Myocardial InfarctionThe general aim of this study was to assess the feasibility of treating acute myocardial infarction (AMI) by physician-directed pre-hospital thrombosis, using accelerated alteplase (Actilyse®) and a diagnostic technique involving remote electrocardiogram (ECG) acquisition by paramedics

PREdisposition Genetical in Cardiac Insufficiency = Genetic Predisposition to Heart Failure
ST Elevation (STEMI) Myocardial Infarction of Other SitesOur main goal is to create a prospective cohort of 1500 patients with a first large myocardial infarction allowing us, in a second step, to identify susceptibility genes for the progression of patients towards chronic heart failure using a candidate gene/candidate pathway approach. Our main hypothesis is that there is, for a given initial biomechanical stress (duration of the ischemic episode, size of the infarcted area, etc.), a variation in the individual susceptibility to develop left ventricular remodelling and to progress towards heart failure, and that this variation is linked to genetic variants between individuals.

Long Term Follow-up of Autologous Bone Marrow Mononuclear Cells Therapy in STEMI
Myocardial InfarctionThe benefit of current reperfusion therapies for ST-elevation myocardial infarction (STEMI) is limited by post-infarction left ventricular (LV) dysfunction. Many clinic trails showed the short term outcome of bone marrow stem cell transplantation for MI patients, but rare report of long term follow-up results. Our aim was to investigate 4 years' efficacy and LV functional improvement of autologous bone marrow mononuclear cells (BMMC) transplantation in patients with ST-elevation myocardial infarction.

Myocardial InfarctionCoronary Artery DiseaseThis study is to compare the clinical effect of CYPHER® stent and ENDEAVOR® stent in patients with acute ST elevation myocardial infarction. It also aims to analyze the current status of emergency PCI green channel (time taken from door→ hospital→ PIC sign-off→ needle→ balloon) for patients with ST elevation myocardial infarction in China.

Stem Cell Mobilization by G-CSF Post Myocardial Infarction to Promote Myocyte Repair
Myocardial InfarctionEighty-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.

Combined CABG and Stem-Cell Transplantation for Heart Failure

Acute Balloon Angioplasty vs. Traditional Early Invasive Treatment of Non-ST-Elevation Myocardial...
Myocardial InfarctionThe purpose of this study is: A) To determine whether patients with a certain type of heart attack (NSTEMI) can be reliably diagnosed in an ambulance using telemedicine. This is mandatory if NSTEMI patients in the future are to be treated with acute balloon angioplasty (primary PCI). B) To evaluate whether primary PCI compared with the current regimen of initial medical stabilization and sub-acute PCI results in reduction of infarct-size in NSTEMI-patients.

Early Initiation of Low Dose Tirofiban for PPCI in STEMI Patients.
ST Elevation Myocardial InfarctionAnti-platelet therapy is a key point of acute myocardial infarction (AMI) treatment. Nowadays, dual anti-platelet therapy based on aspirin and ADP-P2Y12 receptor inhibitor is the preferred treatment before primary percutaneous coronary intervention (PPCI). Restricted by pharmacokinetic and pharmacodynamic characteristics, ADP-P2Y12 receptor inhibitors cannot take effect immediately after oral administration. However, platelet glycoprotein Ⅱb / Ⅲa inhibitors take effect faster. Previous clinical trials indicated that combination of full dose of glycoprotein Ⅱb / Ⅲa inhibitor and dual anti-platelet therapy reduced AMI related ischemia events but increased bleeding events significantly. The high dose of glycoprotein Ⅱb / Ⅲa inhibitor may be the key factor contributing to the increased bleeding events. Therefore, this study aims to evaluate the effectiveness and security of triple anti-platelet therapy based on a small dose of glycoprotein Ⅱb / Ⅲa inhibitor, aspirin and ADP-P2Y12 receptor inhibitor in AMI patients receiving PPCI.
