STS Risk Score
Also written as: STS — Society of Thoracic Surgeons
Society of Thoracic Surgeons risk calculator predicting operative mortality and morbidity for cardiac surgery in elderly patients.
Full Definition
The Society of Thoracic Surgeons (STS) Risk Score is a validated risk prediction model that estimates the probability of operative mortality and major morbidity for patients undergoing cardiac surgery. This scoring system is particularly relevant in geriatric cardiology for risk stratification of elderly patients being considered for cardiac procedures. The calculator incorporates multiple patient-specific variables including age, comorbidities, functional status, and procedure type. STS scores help guide treatment decisions, inform consent discussions, and identify patients who may benefit from alternative approaches such as transcatheter interventions.
Usage
Usage note: Express as percentage; specify whether referring to mortality or morbidity risk.
