WebMar 15, 2024 · Troponin is a protein released into your blood after you experience a heart attack. High troponin levels can be indicators of other heart conditions or illnesses, too. Certain subtypes of troponin (cardiac I and T) are 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. This can also occur in people with coronary …
