Interpretation: The ST elevation in I, aVL and V4-6 are indicative of a lateral wall MI. The ST depression in leads V1-2 is a manifestation of a posterior wall extension of the MI. The borderline ST changes in the inferior leads are reciprocation changes. I am not aware of the angiographic findings, but would suspect an occlusion of the left circumflex artery.
