Active clinical trials for "Myocardial Infarction"

This was a double-blind, randomized, placebo-controlled study that was designed to enroll a total of 225 participants with de novo anterior wall acute ST-segment elevation myocardial infarction (STEMI) due to a lesion of the left anterior descending coronary artery undergoing percutaneous coronary intervention (PCI). Eligible participants were to be enrolled and undergo revascularization of the culprit left anterior descending (LAD) coronary artery. The interventional procedure included as dose ranging assessment of intracoronary (IC) delivery of MPC or placebo infused into the stented coronary artery. This study compared two doses of MPCs and a placebo control group. Study participants were randomly assigned in 1:1:1 fashion to receive either 12.5 Million or 25 Million MPCs or placebo (saline). Initially, each group was designed to have approximately 75 patients per treatment group. The Primary Objective of the study was to determine the safety and feasibility of IC infusion of investigational MPCs in this acute STEMI population. The Primary Objective of the study was to determine the safety and feasibility of IC infusion of investigational MPCs in this acute STEMI population. Feasibility of the infusion of the investigational agent was assessed by measurement of thrombolysis in myocardial infarction (TIMI) flow and perfusion (1) immediately prior to, (2) during (after approximately 50% of total investigational agent volume infused) and (3) following the investigational agent infusion after successful PCI and stenting. There was no evidence of clinically important coronary microvascular obstruction related to infusion of the investigational agent.

The use of supplemental oxygen in the setting of suspected acute myocardial infarction (AMI) is manifested in international treatment guidelines and established in prehospital and hospital clinical routine throughout the world. However, to date there is no conclusive evidence from adequately designed and powered trials supporting this practice. Existing data is conflicting and failing to clarify the role of supplemental oxygen in AMI. The DETO2X-AMI trial is designed to shed light on this important issue.

The primary endpoint is to assess the safety and tolerability of Cenderitide (CD-NP) with the incidence of symptomatic hypotension being one of the key safety variables.

Evaluate the efficacy, Safety and Pharmacokinetics of Intravenous single injection LC28-0126 immediately before PCI (Percutaneous Coronary Intervention) in Patients with STEMI (ST-segment Elevation Myocardial Infarction)

The investigators propose to test the effectiveness of a technique that uses a modified commercially available ultrasound system used for cardiac imaging, and a commercially available ultrasound contrast agent (microbubbles) to break up the blood clots that cause heart attacks. The ultrasound and microbubbles will be applied as soon as possible to patients presenting to the emergency department, after an EKG confirms that a heart attack is ongoing. Patients who provide emergent consent will be randomized to either conventional therapy for a heart attack, or conventional therapy and ultrasound with microbubbles. The ultrasound will be applied both before and after emergent heart catheterization, in order to break up the blood clots that are not only in the artery supplying the heart muscle, but also in the small branches (capillaries) that are fed by this artery. Following the randomized treatment, patients will be followed for the development of any complications (recurrent heart attack, heart failure, or need for defibrillator placement) as well as by echo and cardiac MRI to determine how much heart muscle was salvaged by the treatment. A total of 250 patients will be enrolled and followed at two different sites. Randomization will be stratified at each study site. The initial site enrolling patients will be University of Sao Paulo Medical School. Wilson Mathias, MD, will serve as the principal investigator for this site. The other is Vrije Universiteit (VU) University Medical Center in Amsterdam, where Otto Kamp, MD, will serve as the principal investigator.

Most studies on intracoronary bone marrow mononuclear cell (BMC) transplantation for acute myocardial infarction (AMI) involve treatment 3-7 days after primary percutaneous coronary intervention (PCI); however, the optimal timing is unknown. The present study assessed the therapeutic effect at different times after ST-elevation myocardial infarction (STEMI).

Cardiovascular events are the main cause of mortality in diabetic patients ,on the other hand,during an acute myocardial infarction(AMI),hyperglycemia increases mortality and is related to different pathophysiologic processes. More important evidence regarding the effect of glycemic control on AMI patients prognosis is contradictory,and the potential benefits of dipeptidyl peptidase-4 inhibitors(DPP4-i) in this setting is unknown. The aim of this study is to assess the presence of pleiotropic effects of DPP4-i(sitagliptin or saxagliptin) and their relationship with glycemic control during in-hospital phase of AMI.

Background: Colchicine is an old well-known venerable drug routinely used in gout attacks for instance. More recnetly it is regularly use in the treatment of pericarditis. It couls exert antiiflammatory effects targeting the adverse inflammation occuring incase of acute myocardial infarction, which is involved in poor outcomes or longer stay at hospital. Endpoints: Main endpoint: AUC CRP during the initial hospital stay Secondary endpoints: Clinical: oucomes Imaging: ETT, MRI Biological: various biomarkers Method Randomized, controled, open-labbelled, comparing two parallel arms: conventionnal optimal treatment versus conventionnal optimal treatment + colchicine

The LIPSIA-Conditioning trial is an investigater initiated, randomized, single-center study that will assess the effect of different intrahospital conditioning protocols on myocardial damage assessed by MRI in patients with acute ST-elevation myocardial infarction. The following groups will be compared: Combined intrahospital pre- plus postconditioning versus Postconditioning versus Control

Objective: To evaluate short- and long-term in the STEMI patients who successfully thrombolysis with early routine and delay percutaneous coronary intervention in low-intermediate risk patients. Educational/ application advantages: To evaluate the time of early and delay PCI after received fibrinolysis had an effect to the short- and long-term clinical outcomes in low- intermediate GRACE risk score patients. No available of randomized controlled study in these group of the patients.
