Myocardial infarctions can be classified temporally from clinical and other features, as well as according to the pathological appearance as:

• Evolving phase of myocardial infarction: (>6 hours),
• Acute phase of myocardial infarction: (6 hours – 7 days),
• Healing phase of myocardial infarction: (7–28 days),
• Healed phase of myocardial infarction: (29 days and beyond).

Time from Onset and Gross Morphologic Finding Relations

• 18 - 24 hours: Pallor of myocardium
• 24 - 72 hours: Pallor with some hyperemia
• 3 - 7 days: Hyperemic border with central yellowing
• 10 - 21 days: Maximally yellow and soft with vascular margins
• 7 weeks: White fibrosis

Gross Pathological Findings

Myocardial Infarction: Gross; Left ventricle; a mural thrombus.

Myocardial Infarction: Gross; An excellent example of all ventricular slices in case of healing posterior and healed anterior myocardial infarction. A mural thrombus at apex.

Myocardial Infarction: Gross; A ventricular slice near apex; Large old anterior and posterior transmural infarctions with mural thrombosis.

Myocardial Infarction: Gross; External view showing indented area represent small posterior wall aneurysm.

Myocardial Infarction: Gross; close-up view of anterior wall of left ventricle with dimpling due to aneurysm. Surrounding hyperemia indicates acute infarction.
