Abstract

In 2020, COPD was the third leading cause of death worldwide. Lung function is central for the diagnosis of this disease, and COPD severity is still partially classified based on airflow obstruction, which can range from "mild" (GOLD 1 group, FEV1 >= 80% predicted) to "very severe" (GOLD 4, FEV1 <30% predicted). However, the term "mild COPD" needs to be carefully analyzed. Several studies have shown that even in the presence of a mild obstruction, patients can have significant symptoms, physiological deterioration, evidence of emphysema, and suffer from recurrent exacerbations. Small airways pathology significantly correlates with the presence of symptoms, and it has been demonstrated that the onset of bronchiolitis occurs earlier than that of emphysema. These damages have long been known to not be detectable with conventional tests, and exclusive reliance on spirometry is not enough to adequately study and stage a patient with "mild COPD." Therefore, early identification of COPD is of utmost importance in the light of modifying the natural course of the disease. However, patients with early lung damage are yet to be included and studied in interventional clinical trials.
