Abstract To evaluate left ventricular function in newborn infants of mothers with gestational diabetes mellitus (GDM). METHODS: Forty newborn infants of mother with GDM (GDM group) and forty normal newborn infants (control group) were enrolled in this study. Two-dimensional speckle tracking imaging was used to measure interventricular septal thickness, posterior left ventricular wall thickness and left ventricular ejection fraction in both groups. Left ventricular rotation and torsion were evaluated for all participants. RESULTS: Interventricular septal thickness in the GDM group was much higher than in the control group (0.45±0.06 mm vs 0.34±0.05 mm; P0.05). Peak subendocardial rotation, peak subepicardial rotation, peak bulk rotation and peak mural torsion were higher in the GDM group than in the control group (P<0.05). CONCLUSIONS: Cardiac function may be impaired in newborn infants of mothers with GDM, with changes in left ventricular shape and abnormalities of left ventricular rotation and torsion. However, infants have a normal ventricular blood ejection under the cardiac compensation. Two-dimensional speckle tracking imaging technique can be used for early detection of left ventricular function.
