Neonatal Myocardial Infarction in Association With Gestational Diabetes.

Fetal and neonatal hypertrophic cardiomyopathy is a complication of gestational diabetes and usually follows a benign course. In this report, we present a rare case of a newborn of a diabetic mother with severe ventricular hypertrophy who developed myocardial infarction confirmed by elevated cardiac enzymes, electrocardiographic changes, and subendocardial ischemia on cardiac magnetic resonance imaging. Follow-up revealed complete functional myocardial recovery with normalisation of ventricular systolic and diastolic functions on serial echocardiograms.
