2025 STEMI Stent

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?

The emergency medicine physician documented, "His initial EKG is riddled with artifact and difficult to interpret but does not look like a STEMI." The ECG remains positive for STEMI by GE. The true AV groove LCx was "jailed" by the stent and appears occluded in the post PCI image. The emergency physician consulted cardiology.

Case submitted by Andrew Grimes, Advanced Care paramedic, with additions from Jesse McLaren and Smith An 84-year-old male with a notable cardiac history (CABG, multiple stents) woke at 0500hrs with pressure in his chest, diaphoresis, and light-headedness. STEMI criteria are only 43% sensitive for OMI.

He reports this was similar to how he felt when he had his heart attack 4 years prior, now s/p 4 stents. Note: the 2022 ACC Expert consensus Chest pain guidelines state that "posterior STEMI-Equivalent" is a sign of acute coronary occlusion. 2/3 of STEMI have a peak 4th generation troponin I greater than 10.0 NSTEMI-OMI").

He had undergone stenting of the LAD several weeks ago (unclear whether elective for stable symptoms, or in response to acute coronary syndrome). Acute chest pain, right bundle branch block, no STEMI criteria, and negative initial troponin. Written by Pendell Meyers An adult man presented with acute chest pain.

He has a history of coronary artery disease and a STEMI two years prior that was treated with primary PCI. At the time of this initial ED ECG, his symptoms were improving ECG #1 on admission to the ED The patient was not seen quickly in the ED as it was a busy shift and the ECG did not meet STEMI criteria. The below ECG was recorded.

This ECG pattern is my favorite example of how the STEMI criteria are fundamentally flawed. At cath there was a 100% proximal LAD occlusion, which was opened and stented. We have a series of 20 TIMI-0 LAD Occlusions that do meet STEMI criteria. There is a de Winter T- wave pattern also in lead I. Troponin T peaked at 9378 ng/L.
