About this trial
Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea, cough, sputum production and/or exacerbations) due to abnormalities of airways (bronchitis, bronchiolitis) and/or alveoli (emphysema) that cause persistent, often progressive, airflow obstruction.
The presence of non-fully reversible airflow obstruction (FEV1/FVC \< 0.7 post-bronchodilation) measured by spirometry confirms the diagnosis of COPD
