ABSTRACT
This study aimed to evaluate the efficacy of nifedipine controlled-release tablets combined with sacubitril valsartan in diabetic nephropathy (DN) patients with hypertension. One hundred and twelve DN patients with hypertension were enrolled. They were randomly divided into the control group (treated with nifedipine controlled-release tablets combined with valsartan) and the observation group (treated with nifedipine controlled-release tablets combined with sacubitril valsartan). Renal function, endothelial function and inflammatory response were examined. After three-months treatment, the levels of clinical indexes (glycosylated hemoglobin, fasting blood glucose, systolic and diastolic blood pressure), renal function indicators (urinary albumin excretion rate, blood urea nitrogen, serum creatinine and cystatin C), endothelial function indicators (microalbumin, angiotensin II, thrombomodulin and cartilage oligomeric matrix protein) and inflammatory response factors (interleukin-6 and tumor necrosis factor-α) in the observation group were significantly lower than those in the control group. Nifedipine controlled-release tablets combined with sacubitril valsartan could effectively alleviate the progression of DN combined with hypertension.

PURPOSE: Sacubitril/valsartan is a mainstay of the treatment of heart failure with reduced ejection fraction (HFrEF); however, its effects on exercise performance yielded conflicting results. Aim of our study was to evaluate the impact of sacubitril/valsartan on exercise parameters and echocardiographic and biomarker changes at different drug doses. METHODS: We prospectively enrolled consecutive HFrEF outpatients eligible to start sacubitril/valsartan. Patients underwent clinical assessment, cardiopulmonary exercise test (CPET), blood sampling, echocardiography, and completed the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Sacubitril/valsartan was introduced at 24/26 mg b.i.d. dose and progressively uptitrated in a standard monthly-based fashion to 97/103 mg b.i.d. or maximum tolerated dose. Study procedures were repeated at each titration visit and 6 months after reaching the maximum tolerated dose. RESULTS: Ninety-six patients completed the study, 73 (75%) reached maximum sacubitril/valsartan dose. We observed a significant improvement in functional capacity across all study steps: oxygen intake increased, at peak exercise (from 15.6 ± 4.5 to 16.5 ± 4.9 mL/min/kg; p trend = 0.001), while minute ventilation/carbon dioxide production relationship reduced in patients with an abnormal value at baseline. Sacubitril/valsartan induced positive left ventricle reverse remodeling (EF from 31 ± 5 to 37 ± 8%; p trend < 0.001), while NT-proBNP reduced from 1179 [610-2757] to 780 [372-1344] pg/ml (p trend < 0.0001). NYHA functional class and the subjective perception of limitation in daily life at KCCQ-12 significantly improved. The Metabolic Exercise Cardiac Kidney Index (MECKI) score progressively improved from 4.35 [2.42-7.71] to 2.35% [1.24-4.96], p = 0.003. CONCLUSIONS: A holistic and progressive HF improvement was observed with sacubitril/valsartan in parallel with quality of life. Likewise, a prognostic enhancement was observed.

Heart failure (HF) remains one of the most common causes of hospitalization and mortality among Polish patients. The position of the Section of Cardiovascular Pharmacotherapy presents the currently applicable options for pharmacological treatment of HF based on the latest European and American guidelines from 2021-2022 in relation to Polish healthcare conditions. Treatment of HF varies depending on its clinical presentation (acute/chronic) or left ventricular ejection fraction. Initial treatment of symptomatic patients with features of volume overload is based on diuretics, especially loop drugs. Treatment aimed at reducing mortality and hospitalization should include drugs blocking the renin-angiotensin-aldosterone system, preferably angiotensin receptor antagonist/neprilysin inhibitor, i.e. sacubitril/valsartan, selected beta-blockers (no class effect - options include bisoprolol, metoprolol succinate, or vasodilatory beta-blockers - carvedilol and nebivolol), mineralocorticoid receptor antagonist, and sodium-glucose cotransporter type 2 inhibitor (flozin), constituting the 4 pillars of pharmacotherapy. Their effectiveness has been confirmed in numerous prospective randomized trials. The current HF treatment strategy is based on the fastest possible implementation of all four mentioned classes of drugs due to their independent additive action. It is also important to individualize therapy according to comorbidities, blood pressure, resting heart rate, or the presence of arrhythmias. This article emphasizes the cardio- and nephroprotective role of flozins in HF therapy, regardless of ejection fraction value. We propose practical guidelines for the use of medicines, profile of adverse reactions, drug interactions, as well as pharmacoeconomic aspects. The principles of treatment with ivabradine, digoxin, vericiguat, iron supplementation, or antiplatelet and anticoagulant therapy are also discussed, along with recent novel drugs including omecamtiv mecarbil, tolvaptan, or coenzyme Q10 as well as progress in the prevention and treatment of hyperkalemia. Based on the latest recommendations, treatment regimens for different types of HF are discussed.

