Filter by:The planned study is a Randomized Controlled Monocentric Trial, which will provide evidence on whether early angiography in PTA readiness ("immediate treatment," within 48h) has advantages over the "standard of care", i.e., an elective procedure ("elective PTA") in terms of clinical endpoints such as wound healing and infection according to WiFI classification, amputation rate, "major adverse limb events" (MALE=amputation, reintervention of the vessel, death), but also systemic complications such as "major adverse cardiac and cerebrovascular events" (MACE=myocardial infarction, stroke, death, restenosis, severe cardiac and cerebrovascular complications). Furthermore, the impact of PTA on the local wound microbiome remains unclear. Altered microbiome composition in ulcers can lead to severe local and systemic infections and complications, including major amputations. Nevertheless, the specific significance of the wound microbiome composition in chronic ischemic ulcers in type 2 diabetes and the impact of PTA on the wound microbiome in type 2 diabetes is unclear. The exact timing for treating pAVD by revascularization in DFS after initial diagnosis is unknown and has yet to be fully understood.
This study is an investigator-initiated, prospective, single-center, 1:1 randomized pilot study. The trial evaluates the safety and efficacy of intravascular lithotripsy in comparison to standard lesion preparation using standard and/or high-pressure balloon angioplasty in patients with femoropopliteal artery disease. All patients will receive subsequent Supera stent implantation at the operator's discretion. Additional standard nitinol bare metal stent (BMS), drug-eluting stent or covered stent implantation is at the operator's discretion. Patients will be stratified for total occlusions.
The objective of the study is to evaluate the feasibility of the CSGS sensor to differentiate tissues involved in Peripheral Artery Disease (PAD).
The purpose of this project is to evaluate the effectiveness of a virtual diabetes group visits on patients with type 2 diabetes mellitus (T2DM).
The aim of the study will be to evaluate shear stress and blood flow parameters in lower limb arteries during arm cycle ergometer exercise in participants with peripheral artery disease. Twenty patients participants with peripheral artery disease and claudication symptoms will be recruited. Participants will perform 3 experimental sessions in random order. Iarm-cranking (15 sets of two minutes exercise), warm water foot immersion, and control. During the interventions, blood pressure and heart rate will be assessed every 6 minutes. Measurements of arterial diameter, blood flow, anterograde and retrograde shear stress of the femoral artery will be evaluated using a two-dimensional ultrasound device with spectral Doppler.
Sixty elderly patients from both sexes with PAD, stage II fontaine will participate in this study. Their ages will be from 40-90 years old. They will be selected from kasr el ainy (faculty of medicine), Cairo University, Giza, Egypt. The patients will be randomly assigned into two equal groups: Group (A): 30 patients will receive transcutaneous electrical nerve stimulation (TENS) for 45 minutes per session applied on calf muscle, combined with treadmill three days per week for twelve weeks in addition to the routine medical treatment. Group (B): 30 patients will receive treadmill training for 45 minutes per session, three days per week for twelve weeks in addition to the routine medical treatment
Peripheral arterial disease (PAD) is a condition where the blood vessels in the legs get blocked. It affects one out of every five adults over the age of 65. As it is the main cause of amputations, the NHS performs over 20,000 operations every year to prevent them. People with PAD benefit from tablets to thin their blood as this improves outcomes after surgery and prevents heart attacks and strokes. The main tablets for this purpose are aspirin and clopidogrel. These work in most people, but up to a third of patients do not get any benefit from them, as their bodies cannot process them. We call this resistance to therapy (RT).Because blood thinning is particularly important after operations people with RT may be at higher risk of their operation failing leading to amputation and/or problems such as heart attacks and strokes. Testing for RT has not traditionally been performed because it requires complex laboratory procedures. Recent development in technology now means that bedside tests are available for RT. We will use a simple beside test for RT in patients with severe PAD. We will use this test to see how many of these patients have RT and whether this affects their risk of complications after an operation. If we find that RT does affect outcomes for patients with PAD, the information obtained will be used to plan future research to determine if changing blood thinning therapy in people with CR improves their outcomes after surgery.
Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.

This clinical trial aims to analyze the effects of concurrent vs aerobic training on glycemic control, ABI, functional capacity and disease-specific QOL among patients with Type-II DM-associated PAD at baseline & after 12 weeks of intervention. The main questions it aims to answer are: 1. Is concurrent training more effective than aerobic training in improving glycemic control among patients with Type-II DM-associated PAD? 2. Is concurrent training more effective than aerobic training in improving ABI among patients with Type-II DM-associated PAD? 3. Is concurrent training more effective than aerobic training in enhancing functional capacity among patients with Type-II DM-associated PAD? 4. Is concurrent training more effective than aerobic training in improving QOL among patients with Type-II DM-associated PAD? Signed informed consent will be taken before participation. For exercise training, Both will perform Warm up for 10 - 12 minutes, followed by 30 - 60 minutes of training protocol and then Cool down exercises for 10 - 12 minutes. Group A will perform concurrent training, whereas Group B will perform aerobic training.
