Since then, I started looking for OMI EKG findings and not just STEMI. Remember: these findings above are included as STEMI equivalent findings in the 2022 ACC Expert Consensus Decision Pathway on ACS Patients in the ED. mm in lead I, thus not STEMI criteria) and was finally understood by the cardiologist.

However, a smooth tapering of the mid-RCA was seen, highlighted in red below: How do we explain the MI if no sign of CAD was found? This MI wasn’t caused by a ruptured plaque of CAD - it was a coronary artery dissection of the RCA. SCAD isn’t rare, especially in women Historically SCAD had been identified in 22% of ACS cases in women.

Well, most commonly we’re going to see ACS. As the pregnant population continues to age and with RF and smoking and DM still common we can expect to see pregnant woman with CAD. What can we expect to see in terms of cardiac disease? Valve disease provides the most interesting part of obstetric care.

The fire department, who operate at an EMT level in this municipality, arrived before us and administered 324 mg of baby aspirin to the patient due to concern for ACS. Just because you don't see hemodynamically significant CAD on angiogram does not mean it is not OMI. I could have told you this (and did tell you this) without an MRI.

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. In our opinion it should not be given in ACS unless you are committed to the cath lab.

If this is ACS with Aslanger's pattern , the ST depression vector of subendocardial ischemia (due to simultaneous 3 vessel or left main ACS) is directed toward lead II (inferior and lateral). Thus, this apparently is Aslanger's Pattern (inferior OMI with single lead STE in lead III, with simultaneous subendocardial ischemia).

But if they do present: The very common presentation of diffuse STD with reciprocal STE in aVR is NOT left main occlusion , though it might be due to sub total LM ACS, but is much more often due to non-ACS conditions, especially demand ischemia. All are, however, clearly massive STEMI. This was a 100% acute LM occlusion.

This is technically a STEMI, with 1.5 However, I think many practitioners might not see this as a clear STEMI, and would instead call this "borderline." They collected several repeat ECGs at the outside hospital before transport: None of these three ECGs meet STEMI criteria. This ECG was recorded on arrival: What do you think?

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. This case represents the same physiologic event as OMI in terms of the result on the myocardium, therefore with identical ECG features, however there may not be ACS!

A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.

A middle-aged male with h/o CAD and stents presented with typical chest pressure. It may be difficult to read STEMI in the setting of RBBB. There is, however, a long QT also, with abnormal T-waves, but this is not STEMI. So there is pathologic ST elevation here, consistent with anterolateral STEMI. Called 911.

She had zero CAD risk factors. It is equivalent to a transient STEMI. Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. hours of substernal chest pressure.

Written by Pendell Meyers A man in his late 40s with several ACS risk factors presented with a chief complaint of chest pain. The cardiologists felt that the ECG did not represent ACS, and thought it was more likely pericarditis, so they did not take him to the cath lab. His first troponin T then resulted elevated at 0.19 Pericarditis?
