Active clinical trials for "Peripheral Arterial Disease"

Induction of autologous angiogenesis in patients with critical limb ischemia using platelet lysate.

Japanese post market clinical study of the Zilver Flex device.

Japanese post market clinical study of the Zilver PTX device.

The purpose of this study is to test if dexamethasone, an anti-inflammatory medication approved by the US Food and Drug Administration (FDA), can be injected safely into the tissue around the blood vessel wall at the time of an angioplasty or atherectomy.

The purpose of the study is to evaluate the safety and efficacy of laser atherectomy with balloon angioplasty compared to balloon angioplasty alone in the treatment of above the knee peripheral artery in-stent restenosis.

The purpose of this study is to find out if aldehyde dehydrogenase bright (ALDHbr) cells taken from a patient's bone marrow can be placed safely, via intramuscular injections, into their affected calf and lower thigh muscles and improve blood flow and/or peak walking time in patients experiencing pain associated with blocked blood vessels in the leg.

A primary therapeutic goal for patients with intermittent claudication (IC) is to regain lost physical function through exercise rehabilitation. Supervised exercise programmes can markedly improve walking capacity, but these are resource intensive, National Health Service provision is limited, and patients cite accessing services as a barrier to participation. Increasing walking activity via a structured education programme might be a pragmatic solution for improving walking capacity, health and wellbeing in patients with IC; however, further research is needed to substantiate this. Hence, the aim of this project is to develop a pragmatic education programme to increase walking in these patients and to collect data on its feasibility to inform the development of a definitive trial investigating clinical and cost effectiveness. Focus groups will be conducted to inform the development of the education programme. Programme components will be theoretically-underpinned and evidence-based. The development of the programme will be an iterative process involving pilot work, feedback, evaluation, and revision. The programme will then be assessed in a randomised controlled pilot study with 6-week follow-up (n=30). We will assess the feasibility of the intervention and obtain preliminary data of its impact on important outcomes (daily steps/physical activity, walking capacity, quality of life, illness perceptions).

The purpose of this study is to determine whether the peripheral balloon dilatation catheter (trade name: Iris) is safe an effective in PTA procedure.

Peripheral arterial disease (PAD) is a pathological condition limiting, resulting from a narrowing or occlusion of the artery diameter due to aneurysms, inflammation, atherosclerosis and thromboembolic events. One of the main risk factors for the development of DAP is diabetes mellitus due to its relation to the process of atherogenesis. Thus, the objective of this study is to evaluate the effects of three treatment modalities for PAD on the blood flow velocity. It is a crossover study. Fifteen women with diabetes receive three types of treatment, the order defined according draw: high voltage electrical stimulation, shortwave diathermy and kinesiotherapy. The blood flow of the lower limb will be assessed by Doppler ultrasound. The hypothesis of this study is that physical therapy resources increase the circulation of the lower limb.

Cardiovascular disease remain one of the leading causes of death in Australia, accounting for 47637 (36%) of deaths in 2004. Peripheral arterial disease (PAD) is a category of cardiovascular disease, characterised by intermittent claudication. This is defined as walking induced pain, cramping, aching, tiredness or heaviness in one or both legs that does not go away with continued walking and is relieved with rest. It is estimated that between 5-10% of individuals aged over 50 years suffer from claudication. The primary and most effective treatment for these patients is focused on improving walking ability and functional status. Current research has shown that approximately 30% of patients improve with exercise, while 30% continue to deteriorate and the rest show no change. The changes produced at a biochemical and cellular level due to exercise are unknown. To help better understand this, our study will assess the entire range of proteins expressed before and after exercise in the skeletal muscle tissue of patients with intermittent claudication. This will help to identifying key proteins that have a role in improving patient symptoms and outcome.
