[Expression of myocardial collagen I in early acute myocardial ischemic of human].

Objective: To estimate the significance of myocardial collagen I in the early acute myocardial ischemia of human.

Methods: The myocardial paraffin block had normal group, early myocardial ischemia group and myocardial infarction group. The myocardial collagen I was observed with immunohistochemical staining and analyzed by half-quantity.

Results: The similar expression of collagen I was observed in the cytoplasm and nucleolus in two groups.

Conclusion: The collagen I appeared in the myocardium of early acute myocardial ischemia of human. It may be an important index for postmortem diagnosis of the early acute myocardial ischemia.
