It should be emphasized here that this is a presentation of high-pretest probability for Acute Coronary Syndrome (ACS). ACE inhibitors, or potassium-sparing diuretics), are particularly susceptible. In the case of ACS, the ECG can rapidly change from this. Past medical history included HTN, HLD, and MI 10 years prior.

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. Fortunately, that is exactly what happened.
