Final answer:
The most sensitive indicator for myocardial damage is Troponin. Troponin is a protein found in cardiac muscle cells and is released into the bloodstream when there is damage to the heart muscle. Elevated levels of troponin can be detected through a blood test and are a reliable indicator of myocardial damage.
Step-by-step explanation:
The most sensitive indicator for myocardial damage is Troponin. Troponin is a protein found in cardiac muscle cells. When there is damage to the heart muscle, troponin is released into the bloodstream. Elevated levels of troponin can be detected through a blood test and are a reliable indicator of myocardial damage.
Creatine kinase (CK), myoglobin, and lactate dehydrogenase (LDH) are also cardiac isoenzymes that can be used to diagnose myocardial damage, but troponin is the most sensitive and specific marker for cardiac injury. Elevated levels of troponin can be detected through a blood test and are a reliable indicator of myocardial damage.
