Initial phase of myocardial infarction leads to subendocardial necrosis involving < 50% of the myocardial thickness (subendocardial infarction); EKG shows ST-segment depression.
Continued or severe ischemia (>20 minutes) leads to transmural necrosis involving most of the myocardial wall (transmural infarction); EKG shows ST-segment elevation.
