High-sensitivity Troponin T in Acute Myocardial Infarction After Cardiac Valvular Surgery

A measurable degree of heart muscle tissue injury is expected in patients undergoing heart valvular surgery. The level of this injury can be measured by cardiac biomarkers in blood samples. Those biomarkers are used to diagnose an acute myocardial infarction. Postoperative myocardial infarction (MI) is a frequent and important complication after cardiac surgery with high morbidity and mortality. Therefore it is very important to recognize any cardiac event in patients who unde...

Clinical and Economic Outcomes of High Sensitivity Troponin for no ST Elevation Myocardial Infarction in Patients With Chest Pain in Emergency Departments in Italy-An Observational Study

Myocardial infarction is one of the leading causes of death and disability worldwide. In addition to standard diagnostic methods, it has been shown that high-sensitivity cardiac troponin assays allow greater sensitivity in the diagnosis of myocardial infarction and assume a central role for both exclusion ("rule out") and confirmation ("rule in") of acute myocardial infarction , while allowing to reduce the time interval between ER admission and presumptive diagnosis. Co...

One-hour Troponin in a Low-prevalence Population of Acute Coronary Syndrome

This study evaluates if the 1-hour rule-in/rule-out algorithm for a high-sensitivity cardiac troponin T (hs-cTnT) is safe and effective in patients with a lower pretest probability of an acute myocardial infarction (MI). During this study troponins will be collected at 0-, 1- and 4/6-hours, where absolute changes in the values will decide whether the patient need hospitalization or not. Can the time interval to the second troponin test be reduced by using an 1-hour high-sensiti...

Variations of High Sensitivity Troponin T in Neonates

Troponin T-us is a cardiac marker for myocardial infarction. Its use in neonates is increasing, yet normal values are still to be determined for the latest generation of tests, such as High sensitivity cardiac troponin T test. This study is an observational study designed to determine biological normal values of High sensitivity cardiac troponin T test (troponin T -us) in newborns.

High-Sensitivity Cardiac Troponin On Presentation to Rule Out Myocardial Infarction

Patients with suspected acute coronary syndrome account for a tenth of all presentations to the Emergency Department and up to 40 per cent of unplanned hospital admissions. The majority of patients do not have a heart attack (myocardial infarction), and may be safely discharged from the Emergency Department. The investigators propose to evaluate whether the use of the HighSTEACS pathway in patients with suspected acute coronary syndrome reduces length of stay and allows more p...

COmparisoN of High-sensitivity Cardiac TRoponin I and T ASsays Trial

Background: Comparative studies addressing the analytical and clinical performance of hs-cTnI and hs-cTnT assays for the diagnosis of acute myocardial injury and myocardial infarction in consecutive patients presenting to a United States (US) emergency department are lacking. Study objective: Compare the analytical and clinical performance of hs-cTnI and hs-cTnT assays for the diagnosis of acute myocardial injury and myocardial infarction in patients presenting to the emergenc...

Biomarkers for Postoperative Myocardial Infarction in Cardiac Surgery.

Myocardial infarction and subsequent myocardial injury after cardiac surgery occurs in 7-15% of patients undergoing cardiac surgery and is associated with an increased length of stay, and reduced short- and long-term survival. Cardiac troponin is considered to be a cornerstone in the diagnosis of a myocardial infarction. Heart-type Fatty Acid-Binding Protein (H-FABP) is a new sensitive biomarker for myocardial injury. The effectiveness of using the combination of H-FABP with Tr...

Rapid Use of High-sensitive Cardiac Troponin I for ruling-in and Ruling-out of Acute Myocardial Infarction

Early rule-in or rule-out of myocardial infarction (MI) is essential in patients presenting to the Emergency Department with chest pain. Recently, the European Society of Cardiology has suggested an accelerated 0h/1h algorithm to rule-in or rule-out MI as a valid alternative to the standard 0h/3h approach. So far, the 0h/1h algorithm has only been validated for certain high-sensitive Troponin assays. Moreover, it is unknown if MI can be ruled-out by measuring hs-cTn already at ...

Corticosteroids and Myocardial Injury in CAP (COLOSSEUM TRIAL)

Community-acquired pneumonia (CAP) is often complicated by elevation of cardiac troponin, a marker of myocardial injury, that can be isolated or associated to myocardial infarction (MI). A retrospective study showed that corticosteroid treatment lowers incidence of MI during the hospital-stay. The aim of this clinical trial is to examine whether in-hospital treatment with iv methylprednisolone (20 mg b.i.d) may reduce myocardial injury, as assessed by serum high-sensitiv...

Study on High-sensitivity Troponin 0h/1h for Rapid Diagnosis of Non-ST-segment Elevation Myocardial Infarction in the Chinese Population

The purpose of the study is to establish a high-sensitivity troponin 0h/1h process for the diagnosis of patients suspected of NSTEMI for the Chinese population, obtain the inclusion and exclusion criteria for diagnosis of these patients and compare the new process with the existing diagnosing methods and processes, including the 3h and 6h processes more extensively used at present and the ECG combined with troponin diagnosis, so as to explore a confirmation model suitable for t...

Evaluation of Serial Troponin and Cardiac Multimarkers at the Point of Care in the Emergency Department

This is a multi-center study to assess the diagnostic accuracy of the Troponin I assay in the Biosite Triage Cardio3 Panel at the point-of-care (POC) in adults presenting to the emergency department with possible acute myocardial infarction (AMI).

