Right precordial ST depression in a patient with chest pain

Dr. Smith's ECG Blog

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).

A Tough ECG, But Learn From It!

Dr. Smith's ECG Blog

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 young peripartum woman with Chest Pain

Dr. Smith's ECG Blog

A recent study found that SCAD causes almost 20% of STEMI in young women. examined SCAD presenting as STEMI (unlike Hassan et al. I had no idea SCAD was so common a cause of acute STEMI in younger women, even when they are non-smokers. A study by Hassan et al. Lobo et al. where more than 3/4 of cases were NSTEMI).

Occlusion myocardial infarction is a clinical diagnosis

Dr. Smith's ECG Blog

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." Immediate versus delayed invasive intervention for non-stemi patients. JACC: Cardiovascular Interventions , 9 (6), 541–549.
