Active clinical trials for "Peripheral Arterial Disease"

This study will test whether, among patients undergoing surgery for peripheral artery disease (PAD), the addition of an online multimedia patient education video to the current education regimen will improve PAD knowledge, activation, and self-care engagement. The study will randomize 150 participants to one of 2 groups: current education regimen vs. current education regiment with video. The primary outcome is stage of self-care engagement. Secondary outcomes are PAD knowledge, self-efficacy, and activation. A subset of participants will also be randomly selected to participate in semi-structured interviews. Study duration for participants is 6 months.

This randomized controlled study aimed to determine the effect of foot reflexology on pain and ankle brachial index level in patients with peripheral artery disease

to compare the safety and efficacy of spinal anesthesia using Hyperbaric Prilocaine 2% versus Hyperbaric Bupivacaine 0.5% for patients with peripheral vascular disease and cardiac dysfunction.

Patients with peripheral arterial disease (PAD) often have walking impairment due to insufficient oxygen supply to skeletal muscle. The investigator's pilot study in PAD patients has shown that endothelial function and walking distance improve with regular static muscle stretching. Therefore, the purpose of this study is to determine whether prescriptive muscle stretching improves muscle oxygenation and walking ability in PAD patients. This is a single-blinded study in 40 patients with stable symptomatic PAD. Patients assigned to the stretch group will use ankle splints (both legs) to perform static muscle stretching for 4 weeks (ankle dorsiflexion applied 30 min/d, 5 days/wk). Patients assigned to the control group will also wear the ankle splints daily but without invoking any dorsiflexion, i.e., without stretching. Measurements will consist of ankle-brachial index (ABI) at rest and post-exercise, skeletal muscle oxygenation (evaluated with near-infrared spectroscopy (NIRS)), and 6 minute walk test (6MWT), performed at baseline and after 4 weeks of stretching (or control splint placement). In addition, NIRS will be used to evaluate muscle oxygenation while patients are wearing the splint device in order to quantitatively prescribe the angle of dorsiflexion that provides optimum stretch and deoxygenation of the calf muscles without causing pain. Primary outcomes include increased muscle oxygenation during exercise and walking distance after 4 weeks of static muscle stretching. Results from this study will be used to support funding applications for a larger efficacy trial.

The purpose of this research study is to investigate and determine the effects of static magnetic fields produced by a small magnet on peripheral pulses and skin blood flow.

The purpose of this study is to determine if walking biobehavioral intervention improves physical activity after dysvascular lower limb amputation.

The aim of this study is to investigate the effect of different treatment strategies on mitochondrial function and to correlate in-vitro results to findings from in-vivo measurements of mitochondrial function. The authors hypothesize that interventional revascularization and therefore the restoration of blood and oxygen supply is more relevant to mitochondrial function compared to the effect of exercise training.

The goal of this clinical trial is to determine the effect of elevated plasma ceramides on peripheral vascular function. Subjects will consume a high fat meal consisting of long chain fatty acids (to increase plasma ceramides) or medium chain fatty acids (control). Subjects' vascular function will be assessed with laser Doppler flowmetry to measure their artery function and with the CytoCam device to assess their peripheral microvascular endothelial function.

This study will focus on people with claudication from peripheral arterial disease. The investigators are researching whether a multicomponent therapeutic can increase the production of Nitric Oxide in the blood and whether that leads to an improvement in pain free walking distance and overall physical activity.

The purpose of this research study is to examine the effect of various forms of exercise training on blood vessel function in healthy individuals as well as individuals with mental health disorders (posttraumatic stress disorder (PTSD) and/or generalized anxiety disorder (GAD)).
