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).

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.

A recent study found that SCAD causes almost 20% of STEMI in young women. examined SCAD presenting as STEMI (unlike Hassan et al. Revascularization in Patients With Spontaneous Coronary Artery Dissection and ST-Segment Elevation Myocardial Infarction. A study by Hassan et al. Lobo et al. The SCAD cases in Lobo et al.

Occlusion myocardial infarction is a clinical diagnosis Written by Willy Frick (@Willyhfrick). Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." The case continues. Worrall, C.,

Limitations of registry data: This patient presented with STEMI (-) OMI and developed STEMI the following day. But the time that elapsed from first STEMI (+) ECG to balloon was 57 minutes, and THIS is what will be recorded for reporting to the National Cardiovascular Data Registry for purposes of quality improvement.

The authors describe a case with some features in common with our patient -- a stressful event followed by a stress cardiomyopathy/acute myocardial infarction overlap syndrome. Acute myocardial infarction: an uncommon complication of takotsubo cardiomyopathy. Acute myocardial infarction triggered by emotional stress.
