AIMS: To determine the role of serum insulin-like growth factor I (IGF-I) in predicting the occurrence of septal hypertrophic cardiomyopathy in infants of mothers with diabetes. METHODS/MATERIALS: In this prospective study, 100 pregnant women (50 with diabetes and 50 controls), matched for age and race, were studied. One intrapartum blood sample was taken at 28 weeks of gestation from both groups of mothers and another sample at delivery. All samples were analysed for maternal IGF-I by an enzyme linked immunosorbent assay method. A chest radiograph and an electrocardiogram were performed on the babies of the mothers with diabetes within the first 24 hours of life. An echocardiogram was performed in the first 3 days of life to look for septal hypertrophy and to measure the myocardial thickness. RESULTS: In the six cases of neonatal septal hypertrophic cardiomyopathy, all the mothers had greatly raised IGF-I concentrations of more than 400 ng/ml at the time of delivery compared with a mean (SD) of 302 (25) ng/ml in control mothers. CONCLUSIONS: In the present study a crude analysis revealed that increased IGF-I concentrations correlate with neonatal septal hypertrophic cardiomyopathy.
