CPAP therapy may improve blood pressure in resistant high blood pressure

Obstructive sleep apnea (OSA) has been linked to high blood pressure (HTN). In fact, one cause of reversible HTN is untreated OSA. And sometimes we see improvement in HTN with treatment of OSA, especially severe OSA. Here is a study that showed just that. Researchers studied patients with resistant HTN and moderate-to-severe OSA. The results showed that blood pressure dropped significantly after 6 months of CPAP therapy, compared to those patients who did not receive CPAP therapy.
