Continuous positive airway pressure (CPAP), which is used to ease the symptoms of obstructive sleep apnoea (OSA), can help reduce the death risk for women with the condition.
OSA affects up to 3% of middle-aged women and previous research has shown a link between OSA and the risk of death from heart problems.
A new study, published in the Annals of Internal Medicine, studied 1,116 women who were referred for evaluations of OSA to two sleep medicine clinics in Spain between 1998 and 2007.
The findings revealed that women with untreated, severe OSA had increased risk of death from heart problems. However, if women with OSA use CPAP treatment, the risk of death decreases to a similar rate seen in women without OSA.
