Abstract
BACKGROUND: We aimed to evaluate the fetal cardiac functions with Myocardial Performance Index (MPI) in gesta-tional diabetes mellitus (GDM). METHODS: In this study, 35 patients who were diagnosed with GDM, and 35 pregnant without glucose intolerance and their babies were evaluated. Fetal echocardiographic, biometric measurements, umbilical artery pulsatility indices (UAPI) and ductus venosus pulsatility indices (DVPI) measurements were performed to evaluate fetal well-being be-tween the groups. RESULTS: There was no statistically significant difference between the groups in terms of UAPI, DVPI, systolic func-tions, the mode of delivery and 5-minute APGAR scores (P=0.849, P=0.485, P=0.770, P=0.060, P=0.587). There was statistically significant difference between the isovolumetric relaxation time and isovolumetric contraction time of groups (P=0.006, P=0.03). The MPI results were statistically different between the groups (P=0.000). Postpartum need for hos-pitalization was more frequently observed in GDM than the control group (P=0.014). CONCLUSIONS: MPI, which is independent of the ventricular anatomy and fetal heart rate, showing both diastolic and systolic functions, was found significantly higher in GDM. We recommend performing MPI measurement routinely to fetal cardiac functions in GDM.
