Active clinical trials for "Carotid Artery Diseases"

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; Simvastatin 20 mg daily and placebo Niaspan (n=23) Simvastatin 80 mg daily and placebo Niaspan (n=23) 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 this study are: To provide additional safety and effectiveness information on the commercial use of Protégé™ GPS™ and Protégé™ RX Carotid Stent Systems and the SpiderFX™ Embolic Protection Device. To evaluate rare and unanticipated adverse events. To evaluate the physician level of experience with carotid artery stenting procedures with adverse event rates.

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 objective of this study is to provide an ongoing evaluation of clinical outcomes associated with the GORE Flow Reversal System and the GORE Embolic Filter when used for embolic protection during carotid artery stenting.

The aim of this study was to measure the effect of moderate and intensive lipid-lowering treatment with rosuvastatin on the carotid intima-media thickness (CIMT) as a surrogate marker of cardiovascular risk.

The purpose of this study is to find the optimal dose from 3 different dose levels - 0.15 mL, 0.5 mL and 1.5 mL of Optison in assessing the presence of disease of the carotid arteries when comparing pre-contrast to post-contrast ultrasound (U/S) by dose group.

The objective of this post-market clinical follow-up study is to evaluate the clinical outcomes of patients receiving PhotoFix as a patch within a vascular repair or reconstruction procedure.

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.

This study will evaluate the effects of vitamin E supplementation in retarding the progression of common carotid artery intima-media thickening in African Americans.

The LOTUS Study is intended to demonstrate the usability of the MICHI Neuroprotection System (MICHI NPS) or MICHI Neuroprotection System with filter (MICHI NPS+f) for use in subjects who are candidates for Carotid Artery Stenting (CAS). It is a prospective, single arm study in which a maximum of 30 study subjects, and a run-in enrollment of up to 10 subjects will be followed immediately post-op and at 30 days.
