A Trial of Alirocumab and Plaque Regression in Peripheral Arterial Disease

Peripheral arterial disease (PAD) is characterized by lower limb arterial obstruction due to atherosclerosis. Magnetic resonance imaging (MRI) methods can accurately quantify atherosclerotic plaque in the superficial femoral artery (SFA) in patients with PAD. Such techniques have demonstrated plaque regression with statin therapy over 1 year. Alirocumab is a PCSK9 inhibitor that effectively reduces LDL cholesterol up to 70% in patients on statins or intolerant to statins. The investigators hypothesize that effective low density lipoprotein (LDL) lowering with Alirocumab 150m subcutaneously (SQ) every 2 weeks will regress atherosclerotic plaque in the SFA in patients with PAD over one year compared to placebo. 54 patients with mild-moderate PAD (ankle brachial index or ABI 0.4-0.9) will be randomized to alirocumab 150 mg SQ every 2 weeks or matching placebo at the University of Virginia (UVA) (n=34) and Northwestern (n=20). The primary endpoint is change in atherosclerotic plaque volume in the superficial femoral artery over the 1 year treatment period. Secondary endpoints include changes in peak calf muscle perfusion after thigh cuff occlusion/hyperemia, 6-minute walk distance, and blood biomarkers (LDL cholesterol, fibrinogen, high sensitivity c-reactive protein (hs-CRP), and lipoprotein(a).

Vessel Deformations and Restenosis After Stenting of the Popliteal Artery

The femoro-popliteal (FP) artery is the most frequently treated vascular segment in patients with symptomatic peripheral artery disease (PAD), for which endovascular therapy became an established treatment option during the last decades. However, loss of primary patency and consecutive clinically driven target lesion revascularization (TLR) limit this procedure. Moreover, in the popliteal artery (PA), evidence about the best treatment strategy to prevent loss of patency and TLR is limited to only a few randomized controlled trials (RCT). Arterial deformations of the PA with its unique anatomical properties during leg flexion might explain the poor technical and clinical outcomes in this segment. Generally, a "leave nothing behind" strategy in the PA is preferred, but cannot be avoided in all cases due to e.g. flow limiting dissections or re-coil after balloon angioplasty. Basically two different self-expandable nitinol-based stent designs are available on the market. An interwoven nitinol and laser-cut nitinol stent. The interwoven nitinol stent has a higher radial force in comparison to the laser-cut stent and reveals higher patency rates in the FP arteries. However, a head-to-head comparison of these stents is missing and it remains unknown in which way different stent designs affect the deformation and hemodynamic behaviors of the PA during knee flexion.

The Role of microRNA-210 in Regulating Oxidative Stress in Patients With PAD

MicroRNA-210 (miR-210) can be a potential therapeutic target of patients with peripheral artery disease (PAD). Recent evidence suggests the role of miR-210 and oxidative stress in the pathophysiology of PAD and its association with mitochondrial function, oxidative metabolism, walking distances and quality of life. The protocol evaluates the mechanisms which miR-210 regulates oxidative stress and provides evidence of potential therapeutic strategies.

Impacts of Mitochondrial-targeted Antioxidant on Peripheral Artery Disease Patients

Title: Impacts of mitochondrial-targeted antioxidant on leg blood flow and skeletal muscle mitochondrial function in peripheral artery disease patients. Peripheral artery disease (PAD) is a common cardiovascular disease, in which narrowed arteries reduce blood flow to the limbs, causing pain, immobility and in some cases amputation or death. PAD patients have shown higher levels of systemic and skeletal muscle inflammation due to the impaired oxygen transfer capacity of these blood vessels. This attenuated oxygen transfer capacity causes hypoxic conditions in the skeletal muscle and results in mitochondrial dysfunction and elevated reactive oxygen species (ROS). These harmful byproducts of cell metabolism are the major cause of intermittent claudication, defined as pain in the legs that results in significant functional limitations. One potential defensive mechanism to these negative consequences may be having higher antioxidant capacity, which would improve blood vessel vasodilatory function, enabling more blood to transfer to the skeletal muscles. Therefore, the purpose of this project is to examine the impact of mitochondrial targeted antioxidant (MitoQ) intake on oxygen transfer capacity of blood vessels, skeletal muscle mitochondrial function, leg function, and claudication in patients with PAD. Blood vessel oxygen transfer capacity in the leg will be assessed in the femoral and popliteal arteries. Skeletal muscle mitochondrial function and ROS levels will be analyzed in human skeletal muscle via near infrared spectroscopy and through blood samples. Leg function will be assessed by walking on a force platform embedded treadmill and claudication times will be assessed with the Gardner maximal walking distance treadmill test.

Adapted Physical Activity in Patients With Lower Limb Peripheral Arterial Disease

The prevalence of peripheral arterial disease is 12.2% in France. Intermittent claudication is the most common symtom of this disease. During physical exercise, such as walking, blood oxygen (O2) requirements increase. The development of atherosclerosis in the lower limbs, causes narrowing of the arteries and limits the increase in blood flow required for muscular effort. Patients then experience muscle pain, the intensity of which gradually increases until it forces them to stop. After stopping, the pain subsides and disappears in less than 10 minutes. The location of the pain (calves and/or thighs and/or buttocks) is related to the location of the ischemia (distal in the calf, proximal in the thigh or buttock, or proximo-distal if several locations). This can have different consequences on the biomechanical parameters of walking and muscle activity. To date, the impact of this localization on physical capacity has never been studied. These limitations are very disabling and impact the quality of life of patients. In addition, poor lower limb performance is associated with higher mortality. Reducing symptomatology and improving functional abilities is therefore a major issue in patients with peripheral arterial disease. This can be achieved through the practice of an Adapted Physical Activity, an essential recommendation in the care of patients with peripheral arterial disease. Our main hypothesis is that the physical activity rehabilitation protocol "Activ'AO" will improve the functional capacities of patients with peripheral arterial disease who have followed the program with the localization of ischemia with a greater consideration than in patients in the group following a "standard" APA protocol. Improvements in functional abilities (such as walking) will lead to improvements in quality of life.
