Effects of rhBNP on Elderly Emergency Patients with Acute Heart Failure

Wang J, Li Y, Guo J, Nie S

Objective: To study the effect of re-combinant human brain natriuretic peptide (rhBNP) in older emergency patients with acute heart failure.
Patients and Methods: A total of 130 patients were randomly divided into two groups as: rhBNP treatment group and sodium nitroprusside (SNP) treatment group, half by half. The rhBNP was taken once every three days for treatment. But dose was doubled at first time used. In the whole progress, it measured the concentration of rhBNP. Echocardiography examination and 6-minute walk testing (6MWT) were used to evaluate the improvement of heart function after rhBNP treatment, compared with SNP.
Results: It taken vital symptoms assessment according to the clinical manifestations, once every four hours in the whole 48 hours emergency treatment procedure. Compared before and after treatment, there were significant improvement about LVEF (left ventricular ejection fraction), 6MWT and proBNP level changes in rhBNP group. Furthermore, it revealed that there were also significant differences in LVEF, 6MWT and proBNP level changes between rhBNP and SNP group.
Conclusion: Recombinant human brain natriuretic peptide (rhBNP) could be used to treat old patients with acute heart failure in emergency with meaningful clinical value.
