Objective: To approach the relation of myocardial remodeling and expression of growth factor derived from platelet (PDGF-B) after myocardial infarction.Methods:Myocardial remodeling models o f myocardial infarction in Wistar rats were used to study expression changes of collagen subtype Ⅰ
Ⅲ and PDGF-B with immunohistochemistry and image analysis .Results: Cardiac collagen Ⅰ
Ⅲ and PDGF-B were increased (P<0.01) in myocardial infarction groups compared with those in sham group.Collagen Ⅰ and collagen Ⅲ levels correlated positively to PDGF-B levels significantly (P<0.01).Conclusion: Myocardial remodeling after myocardial infarction may be induced ultimately by PDGF-B expression of modulating fibroblast with various pathogenesis.
