This research project is designed to see if treatment with the Replexa+ shortwave diathermy device daily for 3 months will improve blood flow in the lower legs and feet of patients diagnosed with peripheral artery disease and peripheral neuropathy.

Shockwave: Disruption for A Better Fit

Recent clinical trial results demonstrate that IVL can increase lumen area by emitting sonic pressure waves, with less inflation pressure as compared to traditional angioplasty balloon dilation and resulting in minimal trauma to the vessel. Therefore, the use of IVL prior to placement of a stent for severely calcified femoral popliteal arteries may be associated with more successful stent implants and better long-term patency, resulting in a decrease in cardiovascular events. The investigator will evaluate the success by defining as lesion stenosis less than 30% and no evidence of Major Adverse Cardiac Event including death or any amputation of the index limb within 30 days of the procedure.

Cardiovascular Risk in Peripheral Artery Disease Patients Undergoing Endovascular Revascularisation

This study will investigate heart-related complications in patients with peripheral arterial disease (PAD) undergoing endovascular revascularization procedures to improve blood flow in the legs. Previous studies have shown that some patients develop silent heart injury after these procedures, even without symptoms, and that this may be associated with worse long-term outcomes. Approximately 500 patients will be included in the study. Blood tests for cardiac biomarkers, including high-sensitivity troponin and NT-proBNP, will be performed before and after the procedure. Participants will also undergo ultrasound examination of the heart to assess heart function, including advanced measures that may detect early or subtle heart damage. In addition, heart rate variability will be measured using a short electrocardiogram recording. Patients will be followed for 30 days and 1 year after the procedure to assess the occurrence of major cardiovascular events, limb-related complications, and death. Additional blood samples will be collected and stored for future analysis of inflammation, oxidative stress, and genetic markers that may help explain the mechanisms associated with heart injury and prognosis in these patients.

Effect of a Hybrid Rehabilitation Program on Walking, Quality of Life & Cardiovascular Risk in People With PAD

Peripheral arterial disease (PAD), a disabling condition, affects 800,000 Canadians. People with PAD suffer from poor quality of life due to leg pain, which makes walking difficult. They also have a high risk of heart disease. In November of 2017, the University of Ottawa Heart Institute (UOHI) launched Canada's first specific walking rehabilitation and cardiovascular risk reduction program dedicated to patients with PAD. An on-site, supervised exercise program to improve walking endurance and quality of life in PAD has been shown to be successful. However many patients are not able to participate in the on-site program due to barriers such as transportation, parking, or other commitments. Recently, a home-based walking program has also been shown to significantly improve walking endurance and quality of life among people with PAD. It was decided that a hybrid program, that has a short on-site program followed by a home-based program may allow more patients to participate and have the highest chance of success. The goal is to develop a new hybrid program for medical care in PAD patients in order to: (a) improve their walking distance, (b) improve their quality of life and (c) improve their cardiovascular risk. As part of this study the investigators will enrol 25 participants with PAD. Participants will be studied at baseline (before their first on-site class) and at 3 month follow up (after their last home program phone call).

Cell Therapy for Lower Limb Ulcers in Patients With Critical Limb Ischemia

Peripheral arterial disease (PAD) can progress to critical limb ischemia (CLI) of the affected lower limb, characterized by pain at rest, ulcerations or gangrene, with a high risk of amputation. In this phase, the best treatment is arterial limb revascularization, but this is not always possible or even effective for promoting pain relief, healing of ulcers or preventing amputations, in addition to the high socioeconomic cost caused by the disease. Recent advances in cell therapy represent a promising supporting alternative for the treatment of PAD in cases where conventional alternatives have run out. Objective: To evaluate the safety and efficacy of cell therapy with expanded autologous mesenchymal stem cells in the treatment of patients with PAD with CLI and chronic arterial ulcers. Methods: An open randomized clinical study will be performed with 2 groups of 20 patients with CLI: in group 1, a fragment of abdominal fat tissue (10g) will be collected to obtain mesenchymal stem cells, which will be expanded and applied using subcutaneous perilesional injection in the affected lower limb, in addition to the application in the form of a personalized curative biological on the wounds. Group 2 will receive conventional treatment with a Hydrogel dressing with essential fatty acids. Periodic clinical evaluations, complementary exams and photographic record will be carried out. The main outcome of effectiveness will be partial or total wound healing. Safety outcomes will be monitored for infections, gangrene, amputations and deaths. Participants will be monitored for 120 days. Major amputation cases will not be included. An independent external evaluator and blind to the groups will evaluate the results. It is an innovative procedure with high impact and financial return for SUS, in view of the high prevalence of the disease and the high socioeconomic impact of the disease when it progresses to limb amputation.

The purpose of this study is to evaluate the effects of Blood Flow Restriction (BFR) training on walking function, health-related quality of life, and safety among adults with Peripheral Arterial Disease (PAD). The main aims of the study are: 1. Evaluate change in walking function among patients with PAD undergoing BFR training. The investigators will assess change in Six-Minute Walk Test (6MWT) distance from baseline to post-intervention and 3-month follow-up to compare functional improvements between the BFR group and the two control groups 2. Assess changes in health-related quality of life among patients with PAD undergoing BFR training. The investigators will use the EuroQol 5-Dimension 5-Level (EQ-5D-5L) scale to evaluate quality-of-life changes from baseline to post-intervention and 3-month follow-up across all study arms 3. Evaluate the safety and feasibility of a supervised BFR training program for patients with PAD. The investigators will compare adverse event (AE) and serious adverse event (SAE) rates across study arms, while also monitoring sessional ratings of perceived exertion (RPE), dyspnea, and claudication pain as indicators of symptom response and exercise tolerance. Feasibility will be assessed through enrollment success, intervention adherence, and retention rates across groups

Study to Image Inflammatory Activity of a Fluorescence Imaging Agent in Excised Human Artery Plaques

Active inflammation plays a key role in causing Coronary Artery Disease (CAD) and Peripheral Arterial Disease (PAD). Since inflammation is so important in how these diseases start, are diagnosed, and treated, being able to see it clearly in each patient could lead to more personalized and effective care - and may help prevent heart attacks. Right now, there's no imaging technology available to clearly see inflammation inside the coronary arteries. The investigators hope to learn how an imaging drug; called LUMISIGHT (Pegulicianine) can help detect inflammation in blood vessels compared with saline. If the investigators find out that LUMISIGHT is active in humans, the investigators might be able to use it for detecting plaque risk in the future.

PROMISE III: Percutaneous Deep Vein Arterialization for the Treatment of Late-Stage Chronic Limb-Threatening Ischemia

A prospective, single-arm, multi-center study designed to gather additional information on the LimFlow System.

Fisetin to Reduce Senescence and Mobility Impairment in PAD

The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with peripheral artery disease (PAD). the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with peripheral artery disease. In exploratory analyses, the investigators will assess whether Fisetin reduces interleukin-6 (IL-6) and novel senescent markers in adipose tissue, muscle, and/or blood.

SMART Exercise for PAD

Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.
