Active clinical trials for "Infarction"

The goal of this monocentric observationnal study is to describe the characteristics of the myocardial infarction scar in terms of transmurality in residual LVEF>35% patients. The primary objective is to determine the frequency of the criterion "intramural scar ≥1.47cm2" (measured by MRI) in patients who presented with myocardial infarction with residual LVEF≥35%.

Despite the use of guideline directed optimal medical therapy, 12% of patients with stable coronary heart disease and 18% of patients with recent acute coronary syndrome experience recurrent major adverse cardiovascular events 1. The risk of recurrent cardiovascular events may be related to persistent elevation of thrombin beyond the index event 2,3 which leads to progression of cardiovascular disease by inducing inflammation, endothelial dysfunction and thrombosis 4. In patients with coronary heart disease, vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) have been explored as secondary prevention strategies and have shown cardiovascular benefits at the cost of higher bleeding events 5,6,7,8. howeverLeft ventricular thrombus (LVT) usually appearswithin 1 month after ST-segment elevation myocardial infarction (STEMI) and mostlyforms after anterior STEMI.9,11Although the prevalenceof LVT after acute myocardial infarction hasdecreased dramatically in modern times due to the progress of reperfusion therapy, LVT incidence in patients with anterior STEMI remains at 4% to 26%.10,12 It complicates acute myocardial infarction and is associated with a higher incidence of poor outcomes.9

This international, multicenter cohort study aims to investigate outcomes after treatment with extracorporeal cardiopulmonary resuscitation (eCPR) during cardiac arrest.

The investigators hypothesized that ticagrelor may enhance endothelial healing after DES implantation by increasing adenosine concentrations by the inhibition of adenosine uptake into erythrocytes, compared to clopidogrel. Thus, the investigators will evaluate the extent of endothelialization (stent strut coverage) and neointimal hyperplasia (neointimal thickness) 3 months after DES implantation by optical coherence tomography (OCT)

This study evaluates differences in the extent of myocardial necrosis noted by cardiac MRI in patients with ST-elevation myocardial infarction randomized to receive cangrelor during their percutaneous coronary intervention and compares them to patients randomized to not receive cangrelor.

ARC1779 is a novel drug being tested in patients undergoing angioplasty and stenting as their primary treatment for heart attack.

Dynamic 99mTc-Tetrofosmin CZT-SPECT myocardial perfusion imaging (MPI) is an advanced functional imaging technique giving important myocardial flow quantification added data in comparison with conventional MPI, especially in coronary multi vessel disease. A large-scale validation of diagnostic performances of myocardial flow reserve (MFR) estimated with Dynamic 99mTc-Tetrofosmin CZT-SPECT MPI would allow a non-invasive approach instead of invasive intra-coronary fractional flow reserve (FFR) measurement. The aim of this prospective study is to assess diagnostic performances of MFR calculated with dynamic 99mTc-Tetrofosmin CZT-SPECT MPI in comparison with invasive intra-coronary FFR measurement in patients with significant residual coronary arteries stenosis after ST-elevation myocardial infarction.

The BERLIN VT study is designed to evaluate the impact of prophylactic ventricular tachycardia (VT) ablation on all-cause mortality and unplanned hospital admission for congestive heart failure or symptomatic ventricular tachycardia/ventricular fibrillation (VF) when compared to VT ablation after the third appropriate implantable cardioverter-defibrillator (ICD) shock.

Cardiac rehabilitation (CR) is strongly recommended for patients with coronary heart disease. However, patient enrollment and completion of cardiac rehabilitation is low. This study will examine if a mobile phone intervention that uses a text messaging program can successfully promote participation in cardiac rehabilitation.

The CANARY (Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow) Study is a pivotal trial to evaluate criteria for defining a Lipid Core Plaque (LCP) that is at high risk of rupturing during standard of care therapy and causing intra-procedural complications. If plaques that require treatment are at higher than normal risk of causing intra-procedural complications, some life threatening, the treating physician is better informed and may opt to take precautionary measures to mitigate the risk or result of a complication. The CANARY Study is also designed to evaluate the feasibility of using a distal embolization protection device (EPD) as a means to prevent heart attacks triggered by the embolization of plaque during standard care therapy. It is thought that the EPD will prevent plaque from going downstream during treatment and obstructing other heart vessels. These obstructions could cause heart attacks by preventing blood from reaching heart muscle tissue.