Diabetic nephropathy (DN) is the most important cause of chronic renal and end-stage kidney disease in China. Hypertension (HTN) is highly prevalent in individuals with diabetic nephropathy. Arterial HTN affects two-thirds of people with type 2 diabetes (T2D). In these patients, HTN increased the potential of both micro- and macrovascular complications, and the co-occurrence of 2 such principal causes results in a 4-fold increased risk for cardiovascular disease (CVD) when contrasted with normotensive controls without diabetes. Therefore, the results of valsartan and amlodipine tablets combined with alpha-lipoic acid on total antioxidant capacity (T-AOC) need to be investigated. The aim of this study was to analyze the effects of valsartan (VA) and amlodipine tablets combined with alpha-lipoic acid (α-LA) on T-AOC, IL-6 and ß2-MG levels in patients with DN. We performed statistical analysis including the chi-square test, independent t-test, paired t-test and Analysis of Variance (ANOVA). Our findings indicate that VA, amlodipine and α-LA has a significant effect in patients with DN.

ETHNOPHARMACOLOGICAL RELEVANCE: Qingda granule (QDG) exhibits significant therapeutic effects on high blood pressure, vascular dysfunction, and elevated proliferation of vascular smooth muscle cells by inhibiting multiple pathways. However, the effects and underlying mechanisms of QDG treatment on hypertensive vascular remodeling are unclear. AIM OF THE STUDY: The aim of this study was to determine the role of QDG treatment in hypertensive vascular remodeling in vivo and in vitro. MATERIALS AND METHODS: An ACQUITY UPLC I-Class system coupled with a Xevo XS quadrupole time of flight mass spectrometer was used to characterize the chemical components of QDG. Twenty-five spontaneously hypertensive rats (SHR) were randomly divided into five groups, including SHR (equal volume of double distilled water, ddH2O), SHR + QDG-L (0.45 g/kg/day), SHR + QDG-M (0.9 g/kg/day), SHR + QDG-H (1.8 g/kg/day), and SHR + Valsartan (7.2 mg/kg/day) groups. QDG, Valsartan, and ddH2O were administered intragastrically once a day for 10 weeks. For the control group, ddH2O was intragastrically administered to five Wistar Kyoto rats (WKY group). Vascular function, pathological changes, and collagen deposition in the abdominal aorta were evaluated using animal ultrasound, hematoxylin and eosin and Masson staining, and immunohistochemistry. Isobaric tags for relative and absolute quantification (iTRAQ) was performed to identify differentially expressed proteins (DEPs) in the abdominal aorta, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed. Cell Counting Kit-8 assays, phalloidin staining, transwell assays, and western-blotting were performed to explore the underlying mechanisms in primary isolated adventitial fibroblasts (AFs) stimulated with transforming growth factor-ß 1 (TGF-ß1) with or without QDG treatment. RESULTS: Twelve compounds were identified from the total ion chromatogram fingerprint of QDG. In the SHR group, QDG treatment significantly attenuated the increased pulse wave velocity, aortic wall thickening, and abdominal aorta pathological changes and decreased Collagen I, Collagen III, and Fibronectin expression. The iTRAQ analysis identified 306 DEPs between SHR and WKY and 147 DEPs between QDG and SHR. GO and KEGG pathway analyses of the DEPs identified multiple pathways and functional processes involving vascular remodeling, including the TGF-ß receptor signaling pathway. QDG treatment significantly attenuated the increased cell migration, actin cytoskeleton remodeling, and Collagen I, Collagen III, and Fibronectin expression in AFs stimulated with TGF-ß1. QDG treatment significantly decreased TGF-ß1 protein expression in abdominal aortic tissues in the SHR group and p-Smad2 and p-Smad3 protein expression in TGF-ß1-stimulated AFs. CONCLUSIONS: QDG treatment attenuated hypertension-induced vascular remodeling of the abdominal aorta and phenotypic transformation of adventitial fibroblasts, at least partly by suppressing TGF-ß1/Smad2/3 signaling.

