肝硬化失代偿期患者心功能改变32例分析

Study of the changes of cardiac function in liver cirrhosis with ultrsound

目的:探讨肝硬化失代偿期患者心功能的改变。方法:采用2.5MHz探头测量32例肝硬化失代偿期患者(肝硬化组)和35例正常人(对照组)心功能各项指标。测量分别取左室长轴切面,心尖四腔心切面,主动脉短轴切面。结果:肝硬化组舒张功能中的二尖瓣舒张早期峰值速度(EV)及EV与二尖瓣舒张晚期峰值速度(AV)的比值(EV/AV)明显低于对照组(P<0.01);三尖瓣舒张早期峰值速度(TEV)也明显低于对照组(P<0.01);三尖瓣舒张晚期峰值速度(TAV)明显增加(P<0.01);TEV/TAV明显降低(P<0.01);右心功能中肺动脉瓣加速时间(ACT)明显缩短(P<0.01)。结论:肝硬化失代偿期左心舒张功能受累,右心收缩和舒张功能均受累。

Objective： To observe the changes of cardiac function in liver cirrhosis decompensation stage. Methods： This article reports the cardiac function changes of 32 cases liver cirrhosis patients in decomepensation stage as compared with 35 health persons. Some heat parameters are measured. Results： In liver cirrhosis decompensation stage the EV of mitral vale and EV/AC in diastole function decreased significantly, the TEV of tricuspid valve decreased （P〈 0.01 ）, the TAV of tricuspid vale increased （P 〈 0.01）, TEV/TAVdecreased markedly（P〈0.01）,In right cardiac function ACT shortened（P〈0.01）. Conclusion： In the decomepensation stage of patients with liver cirrhosis,the left ventricular diastole function is affected, the right ventrieular systole and diastole functions are affected greatly.
