated in time-updated Cox models. The relationship among treatment, LVEF, and incident rates of hypotension and clinical outcomes was estimated using Poisson regression models. RESULTS: Of 4,796 patients in PARAGON-HF, 637 (13%) experienced hypotension, more frequently in the sacubitril/valsartan arm (P < 0.001). Following documented hypotension, patients had higher risk of cardiovascular death and total HF hospitalizations (adjusted RR: 1.63; 95% CI: 1.27-2.09; P < 0.001) and all-cause death (adjusted HR: 1.62; 95% CI: 1.28-2.05; P < 0.001). LVEF modified the association between sacubitril/valsartan and risk of hypotension (Pinteraction = 0.019) such that patients with LVEF ≥60% experienced substantially higher treatment-related risks of hypotension. CONCLUSIONS: In PARAGON-HF, a higher LVEF was associated with an increased risk of hypotension in patients treated with sacubitril/valsartan compared with valsartan. Because these subjects are also less likely to derive clinical benefit from sacubitril/valsartan, our data reinforce that the benefit/risk ratio favors the use of sacubitril/valsartan in patients with LVEF below normal, but not at higher LVEF.