INTRODUCTION: Heart failure (HF) patients discharged from a hospital are at a high risk of death and rehospitalization. Scarce data are available on the use of sacubitril / valsartan in this population in Poland. OBJECTIVE: The aim of this study was to compare the efficacy and tolerability of sacubitril / valsartan in the group of Polish patients who participated in the TRANSITION study with the patients recruited at other sites. PATIENTS AND METHODS: This is a post hoc secondary analysis of the TRANSITION study comparing sacubitril / valsartan initiation pre- vs postdischarge in 991 patients hospitalized for acute decompensated HF with reduced ejection fraction (HFrEF). The Polish subgroup consisted of 104 patients. RESULTS: Significant differences were identified in the characteristics of Polish vs nonPolish populations. At baseline, the Polish population showed higher proportion of men, higher body mass index, lower heart rate, Nterminal pro-Btype natriuretic peptide and highsensitivity troponin T levels, and significantly lower New York Heart Association class. The Polish patients were better managed in terms of implanted electrotherapy devices, percutaneous coronary interventions, and drug therapy, and were more often hospitalized. The primary end point of achieving the target dose of sacubitril / valsartan at treatment week 10 was met by 45.6% of the Polish patients and 48.4% of the nonPolish population (P = 0.61). Approximately 90% of the Polish patients received and maintained any sacubitril / valsartan dose for 2 weeks over 10week treatment vs 87.5% of the nonPolish patients (P = 0.36). The rate of permanent sacubitril / valsartan treatment discontinuation was low in both Polish (3.9%) and nonPolish populations (6.4%) (P = 0.33). CONCLUSIONS: Sacubitril / valsartan can be used safely in the early period after an episode of acute HF both in the Polish and nonPolish patients with HFrEF, and the likelihood to achieve the maximum dose is the same despite significant differences between the studied populations.

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.

Finding complementary compelling novel therapeutic agents for better control of blood pressure in people with resistant hypertension is moving into unchartered territory. The latest therapeutic developments explore approaches in the clinical arena that were either not examined or could only be examined in animal models two decades ago. Four main mechanisms have now been explored and operationalized in drug development: (a) mineralocorticoid receptor blockade using a nonsteroidal structure with many fewer side effects, (b) an aminopeptidase A inhibitor that has central effects on vasopressin, (c) a combined endothelin A and B receptor blocker and (d) an aldosterone synthase inhibitor devoid of glucocorticoid activity. All these agents are either completing Phase II development and starting Phase III or are involved in the ongoing recruitment of Phase III trials. Additionally, novel agents use antisense inhibition to block angiotensinogen development in the liver. These agents are discussed only for completeness, as they are still in Phase II trial development. Last, another agent that was initially being developed as an antihypertensive and once the data were reviewed by the company clearly showed efficacy as a heart failure agent was sacubitril/valsartan, which was ultimately approved. However, there are some discussions about reinvigorating the quest for an indication for hypertension, although no such steps have been formally initiated.

