Meanwhile, qPCR results showed an increase in inflammatory cytokines TNF‐α and IL‐6, indicating that the myocardial infarction can significantly enhance immune maturation of DCs, augment antigen presentation, and participate in inflammatory response of post‐infarction ventricular remodelling, which further hinders the recovery of cardiac function after MI. This evidence concerns the gene IL6 and myocardial infarction.
