Filter by:This study is being done to determine if a picture taking test of the heart, positron emission tomography/computed tomography (or cardiac PET/CT), can identify the blockages in the heart arteries that lead to heart attacks when compared to the standard of heart catheterization.
This is a prospective, open label, randomized trial of 100 patients who present to the cardiac catheterization laboratory with an ST Elevation Myocardial Infarction for primary PCI. Patients may receive up-front unfractionated heparin or low molecular weight heparin, but not glycoprotein IIb/IIIa inhibitors or thrombolytics. Patients will be consented prior to the diagnostic catheterization and will be randomized once the patient is deemed amenable to PCI to receive eptifibatide or no eptifibatide just prior to or at the time of primary angioplasty. Patients will be randomized in a 1:1 fashion. All patients will be assessed for the primary endpoint of ST resolution at 60 minutes post PCI and followed throughout the duration of the hospitalization and up to 30 days for secondary endpoint evaluation.
The main purpose of this research study is to try to improve the results of the standard treatment for heart attacks. Normally, heart attack patients get a fast dose and a slow dose of eptifibatide in the emergency room, shortly after arriving. This drug is usually given through a vein in the arm. However, eptifibatide can also be injected directly into the heart's blood supply just before angioplasty, a common procedure to unblock a blood vessel in the heart. This new way of giving the drug is being studying.
Coronary flow reserve is an important measure of the integrity of the coronary microcirculation. Moreover, impaired coronary flow reserve is a predictor of future cardiovascular events and poor prognosis in patients after acute myocardial infarction. After acute myocardial infarction, coronary flow reserve remains significantly reduced. A previous randomized, double-blind Placebo-controlled trial (REPAIR-AMI) demonstrated complete normalization of coronary flow reserve after intracoronary application of autologous bone marrow-derived progenitor cells (but no effect in the placebo group) in patients with ST segment elevation myocardial infarction. The current study is planned to extend these findings to patients with Non-ST segment elevation myocardial infarction, since these patients have an equally reduced outcome.
Primary objective: To demonstrate that in hyperglycemic subjects with anterior STEMI (ST Elevation Myocardial Infarction) undergoing Percutaneous Coronary Intervention (PCI), tight glycemic control using insulin glulisine and insulin glargine, i.e. Intensive Insulin Therapy (IIT), results in reducing infarct size at day 60 versus (vs) Standard Glycemic Care (SGC). Secondary objectives: To demonstrate that tight glycemic control using insulin glulisine and insulin glargine reduces markers of inflammation and improves Left Ventricular (LV) function and Cardio-Vascular (CV) outcomes from baseline values, in hyperglycemic subjects with STEMI undergoing Percutaneous Coronary Intervention (PCI).
1. Assess whether excimer laser coronary atherectomy (ELCA) before direct infarct-related artery (IRA) stenting results in improved reperfusion success in patients presenting with acute ST wave elevation myocardial infarction (STEMI) and angiographically evident thrombus. 2. Validate an ELCA technique for the treatment of STEMI, at high-volume centers experienced in the treatment of acute myocardial infarction (AMI).
Background: Experimental studies have documented the beneficial effects of the endogenously produced antioxidant, melatonin, in reducing tissue damage and limiting cardiac pathophysiology in models of experimental ischemia-reperfusion. Melatonin confers cardioprotection against ischemia-reperfusion injury most likely through its direct free radical scavenging activities and its indirect actions in stimulating antioxidant enzymes. These actions of melatonin permit it to reduce molecular damage and limit infarct size in experimental models of transient ischemia and subsequent reperfusion. Study design: The Melatonin Adjunct in the acute myocaRdial Infarction treated with Angioplasty (MARIA) trial is a prospective, randomized, double-blind, placebo-controlled, phase 2 study of the intravenous administration of melatonin. The primary efficacy end point of this study is to determine whether melatonin treatment reduces infarct size determined by cardiac magnetic resonance 5-7 days post-reperfusion. Other secondary end points will be the clinical events occurring within the first year: death, sustained ventricular arrhythmias, resuscitation from cardiac arrest, cardiogenic shock, heart failure, major bleedings , stroke, need for revascularization, recurrent ischemia, re-infarctions and rehospitalization; and changes in left ventricular ejection fraction from baseline to 4 months of follow-up. Implications: The MARIA trial tests a novel pharmacologic agent, melatonin, in patients with acute myocardial infarction and the hypothesis that it will confer cardioprotection against ischemia-reperfusion injury. If successful, the finding would support the use of melatonin in therapy of ischemic-reperfusion injury of the heart.
The purpose of this study is to discover genes that may cause Coronary Artery Disease (CAD) or Arteriovenous Malformation (AVM).
The purpose of this study is to assess whether or not inhaled nitric oxide can decrease myocardial infarction (MI) size at 48-72 hours in patients presenting with an ST segment elevation MI (STEMI) who undergo successful percutaneous coronary intervention.
The purpose of this registry is to assess and improve the process of care and health outcomes of patients presenting to the Emergency Department with chest pain suspected to be of cardiac origin. The study will identify which methods facilitate the diagnosis and risk stratification of ST elevation myocardial infarction (STEMI) or non STEMI, including patients with occult myocardial infarction (MI), and result in a shorter time to definitive diagnosis and treatment.
