Troponin is a protein released when the heart muscle is damaged. Therefore, this is considered a highly accurate method of diagnosing myocardial infarction. Currently, high sensitive troponin tests are recommended to replace the previous troponin test.

Cardiac markers are valuable in diagnosing myocardial infarction. Cardiac markers in the emergency department also help differentiate from other myocardial injuries. The following article will discuss cardiac markers used in the emergency department for diagnosis and prognosis.

Troponin is a protein found in the heart and skeletal muscles that helps control the contraction of the heart. Troponin elevation is caused by two groups of factors: myocardial infarction and non-myocardial infarction. Among them, increased troponin in acute pulmonary embolism is one of the familiar non-myocardial infarction causes.

Myocardial infarction is the death of heart muscle cells due to ischemia. Diagnosis of myocardial infarction is based on clinical symptoms, electrocardiogram, cardiac imaging, and troponin. Troponin is the most valuable biomarker to date for the diagnosis of myocardial infarction
