Clinical Context & Significance
Risk stratification is a critical component of perioperative care in cardiac surgery. It allows clinicians to predict the likelihood of mortality and major morbidity, aiding in informed consent, resource allocation, and surgical decision-making.
EuroSCORE II
The European System for Cardiac Operative Risk Evaluation (EuroSCORE II) is a validated logistic regression model designed specifically for cardiac surgical patients. It incorporates 18 patient and operative variables to estimate the risk of in-hospital mortality. It is widely considered the gold standard for risk assessment in Europe.
STS Risk Score
The Society of Thoracic Surgeons (STS) Risk Score is the primary model used in the United States. It provides a highly detailed assessment of risk, covering not only mortality but also specific morbidities such as renal failure, stroke, and prolonged ventilation.
Important Limitation: Models like EuroSCORE II and STS provide population-level probabilities. They are clinical tools intended to support, not replace, the clinical judgment of the multifaceted cardiac surgical team.
