Title: Genetic Epidemiology of Chronic Obstructive Pulmonary Disease (COPDGene)
Brief Summary: Chronic obstructive pulmonary disease (COPD) is a long-term lung disease that is often caused by cigarette smoking. The purpose of this study is to evaluate whether certain genetic factors predispose some smokers to develop COPD more than others.

* Male or female patients 40 years of age or older.
* Smoking history of at least 10 pack years.
* Diagnosis of COPD with post bronchodilator FEV1 less than or equal to 70% of predicted normal and FEV1\<70% of FVC and on stable respiratory medication.

Exclusion Criteria:

* Significant diseases other than COPD which in the opinion of the investigator may put the patient at risk or influence the patients ability to participate.
* Myocardial infarction in past 6 months.
* Unstable or life threatening arrhythmia in past year.
* Hospitalization for NYHA heart failure class III or IV in past year.
* Active tuberculosis.
* Asthma.

* Any illness expected to cause mortality in the next 3 years
* Active pulmonary infection, including tuberculosis
* History of pulmonary embolism in the past 2 years
