This is documented as a STEMI in the clinical notes and in the cath report, but certainly does not meet STEMI criteria and is therefore an NSTEMI by definition. For national registry purposes, this will be incorrectly classified as a STEMI.) Most STEMI have peak cTnI greater than 10.0. Large STEMI are approximately 30-80.

Intra-procedural data included access route, coronary anatomy, lesion complexity, number of stents deployed, door-to-balloon time for primary PCI, and any intra-procedural complications. Pre-procedural data included patients’ baseline characteristics (age, gender, clinical presentation and comorbidities).

Looking at the location of ST elevation ( ie, in the inferior leads — and in V4,5,6 ) — and the location of ST depression ( ie, in leads I,aVL; V1,V2 ) — this ECG picture suggests an ongoing acute infero - postero - lateral STEMI.

There’s mild inferior ST elevation in III that doesn’t meet STEMI criteria, but it’s associated with ST depression in aVL and V2 that makes it diagnostic of infero-posterior Occlusion MI (from either RCA or circumflex)– accompanied by inferior Q waves of unknown age. Are there any signs of occlusion or reperfusion?

The first EKG was concerning for a Wellen’s-like pattern of subtle reperfusion changes in the setting of stuttering anginal-equivalent symptoms, but none were diagnostic of STEMI or OMI. Later in the night, the patient became bradycardic and developed a Mobitz II pattern , but he remained asymptomatic and hemodynamically stable.
