Lyophilized recombinant human brain natriuretic peptide for chronic heart failure:Effects on cardiac function and inflammation

BACKGROUND Chronic heart failure(CHF)is a serious and prevalent condition characterized by impaired cardiac function and inflammation.Standard therapy for CHF has limitations,prompting the exploration of alternative treatments.Recombinant human brain natriuretic peptide(BNP)has emerged as a potential therapy,with evidence suggesting that it can improve cardiac function and reduce inflammation in patients with CHF.However,further research is required to determine the efficacy and safety of lyophilized recombinant human BNP in CHF patients and its impact on microinflammatory status.This study aimed to investigate the effects of lyophilized recombinant human BNP therapy on CHF patients’cardiac function and microinflammatory status.AIM To investigate the effects of freeze-dried recombinant human BNP therapy on cardiac function and microinflammatory status in patients with CHF.METHODS In total,102 CHF patients admitted to our hospital from January 2021 to January 2022 were randomly assigned to control and observation groups(n=51 patients/group).The control patients were treated with standard HF therapy for 3 d,whereas the observational patients were injected with the recombinant human BNP for 3 d.Clinical efficacy,inflammatory factor levels,myocardial damage,cardiac function before and after the treatment,and adverse reactions during treatment were compared between the two groups.RESULTS The overall clinical efficacy was higher in the observation group than in the control group.Compared with baseline,serum hypersensitive C-reactive protein,N-terminal proBNP,and troponin I level,and physical,emotional,social,and economic scores were lower in both groups after treatment,with greater reductions in levels and scores noted in the observation group than in the control group.The overall incidence of adverse reactions in the observation group was not significantly different compared with that in the control group(P>0.05).CONCLUSION Freeze-dried recombinant human BNP therapy can improve heart function and enhance microinflammatory status,thereby improving overall quality of life without any obvious side effects.This therapy is safe and reliable.

Lyophilized recombinant human brain natriuretic peptide: A promising therapy in patients with chronic heart failure

Lyophilized recombinant brain natriuretic peptide(BNP)is an exogenous peptide synthesized by artificial recombination technology,with a similar structure and similar physiological effects with the endogenous natriuretic peptide secreted by the human body.It’s main mechanism of action is to increase cyclic guanosine monophosphate by binding with its corresponding receptor in the body,regulating,thus,the imbalance of the vascular system and cardiac hemodynamics,improving the heart’s pumping capacity,and inhibiting sympathetic excitability and myocardial remodeling.Moreover,it can promote mitochondrial metabolism and enhance the use of adenosine triphosphate in cardiomyocytes.In the present study,102 chronic heart failure(HF)patients were randomly assigned to a control and an observation group consisting of 51 patients each.Patients of the control group were treated with standard HF therapy for 3 d including oral metoprolol tartrate tablets,spironolactone,and olmesartanate while patients of the observation group were administered the recombinant human BNP injection for the same time-period,plus the standard HF therapy.The recombinant human BNP group(observation group)demonstrated better physical,emotional,social,and economic scores,as well as cardiac and inflammatory biomarkers such as serum hypersensitive C-reactive protein,N-terminal pro BNP and troponin I levels,compared to the control group.Moreover,cardiac function was also improved,as left ventricular ejection fraction and stroke volume were significantly higher in the observation group than in the control group.Interestingly,adverse reactions were not different between the 2 groups.However,these results are not generalizable and the need of large multicenter randomized controlled trials examining the safety and efficacy of recombinant human BNP in HF patients is of major importance.

Effect Study of the Recombinant Human Brain Natriuretic Peptide in Patients with Heart Failure Combined with Hypotension

Objective: This paper aims to investigate the effect of applying recombinant human brain natriuretic peptide in patients with heart failure combined with hypotension. Recombinant human brain natriuretic peptide is a synthetic polypeptide drug that is primarily used to treat acute heart failure. Its mechanism of action closely mimics that of human endogenous brain natriuretic peptide. By binding to receptors on cardiomyocytes, it exerts its pharmacological effects. Methods: For the study, 76 heart failure patients with hypotension were selected from our hospital between May 2022 and June 2023. These patients were divided into two groups: a control group and an observation group, each comprising 38 patients. The control group received dopamine treatment, while the observation group was treated with recombinant brain natriuretic peptide. The objective was to compare the effects of the treatments in both groups by analyzing cardiac function indices and levels of vasoactive substances to identify any significant differences in outcomes. Results: The overall response rate of the patients in the observation group and the control group was 94.74% and 73.68%, significantly higher as compared with the observation group (P 0.05). After the following treatment, BNP, ANNP and urine output in the observation group were significantly different compared with the control group, of the statistical significance (P Conclusion: For the treatment of heart failure patients with hypotension, the clinical application of recombinant human brain natriuretic peptide is the most ideal, and significantly improves the cardiac function of patients, which is worth popularizing.

Differential effects of atrial and brain natriuretic peptides on human pulmonary artery:An in vitro study

BACKGROUND The prevalence of cardiovascular diseases,especially heart failure,continues to rise worldwide.In heart failure,increasing levels of circulating atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP)are associated with a worsening of heart failure and a poor prognosis.AIM To test whether a high concentration of BNP would inhibit relaxation to ANP.METHODS Pulmonary arteries were dissected from disease-free areas of lung resection,as well as pulmonary artery rings of internal diameter 2.5–3.5 mm and 2 mm long,were prepared.Pulmonary artery rings were mounted in a multiwire myograph,and a basal tension of 1.61gf was applied.After equilibration for 60 min,rings were pre-constricted with 11.21μmol/L PGF2α(EC80),and concentration response curves were constructed to vasodilators by cumulative addition to the myograph chambers.RESULTS Although both ANP and BNP were found to vasodilate the pulmonary vessels,ANP is more potent than BNP.pEC50 of ANP and BNP were 8.96±0.21 and 7.54±0.18,respectively,and the maximum efficacy(Emax)for ANP and BNP was-2.03 gf and-0.24 gf,respectively.After addition of BNP,the Emax of ANP reduced from-0.96gf to-0.675gf(P=0.28).CONCLUSION BNP could be acting as a partial agonist in small human pulmonary arteries,and inhibits relaxation to ANP.Elevated levels of circulating BNP could be responsible for the worsening of decompensated heart failure.This finding could also explain the disappointing results seen in clinical trials of ANP and BNP analogues for the treatment of heart failure.
