Background. The problem of early diagnosis of cardiovascular diseases in children is relevant throughout the world and in Ukraine, as in childhood the health and quality of life of an adult are formed. The psychoemotional stress in junior children as well as increasingly complicating school curriculum, information overload with electronic gadgets, increased frequency of colds in children cause physical inactivity. In addition, infectious agents have a toxic effect on the myocardium, altering its functional state. All these together adversely affect the formation and development of the cardiovascular and respiratory systems of children. The aim was to study the functional reserve of the myocardium in junior children, depending on the frequency of upper respiratory tract infection (URTI). Materials and methods. The study examined 1109 children aged 6 to 9 years old. The URTI incidence was analyzed depending on the age. In the study, the children were divided into two groups. Group 1 consisted of the children with URTI — 210. Group 2 involved the children with occasional URTI — 899. Results. Among 210 surveyed children with upper respiratory infections 171 schoolboys (81.4 %) had reduced functional reserve of the myocardium, which is consistent with findings from other studies. In children aged 7 and 9 years old, the number of reduced functional reserve of the myocardium varies from 70 to 82 % in seven-year children, among the schoolboys aged 6 and 8 years old the incidence of reduced functional reserve of the myocardium increased from 83 to 100 % in six-year children. Conclusions. Children with URTI have a reduced functional reserve of the myocardium. Children with episodic URTI have higher rates of functional reserve of the myocardium, therefore reducing the incidence of URTI will lead to the improvement of the myocardium functional state.