Objective: To explore the effect of Yiqi Huayu Pinggan Zishen recipe combined with valsartan in the treatment of hypertension and its effect on MMP-9, Ang II, and MCP-1. Methods: About 100 patients with hypertension treated in our hospital from March 2020 to April 2021 were enrolled. All patients were arbitrarily assigned to the control group and the study group. The former group was cured with valsartan, and the latter group was cured with Yiqi Huayu Pinggan Zishen recipe combined with valsartan. The curative effect, blood pressure level, renal function index, serum matrix metalloproteinase-9 (MMP-9), monocyte chemoattractant protein-1 (MCP-1), angiotensin II (Ang II) level, traditional Chinese medicine (TCM) syndrome score, and the incidence of adverse reactions were compared. Results: First of all, we compared the curative effects; the study group exhibited remarkably effective in 44 cases and effective in 6 cases, and the effective rate was 100.00%, while in the control group, 24 cases were markedly effective, 16 cases were effective, and 5 cases were ineffective; the effective rate was 90.00%. The curative effect in the study group was higher (P < 0.05). Secondly, we compared the blood pressure level. Before treatment, there was no remarkable difference (P > 0.05). After treatment, the blood pressure of the two groups decreased. The systolic blood pressure and diastolic blood pressure of the study group were lower (P < 0.05). In terms of renal function indexes, the levels of blood urine nitrogen (BUN), Cr, and ß 2-MG in the study group were lower, while the level of eGFR in the study group was higher (P < 0.05). The serum levels of MMP-9, MCP-1, and Ang II decreased. Of note, the levels of serum MMP-9, MCP-1, and Ang II in the study group were lower (P < 0.05). After treatment, the TCM syndrome scores decreased, and the study group was lower (P < 0.05). Finally, we compared the incidence of adverse reactions. The incidence of adverse reactions in the study group was lower (P < 0.05). Conclusion: Yiqi Huayu Pinggan Zishen recipe combined with valsartan in the treatment of hypertension can remarkably reduce the clinical symptoms, enhance the renal function, strengthen the therapeutic effect, promote the ability of independent movement, and reduce the levels of serum MMP-9, MCP-1, and Ang II with high safety, which has the value of clinical application.

The clinical effect of Qili Qiangxin capsule combined with sacubitril-valsartan on patients with chronic heart failure was studied. We selected 108 patients with chronic heart failure in our hospital from March 2016 to January 2020 and divided them into a control group and a study group according to the random table method, with 54 cases in each. The control group took sacubitril and valsartan orally, and the study group took Qili Qiangxin pill on the basis of sacubitril and valsartan. The course of the treatment for 2 groups is 4 weeks. We compared the total effective rate of the treatment of the 2 groups for 4 weeks, cardiac function (left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV), and left ventricular ejection fraction (LVEF)) before and after 4 weeks of treatment, 6 min walking distance (6MWT), changes in cTnI and NT-proBNP levels, and adverse reactions. The total effective rate in the study group (90.74%) is higher than that in the control group (72.22%) (Pï¼0.05). After 4 weeks of treatment, the study group LVESV (45.23 ± 2.98 mm) and LVEDV (43.38 ± 4.01 mm) are lower than those of the control group ((49.98 ± 2.56 mm) and (50.75 ± 3.49 mm), respectively), while LVEF (47.38 ± 2.78%) is higher than that in the control group (42.08 ± 3.24%) (P ï¼ 0.05). After 4 weeks of treatment, the study group 6MWT (476.58 ± 31.25 m) of patients with chronic heart failure is higher than that of the control group (396.52 ± 24.52 m) (P ï¼0.05). After 4 weeks of treatment, the study group serum cTnI (0.36 ± 0.12 µg/L) and NT-proBNP (276.91 ± 30.12 pg/ml) of patients with chronic heart failure are lower than those in the control group (0.87 ± 0.25 µg/L) and (367.48 ± 48.57 pg/ml) (Pï¼0.05). There is no significant difference between the adverse reactions in the two groups (P ï¼ 0.05). Conclusion: Xinbao pills combined with sacubitril and valsartan have a good effect on patients with chronic heart failure, which can improve the heart function and exercise endurance and reduce serum cTnI and NT-proBNP levels.

