Pathogenesis of sepsis-induced myocardial dysfunction

Abstract

Sepsis is a common disease in intensive care units (ICU), and the resulted multi-organ dysfunction syndrome (MODS) is the main cause of death in patients with severe sepsis. The cardiovascular system is one of the most important target organ for sepsis. The severity of cardiac dysfunction is closely related to the clinical prognosis of patients with sepsis. Studies have reported that various cytokines are expressed during sepsis. They have influence on myocardial contractile function, mitochondrial function and self-regulation. Where after, it will induce cardiomyocyte apoptosis, which can lead to myocardial dysfunction. In this article, the pathogenesis of sepsis-induced myocardial dysfunction (SIMD) were reviewed to further clarify the pathogenesis of SIMD, and provide theoretical basis for subsequent research.
