Active clinical trials for "Peripheral Vascular Diseases"

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.

Does tomato extract improve blood vessel function in healthy people and people with cardiovascular disease? Atherosclerosis ('furring' of the arteries) affects the functioning of blood vessels, narrowing and eventually blocking them, causing conditions like heart attack and stroke. The Mediterranean diet, which is rich in tomatoes and tomato-based products, has been shown to be associated with a reduced risk of blood vessel damage. In this double blind, placebo-controlled randomised study, the investigators will investigate whether a food supplement containing a standardised extract of tomato improves blood vessel function in both healthy people (aged 40-80), and people with a history of cardiovascular disease. The food supplement is on sale to the public, and the investigators are testing the standard dose. Approximately 72 people will take part at the Clinical Pharmacology Unit at the ACCI Building, Cambridge University Hospitals NHS Trust. After they have passed screening tests, participants will be allocated by chance to receive either the tomato extract product (Ateronon), or a matching placebo (a dummy capsule with no active ingredients), which they will take once a day for 8 weeks. At the beginning and end of the treatment period, the investigators will test blood vessel stiffness using an ECG machine and external probe. The investigators will also measure forearm blood flow, which involves infusing 3 separate agents that affect how the lining of the blood vessel wall works, and helps to assess whether this is affected by the study treatment. Blood tests will also be used to look at how the food supplement is working and its effects on cholesterol and markers of inflammation. Including the screening period, and a follow-up telephone call two weeks after the end of treatment, participants will be in the study for 14 weeks.

The purpose of this study is to determine the long-term effects of statins, atorvastatin, upon Nitric Oxide, as an endothelial function assessment, and C-Reactive Protein, an inflammatory marker, levels in patients with Peripheral Arterial Disease. These long-term biological pleiotropic effects of statins will offer information on the role of endothelial function and systemic inflammation in the etiopathogenesis of PAD.

This Clinical Trial is being conducted to study how patients with peripheral arterial disease (a condition in which the blood vessels of the extremities are affected) respond to a dietary regimen of flaxseed. The purpose of the study is to examine whether or not dietary flaxseed have any effect on improving symptoms of cardiovascular disease. Additionally, the effects of dietary flaxseed on exercise tolerance will be assessed.

This is a single site, open registration, dietary proof of concept, food substance study designed to explore the health benefits associated with daily pulse consumption in individuals with peripheral arterial disease. The investigators hypothesis that a diet containing at least one serving of pulse crops (dried beans, peas, lentil, chickpeas) per day provides flavonoid compounds that improve cardiovascular health by increasing the levels of serum adiponectin is based on evidence from the literature that indicates flavonoids present in these foods are capable of improving arterial stiffness and reducing hypercholesterolemia.
