Dysfunction of Right Heart in Attack Period of Bronchial Asthma in Children

V.А. Kondratiev, А.V. Reznik, Ye.V. Kunak

Abstract


There were performed Doppler echocardiography investigations of functional state of the right heart in 42 children aged 5–17 years old in attack period of bronchial asthma of moderate to severe degree. Changes of intra-cardiac hemodynamics of the right heart in children in attack period of bronchial asthma were characterized by disturbance of systolic and diastolic function of the right ventricle and right atrium. Combined systolic-diastolic variant of the right ventricle dysfunction was typical for attack period of bronchial asthma in children and developed in 95.5 % of cases. Elevation of pressure in pulmonary artery was typical and significantly more often occurred in severe asthma attack, herewith pulmonary hypertension of the second degree predominated.
