Parsonnet Score: Explanation and Clinical Context The Parsonnet Score is a widely used cardiac surgical risk stratification tool developed to predict operative mortality in patients undergoing cardiac surgery. It assigns points based on preoperative risk factors, including age, sex, history of myocardial infarction, congestive heart failure, and urgency of the procedure. The cumulative score correlates with the estimated operative mortality, helping clinicians assess surgical risk and guide perioperative management.
