Kogarah, New South WalesAges birth–130 years - NCT06912984Recruiting
How exercise affects blood vessels as we age
This study looks at how exercise changes blood vessels differently in older women and men. You'll be randomly assigned to either an exercise program or a no-exercise control group for a few months, and researchers will measure your blood vessel health before and after.
Aurora, ColoradoAges 18 years+ - NCT03717792Recruiting
Check how doctors follow up vascular liver disease
This study focuses on people who have vascular liver disease and aims to evaluate follow-up care and non-invasive ways to assess it. It may help improve how safely and accurately doctors monitor your liver without invasive procedures.
BonnAges 18–100 - NCT06230731Recruiting
Oxygen levels in colon blood vessels during colonoscopy
This study measures oxygen levels in the colon during a routine colonoscopy to understand how blood flow differs between people with vascular lesions (abnormal blood vessels) and those with a healthy colon. It may help doctors better diagnose and treat these conditions.
Chicago, IllinoisAges 18–89 - NCT05481723RecruitingPhase 3
Lung ultrasound to guide fluid and blood pressure during surgery
This Phase 3 study tests whether using a lung ultrasound scan during surgery can better guide blood pressure and fluid needs. It may help stabilize patients during long operations and reduce complications related to poor circulation or fluid balance.
AmiensAges 18 years+ - NCT06325800Recruiting
Heart and blood vessel health registry
This study collects information from people at risk for heart disease, stroke, or kidney problems to better understand how to prevent these conditions. If you join, you'll be helping doctors learn more about how to keep blood vessels healthy.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT07720570Enrolling by invitation
Bleomycin electrosclerotherapy for slow-flow vascular malformations
This trial tests a treatment called bleomycin electrosclerotherapy for people with slow-flow vascular malformations (abnormal blood vessels that do not flow quickly). The goal is to see if this treatment works well and is safe for these conditions.
Copenhagen, Capital Region of DenmarkAges 2 years+ - NCT03527420Recruiting
Study of body fat, blood vessels, and DNA changes
This study looks at how having a high body mass index affects blood vessel function and changes in DNA. It may help researchers understand why weight-related health risks happen and how bariatric surgery could help.
Chicago, IllinoisAges 18–50 - NCT03732612Recruiting
Studies inflammation markers around upcoming vascular surgery
This study looks at signs of “inflammation” (your body’s immune response) in people who are scheduled for vascular surgery. It may help researchers understand what’s happening in blood vessel disease and improve future care.
Gothenburg, VastragotalandAges 18 years+ - NCT03806283Recruiting
Study how pregnancy blood vessels change in late pregnancy
This study looks at how blood vessels adapt during late pregnancy, especially around the time of a C-section. Your participation may help researchers understand normal pregnancy changes and how they differ in certain complications.
