Active clinical trials for "Myocardial Infarction"

Every year > 50.000 people in Denmark are hospitalized with a suspected acute myocardial infarction (AMI). The majority has other explanations of their chest discomfort and most are discharged again without any initiation of treatment. Still, the suspicion dictates acute ambulance deployment, hospital admission to a highly specialized cardiac unit, cardiac surveillance and cardiac troponin blood sampling. The novel biomarker copeptin, a byproduct of vasopressin production, is released immediately from the pituitary gland as part of the hormonal response to AMI. Peak concentrations are reached within the first hour. Previous studies have suggested the combination of copeptin and cardiac troponin for fast and reliable rule out of AMI. However, the blood sampling should be performed as soon as possible after symptom onset, preferably already during the prehospital phase. We aim, in an open randomized setting, to investigate the combined measurement of prehospital copeptin and in-hospital high sensitive cardiac Troponin T compared to the standard rule-out procedure of suspected myocardial infarction. We hypothesize that the combined measurement of prehospital copeptin and in-hospital high sensitive troponin T: Reduces admission time by 1.5 hours in patients where AMI is ruled out Reduces the time to disposition Is non-inferior compared to the standard rule-out procedure in relation to major adverse cardiovascular events. Is more cost efficient compared to standard diagnostic strategy

This is a multicenter randomized, double-blind, placebo-controlled, parallel-group, dose-ranging phase 2b study to investigate the hepatic and renal safety and tolerability of multiple dose administration of two dose levels of CSL112 compared with placebo in subjects with acute myocardial infarction (AMI).

The purpose of this study is to assess the safety and tolerability of human allogeneic mesenchymal bone marrow cells (aMBMC) administered intravenously to subjects with ST Segment Elevation Myocardial Infarction (STEMI).

Use of MRI and DWI to diagnose cardiac scarring after heart attack.

The purpose of this study is to determine if a device known as the TandemHeart® System (TandemHeart) can help limit heart damage and reduce serious complications after a certain type of heart attack (acute ST elevation anterior wall myocardial infarction [STEMI]) by evaluating the use of the TandemHeart system prior to a procedure called percutaneous coronary intervention (PCI)

This study aims at evaluating the diagnostic efficacy of Gadobutrol versus Gadobenate dimeglumine at similar dose of 0.1mmol/kg for assessment of myocardial infarction by delayed enhancement cardiac Magnetic Resonance Imaging

Patients submitted to noncardiac surgeries are at increased risk of serious cardiovascular complications. Statins have shown to lower cholesterol levels and reduce cardiovascular events in other scenarios. The objective of this study is to explore the effects of atorvastatin, as compared with placebo, on the 30-day risk of a composite of death, nonfatal Myocardial Injury after Noncardiac Surgery (MINS), or stroke among patients who undergo noncardiac surgery.

The purpose of this study is to compare aspirin + clopidogrel with aspirin alone as antithrombotic treatment following transcatheter aortic valve implantation (TAVI) for the prevention of major ischemic events [myocardial infarction (MI), ischemic stroke] or death without increasing the risk of major bleeding events.

Approximately half of patients with acute chest pain, a very common reason for emergency department visits worldwide, have a cardiac cause. Two-thirds of patients with a cardiac cause are eventually diagnosed with a so-called non-ST-elevation myocardial infarction. The diagnosis of non-ST-elevation myocardial infarction is based on a combination of symptoms, electrocardiographic changes, and increased serum cardiac specific biomarkers (high-sensitive troponin T). Although being very sensitive of myocardial injury, increased high-sensitive troponin T levels are not specific for myocardial infarction. Invasive coronary angiography is still the reference standard for coronary imaging in suspected non-ST-elevation myocardial infarction. This study investigates whether non-invasive imaging early in the diagnostic process (computed tomography angiography (CTA) or cardiovascular magnetic resonance imaging (CMR)) can prevent unnecessary invasive coronary angiography. For this, patients will be randomly assigned to either one of three strategies: 1) routine clinical care and computed tomography angiography early in the diagnostic process, 2) routine clinical care and cardiovascular magnetic resonance imaging early in the diagnostic process, or 3) routine clinical care without non-invasive imaging early in the diagnostic process.

The purpose of this study is to determine the efficacy of intravenous human beta natriuretic peptide (BNP, Nesiritide) as compared to placebo to prevent adverse post acute myocardial infarction left ventricular remodeling.
