People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study in the November 2008 issue of American Journal of Respiratory and Critical Care Medicine.
Their findings suggested that minimally symptomatic OSA is a cardiovascular risk factor to a degree not previously known.

People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study from the Oxford Centre for Respiratory Medicine in the United Kingdom.
“It was previously known that people with OSA severe enough to affect their daytime alertness and manifest in other ways are at increased risk of cardiovascular disease, but this finding suggests that many more people — some of whom may be completely unaware that they even have OSA — are at risk than previously thought,” said lead author of the study, Malcolm Kohler, M.D.

As the new school year approaches, the National Sleep Foundation (NSF) and Awake In America encourage parents and kids to put healthy sleep on the list of back-to-school necessities. NSF and Awake In America recommend gradually adjusting sleep schedules in order to be alert and energized as well as to assure optimal learning, participation and health.
“Kids tend to sleep and wake up later during the summer, making the transition to the school-year sleep schedule difficult,” explains Awake In America’s President, Michele Narcavage. “As tempting as it is to enjoy sleeping late in the final days of summer break, getting up earlier for school will be much easier if kids begin adjusting their sleep schedules now.”

Researchers found that patients with obstructive sleep apnea, who were compliant with their CPAP therapy, experienced an average 2mm/Hg drop in both systolic and diastolic blood pressure at the end of the year when compared to patients who did not use the CPAP machine.
