The purpose of this research study is to examine the role oxidants, substances produced in the blood that can damage blood vessel function, may play in blood vessel function in healthy individuals as well as individuals with mental health disorders (posttraumatic stress disorder (PTSD) and/or generalized anxiety disorder (GAD)).
This first-in-human clinical feasibility study will evaluate the safety and performance of the R3 Vascular MAGNITUDE® Bioresorbable Drug-Eluting Scaffold and Delivery System in patients undergoing treatment for peripheral arterial disease severe enough to have significantly reduced the blood supply to their leg. The severe reduction in blood flow causes lifestyle limiting leg pain for these patients, and may lead to amputation of the affected limb due to the loss of tissue in the leg or foot from ulcers or gangrene. The investigational device being studied in this trial is intended to restore blood flow to the affected limb, providing symptomatic relief to the patient and reducing the risk of limb amputation. The scaffold is a type of vascular stent placed within the diseased artery below the knee to improve blood flow. Unlike commercially available metallic stents which are permanently placed within the artery, the MAGNITUDE® Bioresorbable scaffold is made of a polymer material that will completely dissolve away over time, providing the support necessary to the artery while it is healing after the treatment procedure and then slowly disappearing from the artery once that support is no longer needed. The investigational scaffold has been successfully used to treat vascular blockages in the coronary arteries of the heart, but the RESOLV I study will be the first time this device has been used to improve blood flow in the arteries of the lower leg. Patients enrolled in this study may have up to three vascular blockages in their lower leg arteries treated with the MAGNITUDE® Bioresorbable scaffold, and then will be assessed over the course of the following five years to evaluate whether the investigational treatment was successful in safely alleviating their leg pain and other symptoms.
The goal is to compare the results observed in patients that had both an exercise oximetry and a thallium scintigraphy for lower limb claudication
STARDUST is an open-label, two-arm randomized controlled trial, aimed at evaluating the effects of liraglutide on peripheral perfusion, as compared with the aggressive treatment of cardio-metabolic risk factors, in people with type 2 diabetes and peripheral artery disease. The potential benefits for participants in the study include the possibility of improving peripheral perfusion with drugs that have been evaluated as effective in controlling diabetes and safe and protective for cardiovascular health. The primary outcome of the study is the change of peripheral transcutaneous oxygen tension between groups at three and six months. Participants in the study will be followed for 6 months in order to evaluate the effects of liraglutide and the change of other secondary outcomes.
This study is a prospective, multi-center, real world, observational study, which aims at evaluating the safety, efficacy and economic cost of endovascular treatments for endovascular therapies in tosaka III (totally occluded) in-stent restenosis.It is estimated that 300 subjects diagnosed with tosaka III in-stent restenosis and receive endovascular treatments will be enrolled in nine centers from April 2021 to December 2022 nation-widely. All the subjects will be under follow-up for 24 months. There is no restriction on the endovascular techniques. The primary outcomes include clinical-driven freedom from TLR at 24 months.
This study will focus on people with claudication from peripheral arterial disease. The investigators are researching whether a multicomponent therapeutic can increase the production of Nitric Oxide in the blood and whether that leads to an improvement in pain free walking distance and overall physical activity.
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.
A single-arm study to assess the utility of the Pantheris SV catheter in addressing peripheral artery disease in arteries located below the knee. Data will be collected on the percent stenosis pre- and post-atherectomy and then symptoms and adverse events noted at 30 days, 6 months, and 1 year after the procedure.
Taiwan has more chronic kidney disease (CKD) per capita than anywhere in the world, leading to the highest expense of National Health Insurance. By reviewing previous studies, uremic toxins contribute critically to the detrimental effects of CKD on atherosclerotic peripheral artery disease (PAD). When recognized early and managed appropriately, mortality and complications of the participants with CKD and established PAD can be minimized. It is critical to identify novel biomarkers and mediators, which can help identify those with potential poor outcomes and facilitate the discovery/development of novel therapeutics for the patients with CKD and PAD. The OMICs studies support the theory that gut microbiome is a major contributor to adverse cardiovascular outcomes and progression of CKD. However, successful integration of multi-omics approach remains sparse. There is no report on the impact of gut microbiota on the host circulating long non-coding RNAs (lncRNAs) expression signature, other CAD/PAD potential marker, and the potential link between gut microbiota, circulating lncRNA levels changes and CKD/PAD. Additionally, although numerous studies indicated that probiotics or activated charcoal have benefits for CKD patients, few studies evaluated the effect of coadministration of activated charcoal/probiotics on the patients with CKD/PAD. The mechanisms of therapeutic effect on CKD/PAD patients with coadministration of activated charcoal/probiotics involving the cross talk among host, microbiota and metabolites still remain unclear. Thus, in the present study, investigators aim to develop novel diagnostic/prognostic markers and a new treatment with activated bamboo charcoal (ABC)/probiotics for therapeutic opportunities to prevent cardiovascular complications, amputation and death in CKD patients with established PAD. To identify the diagnostic/prognostic markers, the multi-omics (microbolome and metabolome) and lncRNA will be analyzed. The therapeutic impact of activated bamboo charcoal (ABC)/probiotics with optimal formulation, on the renal/endothelial/vascular function, cardiovascular (CV) outcome and mortality in CKD patients with PAD will be also determined to evaluate its therapeutic opportunities.
