Elevated serum troponin can be seen in myocardial infarction, left heart failure, etc. Only myocardial infarction that meets the indications for surgery requires stenting. Elevated serum troponin suggests myocardial injury, which includes myocardial infarction, unstable angina pectoris, external blunt myocardial injury, myocardial contusion, left heart failure caused by drugs or severe sepsis and other conditions, and “stenting” is also known as an interventional therapy, which is mainly used for myocardial infarction, so it’s not that troponin is elevated. Therefore, stenting is not always necessary in cases of increased troponin. In addition, not all myocardial infarctions can be treated with interventional stenting. The procedure is suitable for myocardial infarction within 12 hours of the onset of symptoms. Intervention is prohibited in the presence of severe congestive heart failure or arrhythmia, severe systemic infection, allergy to contrast media, and severe liver or renal insufficiency. The need for intervention should be determined by the clinician; the presence of elevated troponin suggests prompt hospitalization.
