Cardiac arrest can cause diffuse subendocardial ischemia, usually transient (it often resolves as time goes by after ROSC). It was stented. Also, anterior MI could result from 1) ACS, but also from 2) severe ischemia due to combination of a hemodynamically significant LAD stenosis + severe hypotension during cardiac arrest.

Given the presentation, the cardiologist stented the vessel and the patient returned to the ICU for ongoing critical care. Echocardiogram showed LVEF 66% with normal wall motion and normal diastolic function. Lesions less than 70% are generally considered to be non-flow limiting. Two subsequent troponins were down trending.

I think a good start would be a posterior EKG and a high quality contrast echocardiogram read by an expert. It was thought to be an in stent restenosis and thrombosis from a DES placed in the same region 6 months prior. His prior EF from an ECHO 6 months prior indicated 35% LVEF. What would you do in this scenario?

Smith comment: The patient was lucky to have a cardiac arrest. By undergoing an arrest, providers became aware of his OMI which had not been noticed on his diagnostic ECG, and he thus has a chance at some myocardial salvage. Total proximal LAD occlusion was found and stented at angiography soon after the ECG above.
