The STAND-UP Study
What this study is about
Orthostatic hypotension (OH) and orthostatic intolerance (OI) are common conditions where blood pressure drops when standing up, causing dizziness, fainting, or fatigue. These affect up to 30% of adults over 65 and raise risks for heart disease, stroke, kidney problems, and more. Current medications often don't fully help and can cause side effects like high blood pressure when lying down.
View original scientific description
Orthostatic hypotension (OH) and orthostatic intolerance (OI) are common conditions where blood pressure drops when standing up, causing dizziness, fainting, or fatigue. These affect up to 30% of adults over 65 and raise risks for heart disease, stroke, kidney problems, and more. Current medications often don't fully help and can cause side effects like high blood pressure when lying down. The STANDUP study tests a new approach: using a minimally invasive procedure to open narrowed veins above the heart (supracardiac veins) that may block blood flow back to the heart. We believe fixing these blockages could improve blood pressure control and reduce symptoms. This is a 2-year study enrolling 100 adults (age 18+) with OH or OI that hasn't improved with standard treatments or is worsened by lying-down high blood pressure. What happens in the study? Participants get imaging (like X-rays and ultrasound) to check for vein narrowing. If needed, doctors use a thin tube (catheter) through a small skin puncture to inflate a tiny balloon (angioplasty) or place a small mesh tube (stent) to widen the veins. The procedure takes a few hours under local anesthesia, with monitoring for safety. Follow-up visits check symptoms, blood pressure, and quality of life at 2-4 weeks, 3 months, 6 months, 1 year, and 2 years. Who can join? Adults 18+ with diagnosed OH/OI not helped by meds. Must give informed consent. Not eligible if: Pregnant, breastfeeding, actively infected, or unable to take blood thinners. Possible benefits: Better standing tolerance, fewer symptoms, improved daily life, less need for meds, and new knowledge on vein issues in OH/OI. Risks: Rare but include bleeding, infection, stroke, vein clots, stent issues, radiation from imaging, or temporary symptom worsening. We'll monitor closely and report any problems. This single-arm trial (no placebo group) will compare before-and-after results to see if the procedure helps. No study drug costs; covered by insurance or clinic.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