A model-based meta-analysis quantified comparative dyskalemia risk (hyper- or hypo-kalemia) in hypertensive patients treated with angiotensin receptor blockers (ARBs), a calcium channel blocker (CCB) and/or a thiazide diuretic (hydrochlorothiazide; HCTZ) as monotherapy or as fixed-dose combinations. Among 15 randomized controlled trials in a US Food and Drug Administration regulatory review database, dyskalemia events were reported by five trials (24 treatment arms, 11,030 subjects, 8-week median follow up time). The five trials evaluated monotherapy (ARB or HCTZ) alongside dual (ARB + HCTZ, ARB + CCB, or HCTZ + CCB) or triple fixed-dose combinations (ARB + CCB + HCTZ). Hypo- and hyper-kalemia rates were analyzed jointly to account for correlation. Significant drug class, drug, or dose effects were included in the final model. Effect on various drug- and dose combinations on dyskalemia risk were simulated and compared with model-estimated placebo arm dyskalemia risk. After a typical follow-up of 8 weeks, fixed-dose combinations of ARB with a high dose (25 mg) of HCTZ were associated with a higher hypokalemia risk difference (RD) from placebo (e.g.,Valsartan + HCTZ: 2.52%[95%CIs:1.17, 4.38%]). However, when ARB was combined with a lower, 12.5 mg dose of HCTZ, hypokalemia RD from placebo was not significant (Valsartan + HCTZ: -0.03%[-0.80, 0.71%]). ARB monotherapy raised hyperkalemia RD from placebo (1.3%[0.3, 3.6%]). Hyperkalemia risk was not appreciably higher than placebo for any FDC that combined ARB with HCTZ (Valsartan + HCTZ: 0.06%[-1.48, 1.64%]). In uncomplicated hypertensive patients, ARB + 12.5 mg HCTZ fixed-dose combinations are safer with respect to dyskalemia than either ARB or HCTZ monotherapy for initial antihypertensive treatment.

Heart Failure (HF) is among the major causes of global morbidity as well as mortality. Increased prevalence, frequent and prolonged hospitalization, rehospitalization, long-term consumption of healthcare resources, absenteeism, and death upsurge the economic burden linked to HF. For decades, Angiotensin-Converting Enzyme Inhibitors (ACEIs), Angiotensin II Receptor Blockers (ARBs), Beta-Blockers (BBs), and mineralocorticoid receptor antagonists (MRA), have remained the mainstay of the standard of care for HF management. Despite their proven efficacy and cost-effectiveness, HF remains a global pandemic and is still increasing in prevalence. Sacubitril/ Valsartan (SAC/VAL) is an Angiotensin Receptor/Neprilysin Inhibitor (ARNI) that proved out to be a game-changer drug in HF treatment. Recent data indicated that SAC/VAL is more efficient and can improve the overall quality of life of HF patients with reduced ejection fraction (HFrEF) with fewer side effects. It is now incorporated in the guidelines as an alternative to ACEIs or ARBs to lower morbidity in addition to mortality in HFrEF patients. This review article will discuss the current guidelines-approved indications and highlight the potential emerging indications, in addition to the currently ongoing clinical trials that will expand the use of SAC/VAL.

Chronic kidney disease (CKD) is highly prevalent in patients with chronic heart failure (CHF) and increases the risk of overall and cardiovascular (CV) mortality. Despite evidence supporting the effectiveness of angiotensin-converting enzyme inhibitors (ACE-Is), angiotensin receptor blockers, and mineralocorticoid receptor antagonists in decreasing mortality in patients with CHF, CKD hampers the optimization of standard pharmacologic therapy for heart failure. Therefore, other treatment options are needed to optimize treatment outcomes in CHF patients with CKD. The first-in-class angiotensin receptor-neprilysin inhibitor, sacubitril/valsartan, has a complementary activity that counteracts the potential unwanted long-term effects of over-activation of the renin-angiotensin-aldosterone system. Sacubitril/valsartan reduced the risk of CV mortality compared to standard therapy with an ACE-I in patients with heart failure with reduced ejection fraction (HFrEF) in the PARADIGM-HF trial and has been shown to be safe and effective in a broad range of HFrEF patients. However, data on the efficacy and tolerability of sacubitril/valsartan in patients with more advanced CKD are limited. This review discusses the evidence for the role of sacubitril/valsartan in providing additional renal benefit in patients with HFrEF. Data from clinical trials and real-world experience in patients with HFrEF and advanced CKD support the benefits of dual angiotensin/neprilysin inhibition across the breadth of kidney disease stages, including patients with significant renal impairment that was not reported in the pivotal PARADIGM-HF trial, and suggests a central role for the cardiac benefits of sacubitril/valsartan in nephroprotection.

