摘要
Chronic obstructive pulmonary disease （COPD） is a heterogeneous disease with high morbidity and mortality. With increasing use of computed tomography in the assessment of patients with COPD, the presence of previously unrecognized radiological bronchiectasis is being identified. Accumulating evidence shows that bronchiectasis has an important impact on the natural history of COPD. Moderate-severe COPD with eomorbid bronchiectasis has more severe symptoms, higher frequency of exacerbations, and increased mortality Given the prognostic implications of bronchiectasis in COPD, its detection could serve as a guide to better management and eventually improved survival. Therefore, bronchiectasis was proposed as a comorbidity of COPD by Global Initiative for Chronic Obstructive Lung Disease （GOLD） updated 2014.
