Pulmonary hemodynamics and diastolic function of right ventricle at isometric exercises in children with chronic bronchopulmonary pathology

Abstract

We studied pulmonary hemodynamics and right ventricular diastolic function in 300 healthy children and 392 children with chronic bronchopulmonary pathology in an isometric exercise. Using echocardiography were determined systolic, diastolic, mean, pulmonary artery pressure, total pulmonary resistance, diastolic function of the right ventricle. Defined normal values of reactivity of pulmonary hemodynamics and diastolic function of the right ventricle in an isometric load. In patients with chronic bronchopulmonary pathology set higher increase of systolic, diastolic, mean, pulmonary artery pressure, decrease diastolic reserve the right ventricle compared to the control. The worst violations of pulmonary hemodynamics and diastolic function of the right ventricle during isometric load observed in patients with chronic Infectious-inflammatory and interstitial lung disease.
