Thus, these troponins are very concerning for ACS, and subsequent ones will probably be diagnostic of acute MI. Heitner et al. For this test it is VERY low (very good) at 4% at the 99th percentile -- 26 ng/L, but it will not be so good at a level of 9 ng/L. The troponin is trapped in the myocardium that is not being perfused.

Because there was proven thrombus (ACS) but the troponin never went above the 99% reference range (and therefore cannot be called MI -- definition of MI requires rise and/or fall of troponin with at least one value above the 99% reference range), this is UNSTABLE ANGINA with ST Elevation. This is not the case.

He had no symptoms of ACS. His HEAR score (before troponin resulted) was documented at 3, with documentation stating "low suspicion for ACS." A troponin this high in a patient with no known chronic troponin elevation, and active acute ACS symptoms, has a very high likelihood of type 1 ACS regardless of the ECG.
