I would like to get some clarification on the timeline of events that occur after an MI.
I just got a UWorld question (Q. id 41 for those interested) that I got wrong because of conflicting information in first aid.
The question basically presents a man found dead in his apartment post-MI day 12. It then asks what microscopic features would you see on tissue biopsy.
First aid generalizes that between 3-14 days you are going to be macrophage clearing of cellular debris and granulation tissue formation beginning along the perimeter of the infarct. Given that this guy dropped dead, I assumed he had a wall rupture, which is caused from macrophage induced weakening of the ventricular wall. The answer was instead that you should observe granulation tissue with re-vascularization.
UWorld doesn't even address why this man died, just gives a timeline for events that is completely different from First Aids and other resources that I have.
