Abstract：Objective To evaluate the value of two-dimensional speckle tracking imaging (STI) in evaluating the cardiac function of pregnant women with different pregnancy induced hypertension.Methods From Jan 2014 to Jan 2015 in Tangshan Union Hospital,selected pregnant women with pregnancy induced hypertension (PIH, n =48 ) , normal pregnant women(n =45), healthy nonpregnant women(n =45).STI software were used for image analysis, recorded the three groups of integral torsion angle peak (Ptw) , heart horizontal angle of rotation (prot-MV) , heart horizontal rotation angle of the peak time (Pti-MV) , peak time percentage (perc-Pti-MV) , apical horizontal rotation angle peak (Prot-AP) , apical level reached the peak time (Pti-AP) and peak time percentage (Perc-Pti-AP) .Results Pti-MV in PIH group and normal pregnancy group in early and middle pregnancy were lower than the control group (t =8.963, t =9.142, P <0.05), and PIH group in late pregnancy was higher than the normal pregnancy group in late pregnancy (t =10.236, P <0.05);Prot-AP, Perc-Pti-MV, Perc-Pti-AP,Ptw were higher in PIH group and normal pregnancy group trimester level than the control group (t Prot-AP =7.855,8.023,9.141,10.022;t Perc-Pti-MV =8.002,10.963,9.445,9.856;t Perc-Pti-AP =11.263,8.022,9.102,8.012;t Ptw =10.232,11.011,9.126,11.452, P <0.05), the Prot-AP in PIH group from early pregnancy to the advanced pregnancy were higher than those in normal pregnancy group during the same period (P <0.05), Perc-Pti-MV in PIH in the middle and late pregnancy group and normal pregnancy group’s late pregnancywere higher than the level of the early pregnancy (P <0.05), Ptw in advanced level of PIH group was higher than that of the late pregnancy in pregnancy group (P <0.05), and higher than the PIH group’s early pregnancy (P <0.05).Ptw were positive correlated with BSA, Pro-AP(r =0.295,0.342, P <0 .05),and with no correlation with maternal height, LVEDV, LVEF, Pro-MV (P >0.05).Conclusion By early applica-tion of STI technology, the left ventricular rotation and torsion motion of PIH patients can be observed, which is helpful for the evaluation of early cardiac function in patients with PIH.
