Material and methods. 125 patients with COPD in hospital - 123 (98.4%) men and 2 (1.6%) women with an average age of 64.9±0.7 (8.2) years were examined. All patients underwent physical examination, a survey on standardized questionnaires CAT and mMRC and spirography. Results. According to GOLD 2007 classification, patients were distributed as follows: GOLD I - 6.4%, GOLD II - 29.6%, GOLD III - 43.2%, GOLD IV - 20.8%. According to the ABCD GOLD 2011 classification, 4% of patients were classified as type C and 96% as type D, and 3.2, 11.2, 0.8 and 84.8%, respectively, in ABCD GOLD 2017 redistribution.
