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.

A comparison of two diagnostic methods used to detect deep vein thrombosis, or DVT — a blood clot in a deep vein in the leg or thigh — of the lower extremities indicates that a simpler method, with wider availability, has rates of DVT detection that are equivalent to a more complex method, according to a study in the October 8, 2008 issue of JAMA.
The imaging technique, compression ultrasonography, is a highly accurate method for the detection of DVT and has replaced other diagnostic methods in common practice. Two ultrasonography diagnostic methods often used are two-point and whole-leg.

When asthmatics are awake, they can turn to their inhalers to open their airways. But when they sleep, many of them continue to struggle with breathing — and an understanding of their sleep-related problems may help doctors better diagnose and treat their patients’ asthma, according to new University of Michigan Health System research.
Symptoms of sleep apnea and other breathing problems during sleep are common among people with asthma, according to the research presented at the American Thoracic Society’s 2005 International Conference.

Interesting Apnea Statistics
~~ Apnea in United States ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
~~ Apnea around the world ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
