OBJECTIVES: To demonstrate possible functional changes in the frequently affected fetal interventricular septum (IVS) with spectral tissue Doppler imaging (TDI) and M-mode imaging to compare gestational diabetes mellitus (GDM) and control groups.
METHODS: A total of 63 pregnant women with GDM, 30 on diet (A1 GDM) and 33 on treated with insulin (A2 GDM), and 63 healthy pregnant women randomly selected and matched to the case group in the control group were included.
RESULTS: The GDM fetuses had significantly thickened IVS, increased early diastole (E'), atrial contraction (A'), systole (S'), higher myocardial performance index (MPI'), prolonged isovolumetric relaxation time (IVRT'), shortened ejection time (ET'), and decreased septal annular plane systolic excursion (SAPSE) than the controls. The A2 GDM group fetuses had significantly thickened IVS, increased S' and shortened ET' than the A1 GDM group. In the GDM group, we found a significantly positive low correlation between glycated hemoglobin levels and maternal serum fasting glucose and one-hour postprandial glucose with fetal IVS thickness. We demonstrated a significantly negative low correlation between maternal serum one-hour postprandial glucose, glycated hemoglobin levels, and gestational weight gain with fetal IVS ET'.
CONCLUSIONS: Fetal IVS diastolic and systolic functions were altered in the GDM group compared to controls, and systolic functions were altered in A2 GDM compared to A1 GDM. This may alert clinicians to possible cardiovascular diseases in the postnatal life, and early preventive strategies and long-term lifestyle changes may provide protection in fetuses with GDM.
