File:IPLab3AcuteMyocardialInfarction1a.JPG|This is a low-power photomicrograph of infarcted heart. There is a layer of surviving myocardial tissue (1) along the epicardium and then a blue line (2) which represents the accumulation of inflammatory cells at the border of the infarct. There is thrombotic material (3) adherent to the endocardial surface.

File:IPLab3AcuteMyocardialInfarction3b.JPG|This is a photomicrograph of the edge of the infarct with normal tissue on the left (1). The accumulation of inflammatory cells (2) is at the edge of the infarcted tissue (3).
File:IPLab3AcuteMyocardialInfarction4b.JPG|This is a higher-power photomicrograph of the edge of the infarct. The accumulation of inflammatory cells is on the left (1) and the infarcted tissue is on the right (2). Note that intact cells can be seen in the infarct but there are no nuclei.
