Findings
poorer neurologic, cardiac arrest
CARDIAC ARREST
In this case-control study, blood phosphorylated tau (p-tau) levels were significantly elevated 24 hours after cardiac arrest and were associated with poorer neurologic outcome. Unlike neurofilament light (NfL) and total tau (t-tau), p-tau levels decreased after 24 hours and were no longer associated with neurological outcome; amyloid-β (Aβ) peptides demonstrated moderate increases and were only weakly associated with neurological outcome.
