肝硬化患者血浆氨基末端B型尿钠肽前体水平变化及其临床意义

目的 观察肝硬化患者血浆氨基末端B型尿钠肽前体(NT-proBNP)水平,并探讨其临床意义.方法 测定60例肝硬化患者和30例健康对照者的血浆NT-pmBNP水平及相关的临床生化参数,对肝硬化患者进行Child-Pugh分级;同时应用彩色多普勒检测心脏的结构和功能.结果肝硬化患者血浆NT-proBNP水平为(38.63±36.05)pmol/L,明显高于健康对照者的(7.50±8.25)pmol/L,P<0.01.不同肝功能分级和腹水量患者血浆NT-proBNP水平差异无统计学意义.肝硬化患者E/A均<1,E峰减速时间(EDT)延长[(189.2±25.0)ms],与健康对照者的(163.3±32.0)ms比较,差异有统计学意义(P<0/05).结论 肝硬化患者心脏舒张功能异常.肝硬化患者血浆NT-proBNP水平升高可能提示早期的心功能损害,其改变与肝功能和腹水无关.

Plasma N-terminal pro-brain natriuretic peptide level and its clinical significance in liver cirrhosis

Objective To detect the levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and investigate its relationship with liver function, ascites and heart structure in patients with liver cirrhosis. Methods The levels of plasma NT-proBNP and various clinical and biochemical parameters were determined in 60 patients with liver cirrhosis and 30 healthy controls. Meanwhile Child-Pugh liver function was classified. All people underwent color Doppler echocardiography. Results The level of plasma NT-proBNP was significantly elevated in patients with liver cirrhosis [(38.63±36.05)pmol/L], compared with that of the controls [(7.50±8.25)pmol/L],P<0.01. There was no significant difference in different Child-Pugh class and aseites amount of liver cirrhosis. E/A < 1 and E wave decelerate time (EDT) was in-creased in liver cirrhosis. Conclusion The levels of plasma NT-proBNP in liver cirrhosis are significantly elevated, and related to early impairment of diastolic function. But it does not correlate with liver function and aseites.
