A bedside score that could foretell heart surgery risks

This study asks whether a simple bedside score, called the Vasoactive Inotropic Score (VIS), can help predict which adults are at higher risk of complications after heart surgery using a heart-lung machine. The score is calculated from the doses of heart-support medications a patient is already receiving, so no extra tests are needed. Researchers will measure VIS at several points in the first two days after surgery in 617 adults undergoing procedures like valve repair or coronary bypass. The goal is to see if early VIS readings can flag patients more likely to experience serious issues such as kidney injury, stroke, or the need for extra circulatory support.
