Intermittent vascular claudication

This study is testing a device that uses sound waves to break up calcium buildup in the leg arteries of people with peripheral artery disease. The goal is to improve blood flow, reduce pain, and help people walk better. About 50 participants will be followed for one year to see i…

This study compares a new balloon coated with everolimus to standard paclitaxel-coated balloons for opening blocked leg arteries in people with peripheral artery disease. About 410 participants will be randomly assigned to one of the two balloons. The goal is to see if the new ba…

This trial tests whether a 12-week supervised treadmill exercise program can improve blood flow and walking distance in people with peripheral artery disease (PAD). It also explores whether adding nitrate-rich beetroot juice helps those who don't respond to exercise alone. Two hu…

This study is collecting information from 5,000 people with peripheral vascular disease who are being treated with Boston Scientific drug-eluting devices in everyday medical practice. The goal is to see how well these devices work and how safe they are in a wide range of patients…

This study tests a new, pain-free exercise program for people with peripheral artery disease (PAD), which causes leg pain when walking. Researchers will compare it to standard painful exercise over 3 months in 100 adults aged 40 and older. The goal is to see if the pain-free prog…

This study tests whether metformin, a standard diabetes drug, can improve walking ability in people with peripheral artery disease (PAD) who experience leg pain during activity. Researchers will give 200 Veterans either metformin or a placebo for several months and measure change…

This study tests whether combining the DASH diet (a heart-healthy eating plan) with a home-based walking program can improve walking ability and quality of life in people with peripheral artery disease (PAD). PAD causes leg pain during walking due to narrowed arteries. The study …

This study tests whether drinking beetroot juice daily for 4 months can improve walking distance in people with peripheral artery disease (PAD). Researchers will compare a beetroot juice group to a placebo group in 210 adults aged 50 and older. The main goal is to see if beetroot…

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 a community-based exercise program can improve walking ability and heart health in people with peripheral artery disease who have recently had a procedure to open blocked leg arteries. Researchers will enroll 30 participants and measure how long they can …

This study tests whether a TENS pain-relief device, combined with video coaching sessions from a physiotherapist, can help people with leg pain from peripheral artery disease (PAD) become more active. Forty-eight participants will either get the TENS device plus coaching or usual…

This study tracks 98 people with peripheral artery disease who had a stent placed in their iliac artery. Researchers want to see which patients later develop serious limb complications, like needing another procedure or amputation. They will also check if frailty plays a role. Th…

This study looks at immune cells called macrophages in the arteries of people with heart disease or poor leg circulation. Researchers will use imaging and blood tests to see how these cells are activated. The goal is to better understand the disease, not to test a new treatment. …

This study is testing whether shining a red light (670 nm) on the calf muscle for 5 minutes can increase blood flow in people with peripheral artery disease (PAD). Forty adults with PAD will receive the light treatment and an ultrasound contrast injection to measure blood flow. T…

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 looks at whether the natural pulsation of the spinal cord is linked to pain and disability in people with lumbar spinal stenosis (a narrowing of the spine). Researchers will measure pain, function, and MRI images in 100 adults aged 18-85. The goal is to better understa…

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 compares standard 2D X-ray imaging with a 3D imaging technique called OCT during leg artery procedures. About 166 adults with blocked leg arteries will be randomly assigned to one of two groups. The goal is to see if OCT helps doctors place stents and inflate balloons …

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…
