Active clinical trials for "Myocardial Infarction"

Primary percutaneous coronary intervention represents the gold standard for the treatment of ST-segment-elevation acute myocardial infarction. However, periprocedural bleedings are associated with an increased risk of mortality, re-infarction, and stroke. Although the prognostic value of access site related bleeding complications is still debated, transradial approach is associated with better short-term outcomes and reduced hospital stay as compared to transfemoral approach. The investigators aimed to compare transradial approach with transfemoral approach with systematic achievement of hemostasis by the implantation of a vascular closure device in a national multicentre randomized clinical trial.

Infarct size is a major determinant of prognosis after Acute Myocardial Infarction (AMI). The investigators recently reported that cyclosporine A, when administered immediately prior to percutaneous coronary intervention (PCI), can significantly reduce infarct size in STEMI (ST Elevation acute Myocardial Infarction) patients. The objective of the present study is to determine whether cyclosporine can improve STEMI patient clinical outcome. Nine-hundred and seventy two patients with ST elevation MI will be entered into a multicentre, randomized, placebo-controlled, double-blinded study. They will receive one single injection of cyclosporine A (CicloMulsion, verum) or an equivalent volume of placebo prior to reperfusion therapy by PCI. The incidence of the combined endpoint (mortality, hospitalization for heart failure, left ventricular (LV) remodeling) will be assessed at one year and three years after treatment.

Patients experiencing a mild heart attack will receive one of two medications which thin the blood to discern which is superior.

This study will create a computer program that can be used to help dose a drug called warfarin for the prevention of blood clotting. The study will collected specific information about those patients receiving this drug and use that information to create a computer program that will predict the effects of the drug. With this prediction program in place, the investigators can perform a series of "what if I gave this amount of drug" simulations to determine the best dose of drug for that patient. Once the computer programs are developed, the investigators will test the program in patients that actually need this drug. They will also include genetic information into the prediction since it has been shown that this information can affect how well the drug works. Patients will have this genetic information determined during this study.

This study aims to evaluate the use of the chest pain choice (CPC) decision aid as a tool to facilitate discussion between the patient and his/her attending physician with regard to subsequent management plans. Patients aged 21 years and above with low-risk chest pain, as determined by the HEART score (HEART score 0-3), will be included. The investigator's hypothesis is that incorporating the Chest Pain Choice visual aid in shared decision making can help to reduce unnecessary admissions for low risk chest pain to the observation ward, as well as increase patient knowledge with regards to their own condition.

The PICSO ViPER study is a prospective single centre cohort study of the use of PICSO in patients presenting acute myocardial infarction and impaired function of the left ventricle and candidate to angioplasty the left anterior descending (LAD) coronary artery. The percutaneous coronary intervention (PCI) procedure will be undertaken in a standard fashion, in accordance with the Oxford University Hospitals NHS Trust (OUHT) departmental guidelines for PCI, and includes the use of pressure wire measurements before and after stent deployment. PICSO treatment will be added on top of the conventional treatment. The protocol will constitute of 5 main stages (that will all be performed during index angioplasty procedure). The protocol is complete at the end of the angioplasty procedure, and the patient will exit the study at this point. The five stages of the protocol are described below (for details see "Detailed Description"): Baseline PICSO treatment during pre-dilation Stenting with PICSO support Post-stent Physiology PICSO treatment during post-dilation

The purpose of this study is to compare aspirin/acetylsalicylic acid+ clopidogrel with aspirin/acetylsalicylic acid alone as antithrombotic treatment following TAVI for the prevention of major ischemic events (MI, ischemic stroke) or death without increasing the risk of major bleeding events.

This research will test the effect of mass media or mass media plus a clinic based education program will improve appropriate aspirin use for cardiovascular disease prevention. It is a group randomized design of 24 geographic areas in Minnesota with adjacent states serving as controls.

The majority of deaths after myocardial infarction occurs in patients with preserved left ventricular ejection fraction (>35%) for whom no prophylactic strategies exist. Periodic Repolarization Dynamics (PRD) and Deceleration Capacity (DC) of heart rate are autonomic risk markers that identify a new high risk group of patients with LVEF 35-50% who have the same poor prognosis as patients with LVEF ≤35%. In SMART-MI, post-infarction patients with LVEF 35-50% and abnormal PRD and/or DC will be randomly assigned to biomonitoring-guided therapy or conventional follow-up.