BACKGROUND: The net clinical benefit of cardiac disease-modifying drugs might be influenced by the interaction of different domains of disease burden. We assessed the relative contribution of cardiac, comorbid, and demographic factors in heart failure (HF) and how their interplay might influence HF prognosis and efficacy of sacubitril/valsartan across the spectrum of left ventricular ejection fraction. METHODS: We combined data from 2 global trials that evaluated the efficacy of sacubitril/valsartan compared with a renin-angiotensin antagonist in symptomatic HF patients (PARADIGM-HF [Prospective Comparison of Angiotensin Receptor Neprilysin Inhibitor With an Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure; n=8399] and PARAGON-HF [Prospective Comparison of Angiotensin-Converting Enzyme Inhibitor With Angiotensin Receptors Blockers Global Outcomes in Heart Failure With Preserved Ejection Fraction; n=4796]). We decomposed the previously validated Meta-Analysis Global Group in Chronic Heart Failure risk score into cardiac (left ventricular ejection fraction, New York Heart Association class, blood pressure, time since HF diagnosis, HF medications), noncardiac comorbid (body mass index, creatinine, diabetes, chronic obstructive pulmonary disease, smoking), and demographic (age, gender) categories. Based on these domains, an index representing the balance of cardiac to noncardiac comorbid burden was created (cardiac-comorbid index). Clinical outcomes were time to first HF hospitalization or cardiovascular deaths and all-cause mortality. RESULTS: Higher scores of the cardiac domain were observed in PARADIGM-HF (10 [7-13] versus 5 [3-6], P<0.001) and higher scores of the demographic domain in PARAGON-HF (10 [8-13] versus 5 [2-9], P<0.001). In PARADIGM-HF, the contribution of the cardiac domain to clinical outcomes was greater than the noncardiac domain (P<0.001), while in PARAGON-HF the attributable risk of the comorbid and demographic categories predominated. Individual scores from each sub-domain were linearly associated with the risk of clinical outcomes (P<0.001). Beneficial effects of sacubitril/valsartan were observed in patients with preponderance of cardiac over noncardiac comorbid burden (cardiac-comorbid index >5 points), suggesting a significant treatment effect modification (interaction P<0.05 for both outcomes). CONCLUSIONS: Domains of disease burden are clinically relevant features that influence the prognosis and treatment of patients with HF. The therapeutic benefits of sacubitril/valsartan vary according to the balance of components of disease burden, across different ranges of left ventricular ejection fraction.

