RESUMO
OBJECTIVE:To observe clinical efficacy and safety of rhBNP combined with levosimendan in the treatment of acute heart failure,and to investigated the effects of drug combination on serum UA and BNP levels. METHODS:68 patients with acute heart failure were randomly divided into observation group and control group,with 34 cases in each group. Both groups re-ceived routine treatment;control group was additionally given Levosimendan injection 5 ml added into 0.9% Sodium chloride in-jection 45 ml with persistent micropump injection:at pump rate of 12 μg/(kg·min)within first 1 h,and then at pump rate of 0.5μg/(kg·min)for consecutive 23 h;observation group was additionally given rhBNP 1.5 μg/kg for intravenous shock,and then giv-en consecutive intravenous injection of rhBNP at rate of 7.5 ng/(kg·min)continuous 3-7 days on the basis of control group. Clini-cal efficacy of 2 groups were observed,and serum levels of UA and BNP,heart function index,the safety of drug use were ob-served before and after treatment. RESULTS:After treatment,total effective rate of observation group(94.11%)was significantly higher than that of control group (70.59%),with statistical significance (P0.05). CONCLUSIONS:rhBNP combined with levosimendan have significant clinical efficacy and high safety in the treatment of acute heart failure.
