I advised that perhaps posterior leads would help to persuade the interventionalist, since the 2022 ACC recommendations include posterior STEMI as a formal STEMI equivalent, but only officially by 0.5 Angiogram reportedly showed acute thrombotic occlusion of the first obtuse marginal which was stented. mm STE in the posterior leads.

A man in his 70s with past medical history of hypertension, dyslipidemia, CAD s/p left circumflex stent 2 years prior presented to the ED with worsening intermittent exertional chest pain relieved by rest. The baseline ECG is basically normal with no ischemia. In my opinion, I think it looks more like subendocardial ischemia.

In any case, the ECG is diagnostic of severe ischemia and probably OMI. So this could be myocarditis but in my opinion needs an angiogram before making that diagnosis. == Dr. Nossen Comment/Interpretation: Evaluation of ischemia on an ECG can be very challenging. Concordant STE of 1 mm in just one lead or 2a.

Written by Jesse McLaren A 70 year old with prior MIs and stents to LAD and RCA presented to the emergency department with 2 weeks of increasing exertional chest pain radiating to the left arm, associated with nausea. Clin Cardiol 2022 4. But no ECG met STEMI criteria so the patient was referred to cardiology as Non-STEMI. Lupu et al.

The patient is female in her 80s with a medical hx of previous MI with PCI and stent placement. Are you confident there is no ischemia? Primary VT , and the VT with tachycardia is causing ischemia with chest discomfort (supply-demand mismatch/type 2 MI)? The last echocardiography 12 months ago showed HFmrEF.

The cath lab was activated, and then not cancelled, and the angiogram showed 99% TIMI 2 flow proximal LAD culprit lesion, stented in less than 90 minutes of arrival. Cath days later showed complete occlusion of the LAD, stented. Ultimately, cardiac cath was done in Case #2, with stenting of the "culprit" LAD lesion.

The fact that R waves 2 through 6 are junctional does make ischemia more difficult to interpret -- but not impossible. Back to the assessment of ischemia: Returning to the ECG, the leads that catch my eye first are -- I, II, V4, V5, V6. Ischemia can be disguised by a wide escape rhythm, which decreases the sensitivity of ECG.
