1 Serum levels increase within 3-12 hours from the onset of chest pain, peak at 24-48 hours, and return to baseline over 5-14 days. 2  Troponin levels may not be detectable for six hours after the onset of myocardial cell injury. 3  The most sensitive early marker for myocardial infarction is myoglobin.
Certain subtypes of troponin (cardiac I and T) are very sensitive and specific indicators of damage to the heart muscle (myocardium). They are measured in the blood to differentiate between unstable angina and myocardial infarction (heart attack) in people with chest pain or acute coronary syndrome.A person who recently had a myocardial infarction would have an area of damaged heart muscle and elevated cardiac troponin levels in the blood.roponin is a complex of three regulatory proteins (troponin C, troponin I, and troponin T) that is integral to muscle contraction in skeletal muscle and cardiac muscle, but not smooth muscle.
