A patient had a cardiac arrest with ventricular fibrillation and was successfully defibrillated. This is FAR LESS than all other studies of shockable arrest. Coronary Angiography after Cardiac Arrest without ST-Segment Elevation. The proof of this is that only 5% of patients enrolled had acute coronary occlusion.

Shortly after arrival in the ED ( E mergency D epartment ) — she suffered a cardiac arrest. BUT — Cardiac catheterization done a little later did not reveal any significant stenosis. Figure-1: The initial ECG in today's case — obtained after successful resuscitation from cardiac arrest. (

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. aVR ST segment elevation: acute STEMI or not? His response: “subendocardial ischemia.

An echocardiogram confirmed aortic stenosis with a large pressure gradient. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. The next day, and angiogram showed normal coronary arteries. He awoke and did well.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. Angiography : LMCA — 90-99% osteal stenosis. LCx — 50-69% stenosis of the 1st marginal branch; with 100% distal LCx occlusion. The patient in today’s case is a previously healthy 40-something male who contacted EMS due to acute onset crushing chest pain.

This is a troponin I level that is almost exclusively seen in STEMI. I suspect this is Type 2 MI due to prolonged severe hypotension from cardiac arrest. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA.

Could this be Septal STEMI (STE in V1 and aVR, with reciprocal ST depression in V4-V6?), In Septal STEMI , transmural ischemia of the septum is recorded by the overlying lead V1 as ST Elevation. Lead III is also on the right and might manifest ST Elevation in Septal STEMI. with ADDED STE in III?
