Blocking blue light at night after heart surgery
Part of Brain & nervous system clinical trials.
This trial tests whether reducing blue light at night after certain planned heart surgeries helps protect mood, thinking, and recovery. If you have no history of major mental health problems or organ problems, you may be able to join the study.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are having planned (not emergency) heart surgery such as bypass (CABG), valve replacement (AVR), or valve repair/replacement (MVR/other listed combinations), or SAH
- You do not have a diagnosed psychiatric disorder (including depression or anxiety)
- You do not have dementia or any known thinking/memory problems (cognitive deficit)
- You do not have major organ failure (for example, kidney, liver, or other organs), and your kidney test is not severely abnormal
- You do not have conditions that raise transfusion risk, clotting disorders, active infection, or immune disorders
- You meet surgery safety thresholds (including no prior cardiac surgery, no combined heart operations, and left ventricular strength not too low)

This study tests if exposing patients to green light after laparoscopic or robotic surgery can help reduce pain and improve recovery. You may be eligible if you are staying in the hospital for at least two days after your surgery.
This study looks at ways to predict and prevent complications in older adults after major heart or blood vessel surgery. It may help reduce risks and improve recovery.
This trial tests whether using bright light at the right time during and after heart surgery helps patients recover more comfortably. It focuses on people having a specific type of open-heart surgery and checks certain heart rhythm and safety factors.
This study tests whether a combination of sleep therapy, brain games, and light exercise before heart surgery can help prevent confusion or disorientation (delirium) after the operation. Participants will be asked to use a tablet and fitness tracker daily for about an hour before their surgery.
This study tests a new way to monitor blood flow to the brain during heart surgery. The goal is to see if this can help protect the brain and reduce thinking problems after surgery.
This study tests whether wearing an eye mask and earplugs in the hospital after heart bypass surgery helps improve sleep and reduce confusion (delirium). If you have had this surgery, the study will see if these simple items can help you rest and recover more clearly.
