This study compares two different blood vessels used as grafts during heart bypass surgery in women. Researchers want to see whether using a vein from the leg (with a special 'no-touch' technique) or an artery from the arm stays open better over time. The goal is to improve long-…

This study is testing whether wearable devices like Fitbits can help detect complications earlier in patients recovering from heart or chest surgery. About 1,200 patients will wear a device before and after their operation, and a computer program will analyze their activity and s…

This study is testing if fluvoxamine, an existing medication, can prevent delirium (sudden, severe confusion) in older adults after non-heart, non-brain surgery. Researchers believe inflammation after surgery may cause delirium and that fluvoxamine might reduce this inflammation.…

This study is testing whether two over-the-counter supplements, CoQ10 and Glutathione, can prevent kidney injury in patients undergoing elective heart bypass surgery. About 242 participants will receive either the supplements or a placebo starting the day before surgery and conti…

This study is testing whether using a lighter level of general anesthesia during major surgery can help protect older adults' brains. It compares 'light' anesthesia to the usual 'deep' anesthesia to see if the lighter approach reduces post-surgery confusion (delirium) and long-te…

This study aims to understand how often heart problems and other complications happen after same-day outpatient surgery. Researchers will follow 15,000 patients for 90 days after their procedures to track their health. The goal is to identify risk factors and create better tools …

This study aims to understand what complications patients experience in the year following ankle surgery. Researchers will follow 150 adults who undergo arthroscopic ankle surgery, checking in with surgeons and physical therapists at regular intervals. The goal is to document all…
