Chronic obstructive pulmonary disease in patients with chronic thromboembolic pulmonary hypertension: Prevalence and implications for surgical treatment outcome.

Objective: The aim of our study was to investigate the prevalence of chronic obstructive pulmonary disease (COPD) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) and examine their impact on the results of pulmonary thrombendarterectomy (PEA).

Methods: We enrolled 136 patients with CTEPH who scheduled for elective PEA. Pulmonary function tests (PFTs) including full-body plethysmography with bronchodilation test and lung diffusion capacity assessment were performed in all patients prior to surgery treatment.
