MTOR and myocardial infarction: Consistent with our previous results on the cardiomyocyte injury model induced by hypoxia/reoxygenation, the myocardial protective mechanism of HSYA in the rat MI/R model may involve the promotion of myocardial autophagy by regulating AMPK/mTOR signaling pathway, inhibition of the activation of NLRP3 inflammasome, and reduction of the expression of downstream inflammatory factors to protect the ischemic myocardium.
