Lipid peroxidation-induced neurocardiac dysfunction in critically ill patients with septic shock.

CONTEXT: Septic shock's fatal signs include hemodynamic collapse, systemic inflammation, and organ failure. Neurocardiac dysfunctions worsen outcomes, with lipid peroxidation from oxidative stress as a key damage mechanism.

OBJECTIVE

Aim of this study is to investigates how lipid peroxidation in cell membranes generates excessive reactive oxygen species (ROS), leading to mitochondrial damage, cell death, and autonomic dysfunction.

MATERIALS AND

METHODS

Malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE), toxic byproducts, contribute to cardiomyocyte injury, endothelial damage, blood-brain barrier disruption, and altered neuronal signalling. The research analyzes preclinical and clinical data associating sepsis oxidative indicators with poorer cardiac and neurological outcomes.

Results

chronological relationship between oxidative stress, cardiac damage, and neural injury. While the visualisation highlights elevated biomarker levels in critically ill neurocardiac patients.

DISCUSSION AND

CONCLUSION

Early diagnosis, risk classification, and focused treatment for septic shock may benefit from understanding neurocardiac dysfunction and lipid peroxidation.
