Ambler Risk Score: Explanation and Clinical Context The Ambler Risk Score is a validated risk model designed to predict operative mortality following cardiac surgery. It incorporates patient demographics, clinical characteristics, and procedural factors into a logistic regression model. Key variables include age, sex, previous cardiac surgery, urgency of procedure, baseline renal function (creatinine), left ventricular ejection fraction (LVEF), and type of surgical procedure.
The calculated score represents the probability of in-hospital mortality, providing clinicians with a quantitative estimate to inform risk stratification, preoperative counseling, and perioperative management.
