To determine how long-term treatment with continuous positive airway pressure (CPAP)
affects cardiac autonomic function, we measured RR interval (RRI), respiration, and blood …

To determine the long-term effects of continuous positive airway pressure (CPAP) therapy
on cardiovascular variability, we measured RR interval (RR), systolic blood pressure (SBP) …

Background Cardiac autonomic tone after long-term continuous positive airway pressure
therapy in patients with obstructive sleep apnea remains unexplored. Methods Thirty …

The effect of positive airway pressure treatments in different modalities on the cardiovascular
consequences of the disease in sleep apnea patients is still unclear. We aimed to compare …

Background: Cyclic variation of the heart rate is observed during apneic spells in obstructive
sleep apnea (OSA). We hypothesized that autonomic changes would affect frequency …

Baroreflex control of heart rate during sleep (baroreflex sensitivity; BRS) has been shown to
be depressed in obstructive sleep apnoea (OSA), and improved after treatment with …

The role of the arterial baroreflex in the cardiovascular changes associated with the
obstructive sleep apnea syndrome (OSAS), and the effect of nasal continuous positive …

Patients with heart failure or OSA (obstructive sleep apnoea) have reduced HF-HRV (high-
frequency heart rate variability), indicating reduced cardiac vagal modulation, a marker of …

Objectives We examined the effect of continuous positive airway pressure (CPAP) treatment
for sleep apnea on cardiac contractility, heart rate variability, and hemodynamics at rest and …

Introduction Obstructive Sleep Apnea (OSA) is a major risk factor for cardiovascular disease.
The goal of this study was to demonstrate whether the use of CPAP produces significant …
