STS Adult Cardiac Surgery Risk Score: Explanation and Clinical Context The STS Adult Cardiac Surgery Risk Score provides an evidence-based estimation of perioperative mortality and morbidity in adults undergoing cardiac surgery. It incorporates patient-specific clinical variables such as age, sex, renal function, history of heart failure, previous cardiac surgery, and type of surgical procedure. The score is derived from logistic regression models validated in large multicenter STS databases, reflecting real-world surgical outcomes.
Predicted risk assists clinicians in preoperative counseling, surgical decision-making, and resource allocation, enabling individualized risk stratification.