Cardiac fibrosis plays an important role in hypertension-related contractile dysfunction and heart failure. Qingda granule (QDG), derived from the Qingxuan Jiangya decoction, has been used clinically for more than 60 years to treat hypertension. However, the effect of QDG on hypertensive cardiac fibrosis remains largely unknown. The objective of this study was to investigate the effect of QDG on cardiac fibrosis and explore the underlying mechanism in vivo and in vitro. For in vivo experiments, 30 male spontaneously hypertensive rats were randomly divided into groups that received no QDG or one of three doses (0.45, 0.9 or 1.8 g/kg/day). Positive-control animals received valsartan (VAL, 7.2 mg/kg/day). Treatments were administered by gavage for 10 weeks. All three doses of QDG and VAL led to significantly lower blood pressure than in SHR animals. Besides, all three doses of QDG and VAL attenuated pathological changes in SHR animals. However, only intermediate, high concentrations of QDG and VAL led to significantly lower left ventricle ejection fraction and left ventricle fractional shortening than in SHR animals. Therefore, the minimum and effective QDG dose (intermediate concentration of QDG) was selected for subsequent animal experiments in this study. Our results showed that intermediate concentration of QDG also significantly mitigated the increases in levels of α-smooth muscle actin (α-SMA), proliferating cell nuclear antigen (PCNA), collagen III, transforming growth factor-ß1 (TGF-ß1) and in the ratio of phospho-Smad2/3 to total Smad2/3 protein in cardiac tissue, based on immunohistochemistry, Western blotting, and Masson staining. For in vitro experiments, primary cardiac fibroblasts were stimulated with 100 nM angiotensin II in the presence or absence of QDG. And we tested different concentrations of QDG (3.125, 6.25, 12.5, 25, 50 µg/mL) in the cell viability experiment. Our results showed that 3.125, 6.25 and 12.5 µg/mL of QDG treatment for 24 h didn't affect the cell viability of cardiac fibroblasts. Consistently, QDG at 6.25 or 12.5 µg/mL significantly reduced cell viability and down-regulated α-SMA in primary cardiac fibroblasts were stimulated with 100 nM angiotensin II. Therefore, QDG at 12.5 µg/mL was chosen for the following cell experiment. Our results showed that QDG at 12.5 µg/mL alleviated the increase of PCNA, collagen â ¢, TGF-ß1 expression, and the ratio of phospho-Smad2/3 to total Smad2/3 protein. Our studies in vitro and in vivo suggest that QDG reduces blood pressure and cardiac fibrosis as well as protecting cardiac function, and that it exerts these effects in part by suppressing TGF-ß1/Smad2/3 signaling.

BACKGROUND: Widespread use of angiotensin receptor blocker and neprilysin inhibitor (ARNI) remains low, and many patients are unable to tolerate the medication due to hypotension at the currently recommended starting dose. HYPOTHESIS: The aim of this study is to assess if lower than standard doses of ARNI, sacubitril/valsartan (S/V), significantly reduces NT-proBNP and leads to any change in diuretic dose, serum potassium, or creatinine. METHODS: In a retrospective study of 278 patients who were started on a low dose S/V at a single medical center, 45 patients were selected for the study cohort. Patients were subcategorized to Group 1 (n = 10): very low dose S/V (half a tab of 24/26 mg BID), Group 2 (n = 10): very low dose titrated to low dose S/V, and Group 3 (n = 25): low dose S/V (24/26 mg BID). NT-proBNP, diuretic dose, serum potassium, and creatinine were compared before and after initiation of S/V. RESULTS: Among all groups, there was a significant reduction in NT-proBNP level (Group 1: p < .01, Group 2: p < .01, and Group 3: p < .001). In addition, there was a significant reduction in diuretic dose across all groups combined (furosemide 53 mg/day vs. 73 mg/day; p = .03), with 17.8% (8/45) patients being able to discontinue their diuretic completely. There was no significant change in potassium or creatinine. CONCLUSIONS: Lower than standard dose of S/V significantly reduces NT-proBNP and diuretic requirement without change in potassium or creatinine, which provides hope that patients who cannot tolerate standard doses of S/V due to hypotension may be able to receive the benefits of S/V therapy.

BACKGROUND The aim of this study was to further clarify the effects of valsartan on restenosis in patients with arteriosclerosis obliterans of the lower extremities. MATERIAL AND METHODS Patients with arteriosclerosis obliterans of the lower extremities undergoing continuous stent implantation in the superficial femoral artery were enrolled and randomly divided into an ARB group and a control group. Patients in the ARB group received valsartan orally in a single-blind manner and were followed up for 6 months. An evaluation was performed based on the criteria for clinical efficacies designed by the Committee of Vascular Disease, Chinese Association of Integrative Medicine. The total clinical effective rate was calculated, and ankle brachial index (ABI) of the patients was assessed. The concentrations of interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) were measured using enzyme-linked immunosorbent assay. The in-stent restenosis of patients was examined by angiography. RESULTS One patient in the control group died due to acute cerebral hemorrhage 4 months after enrollment, and 1 patient was lost to follow-up due to acute myocardial infarction during follow-up 5 months after enrollment. Age, sex, Fontaine stage, and underlying diseases were comparable between the 2 groups. Hs-CRP (3.93±1.43) and IL-6 (11.26±2.29) levels were significant different in the ARB group compared with the control group. The postoperative follow-up showed that ABI was 0.98±0.20 in the ARB group and 0.62±0.48 in the control group. CONCLUSIONS Valsartan inhibited the increase in hs-CRP and IL-6 levels, improved clinical efficacies, increased ABI, and decreased the restenosis rate after the interventional therapy in patients with arteriosclerosis obliterans of the lower extremities.

