Brief summary
To compare the therapeutic efficacy of recombinant human brain natriuretic peptide (rhBNP) with dobutamine on acute decompensated heart failure patients with different blood BNP levels
Detailed description
Patients with acute decompensated heart failure (ADHF) whose left ventricular ejection fraction(LVEF) was \<40%, were assigned to a high BNP group (BNP ≤ 3000 pg/mL) or an extra-high BNP group (BNP \> 3000 pg/mL) , depending on their admission plasma BNP levels. Each group was then subdivided into rhBNP or dobutamine subgroups according to intravenous administration with either rhBNP or dobutamine for 24-72h. The effects of rhBNP and dobutamine on patients in the high and extra-high BNP groups were compared.
