High levels of troponin must be myocardial infarction?

Myocardial infarction refers to myocardial infarction. High troponin does not necessarily mean myocardial infarction.

Troponin is a special protein that exists in myocardial cells. When myocardial infarction occurs, troponin in the heart muscle will be released, resulting in an increase in its content. Therefore, troponin can be used as one of the indicators for the diagnosis of myocardial infarction. However, it should be noted that, in addition to myocardial infarction, myocarditis, heart failure, arrhythmia and other diseases may also lead to troponin elevation, so the simple occurrence of this index elevation is not necessarily myocardial infarction, need to combine medical history, symptoms, ECG and other examinations to make a diagnosis.
