[Progress in pre-chronic obstructive pulmonary disease].

Pre-chronic obstructive pulmonary disease (Pre-COPD) refers to individuals with chronic respiratory symptoms, structural abnormalities, and/or functional abnormalities, in the absence of airflow limitation, who may develop persistent airflow limitation over time. COPD is characterized by high prevalence and great heterogeneity and complexity. Early multidimensional identification and promotion of early prevention, management and treatment of Pre-COPD can help delay or halt the development of COPD, which has significant public health implications. This review aimed to summarize the definition, relevant cohorts, clinical trials, and other research progress in pre-COPD in order to improve the understanding of individuals with pre-COPD and improve early prevention and management of COPD.
