File:IPLab3HealedMyocardialInfarction8.jpg
This is a higher-power photomicrograph of a trichrome-stained section of heart containing an old healed MI. The scar tissue (mature fibrous connective tissue) is stained blue.
File:IPLab3HealedMyocardialInfarction7.jpg
This is a photomicrograph of a trichrome-stained section of heart containing an old healed myocardial infarction. The scar is composed of mature fibrous connective tissue (arrows).
File:IPLab3HealedMyocardialInfarction6.jpg
This is a photomicrograph of a trichrome-stained section from a heart with an acute myocardial infarction. Note that there is little fibrous connective tissue. It is too early for scar formation to have taken place in this acute lesion.

File:IPLab3HealedMyocardialInfarction5.jpg
This is a high-power photomicrograph of a different region of this healed MI. Note the chronic inflammatory reaction (arrows) in this region suggesting that there had been ischemic injury to this area within the last several weeks to months.
File:IPLab3HealedMyocardialInfarction4.jpg
This is another high-power photomicrograph of a healed myocardial infarction. Note the remaining normal myocytes (1), the fibrous connective tissue (2), and occasional hypereosinophilic myocytes indicating recent acute ischemic injury (arrow).
File:IPLab3HealedMyocardialInfarction3.jpg
This is a higher-power photomicrograph of a healed myocardial infarction with a fibrous scar. Remaining normal tissue is at the top (1) and the fibrous connective tissue scar is at the bottom (2). Note the presence of occasional hypereosinophilic myocy...
File:IPLab3HealedMyocardialInfarction2.jpg
This is a low-power photomicrograph of a healed myocardial infarction with a fibrous scar. Remaining normal tissue is on the left (1) and the fibrous connective tissue scar is on the right (2).
File:IPLab3HealedMyocardialInfarction1.jpg
This is a gross photograph of a heart with areas of old healed myocardial infarction (scars) outlined by arrows.

File:IPLab3AcuteMyocardialInfarction7.jpg
This is a photomicrograph of the lines of Zahn. Pale areas (1) represent platelets with some fibrin and the darker lines (2) represent RBCs and leukocytes enmeshed in fibrin strands.
File:IPLab3AcuteMyocardialInfarction6.jpg
This is a low-power photomicrograph of a mural thrombus (1) adherent to the endocardial surface (arrows).
File:IPLab3AcuteMyocardialInfarction5.jpg
This is a high-power photomicrograph of another area of this section. There are several hypereosinophilic cells within this section (arrows).
File:IPLab3AcuteMyocardialInfarction4.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.
File:IPLab3AcuteMyocardialInfarction3.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:IPLab3AcuteMyocardialInfarction2.jpg
This is a higher-power photomicrograph which shows more clearly the viable tissue along the epicardium (1), the blue line of inflammatory cells (2), and the infarcted myocardium (3).
File:IPLab3AcuteMyocardialInfarction1.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 thr...

File:IPLab3BrainInfarction11.jpg
This is a closer view of the brain demonstrating an old healed infarct with the meninges containing blood vessels (arrow) overlying the infarcted region.
File:IPLab3BrainInfarction10.jpg
This is a gross photograph of a brain from another patient with an old healed infarct. Note the meninges overlying the infarcted region (arrow).
