Elevated troponin levels are the most specific and sensitive markers for myocardial injury, making them the most helpful in determining whether a patient has suffered cardiac injury. Troponin levels can remain elevated for an extended period after myocardial infarction, providing a wider diagnostic window compared to other markers.
