Exploring the pathogenesis of sepsis-induced cardiomyopathy: Multilayered mechanisms and clinical responses.

Abstract

Sepsis-induced cardiomyopathy (SIC), as a common complication in the intensive care unit, not only increases the complexity of patient care but also greatly enhances the risk of death. Currently, clinical management of SIC remains challenging, mainly due to the complexity of its pathogenesis and the lack of targeted therapies. Although the specific etiology of SIC is not yet fully understood, existing studies have revealed several vital pathological processes that are intertwined and contribute to the progression of the disease. This narrative review summarizes the existing pathogenesis of SIC, which involves multiple aspects including the inflammatory response, mitochondrial dysfunction, cell death mechanisms, immune regulation, and calcium homeostasis imbalance. Given the multifactorial pathogenesis of SIC, future studies need to explore the interactions between these mechanisms and how to intervene to develop more precise and effective therapeutic strategies to reduce mortality and improve prognosis in patients with SIC.
