WebThis new test, which is not yet widely available, is called a high-sensitivity troponin test. Troponin is a protein released by damaged heart cells during a heart attack. The new test detects much lower levels of troponin, and therefore smaller amounts of damage, than the one currently used as standard. WebThese cardiac biomarkers can be used to diagnose a heart attack: Cardiac troponin. This protein is by far the most commonly used biomarker. It has the highest known sensitivity. It enters into your bloodstream soon after a heart attack. It also stays in your bloodstream days after all other biomarkers go back to normal levels.
