Filter by:We are conducting a clinical research trial to determine the role of self-managed walking therapy to improve walking ability in patients with diabetes mellitus and peripheral arterial disease (PAD). PAD, commonly referred to as poor circulation in the legs, is a very common disease in patients with diabetes mellitus. For patients with PAD, there is a significant risk for poor walking ability and limb loss. One major treatment for PAD is walking therapy but the traditional methods for the delivery of this treatment have required frequent visits to a university or hospital-based site. We will address the role of self-managed walking program, to be conducted at or near the home, to improve limb function.
Prospective, multicenter, non-randomized, single-arm registry to evaluate the safety and effectiveness of the iCAST Covered Stent System in the treatment of patients with symptomatic claudication or rest pain and angiographic confirmation of de novo or restenotic lesions in the common and/or external iliac artery.
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.
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.
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.
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.
A cholesterol/lipid profile screening project of high risk patients with hyperlipidaemia (secondary prevention) who already receive cholesterol-lowering therapy. Lipid profile and rate of patients who are treated to target (which is <100mg/dl for patients with high risk and <70mg/dl for patients at very high risk) are screened (office-based specialists). The doctors therapy decisions after the screening and possible reasons for these decisions will be documented. Our aim is to evaluate dosing habits, to evaluate how many patients are treated to their LDL-C target and to underline the importance of treating patients to their cholesterol targets.
