It is unclear to me whether this case could represent 1) simple supply/demand mismatch due to increased demand from epinephrine, 2) Kounis syndrome (usually described as mast cell mediated coronary vasospasm during allergic reaction), 3) brief autolysed left main or LAD ACS with no findings on later echo and CT coronary angio, or 4) something else.

We who know ischemic ECGs know that really when T-wave inversion is specific for coronary thrombosis that it indicates reperfusion of the artery, not active occlusion. Learning Point: 1. For examples of such exceptions — See My Comment in the January 9, 2019 — August 22, 2020 — and June 30, 2023 posts in Dr. Smith's ECG Blog ).

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. The patient proceeded to cath where all coronaries were described as normal with no evidence of any CAD, spasm, or any other abnormality. So maybe she is better than I am.

1 The shortage in supply posed difficulties for hospitals that significantly depend on GE Healthcare as their supplier, which encompassed approximately 50% of hospitals in the United States (US). Production levels increased steadily back to baseline, achieving normal supply levels in February 2023. 11 Table 1.

Two recent interventions have proven in randomized trials to improve neurologic survival in cardiac arrest: 1) the combination of the ResQPod and the ResQPump (suction device for compression-decompression CPR -- Lancet 2011 ) and 2) Dual Sequential defibrillation. The patient had a volatile clinical course but awoke neuro intact.

Learning Points: 1. If the situation is not right for acute coronary occlusion, then the ECG findings probably do not represent acute coronary occlusion. Severely ill patients from any etiology can have very abnormal ECGs = My Comment by K EN G RAUER, MD ( 5/26 /2023 ): = There are more questions than answers in today's case.

1 The ED is a fast-paced environment where patient stability and life-and-limb-threatening conditions are prioritized. The pain began abruptly 1 hour ago, described as a stabbing sensation, and has occurred daily at the same time for the past week, each episode lasting about 45 minutes. Pain can be improved or exacerbated with meals.
