ABSTRACT
Context Because acute decompensated heart failure causes substantial morbidity and mortality, there is a need for agents that at least improve hemodynamics and relieve symptoms without adversely affecting survival.
Objective To assess the effect of a short-term intravenous infusion of levosimendan or dobutamine on long-term survival.
Design, Setting, and Patients The Survival of Patients With Acute Heart Failure in Need of Intravenous Inotropic Support (SURVIVE) study was a randomized, double-blind trial comparing the efficacy and safety of intravenous levosimendan or dobutamine in 1327 patients hospitalized with acute decompensated heart failure who required inotropic support. The trial was conducted at 75 centers in 9 countries and patients were randomized between March 2003 and December 2004.
Interventions Intravenous levosimendan (n = 664) or intravenous dobutamine (n = 663).
Main Outcome Measure All-cause mortality at 180 days.
Results All-cause mortality at 180 days occurred in 173 (26%) patients in the levosimendan group and 185 (28%) patients in the dobutamine group (hazard ratio, 0.91; 95% confidence interval, 0.74-1.13; P = .40). The levosimendan group had greater decreases in B-type natriuretic peptide level at 24 hours that persisted through 5 days compared with the dobutamine group (P<.001 for all time points). There were no statistical differences between treatment groups for the other secondary end points (all-cause mortality at 31 days, number of days alive and out of the hospital, patient global assessment, patient assessment of dyspnea at 24 hours, and cardiovascular mortality at 180 days). There was a higher incidence of cardiac failure in the dobutamine group. There were higher incidences of atrial fibrillation, hypokalemia, and headache in the levosimendan group.
Conclusion Despite an initial reduction in plasma B-type natriuretic peptide level in patients in the levosimendan group compared with patients in the dobutamine group, levosimendan did not significantly reduce all-cause mortality at 180 days or affect any secondary clinical outcomes. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领 RESOURCE: Vol. 297 No. 17, May 2, 2007 JAMA ( 2007;297:1883-1891. )

ABSTRACT
Context Because acute decompensated heart failure causes substantial morbidity and mortality, there is a need for agents that at least improve hemodynamics and relieve symptoms without adversely affecting survival.
背景：由于急性失代偿性心衰能导致实际发病率和病死率上升，这就要求药物不仅能改善血液流变学和减轻症状，而且不会相反地影响生存率。
Objective To assess the effect of a short-term intravenous infusion of levosimendan or dobutamine on long-term survival.
目的：获得短期静脉注射左西孟旦或多巴酚丁胺对长期生存率的影响的数据。
Design, Setting, and Patients The Survival of Patients With Acute Heart Failure in Need of Intravenous Inotropic Support (SURVIVE) study was a randomized, double-blind trial comparing the efficacy and safety of intravenous levosimendan or dobutamine in 1327 patients hospitalized with acute decompensated heart failure who required inotropic support. The trial was conducted at 75 centers in 9 countries and patients were randomized between March 2003 and December 2004.
设计，设定和病人：将患有急性心衰并需要静脉收缩药物支持的病人随机分组，双盲实验条件下比较1327名患有急性失代偿性心衰并需要收缩药物支持的病人在静脉注射左西孟旦或多巴酚丁胺后的效力和安全性。这个实验在9个国家的75个中心进行，病人从2003年3月到2004年12月之间的病人中随机抽取。
Interventions Intravenous levosimendan (n = 664) or intravenous dobutamine (n = 663).
干预：静脉注射左西孟旦（n=664），静脉注射多巴酚丁胺（n=663）。
