Filter by:Outcome of patients with myocardial infarction complicated with cardiogenic shock is very poor. Although early mechanical revascularization has been demonstrated superior to conservative medical treatment, mortality range remains about 45-60%. Some medical registries have showed further therapeutic benefit by administration of glycoprotein (GP) IIb/IIIa inhibitors during PCI in patients with cardiogenic shock. However, there is no randomized study that supports this therapeutic strategy in these high risk patients. Hypothesis: GP IIb/IIIa inhibitors improve angiographic (TIMI-flow), echocardiographic (LV function) and clinical (combined end-point) outcomes in patients with myocardial infarction complicated with cardiogenic shock. Study design: Open "pseudorandomized" multicenter, phase IV clinical trial. Anticipated findings: The investigators anticipate to document better angiographic, echocardiographic and clinical outcome after upfront abciximab administration in comparison to standard periprocedural therapy in patients undergoing PCI for cardiogenic shock. This would be the first randomized clinical trial that could support this therapeutic strategy.
The purpose of this study is to evaluate the efficacy and safety of a left ventricular assist device in comparison to a standard treatment with an intraaortic balloon pump (IABP) in patients with cardiogenic shock due to left ventricular failure following an acute coronary syndrome (myocardial infarction).
It is possible to measure skeletal muscle tissue oxygenation (StO2) using near infrared spectroscopy(NIRS). It is performed non invasively. We want to compare usually used invasive methods for assessing adequacy of flow to StO2 in critically ill. Aim is to faster and non invasively estimate adequacy of flow to make therapeutic algorithms efficient.
The purpose of this study is to determine the safety and efficacy of a 24 hour infusion with levosimendan in patients with acute myocardial infarction and heart failure after acute percutaneous coronary intervention (PCI) treatment.
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.
Extracorporeal membrane oxygenation (ECMO) is a means of artificially performing the function of the human lung and/or heart outside the body. Its use is escalating in a wide range of clinical settings in the adult population without evidence or guidelines to support this practice. This study involves a nationwide questionnaire which has two components. The initial pilot survey will attempt to identify all institutions currently practicing ECMO or those intending to do so in the future, and are willing to participate in prospective data collection. The second phase will involve a monthly survey of these centres regarding the extent of ECMO use, practice details implemented, and outcome data. It is hoped that the collection of this information will later assist in the development of guidelines for this expensive and presently unsubstantiated practice, together with the construction of appropriate training programs for staff.
Tilarginine Acetate Injection is a new type of drug that temporarily stops the body from making a bodily substance called nitric oxide. The body may produce excess nitric oxide following severe heart damage leading to shock. During a heart attack, and especially after a blocked artery causing the heart attack is reopened, a large amount of nitric oxide is released into the heart muscle and into the blood. Normally small amounts of nitric oxide are good for the heart and blood vessels. However, when released in large amounts, such as during a heart attack, it may be harmful, by adding to the damage of the heart attack and lowering the heart’s ability to pump blood to the body. It may cause blood pressure to be lowered and reduce the amount of blood flow to the body’s vital organs. This may interfere with the body’s organs being able to do their work. If Tilarginine Acetate Injection can stop extra nitric oxide from being made, the performance of the heart and blood flow to the organs may get better, which may result in the improvement of symptoms. The purpose of this study (TRIUMPH) is to investigate the safety and effectiveness of Tilarginine Acetate Injection compared to placebo (an inactive fluid that has no effect on the body but looks exactly like the medication being studied). The study will help determine whether Tilarginine Acetate Injection, by temporarily lowering the amount of nitric oxide released into the vital organs can improve blood pressure and the blood flow to the body’s organs.
The purpose of the study is to compare the efficacy of levosimendan with that of dobutamine in patients with unstable hemodynamics (shock).
To test if early revascularization, primarily with angioplasty (PTCA) or bypass surgery (CABG), reduced all-cause in-hospital mortality from cardiogenic shock compared to conventional treatment, including thrombolysis.
