A 60 yo with 2 previous inferior (RCA) STEMIs, stented, called 911 for one hour of chest pain. Here is his most recent previous ECG: This was recorded after intervention for inferior STEMI (with massive ST Elevation, see below), and shows inferior Q-waves with T-wave inversion typical of completed inferior OMI.

A male in his 40's who had been discharged 6 hours prior after stenting of an inferoposterior STEMI had sudden severe SOB at home 2 hours prior to calling 911. Is this acute STEMI? Is this an acute STEMI? -- Unlikely! He had no chest pain. Medications were aspirin, clopidogrel, metoprolol, and simvastatin.

The patient presented to an outside hospital An 80yo female per triage “patient presents with chest pain, also hurts to breathe” PMH: CAD, s/p stent placement, CHF, atrial fibrillation, pacemaker (placed 1 month earlier), LBBB. Most large STEMI have peak troponin I in the 20.0 This was stented with a 2.25 Next trop in AM.

Old ‘NSTEMI’ A history of coronary artery disease and a stent to the same territory further increases pre-test likelihood of acute coronary occlusion, including in-stent thrombosis. The patient had a history of ‘NSTEMI’ a decade prior, with an RCA stent. So this NSTEMI was likely a STEMI(-)OMI with delayed reperfusion.

A man in his mid 60s with history of CAD and stents experienced sudden onset epigastric abdominal pain radiating up into his chest at home, waking him from sleep. She knows the baseline is normal, and she knows the STEMI(-) OMI one is diagnostic of OMI, with the highest possible confidence. It is stented with good angiographic result.

The interventional cardiologist then canceled the activation and returned the patient to the ED without doing an angiogram ("Not a STEMI"). I advised that perhaps posterior leads would help to persuade the interventionalist, since the 2022 ACC recommendations include posterior STEMI as a formal STEMI equivalent, but only officially by 0.5

The purpose of this report is to use propensity score matching to determine gender-specific differences in clinical outcomes after percutaneous coronary interventions with polymer-free sirolimus-coated stents. In the unmatched STEMI subgroup, all-cause mortality was significantly higher in females driven by older age (P < 0.001).
