Clinical effect of recombinant human brain natriuretic peptide in the treatment of heart failure in elderly patients

BackgroundHeart failure in elderly individuals poses significant challenges due to the decline in cardiac function associated with aging. This study aimed to investigate the clinical efficacy of recombinant human brain natriuretic peptide (rhBNP) for the treatment of heart failure, especially in elderly patients. MethodsThis was a retrospective case control study of the medical records of 60 elderly patients with heart failure admitted to our hospital between December 2020 and December 2023. Patients were divided into two groups based on treatment. The control group (n = 30) received diuretics, digitalis, and beta receptor blockers, while the observation group (n = 30) received lyophilized rhBNP in addition to the control group treatment. Changes in BNP levels and clinical outcomes were compared between the two groups. ResultsPosttreatment BNP levels were significantly lower in the observation group than in the control group (p < 0.05), and the total clinical effective rate was greater in the observation group (p < 0.05). Additionally, the left ventricular diameter, left atrial diameter, left ventricular shortening fraction, diastolic flow signal and cardiac output in the observation group were lower than those in the control group (p < 0.05), while the thickness of the aortic root diameter in the observation group was greater than that in the control group (p < 0.05). ConclusionRhBNP demonstrated ideal clinical efficacy in elderly patients with heart failure, improving symptoms and indicating potential for widespread use in the future.
