  • A Study of Continuous Positive Airway Pressure Treatment for Obstructive Sleep Apnea to Prevent Cardiovascular Disease Rochester, MN

    Obstructive Sleep Apnea (OSA) is a condition in which a person stops breathing for several seconds at a time due to relaxation of the throat muscles. This can occur many times during sleep and is known to cause sleepiness and poor concentration during the day. Research indicates that OSA may be a modifiable risk factor for cardiovascular disease due to its association with hypertension, stroke, heart attack and sudden death. The standard therapy for symptomatic OSA is continuous positive airway pressure (CPAP). CPAP has been shown to effectively reduce snoring, obstructive episodes and daytime sleepiness and to modestly reduce blood pressure ...
