CATAMNESTIC OBSERVATION OF CARDIOVASCULAR STATUS IN PRETERM INFANTS
M.O. Gonchar, A.D. Boichenko
To identify peculiarities of the diastolic function development of the heart ventricles in preterm infants following clinical and instrumental examination in the neonatal period and in the process of catamnestic observation the study involved examination of 244 preterm infants at gestation age from 260-7 to 376-7 weeks. Control group comprised 100 healthy full-term infants. The study showed that peculiarities of the development of diastolic function of the heart ventricles in prematurely born children included diastolic dysfunction by the type of delayed relaxation, which is typical for the fetus, until the child reaches the postconceptual age of 39-41 weeks. Normalization of the diastolic function of the heart ventricles occured in 46/61 (75.41 ± 5.51%, p = 0.1·10-6) prematurely born children to 5-6 months of actual age, in 15/61 (24.59 ± 5.51%) children to 6-8 months of actual age. Spontaneous closure of open oval window up to the age of 1 year occurred in 22/32 (68.75 ± 8.19%, p = 0.009) full-term newborns and in 21/61 (34.43 ± 6.08%) preterm infants. Hemodynamically significant patent arterial duct in 58.82 ± 11.94% of children spontaneously closes during the first three months of life. The incidence of myocardial dysfunction in newborns from mothers with extragenital pathology increased to 89.39 ± 3.79% versus 76.67 ± 5.46%, p = 0.046 children born from healthy women. The presence of extragenital pathology in mothers, including cardiovascular disorders, is a risk factor for the development of cardiovascular diseases in preterm children.
Key words: preterm infants, myocardial dysfunction, catamnesis.
КАТАМНЕСТИЧНЕ СПОСТЕРЕЖЕННЯ СТАНУ СЕРЦЕВО-СУДИННОЇ СИСТЕМИ У ПЕРЕДЧАСНО НАРОДЖЕНИХ ДІТЕЙ
Гончарь М.О., Бойченко А.Д.
З метою визначення особливостей становлення діастолічної функції шлуночків серця у передчасно народжених дітей на підставі клініко-інструментального дослідження в неонатальний період та в процесі катамнестичного спостереження обстежено 244 передчасно народжені дитини зі строком гестації від 26 до 37 тижнів. Контрольна група – 100 здорових доношених новонароджених. За результатами дослідження встановлено, що до особливостей становлення діастолічної функції шлуночків серця у передчасно народжених дітей відноситься реєстрація діастолічної дисфункції за типом уповільненої релаксації, що є характерним для плода, до досягнення дитиною постконцептуального віку 39-41 тиждень. Нормалізація діастолічної функції шлуночків серця відбувається у 46/61 (75,41±5,51%, р=0,1·10-6) передчасно народжених дітей к 5-6 місяцю фактичного віку, у 15/61 (24,59±5,51%) дітей – к 6-8 місяцям фактичного віку. Спонтанне закриття відкритого овального вікна до віку 1 року відбувається у 22/32 (68,75±8,19%, р=0,009) доношених новонароджених та у 21/61 (34,43±6,08%) передчасно народжених дітей. У 58,82±11,94% дітей з гемодинамічно значущою ВАП відбувається її спонтанне закриття на протязі перших трьох місяців життя. Частота зустрічальності міокардіальної дисфункції у новонароджених від матерів з екстрагенітальною патологією зростає до 89,39±3,79% проти 76,67±5,46%, р=0,046 дітей народжених від здорових жінок. Наявність у матерів екстрагенітальної патології, в тому числі патології серцево-судинної системи, є факторами ризику розвитку серцево-судинних розладів у передчасно народжених дітей.
Ключові слова: передчасно народжені діти, міокардіальна дисфункція, катамнез.

С целью определения особенностей становления диастолической функции желудочков сердца у недоношенных детей на основании клинико-инструментального исследования в неонатальный период и в процессе катамнестического наблюдения обследовано 244 преждевременно рожденных ребенка со сроком гестации от 26 до 37 недель. Контрольная группа - 100 здоровых доношенных новорожденных. Установлено, что к особенностям становления диастолической функции желудочков сердца у недоношенных детей относится регистрация диастолической дисфункции по типу замедленной релаксации, что характерно для плода, по достижении ребенком постконцептуального возраста 39-41 недель. Нормализация диастолической функции желудочков сердца отмечается у 46/61 (75,41±5,51%, р=0,1·10-6) недоношенных детей к 5-6 месяцу фактического возраста, у 15/61 (24,59±5,51%) детей – к 6-8 месяцам фактического возраста. Спонтанное закрытие овального окна в возрасте 1 года зарегистрировано у 22/32 (68,75±8,19%, р=0,009) доношенных новорожденных и у 21/61 (34,43±6,08%) недоношенных детей. Спонтанное закрытие гемодинамически значимого ОАП у 58,82±11,94% детей происходит в течение первых трех месяцев жизни. Частота встречаемости миокардиальной дисфункции у новорожденных от матерей с экстрагенитальной патологией возрастает до 89,39±3,79% против 76,67±5,46%, р=0,046 детей рожденных от здоровых женщин. Наличие у матерей экстрагенитальной патологии, в том числе патологии сердечно-сосудистой системы, является факторами риска развития сердечно-сосудистых расстройств у недоношенных детей.
Ключевые слова: недоношенные новорожденные, миокардиальная дисфункция, катамнез.
