Acute Inhibition of Excessive Mitochondrial Fission After Myocardial Infarction Prevents Long‐term Cardiac Dysfunction

Together, we show that excessive mitochondrial fission at reperfusion contributes to long-term cardiac dysfunction in rats and that acute inhibition of excessive mitochondrial fission at the onset of reperfusion is sufficient to result in long-term benefits as evidenced by inhibiting cardiac dysfunction 3 weeks after acute myocardial infarction.
