Clinical Efficacy and Safety Analysis of Recombinant Human Brain Natriuretic Peptide Combined with Sacubitril/Valsartan in the Sequential Treatment of Senile Patients with Acute Heart Failure

This study aims to evaluate the comparative efficacy and safety of the combination of recombinant human brain natriuretic peptide (rhBNP) and sacubitril/valsartan in the sequential treatment of senile patients with acute heart failure (AHF).The study objects were a total of 136 senile patients over 60 years old with AHF admitted to the Department of Cardiology of Anji County People's Hospital of Huzhou from August 2022 to August 2023. Using the envelope method, the patients were divided into three groups: the standard treatment group (45 patients who underwent hydragogue, digoxin, valsartan, and beta-blockers), the rhBNP group (46 patients were performed with basic treatment for AHF combined with rhBNP), and the sequential treatment group (45 patients received the basic treatment for AHF combined with rhBNP followed by sacubitril/valsartan). The clinical effects, cardiac function, safety, and prognosis among the three groups were compared.In the sequential treatment group, the duration of clinical symptom remission, the duration of hospitalization, and the improvement rate of New York Heart Association classification at discharge were (2.27 ± 0.76) days, (6.99 ± 1.96) days, and 93.3%, which were better than those in the rhBNP group ([2.58 ± 0.94] days, [7.43 ± 2.78] days, and 78.3%) and the standard treatment group ([2.89 ± 0.71] days, [8.82 ± 2.89] days, and 71.1%); the P value among all groups was lower than 0.05. In terms of cardiac function and myocardial injury, the sequential treatment group was superior to the standard treatment group and rhBNP group. The incidence of adverse reactions in the standard treatment group, the rhBNP group, and the sequential treatment group was 37.8%, 34.8%, and 26.7%, respectively, P = 0.510. In the sequential treatment group, the rate of heart failure readmitted within 6 months after discharge was 28.9% and no death occurred, which was lower than those in the rhBNP (34.8%) and the standard treatment group (35.6%).Sequential treatment with rhBNP and sacubitril/valsartan could significantly improve the clinical symptoms of elderly patients with AHF, enhance cardiac function, and reduce myocardial damage, which could also improve the prognosis.
