Abstract
Objective: to study the time course of clinical, electrocardiographic (ECG), and echocardiographic changes during the first year of life in babies having different gestational ages who have a history of transient myocardial ischemia.
Subjects and methods. A total of 46 infants, including 22 preterm and 24 full-term newborn babies with posthypoxic myocardial dysfunction, were examined. The time course of clinical, ECG, and echocardiographic changes during the first year of life in babies having different gestational ages who had a history of transient myocardial ischemia in the early neonatal period was traced. Reexamination one month later revealed differences in the ratio of atrial diameters that were significantly higher in the group of preterm infants. The left ventricular systolic functional parameters were also lower than those in the babies in the control group both after birth and at the end of the neonatal period. The most stable cardiac disorders that persist in the infants during the first year of life include a set of ECG changes in the process of ventricular repolarization concurrent with grade 1 diastolic dysfunction. A relationship was found between of the detected myocardial dysfunctions and the babies’ gestational age.
