Discussion

Experiment reveals increased cardiac dysfunction during sepsis in older mice, suggesting mitochondrial dysfunction exacerbates injury.

Mitochondrial alterations contribute to increased cardiac dysfunction in aging during sepsis.
Older mice showed greater cardiac contractility reduction and functional depression post-sepsis compared to younger ones.
Increased oxidative phosphorylation protein levels were observed in older mice as a compensatory response.
Understanding mitochondrial responses in aging can inform treatments for sepsis-related cardiac issues.

Du et al. (2025) studied this question.
