Objective:To explore the application value of Tei index in determination of fetal cardiac function in pregnant women with gestational diabetes mellitus (GDM).Methods: A total of 60 gestational diabetes mellitus pregnant women with single birth were included in the study and served as GDM group, while 60 healthy pregnant women with single birth were served as the control group. The fetal echocardiography was performed. The cardiac structure, function, and other related indicators were detected and compared.Results:IVSs, LVWT, RVWT, LVEF, LVFS, and RVFS in GDM group were significantly greater than those in the control group (P<0.05). E/A MV and E/A TV in GDM group were significantly lower than those in the control group (P<0.05). The left and right ventricular Tei index in GDM group was significantly higher than that in the control group (P<0.05).Conclusions:The fetal cardiac structure and function in GDM pregnant women can cause damage to a different degree. Tei index is an important indicator to evaluate the fetal cardiac function in GDM pregnant women, and can be applied in the early diagnosis and treatment; therefore, it deserved to be widely recommended in the clinic.
