Key result
Preclinical post-cardiac arrest studies lack multimodal assessments, with 82% relying on single methods like histology.
Why the study?
Post-cardiac arrest brain injury is the main cause of death and disability in cardiac arrest patients, but understanding of the cellular and molecular mechanisms mediating structural and functional damage remains incomplete due to a paucity of relevant preclinical studies.
This narrative review highlights the need for relevant preclinical studies to better understand the cellular and molecular mechanisms of post-cardiac arrest brain injury.

Preclinical post-arrest brain injury models lack multimodal rigor; leaves open development of clinically relevant translational frameworks.
Post-cardiac arrest brain injury (PCABI) is the main cause of death and disability in cardiac arrest (CA) patients [ 1 ]. Our understanding of the processes linking the cellular and molecular mechanisms that mediate brain structural and functional damage after CA is still incomplete, partly because of the paucity of relevant preclinical studies.

Motta et al. (2025) conducted a review in Post-cardiac arrest brain injury. Preclinical assessment methods (histology, imaging, EEG, biomarkers) was evaluated. Most preclinical studies on post-cardiac arrest brain injury rely on single assessment methods like histology, with none fully adopting a clinically relevant multimodal approach combining imaging, biomarkers, and EEG.
