Filter by:The purpose of this first-in-man study is to evaluate the safety and performance of the Dynalink®-E everolimus eluting peripheral stent system for the treatment of patients with atherosclerotic de novo or restenotic native superficial femoral and proximal popliteal lesions. Abbott Vascular is ceasing data analysis of the STRIDES Clinical Trial after 2 years. The decision to discontinue the study is not related to any safety concern. The rationale for this proposal is based on the following considerations: The performance of DYNALINK-E from STRIDES shows no device- or procedure-related deaths and no stent fractures, and the rate of additional revascularizations has been stable since approximately 14 months after the procedure. Evaluations of the bare metal nitinol DYNALINK and ABSOLUTE stents in the clinical literature show low rates of death, reintervention and stent fracture, which are consistent with STRIDES and demonstrate the safety of the nitinol stent platform of the DYNALINK-E. Long-term animal studies show no concerns with the drug or polymer coating of DYNALINK-E - everolimus tissue concentration drops below the quantifiable limit by approximately 17 months after implant, and vascular response to the coating is normal with widely patent lumens and struts incorporated into vessel tissue. The safety and performance of the DYNALINK-E has been substantiated by its clinical and pre-clinical data, and by the clinical data of similar products. Given the demonstrated mechanical integrity of the stent along with the evidence of a healthy long-term vascular response, there is a reasonable expectation of continued low event rates.
Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

Peripheral arterial disease (PAD) is the most common manifestation of systemic atherosclerosis and accounts for significant morbidity and mortality among end-stage renal disease (ESRD) patients. However, few studies have identified the prevalence and clinical impact of PAD in this specific population. Objectives: To perform a single-blinded parallel, controlled trial to examine the effect of cilostazol treatment on plasma VEGF levels, tissue factors , inflammatory markers (such as IL-6, hsCRP) levels, oxidative stress markers in ESRD patients with PAD Material and methods Fourty HD patients on maintenance HD for > 3months were enrolled in this prospective, single-blinded, randomized study. These patients were randomly allocated into 2 arms. After baseline assessment, patients in the treatment arm received 12 weeks of added on therapy with cilostazol 100mg/day. Blood pressure, heart rate, oxidative stress (malonyldialdehyde, protein carbonyl and ADMA), inflammatory markers (hsCRP, IL-6) and plasma, VEGF and tissue factors levels were measured before and after treatment.
This is a double blind crossover study designed to compare two different gadolinium products given at the same dose to patients undergoing MRA assessment of lower legs for the evaluation of peripheral steno-occlusive disease.
This study will treat patients with such severe lower leg ischemia or vascular compromise that they have pain at rest. The goal is to compare treatment of the patient's painful disorder by injecting cells into the calf of the leg and testing for circulatory improvement. A treatment will given at random to two groups and will be injection into the calf muscle with ALD-301 (specially processed stem and progenitor cells) from the patient's own bone marrow, or with cells processed by more routine that minimally purifies the cells. The study goal is to see if the ALD-301 cells are more effective in generating new small blood vessels to improve the circulation to the affected leg.
It is hypothesized that patients with vascular disease are undertreated for modifiable risk factors, leading to increased morbidity and mortality in this population. The objective of this study is to develop a comprehensive database that will demonstrate the current adequacy of risk factor management in this high risk population, and that will provide needed guidance for future treatment options.
Diabetes is a major cause of peripheral vascular disease(PVD) and is associated with male hypogonadism. Diabetes and PVD are both associated with arterial stiffness and intima -media thickness which are also related to severity of the clinical syndrome of PVD. Artificially induced hypogonadism results in increasing arterial stiffness whilst testosterone is known to improve risk factors for vascular disease and act as a vasodilator. The purpose of this pilot study is to assess the effect of testosterone treatment on PVD arterial stiffness and intima-media thickness in men with type 2 diabetes and hypogonadism,
Severe peripheral vascular disease of the legs causes narrowing of the blood vessels in the legs, which keeps the blood from flowing adequately through these vessels. This study is designed to examine whether treating patients with their own previously collected blood stem cells will improve blood flow in the most severely affected leg. Blood stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream.
Background: Percutaneous transluminal angioplasty (PTA) has been popularized as a simple, effective and cheap treatment achieving 50-70% symptomatic patency rates in patients with peripheral occlusive disease.. However, the fact remains that the indication for performing PTA are still more based on opinions than on scientific data. The purpose of the trial was to randomize patients primarily referred for intermittent claudication into two groups: One group was offered conservative treatment; the other group was offered conservative treatment combined with PTA. Primary outcome: The patient quality of life. Secondary outcome:Pain-free walking distance; pain-score; death; amputation; changes in relevant biomarkers
