547 Clinical Trials for Various Conditions
The goal of this observational study is to identify which plaque lesions in patients with peripheral arterial disease are impenetrable and to determine which devices minimize vessel wall injury. Patients undergoing intervention will have an MRI scan prior to their planned percutaneous vascular intervention to assess the plaque and predict procedural difficulty. Patients undergoing lower limb amputation due to peripheral arterial disease will have their limbs included into a second arm of the study The limb will undergo an MRI scan to assess the plaque. The investigator will then test two different devices and assess the effects of these devices on the vessel wall.
POWER PAD 2 is a prospective, single-arm, multicenter, non-randomized clinical study designed to demonstrate the safety and effectiveness of the Amplitude Vascular Systems (AVS) Pulse Intravascular Lithotripsy™ (Pulse IVL™) System for treatment of calcified (moderate to severe), stenotic, superficial femoral and popliteal arteries in patients with peripheral arterial disease.
The objective of this trial is to determine if Near-infrared spectroscopy (NIRS) can accurately evaluate the degree of Peripheral Arterial Disease (PAD) during a Provocative Elevation Maneuver of the Lower Extremity (PEMLE) test, as compared to routine clinical assessments.
Many patients with blockages in the arteries in their legs (peripheral arterial disease, "PAD") suffer from pain in their legs when walking. Exercise therapy is known to decrease pain levels as well as increase the distance that patients with PAD can walk. The purpose of this study is to understand whether home exercise using a digital exercise monitoring system (LIVMOR) with provider supervision/ feedback will improve walking distance compared to those undergoing home exercise using the same monitoring system but without provider supervision/ feedback.
Peripheral arterial disease (PAD) is a highly prevalent and costly condition. Intermittent claudication (IC), defined as ischemic leg pain that occurs with walking, results in functional impairment, reduced daily physical activity, and a lower quality of life. Although the mechanisms contributing to functional impairment are not fully delineated, current evidence suggests that the uncoupling of skeletal muscle cellular metabolism from tissue perfusion may be responsible for exercise intolerance. We have previously shown increases in plasma inorganic nitrite, via oral nitrate, produced clinically significant increases exercise performance in patients with PAD+IC. The hypothesis of this proposal is in patients with PAD+IC, 3-6 days of oral dietary nitrate consumption (in the form of concentrated beetroot juice) will produce a greater tissue perfusion, oxygen delivery, and enhanced muscle metabolism in comparison to placebo. This will translate into an increase in physical performance in both muscle specific plantar flexion exercise and treadmill measures of pain free ambulation. In order to test this hypothesis, we will recruit 10 patients PAD+IC in a randomized, double-blind, placebo controlled, cross over design.
The purpose of this study is to understand how the drug rivaroxaban improves symptoms associated with peripheral artery disease.
Peripheral arterial disease (PAD) is a manifestation of systemic atherosclerotic cardiovascular disease (ASCVD) and is associated with increase cardiovascular risk. PAD impairs quality of life due to symptoms of claudication, pain at rest or risk of limb loss. All major societies recognize the importance of LDL reduction in patients with PAD. Statin therapy improves cardiovascular end-points in patients with PAD and have been shown to improve symptoms of lower extremity intermittent claudication (pain free walking time), 6-minute walking time, ankle-brachial index (ABI), and endothelial function, while decreasing markers of atherosclerosis. This study aims to demonstrate that in patients with PAD on stable maximal tolerated lipid lowering regimen with a statin, further reduction of LDL with the pro protein converts subtilisin/kexin type 9 (PCSK-9) inhibitor Evolocumab, improves functional status (pain free walking time in particular, but also maximal walking time), lower extremity arterial perfusion and endothelial function (brachial endothelial reactivity).
The primary goal of this clinical trial is to evaluate whether a community-based structured exercise therapy (CB-SET) intervention, which could be accessible and easily disseminated, adds benefit to peripheral artery disease (PAD) patients undergoing revascularization (REVASC) to improve their function and cardiovascular health.
The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON™ Atherectomy System, within the initial launch phase of the product in the market.
The study objectives of this projects are to examine the hypothesis that the sympathetic and blood pressure responses to exercise will be attenuated during and after heat exposure in patients with peripheral artery disease, via altering the sensitivity of the muscle afferent receptors.
The INTERCEDE randomized trial will establish whether six-months of intermittent pneumatic compression combined with walking exercise improves walking endurance at six-month follow-up, compared to walking exercise + sham compression therapy, in people with lower extremity peripheral artery disease (PAD). The INTERCEDE trial will also determine whether intermittent pneumatic compression therapy improves walking endurance at 6-month follow-up, compared to a sham compression therapy. The trial will also determine whether benefits of intermittent pneumatic compression persist after intermittent pneumatic compression treatment is completed.
NICE is a randomized clinical trial that will examine the effects of nicotinamide riboside (NR) both with and without resveratrol to test whether, among people with PAD, NR significantly improves walking performance more than placebo and whether NR combined with resveratrol significantly improves walking performance more than placebo. If findings support the hypotheses, results will be used to design a large, definitive randomized clinical. The study will randomize 90 participants with PAD to one of the following three groups: NR + resveratrol, NR + placebo, or placebo + placebo.
By doing this study, researchers hope to learn about the feasibility of using a mobile application to help overweight or obese adults with PAD increase their walking distance and lose weight.
HI-PAD is a placebo controlled double-blind randomized pilot clinical trial to determine whether VM202 may improve walking ability in people with lower extremity peripheral artery disease (PAD).

The purpose of this study is to learn about the impact of text messaging on physical activity in persons with risk factors for peripheral arterial disease (PAD).
The purpose of this study is to understand the effects that a three month lifestyle-based mobile health (mHealth) peripheral artery disease (PAD) prevention program will have on improving physical activity, fitness, important PAD risk factors and quality of life (QOL) in patients with PAD. By testing a novel mHealth intervention focused on lifestyle modification, this trial will address a critical evidence gap in the care of PAD patients. PAD patients are not eligible for cardiac rehabilitation and therefore struggle with unhealthy lifestyles, and these patients currently have no lifestyle-based care strategies to help them. The results of this study have the potential to lead to new sustainable and resource-efficient, lifestyle-based preventive care strategies for patients with stable PAD.
