Introduction: Chronic inflammation of the tonsils leads to a deterioration of local and general immunity, as well as the development of damage to other organs and systems of the child’s body. One of the most common is non-inflammatory pathology of the cardiovascular system of tonsillogenic origin. The development of tonsillogenic processes in the body is due to both toxic-infectious, allergic effects of streptococcal infection, and certain risk factors for secondary lesions of the cardiovascular system on the background of chronic inflammation of the palatine tonsils.

Aim: The study was to identify the influence of certain factors on the development of cardiac pathology on the background of chronic tonsillitis in children.

Materials and methods: 45 children aged 13 to 18 years with a diagnosis of chronic tonsillitis, group I – 24 patients with chronic tonsillitis, group II – 21 patients with secondary cardiomyopathy and chronic tonsillitis were examined.

Results: The study: the pathology of pregnancy was significantly more common in mothers of children with secondary heart disease, in contrast to mothers of group I ((33.33 ± 9.83)% and (61.9 ± 9.87)% in groups I and II, respectively ). It was found that (33.33 ± 10.54) % of children with diseases of the cardiovascular system were born to parents older than 35 years, while this figure in group I was (12.50 ± 6.90) %, (p < 0.05). In addition, the premorbid background (23.81 ± 9.52) % (p <0.05) of children with tonsillogenic cardiomyopathies was complicated by parental cardiovascular disease. Analysis of the duration of breastfeeding showed that the majority of patients of group II had early artificial feeding – (57.14 ± 11.07) % against (33.33 ± 9.83) % among patients of group I.

Conclusions: In children with chronic tonsillitis and secondary cardiopathy, it was found that cardiovascular diseases of parents, late age of parents at birth (over 35 years), pathology of pregnancy and perinatal period, early breastfeeding were found in more patients compared to the group I. The presence of these risk factors in the history of patients with chronic tonsillitis may contribute to secondary heart disease, which should be considered in the diagnosis and treatment of patients with this pathology.
