The ST segment changes are compatible with severe subendocardial ischemia which can be caused by type I MI from ACS or potentially from type II MI (non-obstructive coronary artery disease with supply/demand mismatch). The arterial blood gas showed a lactic acidosis with a lactate level of 17mmol/L. As per Dr.
