Abstract:

Sepsis-induced myocardial dysfunction (SIMD) is an important cause of poor prognosis of sepsis. Abnormalities in the β-adrenergic receptor (β-AR) signaling pathway such as β-AR receptor desensitization may cause cardiac dysfunction. The mechanisms of β-AR receptor desensitization include receptor resolution, coupling, receptor endocytosis and down-regulation of gene expression, causing a decrease in the number and function of β-AR receptors. This article mainly discusses the relationship between β1-AR desensitization and SIMD, tries to provide a theoretical basis for the treatment of SIMD, and lays a foundation for further research.

Key words: Sepsis, Sepsis-induced myocardial dysfunction, β1 adrenergic receptor, Receptor desensitization
