2024 Chest Pain STEMI

Written by Jesse McLaren A 45-year-old presented with 24 hours of intermittent chest pain. On it’s own this is nonspecific, but in the right context this could be diagonal occlusion (if active chest pain) or infero-posterior reperfusion (if resolved chest pain). #2 Can you guess the sequence?

Written by Jesse McLaren, with a very few edits by Smith A 60-year-old presented with chest pain. The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. But STEMI criteria is only 43% sensitive for OMI.[1]

Written by Jesse McLaren A healthy 75 year old developed 7/10 chest pain associated with diaphoresis and nausea, which began on exertion but persisted. Below is the first ECG recorded by paramedics after 2 hours of chest pain, interpreted by the machine as “possible inferior ischemia”. What do you think?

Written by Pendell Meyers A man in his 60s presented with acute chest pain and normal vital signs. Its hard to measure the STE in I exactly with the moving baseline, but there is almost certainly not enough STE to meet STEMI criteria. Here is his triage ECG: What do you think? They are symmetric, fat, convex on both sides, etc.

Written by Jesse McLaren A previously healthy 60 year old developed exertional chest pain with diaphoresis, and called EMS. So while there’s no diagnostic STEMI criteria, there are multiple ischemic abnormalities in 11/12 leads involving QRS, ST and T waves, which are diagnostic of a proximal LAD occlusion. What do you think?

Written by Jesse McLaren, comments by Smith A 55 year old with a history of NSTEMI presented with two hours of exertional chest pain, with normal vitals. See these posts: Chest Pain, ST Elevation, and an Elevated Troponin: Should we Activate the Cath Lab? So this NSTEMI was likely a STEMI(-)OMI with delayed reperfusion.

Written by Willy Frick A man in his 50s with history of hypertension, hyperlipidemia, and a 30 pack-year smoking history presented to the ER with 1 hour of acute onset, severe chest pain and diaphoresis. For national registry purposes, this will be incorrectly classified as a STEMI.) Most STEMI have peak cTnI greater than 10.0.
