Patient 2 A man in his 50s with history of CAD and prior PCI, diabetes, presented with acute constant chest pain for the past few hours. Triage ECG: It was interpreted as lateral STEMI, and he was sent to the cath lab, where the angiogram showed unchanged CAD from known prior, with no acute culprit. He was discharged home.

This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. Sinus tachycardia has many potential causes.

He has a history of known CAD, diabetes, and dyslipidemia. The STD in V2-V4 is almost certainly reciprocal STD, reciprocal to STEMI in the posterior wall; this is evident because it is maximal in V2-V4, not in V4-V6. Moreover, T-wave inversion in aVL was also found to be 100% sensitive and 86% specific for inferior STEMI.

A middle-aged diabetic dialysis patient presented with 24 hours of nausea and vomiting associated with ~6 pound weight loss. It is uncommon in the age of reperfusion therapy, as most STEMI get treated reasonably early, before transmural infarct. Most STEMI peak at over 10 ng/mL; most NonSTEMI at less than 10 ng/mL.

A 50 something-year-old man with a history of newly diagnosed hypertension and diabetes, for which he did not take any medication, presented a non-PCI-capable center with a vague, but central chest pain. Such an out-of-proportion STE is virtually never seen in pericarditis. Written by Emre Aslanger. Emre is a new Editor of the Blog.

Written by Willy Frick A man in his mid 30s with type 1 diabetes presented with two days of midsternal and epigastric pain, described as both "sharp" and squeezing." The emergency medicine physician documented, "His initial EKG is riddled with artifact and difficult to interpret but does not look like a STEMI."

.: 50% of LAD STEMI have Q-waves by one hour. The exception is with postinfarction pericarditis , in which a completed transmural infarct results in inflammation of the subepicardial myocardium and STE in the distribution of the infarct, and which results in increased STE and large upright T-waves. So it is not necessarily subacute.
