Approximately 3 % Of All Patients With COPD

Approximately 3 % of all patients with COPD have This factor. Initial displays at patients COPD with AAT-deficiency Occur on earlier periods of a life, than at patients without AAT - Deficiency. However, in the presence of destructions of fabrics, Connected with an emphysema, processes of regeneration of a fabric to the adequate form Are changed also balance of restoration of a pulmonary fabric it is broken. In the final The account, long superfluous a pulmonary fabric Comes to an end with development of an emphysema of lungs which is characterised Increase in alveoluses and structural damages . Change small is key The factor in development of irreversible loss of normal characteristics of streams Air at COPD. Because of structural changes in walls of bronchial tubes and aerodynamic resistance in departments Bronho-pulmonary system increases. In addition to it The progressing emphysema changes biomechanics of the certificate of breath, and Puffiness, hypoventilation and slime hyperproduction bring the additional The negative contribution to narrowing of an air line.
