Filter by: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)

To evaluate a new vascular sealant compared to control for the control of suture line bleeding after vascular reconstructive surgery.
The purpose of this study to compare balloon angioplasty (PTA) vs. cutting balloon angioplasty (CB-PTA) in terms of patency and postintervention inflammation in peripheral artery disease.
Critical limb ischemia is a condition where the blood circulation in the limbs, in most cases the legs, is decreased so that pain and non healing wounds ensue. Mostly, this is a sequel of arteriosclerosis and/or diabetes. If surgical and other methods for the improvement of blood supply for the leg have failed or are not possible, most of these patients will proceed to amputation of the leg. Bone marrow contains cells which can induce and augment the growth of new, small arteries called collateral arteries. It has been shown in animals and in some case series that the transplantation of a concentrate of the patient's own bone marrow with stem cells into the ischemic limb can improve the blood circulation via the induction of collateral growth. However, it is not known if this bone-marrow stem cell induced collateral growth is sufficient to avoid otherwise necessary amputations. Therefore, we conduct a study to compare the efficiency of concentrated bone marrow cells injected into the critically ischemic limb compared to a placebo procedure where only saline is injected. We think that the transplantation of autologous bone marrow will reduce the number of necessary leg amputations, reduce pain and induce wound healing. In this investigation, patients with limb threatening ischemia are randomly allocated either to the bone marrow group or to the placebo group. Patients in the bone marrow group will have their bone marrow harvested under sedation, and the bone marrow cells are concentrated. The cell concentrate will then be injected directly into the muscle of the diseased leg. Patients in the placebo group will undergo sedation as well but no bone marrow harvest is done, and saline is injected into the ischemic leg. The procedure will require about 1.5-2 hours, and the subjects will be admitted to a participating vascular Centre. Monthly examinations up to three months after the bone-marrow or placebo procedure are done. After the follow-up of three months, the rate of death and amputations and the wound healing process are compared between groups. Adverse and serious adverse events will be recorded during this time period. Diagnostic studies will be obtained to measure blood flow in the treated leg during the follow up period and include skin oxygen measurements, pressure recordings in the leg and arteriography. Also, quality of life, pain and wound healing will be assessed. After completion of the three months study participation, subjects who have been treated with placebo will be able to receive open-label bone marrow transplantation therapy.
Peripheral arterial disease (PAD) is the most common manifestation of systemic atherosclerosis and accounts for significant morbidity and mortality among end-stage renal disease (ESRD) patients. However, few studies have identified the prevalence and clinical impact of PAD in this specific population. Objectives: To perform a single-blinded parallel, controlled trial to examine the effect of cilostazol treatment on plasma VEGF levels, tissue factors , inflammatory markers (such as IL-6, hsCRP) levels, oxidative stress markers in ESRD patients with PAD Material and methods Fourty HD patients on maintenance HD for > 3months were enrolled in this prospective, single-blinded, randomized study. These patients were randomly allocated into 2 arms. After baseline assessment, patients in the treatment arm received 12 weeks of added on therapy with cilostazol 100mg/day. Blood pressure, heart rate, oxidative stress (malonyldialdehyde, protein carbonyl and ADMA), inflammatory markers (hsCRP, IL-6) and plasma, VEGF and tissue factors levels were measured before and after treatment.
This is a 12 month study of monthly injections of ranibizumab in subjects with polypoidal choroidal vasculopathy as diagnosed by fluoresceins/indocyanine green (FA/ICG) angiography.
This is a double blind crossover study designed to compare two different gadolinium products given at the same dose to patients undergoing MRA assessment of lower legs for the evaluation of peripheral steno-occlusive disease.
Patients with peripheral artery disease have decreased blood flow to exercising muscle causing pain. This decreased blood flow to the muscle affects the level of acylcarnitines which in turn decreases the level of carnitine. Carnitine allows muscles to function properly. This study will test the safety and efficacy of Propionyl-L-Carnitine taken in combination with a monitored exercise training program.
The purpose of this study is to determine if the contrast agent is effective and safe in the Magnetic Resonance Imaging (MRI) of vascular diseases in patients of Chinese origin.
