[Integrated assessment of the functional capacities of the cardiovascular system in children from an industrial town].

The findings suggest that ambient air pollution in Angarsk causes an increase in poor changes in the cardiovascular system of children and a rise in their morbidity. Under long-term high ambient air pollution, the increased nonspecific resistance reduces in children with age, as evidenced by the preservation of high morbidity rates (including those of respiratory diseases), the larger proportion of children with cardiovascular disorders, as well as the indices of physical development and hemodynamics. At the same type, the integrated indices of the body's condition permit determination of the degree and significance of abnormalities in both an individual and the study cohort and provide a possibility of assessing the risk of poor changes.
