Simple bed adjustment may ease dangerous high blood pressure in autonomic failure
NCT ID NCT04502225
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether raising the head of the bed can help lower high blood pressure that happens when people with autonomic failure lie down. About 44 adults aged 18-85 with this condition will be studied overnight. The goal is to see if gravity reducing blood return to the heart can safely lower blood pressure without medication.
