Recreational Team Handball Programme for Patients With Peripheral Arterial Disease

This randomized controlled trial (RCT) aims to evaluate the physical and physiological demands, the feasibility and the health, physical fitness and disease-specific outcomes of a progressive recreational team handball-based programme in patients with lower extremity peripheral arterial disease and intermittent claudication. The primary outcomes will be changes in functional capacity, assessed by the 6-minute walk test. Participants will be randomized to either a 24-week progressive team handball-based intervention or a usual care control group, with assessments performed at baseline, 12 weeks, and 24 weeks post intervention to evaluate health, physical fitness, and disease- specific outcomes.

Magnetic Resonance Angiography for Peripheral Arterial Disease (PAD)

The purpose of this study is to compare the difference between two magnetic resonance imaging (MRI) techniques for visualizing arteries. The study hypothesizes that one method that relies upon imaging flowing blood in the pelvic and leg arteries will not be as accurate or efficient as injecting a safe imaging agent to change the appearance of the blood on the MRI. Both methods will be compared with Digital Subtraction Angiography (DSA).

Amplitude Vascular Systems (AVS) Lithotripsy POWER PAD 2 Trial

POWER PAD 2 is a prospective, single-arm, multicenter, non-randomized clinical study designed to demonstrate the safety and effectiveness of the Amplitude Vascular Systems (AVS) Pulse Intravascular Lithotripsy™ (Pulse IVL™) System for treatment of calcified (moderate to severe), stenotic, superficial femoral and popliteal arteries in patients with peripheral arterial disease.

Expression of GLP1 Receptor on Peripheral Blood Mononuclear Cells in Advanced Peripheral Artery Disease: Paving the Way for GLP1R Agonists Treatment in Chronic Limb Threatening Ischemia

The goal of this observational study is to learn whether activation of the GLP-1 receptor could represent a therapeutic target by characterizing its expression and associated inflammatory mechanisms in patients with peripheral artery disease, according to disease severity, in adults with symptomatic lower-limb peripheral arterial disease. The main questions it aims to answer are: * Is the level of GLP-1 receptor (GLP1R) expression on peripheral blood mononuclear cells (PBMC) different between patients with intermittent claudication (ischemia of effort) and those with chronic limb-threatening ischemia? * Is GLP1R expression associated with inflammatory and oxidative profiles of PBMC? * Can GLP-1 receptor agonists reverse inflammatory and oxidative alterations induced by plasma from patients with peripheral artery disease in endothelial cell cultures? * Are there specific plasma proteomic signatures associated with GLP1R overexpression? Researchers will compare patients with intermittent claudication to patients with chronic limb-threatening ischemia to see if disease severity is associated with differences in GLP1R expression, PBMC inflammatory/oxidative phenotype, and plasma proteomic profiles. Participants will: * Provide an additional blood sample (15 mL) collected during a routine, clinically indicated blood draw * Have PBMC isolated for measurement of GLP1R expression and assessment of inflammatory and oxidative markers * Have plasma analyzed for proteomic profiling and used in in-vitro endothelial cell experiments Participation ends after completion of the blood sampling, and no additional procedures beyond standard clinical care are required.

A Non-significant Risk Clinical Study: Changes in Perfusion After Therapeutic Ultrasound in Patients With PAD

All evaluable subjects will receive VibratoSleeve therapeutic ultrasound (TUS) treatments. The device will be programmed to deliver TUS at a pre-determined level. Three different acoustic intensity levels will be tested during the first three treatment visits (one at each visit day). The most effective treatment that is comfortable to a subject will be prescribed for the remaining treatment sessions. Treatment time will be 90 minutes per session, one session per day. Thirty treatment sessions will be performed over a 45-day period. Subjects will appear for on-site follow-up visits at 1-, 3-, and 6-months following subject's last (30th) treatment session.
