Filter by:CABANA is a multicenter U.S. surveillance registry that will be conducted to compile early clinical outcomes data for the Carotid WALLSTENT Endoprosthesis and FilterWire EZ System in routine clinical practice and to assess the adequacy of the Boston Scientific Corporation (BSC) Carotid Stenting Training Program.
Hypothesis: Treatment with metformin in overweight non-diabetic individuals with coronary heart disease and on standard cardiovascular risk reducing agents including statins will have a beneficial impact on carotid artery atherosclerosis compared to placebo. Rationale: Once subjects have a heart attack, they remain at much higher than average risk of another heart attack and stroke, despite the best current therapies to lower their cholesterol and blood pressure and thin their blood. Many subjects with heart disease also have problems metabolising (i.e. processing) sugar even if they do not have diabetes. There is some evidence that metformin, a drug which improves sugar metabolism, decreases the risk of future heart attacks in diabetic patients. However, whether metformin further reduces the risk of heart disease beyond established treatments in people without diabetes is unknown. Method: The investigators will test the ability metformin, a drug with proven safety, to slow the progression of furring up (known as atherosclerosis) of blood vessels in non-diabetic subjects with heart disease. This will be achieved by treating 2 groups of subjects with metformin and placebo pills respectively. To measure atherosclerosis, the investigators will carry out ultrasound scans of the big blood vessels in the neck at the start of the study, after 1 year and after 1.5 years of therapy.The investigators will then be able to assess whether metformin has had a beneficial impact.
Atherosclerosis is a condition that occurs when fatty deposits build up along the inner walls of arteries. This study will examine the effectiveness of a combination of cholesterol-lowering medications at decreasing the fat content of atherosclerotic deposits in people who have coronary artery disease or carotid artery disease.
The purpose of this study is to examine the changes in the carotid artery when subjects receive high or low doses of rosuvastatin.
The aim of the present study is to examine the atherosclerotic plaque stability using in vivo and in vitro techniques and to investigate the influence of exercise, anti-diabetic, lipid-lowering and cannabinoids receptor antagonists on atherosclerotic plaque texture in patients with cardiovascular risk and animals prone to atherosclerosis.
Evaluate the safety and efficacy of the Protege Stent and Spider Device in the treatment of common and/or internal carotid artery stenoses for subjects that are high risk for carotid endarterectomy.
The purpose of this study is to determine how well patients undergoing carotid artery angioplasty and/or stent-supported angioplasty for the treatment of carotid artery stenosis will perform on a battery of tests to assess brain function before and after the procedure. This study will serve as a pilot project: (a) to determine incidence of neurologic/neuropsychometric change in patients undergoing carotid artery angioplasty and/or stent-supported angioplasty, and (b) to ascertain the time it takes for these changes to resolve.
The purpose of this study is to determine how well patients undergoing carotid endarterectomy will perform on a battery of tests to assess brain function before and after surgery as compared to a control group of patients undergoing spine surgery. This study will serve to: (a) determine incidence of neurologic/neuropsychometric change in patients undergoing carotid artery surgery, and (b) to ascertain the time it takes for these changes to resolve.
Background: During the first half of the 20th century, scalp irradiation was a standard treatment for induction of epilation in children suffering from Tinea Capitis. These children are now more than 50 years old and the aim was to investigate the possible association between their childhood low dose irradiation exposure and development of carotid atherosclerotic disease in adulthood. Methods: The study included 145 individuals treated by irradiation in their childhood, and 150 matched control subjects with no history of irradiation. B-mode ultrasound imaging and US Doppler were used to measure carotid and femoral stenosis and Intima-Media Thickness (IMT). Blood samples were taken for lipid profile and homocysteine evaluation.
This study is being done to determine if the acute administration of the drug Simvastatin reduces plaque tissue inflammation and plaque instability in patients undergoing carotid endarectomy
