Can common heart-surgery practices trigger delirium? a 5,600-patient hunt for clues.
NCT ID NCT02548975
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This study tracks thousands of heart-surgery patients to identify factors that may increase the risk of postoperative delirium — a state of sudden confusion. Researchers are examining whether medications like statins and beta blockers, the use of a heart-lung machine, or the length of surgery play a role. The goal is to pinpoint modifiable risks that could help prevent delirium in future patients.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If clear risk factors are identified, doctors may adjust care before and during heart surgery to lower the chance of postoperative delirium.
- What could go wrong
- This is an observational study, so it can find links but cannot prove cause and effect. Many factors beyond those measured could influence delirium risk.
