Madison, WisconsinAges 20–40 - NCT07019519Recruiting
Gut hormones and blood flow in POTS
This study looks at how gut hormones control blood flow after eating in people with POTS. It may help explain symptoms like dizziness and rapid heartbeat after meals.
CopenhagenAges 18–50 - NCT05400174Recruiting
How blood pressure changes affect thinking and brain flow in Parkinson’s
This study measures how your blood pressure affects thinking skills and how blood flows in the brain in people with Parkinson’s. It may help researchers understand what blood-pressure changes could mean for cognition in Parkinson’s.
San Diego, CaliforniaAges 50 years+ - NCT03773159Recruiting
Testing a blood clot test using whole blood flow
This trial tests a new lab device that measures how well your body forms primary blood clots while blood is kept in flowing conditions. It may help doctors better assess bleeding or clotting tendencies and guide future care.
BesançonAges 18 years+ - NCT05679739Recruiting
Caring for brain after cardiac arrest
This study tests a treatment approach aimed at protecting the brain and supporting better blood flow to the brain after a cardiac arrest. It may help some people who are in a coma right after the event recover more safely or with less brain injury.
SingaporeAges 21–79 - NCT06969547Recruiting
Heart muscle coordination and microvessel function SPECT study
This study uses a special heart scan (SPECT) to look at how well the heart muscle is squeezing and how well the tiny blood vessels in the heart are working. It may help doctors understand why some people have chest pain even when their main arteries are not blocked.
TomskAges 18–75 - NCT07864051Recruiting
Studying blood flow to predict plaque growth in heart arteries
This trial uses special imaging to look at how blood flows through the heart's arteries. It aims to see if certain blood flow patterns can predict where harmful plaque (fatty buildups) may grow, which could help prevent future heart problems.
LondonAges 40 years+ - NCT06878482RecruitingPhase 4
Botulinum toxin injection for severe leg artery disease
This trial tests whether a single injection of botulinum toxin (a muscle-relaxing substance) into the leg can improve blood flow and help heal wounds in people with severe blocked leg arteries who cannot have standard procedures like angioplasty.
Yongin-si, Gyeonggi-doAges 20 years+ - NCT04390035Recruiting
Blood-flow training after ACL surgery for teens
This trial looks at whether a special exercise method that changes blood flow during physical therapy (called BFRT) can improve recovery after ACL reconstruction in teens. It may help strength and rehab progress, but you would need to meet several surgery and safety requirements and attend many PT visits.
Atlanta, GeorgiaAges 12–18 - NCT05250349Recruiting
Ultrasound brain blood flow and thinking in stable heart failure
This trial studies whether a noninvasive ultrasound test of blood flow in the brain, along with memory and thinking questionnaires, can help explain thinking changes in people with stable heart failure. It may help researchers better understand why some people develop cognitive (thinking) difficulties as heart failure progresses.
Krakow, MPAges 18 years+ - NCT05034991Recruiting
Study blood flow in the uterus in endometrial cancer
This study looks at how blood flow in the uterus may relate to endometrial cancer. It may help researchers understand the disease better and guide future care.
Banqiao District, New TaipeiAges 20 years+ - NCT05944146Recruiting
Tests two methods for measuring heart blood flow during surgery
This trial compares a neck ultrasound test (carotid Doppler) with a heart monitoring method (thermodilution) to see if they give consistent blood-flow readings. It may help clinicians measure circulation more reliably in people having heart surgery.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT00437879Recruiting
Ultrasound and MRI scans to track breast cancer response early
This study uses ultrasound and/or MRI scans to see how breast cancer responds early while you start “neoadjuvant” treatment (chemotherapy, with or without radiation before surgery). It may help doctors spot response sooner and better understand which imaging changes match treatment benefit.
Toronto, OntarioAges Any age - NCT05780905RecruitingPhase 4
Semaglutide study for brain blood flow in type 2 diabetes
This trial tests whether semaglutide changes blood flow in the brain and the brain’s “barrier” (how well the brain is protected) in people with type 2 diabetes. It may help researchers understand brain-related effects of diabetes treatment using scans and blood tests.
Seattle, WashingtonAges 40–65 - NCT07754162Recruiting
