Predicting blood vessel damage in large vessel vasculitis
This study uses PET and MRA scans to predict damage to large blood vessels in people who have or may have large vessel vasculitis (LVV). It aims to find at-risk patients early so they can get better care. You'll need to be willing to have both scans and come back for long-term check-ups.
Nanjing, JiangsuAges 18 years+ - NCT06647017Recruiting
Nerve stimulation to reduce blood loss during dialysis graft placement
This trial tests whether a gentle nerve stimulation device placed behind the ear can lower blood loss during surgery to place a dialysis graft (a tube for dialysis treatment). It may help make the procedure safer.
Watkinsville, GeorgiaAges 18–75 - NCT06613555Recruiting
Eye blood vessel scan study for systemic disease
This study uses an advanced eye scan (OCT-A) to look at tiny blood vessels in the back of the eye. It compares people with systemic blood vessel conditions (like high blood pressure or inflammatory disease) to healthy volunteers, to see if the eye scan can help predict or understand these diseases.
DijonAges 18 years+ - NCT06584825Recruiting
Better vital sign monitoring after major surgery
This trial tests if using a home monitoring device after major surgery can help catch problems early. You or your caregiver would take your vital signs (like heart rate and blood pressure) daily and share them with your care team.
Vancouver, British ColumbiaAges 19 years+ - NCT06312748RecruitingPhase 1
Improving blood vessels in veterans with heart failure
This test is looking at whether certain medications (like statins) can help improve blood vessel health in veterans who have heart failure with preserved pumping function. It may help reduce symptoms and keep you out of the hospital.
Salt Lake City, UtahAges 18 years+ - NCT06062017Recruiting
Potassium, hydration, and heart health in young adults
This study looks at how potassium and hydration affect heart and kidney health in healthy young adults. It may help you understand your own health and contribute to new knowledge about preventing disease.
Auburn, AlabamaAges 18–30 - NCT06087029Recruiting
Improving outcomes in aortic dissection
This study tests a minimally invasive procedure called TEVAR to repair a type B aortic dissection (a tear in the wall of the main artery from your heart). It may help prevent further damage and improve recovery.
Birmingham, AlabamaAges 21 years+ - NCT05641597Recruiting
Free fibula bone transfer study after reconstructive surgery
This study looks at how well a specific reconstructive operation works for a person’s daily function, especially after surgery that replaces part of bone using a healthy bone and blood supply. It may help the team understand what recovery and movement outcomes to expect after this procedure.
DijonAges 18 years+ - NCT05779852Recruiting
Hypnosis to ease new foot amputation wound pain
This trial tests whether auto-hypnosis (a self-guided calming technique) can reduce pain after a toe or multiple toes are removed. It is for adults who are newly after an amputation and have moderate pain soon after the first dressing.
RennesAges 18 years+ - NCT05388682Recruiting
Treating Takayasu disease with lung artery involvement
This trial studies treatment for people with Takayasu arteritis when it affects the lung arteries. It may help reduce problems caused by narrowed or involved lung arteries.
BeijingAges Any age - NCT05433129Recruiting
Test of brain blood-flow control using near-infrared light
This study uses a non-invasive light test on the forehead to measure how your brain regulates its blood flow. It’s meant to help researchers understand brain circulation control in healthy people.
Winnipeg, ManitobaAges 18 years+ - NCT05490238Recruiting
Wrist vs arm access for complex heart procedures
This study compares using the wrist (radial artery) versus a different access site (conventional radial access approach) during complex, larger “bore” heart procedures to open blocked coronary arteries. It aims to see which approach is safer and works better for challenging cases like chronic blockages or heavily calcified arteries.
ArlonAges 18 years+ - NCT05386277Recruiting
Testing safety of an embolectomy catheter used during clot surgery
This study follows patients who are having surgery to remove a blood clot in an artery or vein and where a specific clot-removal catheter (the LeMaitre TufTex Single Lumen) is used. It aims to confirm how well the device works and monitor safety outcomes.
GenkAges 18 years+ - NCT04750876Recruiting
Psychological and physical therapy follow-up after leg amputation
This trial tests whether adding both psychological support and physical therapy check-ins before and after leg amputation improves recovery and rehab planning. It may help patients feel better and regain function during the transition to rehabilitation care.
