Gross Pathology
Myocardial infarction can be classified temporally from clinical and other features, as well as according to the pathological appearance as:[1]
- 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
