Active clinical trials for "Myocardial Infarction"

International guidelines support the use of a full-dose heparin (anticoagulants) during coronary intervention. However, a lower dose of heparin may be adequate, thanks to advances in angioplasty techniques and the widespread use of pretreatment with two antiplatelet agents. Thus the investigators designed a study comparing safety and efficacy of standard dose heparin (100 UI/Kg) versus low-dose (50 UI/Kg) in patients undergoing coronary angioplasty who are on aspirin and clopidogrel at the time of the procedure.

Evaluate the efficacy, Safety and Pharmacokinetics of Intravenous single injection LC28-0126 immediately before Percutaneous Coronary Intervention (PCI) in Patients with ST-segment Elevation Myocardial Infarction (STEMI).

Restoring the patency of the coronary vessels and providing the ischemic myocardium with reperfused blood can cause additional tissue damage. A key element of ischemia and reperfusion (I/R) injury and major determinant of the evolution of damage in the affected myocardium is the inflammatory response. The main objective of the study is to evaluate the efficacy of colchicine in reducing I/R injury by effectively modulating the inflammatory response in the reperfused myocardium.

Myocardial infarction (MI) causes loss of myocytes and may lead to loss of ventricular function, morbidity and mortality. The most effective therapy is early reperfusion of the ischemic myocardium by percutaneous coronary intervention (PCI). Reperfusion limits myocardial ischaemic necrosis, but also induces inflammation, oxidative stress and calcium overload: a process referred to as reperfusion injury leading to necrosis and apotosis. Glucagon Like Peptide-1 (GLP-1) is an incretin hormone that has shown to activate anti-apoptotic enzymes, reducing reperfusion injury. GLP-1 agonists have been demonstrated to be cardioprotective in several animal studies and in a single small non-randomized clinical study. In this pilot study we will assess the safety and efficacy of GLP-1 receptor agonist Exenatide infusion compared to placebo in patients with an acute myocardial infarction undergoing primary PCI. A total of 40 patients will be included in this single centre prospective randomised placebo controlled two-arm pilot study. Patients who are to undergo a primary PCI for a first acute ST elevation myocardial infarction are randomly assigned to placebo or Exenatide 5ug bolus in 30 minutes, followed by a continuous Exenatide infusion of 20ug/ 24 hours for 72 hours. Blood samples are obtained for assessment of enzymatic infarct size and Exenatide levels. Side effects of Exenatide are stringently monitored. Cardiac function will be measured using Cardiac Magnetic Resonance Imaging (CMRI) and 3D echocardiography at 1 week and 4 months post MI. Infarct size will be assessed by means of the final infarct size at 4 months post MI as a percentage of the area at risk at 1 week post MI. Furthermore we will compare the RNA profile of both groups.

The purpose of this study is to evaluate the clinical effect of intensive statin therapy before emergency PCI in patients with STEMI.

The aim of this study is to compare the effectiveness of four different strategies for preventing the ventricular postinfarction remodelling: 1) Conventional treatment for reperfunded extensive acute myocardial infarction, 2) Autologous bone marrow stem-cells intracoronary transplantation 3) mobilization of bone marrow stem-cells induced by granulocyte colony-stimulating factors (G-CSF); and 4) combined treatment (stem-cells transplantation plus mobilization with G-CSF).

The purpose of this study is to discover genes that may cause Coronary Artery Disease (CAD) or Arteriovenous Malformation (AVM).

The primary objective of this study is: comparison of a safety and effectiveness of third generation DES (biolimus A9 and everolimus) in patients with STEMI treated by primary PCI with OCT guidance. A rate of 9 month MACE (deaths, myocardial infarction, ischemia driven TLR) will be assessed in both groups. The secondary outcomes are a comparison of (using OCT): number of uncovered stent struts number of malapposed stents struts in-stent neointimal volume in-segment assessment of vessel wall response to DES

The primary objective of this study is to investigate whether intracoronary bolus administration of abciximab is superior to intravenous bolus administration in improving myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.
