Filter by:The purpose of this study is to determine whether immunosuppression by tacrolimus, mycophenolate mofetil, and prednisone compared to conversion to sirolimus, mycophenolate mofetil, and prednisone affect the progression of atherosclerosis in renal transplant recipients.
The primary objective of this randomized, double blind, placebo controlled pilot study is to determine if therapies aimed at lowering LDL cholesterol (HMGCoA reductase inhibitor – simvastatin) or increasing HDL cholesterol (Niaspan) will induce regression of carotid atherosclerotic plaque in vivo using MRI imaging techniques. MR plaque morphology at baseline will be compared to that after 6 and 12 months of therapy and changes in MR characteristics will be compared to changes in lipoprotein parameters and urinary isoprostanes. The effect of moderate LDL reduction, aggressive LDL reduction and the combination of aggressive LDL reduction and HDL elevation on MRI plaque characteristics will be compared by randomly assigning subjects (n=69) with carotid disease (>30% stenosis by ultrasound criteria) to one of three treatment arms; 1. Simvastatin 20 mg daily and placebo Niaspan (n=23) 2. Simvastatin 80 mg daily and placebo Niaspan (n=23) 3. Simvastatin 20 mg daily and active Niaspan (n=23) Treatment group 2 and 3 will have roughly equivalent LDL lowering because of the synergistic LDL lowering effect of the combination of simvastatin and Niaspan.
The purposes of the registry are: 1) To provide an ongoing post-market surveillance mechanism to document clinical outcomes. 2) To provide additional information that the RX ACCULINK™ and RX ACCUNET™ can be used safely by a wide range of physicians under commercial use conditions. 3) To evaluate the adequacy of Abbott Vascular's physician training program.
To collect clinical outcome and device performance data on the FDA 510(k)-cleared Emboshield® BareWire™ Rapid Exchange Embolic Protection System and FDA-approved Xact® Rapid Exchange Carotid Stent System when used under commercial use conditions by a broad group of physicians entering the study with differing carotid artery stenting experiences.
To assess the safety and feasibility of Volcano Corp Eagle Eye Gold Catheter system to correlate the presence and characteristic of carotid artery atherosclerotic disease with anatomic and histologic analysis.
The purposes of this study are to determine: 1. Inter-site variability in CIMT image measurement using SonoCalcTM. 2. If non-sonographer health care professionals working in an office practice setting can be trained to follow a carotid scanning protocol that permits (a) accurate measurement of CIMT and (b) determination of plaque presence. 3. If (a) CIMT measurements and (b) determination of plaque presence by non-sonographer health care professionals are bioequivalent to those made by a core laboratory. 4. If CIMT measurements and plaque assessment performed in office practices lead to meaningful changes in patient and physician behavior related to cardiovascular disease prevention.
To determine the rate of progression of sub-clinical cardiovascular disease as measured in carotid intimal medial thickness over a period of 8 to 10 years.
The primary objective of this study is to compare the safety and effectiveness of the Cordis Nitinol Carotid Stent and Delivery Systems (5.5 F and 7 F) with the ANGIOGUARD XP distal protective device to CEA in the treatment of carotid artery disease in patients at increased risk for surgery.
The primary objective of this study is to assess the outcomes of stenting with distal protection in the treatment of obstructive carotid artery disease during peri-approval/initial commercialization in relation to the outcomes of the Sapphire Clinical Trial. The devices to be utilized are the Cordis PRECISE Nitinol Stent Systems and the Cordis ANGIOGUARD™ XP Emboli Capture Guidewire (ECGW).
The EFFERVESCENT trial is designed to evaluate the effects of a specific ARB, called valsartan, on atherosclerosis. The investigators want to know if treatment with valsartan will increase the blood levels of markers responsible for repair of the vessel wall, reduce oxidation and inflammation, improve the function of the blood vessels, and arrest or slow down the progression of atherosclerosis over time.
