  • Title: COPD: clinical phenotypes.
    Author: Petty TL.
    Journal: Pulm Pharmacol Ther; 2002; 15(4):341-51. PubMed ID: 12220938.
    Abstract:
    Different phenotypic presentations in advanced stages of COPD are less common than in years past because of therapies that alter the manifestations of disease. Early stages of COPD are often asymptotic, but may present as asthma, chronic bronchitis, emphysema or combinations. Unusual presentations at young age are not common, but may be dramatic.
