Active clinical trials for "Myocardial Ischemia"

The purpose of this study is to determine whether rivaroxaban in addition to standard care reduces the risk of the composite of cardiovascular death, myocardial infarction, or stroke in patients with a recent acute coronary syndrome compared with placebo.

Many trials suggested that lipid lowering therapy could significantly reduce cardiovascular events. Enhancing stability of vulnerable plaque is probably the main reason by which statins reduce adverse coronary events. The size of lipid core and the fibrous cap thickness (FCT) are the major determinants of plaque vulnerability. So, it is very important to accurately evaluate changes in plaque after stains therapy. Previous reports suggested that intensive lipid lowering therapy provide more significantly clinical benefit compared with moderate lipid lowering therapy.Such benefit may contribute to the changes in following parameters: FCT, lipid arc(quadrants), TCFA, macrophage, plaque disruption, and thrombus measured by OCT, and plaque burden and remodeling index by IVUS. Current intravascular imaging modalities, such as optical coherence tomography (OCT) and intravascular ultrasound (IVUS) can provide in vivo quantitative and qualitative information of coronary plaques. However, there were few studies aimed at monitoring the progression of coronary plaques in patients receiving statin therapy by OCT combined with IVUS. Therefore, the study we designed were to compare the effect of the rosuvastatin 10mg, atorvastatin 20mg and atorvastatin 60mg treatment on the changes in FCT and lipid core arc by OCT and plaque burden by IVUS of coronary atherosclerotic plaques.

Ischemic cardiomyopathies are a leading cause of death in both men and women. When a person has a heart attack, blood is unable to reach a certain area of the heart, and if the blood supply is not re-established quickly, that area of the heart can suffer permanent damage. While recovery from a heart attack can be managed through medications and lifestyle changes, these treatments can not reverse the all damage to the heart. Current research is focusing on the development of cell-based therapies using stem cells to repair organs that have been irreversibly damaged by disease. A specific form of stem cells, called adult mesenchymal stem cells (MSCs), has shown promise for heart repair. This study will evaluate the safety of injecting MSCs directly into the heart to repair and restore heart function in people who have had a heart attack and who have chronic myocardial ischemia with heart failure.

The purpose of this study is to assess the safety and performance of the BVS Everolimus Eluting Coronary Stent System (EECSS) in the treatment of patients with a maximum of two de novo native coronary artery lesions located in two different major epicardial vessels. Currently in development at Abbott Vascular. Not available for sale in the United States.

The purpose of this study is to investigate dose range, safety and efficacy of RVX000222 in subjects with stable coronary artery disease.

The purpose of this study is to assess whether the new Kaname coronary stent is safe and effective for the treatment of patients with coronary artery disease.

It is becoming increasingly clear that North Americans prefer dietary approaches to enhance health in favour of pharmaceutical approaches. Although the consumption of various phytosterol (PS)-enriched foods have been shown to be effective in lowering plasma cholesterol in a variety of food matrices, the lipid-lowering potential of PS-enriched soymilk has not been investigated. Therefore, the objective of this investigation was to examine the lipid-lowering efficacy of a PS-enriched soymilk beverage in comparison to a 1% dairy milk control. Twenty-three hypercholesterolemic subjects (Total-cholesterol and LDL-cholesterol ≥ 5.0 and 3.5 mmol/L, respectively) consumed 3 tetrapacs per day of a phytosterol-enriched soy beverage providing 1.95g PS/d or a 1% dairy milk control. The study was conducted as a 28 d controlled dietary intervention according to a completely randomized, two-period cross-over design.

The purpose of this study is to determine whether Ateronon, a nutritional supplement that contains lycopene from tomatoes has a favorable effect on carotid atherosclerosis, lipid levels, and other biomarkers of coronary heart disease. The trial was stopped early due to insufficient financial support from the initial study collaborator, Cambridge Theranostics Ltd. Collected patient data are sufficient for final trial-based analyses to be conducted with financial support from the new study collaborator, CamNutra Ltd. The data will still be analyzed according to the original study aims.

The primary objective of this study is to assess the safety and effectiveness of same sitting, simultaneous hybrid robotic assisted coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in the treatment of obstructive multivessel coronary artery disease. A secondary objective is the assessment and standardization of optimal operator techniques and comparative study of patients undergoing CABG during study period.

There is conflicting evidence in the literature suggesting that the use of proton pump inhibitors (PPIs), and/or some statins can interfere with clopidogrel antiplatelet effect and result in adverse cardiovascular outcomes in patients treated with coronary artery stents and dual antiplatelet therapy. The primary aim of the study is to determine the effect of various currently used PPI on platelet aggregation in patients undergoing percutaneous coronary intervention (PCI) and treated with dual antiplatelet therapy. The secondary aim of the study is to evaluate how statins and 2C19*2 polymorphism modulate the effect of PPI on clopidogrel efficacy.
