Filter by:This study will evaluate volunteers 18 years of age and older to see if they qualify for one of NHLBI s research studies. Tests include the following: - General medical evaluation, which may include blood tests, chest x-ray, electrocardiogram (ECG) and echocardiogram (heart ultrasound). - Other tests as appropriate, such as magnetic resonance imaging (MRI), cardiac computed tomography (CT scan of the heart), nuclear stress test and echocardiography stress test. - X-ray contrast studies of the heart and blood vessels. (These may be excluded in patients with kidney risk factors.)
Distal embolization can occur during coronary angioplasty performed in the acute phase of myocardial infarction and is associated with poor long-term outcome. We hypothesize that the use of a system allowing thrombus aspiration before angioplasty and stent implantation will limit infarct size and its severity.
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)
Citicoline is a safe drug approved in some countries for the treatment of acute ischemic stroke. The drug has shown some evidence of efficacy in a pooled analysis, based on four clinical trials done in USA with oral citicoline.The purpose of the study is confirm the results obtained in the pooled analysis, that is, evidence of efficacy in the treatment of acute ischemic stroke
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).
