Traditional aerobic training and muscle resistance ('strength') training have been shown to be effective for improving functional and health-related quality of life (HRQoL) outcomes in peripheral arterial disease (PAD). However, the transfer of the current resistance exercise modes proposed to other activities of daily living (ADLs) is questionable. Moderate intensity functional training (MIFT) has emerged with the aim of achieving cardiovascular and neuromuscular adaptations simultaneously with functional exercises typical of ADLs. The effect of MIFT in patients with PAD is not yet known. Our purpose is to verify the influence of the combination of intermittent treadmill walking exercise with MIFT compared with intermittent treadmill walking exercise on functional capacity, HRQoL, biochemical and hemodynamic parameters in patients with PAD.
The overarching objective of this study is to improve fall prevention efforts in community-dwelling older adults with peripheral artery disease (PAD) to reduce falls. To accomplish this, the investigators will conduct a feasibility study and pilot the addition of a balance exercise component to existing supervised exercise therapy (SET) programs for PAD. This intervention may be an effective way to help older adults with PAD self-manage their leg pain and walking impairments as well as fall risk. The long-term goal of this research is to reduce morbidity and mortality associated with falls in older adults with symptomatic PAD through the development and evaluation of a balance intervention component implemented within existing exercise programs. Findings from this research may also be translated to the implementation of disease management programs for other chronic conditions associated with fall risk. The rationale for this research is to determine improve disease-specific, comprehensive and fall prevention strategies for older adults with PAD.
This study aims to evaluate whether remote ischemic preconditioning (RIPC) daily for 28 days reduces the symptoms of intermittent claudication in patients with peripheral artery disease (PAD). The study evaluates the effect of RIPC on patients' total walking distance (TWC), initial claudication distance (ICD), and time to relief of claudication (TRC). In addition, the trial investigates the effect of RIPC on different arterial functional characteristics and low molecular weight metabolites in serum and affected skeletal muscle.
This is a BlueDop Vascular Expert System (BVE) Post-Market Clinical Follow-Up (PMCF) study. The primary objective of the study is to assess the clinical applicability and diagnostic accuracy of the BVE device in subjects who require an arterial duplex test due to suspected peripheral arterial disease (PAD).
The study aims to further demonstrate the safety and effectiveness of the FemoSeal™ VCS in achieving hemostasis following percutaneous endovascular procedures performed via the common femoral artery (CFA) access site. This study is conducted in real-world subjects according to the FemoSeal™ VCS instruction for use (IFU), as part of the study device post-market clinical follow up surveillance plan and prospective clinical evidence collection.
The individual restrictions of daily life for patients with PAD are more important than statistical facts for mortality and morbidity. Intermittent claudication causes a progressive reduction of the pain-free walking distance (PWD) as an expression of a worsening PAD. This decrease in physical capability results in a decline of mental health and relevantly reduces the patients' quality of life (QoL). Supervised exercise therapy (SET) is a cornerstone in the conservative management of intermittent claudication and extends the PWD. Even though SET is easy to practice and highly cost effective, the adherence to perform SET on a regular base is rather low. The underuse of exercise can be partly explained by the lack of institutional resources, but also by both patients' and physicians' lack of interest in exercise. Mobile health (mHealth) technologies increase the incentives and provide digital support for patients with PAD on several treatment levels. They might lead to a higher adherence to exercise training and offer new scopes in patient-centered healthcare, but so far studies show opposite results. Because app stores are flooded with health and fitness apps, specific support tools are highly desired by patients with PAD and PAD-specific solutions are missing so far. Based on this background, the investigators developed a smartphone app named TrackPAD to provide PAD-specific support for SET. The TrackPAD pilot study was designed as a 2-armed randomized controlled trial and included patients with diagnosed and symptomatic PAD. Patients were randomized by the Center for Clinical Studies in Essen using the TENALEA software into 2 groups. The control group included participants with standard care and no further mobile intervention. The intervention group included participants with standard care and additional mHealth-based self-tracking of their physical activity using trackPAD.
Peripheral arterial disease (PAD) in the lower extremity is the third leading cause of atherosclerotic cardiovascular morbidity. Endovascular treatment has become the principal surgical strategy in femoro-popliteal lesions. Stent placement induces significant changes in the arterial geometry and thereby in the hemodynamic environment. Visualization of local blood flow patterns (around stents) is challenging, but clinically relevant. Blood flow has a significant influence on the development of atherosclerosis and therefore stent patency. In vivo blood flow characterization might enable the recognition, prediction and explanation of (in-stent) restenosis. This study will therefore aim to investigate the feasibility of a novel ultrasound technique (echoPIV) to quantify spatiotemporal blood flow near stented femoral artery lesions. Furthermore, the blood flow information obtained during the echoPIV measurements will be used as patient-specific boundary conditions in a computational fluid dynamics (CFD) simulation. The tested hypothesis is that blood flow quantification using echoPIV is feasible in and around stents in the femoral artery and that it will improve CFD simulations.
A randomised controlled trial evaluating the feasibility and acceptability of a 12 week lower body blood flow restricted resistance exercise programme for people with peripheral arterial disease.
The hypothesis is that oral supplementation of L-carnosine will inhibit PHDs, increase HIF1-translocation and angiogenesis and thus improve the functioning of lower extremities in PAD patients. Primary Aim: 1. Compare the effect of carnosine and placebo supplementation on the 6MWT in PAD patients with and without claudication. Secondary Aim: 1. Determine whether carnosine supplementation improves the pain-free treadmill walking ability of the subjects supplemented with carnosine compared to placebo. 2. Compare the levels of carnosine, VEGF, HIF-1α, and PHDs activity in the skeletal muscle before and after placebo and carnosine supplementation. 3. Compare the levels of EPCs (CD34+/CD133+), inflammatory markers (serum amyloid A, hsCRP) and thrombotic markers (fibrinogen, homocysteine) as cardiovascular risk markers in these subjects. 4. Explore the effects of race and gender on VEG, carnosine, and HIF-1α levels in both groups.
