Study Summary

This trial aims to learn if using CPAP can lower blood pressure for people with autonomic failure and high blood pressure when lying down.

Who is the study for?
This trial is for adults aged 40-80 with autonomic failure conditions like multiple system atrophy or Parkinson's disease, who experience a significant drop in blood pressure upon standing and high blood pressure when lying down. Excluded are those intolerant to CPAP, unable to stand, recent smokers, pregnant women, or individuals with unstable heart disease.Check my eligibility
What is being tested?
The study tests if continuous positive airway pressure (CPAP) can treat nighttime high blood pressure in patients with autonomic failure. Participants will undergo active CPAP, sham CPAP (placebo), and sleep with the bed tilted head-up during separate sessions at Vanderbilt Clinical Research Center.See study design
What are the potential side effects?
While not explicitly stated here, common side effects of using CPAP may include discomfort or irritation from the mask, dry nose or throat, nasal congestion, headaches and sometimes stomach bloating.
