Abstract:
Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.
