Background: Sleep is associated with important adverse effects in patients with chronic
obstructive pulmonary disease (COPD), such as disturbed sleep quality and gas exchange …

Purpose Non-sleepy sleep-disordered breathing (SDB) is increasingly recognized as an
important clinical subtype. The association between non-sleepy SDB and cardiovascular …

Background: There is increasing interest in cardiovascular co‐morbidities of chronic
obstructive pulmonary disease (COPD). Heart rate turbulence (HRT) and phase‐rectified …

Background There is growing evidence from animal models that intermittent hypoxemia (IH)
may induce dyslipidemia. Altered lipid metabolism may contribute to the increased …

OBJECTIVES: Recent studies suggest that persons with congestive heart failure (CHF) may
be at higher risk for the short-term effects of air pollution. We carried out this daily diary panel …

Aim: We investigated whether nocturnal intermittent hypoxia, a surrogate marker for
obstructive sleep apnea, is associated with metabolic syndrome and its components among …

Rationale: Nocturnal hypoxemia and sympathetic/parasympathetic imbalance might
contribute to the occurrence or atrial fibrillation (AF) in patients with obstructive sleep apnea …

Some patients with chronic obstructive pulmonary disease (COPD) experience transient
arterial hypoxemia (TAH) during rapid eye movement (REM) sleep. To examine the effect of …

Air travel and altitude stays have become increasingly frequent within the overall population
but also in patients suffering from chronic obstructive pulmonary disease (COPD), which is …

Background: Nocturnal hypoxemia, characterized by abnormally low oxygen saturation
levels in arterial blood during sleep, is a significant feature of various pathological …
