Final answer:
Elevated Troponin levels indicate a myocardial infarction (MI) or heart attack. It is a sign of damage to the heart. Other blood tests, such as elevated creatine kinase MB levels, can also confirm an MI.
Step-by-step explanation:
Elevated Troponin levels are diagnosed as an indication of a myocardial infarction (MI) or heart attack. Troponin is a regulatory protein for muscle contraction, and when damaged cardiac muscle cells release it into the blood, it indicates damage to the heart. Other blood tests that can confirm an MI include elevated levels of creatine kinase MB, which is an enzyme released by damaged cardiac muscle cells.
