Background Pulmonary hypertension (PH) is a common complication of chronic obstructive
pulmonary disease (COPD). However, it is unknown whether the ratio of forced vital capacity …

In patients with systemic sclerosis, a ratio between forced vital capacity (FVC) and diffusing
capacity of carbon monoxide (DLCO, FCV%/DLCO%)> 1.5 might be a predictor of …

Carbon monoxide diffusion capacity (DLCO) is negatively associated with patient survival in
idiopathic pulmonary hypertension (PH), but is not included in the risk stratification score …

BACKGROUND Patients with pulmonary hypertension (PH) due to chronic lung disease
(Group 3 PH) have poor long-term outcomes. However, predictors of survival in Group 3 PH …

Background It is important to assess the prognosis of patients with chronic obstructive
pulmonary disease (COPD) and acute exacerbation of COPD (AECOPD). Recently, it was …

INTRODUCTION: The functional significance of pulmonary hypertension (PH) in COPD is
unclear. The purpose of the study was to define the prevalence, severity and associated …

COPD is frequently associated with mild to moderate pulmonary hypertension (PH).
However, a small subset of patients develops severe PH, which is currently …

Background The prognostic role of the arterial blood gas tension of carbon dioxide (PaCO 2)
in severe Chronic Obstructive Pulmonary Disease (COPD) remains unknown. The aim of …

A weak correlation between diffusing capacity of the lung for carbon monoxide (DLCO) and
emphysema has been reported. This study investigated whether impaired DLCO in chronic …

Background Patients with COPD who experience pulmonary hypertension (PH) have worse
mortality than those with COPD alone. Predictors of poor outcomes in COPD-PH are not well …
