2022 Ischemia Ultrasound

Bedside cardiac ultrasound with no obvious wall motion abnormalities. This confirms that the pain was ischemia and is now resovled. BP initially 160s/90s, O2 sats 95% on room air. The cardiology fellow agreed with plan for emergent cath and escorted the patient to the cath lab. Nor was there a challenge to look for coronary spasm.

He arrived in the ED and had an immediate bedside cardiac ultrasound while this ECG was being recorded. The bedside ultrasound (video not available) reportedly showed only a slightly reduced LV function. The patient was given 6mg, then 12 mg, of adenosine, without a change in the rhythm. Here is the ECG: What do you think?

The differential is: Posterolateral OMI or subendocardial ischemia The distinction between posterior OMI and subendocardial ischemia can be important and sometimes difficult. Bedside ultrasound is another very important piece. Ischemic ST depression includes posterior OMI and subendocardial ischemia.

A majority (62.5%) of those presenting with ‘normal’ ECGs had the cath lab activated without any ECG being labeled ‘STEMI’ by automated interpretation – based on signs of Occlusion MI including ECG changes, regional wall motion abnormality on bedside ultrasound, or refractory ischemia. 2022 ; 51 : 384 - 387 3.

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. Now another, with ultrasound. The rhythm is atrial fibrillation. What is the Diagnosis?

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?
