Metabolic strategies for reperfusion injury after cardiac arrest: a review
This narrative review examines metabolic approaches intended to reduce reperfusion injury after resuscitation from cardiac arrest. The authors describe encouraging laboratory findings but note that controlled trials have not shown positive outcomes sufficient to support routine clinical use.
- Reviews metabolic approaches to post-arrest reperfusion injury.
- Laboratory findings have not translated into positive controlled-trial outcomes.
- Timing, treatment windows and dosing remain trial-design challenges.
Reperfusion injury can occur when spontaneous circulation is restored after cardiac arrest, adding to the risk of tissue and neurological damage. This narrative review surveys strategies aimed at limiting that injury, including reducing metabolic demand through temperature control or mitochondrial electron-chain inhibition, using mitochondria-targeted antioxidants, and providing specific energy substrates early after resuscitation.
The authors describe encouraging results in laboratory studies but report that translation into routine care has been limited by a lack of positive outcomes in controlled trials. They identify challenges including timely delivery, defining effective treatment windows and optimising doses. The review also discusses mechanisms, non-clinical outcomes, the limited human evidence and trial-design issues. It does not establish a metabolic strategy as effective for routine post-arrest care. The authors disclose that two are developing thiometallates for ischemia-reperfusion injury.
