Figure B At this point, with the ECG changing from diffuse ST depression to widespread ST elevation and the patient presenting in cardiogenic shock, left main coronary artery (LMCA) occlusion is the likely diagnosis. The arrhythmia spontaneously converted before defibrillation was achieved. This is an ominous sign. As per Dr.

Angiography : LMCA — 90-99% osteal stenosis. LCx — 50-69% stenosis of the 1st marginal branch; with 100% distal LCx occlusion. The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. RCA — 100% proximal occlussion. What do you think?

Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). In addition, the top left blue arrow indicates a section in the LAD with a severe stenosis, likely the culprit for the prior L A D occlusion which has since recanalized. There are also diagonal branches which are not well visualized.
