SAN DIEGO - ResMed says a convincing new CPAP study by doctors in Germany and Australia shows that sleep apnea causes hypertension (high blood pressure).

The study confirms and extends the findings of previous research, which has demonstrated that patients using CPAP at night experience significant falls in daytime blood pressure.

In the new study, the use of effective CPAP reduced mean blood pressure by 10mm of mercury versus a group of patients who used ineffective CPAP.

“This implies that unless CPAP levels are adequate the associated improvement in cardiovascular morbidity is not present,” according to ResMed. The study estimates that the reduction in blood pressure would reduce coronary heart disease by 37% and stroke risk by 56%.
