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 re-ductions 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.
