Abstract:

This article reviewed the definition of chronic obstructive pulmonary disease (COPD) in Global Initiative for Chronic Obstructive Lung Disease (GOLD) over the years, from which it can be seen that our understanding of the nature of COPD has gradually deepened and comprehensively. However, there are still some deficiencies in definition of COPD, including airway inflammation, etiology, disease heterogeneity, etc. The comorbid diagnosis and intervention of COPD requires multidisciplinary collaboration.

Key words: Global Initiative for Chronic Obstructive Lung Disease, Chronic obstructive pulmonary disease, Multimorbidity
