Active clinical trials for "Peripheral Arterial Disease"

The purpose of this study is to investigate the prevention of Restenosis following Revascularization of the superficial Femoral Artery (SFA)

The purpose of this study is to compare the Chocolate PTA Balloon to standard Percutaneous Transluminal Angioplasty (PTA) catheters. The investigators will use Optical Coherence Tomography (OCT) and Quantitative Vascular Angiography to evaluate the acute vascular response of vessels treated with the Chocolate Balloon to a standard balloon catheter, with the primary endpoint being luminal gain assessed by OCT lumen volume measurements.

The purpose of the study is to determine associations between fitness status, bacteria in the mouth, and the blood flow to muscle. This study is trying to find out if fitness status impacts the bacteria that are present in the oral microbiome (environment in the mouth) or the ability of the body to send blood to the skeletal muscle. Participants will complete all or some of the following: A mouth swab to assess the bacteria in their mouths. Produce a saliva sample into a tube. Cycle on a bike until you reach maximum effort. Undergo blood draws Wear a 24-hour non-invasive device that monitors blood pressure. Undergo a test to assess blood flow to the muscles measured with an ultrasound. Drink 70mL (1/3 of a cup) of concentrated beetroot juice once

Single-center, observational registry study with a prospective and retrospective arm to evaluate the impact of multidisciplinary CLI teams and protocol on amputation rates, vascular studies, revascularization, in-hospital and long-term outcomes.

Sixty patients with mild-to-moderate PAD (ABI 0.4-0.9) and hypertriglyceridemia (>200 mg/dl) already treated with statins will be imaged at baseline and randomized to Lovaza and placebo for 12 months. MR imaging will be repeated at the end of the 12-month period. We hypothesize that treatment of hypertriglyceridemia in patients with PAD with Lovaza will reduce atherosclerotic plaque volume in the superficial femoral artery (SFA) by 2% over 1 year compared to placebo. Secondary aims will be to show improved plaque characteristics (thickened fibrous cap, reduced lipid-rich necrotic core, improved exercise calf muscle perfusion using first-pass contrast enhanced MRI and improved exercise treadmill performance with Lovaza compared to matching placebo.

Elastic compression stockings are recommended in the treatment venous insufficiency. Degressive compressive stockings have been used for many decades and are characterized by a high pressure applied at the ankle and a decreasing pressure from the ankle to the knee. Progressive compressive stockings were developed to have a maximal pressure at the calf. This concept is based on the calf pump role in the venous return. Patients with PAD (Peripheral Arterial Disease) often suffer from venous insufficiency. But elastic compression stockings are strictly contraindicated for patients with PAD because highest pressures on ankle could slow down the superficial microcirculation. On patients with PAD and venous insufficiency, the progressive compressive stockings could be well indicated. Strongest pressure at the calf should increase the pump effect and the muscle mechanical efficiency during the walk without deleterious effect.

Peripheral Arterial disease is a common condition which causes narrowing of the arteries. The most common symptom that patients with PAD experience is Intermittent Claudication (IC), pain in the lower limb(s) on exertion, which is relieved by rest. IC reduces patients' quality of life (QoL) by limiting their ability to walk and engage in daily activities. Regular exercise and physical activity (PA) are central to the management of PAD and help to improve walking distances and reduce the risks associated with PAD such as heart attack and stroke. However, exercise and PA in this population is often limited due to pain. Investigators have shown that Transcutaneous Electrical Nerve Stimulation (TENS) can help to reduce pain and increase walking distance in patients with PAD. Investigators have also shown that educating patients about their condition and helping them to set goals has the potential to increase PA, and quality of life. This study will examine the feasibility of designing a definitive trial that investigates whether TENS can improve the physical activity of patients with PAD when delivered alone and/or alongside a patient education programme.

The investigators propose a randomized control trial to evaluate long term effects and effectiveness of Moore Balance Brace (MBB) ankle foot orthoses (AFO) in reducing risk of falling in older adults. Primary Endpoints • Characterize the impact of MBB AFO on balance, gait, risk of falling, frailty status, and adverse events Secondary Endpoints • Characterize the Impact of MBB AFO on spontaneous daily physical activities • Characterize the feasibility of the MBB AFO device on patient adherence, acceptability, user-friendliness, and perception of benefit for daily usage

Intermittent claudication afflicts 5% of the US population older than 55 years of age and develops along with hardening of the arteries of the legs. Claudicating patients limp and can only walk very short distances because their legs hurt. This protocol evaluates the mechanisms that may produce the leg dysfunction of claudication and its successful completion can ultimately produce significant new diagnostic and treatment strategies for the care of claudicating patients.

Peripheral arterial disease (PAD) is a significant vascular condition affecting millions of adults. Exercise such as walking is highly effective for reducing PAD symptoms such as claudication (pain with walking) and improving physical function. The trial examines the efficacy of a internet-delivered walking program for patients with PAD. Comparator groups including telephone counselling, the combination of internet-delivered walking program + telephone counseling, or usual care. The primary outcome of interest is maximal walking distance.
