Abstract
AbstractObjectiveTo determine whether changes in fetal heart function according to glycemic control in pregnant women with Type 1 and Type 2 diabetes using spectral tissue Doppler imaging (TDI) and M‐mode imaging.MethodsThis study included 68 pregestational diabetic women (DM) at 30–32 gestational weeks. All participants were divided into two groups: type 1(n = 17) and type 2(n = 51), and then these groups were divided into the subgroups as well‐controlled and poorly controlled, according to fasting glucose (FG) and 1‐h postprandial glucose (PPG) values. Cardiac parameters were compared for well‐ and poorly‐controlled groups with TDI and M‐mode imaging. The correlation of cardiac parameters with FG, PPG, and HbA1c values was evaluated. Their roles in predicting neonatal outcomes were also assessed.ResultsThickness measurements, early diastolic annular peak velocity (E’), late diastolic annular peak velocity (A’), tissue isovolumetric relaxation time (IRT’), and tissue myocardial performance index (MPI’) were increased in both poorly controlled groups. Tissue ejection time (ET') was significantly reduced in the poorly controlled groups, while tissue isovolumetric contraction time (ICT') was not significantly changed in any group. Tricuspid, mitral, and septal annular plane excursions (TAPSE, MAPSE, and SAPSE, respectively) were significantly decreased in all poorly controlled subgroups. E', E'/A’, MPI’, IRT', ET', and M‐mode imaging parameters significantly correlated with FG notably.ConclusionMaternal hyperglycemia leads to subtle changes in systolic and diastolic functions both in the interventricular septum and ventricles, so it is essential to ensure glycemic control in both Type 1 and Type 2 DM.
