Filter by:The purpose of this study is to develop new ways of imaging fatty blockages in the leg arteries to improve upon techniques used now and to develop new ways of understanding how new treatments may affect the disease.
In an observational multi-centre study (CHALLENGE), the effects were assessed of starting treatment with low doses of rosuvastatin in statin naive patients with a history of coronary heart disease (CHD), peripheral vascular disease (PVD), cerebrovascular accident (CVA), transient ischemic attack (TIA) or diabetes (DM), on low-density lipoprotein cholesterol (LDL-C) goal achievement. Also proportional changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG) and the ratio TC/HDL-C were studied.
Sixty patients with mild-to-moderate PAD (ABI 0.4-0.9) and hypertriglyceridemia (>200 mg/dl) already treated with statins will be imaged at baseline and randomized to Lovaza and placebo for 12 months. MR imaging will be repeated at the end of the 12-month period. We hypothesize that treatment of hypertriglyceridemia in patients with PAD with Lovaza will reduce atherosclerotic plaque volume in the superficial femoral artery (SFA) by 2% over 1 year compared to placebo. Secondary aims will be to show improved plaque characteristics (thickened fibrous cap, reduced lipid-rich necrotic core, improved exercise calf muscle perfusion using first-pass contrast enhanced MRI and improved exercise treadmill performance with Lovaza compared to matching placebo.
Primary objective is to demonstrate the superiority of riferminogene pecaplasmid over placebo in the prevention of major amputation above the ankle of the treated leg or of death from any cause, whichever comes first, in critical limb ischemia (CLI) patients with skin lesions. Secondary objectives are to evaluate: - The efficacy of riferminogene pecaplasmid versus placebo for delaying the time to major amputation; - The efficacy of riferminogene pecaplasmid versus placebo for delaying the time to death; - The safety of riferminogene pecaplasmid in the study population.
This research project is investigating the relationship between body weight and function of the leg veins using a special non-invasive technique known as venous plethysmography.
The occurrence of Peripheral Vascular Disease has been increasing which includes the large artery in the upper leg called Superficial Femoral Artery (SFA). The Peritoneal Lined Stent has been developed as a new method for treating narrowed area in the SFA. This research study will determine the safety and effectiveness of the Peritoneal Lined Stent in keeping th Superficial Femoral Artery open and allowing blood to flow in the leg.
The objective of the study is collect data on the GORE VIABAHN Endoprosthesis with Heparin Bioactive Surface in the treatment of chronic Superficial Femoral Artery disease. Device patency at 12 months is the primary endpoint.
The investigators propose confirm and extend the findings of open studies on the apparent efficacy of bone-marrow derived mononuclear cells for the induction of arteriogenesis in patients with severe claudication or critical leg ischemia and pay special attention to the influence of diabetic disease on the outcome of the study and to the possible pro-atherogenic/ pro-inflammatory effects of BM-MNC injections.
This is an open label pilot study to evaluate the efficacy and the safety of the Flowaid device in increasing local circulation in the legs. 15 patients with a diagnosis of Peripheral Vascular Disease will be enrolled in this study. They will recieve tratment with the Flowaid device and monitored continuously by means of Laser Doppler Flowmetry as well as by tcPO2 and Digital Thermography. Subjective data will also be collected.
Patients with peripheral arterial disease (PAD) experience significant functional limitations due to ischemic symptoms (claudication) and are at high risk for CVD morbidity and mortality resulting from untreated cardiovascular disease (CVD) risk factors and aggressive atherosclerosis. The overall Goal of this randomized controlled clinical trial is to examine the synergistic effect of a multifactor risk reduction on walking distance, blood flow and quality of life in 300 patients with PAD. Specifically, we will compare the effects of 24 months of a novel, yet well-tested multiple risk factor reduction program, the Health Education and Risk Reduction Training (HEAR2T) Program for PAD versus enhanced standard care on: 1) symptom limited walking distance as assessed by treadmill exercise testing and walking impairment questionnaire; 2) endothelial function as measured by flow mediated vasodilation (FMVD) via brachial artery ultrasound. We will also explore the association between FMVD and decreased oxidative stress (as measured by oxygen radical absorbance capacity and urinary isoprostanes) and reduced degradation of nitric oxide (NO) and/or increased NO biosynthesis (as measured by urine nitrogen oxide, plasma nitrogen oxide, plasma asymmetric dimethylarginine, plasma, urine and platelet cyclic GMP). Secondary hypotheses examine the association between reducing CVD risk factors, improved endothelial function, increased walking distance, improved quality of life and number of metabolic syndrome abnormalities in PAD patients. Significance. This study will contribute to evidence on the efficacy of multiple risk factor reduction on improving physical function and quality of life in the understudied, elderly PAD patient. This study will also provide preliminary evidence for the biological basis for the efficacy of multifactor risk reduction in restoring vascular homeostasis, critical because of its role in antiatherogenesis and maintaining vasoreactivity, both necessary for slowing the progression of atherosclerosis.
