Filter by:The maximal walking distance (MWD) performed on treadmill (TT) remains the gold standard in estimating the walking capacity of patients suffering from peripheral arterial disease (PAD) with intermittent claudication, although treadmills are not accessible to most physicians. We hypothesized that global positioning system (GPS) recordings could monitor community-based outdoor walking and provide valid information on walking capacity in PAD patients.
We seek to determine if the use of the SafeSeal(TM) topical hemostasis patch is associated with reductions in time to hemostasis and time to ambulation compared to standard manual compression after arterial sheath removal following percutaneous coronary and peripheral intervention. We further seek to assess the safety of the SafeSeal patch compared to manual compression.
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.
The PACCOCATH FEM study is a randomized, double-blinded German multicenter trial on the efficacy and tolerance of a paclitaxel coated balloon catheter in prevention of restenosis after femoropopliteal angioplasty.
This study is designed to evaluate the safety and efficacy of autologous Vascular Repair Cells (VRC) for patients with peripheral arterial disease as a treatment for critical limb ischemia. The double-blind study is expected to enroll 150 patients, randomized into two patient groups. The treatment group will receive intramuscular (IM) injections of the VRCs into the affected limb; the control group will receive intramuscular injections with an electrolyte solution (without cells). Both groups will receive the standard of care appropriate for their medical condition.
The primary aim is to assess the effects of raising HDL cholesterol (the good type) with extended release niacin/laropiprant 2g (previously known as MK−0524A) versus matching placebo on the risk of heart attack or coronary death, stroke, or the need for arterial bypass procedures (revascularisation) in people with a history of circulatory problems. The secondary aim is to assess the effects of extended release niacin/laropiprant 2g daily on heart attack, coronary death, stroke, and revascularisation separately and to assess the effects on mortality both overall and in various categories of causes of death, and of the effects on major cardiovascular events in people with a history of different diseases at the beginning of the study.
In 5 Belgian hospitals, the data of 100 CLI-patients receiving the cryoplasty technique to treat their infrapopliteal arterial lesions will be collected. The treatment occurs strictly according the "Instructions For Use" of the CE-approved device (PolarCath Peripheral Dilatation System, Boston Scientific) and only data are collected that have been made available conform the Standard the Standards of Care for these patients.
This study will test how well a new contrast agent (dye) used in magnetic resonance imaging (MRI) can help visualize totally blocked arteries that normally supply blood to the neck, arms or legs. Currently used agents work well in visualizing normal or partly blocked arteries (arteries that have some blood flowing through them), but only poorly in totally blocked arteries. This study will see if a contrast agent called gadofosveset can better brighten images of completely blocked arteries. Gadofosveset is approved in Europe for use in MRI scans, but is still considered experimental in the United States. People 18 years of age or older with known or suspected total blockage of an artery to the neck, arm or leg may be eligible for this study. Participants undergo MRI scanning with gadofosveset contrast dye. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the subject lies on a table that can slide in and out of the tubular scanner, wearing earplugs to muffle loud noises that occur during the scanning process. The procedure lasts about 1.5 to 2 hours, during which the subject may be asked to hold his or her breath several times for as long as 5 to 20 seconds. During the procedure, gadofosveset is injected and several kinds of MRI pictures are taken to understand better how the new agent works. Subjects may be asked to undergo a second scan using conventional MRI contrast dye
The purpose of this study is to test a correction factor which would allow ankle brachial indexes taken in the seated position to accurately predict an ankle brachial index taken in the supine position.
The primary objective is to investigate in patients suffering from intermittent claudication due to Fontaine stage II Peripheral Arterial Disease (PAD) whether a 26-week treatment by HMR1766 on top of clopidogrel may result in an improvement of walking capacity, by comparing three doses of HMR1766 to placebo, and calibrating such effect versus cilostazol.
