The invention discloses application of collagen targeted vascular
endothelial growth factors in old
myocardial infarction treatment. In the application, the collagen targeted vascular
endothelial growth factors are fused proteins obtained by fusing collagen binding regions at the ends N and / or C of the vascular
endothelial growth factors, the vascular endothelial growth factors are proteins shownfrom the first site to the 166th site with the
amino acid sequence of SEQ ID No.1, and the collagen binding regions are proteins shown from the 178th site to the 184th site with the
amino acid sequence of SEQ ID No.1. It is shown through experiments that the collagen targeted vascular endothelial growth factors have the capacity of being combined with a
cell epimatrix and can be specifically combined with an
ischemia cardiomyocyte epimatrix, the myocardial
ischemic injury repairing effect is improved, the side effects of VEGF high-dosage
medicine application can be avoided, and the collagen targeted vascular endothelial growth factors can be used for treating the old
myocardial infarction.
