title: The cardiomyopathy in infants of streptozotocin-induced diabetic female rats.
abstract: Transient hypertrophic cardiomyopathy has been described in human infants of diabetic mothers. The purpose of this study was twofold: first, to document the features of cardiac hypertrophy in newborns of female rats with streptozotocin-induced diabetes and second, to investigate the natural history of this cardiomyopathy. Marked asymmetrical septal hypertrophy with hypertrophy of myocytes was observed in newborns of diabetic female rats, whether or not the mothers received daily administration of NPH insulin. The abnormal cardiac morphology was no longer apparent 4 weeks after birth. Thus, in this model, the asymmetrical septal hypertrophy was secondary and was not a manifestation of genetically transmitted hypertrophic cardiomyopathy.
