心肌损伤是脓毒症的重要并发症，也是导致脓毒症患者死亡的重要原因。脓毒症已被证明通过多个分子途径介导心肌损伤。随着16SrRNA和鸟枪测序等技术的应用以及相关病理生理机制理解的深入，研究者发现肠道菌群和脓毒症存在复杂的相互作用。不仅是脓毒症改变了肠道菌群分布，肠道菌群也广泛影响着脓毒症的发生和发展。一些基于肠道菌群的治疗方法也被认为有良好的应用前景。此外，肠道微生态已被大量研究证明与多种心血管疾病相关。然而，目前对脓毒症介导的心肌损伤中肠道菌群发挥作用的机制的了解仍然十分有限。该文综述了脓毒症、肠道菌群和心肌损伤相互影响的病理生理机制，有助于加深相关领域研究者的认识和思考。“,”Myocardial dysfunction is an essential complication of sepsis and a significant cause of death in patients with sepsis.Sepsis has been shown to mediate myocardial dysfunction through multiple molecular pathways.With the application of technologies such as 16SrRNA and shotgun sequencing and the in-depth understanding of related pathophysiological mechanisms, it has been discovered that there is a complex interaction between gut microbiota and sepsis.Not only does sepsis change the gut microbiota, but the gut microbiota also widely affects the occurrence and development of sepsis.Some treatment methods based on gut microbiota are also considered to have good application prospects.In addition, intestinal microecology has been proved by a large number of studies to be related to various cardiovascular diseases.However, the current understanding of the mechanism by which the gut microbiota plays a role in sepsis-mediated myocardial dysfunction is still minimal.This article summarizes the pathophysiological mechanisms of sepsis, gut microbiota, and myocardial dysfunction that affect each other, which is helpful to deepen the understanding and thinking of researchers in the related fields.
