脓毒症心肌线粒体改变与干预的研究进展

Research progress in the changes and management of myocardial mitochondria during sepsis

约50%的脓毒症患者合并心脏收缩功能降低和心输出量减少,约11.4%患者甚至出现心功能衰竭。目前认为,脓毒症时心肌线粒体形态和功能的改变是心肌收缩功能降低的重要原因。长期以来人们对脓毒症时的心肌线粒体改变与干预的基础和临床研究开展了大量的实验。本文就近年来国内外有关脓毒症时心肌线粒体结构、功能、自噬作用、凋亡作用的改变与干预方面的研究进展做了总结论述。

Reduction of cardiac output and systolic function occurs in almost 50% septic patients.Meanwhile,11. 4% of them develop heart failure. Recently,it is believed that structural and functional changes of myocardial mitochondria are the main causes of cardiac systolic function’s reduction during sepsis.There have been a lot of the basic and clinical studies on septic changes and management of myocardial mitochondria for a long time. This review tries to summarize the domestic and foreign research progresses in the changes and management concerning the structure and function of myocardial mitochondria,mitophagy as well as apoptosis during sepsis.
