STAND-UP: opening narrowed veins above the heart to help low blood pressure when standing

Official title: Evaluation of Supracardiac Venous Angioplasty and Stenting on Ortho- Static Intolerance and Orthostatic Hypotension - The STANDUP Study

Run by St. Francis Hospital, New York · NCT07195903 · Data updated 2026-11-12

This study will try a minimally invasive catheter procedure to open narrowed supracardiac veins and see if that improves dizziness, fainting, or low blood pressure in adults with orthostatic hypotension or orthostatic intolerance that hasn't improved with standard treatments.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with diagnosed orthostatic hypotension or orthostatic intolerance not adequately helped by standard treatments or complicated by supine hypertension, who can consent and undergo imaging and catheter procedures, are the intended participants.

Probably not a fit

Patients without demonstrable supracardiac vein narrowing, those who are pregnant or breastfeeding, people with active infection or coagulopathy, or those whose symptoms are well controlled on current therapies are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study enrolls 100 adults with orthostatic hypotension or orthostatic intolerance that is refractory to standard medical therapy or complicated by high blood pressure when lying down. Participants undergo imaging (X-ray, ultrasound) to look for narrowed veins above the heart and, if narrowing is found, may receive endovascular angioplasty or stenting via a catheter. Patients are followed for two years to track standing blood pressure control, symptom changes, and procedure safety, including monitoring for supine hypertension and vascular complications. The trial is single-center and targets people whose symptoms persist despite usual care.

Why it matters

Potential benefit: If successful, opening narrowed supracardiac veins could improve standing blood pressure and reduce dizziness, fainting, and fatigue for patients with refractory orthostatic disorders.

How similar studies have gone: Prior work on opening central veins for orthostatic symptoms is limited to small case series and pilot reports that suggest possible symptom improvement but lacks large randomized evidence.
