脓毒性心肌病的发生率和病死率均较高,是脓毒症患者常见的死亡原因之一.脓毒性心肌病的发病机制尚不十分清楚,心肌细胞线粒体功能障碍在其病理过程中起着十分重要的作用.本文从心肌细胞线粒体能量代谢的调节、线粒体损伤机制、水通道蛋白的作用及线粒体动力学的调控等方面,综述脓毒性心肌病的线粒体机制,以期对早期预防其发生提供帮助.

The incidence and mortality of septic cardiomyopathy were high, which is the common cause of death in the patients with sepsis. The pathogenesis of sepsis induced myocardial injury is still unclear. The mitochondrial dysfunction of myocardial cells plays a very important role in the pathophysiological mechanism. This review attempts to introduce the mitochondrial damage of cardiomyocyte from the regulation of mitochondrial energy metabolism, the mechanism of mitochondrial damage, the role of aquaporin and the adjustment of mitochondrial dynamic, in order to provide help for the early prevention of septic cardiomyopathy.
