47 yr old male dies 2 hrs after the onset of severe chest pain, diaphoresis and palpitations. At autopsy, LAD shows 100% occlusion. Light microscopy of the affected area of this pt's myocardium wud most likely demonstrate:

a.Edema and punctate hemorrhages
b.Myocyte hypereosinophilia
c.Dense interstitial neutrophil infiltrate
d.Extensive macrophage phagocytosis of the dead cells
e.Fibrovascular granulation tissue with neovascularization
f.Dense collagen scar
g.Normal myocardium

sorry aa??

bergkamp,
most of the time, one shud go with their first instinct.

g is correct.


0-4hrs============minimal change
4-12hrs===========early coagulative necrosis, edema, hemorrhages, wavy fibers
12-24hrs==========coagulative necrosis and marginal contraction band necrosis
1-5 days==========coagulative necrosis and neutrophilic infiltrate
5-10 days=========macrophage phagocytosis of dead cells
10-14 days====granulation tissue and neovascularization
2wks-2mths====collagen deposition and scar formation
