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 estim
PROMISS Score (Postoperative Mortality): Explanation and Clinical Context The PROMISS score is a validated tool to predict 30-day postoperative mortality in adult surgical patients. It incorporates patient age, ASA physical status, emergency surgery, cardiac failure, and renal failure. The model uses logistic regression to calculate the predicted probability of postoperative death, allowing clinicians to identify hig
PROVE-HF Surgical Score: Explanation and Clinical Context The PROVE-HF Surgical Score is a prognostic tool designed to predict postoperative mortality in patients with chronic heart failure undergoing major non-cardiac surgery. This score incorporates four clinical parameters: estimated glomerular filtration rate (eGFR), left ventricular ejection fraction (LVEF), hemoglobin levels, and brain natriuretic peptide (BNP)
