Real-World Safety Analysis of Paclitaxel Devices Used for the Treatment of Peripheral Arterial Disease

Treatment with paclitaxel-based endovascular devices (PED) has become a common treatment option for patients with peripheral artery disease (PAD) involving the femoral-popliteal artery. However, an aggregate level meta-analysis identified an association between the use of PED and increased all-cause mortality at both two and five-year follow-up intervals, though there are significant limitations of these analyses. Exploration of real-world data has been suggested as a means to further investigate the safety of PED. The current study explores the association of PED and mortality in real-world data using U.S. commercial claims from the FAIR Health data warehouse.

MyPADMGT Support of Out-Patients With Peripheral Arterial Disease

The investigators have developed an online program to help people with peripheral arterial disease (PAD) in their extremities to better self-manage their condition. Some earlier testing has been done and the investigators now wish to try this system with participants who have this blood vessel disease as well as high blood pressure. Investigators are hoping to help these participants to achieve healthier lifestyles and improve their quality of life through education, monitoring and continuing support. A similar online desk-top version with over 30 participants has been tested at St. Michael's Hospital in Toronto. The investigators propose to test this newer mobile system with 210 outpatient participants from Hamilton General Hospital. Data collected will be analyzed following the (12 months for each participant) study, along with data recorded during clinical visits at baseline and twelve months for each participant. The objective is to evaluate changes to participant health and determine whether the health self-management process has been successful in improving participant lifestyles and quality of life, when compared to usual care.

The Impact of Diabetes on REvascularization

The presence of foot symptoms at rest or tissue necrosis in patients with peripheral artery disease is a medical urgency and represents a state of critical limb ischemia (CLI) where the risk of amputation, in the absence of revascularization, is high. No trial conducted to date in peripheral revascularization has determined the effect of diabetes on mechanism of revascularization failure. Therefore, this trial represents a unique opportunity to investigate the mechanisms by which diabetes affects surgical and endovascular revascularization procedures with the long-term goal of improving outcomes in CLI.

Influence of Rivaroxaban for Intermittent Claudication and Exercise Tolerance in Patients With Symptomatic PAD

The aim of the conducted research is to evaluate the protective effect of rivaroxaban (trade name of the Xarelto medicinal product), administered together with acetylsalicylic acid (ASA), in comparison with the effectiveness of using ASA alone, in relation to the distance of claudication and exercise tolerance in patients with PAD over a period of 3 months. At present, COMPASS results show that rivaroxaban vascular dose (2.5 mg twice daily) in combination with ASA (75-100 mg once daily) provides more effective cardiovascular protection (defined as cardiovascular death, vascular, myocardial infarction and stroke) compared to ASA alone. So far, however, no scientific studies have been carried out into account the effect of the drug on the progress of PAD and exercise tolerance in patients.

Angiotensin-(1-7) in Peripheral Arterial Disease

Peripheral arterial disease (PAD) affects over 8 million individuals in the United States alone. This is a form of atherosclerosis in which plaques preferentially build up inside the arteries of the legs to limit blood flow. These patients are at high risk for heart attack and stroke, with at least half dying from coronary artery disease. Our understanding of the causes of PAD remains incomplete. The renin-angiotensin hormone system is one mechanism known to contribute to atherosclerosis. Pharmacologic blockade of the hormone angiotensin II is beneficial in forms of atherosclerosis, including peripheral arterial disease, to improve blood vessel damage and functional outcomes. These therapies also increase circulating levels of angiotensin-(1-7), a hormone that dilates blood vessels. Angiotensin-(1-7) improves blood vessel function and reduces inflammation to protect against atherosclerosis in animal models; however, there are no clinical data in patients with atherosclerosis. The overall goal of this project is to examine the cardiovascular effects of angiotensin-(1-7) in PAD.

Dietary Nitrate Supplementation and Thermoregulation

This is a double-blinded, randomized, crossover design study to assess the effects of dietary nitrate supplementation (beetroot juice) on peripheral artery disease (PAD) patients (ages 50-85) diagnosed with Fontaine stage I or II PAD (as determined by vascular surgeon, Dr. Pipinos at UNMC). Exclusion criteria include: 1) experience severe claudication (leg pain) at rest or tissue loss due to PAD (Fontaine stage III and IV), 2) have limited walking capacity due to conditions other than PAD, 3) are already supplementing with a form of dietary nitrate, or 4) have an allergy to beetroot juice. Subjects will be required to visit the lab 3 times and will be randomized to receive either the supplement or the placebo for the 2nd and 3rd visits. There will be a washout period of 14 days between the 2nd and 3rd visits. Visit 1 will take approximately 2 hours and the 2nd/3rd visits will take approximately 1.5 hours. Total experimentation period will last approximately 15 days. Visit 1 will consist of non-invasive baseline testing including assessment of endothelial function (flow-mediated dilation by ultrasound imaging), maximal walking capacity (Gardner treadmill protocol), leg function (near-infrared spectroscopy, time to onset claudication, blood flow to lower extremities), and body core temperature (rectal thermometer). Visits 2 and 3 will require consumption of either the supplement or placebo. The same tests from the baseline measurements will be performed for visits 2 and 3. There will be a recommended fourth visit, albeit not required, to review study results.

Start: September 2018

Exercise Rehabilitation in Veterans With PAD

Peripheral artery disease (PAD) results in blockages of arteries (blood vessels) and decreased blood flow to the legs. This may cause difficulty or pain with walking or other activities that use leg muscles. Exercise may help improve blood flow in the legs and improve the ability to walk. This research project will be conducted patients with PAD that require revascularization. The goal is to examine the effects of 3 months of exercise rehabilitation or neuromuscular stimulation on leg blood flow, physical function, quality of life and general health.
