Participants between the ages of 30-55 with at least 10 pack-year smoking history will be enrolled into a observational longitudinal cohort.
The aim of this project is to develop a disease progression cohort within the University of Michigan Health System to capture pulmonary function, symptom assessments and quantitative imaging among patients at risk for or with an established diagnosis of COPD, focusing however on early COPD (age 30-55 and GOLD stage 0,1, 2, and prism).
