This free calculator estimates your predicted surgical risk using three validated models used by cardiac surgery programs worldwide. The STS Predicted Risk of Mortality (STS PROM) is the gold standard in North America, developed from the Society of Thoracic Surgeons National Database of over 7 million procedures. EuroSCORE II, published in 2012 by Nashef et al., is the leading European model using 18 patient, cardiac, and operative risk factors. The WhiteGloveMD Composite integrates both scores with frailty assessment, biomarker data, and coronary complexity for a more complete risk picture.
Knowing your risk score is the first step toward informed surgical decision-making. Enter your clinical variables below for real-time risk estimates, or scroll down to learn how these scores are used by Heart Teams to guide care.
This calculator uses published STS regression methodology with approximated coefficients. For your official STS PROM score, consult your surgical team or visit sts.org.
