Active clinical trials for "Peripheral Vascular Diseases"

The purpose of this study is to evaluate whether clopidogrel 75 mg daily on a background of aspirin 75-100 mg/d for clinically indicated duration or for an additional 12 months will lead to an increased rate of primary patency, limb salvage, non-fatal myocardial infarction (MI), ischemic stroke, and survival, in patients receiving endovascular treatment of PAD at end of study treatment.

The hypothesis of this proposal is that in subjects with PAD, regular consumption of a high nitrate supplement which raises plasma nitrite, in conjunction with 12 weeks of supervised exercise training at the limb ischemic threshold (SET) will produce a greater clinical benefit (increases in COT and PWT) than placebo plus supervised exercise at the limb ischemic threshold (PET).

European 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)

The purpose of this study is to evaluate whether the results of drug eluting balloon are non-inferior to the Nitinol stent implantation in the femoropopliteal segment.

The purpose of this study is to investigate whether daily treatment with intermittent pneumatic leg compressions (IPC) following a nonsurgical vascular procedure improves circulation and enhances walking distance.

The Zilver PTX Registry Study is a prospective, non-randomized, open-label, multicenter single-arm study enrolling patients in Europe, Asia, and North America with de novo or restenotic (including in-stent restenosis) lesions of the above-the-knee femoropopliteal artery (SFA). The primary endpoint of the study is event-free survival (EFS) at 6 months.

An estimated 8 million individuals in America are affected by peripheral arterial disease (PAD), blockages of the leg arteries that can cause excruciating calf pain when walking. PAD can have a tremendous impact on patients' quality of life. It is also associated with high rates of heart attacks and premature death. While there are a number of treatments, there have been few previous studies that have prospectively examined treatment patterns for PAD or sought to systematically identify opportunities to improve care. Most importantly, there have been no rigorous studies examining the impact of the disease from patients' perspectives - their symptoms, function and quality of life - as a function of different patient characteristics and treatments. The PORTRAIT study (Phase II) will systematically document the treatments and health status (symptom, function and quality of life) outcomes of 840 US patients over the course of one year (assessments at baseline, 3, 6, and 12 months) from 10 centers to address these gaps in knowledge. It will illuminate whether disparities in treatment or health status outcomes exist as a function of patients' age, gender, race, socioeconomic or psychological characteristics. PORTRAIT will substantially elevate the field and identify critical gaps in the way PAD is currently managed, including potential disparities in care, so that the quality of care can be improved.

The hypothesis being tested is that in patients with stable claudication and documented PAD, omega-3 supplementation for 1 month will lead to improvement in endothelial function as measured by flow-mediated, brachial artery vasodilation (FMD), as well as improvement in the vascular inflammatory profile as measured by a panel of established circulating inflammatory biomarkers.

The study tests the use of a portable mechanical compression device (FM220, Flowmedic, USA) for the treatment of claudication and peripheral arterial disease. Major endpoints are improved exercise tolerance and relevant blood pressure ratios

BALI (Bone marrow Autograft in Limb Ischemia) is a randomized double-blind trial comparing implantation of bone marrow - mononuclear cells versus placebo in patients presenting with critical leg ischemia and no surgical option. The main end point is the survival without major amputation 6 months after implantation. Biological studies are performed on bone marrow mononuclear cells (BM-MNC) to evaluate their angiogenic properties.
