Due to tight functional interrelation between respiratory apparatus and blood circulation, exacerbation of bronchial asthma in children is associated with changes of cardiovascular system. Multifacetedness of this problem determines comprehensive approach to examination of children with bronchial asthma, involving most available methods of heart function evaluation: echocardiographic heart study with Doppler sonography and electrocardiography. Of great importance is investigation of systemic and pulmonary hemodynamics and microcirculation in bronchial asthma depending on its clinical course. It was found that children with exacerbation of bronchial asthma were detected with pulmonary hypertension, which had gradual regression after attack alleviation. During the remission stage, hemodynamics disturbances in lesser circulation were present in long-lasting and severe course of disease. However, the increase in the pulmonary blood flow parameters in patients only in the early period after attack can be regarded as a compensatory response from the lesser circulation to the decline in respiratory function indices. Therefore, despite the great achievements of science in the study of pathophysiological mechanisms and clinical features of bronchial asthma at different ages, it is necessary to continue further study of all aspects of bronchial asthma in children, because it is not as well studied as asthma in adults.
