STEMI negative : the EMS automated interpretation read, “STEMI negative. According to the STEMI paradigm, the patient doesn’t have an acute coronary occlusion and doesn't need emergent reperfusion, so the paramedics can bring them to the ED for assessment, without involving cardiologists. Inferior infarct, age undetermined.

Acute coronary syndrome (ACS) is responsible for the majority (60%) of all OHCAs in patients. There is evidence that taking those patients with ROSC and EKG showing STEMI directly for angiography +/- angioplasty is associated with positive patient-oriented outcomes.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. His response: “subendocardial ischemia. Anything more on history? POCUS will be helpful.”

Angiogram No obstructive epicardial coronary artery disease Cannot exclude non-ACS causes of troponin elevation including coronary vasospasm, stress cardiomyopathy, microvascular disease, etc. This has resulted in an under-representation of STEMI MINOCA patients in the literature. From Gue at al.

It should be emphasized here that this is a presentation of high-pretest probability for Acute Coronary Syndrome (ACS). There is mixed overlap of ST-segment elevation (STE), ST-segment depression (STD), Hyperacute T waves (HATW), and deWinter pattern (which the ACC regards as a STEMI-equivalent but is better suited under the blanket of OMI).

He had multiple cardiovascular risk factors and the EM physician strongly suspected ACS. Over the next few hours, four other general cardiologists "signed off on the initial ECG without recognizing STEMI." Learning Points: STEMI criteria misses 25-40% of OMI, like this case for example. mm of the "required" 1.0

BP 142/100 HR 90 RR 16 (BBS CTA) SpO2 99 (RA) Dstick 110 My colleagues noted the ST-depression in the respective leads, as well, and STEMI activated to the nearest PCI center. 1] Here is the admitting ED ECG after cancellation of Code STEMI. The EMS crews were correct moving forward with STEMI activation. 1] Driver, B.
