Electrocardiographic changes in newborns from mothers with metabolic syndrome

Abstract

The aim: Analysis of electrocardiographic parameters in newborns from mothers with metabolic syndrome. Materials and methods: We conducted a prospective cohort trial of 125 newborns, which included the study of their anthropometric, clinical and laboratory indicators and, in particular, ECG parameters. The main group consisted of 40 children, born from mothers with diagnosed metabolic syndrome, the comparison group included 2 subgroups: 28 term newborn and 57 preterm, from mothers without metabolic syndrome. Results: In newborns from mothers with metabolic syndrome on a fragmentary ECG we revealed abnormal depolarization, manifested by changes in the ventricular complex – QRS expansion (p<0.001), impaired conduction (p = 0.004), changes of T wave (p<0.001) and prolonged QT interval (p<0.001). There are such risk factors for QT prolongation in neonates: disease cardiovascular system and disorders of lipid metabolism in mother, asphyxia at birth and electrolyte disorders (hypernatremia OR 0.97), weight too high to gestational age at birth in newborn (OR 2.97), increased blood pressure in the neonatal period (OR 1.07), artificial feeding (OR 3.01). Conclusions: Metabolic syndrome in women during pregnancy has a pronounced effect on the cardiovascular system of the newborn. The detected signs of cardiac dysfunction on the ECG can serve as early integrated indicators of metabolic syndrome and cardiovascular disease in children.
