Can a laser beam speed recovery from heart bypass surgery?
NCT ID NCT07699679
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This trial investigates whether photobiomodulation—applying low-level laser light to the surgical wound—can improve healing and reduce complications after coronary artery bypass grafting (CABG). It compares two methods of harvesting the saphenous vein (the conventional technique and the no-touch technique) in 292 heart disease patients. The study measures wound healing, functional capacity, and overall recovery. If successful, this approach could offer a simple, non-drug way to enhance postoperative outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Photobiomodulation therapy (low-level laser light)
- What this could lead to
- If effective, this light therapy could speed wound healing and reduce complications after heart bypass surgery, improving recovery.
- What could go wrong
- This is a mid-sized trial testing a device, not a drug. The effect may be small or no better than placebo, and results may not apply to all patients.
