Title: A Multicentre 3 Year Longitudinal Prospective Study to Identify Novel Endpoints and Compare These With Forced Expiratory Volume in 1 Second (FEV1) for Their Ability to Measure and Predict COPD Severity and Its Progression Over Time
Brief Summary: This is a 3 year longitudinal study to identify novel endpoints and compare these with standard measures such as forced expiratory volume in 1 second (FEV1) for their ability to measure and predict COPD (Chronic Obstructive Pulmonary Disease) severity and its progression over time. Control subjects (smokers and never smokers) will be recruited as comparators with the COPD subjects.