Troponin Elevation After Major Noncardiac Surgery 2

Major adverse cardiac events (MACE) are a leading cause of mortality in patients undergoing noncardiac surgery. Patients with perioperative myocardial injury (PMI), defined as either myocardial infarction and lower elevations in cardiac troponin, are also at substantially increased risk of additional cardiac and noncardiac complications. Accordingly, it is plausible to assume that PMI negatively affects quality of life in terms of disability. The aim of this study is to investi...

Copeptin Registry (proCORE) Biomarkers in Cardiology (BIC)-19

Registry of an interventional Study-proved Strategy (BIC-8) using Copeptin and Troponin for the Early Rule-Out of Acute Myocardial Infarction (AMI) in Patients with Suspected Acute Coronary Syndrome (ACS) and a low-to intermediate risk profile.

Accelerated Rule Out of 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 r...

Effectiveness and Safety of a Clinical Assessment and 0h/1h Troponin Rule-Out Protocol

Chest pain is a common presenting complaint at the Emergency Department (ED). Many of these patients undergo lengthy assessments in the ED or are admitted which contributes to ED and hospital crowding as well as a substantial health care burden. The now commonly used high-sensitivity cardiac troponin assays enable faster rule-out of acute myocardial infarction (AMI). The European Society of Cardiology (ESC) recommend the use of a 0h/1h high-sensitivity cardiac troponin T (hs-cT...

Distribution of Highly Sensitive Troponin in the Critically Unwell & Associated Mortality

The current diagnostic criteria for a heart attack require evaluation of a patient's symptoms and ECG but importantly a blood test called troponin. With advancing technology this test has become more sensitive and is now called a high sensitivity troponin. This is a very effective way of rapidly excluding a heart attack if the test is negative. However there are a number of causes of a raised high sensitivity other than a heart attack, particularly critical illness states. In t...

Evaluating the Role of Coronary Artery Disease to Resolve the Diagnosis of Type 2 Myocardial Infarction

Myocardial injury is common in patients without acute coronary syndrome, and therefore international guidelines propose a classification of patients with myocardial infarction by aetiology. This differentiates between myocardial infarction due to plaque rupture (type 1) and myocardial oxygen supply-demand imbalance (type 2) in other acute illnesses. However, these guidelines have not been widely adopted as the diagnostic criteria for type 2 myocardial infarction are not clearly...

Induced Myocardial Ischemia: a Serial Troponin T and Troponin I Measurements

Background Troponin are proteins found in the cardiomyocyte and are a cornerstone in the diagnoses of acute myocardial infarction. Troponin is released to the bloodstream as a result of an cardiomyocyte injury. Troponin is frequently assessed in hospital care for patients with chest pain and dyspnea. Guidelines recommend troponin assessment at admission and repeated at 3 to 6 hours, depending on the assay. High-sensitivity assays measure concentrations that are ten-times ...

IRIS : Use of Implantable Defibrillator in High-Risk Patients Early After Acute Myocardial Infarction

Of the patients who survive hospitalization after an acute myocardial infarction, ca. 10% die of sudden cardiac death in the following 2 years. The prognosis appears not improved by medication with antiarrhythmics (class I/III). A positive effect of beta-blockers (Metoprolol CR/Zok) on total mortality after myocardial infarction in patients with heart failure is well established. On the other hand, an implantable defibrillator (ICD) proved to be superior to medication when used...

A Project to Improve the Diagnosis and Prognosis of Myocardial Injury Associated to Non Cardiac Surgery

Major adverse cardiovascular events are the leading cause of perioperative morbimortality in non-cardiac surgery. Perioperative myocardial infarction is usually asymptomatic, with a mortality around 10-12%. Myocardial Injury in Noncardiac Surgery (MINS), is defined as a myocardial injury that provokes a troponin increase due to myocardial ischemia. MINS is a predictor of morbimortality at short term and at long term. The aim of the study is to improve the diagnosis of m...

Myocardial Injury Related to Coronary Angiography in the Era of High-sensitivity Cardiac Troponin I

A prospective study aiming to analyse the relation between different variables and high sensitivity troponin I (hsTnI) elevation within a group of patients undergoing a coronary angiography with or without subsequent percutaneous coronary intervention.

Reliability of Cardiac Troponins for the Diagnosis of Myocardial Infarction in the Presence of Skeletal Muscle Disease

Visits to the emergency department (ED) for chest pain are extremely common and require a safe, rapid and efficacious treatment algorithm to exclude a possible AMI. These diagnostic algorithms are partly based on an important laboratory value, which showed growing utility in the diagnostic and prognostic of many cardiovascular diseases in the last years : cardiac troponin. However, some patients with muscle disease often present with unexplained elevated high-sensitive c...

Sensitive Troponin I in Out-of-hospital Cardiac Arrest

Troponin is a major diagnostic criterion of acute myocardial infarction (AMI) which confirms myocardial damage and necrosis. In out-of-hospital cardiac arrest (OHCA) patients its dynamics and diagnostic value is often controversial and has not been well described. Most of prior studies were retrospective, using first generation troponin assays and assessing only admission troponin. The aim of this work is to correlate dynamics of sensitive troponin I with urgent coronary angiog...

Strain-Encoded Magnetic Resonance Imaging in Acute Myocardial Infarction

The aim of the study was therefore to evaluate whether myocardial deformation imaging performed by SENC allows for quantification of regional left ventricular function and is related to transmurality states of infarcted tissue in patients with acute myocardial infarction (AMI).

VITROS Immunodiagnostic Products hs Troponin I

The purpose of this clinical study is to collect data to substantiate the use of the VITROS hs Troponin I test as an aid in the diagnosis of myocardial infarction (MI). The test is further indicated for risk stratification of mortality, myocardial infarction or coronary revascularization in patients with acute coronary syndrome.
