Abstract: Intrauterine growth retardation is an important problem in pediatrics, as it is an integral indicator of intrauterine dysfunction. Purpose: to study the features of the clinical and functional state of the cardiovascular system in newborn children born with various types of intrauterine growth retardation. Material and research methods: 70 newborns were examined. All children were divided into 2 groups: the 1st (main) amounted to 50 newborns with IUGR, of which: 1a - with the symmetric version of IUGR - 25, 1b - with the asymmetric version of IUGR - 25 children, in the 2nd group (comparisons) 20 premature infants without IUGR were included. All newborns underwent an echocardiographic examination of the heart. Results: on the basis of clinical and instrumental studies, the features of the clinical and functional state of the cardiovascular system in newborn children born with various types of intrauterine growth retardation are presented. In children who had different types of intrauterine growth retardation, significantly significant features of cardiac activity and morphological and hemodynamic parameters of the heart at birth were proved. Children with a symmetric variant of IUGR are characterized by a slowed heart rhythm, which was recorded significantly more often than in children with a symmetric variant of IUGR.
