Filter by:The whole study is divided in 4 parallel protocols. The first protocol estimates the reliability of the technique through test-retest recordings. The second protocol aims to prove that exercise Tcpo2 is efficient to estimate the benefit of proximal revascularisation on proximal and distal ischemia in patients suffering stage two lower extremity arterial disease. The third protocol aims at estimating with exercise tcpo2 the eventual apparison of proximal ischemia after aorto-bi-femoral bypasses. The last protocol is a transversal study of patients with aorto-bi-femoral bypasses aiming to analyse the presence of proximal and distal symptoms and ischemia. The hypothesis for protocol 2 is that TcpO2 at exercise is significantly improved after surgery at the aortic and primary iliac artery. The hypothesis for protocols 3 and 4 relates on the hypothesis that a significant number of patients benefiting aorto-bi-femoral bypass suffer isolated proximal pain/ischemia after surgery. Amendement to the project has been recently validated to study the neurologic and bone complication of chronic vascular ischemia
Comparison of two kinds of protheses for bridging of the femoropoplitea and/or femorotibiale: PTFE with or without bounded heparin
The purpose of this study is to provide information on the risks and benefits of routine blood pressure lowering (regardless of blood pressure level), and intensive lowering of blood glucose levels, in patients with Type 2 diabetes at high risk of cardiovascular events. The major outcomes of the study will be cardiovascular events (heart attack, stroke or dying as a result of cardiovascular disease), as well as new or worsening diabetic eye and kidney disease.
Vascular diseases (cardiac events, strokes, peripheral vascular disease) remain the number one killer in Canadian society as well as the leading cause of hospitalization and days spent in the hospital. A 1996 estimate placed Ontario's vascular disease financial burden at $5.5 billion in total. Any intervention which lowers vascular risk, will have a direct impact on the quantity and quality of life and costs of health care. Further integration of health professionals in teams focused on chronic disease management in individuals and populations is also ripe for further evaluation. Increased collaboration between family physicians, physician specialists, nurse practitioners, and pharmacists are generally thought to be beneficial for patient outcomes, but the literature is inconclusive and their cost-effectiveness is unproven. In addition, combining centralized electronic up-to-date information on the patient's status with evidence-based recommendations and the ability to communicate either electronically or by phone is expected to result in improved access to care, quality of care, continuity of care and increase cost-effectiveness of chronic disease management. COMPETE III builds on the researchers' previous work to study an electronic vascular tracking and decision support system shared by patients and their physicians, combined with a clinical care coordinator and automated telephone support system. The researchers are evaluating its impact on vascular risk processes and outcomes, perceived usefulness, ease of use, need for improvement, medication adherence, quality of life and patient goals and motivation. Study hypothesis: Patients at increased risk of vascular events, if connected with their family physicians, medical specialists and care coordinator via an electronic network (Web, fax and telephone) sharing an intensive tracking, advice and support program, will lower their vascular risk more than those in usual care.
The Zilver® PTX™ Drug Eluting Vascular Stent is indicated for the treatment of symptomatic vascular disease of the above-the-knee femoropopliteal artery (ranging from 4 mm to 9 mm in reference vessel diameter) for lesions up to 7 cm long. The clinical trial is stratified by lesion length. The trial will be conducted in 2 phases, with Phase 1 enrolling patients with lesions less than 7 cm long. Phase 2 of the trial will include longer lesions (up to 14 cm long) and will be initiated upon approval by the Food and Drug Administration (FDA).
The purpose of this Phase 2 clinical research study is to examine the safety of an experimental gene transfer agent, Ad2/HIF-1α/VP16, and its ability to stimulate the growth of new blood vessels from existing blood vessels (a process called angiogenesis) in an attempt to improve the flow of blood in the legs of patients with peripheral arterial disease (PAD). Specifically, this study will enroll patients with severe intermittent claudication (IC) which is the stage of PAD in which a patient's walking ability is severely limited, causing pain in the legs upon exercise due to inadequate blood flow to the muscles of the lower limbs.
This is a phase II, multicenter, randomized, double-blind, placebo-controlled trial in which subjects with intermittent claudication (IC) will be randomized to receive a single treatment of VLTS-934 (84 mL, or a total of 420 mg poloxamer 188) or placebo (84 mL saline) administered as 21 intramuscular (IM) injections of 2 mL each, bilaterally into the lower extremities during one procedure to evaluate the safety, tolerability, and potential activity of VLTS-934 as compared with a saline placebo.
The purpose of this study is to determine if folic acid supplementation can slow down atherosclerotic progression, age-related cognitive decline and age-related hearing loss.
The purpose of this study is to compare the effects of nutrition, a supervised treadmill exercise program, and supervised progressive resistance training program on peripheral arterial disease.
The purpose of this study is to assess the efficacy and safety of the study drug, known as "ATG Fresenius S," which is sometimes called "EZ-2053," to prevent a lung transplant patient's body from rejecting a transplanted lung or lungs.
