Within the chronic obstructive pulmonary disease (COPD) spectrum, lung emphysema presents, as a primarily histopathologic feature, the destruction of pulmonary parenchyma and, accordingly, an increase in the airflow ...

Little information exists regarding the epidemiology of the chronic bronchitis phenotype in unselected chronic obstructive pulmonary disease (COPD) populations. We examined the prevalence of the chronic bronchitis phenotype ...

The diagnosis of chronic obstructive pulmonary disease (COPD), a global health problem, is challenging in resource-constrained settings. Spirometry with an obstructive pattern after the administration of bronchodilators ...

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airway obstruction resultant from an augmented inflammatory response of the respiratory tract to noxious particles and gases. Previous reports ...

OBJECTIVE. This article presents the results of a cross-cultural reproducibility and test–retest reliability study of a Brazilian version of the Role Checklist, in a population with chronic obstructive pulmonary disease ...

Introduction: The impact of pulmonary hypertension (PH) on exercise tolerance in chronic obstructive pulmonary disease (COPD) has not been fully elucidated. It is necessary to characterize pulmonary hemodynamics in patients ...

Within the chronic obstructive pulmonary disease (COPD) spectrum, lung emphysema presents, as a primarily histopathologic feature, the destruction of pulmonary parenchyma and, accordingly, an increase in the airflow ...
