VEGFA and myocardial infarction: Zhen et al.(Zhen et al., 2016) established a rat model of MI and found that the treatment of Huoxue Yiqi decoction (1 g/g−1/d−1) in rats by gavage decreased the expression of miR-126, inhibited the regulation of VEGF by miR-126, and increased the expression of VEGF, thereby promoting angiogenesis.
