Active clinical trials for "Peripheral Arterial Disease"

By doing this study, researchers hope to learn about the feasibility of using a mobile application to help overweight or obese adults with PAD increase their walking distance and lose weight.

The purpose of the artery preparation concept is to perform regular longitudinal micro-incisions on the inner side of the artery ("scoring") and therefore promote a regular expansion of atheroma by balloon inflation.

In patients with critical limb ischemia (CLI) and foot ulcers wound healing is an important goal which can normally only be achieved after sufficient treatment of the underlying ischemia (revascularization either by an operation, e. g. bypass, or a catheter intervention). After successful revascularization everything should be done to improve wound healing because this regularly takes weeks up to several months. One possibility to speed up healing could be treatment with the VADOplex device which delivers an automatic intermittent painless compression of the sole of the foot thereby increasing perfusion of the leg. This system can be easily operated by patients themselves and at home. Our goal is to prove that the VADOPlex system accelerates healing up and improves quality of life.

The objective of IMPACT (Investigation of Motivational Interviewing and Prevention Consults to Achieve Cardiovascular Targets) is to determine the best management strategy for patients undergoing cardiovascular intervention. IMPACT is a prospective randomized trial that will enroll 400 patients post-cardiovascular intervention. The study will compare different cardiovascular prevention strategies: (1) usual care, (2) cardiovascular prevention consult, and (3) cardiovascular prevention consult with a behavioral intervention program over a 6-month period. The trial hypothesis is that for patients undergoing a cardiovascular intervention, a prevention consult and behavioral intervention is superior to usual care in reducing cardiovascular risk. The primary endpoint will be non-HDL cholesterol. Secondary endpoints include other lipid values, metabolic risk, smoking cessation, physical activity, nutritional status, medication adherence and quality of life. IMPACT is scheduled to begin enrollment in the June of 2012.

Peripheral arterial disease (PAD) causes reduced blood flow to the lower limb(s) due to stenosis or occlusion in the supplying arteries. Symptoms of PAD range from ischemic rest pain and/or ischemic ulcers/gangrene (critical limb ischemia), putting the extremity at risk of amputation, to exercise-induced pain (intermittent claudication), limiting the patients daily activities. Invasive treatments are often indicated to prevent amputations and to alleviate symptoms. More than two thirds of these procedures are presently performed with endovascular techniques (i.e. percutaneous transluminal angioplasty, PTA with or without stent implantation). In coronary artery disease, stents eluting anti-proliferative drugs (drug eluting stents, DES) reduce restenosis and improve clinical results for the majority of patients. Drug eluting balloons (DEB) are a promising alternative, but there is still little evidence that DES or DEB technology improve clinical outcome in PAD. However, promising results utilizing these new technologies in PAD have been reported in a few studies. In this trial, we test the hypothesis that drug eluting (DE) technology is superior to conventional endovascular treatment (no-DE) in terms of important clinical outcomes, when applied on infrainguinal (femoropopliteal and/or infrapopliteal) obstructive vascular lesions. The trial consists of 2 separate parallel studies, SWEDEPAD 1 and SWEDEPAD 2, each defined by the severity of peripheral arterial disease. Patients with critical limb ischemia are allocated to SWEDEPAD 1 and patients with intermittent claudication are allocated to SWEDEPAD 2.

If patients need to undergo bypass surgery, either an autologous vein can be used as bypass or, if there are no suitable veins are available, a prosthetic graft can be implanted. Varicose veins normally are judged not to be suitable as bypass. The ProVena vein support, made from polyester, is considered to strengthen varicose veins so that they they become suitable as bypass. Thereby, the advantages of an autologous bypass and the stability of polyester material can be combined. Patients that take part in the trial recieve an autologus bypass with a varicose vein, coated with ProVena. They are followed up at 3 and 6 months after implantation of a ProVena-coated bypass via duplex-sonography to assess the graft patency.

To determine whether fruit juice might reverse endothelial dysfunction and whether this reversibility has a prognosis value

The study is designed to determine whether vorapaxar, when added to the existing standard of care (SOC) for preventing heart attack and stroke (eg, aspirin, clopidogrel) in participants with a known history of atherosclerosis, will yield additional benefit over the existing standard of care without vorapaxar in preventing heart attack and stroke. The study is also designed to assess risk of bleeding with vorapaxar added to the standard of care versus the standard of care alone.

The purpose of the study is to determine the response to aspirin (ASA) and Clopidogrel in patients with peripheral arterial occlusive disease (PAOD) requiring interventional procedures and to investigate if patients with "resistance" to ASA or Clopidogrel have an unfavourable outcome during long-term follow-up

Peripheral artery disease (PAD) affects mainly elderly patients. The ankle brachial index (ABI) and ultrasound imaging are the standard diagnostic tools in PAD diagnostic and severity estimation. Measurements are generally performed by a vascular physician. However, access to medical specialist is becoming increasingly difficult with long waiting times while the aging of the population increases, while most of these patients are seen by the general practitioner. To date, there is a lot of data in the literature on the value of using various ambulatory devices in the diagnosis and severity estimation of PAD but studied one by one. The investigators propose to compare the measurements made by a series of simple non-invasive ambulatory tools with the measurements performed by the vascular specialist. The investigators wish to demonstrate that a series of simple and economical tools, available to paramedical health professionals can diagnose PAD and evaluate ts severity the reducing the direct and indirect associated costs.
