Active clinical trials for "Myocardial Ischemia"

ALT-2074 (BXT-51072) belongs to a class of drugs called "glutathione peroxidase mimics." ALT-2074 works by imitating a substance produced in various tissues in the body, which prevents damage of the heart and blood vessels. Diabetic patients with a haptoglobin 2-2 genotype have poor cardiovascular clinical outcomes. The purpose of this study is to assess the safety, the pharmacokinetic profile and characterize the effect on biomarkers of inflammation and oxidative stress of repeat doses of ALT 2074. Subjects must be diabetic, with evidence of coronary artery disease and a haptoglobin 2-2 genotype

The purpose of this study is to establish safety and feasibility of utilizing Adipose-Derived Stem and Regenerative Cells (ADRC's) in patients who have suffered a ST-elevation acute myocardial infarction.

Myocardial damage occurs in up to 40% of cases when sensitive biomarkers are measured after coronary artery stenting. Such events have been associated with poor outcomes both at 30 days and long term. The cause of such damage is multi-factorial and includes distal propagation of atheromatous and thrombotic debris and the subsequent infiltration of the microcirculation with inflammatory cells. Individually or together these events can occlude the micro-circulation and lead impaired blood flow to heart muscle. The vasodilator adenosine is commonly used in cases of impaired flow in an endeavor to improve flow rate and limit myocardial damage. Unfortunately the efficacy of this therapy is limited. More recently, there have been clinical studies looking at the administration of adenosine before any potential damage by ballooning or stenting, in an effort to avoid poor distal flow post procedure and thus limit any myocardial damage. Although small numbers of subjects have been included in these trials, there have been encouraging preliminary data. The aim of this study is to assess whether the use of intra-coronary adenosine given directly into the target coronary artery prior to stenting can reduce the incidence of myonecrosis (heart muscle damage)over placebo. We also aim to assess whether this translates to better outcomes at 30 day follow up.

To demonstrate the safety and efficacy of the Driver Coronary Stent coated with 10 mcg/mm ABT-578 compared to the uncoated Driver Stent for the treatment of single de novo lesions in native coronary arteries 2.25-3.5 mm in diameter.

Objectives: A prospective investigation of the effect of omeprazole, a proton pump inhibitor, on the anti-platelet action of clopidogrel. The main decision criterion will concern change in VASP protein phosphorylation under treatment. Phosphorylation will be measured before and after administration of omeprazole versus placebo in patients undergoing clopidogrel treatment. Type of study: Single center, double blind, randomized parallel group study versus placebo, comparing two treatment groups: clopidogrel + omeprazole + standard regime (beta-blockers, atorvastatin, IEC, aspirin) clopidogrel + placebo+ standard regime (beta-blockers, atorvastatin, IEC, aspirin) Study population: 120 patients from the Cardiology Department of Brest University hospital, Brest (France), receiving a standard treatment comprising a loading dose of clopidogrel followed by a daily dose of 75 mg associated to 75 mg aspirin, will be randomized between 20 mg/day omeprazole and 20 mg/day placebo treatment groups. The efficacy of clopidogrel will be assessed by inter-group comparison on the VASP test. Study period: 7 days' treatment per patient. Total study period estimated at 6 months. Expected findings: The results should confirm the suspected negative effect of omeprazole on clopidogrel's impact on arterial thrombosis risk, secondarily allowing new recommendations to be drawn up for this association.

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 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.

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).

This was a double-blind randomized trial comparing 1200 mg per day of gemfibrozil with placebo in 2531 men with coronary heart disease, an HDL-C of 40mg/dl or less, an LDL-C of 140 mg/dl or less, and triglycerides of 300mg/dl or less. The primary outcome was nonfatal myocardial infarction(MI) or death from coronary causes. The median follow-up was 5.1 years. There was a risk reduction of 22% in the primary outcome (p=.0006) and 24% risk reduction in the combined endpoint of stroke, MI, and CHD death. The rate of events was reduced by raising HDL-C and lowering triglycerides without lowering LDL-C (N Engl J Med 1999;341:410-418).

In the ASCET study, 1000 patients with documented coronary heart disease will be randomized to either continued treatment with aspirin 160 mg/d or change to clopidogrel 75mg/d. Clinical endpoints will be recorded for at least 2 years and related to the initial aspirin response, assessed by the PFA-100® method, to investigate whether aspirin non-responders have higher composite event rate than responders or whether Clopidogrel treatment in patients non-responsive to aspirin will reduce their risk of future clinical events. The clinical events are the composite of unstable angina, myocardial infarction, stroke or death.
