CARDIAC SURGERY

This study tests a simple, non-invasive ear stimulation technique to prevent acute kidney injury in people having heart surgery with a heart-lung machine. About 152 adults will receive either real or fake stimulation before and after surgery. The goal is to see if this approach r…

This study looks at whether a 30-minute music session can help adults recover from heart surgery. Researchers will measure stress hormones, anxiety, pain, and vital signs in 120 patients. The goal is to see if music, a simple and safe activity, can improve early recovery after ca…

This study tests whether a 12-week exercise program (aerobic and strength training) helps people recover after heart surgery, such as valve replacement or bypass. 76 adults will be split into two groups: one does the program, the other gets usual care. Researchers will measure qu…

This study planned to see if two monitoring tools—an ultrasound probe in the esophagus and a skin sensor that measures oxygen levels—could help doctors predict kidney injury early in children having heart surgery. The goal was to find a faster way to spot kidney problems during t…

This study looks at a specific lung measurement called airway opening pressure in 196 adults recovering from heart surgery. The goal is to find out how often this pressure is high and if it leads to breathing problems. By understanding this, doctors hope to tailor breathing machi…

This research looks at why people with multiple long-term health problems (like kidney or lung disease) are more likely to have organ damage and slower recovery after heart surgery. The team will study heart cells and data from over 3,000 patients to understand the biological cha…

This study looks at whether left-handed heart surgeons learn suturing skills better when taught by a left-handed instructor instead of a right-handed one. About 30 left-handed surgeons and residents will take part during a medical conference. They will be randomly assigned to eit…

This study looks at how different breathing machine settings during heart surgery affect patients' recovery. Over 5,500 adults having planned heart surgery with a heart-lung machine are included. The goal is to see if using low air volume and avoiding too much oxygen reduces lung…

This study looks at 40 adults having heart surgery to see if a less invasive method (mini-incision) helps preserve breathing and muscle strength better than traditional open-chest surgery. Participants will have lung function, muscle strength, and walking tests before and after s…

This study compares two common anesthesia drugs, ketamine and propofol, given at the start of heart surgery to see which one better protects the kidneys from injury. About 200 adults having complex heart surgery at Mayo Clinic will take part. The goal is to find out if ketamine r…
