Active clinical trials for "Myocardial Ischemia"

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..

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.

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 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.

Current guidelines recommend the addition of proton pump inhibitors (PPI) to patients taking double anti-platelet therapy (Aspirin and Clopidogrel) to prevent upper GI bleeding1. Many post percutaneous coronary intervention (PCI) patients are treated with dual anti-platelet medications as well as PPI to prevent upper GI bleeding. Recently, it was shown that PPI interact with the P450 system in the liver and reduce the platelet inhibitory effect of Clopidogrel2,3. Clopidogrel is activated by CYP2C19, which also metabolizes PPI4. Furthermore, a recent article showed increased mortality in patients taking PPI and clopidogrel compared with patients taking clopidogrel without PPI protection5. The degree of reduction in the platelet inhibitory properties of clopidogrel might vary among the different PPI4. The use of PPI for GI protection in patients treated with dual anti-platelet therapy is not based on randomized trials, but rather on expert opinion. Since H2 blockers are also effective in preventing acid secretion and are not known to interact with the P450 system that affects clopidogrel, the investigators hypothesized that these group of drugs will not interfere with the positive antiplatelet effects of clopidogrel and therefore will offer a good alternative treatment option.

The purpose of this study is to compare the efficacy and tolerability between clopidogrel resinate and clopidogrel bisulfate in patients with coronary heart disease (CHD) or CHD equivalents.

This study is divided into 5 arms: Randomized Clinical Trial (RCT): Prospective, randomized, active-controlled, single blind, parallel two-arm multi-center clinical trial in the United States (US) comparing XIENCE V® Everolimus Eluting Coronary Stent System (CSS) (2.5, 3.0, 3.5 mm diameter stents) to the Food and Drug Administration (FDA) approved commercially available active control TAXUS® EXPRESS2™ Paclitaxel Eluting Coronary Stent (TAXUS® EXPRESS2™ PECS) System US 2.25 mm non-randomized arm using 2.25 mm diameter XIENCE V® Everolimus Eluting CSS US 4.0 mm non-randomized arm using 4.0 mm diameter XIENCE V® Everolimus Eluting CSS US 38 mm non-randomized arm using 38 mm in length XIENCE V® Everolimus Eluting CSS Japanese non-randomized arm using XIENCE V® Everolimus Eluting CSS (2.5, 3.0, 3.5, 4.0 mm diameter stents) in Japan The TAXUS® EXPRESS2™ Paclitaxel Eluting Coronary Stent System is Manufactured by Boston Scientific.

The purpose of this study is to determine the effect of MC-1 on the combined incidence of cardiovascular death and nonfatal myocardial infarction (MI) up to and including 30 days following coronary artery bypass graft (CABG) surgery compared with placebo.

This is a multicenter, randomized, parallel group, placebo controlled study designed to evaluate the efficacy, safety, and tolerability of ezetimibe added to ongoing atorvastatin therapy compared with ongoing atorvastatin treatment alone. This study will involve subjects with primary hypercholesterolemia and coronary heart disease (CHD) who are currently being treated with atorvastatin and who would benefit from additional reduction in low-density lipoprotein cholesterol (LDL-C).
