Tei指数评估妊娠期糖尿病胎儿及其出生后整体心功能的价值

【】目的 探讨Tei指数评估妊娠期糖尿病(GDM)胎儿及其出生后整体心功能的价值。 方法 选取2015年1月-2016年6月我院收治的47例GDM血糖控制不良孕妇(A组)、55例GDM血糖控制良好孕妇(B组)、70例正常妊娠产妇(C组)作为研究对象,所有孕妇均为单胎妊娠。在入组时、分娩后1-7d、分娩后2-3月,采用多普勒超声心动图检测胎儿的左心室及右心室Tei指数。 结果 入组时、分娩后1-7d、分娩后2-3月,3组胎儿左心室Tei指数、右心室Tei指数相比差异均有统计学意义(P＜0.05)。同一个时间点组间进行比较：A组胎儿左心室Tei指数、右心室Tei指数均显著高于B组、C组胎儿(P＜0.05),B组、C组胎儿之间左心室Tei指数、右心室Tei指数相比差异无统计学意义(P＜0.05)。 结论 积极有效控制血糖可以避免GDM胎儿的心功能受损。血糖控制不良可以损害GDM胎儿心功能,即使胎儿分娩后2-3个月内其心功能仍然处于异常水平。

Evaluation of fetal cardiac function and fetal cardiac function in gestational diabetes mellitus by Tei index Value

Objective To investigate the value of Tei index in evaluating the fetal cardiac function in gestational diabetes mellitus (GDM). Methods from January 2015 -2016 June in our hospital 47 cases of GDM in pregnant women with poor glycemic control (A group), 55 cases of GDM with good glycemic control in pregnant women (B group) and 70 cases of normal pregnant women (C group) as the research object, all pregnant women were singleton pregnancies. The left ventricular and right ventricular Tei index was measured by Doppler echocardiography at the time of delivery, 1-7d after delivery and 2-3 months after delivery. Results there were significant differences in left ventricular Tei index and right ventricular Tei index between the 3 groups (P < 0.05) after delivery, 1-7d after delivery and 2-3 months after delivery. Compare the same time between the two groups: A group fetal Tei index of left ventricular and right ventricular Tei index were significantly higher than that of B group, C group of fetus (P < 0.05), no statistical significance between the B group and C group of fetal left ventricular Tei index, Tei index difference (P < 0.05). Conclusion active and effective control of blood glucose can avoid the damage of cardiac function in GDM fetus. Poor glycemic control can damage the heart function of GDM fetal cardiac function, even within 2-3 months after the fetal abnormal level is still in.
