[The medical social importance of functional disorders under chronic obstructive disease of lungs]

The chronic obstructive disease of lungs is considered as important problem of modern public health system. The disease is increasingly keenly reflected in agenda of our society, economic and social sphere of the state. The steadily progressing course of disease, disability and increasing economic costs assigns task of finding and improving diagnostic methods in real clinical practice. The purpose of the study is to assess the medical social significance of new approaches to studying functional status of patients with chronic obstructive disease of lungs in routine clinical practice. The sampling of 105 males were examined: 64 patients with chronic obstructive disease of lungs and 41 volunteers from control group without any diseases of respiratory system. All examined patients underwent spirometry, sixth minute step test, analysis of heart rate variability and test with external peripheral vascular occlusion. The study results established high level of importance of complex assessment of functional status of patients in routine clinical practice. The patients with chronic obstructive disease of lungs with respiratory failure demonstrated persistent hyperactivity of ergoreflex during test with external peripheral vascular occlusion. Therefore, method of assessing ergoreflex according to heart rate variability indices is applicable in clinic and has perspectives of implementation as mode of additional diagnostics of functional disorders.
