TGFB1 and myocardial infarction: In fact, the up‐regulation of the TGFB1 pathway is known to be related to cardiac fibrosis during MI and cardiac remodelling.46, 47, 48 Therefore, our results suggest that the inhibition of the TGFB1 pathway‐regulated network, which includes 74 genes, as shown in the present study, is an important molecular mechanism for the early moderate exercise‐mediated improvement of cardiac fibrosis and cardiac remodelling in MI.
