New Study Shows CPAP Reduces Risk of Cardiovascular Death in Women With Sleep Apnoea

Severe obstructive sleep apnea was associated with a risk of cardiovascular death in women, but continuous positive airway pressure (CPAP) seemed to reduce the risk, according to a small Spanish study.

In a 116-patient, observational study, those with severe obstructive sleep apnea had a cardiovascular mortality rate of 3.71 per 100 person-years compared with the control group’s rate of 0.28 per 100 person years, Francisco Campos-Rodriguez, MD, from Valme University Hospital in Seville, Spain, and colleagues found.

Women with mild to moderate apnea had a mortality rate of 0.94 per 100 person-years (P=0.034 compared with the control group), they reported in the Annals of Internal Medicine.

Despite prevalence data suggesting that 2% to 3% of middle-age women have obstructive sleep apnea, most of the studies on both apnea and cardiovascular effects have been done exclusively in men. The researchers were interested in investigating this issue in a large group of women.
