[Nature and mechanism of hemodynamic changes in fetuses of mothers with various types of diabetes mellitus].

Doppler echocardiography of flow in the fetal aorta and the umbilical artery as well as fetal echocardiography performed in 61 pregnant females with diabetes mellitus revealed central intracardiac hemodynamic alterations as risk factors for the development of "diabetic" heart failure in newborns. Pregnancy--associated diabetes patients and females with diabetes of type I demonstrated a somewhat decrease in the fetal myocardial contractility which was evidently determined by metabolic alterations in the myocardium, macrosomia and disorders in the fetoplacental circulation.
