Objective: To analyze the clinical characteristics of imaging phenotypes in patients with AECOPD.

Methods: 180 patients with AECOPD who received treatment in the out-patient and inpatient department of Respiratory and Critical Care Medicine of Yinchuan First People's Hospital from January to August 2021,all patients received chest HRCT and filled in CAT, mMRC, HADS and PSQI questionnaires, according to the degree of emphysema and the thickness of bronchial tube wall on HRCT, they were divided into three groups: tracheitis type (A), emphysema type (E) and mixed type (M), to assess the difference between three groups.

Results: The BMI of group E and M was significantly lower than group A, but the smoking index was significantly higher than group A. The mMRC and CAT scores of group A and E were lower than group M, and there was no significant difference in HADS scores among the three groups, but the sleep quality of group M was the worst.

Conclusion: The prognosis for the group A was the most favorable. The symptoms of the group M were more pronounced, with a significant impact on daily life due to COPD, the extent of emphysema and thickening of the bronchial wall were particularly severe.
