Active clinical trials for "ST Elevation Myocardial Infarction"

This is a Phase 2b randomized, blinded, placebo controlled study to evaluate the efficacy, safety, PK/pharmacodynamic, and immunogenicity of repeat doses of MEDI6012 in adult participants presenting with acute STEMI (ST segment elevation myocardial infarction). The study will enrol participants presenting with acute STEMI who are planned for primary percutaneous coronary intervention (pPCI). For all participants, an end of study CMR will be performed at 10-12 weeks (70-84 days following Dose 1). A subset of participants will also undergo an index and an end of study CTA.

The goal of the study is to evaluate the effect of single administration of RPH-104 at 80 mg and 160 mg on parameters of systemic inflammation and outcomes of the disease in subjects with ST-segment elevation myocardial infarction (STEMI)

RUC-4 is a novel, promising and fast acting (5-15 minutes) αIIbβ3 receptor antagonist with a high-grade inhibition of platelet aggregation (≥80%) shortly after subcutaneous administration. This study is designed to extend the findings in CEL-01 to patients with ST-elevation myocardial Infarction (STEMI) presenting to the cardiac catheterization laboratory with planned coronary angioplasty.

This study of physiologically functional FFR in STEMI patients without direct PCI treatment will provide unique data on plaque progression and risk factors.

The purpose of the study is to clarify wether body posture during ingestion of 60mg Efient, a thrombocytic inhibitor, has influence on the time to thrombocytic inhibition. The study aims to mimic the treatment Danish patients receive when admitted to the hospital with a ST-elevation myocardial infarction since these patients are refereed to acute Percutaneous Coronary Intervention (PCI) necessitating fast and efficient thrombocytic inhibition. Current guidelines recommend the administration of Efient right before the PCI procedure, while the patient is lying down, either in the ambulance or in the operating room. We, the investigators, believe that this is suboptimal for the patient, since any sort of prolonged inhibition time will possibly worsen the patients prognosis and make the patient more prone to later clotting issues. Our hypothesis is that by making the patients ingest the tablets in a 90 degrees upright position and making them sit up for 2 minutes after ingestion, the effect of the pills will commence faster than if taken in a supine position. This will possibly lead to faster inhibition of the thrombocytes, which we believe will lead to a lower incidence of clotting issues during and after the procedure.

This is a single-center, randomized, single-blind, investigator-initiated, pharmacodynamic study with a parallel design. Patients with ST elevation myocardial infarction, undergoing primary percutaneous coronary intervention will be randomized after informed consent, in a 1:1 ratio to the following treatment groups: Group Α: Ticagrelor 180mg loading dose (LD), followed by a 90mg x2 maintenance dose (MD)starting 12±6 hours post LD, until Day 5 (5 days after randomization) Group Β: Prasugrel 60 mg LD followed by 10mg x1 MD starting 24 hours post LD, until Day 5 (5 days after randomization). Platelet reactivity assessment will be performed at randomization (Hour 0) and at 1, 2, 6, 24 hours after randomization, and on Day 5. Documentation of major adverse cardiac events (death, myocardial infarction, stroke, revascularization procedure with PCI or CABG)and serious adverse events (bleeding, other adverse events)will be performed until Day 5.

The objective of the RAPID STEMI study is to evaluate the feasibility, efficacy, and safety of a pharmacogenetic approach to anti-platelet therapy for the treatment of ST-segment elevation myocardial infarction (STEMI) patients following percutaneous coronary intervention (PCI) using point-of-care genetic testing for the CYP2C19*2, *17, and ABCB1 3435 C>T alleles.

This study will assess the safety and efficacy of intracoronary artery administered autologous bone marrow derived stem cells in subjects post ST segment elevation myocardial infarction (STEMI). This will be assessed by evaluating and comparing the autologous stem cell treatment group to the control group in terms of the occurrence of AE's, SAE's and Major Adverse Cardiac Events (MACE), by the change in myocardial perfusion (RTSS) measured quantitatively by gated single photon emission computed tomography myocardial perfusion imaging (gated SPECT MPI), and other secondary endpoints such as LVEF measured by cardiac MRI in addition to other endpoints.

The investigators will evaluate the effect of metformin therapy during 4 months in non-diabetic patients following ST-elevation myocardial infarction on left ventricular ejection fraction as measured with cardiac magnetic resonance imaging, compared to placebo.

Study objectives: To assess the effects of postconditioning on infarct size in patients with ST-elevation infarction referred to PCI. Study design: Prospective, randomized, open-label study with blinded endpoint evaluation. Included patients will be randomly allocated to postconditioning or control. Patients with symptoms of acute myocardial infarction of less than 6 hours duration fulfilling ECG criteria for primary PCI are eligible. PCI follow established routines. In postconditioning patients, additional, short (1 min), intermittent balloon occlusions will be applied after initial opening of infarct related artery. After this intervention, PCI proceeds routinely with stent implantation. In the control group, stent implantation after initial opening proceeds as usual. Primary endpoint is final infarct size, determined by MRI after 4 months. 260 patients will be included. Follow-up is 1 year. Inclusion period: 18 - 24 months. Clinical implications: Reperfusion therapy, administered as early as possible after start of symptoms, has improved the prognosis in acute ST-elevation myocardial infarction. Still, however, many patients suffer large infarctions, subsequently with an increased risk of heart failure, arrhythmias, and death. In pilot studies, mechanical postconditioning has been shown to reduce infarct size and thus potentially improve prognosis. However, the effect of postconditioning must be confirmed in larger clinical trials before implemented in routine treatment.
