慢性肾衰竭患者左室Tei指数与左室心肌质量的相关性分析

摘要

Objective: To investigate the correlation of left ventricular Tei index with left ventricular mass(LVM) in patients with chronic renal failure. Methods:Forty patients confirmed as chronic renal failure between 2013 and 2014 were included,and another 40 without renal failure were recruited as control subjects.Pulsed Doppler echocardiography(PDE) was used to measure the left ventricular Tei index,LVM and LVM index,and the results were an-alyzed.Results:Higher left ventricular Tei index was seen in patients with chronic renal failure (t=16.62,P<0.01),and the elevated Tei index was pos-itively correlated with LVM and LVM index ,particularly in strong close to LVM index .Conclusion:The findings suggest that left ventricular Tei index can serve as a modality to evaluate the left ventricular condition for patients with chronic renal failure .%目的：探讨慢性肾衰竭患者左室Tei指数与左室心肌质量（ LVM）的相关性。方法：收集2013～2014年我院临床确诊为慢性肾衰竭患者40例作为观察组，无慢性肾衰竭患者40例作为对照组。用多普勒超声诊断仪分别获得观察组和对照组的左室Tei指数、LVM及左室心肌质量指数（ LVMI），并进行相关性分析。结果：慢性肾衰竭患者的Tei指数明显高于正常对照组（t＝16．62，P＜0．01）。慢性肾衰竭患者Tei指数的升高与LVM及LVMI的增加均呈正相关且与LVMI关系更为密切。结论：左室Tei指数与LVM呈正相关性，与LVMI的关系相较LVM更为密切，左室Tei指数可综合反映慢性肾衰竭患者的左室功能状态。 Tei指数测量操作较简便，值得推广应用。
