CPAP use may help lower blood pressure, study says

VALENCIA, Spain – Sleep apnea sufferers with hard-to-control blood pressure may find an ancillary benefit to CPAP therapy: Spanish researchers say it may lower resistant blood pressure. In a study published Dec. 11 in the Journal of the American Medical Association, researchers examined sleep apnea patients taking three or more blood-pressure medications. Those who used CPAP for 12 weeks saw a drop in their diastolic blood pressure, according to the study, partly funded by Philips Respironics. “The prevalence of sleep apnea in patients with resistant high blood pressure is very high,” said head researcher Miguel-Angel Martinez-Garcia of Valencia’s Polytechnic University Hospital. “This treatment increases the probability of recovering the normal nocturnal blood pressure pattern.”
