2. Anaemic infarct of the heart

Organ: Heart (slice)

Description:

We can see two different slices of the heart in different levels. The bottom is the best for this diagnosis. On the left side, on the lateral wall we can see some pathology. There’s some black discoloration with a white layer around it. Around the white layer you can (kinda-sorta, in theory) see a reddish zone around the white. (The greenish area with something black inside is just an artefact from when they attached the heart to the glass with string.)

Diagnosis: (Transmural(?)) myocardial infarct

Causes:

• Stenosis (narrowing) of the coronary artery because of atherosclerosis (90% of cases)
• Artherosclerotic stenosis + a thrombus
• Coronary spasm (contraction of the artery)
• Embolism (rare)
• Vasculitis (rare)

Theory:
