Abstract

BackgroundIn the general population without COPD, indoor air pollution from biomass is a causal factor of cognitive impairment (CI). CI is also common in patients with tobacco smoke COPD and has been associated with hypoxemia and cardiovascular comorbidities. CI and its risk factors have not been evaluated in COPD patients living at high altitude, who experience greater hypoxemia and frequent exposure to wood smoke.MethodsPatients with COPD residing at high altitude with FEV1/FVC
