Filter by:The primary aim of the study is to determine the effect of a community-based walking exercise program with detailed training, monitoring, and coaching (TMC) exercise components enhanced by community-based participatory research (CBPR) practices (TMC+) on the primary outcome of peak walking time (PWT) in patients with peripheral artery disease (PAD).
To study the safety and performance of the Shockwave Medical Lithoplasty System in subjects to demonstrate that the Shockwave device can safely and effectively deliver localized shockwave energy for balloon dilatation of calcified, stenotic, infrainguinal peripheral arteries.
The purpose of this study is to collect acute confirmatory data to evaluate technical success and acute safety of the EverFlex™ self-expanding peripheral stent with Entrust™ delivery system.
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
This study aims to demonstrate if remote ischaemic preconditioning (RIPC) may confer renal protection in patients undergoing peripheral angioplasty. Patients will be randomised to receive RIPC and biomarkers for renal injury will be analysed post procedure to determine if any protective benefit was obtained.
Peripheral arterial disease (PAD) causes reduced blood flow to the lower limb(s) due to stenosis or occlusion in the supplying arteries. Symptoms of PAD range from ischemic rest pain and/or ischemic ulcers/gangrene (critical limb ischemia), putting the extremity at risk of amputation, to exercise-induced pain (intermittent claudication), limiting the patients daily activities. Invasive treatments are often indicated to prevent amputations and to alleviate symptoms. More than two thirds of these procedures are presently performed with endovascular techniques (i.e. percutaneous transluminal angioplasty, PTA with or without stent implantation). In coronary artery disease, stents eluting anti-proliferative drugs (drug eluting stents, DES) reduce restenosis and improve clinical results for the majority of patients. Drug eluting balloons (DEB) are a promising alternative, but there is still little evidence that DES or DEB technology improve clinical outcome in PAD. However, promising results utilizing these new technologies in PAD have been reported in a few studies. In this trial, we test the hypothesis that drug eluting (DE) technology is superior to conventional endovascular treatment (no-DE) in terms of important clinical outcomes, when applied on infrainguinal (femoropopliteal and/or infrapopliteal) obstructive vascular lesions. The trial consists of 2 separate parallel studies, SWEDEPAD 1 and SWEDEPAD 2, each defined by the severity of peripheral arterial disease. Patients with critical limb ischemia are allocated to SWEDEPAD 1 and patients with intermittent claudication are allocated to SWEDEPAD 2.
This study is intended to collect safety and effectiveness data on the Cook Micronized Small Intestinal Submucosa (SIS)
The study is intended to evaluate the safety and feasibility of using the Intact Vascular (Innovasc) Tack-It Endovascular Dissection Repair System (Tack Intravascular Staple System) in patients with vascular flaps in the infrainguinal due post-angioplasty dissection.
The registry will enroll patients with claudication or critical limb ischemia and angiographically significant lesion(s) in arteries of the lower extremity. Subjects will be treated with the Lutonix® Drug Coated Balloon Catheter for approved indications according to the current country-specific Instructions for Use (IFU) and followed clinically for 1 year.
Lower extremity peripheral arterial disease (LEPAD) is a highly prevalent chronic disease. Cardiovascular mortality of LEPAD patients at five years ranges between 18 to 30%. LEPAD is primarily caused by atherosclerosis that induces an inadequate blood flow to meet the tissues demand due to the narrowing of the arteries. An aggravation of the arterial lesions in LEPAD patients induces a worsening of patients' symptoms and a severe limitation of their walking capacity, contributing to an impairment of their quality of life. Despite maintaining a sufficient walking activity is essential for these patients, LEPAD patients lower their physical activity, which worsen the disease and potentially contribute to increase the risk of cardiovascular events and deaths. In a recent study in LEPAD patients, we showed, from a one hour GPS recording, a high variability of the patients' walking capacity (i.e., walking distances between two stops induced by lower limbs pain). Results suggested that in most patients previous stop duration before each walk was a predictor parameter of this walking variability. Whether there is an optimal or minimal recovery time influencing the walking capacity in LEPAD patients has never been studied. This study is a prospective, cross-sectional study in exercise pathophysiology. The main goal is to determine, following a walk that induces ischemia, the influence of the recovery duration on the subsequent walking performance in LEPAD patients. Secondary goals are : 1. To determine the nature of the relationship between the recovery duration and subsequent walking performance. 2. To study the relationship between exercise ischemia, pain evolution and previous recovery duration. 3. To determine whether the experimental procedure influence the determination of an optimal of minimal recovery duration. 4. To study the influence of recovery duration on walking capacity from community-based measurement.
