Majority of Wellens end up as NSTEMI, statistics tells us about 20% of them can be STEMI in incognito mode demanding lysis or emergency PCI. ECG will remain same. How to manage Wellen syndrome?

Smith : there is some minimal ST elevation in V2-V6, but does not meet STEMI criteria. Transient STEMI has been studied and many of these patients will re-occlude in the middle of the night. Is it normal STE? The computer thinks so, and the physician thinks that is quite possible. However , there is terminal QRS distortion in lead V3.

The precordial ST-depression pattern on this ECG (and in this clinical setting) should immediately raise suspicion of Posterior STEMI! Posterior STEMI occurs in approximately 15-20% of acute MI, but the vast majority of the time it is seen in conjunction with inferior (Infero-Posterior) or lateral (Postero-Lateral) STEMI (1).

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."

His ECG was repeated at this point: This shows a well developed anterior STEMI. To not see these findings is very common, and this patient would be given the diagnosis of NonSTEMI, with subsequent development of STEMI. It is not a missed STEMI, but it is a missed coronary occlusion. The peak troponin I was over 100.

I am going to code this as an acute STEMI as he had transient ST elevation which started to evolve in the emergency department but I think this is most appropriately termed STEMI." When is it anterior STEMI? No formal echo was done, and EF was normal on ventriculogram during cath, with no obvious wall motion abnormalities.
