Heartbeat clues may spot hidden surgical dangers
NCT ID NCT04367987
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores whether measuring heart rate variability—the natural ups and downs in heartbeat timing—can help detect complications like leaks or abscesses after planned colorectal surgery. Researchers will monitor patients for a week after surgery and compare heart rate patterns with imaging results. The goal is to find a simple, non-invasive early warning sign for serious post-surgical issues.
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 successful, this could provide a simple, non-invasive way to detect serious complications early after colorectal surgery.
- What could go wrong
- This is an observational study with a small sample size (117 people). The link between heart rate variability and complications may not be strong enough to be clinically useful.
