Clinical efficacy of rhBNP in treating AHF and its effect on hemodynamics and inflammatory factors / 重庆医学

ABSTRACT

Objective To explore the clinical efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the treatment of acute heart failure(AHF) by observing the changes of hemodynamic parameters,cardiac function and inflammatory factors before and after treatment in the patients with AHF.Methods A total of 96 patients with AHF in our hospital from June 2012 to December 2015 were enrolled in this study and divided into the control group and observation group(n-48).The two groups were given the routine anti-heart failure treatment combined with sodium nitroprusside or rhBNP by intravenous dripping for 24 h.Fifteen cases were selected from each group for monitoring the hemodynamic change.The clinical effect was observed.The changes of heart rare,blood pressure,urine volume,cardiac function,plasma of NT-proBNP,IL-6 and hs-CRP before and after medication were observed.The occurrence of adverse reactions was also observed.Results The total effective rate of the observation group was significantly higher than that in the control group (P＜0.05).The PAP and PCWP at various time points after treatment in the observation group were significantly lower than those before treatment (P＜0.05).PAP and PCWP at various time points had statistical difference between two groups (P＜0.05).The levels of heart rate,systolic blood pressure,NT-proBNP,IL-6 and hsCRP levels after medication were significantly decreased in both groups,and the urine volume and LVEF were significantly increased (P＜0.05),and the difference between the two groups was statistically significant(P＜0.05).There was no statistically significant difference in the occurrence of adverse reactions between the two groups (P＞0.05).Conclusion The short-term efficacy of rhBNP in treating AHF is better than sodium nitroprusside,which can improve hemodynamics and cardiac function,reduces the level of inflammatory factors.
