Filter by:The purpose of the Study is to determine whether early treatment with pravastatin can reduce adverse cardiac events in patients with acute myocardial infarction and minimally to mildly elevated serum Low Density Lipoprotein -Cholesterol (LDL-C) levels.
This study will assess whether an implantable defibrillator will increase the likelihood of survival in patients who have had a heart attack, have abnormal test results from a 24 hour heart monitor, and who have low normal heart function.
The purpose of the study is to compare two surgical strategies for coronary artery bypass grafting with respect to the occurrence of cerebral infarctions made visible by magnetic resonance imaging
Primary Objective The primary objective of this study is to evaluate the safety and feasibility of transendocardial injection using the Cordis Biosense NogaStarTM Mapping Catheter with the Biosense MyostarTM Left Ventricular Injection Catheter of 25 M, 75 M, and 150 M allogeneic mesenchymal precursor cells (MPCs) in subjects with AMI. SecondaryObjective The secondary objectives are to explore functional efficacy for subsequent study design, as well as late-term dose related tolerance, by: - Evaluating the effect of allogeneic MPCs on exploratory efficacy endpoints related to cardiac function on Days 90, 180, and 1 year - Evaluating the change from baseline in the Medical Outcome Study Short Form (SF-36), Kansas City Cardiomyopathy Questionnaire, Seattle Angina Questionnaire, and the New York Heart Association Classification at 30 days, 3 and 6 months, and 1, 2, and 3 years - Evaluating follow-up safety through Day 360 - Providing preliminary data to support dose selection for future studies
Combination use of darbepoetin and G-CSF will improve left ventricular systolic function in patients with acute myocardial infarction who receive intracoronary infusion of mobilized peripheral blood stem cell in comparison with patient who treated with conventional measures and who received intracoronary infusion of mobilized peripheral blood stem cell by G-CSF alone.
Large acute myocardial infarctions are the most frequent cause of subsequent systolic heart failure. Some evidence exists on the improvement after intracoronary administration of bone marrow cells in patients with a recente acute myocardial infarction. Although subgroup analyses suggest that patients with the largest myocardial infarctions have the largest increase in ejection fraction after intracoronary bone marrow administration, there is no published trial including only large myocardial infarctions. Therefor we sought to confirm the subgroup analyses by conducting a trial in only large first acute myocardial infarction patients.
The purpose of this study is to determine whether Coronary Computed Tomographic Angiography (CCTA) will increase patient safety by decreasing the rate of missed ACS and adverse events in patients who receive standard care plus CCTA versus standard care alone. Additional goals of the study are to determine whether CCTA can safely reduce the duration of ED visits and the number and duration of hospital admissions.
The triage of patients with suspected acute coronary syndrome in the emergency room is a time-consuming diagnostic challenge. Therefore high sensitive early markers for myocardial damage are needed for more rapidly rule out of acute myocardial infarction (AMI) - especially for the first 3 to 4 hours after onset of chest pain in AMI ("troponin-blind" period). Therefore we test the hypothesis that the use meticulous patient history and novel cardiac markers can provide a faster detection or exclusion of AMI in patients presenting with acute chest pain to the emergency department. The prospective cohort study is designed to enrol patients presenting with acute chest pain at rest within the last 12 hours to the emergency department. Several blood samples for detection of the new markers will be drawn and compared with the gold standard for the diagnosis of AMI (high-sensitivity cardiac troponin T). All patients will be contacted by telephone at 3, 12, 24 and 60 months to determine functional status, major adverse cardiac events (death, myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention), and the results of cardiac examination (stress test, coronary angiography) if performed.
We will study in a prospective randomised fashion 50 patients who will be treated by intracoronary transplantation of autologous, mononuclear bone marrow cells (BMCs) in addition to standard therapy after MI or standard therapy. After standard therapy for acute MI, 10 patients were transplanted with autologous mononuclear BMCs via a balloon catheter placed into the infarct-related artery during balloon dilatation (percutaneous transluminal coronary angioplasty). Another 10 patients with acute MI were treated by standard therapy alone. After
Eighty-six patients with heart attacks will be identified at our hospital. Post heart attack we will assess heart function, blood flow to the heart, and heart cell function. We will assess these parameters using nuclear cardiology scans that are used in everyday cardiology practice. The patients will then be divided into 2 groups. One group will receive a medication called G-CSF and the other group will receive a placebo. We will give this drug (1-2ml) for 4 days beneath the skin. We will take the patients blood during this time and measure how the drug affected their blood. The patients will all have the nuclear cardiology tests again in 6 weeks and 6 months to see how their heart is functioning. As well, they will have a six month angiogram. All the patients will otherwise receive optimal care from their Cardiologist. They will be seen at 6, 12, 24, and 52 weeks to assess them clinically. This study will test the effects of G-CSF on the heart function of patients who have had a heart attack. It is a medication that that has been shown in an animal model to improve heart function after a heart attack. It is a medication that has been used for many years to treat patients with cancers and to increase the number of cells donated by healthy bone marrow donors. It has no serious side effects. It works by increasing the number of a person’s own stem cells in the blood. Stem cells are special cells that are present in our bodies that have the ability to form new cells. It had been thought that the heart could not make new cells after it has been damaged. Other investigators have shown that this might not be the case. It is now thought that after an injury, stem cells from the bone marrow can transform into cells of the injured tissue. Therefore, we are trying to increase the number of stem cells in the circulation with G-CSF so as to increase repair in the heart after it has been damaged. This strategy has never been tried in human beings and if successful could greatly reduce death and suffering from heart disease.
