Mild apnea could boost cardiovascular risk

In this study, the risk of cardiovascular problems such as arterial stiffness was significantly higher in patients with minimally symptomatic obstructive sleep apnea. This finding suggests that many more people, some of whom may be completely unaware that they have OSA, are more at risk than previously thought.

Scientists suggests that a special breathing machine, known as a CPAP, may provide a cardiovascular benefit-- even to patients with mild sleep apnea.

The study appears in the American Journal of Respiratory and Critical Care Medicine.
