Theres ST elevation in V3-4 which meets STEMI criteria, which could be present in either early repolarization, pericarditis or injury. Lets see what happens in the current STEMI paradigm. Emergency physician: STEMI neg but with elevated troponin = Non-STEMI The first ECG was signed off. What do you think?

Echo on the day after admission showed EF of 30-35% and antero-apical wall akinesis with an LV thrombus [these frequently form in complete or near complete (no early reperfusion) anterior STEMI because of akinesis/stasis] 2 more days later, this was recorded: ST elevation is still present. An open 90% LAD was stented.

Submitted and written by Alex Bracey with edits by Pendell Meyers and Steve Smith Case A 50ish year old man with a history of CAD w/ prior LAD MI s/p LAD stenting presented to the ED with chest pain similar to his prior MI, but worse. Despite ongoing chest discomfort and an uptrending troponin, he never meets STEMI criteria.

Fire/EMS crews found him clammy and uncomfortable. No appreciable skin pallor. Is this OMI?

David Didlake Firefighter / Paramedic Acute Care Nurse Practitioner @DidlakeDW Peer review provided by Dr. Steve Smith @SmithECGblog I was conducting QA/QI on two very recent cases and was struck by the uniqueness of both. A prehospital STEMI activation was transmitted to the closest PCI center, and 324mg ASA was administered.

David Didlake Firefighter / Paramedic Acute Care Nurse Practitioner @DidlakeDW Peer review and commentary by Dr. Steve Smith [link] @SmithECGblog It is early-summer, approximately 1330 hours, no cloud cover overhead, and 86 degrees with high humidity. As it currently stands, an ST/S ratio >15% should raise awareness for new anterior STEMI.
