Blood test may forecast brain recovery after cardiac arrest

NCT ID NCT07760636

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This study investigates whether levels of a protein called neurofilament light chain (NFL) in the blood can predict neurological recovery in people who remain comatose after a cardiac arrest. Researchers will measure NFL at several time points over the first week in the ICU and compare these levels with patients' eventual neurological outcomes, ranging from full recovery to severe disability or death. The goal is to see if NFL could serve as a reliable early marker to help guide treatment decisions.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Measurement of neurofilament light chain (NFL) levels in blood at multiple time points after ICU admission
What this could lead to
If NFL levels reliably predict outcomes, doctors could better identify which patients may recover and guide care decisions after cardiac arrest.
What could go wrong
This is an observational study, so it cannot prove cause and effect. NFL levels may not be accurate enough to replace current prognostic methods, and results may vary across different patient groups.
