Abstract Objective: To study the effects of recombinant human brain natriuretic peptide (rhBNP) on myocardial enzymes and N-terminal pro-brain natriuretic peptide (NT-proBNP) in elderly patients with acute decompensated heart failure (ADHF). Methods: A total of 150 elderly ADHF patients admitted to our hospital from June 2017 to June 2018 were enrolled in the study. They were divided into control group and study group by simple random number table method, with 75 cases in each group. Control group was treated with conventional methods while study group was treated with rhBNP on the basis of conventional treatment, and they were treated for 1 week. The efficacy, and cardiac function indexes, 24h urine volume, myocardial enzymes, and NT-proBNP before and after treatment were compared between the two groups, and the occurrence of adverse reactions was monitored. Results: The total post-treatment effective rate in study group was higher than that in control group(P<0.05). The post-treatment evaluation reveals the following facts, compared to pre-treatment: the left ventricular ejection fraction (LVEF) in both groups was higher while the left ventricular end-systolic volume (LVESV) and left ventricular end-diastolic volume (LVEDV) were lower, and the LVEF in study group was higher than that in control group while the LVESV and LVEDV were lower than those in control group (P<0.05). The 24h urine volume in both groups was higher and the 24h urine volume in study group was higher than that in control group (P<0.05).The levels of lactate dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme MB (CK-MB) and α-hydroxybutyrate dehydrogenase (α-HBD) in both groups were lower and the above indexes in study group were lower than those in control group (P<0.05). The level of NT-proBNP in both groups was lower and the level of NT-proBNP in study group was lower than that in control group (P<0.05). The incidence rates of adverse reactions in both groups during treatment were 18.67% and 21.33% respectively (P>0.05). Conclusion: RhBNP has significant efficacy in the treatment of elderly patients with acute decompensated heart failure. It helps improve the level of myocardial enzymes, increase urine output and improve cardiac function, and it proves to be highly safe and applicable.
