Immunohistochemical observation of heart-type fatty acid binding-protein in early myocardial ischemia / 法医学杂志

ABSTRACT

OBJECTIVE@#The sensitivity of heart-type fatty acid binding-protein (H-FABP) in the postmortem diagnosis of myocardial ischemia was explored.@*METHODS@#The changes of H-FABP staining in normal, infarcted and suspected ischemia of myocardial cells were studied by immunohistochemistry.@*RESULTS@#There was no depletion in normal control group, and obvious depletion was observed in myocardial infarcted group. Among 9 suspected myocardial ischemia group, 3 cases showed obvious depletion and 3 cases showed vague depletion for H-FABP, there were obvious depletion of Mb in 4 suspected myocardial ischemia cases and vague depletion in 2 cases for Mb. It is indicated that H-FABP can be used to diagnose early myocardial ischemia.@*CONCLUSION@#H-FABP is quite sensitive and useful for the diagnosis of early myocardial ischemia.
