Filter by:The trial has the following primary objective: To compare the safety and effectiveness of primary acute MI intervention with ABT 578-eluting balloon expandable stent (Medtronic, Minneapolis, MN) vs. sirolimus-eluting balloon expandable stent (Cordis Johnson & Johnson, Warren, New Jersey) vs. paclitaxel-eluting stent (Taxus Liberte, Boston Scientific).
The purpose of this study is to determine cell therapy efficacy in patients with ST elevation acute myocardial infarction (STEMI)
The aim of our study was to demonstrate that, during a percutaneous coronary intervention, even smaller amounts of abciximab than standard dose, injected locally, could achieve a rapid thrombus resolution and clinical improvement without concomitant differences in hemorrhagic complications
Cardiogenic shock is currently the main cause of death after myocardial infarction and 50% of deaths occur within the first 48 hours. To limit the extent of the myocardial necrosis is the primary objective of the treatment in this context. The symptomatic treatment of the ventricular failure alone does not allow a reduction of mortality. The immediate prognosis is not significantly improved by the current standard of care, including early revascularisation and intra-aortic balloon counterpulsation. In order to improve the immediate prognosis, it seems necessary to limit the irreversible myocardial lesions and the systemic inflammatory response induced by an extended myocardial infarction (complement activation, cytokines production, iNOS expression, etc.). These objectives may be reached by a more extended utilization and availability of circulatory assistance methods. The investigators propose to compare, in a randomised multicenter study, two treatments of the myocardial infarction with cardiogenic shock among 44 patients: Standard Treatment versus ECLS-Impella +/- standard treatment. In June 2007, an amendment replaced the device ECMO by the use of Impella intra-thoracic pump. This amendment has been approved by the Ethic Committee on July 7, 2007. In March 2009, a new amendment has been approved by the EC. This amendment allowed to revise the number of patients to enroll (reduced to 44) and this lead us to modify also the primary endpoint : variation of BNP levels between H0 and H24 (H0 defined as the nearest value of BNP level obtained before the randomization).Showing a more important BNP levels decrease in the experimental group compared to standard treatment group, the investigators obtain an indirect argument to show a superior efficacy of the tested strategy.
This trial was performed to evaluate the safety and the efficacy of G-CSF based stem cell therapy in patients with AMI. MAGIC Cell-1 trial enrolled patients with acute and old myocardial infarction, and had two groups of cell infusion, and G-CSF alone. MAGIC Cell-2 trial enrolled patients with acute myocardial infarction presented within 12 hours after onset of chest pain who underwent successful primary PCI. We randomized patients into the G-CSF group and the control group.
The primary objective of this study is to demonstrate that the efficacy of cangrelor is superior, or at least non-inferior, to that of clopidogrel in subjects requiring PCI.
This is a research study to evaluate the electrical properties of heart tissue. The purpose of this study is to determine the impedance (electrical resistance) of different tissues on the outer surface of the heart. This may be important for distinguishing scarred heart muscle from fat that can be seen on the surface of the heart. This information may eventually be utilized in patients that undergo a procedure (called catheter ablation) for the treatment of life-threatening heart rhythms. Investigators expect a detectable difference between the impedance of normal and infarcted myocardium (approximately 50 ohms).
General objective: To compare the efficacy and safety of primary angioplasty(PA) with that of thrombolytic therapy (TT) for the treatment of AMI in patients >=75 years old with ST-segment elevation or LBBB AMI <6 hours of evolution without contraindications for TT. Hypothesis: The therapeutical strategy based on PA is superior to that based initially on TT in patients >=75 years old with AMI. Participating Centers: 27 Spanish hospitals performing >50 PA/year. Primary Endpoint (PE): Incidence of the aggregate of death of any cause, reinfarction or disabling stroke at 30 days. There are also 7 secondary endpoints (SE). Procedure: Diagnosis of inclusion/exclusion criteria --> Centralized randomization --> Treatment allocation to 1) TT with weight adjusted TNK + unfractionated heparin or 2) PA within 120 minutes. Estimated Sample size and recruitment time: 570 patients in 19 months. Follow-up: Blinded evaluation of events (PROBE regulations) specified in PE and SE at 30 days and 12 months. Quality control: 100% variable and follow-up review by external CRO. Safety Committee and Event Adjudication Committee formed by experts not participating in the study.
This study is being done to determine the effects (good and bad) of intravenous infusion of a human brain natriuretic peptide (BNP), Natrecor (nesiritide), a hormone produced by the heart in persons who have just suffered a heart attack. The human BNP, Natrecor (nesiritide) has been approved by the United States Food and Drug Administration (FDA) to be given intravenously for the management of acute heart failure. It is unknown if human BNP may have good effects on the pumping function of the heart after a heart attack.
Coronary heart disease is the single leading cause of death in the United States. In 2000, it was implicated in 681,000 deaths (1 in every 5 deaths). Myocardial infarction (MI) is the major cause of death in patients dying of coronary heart disease, with an estimated incidence of 1.1 million new and recurrent cases per year. It is well established that reperfusion is the most successful treatment for salvaging myocardium during acute infarction. However, despite such treatment, a substantial number of patients still remain at risk of developing large infarcts, with reduced left ventricular function and increased mortality. Therefore, adjunctive therapies that are designed to reduce ischemic metabolism and cellular injury pending successful reperfusion, or to protect myocytes against the undesired effects of reperfusion ("reperfusion injury"), should be beneficial in limiting infarct size. Mild hypothermia is one such potential therapy. This study has been designed to evaluate whether the adjunctive use of mild hypothermia further reduces the extent of heart damage caused by a heart attack.
