Role of recombinant human brain natriuretic peptide combined with sodium nitroprusside in improving quality of life and cardiac function in patients with acute heart failure

The present study aimed to investigate the role of recombinant human brain natriuretic peptide (RHBNP) combined with sodium nitroprusside (SN) in improving quality of life and cardiac function in patients with acute heart failure. A total of 96 patients with acute heart failure who were admitted to The First Affiliated Hospital of Yangtze University were included in the current study. A total of 48 patients were treated with RHBNP combined with SN (research group) and 48 patients were treated with SN alone (control group). To assess the efficacy and safety of the two treatments, the study groups were compared in terms of improvement in clinical symptoms and cardiac function indices, including pulmonary capillary wedge pressure and left ventricular ejection fraction, which was measured using a non-invasive cardiac hemodynamic detector; changes in fluid intake and 24 h urine volumes after drug use; cardiac function classification before treatment and three days after treatment; adverse drug reactions during treatment and mortality within 1 month of treatment. Following treatment, compared with the control group, the research group demonstrated significantly higher fluid intake and 24 h urine volume after drug use, improved cardiac function indices, cardiac function classification, biochemical indicators and total effective rate of treatment (all P<0.05); significantly lower total incidence of adverse reactions (P<0.05) and similar mortality within 1 month of treatment. With improvements in cardiac and other organ function, RHBNP combined with SN was found to be effective in the treatment of acute heart failure. RHBNP can effectively promote urination, reduce inflammatory responses and rapidly relieve clinical symptoms without significant adverse reactions, indicating its potential use in further clinical application.
