What is cardiac-specific troponin t?

A biomarker. Measurement of troponin t is used to help make the diagnosis of myocardial infarction (heart attack). The chemical leaks from damaged heart muscle and confirms injury to the heart. A new assay called highly sensitive troponin is now available and is 10 times more sensitive and increases the speed and accuracy of the diagnosis. If the result is negative 3 hours after chest pain, mi is unlikely.

When the heart is injured, some troponin leaks into the blood where it becomes measurable. Read more...
