Cardiac arrest can cause diffuse subendocardial ischemia, usually transient (it often resolves as time goes by after ROSC). An echocardiogram on day 3 showed no wall motion abnormality (but of course, these can resolved with reperfusion, and the more time it has to resolve from "stunning", the more likely it is to be resolved).

See this case: what do you think the echocardiogram shows in this case? ST elevation (STE) in lead augmented vector right (aVR), coexistent with multilead ST depression, was endorsed as a sign of acute occlusion of the left main or proximal left anterior descending coronary artery in the 2013 STEMI guidelines.

Formal echocardiogram showed normal EF, no wall motion abnormalities, no pericardial effusion. This definition was changed following an expert consensus panel in 2013 — so that all that is currently needed to diagnose Brugada Syndrome is a spontaneous or induced Brugada-1 ECG pattern, without need for additional criteria.

A formal echocardiogram was completed the next day and again showed a normal ejection fraction without any focal wall motion abnormalities to suggest CAD. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.
