Lactate levels during CPR may predict heart recovery
NCT ID NCT03325452
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether measuring venous lactate (a waste product in the blood) during CPR can help predict if a person's heart will start beating again after a cardiac arrest outside the hospital. Researchers tested lactate levels in 77 adults when emergency teams arrived. The goal is to find a quick, simple way to guide resuscitation decisions, but this is an early pilot study, so more research is needed.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- venous lactate measurement
- What this could lead to
- If successful, this could help doctors better predict who might recover a heartbeat during CPR, potentially guiding resuscitation efforts.
- What could go wrong
- This is a small pilot study with only 77 participants, so results may not apply broadly. Lactate levels are just one factor and may not reliably predict outcomes.
