Objective: to reveal the adaptive features of the cardiovascular system in newborn infants with intrauterine growth retardation (IUGR) on the basis of a clinical instrumental study.Subjects and methods. A study group included 100 newborn infants with IUGR; a control group consisted of 40 babies with normal anthropometric measurements at birth. Medical history and clinical data and electrocardiographic and echocardiographic findings were analyzed.Results. All the examinees with IUGR had manifestations of cardiovascular system dysadaptation. There was a high rate of electrocardiographic changes, such as cardiac arrhythmias; low voltage; systolic overload of the right heart and left ventricle; signs of ventricular hypertrophy; and transient myocardial ischemia. The specific features of cardiac hemodynamics were decreased sizes of the left ventricle, lower parameters of its systolic function, and longer functioning of fetal communications.Conclusion. IUGR is associated with the development of cardiovascular system dysadaptation syndrome, which is due to prior perinatal hypoxia. The findings necessitate a follow-up of children by involving a cardiologist.
