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.

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.

But because the patient had no chest pain or shortness of breath, it was not deemed to be from ACS. They were less likely to have STEMI on ECG, and more likely to be initially diagnosed as non-ACS. Dialysis patients have a high rate of ACS without chest pain and high rate of delayed diagnosis and delayed reperfusion 2.

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.

There were zero patients in this study with a "normal" ECG who had any kind of ACS! Deutch et al. This defies all previous data on acute MI which would show that even undetectable troponins do not have a 100% negative predictive value. So this study is actually worthless. West J Emerg Med 2024).
