Sudden cardiac arrest is a leading cause of death in the US. A recently developed peptide-based (TAT-PHP) therapy has been shown to improve survival rate and heart metabolism in animal studies. There is a great need to evaluate the effect of the treatment in the brain as the brain is the most susceptible organ following cardiac arrest. We here demonstrated that the recovery of brain perfusion and metabolism is improved in mice with TAT-PHP treatment vs. controls with endogenous perfusion arterial spin labeling MRI and metabolic MRI based on chemical exchange saturation transfer.
