It is recognized that chronic alveolar hypoxia is the major cause of pulmonary hypertension
in chronic respiratory diseases [1]. Accordingly, this form of secondary pulmonary …

To determine the frequency and correlates of pulmonary hypertension in sleep-disordered
breathing, pulmonary artery pressure, lung function and arterial blood gases were measured …

The prognostic value and the evolution of pulmonary hypertension (PH) in patients with
markedly hypoxemic chronic obstructive pulmonary disease (COPD), treated or not with long …

Study objective Unsuspected sleep-related respiratory events are common in patients with
severe pulmonary disease. Sleep in patients with primary pulmonary hypertension (PPH) …

The aim of this review was to analyse the effects of intermittent hypoxia (IH) on pulmonary
haemodynamics, comparing results of animal experiments with results of clinical studies. In …

The prognostic value of the presence and degree of pulmonary arterial hypertension (PAH)
in chronic obstructive pulmonary diseases (COPD) has been well established by recent …

Oxygen desaturation occurs during sleep in some patients with COPD. To investigate the
effects of these hypoxemic episodes on the pulmonary vasculature, we studied four patients …

It has been hypothesized but not firmly established that sleep-related hypoxaemia could
favour the development of pulmonary hypertension in chronic obstructive pulmonary …

The development of secondary pulmonary hypertension (PH) as a result of pulmonary
disease, both in adults and children, considerably worsens prognosis. Chronic hypoxia …

The aim of the present study was to compare the evolution of pulmonary haemodynamics
and of arterial blood gases in chronic obstructive pulmonary disease (COPD) patients with …
