A new study suggests that when prescribed by physicians in routine practise and used appropriately by patients, treatment for obstructive sleep apnoea (OSA) could reduce blood pressure in men with hypertension.

"All types of patients may benefit from this treatment, even those with other chronic medical conditions," said Bharati Prasad, MD, MS, the study's principal investigator. "It's important to now do a prospective study enrolling different types of patients with sleep apnoea."

How the study was done

The study, appearing in the issue of the Journal of Clinical Sleep Medicine, examined the effectiveness of obstructive sleep apnoea treatment on high blood pressure and diabetes control in 221 men with preexisting hypertension or type 2 diabetes and a new diagnosis of OSA. Participants received positive airway pressure (PAP) therapy upon treatment initiation.

Results show that both systolic and diastolic blood pressure decreased significantly with initiation of OSA treatment at both the first follow-up, 3-6 months after initiation, and the second follow-up, 9-12 months later.

According to the authors, this is the first study to examine the effectiveness of treatment of obstructive sleep apnea on routine measures of hypertension and diabetes control in a practise-based clinical setting. The results show the real-world effectiveness of OSA treatment on hypertension.
