The role of bacteria in exacerbations of COPD. A constructive view.

abstract：BACKGROUND:Pleural effusions frequently accumulate in patients with left-sided heart failure. However, our recent study in patients with idiopathic and heritable pulmonary arterial hypertension (PAH) demonstrated that pleural effusions frequently occur in patients with isolated right-sided heart failure (RHF). The obje...