BACKGROUND/PURPOSE: The aim of this study was to evaluate the efficacy and safety of Tripterygium Wilfordii Hook F (TWHF) in DN patients with overt proteinuria and normal eGFR. METHODS: 124 eligible DN patients were randomly assigned into two groups to receive either valsartan 160 mg/d treatment (control group) or TWHF 60 mg/d plus valsartan 160 mg/d treatments (TWHF group) for 24 weeks. The changes of clinical, biochemical data and adverse events during observation period were all analyzed. The primary endpoint was a reduction in 24-h urine protein excretion between baseline and the end of study, the secondary endpoint was to observe the change in estimated glomerular filtration rate (eGFR) between two groups. RESULTS: After treatment, there was a more significant decrease in proteinuria in patients who received TWHF treatment (from 4.95 ± 1.27 g/24 h to 3.36 ± 0.83 g/24 h) compared to valsartan monotherapy (from 5.21 ± 1.59 g/24 h to 4.52 ± 1.06 g/24 h). The percentage change in urine protein excretion was -32.12% in TWHF group and -13.24% in valsartan group. Patients' plasma albumin in TWHF group (from 32.53 ± 5.24 g/L to 36.91 ± 4.42 g/L) was higher than that in control group (from 33.18 ± 4.87 g/L to 34.67 ± 4.75 g/L). No significant change in blood pressure, blood glucose, eGFR, and serum potassium was observed. But the adverse events in TWHF group were higher than those in control group. CONCLUSION: TWHF is more effective than valsartan monotherapy in reduction of proteinuria in DN patients with overt proteinuria and normal eGFR, but with more adverse effects.

Background: Numerous clinical studies have evaluated valsartan and found more efficacious control of blood pressure (BP) variability when administered before sleep. The treatment leads to improved outcomes when compared to administration upon awakening. The mechanism underlying this etiology is not fully understood. The present study investigates the safety and efficacy of asleep administration of valsartan in spontaneously hypertensive rats (SHR) with a non-dipping blood pressure pattern compared to SHRs receiving administration during awake time. Materials and Methods: 84 Male SHRs and 28 male Wistar-Kyoto rats (WKY) were kept under a strict alternating 12-h light/dark cycle. WKYs were utilized as a non-disease control. Meanwhile, SHRs were randomly divided into three groups: untreated, Valsartan asleep administration (VSA) and Valsartan awake administration (VWA) respectively. The VSA group was treated with valsartan (30 mg/kg/d) after the light onset, while the VWA group was treated with valsartan (30 mg/kg/d) after light offset. Both groups were treated for 6 weeks. Tail artery blood pressure was measured every 4 h via a noninvasive tail cuff blood pressure measurement method. HE and Masson staining were used to evaluate any damage within the target organs. ELISA was used to determine the 24-h plasma renin-angiotensin system (RAS) concentration at 4-h intervals. Results: Based on our findings, VSA significantly reduced 24-h and evening mean BP and restored the abnormal circadian rhythm compared to VWA, which attenuated injuries in the majority of target organs except for the kidneys. Furthermore, VSA was found to activate RAS during the light cycle and inhibit it during the dark cycle. Conversely, VWA was found to deactivate RAS throughout the day which may be related to the circadian BP rhythm. Conclusion: VSA may be more efficacious than VWA in controlling BP, circadian BP rhythm and blood RAS rhythm. Recent cardiovascular outcome investigations substantiate that chronotherapy treatment might be a novel therapeutic strategy for hypertension therapy.
