No results posted yet for this study

Summary

Chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death in the United States. There is no cure and the disease gets worse over time. Although it usually occurs in people who smoke cigarettes, researchers do not know exactly how smoking leads to COPD. This study will compare blood and tissue samples from smokers and nonsmokers with and without COPD to determine why some COPD symptoms occur in some people and not others.
