The interpretation of troponin elevation whitout a typical myocardial infarction symptomatology is a daily challenge in the acute care setting. Using current investigative techniques, doctors navigate between the five types of myocardial infarction established by the Fourth Universal Definition. However, due to the development of ultrasensitive troponin assays, the myocardial injury without ischemia, acute or chronic, is became a more common entity. The purpose of this article is to describe the situations without typical symptoms of myocardial ischemia and their mechanisms to better differentiate them.

Traditionally, elevated troponin concentrations were synonymous with myocardial infarction. But with improvements in troponin assays, elevated concentrations without overt myocardial ischemia are now ...
Troponin is an integral component of the evaluation for acute coronary syndrome (ACS) and occlusion myocardial infarction (OMI). However, troponin may be elevated in conditions other than OMI.
Data regarding high-sensitivity troponin concentrations in patients presenting to the emergency department with symptoms suggestive of myocardial infarction may be useful in determining the probabilit...
Cardiac troponins are the prefered cardial biomarker in the diagnosis of acute myocardial infarction. Because they are detectable by myocardial cell damage, no matter what pathophysiology, the inte...
The significant association of myocardial ischemia with elevated QT interval variability (QTV) has been reported in myocardial infarction (MI) patients. However, the influence of the time course of MI...
The rising number of patients with chest pain without myocardial infarction has made accurate diagnosis important. Unnecessary invasive coronary angiographies are increasingly prevalent. T...
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 ...
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...
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 Coronar...
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 myoca...
A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).
A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).
MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.
MYOCARDIAL INFARCTION in which the inferior wall of the heart is involved. It is often caused by occlusion of the right coronary artery.
Laceration or tearing of cardiac tissues appearing after MYOCARDIAL INFARCTION.
Immunoassay - ELISA
Immunoassays are quick and accurate tests to detect specific molecules. Immunoassays rely on an antibody to bind to the specific structure of a molecule. Antibodies are proteins generated by animals in response to the invasion of a foreign molecule (anti...
