Active clinical trials for "Myocardial Ischemia"

The study will assess the change in coronary atherosclerotic disease as determined by intravascular ultrasound (IVUS) for aliskiren compared to placebo when given in addition to standard therapy in patients with coronary artery disease (CAD) and a blood pressure in the pre-hypertensive range.

The purpose of this study is to see if taking a cholesterol lowering drug Lipitor (Atorvastatin Calcium)will increase the number of endothelial progenitor cells (EPC's) circulating in the blood of heart failure patients taking this cholesterol-lowering drug, and if this will also show an improvement in the damaged areas of the patient's hearts as documented by MRI scans.

This study will evaluate the efficacy of anacetrapib (100 mg) for 24 weeks relative to placebo, on plasma concentrations of Low Density Lipoprotein Cholesterol and assess the safety and tolerability of anacetrapib (100 mg) in participants with CHD/CHD risk-equivalent disease on stable dose regimen of statin with or without other lipid-modifying therapy. The two year extension to this study will further evaluate the long-term safety profile and efficacy of anacetrapib in CHD/CHD-risk equivalent patients who are on ongoing therapy with a statin with or without other lipid-modifying therapy.

Endothelial dysfunction is an early marker of atherosclerosis and is found in patients (pts) with coronary (CAD) and peripheral artery disease (PAD). Statin-therapy has been shown to improve endothelial function in pts with CAD or PAD by reducing LDL-cholesterol and inflammatory markers. B-group vitamin-supplements have variable been reported to have positive or neutral effects on endothelial function. Therefore, we want to compare the effect of rosuvastatin and B-group vitamin supplementation on endothelial function of the forearm resistance vessels in pts with cardiovascular disease.

This study will assess the effect of RO4607381, compared to placebo, on atherosclerotic plaque in patients with coronary heart disease (CHD) including patients with other CHD risk factors. After a pre-randomisation period during which positron emission tomography computed tomography (PET/CT) and MRI will be conducted, patients will be randomized to receive either RO4607381 600mg po daily, or placebo po daily. PET/CT and MRI scans will be taken at intervals during the study. The anticipated time on study treatment is 2 years, and the target sample size is 100 individuals.

This study will assess the safety, tolerability and efficacy of RO4607381 in patients with coronary heart disease (CHD) or CHD risk equivalents. Patients will be randomized to receive either RO4607381 600mg po daily or placebo po daily. Endothelial function will be measured by flow mediated dilatation and blood pressure monitoring will be assessed. The anticipated time on study treatment is up to 12 months, and the target sample size is up to 500 individuals.

The purpose of this study is to compare the effect of 8 weeks of treatment with Rosuvastatin with 8 weeks of treatment with Atorvastatin on low density lipoprotein cholesterol level in subjects with hypercholesterolemia and coronary heart disease (CHD) or at high risk of CHD..

This is a multicenter, prospective study designed to demonstrate the performance and safety of the FiberNet Embolic Protection System when used as an adjunctive device during saphenous vein graft (SVG) intervention.

Effects of statin and ezetimibe association on kinetics of artificial chylomicrons in men with stable coronary heart disease (CHD). Background: The rate (kinetics) of chylomicrons removal from circulation have been correlated with the incidence and severity of atherosclerotic lesions; a number of studies demonstrated lower plasmatic clearance of chylomicrons in patients with CHD compared to patients without this condition. It was also demonstrated a correlation among LDL-C levels and removal of chylomicrons remnants by a technique employing artificial chylomicrons. The investigators also know that higher doses of more potent statins are more effective in chylomicrons removal than lower doses or less potent statins; nevertheless, the effect of the isolated use of statin has not been completely studied up to now. Study design: The investigators propose to study 26 outpatients volunteers with chronic CHD, followed at the Heart Institute - INCOR - of the School of Medicine, University of São Paulo. Following a period of six weeks of washout from any cholesterol reducer, the kinetics of chylomicrons removal by a technique of emulsion of radiolabeled artificial chylomicrons will be evaluated. Lipid fractions, hepatic enzymes and CK will be measured. Initially patients will be randomly allocated to receive simvastatin 20 mg /day (n= 13) or ezetimibe 10 mg/day (n=13) for six weeks. At the end of this period, kinetics of chylomicrons removal and laboratorial measurements will be repeated (Period 1). In the next period (Period 2) patients will receive simvastatin 20 mg/ ezetimibe 10 mg (n=13) or simvastatin 80 mg (n=13) for additional six weeks; at the end of this period, the evaluations will be repeated (third and last evaluation). The aim of this study is to further understand chylomicrons metabolism in patients with chronic coronary disease receiving cholesterol reducers at different dosage regimes.

The goal of the study is to investigate the impact of a 4 week treatment with pioglitazone (in comparison to placebo) on biomarkers for atherosclerosis and cardiovascular risk, as well as the degree of activation of the immune system, when given on top of an anti-diabetic treatment (metformin and/or sulfonylurea drugs) that has already resulted in good glycemic control.
