Structure of unoperated congenital heart diseases in children of Zabaikalsky Territory

The aim of the research is to study the morbidity by appealability and some characteristics of congenital heart diseases in children of Zabaikalsky Territory. Material and methods. A retrospective clinical and anamnestic analysis of children with congenital heart diseases without surgical treatment, who were hospitalized, was carried out. The analysis included 3 year-observation. CHD diagnosed is an inclusion criterion; while surgical treatment of heart diseases is exclusion criterion. Statistical data processing was carried out using Microsoft Excel 2007, Statistica v.10.0 software package. χ2 test (Pearson) was used to compare two independent groups by qualitative characteristics. The results were considered statistically significant (reliable) at the achieved significance level of p <0.05. Results. In Zabaikalsky Territory, approximately 200 children with congenital heart disease without surgical treatment are hospitalized annually; the average age is 3 years. Fifty-three per cent of children applied for inpatient care for the first time, 44% of them were children at their first year. Gender distribution indicates the highest incidence of the pathology in girls. In CHD structure, atrial septal defects are on the first place, while interventricular septal defects are on the second. Combination of ASD and IVSD was observed with approximately equal frequency. Chronic heart failure associated with CHD was registered in 77% of children. In most cases CHF, stage 1, was diagnosed (63%). In 2/3 of cases, pulmonary hypertension of various severity was detected. Analysis of place of residence of children with CHD in the Zabaikalsky Territory shows that children from areas with the highest population density are hospitalized more often. Conclusion. The problem of congenital heart diseases in children of Zabaikalsky Territory is of current importance due to the widespread prevalence and high specific gravity among all internal organ defects in children of this region.
