Active clinical trials for "Infarction"

Administration of Ticagrelor in patients with ST elevation myocardial infarction treated with pharmacological thrombolysis

Patients presenting with large myocardial infarction and signs of persistent ischemia after successful percutaneous coronary intervention, have a poor prognosis with respect to outcome and development of heart failure in the future. The hypothesis of this study is that in patients in whom persistent ischemia is present, use of intra-aortic balloon pump will be beneficial and improve outcome.

New treatments are required to improve health outcomes in patients with ischemic heart disease. This is especially so in developing countries such as Mauritius in which optimal therapy for acute myocardial infarction may not be widely available. For example for patients presenting with a heart attack (caused by a blockage in one of the heart blood vessels) the treatment of choice would be to remove the blockage by primary percutaneous coronary intervention (PCI) using an angioplasty balloon and put a stent (a spring-like structure) to keep the artery opened. However, PCI is not widely available in Mauritius and heart attack patients are given clot-busting therapy to remove the blockage, but this is not as effective as PCI. Therefore, in this research study we investigate a new cheap treatment that may help protect the heart against damage during a heart attack, called remote ischemic conditioning (RIC), in which a blood pressure cuff is placed on the upper arm and inflated for 5 minute and deflated for 5 minutes a cycle which is repeated 4 times in total in patients presenting with a heart attack. By temporarily depriving oxygen and nutrients to the arm with the blood pressure cuff a protective signal can be relayed to the heart to reduce the amount of damage occurring during the heart attack and thereby prevent the onset of heart failure. Study hypothesis: Remote ischaemic conditioning will reduce the amount of damage occurring to the heart muscle during a heart attack..

The purpose of this study is to compare unfractionated heparin (UFH) and bivalirudin in the performance and subsequent outcomes of Primary percutaneous coronary intervention. This will be a pragmatic trial. Interventional procedures will be performed to reflect current and evolving standards, including predominant radial access. All patients will be treated with routine oral anti-platelet therapy pre-procedure. GP IIb/IIIa inhibitors will be reserved for 'bail out' treatment only.

The overall aim and primary objective is to evaluate the effects on level of depression and anxiety of an Internet-based CBT-program in depressed and/or anxious patients after a myocardial infarction (MI).

Prospective, randomized and open label trial Hypothesis Infusion of intracoronary darbepoetin-alpha at the time of reperfusion may reduce infarct size and post-infarct pathologic left ventricular remodeling in patients with ST-segment elevation myocardial infarction. Methods Randomization into control group or treatment group Treatment group : Darbepoetin-alpha 300ug intracoronary bolus infusion via over-the-wire balloon system simultaneously with first balloon inflation and conventional treatment Control group : conventional treatment Endpoints peak CK-MB & troponin levels : baseline,6h,12hr,18hr, 24hr, 36hr and 48hr MRI at baseline : infarct size, area at risk and salvaged myocardium MRI at 4 months : prevalence of pathologic left ventricle remodeling (definition: increase of end-diastolic volume index > 20% compared to baseline) safety endpoint : cardiac death, nonfatal myocardial infarction, stent thrombosis, ischemic stroke, hospital readmission with heart failure or ischemic symptom, bleeding and urgent target lesion revascularization

Although a percutaneous coronary intervention (PCI) can be used to open up the blocked artery and restore blood flow to the heart muscle after myocardial infarction, there may be a significant amount of heart tissue that has been irreversibly damaged. Recent studies have shown that adult stem cells from bone marrow may be able to improve heart function and prevent from heart remodeling due to heart failure. This study will evaluate the safety and effectiveness of using adult bone marrow derived stem cells for improving heart function in MI patients with Left Anterior Descending (LAD) involvement.

One of the important reasons for human dying is Ischemic heart disease (IHD). The most reason is coronary artery disease. Beside morbidity, IHD induce myocardial infarction and necrosis which due to congestive heart failure. One therapeutic method is cellular cardiomyoplasty, which is to produce and substitute the cardiac cells with stem cell transplantation. Cell therapy is a potential therapeutic method to prevent ventricular remodeling after acute myocardial infarction. Human and animal studies have shown that stem cell trans plantation to myocardial infarcted zone can improve heart contractile function. The aim of this study is to comparison the effects of BM-derived AC133 and MNC implantation in patients with myocardial infarction.

The aim of this study was to measure the effect of moderate and intensive lipid-lowering treatment with rosuvastatin on the carotid intima-media thickness (CIMT) as a surrogate marker of cardiovascular risk.

In patients with ST elevation myocardial infarction (STEMI)treated with primary percutaneous coronary intervention (PPCI) a subset with low risk for late complications can be identified. Early discharge (<72h) of these patients can compromise initiation of prophylaxis, information and other investigations. The researchers want to investigate prospectively whether early discharge compared to regular care have comparable patient centered outcomes at 30 days follow-up.
