EGR2 and myocardial infarction: Instead, compared with the mice injected with the Ad-sh-MIAT, LVEDD and LVESD values of the mice injected with Ad-sh-MIAT + oe-EGR2 increased significantly, and EF and FS values decreased significantly (p < 0.05, Figure 5A), indicating that overexpression of EGR2 aggravated the cardiac dysfunction of mice after MI.
