Acute myocaridial Infarct
Acute myocaridial Infarct

Note the copious exudate of PMN's between the muscle fibers.
Note the absence of nuclei in the myocardial fibers indicating necrosis, i.e., infarction.
PMN's have a life span of 24 hours, and then undergo karyorrhexis, which is not seen here, suggesting that this lesion is less than 2 days old.
