Active clinical trials for "Myocardial Infarction"

The current trial will compare the protective effect of ticagrelor and prasugrel on microvascular dysfunction in patients with revascularized ST elevation myocardial infarction.

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.

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 evaluate the clinical effect of intensive statin therapy before emergency PCI in patients with STEMI.

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 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 purpose of this study is to determine whether intracoronary transfer of autologous bone marrow cells can induce angiogenesis, subsequently improving regional myocardial perfusion, and finally resulting in improved systolic and diastolic left ventricular function in patients with myocardial infarction. 50 patients with stable left ventricle function will - with six months interval - receive two treatments with bone marrow transplantation intracoronary in vessels supplying dysfunctional myocardial territories and Coronary Artery Bypass Graft (CABG).

The investigators planned to evaluate the effects of liraglutide on left ventricular function in patients with non-ST-segment elevation myocardial infarction (NSTEMI).

Clopidogrel is crucial as antiplatelet treatment in patients undergoing percutaneous coronary intervention (PCI) with stent implantation and during one year after PCI, to prevent atherothrombotic complications. However, clopidogrel is ineffective in certain patients due to genetic mutation in CYP2C19 gene a specific enzyme in the liver required for metabolism of clopidogrel. Therefore, the purpose of this study is to test these patients genetically at bedside and prescribe an alternative drug such as Ticagrelor (90 mg twice daily) or prasugrel ( 10mg once daily or 5mg once daily if the patient older than 75 years or a body weight < 60kg) if they are carriers of the allele 2 or 3 of the mutated gene.
