Active clinical trials for "Peripheral Arterial Disease"

Diagnosis of vascular involvement in diabetic foot disease remains challenging. Differential diagnosis between pure neuropathic or neuro-ischemic diabetic foot requires a combination of clinical examination, medical history and ankle-brachial index (ABI) measurement, which is considered the "gold standard" non-invasive modality for limb ischemia diagnosis. However, in diabetic patients with suspected arterial ischemia resulting in tissue loss (critical limb ischemia; CLI), false negative ABI results are frequent due to Monckeberg medial sclerosis producing incompressible vessels, while clinical signs are subjective and not accurate in posing definite diagnosis of CLI. The investigators conducted a proof of concept study of the feasibility of microwave radiometry thermometry for non-invasive diagnosis of CLI in diabetic patients with tissue loss.

The overarching objective of this study is to improve fall prevention efforts in community-dwelling older adults with peripheral artery disease (PAD) to reduce falls. To accomplish this, the investigators will conduct a feasibility study and pilot the addition of a balance exercise component to existing supervised exercise therapy (SET) programs for PAD. This intervention may be an effective way to help older adults with PAD self-manage their leg pain and walking impairments as well as fall risk. The long-term goal of this research is to reduce morbidity and mortality associated with falls in older adults with symptomatic PAD through the development and evaluation of a balance intervention component implemented within existing exercise programs. Findings from this research may also be translated to the implementation of disease management programs for other chronic conditions associated with fall risk. The rationale for this research is to determine improve disease-specific, comprehensive and fall prevention strategies for older adults with PAD.

More than 2 million patients in North America are treated with warfarin - a "blood thinner" - to prevent blood clots in arteries or veins. The treatment has to be monitored with a blood test and the dose changed accordingly every 1-4 weeks. One third of the patients have very stable results and hardly ever have to change the dose. The investigators wish to show that the level of control of the treatment with warfarin in these very stable patients is not worse with 12-weekly testing. A pilot study the investigators performed indicated that 12-weekly testing would be safe but this has to be confirmed in a large study. One third of patients taking warfarin have not had any changes in the dose for the past 6 months or longer. These patients will be asked about participation in the study. They will be randomized to testing and dosing every 4 or 12 weeks. Each patient is in the study until it ends, which will be minimum 1 year and can be up to about 4 years. The study is designed to show that 12-weekly testing does not significantly increase the risk for major bleeding or blood clots. The results would be important for a large number of patients. An increase of the interval between blood tests from 4 to 12 weeks would reduce the burden for these patients on life-long treatment considerably.

This study is an efficacy evaluation of Dotarem®-enhanced magnetic resonance angiography (MRA) compared to Gadovist®-enhanced MRA in the diagnosis of clinically significant abdominal or lower limb arterial diseases.

The purpose of this study is to evaluate the safety and efficacy of the Minnow Medical GRST Peripheral Catheter System in the treatment of new lesions in the superficial femoral artery or the popliteal artery.

To assess the clinical efficacy and to simultaneously explore the underlying molecular mechanisms of the beneficial effects of flavanol-rich cocoa on vascular function diabetic patients with peripheral artery occlusive diseases (PAOD) of the lower extremities will be investigated.

This trial aims to evaluate if hyperbaric oxygen treatment (HBO) given postoperatively is effective in reducing healing time and wound complications after lower extremity bypass surgery in patients with diabetes. Hypothesis: Postoperative HBO treatment is effective in reducing complications in patients with diabetes undergoing peripheral vascular surgery

The purpose of this study was to test the hypothesis that the long-term use of highly (>98%) purified EPA, in addition to HMG-CoA reductase inhibitor (statin), would be more effective than statin alone in preventing cardiovascular events in Japanese patients with hypercholesterolemia.

The purpose of this study is to apply local heat to the legs, thighs and buttocks of patients with peripheral arterial disease and use PET/CT imaging with an injectable stable radiotracer to study direct measurement of blood flow in the legs pre and post heat treatment.

The research study is designed to assess the technical feasibility and safety of percutaneous administration of vonapanitase to the superficial femoral or popliteal artery in patients with PAD.
