Hidden nerve damage may disrupt Heart's electrical activity during surgery
NCT ID NCT07684768
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This study looks at whether cardiac autonomic neuropathy (nerve damage that affects heart rate control) changes the heart's electrical recovery time (QT interval) in people having coronary artery bypass surgery. Researchers will test nerve function before surgery and measure heart rhythm at several points during and after the operation. The goal is to see if patients with this nerve condition are more likely to have dangerous heart rhythm changes during surgery.
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 cardiac autonomic neuropathy is shown to prolong QT intervals during surgery, it could help doctors identify high-risk patients and adjust monitoring or care to prevent dangerous heart rhythms.
- What could go wrong
- This is a small observational study, not a treatment trial. It can only suggest a link, not prove cause and effect. Results may not apply to all heart surgery patients.
