Here is the post shock ECG: Cardiology was called stat for ischemic VT, query SCAD vs thrombotic occlusion vs coronary vasospasm. Cath lab was activated: There was no coronary artery disease, but there was spontaneous coronary artery dissection (SCAD) of the distal LAD, which was narrowed by 95%, and treated medically.

This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI.

In the absence of these factors it is termed spontaneous coronary artery dissection ( SCAD ). At that time the literature suggested: SCAD was rare , Mostly related to pregnancy , Seen on angiography as a dissection flap , and Managed similarly to MI caused by CAD (ASA, BB, lytics/PCI ). The SCAD cases in Lobo et al. Lobo et al.

There is clearly sufficient STE for STEMI criteria in leads V2 and aVL, but lead I has less than 1.0 mm of STE - thus, technically this ECG does not meet STEMI criteria, although it is a quite obvious OMI. This ECG was immediatel y discussed with the on-call cardiologist who said the ECG was "concerning but not a STEMI."

It is equivalent to a transient STEMI. Not much, but studies of STEMI and NonSTEMI show that about 70% of those diagnosed with STEMI have a peak troponin I above 10 ng/mL and that about 70% of those diagnosed with NonSTEMI have a peak troponin I below 10 ng/mL. What is Spontaneous Coronary Artery Dissection (SCAD)?

This is a troponin I level that is almost exclusively seen in STEMI. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest had another etiology (such as old scar), and the ST elevation is due to severe shock, then it is a type II STEMI. I believe the latter (type II STEMI) is most likely.

She had this ECG recorded: Obvious massive anterior STEMI She was quickly brought to the critical care area and the cath lab was activated. Here is the ECG at 25 minutes: Terrible LAD STEMI (+) OMI So a CT scan was done which of course showed a normal aorta. This time the Queen of Hearts interpreted: No STEMI or Equivalent.
