Description
COPD (chronic obstructive pulmonary disease) was relatively uncommon a few generations ago, but it is now a major public health problem, affecting more than 20 million Americans and causing 5% of all deaths among adults in the U.S. Public education regarding the disease, research on its pathogenesis and treatment and the development of effective therapies have not kept pace with the growth of COPD. As a result, this condition stands out as a prime opportunity for substantial improvements in awareness, scientific knowledge, and patient care over a relatively short period of time.
