The invention relates to application of an OGN overexpression vector in preparation of a
medicine for preventing reperfusion arrhythmia, and belongs to the technical field of medicines. In order to solve the problem that an existing anti-arrhythmia
drug cannot effectively prevent reperfusion arrhythmia, the invention provides application of an OGN overexpression vector in preparation of a
drug for preventing reperfusion arrhythmia, and the OGN overexpression vector is a recombinant adeno-associated
virus vector and contains a
nucleotide sequence for coding OGN. According to the invention, the recombinant adeno-associated
virus vector carrying the OGN
gene is constructed to drive the efficient expression of the OGN
gene in myocardial cells, and the Nav1.5
protein expression level is up-regulated and the
sodium current
peak value is increased, so that the normal
rhythm of cardiac electrophysiological activity is maintained, and the targeted improvement of the
sodium ion channel function of the myocardial cells and the stability of cardiac
electrical conduction are realized. The time window design of the preventive
drug is highly matched with the
clinical diagnosis and treatment process, and the preventive drug has extremely high
operability and clinical transformation potential.
