Abstract
AIM: To investigate the effects of recombinant human brain natriuretic peptide (rhBNP) on efficacy, hemodynamics, and N-terminal pro-brain natriuretic peptide (NT-proBNP) in elderly patients with heart failure (HF). METHODS: In this retrospective analysis, the clinical data of 112 HF patients who visited the First Affiliated Hospital of Anhui University of Chinese Medicine between March 2019 and October 2022 were analyzed. On the basis of standard HF treatment, 52 patients additionally treated with milrinone intravenous were set as the control group (Con) and 60 patients with rhBNP were set as the observation group (Obs). The therapeutic efficacy and pre- and post-treatment echocardiographic indexes, NT-proBNP and hemodynamics were recorded and compared, and the adverse drug reactions and quality of life scores after treatment were counted. RESULTS: The Obs group showed a markedly higher post-treatment overall response rate than the Con (P=0.002). Besides, more obvious improvement of NT-proBNP and hemodynamic indexes were determined in the Obs group compared to the Con (P=0.000). Evidently ameliorated left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic diameter (LVESD) were observed in both groups after treatment, with more pronounced improvement in the Obs group (all P=0.000). The Obs group also exhibited an evidently lower incidence of adverse reactions and a better quality of life than the Con after treatment (P=0.000). CONCLUSIONS: rhBNP can effectively improve the cardiac function and hemodynamics in elderly HF patients, with high safety and few adverse reactions.
