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. After all, there is no S wave in lead V3.

Opioids do not cause ACS but they can exacerbate hypoxia in patients with ACS. Older children and adults usually present with ACS 2-3 days after hospitalisation due to pulmonary infarction (in situ sickling), hypoventilation due to rib infarction (which may be exacerbated by recent narcotic administration) or fat embolism.

Some providers were worried about ACS because of this ECG. My answer alleviated their concern for ACS and no further workup was done for ACS. Kosuge et al. showed that , when T-waves are inverted in precordial leads, if they are also inverted in lead III and V1, then pulmonary embolism is far more likely than ACS.

This pattern in isolation would signify diffuse supply/demand mismatch without focal complete occlusion, which would be a very large differential of anything causing severe global supply demand mismatch, including ACS and various other processes.
