About this study

Many persons with autonomic failure often have high blood pressure when lying down (supine hypertension). This study is exploring the impact of decreased venous return to the heart (achieved by raising the head of the bed) to lessen supine blood pressure. If decreased venous return to the heart is effective at lowering supine blood pressure, these approaches may be utilized to treat supine hypertension non-pharmacologically. Raising the head of the bed decreases the amount of blood returning to the heart due to the effects of gravity. In this case, the decreased blood return to the heart may decrease blood pressure.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
