Treating Women’s Sleep Apnea May Lower Heart Death Risk

People who have obstructive sleep apnea (OSA) stop breathing many times during the night. It is much more common in men than in women.

The struggle to start breathing again causes sufferers to snore loudly, snort, or gasp. That often keeps their bed partners from getting rest.

But there’s a greater danger to sleep apnea. It’s a major stress for the heart.

Studies in men have shown that OSA greatly increases the risk of events like heart attacks and strokes.

Researchers weren’t sure if sleep apnea also increased those risks in women or how much treatment of the condition would help.

The new study, which followed more than 1,100 women in Spain for an average of five years, found that women with untreated, severe sleep apnea had 3.5 times the risk of dying from a heart problem or stroke compared to women without the condition.

But treating those breathing interruptions with a machine or an oral device to hold the throat open, appeared to even their odds.

“I thought this was a good, quality study. It was well designed,” says Milena Pavlova, MD, a neurologist at Brigham and Women’s Hospital in Boston.

“It’s a good thing that they focused on women because a lot of previous research, by taking all comers, ends up having a much higher number of men,” says Pavlova, who studies sleep disorders in women, but was not involved in the research.

“Now we know that sleep apnea is associated with worse [heart disease and stroke] outcomes for women,” and that treatment is associated with reductions in those risks, she says.
