Filter by:- Aim The AVOID (Air Verses Oxygen In myocardial infarction) trial is designed to determine if the withholding of routine oxygen therapy in patients with acute heart attack leads to reduced heart damage compared to the current practice of routine inhaled oxygen for all patients. - Background There is evidence supporting and refuting the current practice of providing oxygen to all patients with acute heart attack. A recent summary of clinical trials suggested that oxygen may increase the degree of heart damage during heart attack. It also highlighted that the few trials into oxygen therapy were performed before the use of modern medications and procedures to treat heart attack and that further studies were urgently needed, using contemporary practices. - Design A total of 334 patients will participate in this randomized controlled trial. Patients in this study will receive the best current management and care for their condition. Patients will be randomized to routine pre-hospital care with oxygen therapy vs pre-hospital care without oxygen therapy. Patients will then receive standard hospital care, aside from allocated oxygen or no oxygen therapy. The primary outcome measure of heart damage will be investigated using routine blood tests. With additional information gathered from other aspects of routine heart care including coronary angiogram, electrocardiograms and complications of hospital stay. Patients will be followed up at 6 months to determine any longer term effects of treatment.
Current antiplatelet therapy in acute coronary syndrome have a focus on the dual antiplatelet therapy including aspirin and clopidogrel. However, the patient's drug resistance of aspirin and clopidogrel is the important cause of poor clinical prognosis. Therefore, recently, clinical research about the triple antiplatelet therapy including cilostazol is actively conducted. But, clinical research about triple antiplatelet therapy for acute myocardial infarction is inadequate situation, and the ideal duration of triple antiplatelet therapy has been actively discussed. Therefore, we try to evaluate the clinical outcomes of triple antiplatelet therapy in acute myocardial infarction patients undergoing percutaneous intervention with drug eluting stent compared with dual antiplatelet therapy and investigate ideal duration of triple antiplatelet therapy through this research.
The observatory FAST MI 2010 proposes to establish a cohort of 3500 patients recruited prospectively over a period of 2 months. Patients will be followed up at 1 month and then followed annually for 10 years. Patients should have agreed to participate in the study, participation in the protocol, or refusal to participate will not affect the therapeutic approach of the physician. The study of genotypic or phenotypic characteristics will not change the therapeutic approach of health care teams.
A number of studies have suggested an association between the use of antipsychotic agents and cardiovascular mortality. However, the relationship between cardiac events and the use of antipsychotic drugs is not clear. Patients experiencing psychoses and in need for antipsychotic agents may be at a higher risk of cardiac events regardless of any effect of antipsychotic medication. Two studies have specifically investigated the association between the use of antipsychotics and the risk of cardiac events using Myocardial Infarction (MI) as an outcome measure, reporting no association and a positive association respectively. This difference in results may be explained by the use of different measures as well as study designs in both studies and because of different limitations with regard to controlling for lifestyle and medical risk factors. This study aims to assess the relationship between the risk of MI and recent exposure to antipsychotic agents by using the self-controlled case series method with which we are able to control for fixed confounders. The results of the self-controlled case series method will be compared to the results of a case-control study using the same data to compare the estimates of both methods.
The purpose of this study is to demonstrate the feasibility of pacing as a therapy to prevent adverse remodeling of the myocardium following an acute myocardial infarction (MI) in patients at highest risk for adverse myocardial remodeling.
Few reports described outcomes of complete compared with infarct related artery (IRA) only revascularization in patients with ST elevation myocardial infarction (STEMI) and multivessel coronary disease (CAD). The purpose of this study is to determine outcome (death, myocardial infarction, target vessel failure) of 180 consecutive patients with STEMI and multivessel CAD undergoing primary angioplasty. Before the first angioplasty patients are randomized to 2 different strategies: 1) culprit vessel angioplasty only, 2) staged revascularization.
The present study was designed to investigate whether the thrombus aspiration using Export Aspiration Catheter (Medtronic Corporation, California, USA) during primary percutaneous coronary intervention (PCI) in acute myocardial infarction improve clinical outcomes.
The primary hypothesis of this study is that circulating endothelial cells (CECs) harbor key genetic and structural characteristics predisposing individuals to acute atherosclerotic plaque rupture and heart attack.
Randomized comparison of two different anticoagulation strategies: prasugrel plus bivalirudin versus clopidogrel plus heparin in patients with acute myocardial infarction undergoing emergency catheterization and coronary intervention.
This study will provide follow-up information and care of patients who have undergone autologous intracoronary bone marrow cell administration at our institution. Patients are monitored for their response to treatment, progression of heart failure and coronary artery disease, and potential later occurring effects of the administered bone marrow cells. Patients are eligible for this follow-up study if they have received their first intracoronary bone marrow cell administration for the treatment of cardiac disease at our institution from 2001 ongoing. Participants are generally seen in the clinic at 12 months and 5 years after cell administration, in the meantime regular yearly telephone contacts are performed until 10 years after cell transplantation. The detailed description contains the planned procedures that are performed during the clinical visits and, if necessary, at additional contacts.
