脓毒症是由感染引起的全身炎症反应综合征,具有很高的发病率和病死率。脓毒症患者病情进展可导致多器官功能障碍综合征(MODS),其中心肌抑制则是脓毒症重要并发症[1]。有统计数据显示,大约有40%~50%的脓毒症患者存在心功能不全,其中出现心力衰竭者占7%~[2]。血清N端脑钠肽前体(NT-pro BNP)是实时评价心脏功 Sepsis is a systemic inflammatory response syndrome caused by infection with high morbidity and mortality. Progress in sepsis patients can lead to multiple organ dysfunction syndrome (MODS), myocardial infarction is an important complication of sepsis [1]. Statistics show that about 40% to 50% of patients with sepsis have heart failure, including heart failure accounted for 7% ~ [2]. Serum N-terminal pro-brain natriuretic peptide (NT-pro BNP) is a real-time evaluation of cardiac work
