Identification of clinical phenotypes using cluster analyses in COPD patients with multiple comorbidities.

BioMed research international - 1 Jan 2014

Burgel Pierre-Régis, Paillasseur Jean-Louis, Roche Nicolas

Abstract excerpt

Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation, the severity of which is assessed using forced expiratory volume in 1 sec (FEV1, % predicted). Cohort studies have confirmed that COPD patients with similar levels of airflow limitation showed marked heterogeneity in clinical manifestations and outcomes. Chronic coexisting diseases, also called comorbidities, are...
