Filter by:Patients with peripheral artery disease have decreased blood flow to exercising muscle causing pain. This decreased blood flow to the muscle affects the level of acylcarnitines which in turn decreases the level of carnitine. Carnitine allows muscles to function properly. This study will test the safety and efficacy of Propionyl-L-Carnitine taken in combination with a monitored exercise training program.
The purpose of this study is to evaluate the change in Walking capacity after an intake of caffeine. The study design is cross-over and follow-up of 80 patients with leg pain caused by narrowing of their leg arteries, Peripheral Vascular Disease (PAD), stage II. Half of all will be revascularised, follow up will be after 3 months. It is hypothesized that caffeine (6mg/kg) can be a cheap, safe drug before walking exercise. Primary endpoint is maximum walking distance (MWD), treadmill-testing,(constant load, 0%,2m/h). Secondary endpoints are pain free walking distance (PWD), maximum muscle strength, endurance, reaction speed, balance, cognitive function, health related quality of life (SF-36).
To obtain additional data on safety and efficacy of the Express stent implantation in the treatment of stenosed or occlusive atherosclerotic disease (de novo or restenotic lesions) in the iliac arteries (common or external).
This trial was designed to challenge the wide held view that polytetrafluoroethylene (PTFE) performs better than Dacron for above knee femoropopliteal bypass.
To investigate in patients suffering from intermittent claudication due to Fontaine stage II PAD whether a 24-week treatment by SL650472 OD on top of clopidogrel may result in an improvement of walking capacity, by comparing three doses of SL650472 to placebo, and to calibrate such effect versus cilostazol
263 patients with peripheral atherosclerosis were examined to evaluate the activity of the platelets during the standard treatment, including aspirin. A subgroup of 43 received 600 mg of clopidogrel 2 h before platelet reactivity analysis. The main hypothesis is that high platelet activity at the beginning of the study is associated with a higher risk of atherothrombosis. Follow up time is 5 years.
This trial will test the hypothesis that inflammation and insulin resistance contribute to reduced walking distance in subjects with intermittent claudication by impairing vascular reactivity and skeletal muscle metabolic function.
The whole study is divided in 4 parallel protocols. The first protocol estimates the reliability of the technique through test-retest recordings. The second protocol aims to prove that exercise Tcpo2 is efficient to estimate the benefit of proximal revascularisation on proximal and distal ischemia in patients suffering stage two lower extremity arterial disease. The third protocol aims at estimating with exercise tcpo2 the eventual apparison of proximal ischemia after aorto-bi-femoral bypasses. The last protocol is a transversal study of patients with aorto-bi-femoral bypasses aiming to analyse the presence of proximal and distal symptoms and ischemia. The hypothesis for protocol 2 is that TcpO2 at exercise is significantly improved after surgery at the aortic and primary iliac artery. The hypothesis for protocols 3 and 4 relates on the hypothesis that a significant number of patients benefiting aorto-bi-femoral bypass suffer isolated proximal pain/ischemia after surgery. Amendement to the project has been recently validated to study the neurologic and bone complication of chronic vascular ischemia
This study is a comparison of different medical devices for infragenual dilatation.
The purposes of this pilot project are to (a) determine changes in calf muscle blood flow and energy supply resulting from calf muscle exercise, and (b) to determine changes in these variables resulting from exercise training (walking and calf muscle exercise). This is a pilot study to prepare for a larger project in the future. Exercise and exercise training should increase blood flow and energy supply to the calf muscles.
