Active clinical trials for "Myocardial Infarction"

This study aims at evaluating, in a proof of concept approach, the outcome of patients presenting with acute ST-elevation myocardial infarction within 3 hours of symptom onset in either a pre-hospital setting or community hospital emergency room without a PCI facility. Following randomisation a strategy of early tenecteplase and additional antiplatelet and antithrombin therapy followed by catheterisation within 6-24 hours with timely coronary intervention as appropriate (or by rescue coronary intervention if required) in Group A will be compared to primary PCI performed according to local standards in Group B. The study is exploratory in nature and will examine this medical question. The efficacy and safety endpoints as well as mixed (efficacy and safety) composite endpoints up to or before 30 days following randomisation will be evaluated. All clinical endpoints of main interest will be assessed as single or composite endpoints for evaluation of the trial objective. All statistical tests are of exploratory nature based on descriptive p-values for formal statistical hypotheses generation.

A three months, double-blind, randomised, parallel-group study evaluating the efficacy of sitagliptin (Januvia™) versus placebo on beta-cell function in patients with newly detected glucose abnormalities and acute myocardial infarction or unstable angina pectoris. Primary endpoint Improvement in beta-cell function measured by means of the insulinogenic index (ΔI30/ΔG30) obtained from an oral glucose tolerance test (OGTT). Secondary endpoints Improvement of glucose tolerance by means of an OGTT Improvement in endothelial function Improvement in incretin-independent beta-cell function measured as the Acute Insulin Response (ΔAIRG) during an intravenous glucose tolerance test

The purpose of this study is to determine if escalating doses of AMI MultiStem® delivered by catheter can safely be given to patients that have had a recent heart attack treated with stent implantation.

The purpose of this study is to evaluate the efficacy of three different vasodilators including diltiazem, verapamil and nitroglycerin for reversal of no-reflow/slow-flow during direct percutaneous coronary intervention for acute myocardial infarction.

This is an intervention study focusing on both medical and nursing questions. The study is a joint project between the Ambulance services at four cities in West Sweden and Knowledge and research centre, PreHospen at University of Borås. The aim is to prove the importance of a caring relation between a patient and a caregiver in cases when a caregiver treats a patient with benzodiazepines (Midazolam). The overall aim is to show that knowledge and skills in both caring science and medicine can be applied at the same time in order to relieve pain and anxiety in acute myocardial disease. The nursing intervention involves a professional development course for caregivers. The course is expected to deepen the caregivers' knowledge about the encounter with patients as well as cardiovascular treatment. Following questions are formulated: A. What are the effects regarding relieving pain and anxiety in acute myocardial disease? B. What are the effects regarding circulatory influence? C. What are the effects regarding patients' experiences of the ambulance services? D. What are the effects regarding number of care days in relation to acute myocardial disease? E. What are the effects of patients' disease complications?

Although statin prior to PCI has favorable effects in stable angina and ACS except ST elevation MI (STEMI), there have been few studies for STEMI. Celik T et al. reported in patients with STEMI that prior statin use may improve coronary blood flow after PCI in patients with AMI, possibly by its beneficial effects on microvascular function. But this study was retrospective, non-randomized study and evaluated the effects for chronic statin therapy not acute high dose effect. Therefore, the investigators investigated whether acute high-dose statin prior to primary PCI in ST segment elevation myocardial infarction can have beneficial effect or not for periprocedural period and 30 days-cardiac events.

This study is a prospective, randomized controlled, single blind, two-arm, multi center clinical evaluation. A total of 1500 patients will be enrolled in the study. Patient randomization will be to one of the two treatment arms: Everolimus arm or Non drug eluting stent arm. The objective of this study is to assess the safety and performance of the Everolimus Eluting Coronary Stent System versus a modified cobalt chromium balloon expandable stent in the setting of primary percutaneous coronary intervention for treatment of patients presenting with ST-segment elevation myocardial infarction.

The purpose of this study is to determine whether giving cardiosphere-derived stem cells (CDCs) to patients with decreased heart function and/or a large amount of damaged muscle after a heart attack is safe. CDCs are cells grown from small biopsy samples taken from the heart. Giving a patient their own CDCs is an investigational procedure that has been approved by the Food and Drug Administration for this study. In addition to determining whether this treatment is safe, the study will also examine whether it can decrease the amount of heart muscle damage and/or improve heart function after a heart attack. The amount of heart muscle damage and the function of the heart directly affects prognosis (the predicted course of the disease), and the development of heart failure and other complications some patients experience after a heart attack. By way of background, scientists and physicians believed, until just a few years ago, that heart muscle damaged after a heart attack could not be replaced. Recently, however, scientists discovered that new heart muscle can form, or be regenerated, and that this process can be enhanced (or increased) by the administration of large numbers of certain cells isolated from the heart or bone marrow. These cells can be stem cells, or cells derived from stem cells, and they may achieve their benefit by forming new heart muscle cells, becoming heart muscle cells themselves, or releasing substances which increase the ability of already existing stem cells to form new heart muscle. All of the studies conducted so far have been experimental and no cell type is approved for routine clinical care of patients with heart disease. However, studies involving bone marrow stem cells do indicate some small improvement in heart function and one large study demonstrated a decrease in clinical events in the group which received bone marrow cells. Investigators of this study decided to study CDCs because they come from a person's own body, and therefore have no foreign immune antigens which may be rejected. Since the cells come from the person's heart, they are more likely to form heart tissue. In addition, animal studies indicate no safety problems and that these cells are capable of forming heart muscle and blood vessel cells after heart attacks. The investigators are now studying whether the same is true in humans.

The aim of this study is to determine both safety and effectiveness of three different loading dose regimens of clopidogrel in patients with acute myocardial infarction undergoing primary angioplasty.

Multinational, multicentre, randomised, prospective, open, parallel group study directly comparing two glycoprotein-IIb/IIIa inhibitors, abciximab and eptifibatide, added early to standard treatment before primary PCI of STEMI patients with respect to effect on sum-ST-resolution after 60 minutes post-procedure and other measures of myocardial reperfusion
