This study tests a new tool called the FastWire System that helps doctors safely cross completely blocked arteries in the leg. The goal is to restore blood flow and avoid serious problems like amputation. About 65 people with severe leg pain or non-healing wounds will take part. …

This study compares taking two blood thinners (clopidogrel and aspirin) for 1 month versus 6 months after a leg artery procedure. The goal is to see if the longer treatment keeps the treated artery open longer and prevents serious events like heart attack or stroke without causin…

This study tests whether computer alerts can help doctors prescribe cholesterol-lowering drugs to people with peripheral artery disease (PAD) who aren't taking them. About 400 adults with PAD will be randomly assigned to have their doctors receive an alert or not. The goal is to …

This registry is following 240 people who receive the GORE VIABAHN VBX stent graft to treat blocked or damaged arteries in the abdomen, pelvis, or limbs. Researchers are tracking how well the device works and any serious side effects over time. The goal is to see if the stent gra…

This study tests whether using carbon dioxide gas instead of standard iodinated contrast dye during leg artery procedures can prevent serious kidney problems. About 1,960 people with peripheral artery disease who are at higher risk for kidney injury will be randomly assigned to r…

This study is testing a device called Laser Speckle Contrast Imaging (LSCI) that uses a laser to measure blood flow in the leg. The goal is to see if it can help doctors monitor blood flow before, during, and after surgery to restore circulation. The study will enroll 30 people s…

This pilot study tests whether a 12-week home-based exercise program using a small pedal exerciser can help people with moderate-to-severe peripheral artery disease (PAD) walk farther and feel better. Twelve adults with severe PAD will be randomly assigned to either the home exer…

This early-phase trial tests whether a single dose of Vumerity (diroximel fumarate) can improve blood vessel function and walking ability in 20 people aged 50-75 with peripheral artery disease (PAD). Participants will receive either Vumerity or a placebo, and researchers will mea…

This pilot study tests whether fisetin, a natural compound found in strawberries, can reduce aging cells and improve walking ability in 34 people aged 50+ with peripheral artery disease (PAD). Participants will receive either fisetin or a placebo for 4 months. The main goal is to…

This study tests whether shining a specific red light on the legs each day before a walking session can help people with peripheral artery disease (PAD) walk farther. PAD causes leg pain and difficulty walking due to poor blood flow. The trial will involve 32 adults aged 50 and o…

This study tests whether adding nitrate-rich beetroot juice to exercise helps people with peripheral artery disease (PAD) walk farther and with less pain. 210 adults aged 50+ with PAD will be assigned to either supervised treadmill or home walking, plus either beetroot juice or a…

This study tests a surgical technique called targeted muscle reinnervation (TMR) to prevent phantom limb pain and stump pain after a leg amputation. About 200 adults having a leg amputation due to blood vessel disease will be randomly assigned to receive either TMR or standard ne…

This study is a large registry that collects safety and performance data on Terumo Aortic knitted and woven grafts and cardiovascular patches used in standard clinical practice. It will include about 2,000 patients who need these devices to repair or bypass damaged blood vessels,…

This study surveys doctors who use the Liberant system to remove fresh blood clots from leg arteries and veins. About 50 patients aged 22 or older will be treated within 72 hours of their procedure. The goal is to confirm the device is safe and works as intended.

This study looks at how exercise training impacts blood vessel function in people with PTSD or generalized anxiety disorder, compared to healthy individuals. Researchers want to understand if harmful substances called oxidants play a role in blood vessel damage. The study involve…

This study is collecting medical information and blood/urine samples from 9,500 people with various heart and blood vessel conditions, plus healthy volunteers, over 20 years. The goal is to find better ways to diagnose heart disease and predict how patients will do in the future.…

This study looks at how different exercise programs affect blood vessel function in people with PTSD or generalized anxiety disorder, compared to healthy individuals. Researchers will measure changes in arm and leg blood vessel dilation after 10 weeks of strength training. The go…

This study is gathering information from 50 Canadians with Peripheral Artery Disease (PAD) who are treated in heart clinics and can still walk. Researchers want to measure inflammation levels and physical abilities to better understand the condition. The results will help doctors…

This study uses MRI scans to look at plaque buildup in leg arteries of people with peripheral arterial disease. Researchers want to see which plaques are hard to cross with a guidewire and which devices cause the least damage to the vessel wall. The study includes patients underg…

This study will use tiny probes called microdialysis to measure chemicals related to blood flow, inflammation, and antibiotics right inside the amputation stump after surgery. Researchers will compare results between diabetic and non-diabetic patients to understand why some stump…

This study installs a 'black box' recording system in hybrid operating rooms to capture and analyze errors during vascular procedures. Researchers will study how teamwork, leadership, and the environment affect surgical performance and patient safety. The goal is to identify high…

This study looks at how different exercise programs affect blood vessel function in people with PTSD or generalized anxiety disorder. Researchers will compare moderate versus high intensity exercise in 360 participants. The goal is to see if exercise can improve vascular health, …

This study is collecting information from up to 10,000 people who receive BALT medical devices for conditions like brain aneurysms, stroke, and blocked arteries. Researchers will track how well the devices work and if any safety issues arise during routine care. The goal is to ga…

This study is testing whether a new imaging device called MIMOSA Pro can measure oxygen levels in leg tissue as accurately as standard tests like ankle-brachial index or Doppler ultrasound. Researchers will compare the device's readings to those from traditional methods in 60 adu…
