Key result
The prevalence of fetal myocardial hypertrophy in diabetic pregnant women was 79.3% (115 of 145), and glycemic control had no correlation to its occurrence.
Why the study?
The study was designed to demonstrate the prevalence of fetal myocardial hypertrophy in pregnant women with diabetes mellitus using spatio-temporal image correlation (STIC) M-mode.

What is the prevalence of fetal myocardial hypertrophy in pregnant women with diabetes mellitus when assessed by STIC M-mode ultrasound?
Fetal myocardial hypertrophy is highly prevalent (79.3%) in pregnant women with diabetes mellitus, regardless of glycemic control, when assessed by STIC M-mode ultrasound.
FMH is highly prevalent in diabetic pregnancies independent of glycemic control; leaves open whether routine fetal cardiac surveillance alters outcomes.
Objective: The aim was to demonstrate the prevalence of fetal myocardial hypertrophy (FMH) in diabetes mellitus (DM) pregnant women using spatio-temporal image correlation (STIC) M-mode. Material and Methods: This prospective descriptive study was conducted at Bhumibol Adulyadej Hospital (BAH) Royal Thai Air Force between April and December 2022. Participants were singleton DM pregnant women with gestational age (GA) between 18 and 40 weeks who had antenatal care and delivery at BAH. DM screening was randomized blood sugar obtained from all participants. All participants underwent fetal heart exams by four-dimension ultrasound with STIC M-mode. Results: One hundred and forty-five participants were recruited and classified as pregestational (PDM) and gestational DM (GDM) at 31 and 114 cases, respectively. The mean age of participants was 31.7 years old. Fasting blood sugar (FBS) of PDM was significantly higher than GDM (105.1 vs 87.0 mg%). GDMA2 had more elevated FBS than GDMA1 (p < 0.001). PDM had significantly greater FBS and two-hour postprandial blood sugar (2hr-PP) than GDM (105.1/87.0 and 151.5/117.9 mg%, respectively). FBS and 2hr-PP of GDMA2 were more than GDMA1 with statistical significance. Good glycemic control of GDM was significantly better than PDM. GDMA1 had better glycemic control than GDMA2 with statistical significance. Four-fifth (115/145) of participants had FMH. FMH and estimated fetal weight among PDM and GDM were comparable. Both good and poor glycemic control had similar FMH. Neonatal outcomes of FMH or non-FMH infants were similar. Conclusion: The prevalence of FMH in diabetic pregnant women was 79.3%. Glycemic control had no correlation to FMH.

Sapanont et al. (2023) conducted an observational in Diabetes mellitus in pregnancy (n=145). Diabetes mellitus (pregestational and gestational) was evaluated on Fetal myocardial hypertrophy (FMH). The prevalence of fetal myocardial hypertrophy in diabetic pregnant women was 79.3% (115 of 145), and glycemic control had no correlation to its occurrence.
