Elevated troponin without a myocardial infarction.

Summary of "Elevated troponin without a myocardial infarction."

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.

Medical and Biotech [MESH] Definitions

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.
