Filter by: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 Zilver PTX Registry Study is a prospective, non-randomized, open-label, multicenter single-arm study enrolling patients in Europe, Asia, and North America with de novo or restenotic (including in-stent restenosis) lesions of the above-the-knee femoropopliteal artery (SFA). The primary endpoint of the study is event-free survival (EFS) at 6 months.
The investigators propose that once daily administration of PF-00489791, a phosphodiesterase inhibitor, will reduce vasospasm and improve symptoms and signs associated with Primary and Secondary Raynaud's Phenomenon.
The Registry involves the collection of information for research and educational purposes only on the use of AngioJet in the peripheral vascular system.
Primary Objective: To investigate the value of the Edinburgh Claudication Questionnaire (ECQ) against the ankle-brachial index (ABI) in Canadian patients mainly followed in general practice, with documented acute coronary syndrome (ACS)/ischemic stroke (IS)/transient ischemic attack (TIA) and who are not known to have peripheral arterial disease (PAD) at the time of enrolment. Secondary Objective: To collect data on the prevalence of PAD in this population as measured by ABI.
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.
Peripheral arterial disease is a common condition in older adults involving poor arterial circulation in the legs leading to leg pain and debility. The body's own circulating blood vessel stem cells may help to improve circulation. This study will test whether treatment with the drug granulocyte macrophage colony stimulating factor (GM-CSF) will improve symptoms and signs of peripheral arterial disease over placebo after four weeks of therapy. As well this study will examine whether improvements in blood vessel function can be observed. Finally, we will measure blood vessel function and stem cell levels in order to determine whether they can help to predict whether patients wither peripheral arterial disease will suffer further cardiovascular complications.
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 assess the safety and the immediate effect of the VascuActive device on patients with peripheral vascular disease and limb ischemia.
The purpose of this study is to determine plasma levels of paclitaxel and catheter tolerability subsequent to treating patients with peripheral arterial occlusive disease (PAOD) with paclitaxel-coated balloon catheters.
