Predicting adverse perinatal outcomes with fetal modified myocardial performance index and epicardial fat tissue thickness in diabetes-complicated pregnancies

OBJECTIVE: The aim of this study was to evaluate fetal modified myocardial performance index (mod-MPI) and fetal epicardial fat tissue (EFT) thickness and its association with adverse perinatal outcomes in diabetic pregnant women.PATIENTS AND METHODS: This was a prospective case-control study including 90 gestational diabetes mellitus (GDM) and 45 pregestational diabetes mellitus (PGDM) and 90 healthy pregnant women (control group). Two-dimensional gray-scale and Doppler fetal echocardiography were used to calculate the mod-MPI. EFT thickness was measured in the hypoecho-genic area between the myocardium and the visceral pericardium on the right ventricle by distinguishing it from the pericardial fluid by Doppler ultrasound. RESULTS: Both mod-MPI values and EFT thickness were significantly higher in diabetic pregnant women (p<0.001; for both). No significant differences were observed in mod-MPI values and EFT thickness between pregnant women with GDM and PGDM. In addition, there was no significant difference in fetal mod-MPI values and EFT thicknesses among diabetic pregnant women based on their treatment requirements. The receiver operating characteristic (ROC) curve revealed that mod-MPI value (cut-off 0.54, 95% CI: 0.629-0.837, p
