RISK-E (Endocarditis Surgery Mortality) Calculator

  • Age (years)
  • Renal Failure (1=yes, 0=no)
  • NYHA Class III-IV (1=yes, 0=no)
  • Diabetes Mellitus (1=yes, 0=no)
  • Critical Preoperative State (1=yes, 0=no)
  • Prosthetic Valve Endocarditis (1=yes, 0=no)
  • Emergency Surgery (1=yes, 0=no)
  • Paravalvular Complication (1=yes, 0=no)
  • RISK-E (Endocarditis Surgery Mortality) Score: Explanation and Clinical Context
    The RISK-E score is a validated risk prediction tool for estimating operative mortality in patients undergoing surgery for infective endocarditis. It uses preoperative clinical variables, including age, renal failure, NYHA class III-IV heart failure, diabetes mellitus, critical preoperative state, prosthetic valve involvement, emergency surgery, and paravalvular complications.
    The score applies a logistic regression formula to provide a predicted mortality percentage, aiding clinicians in surgical risk assessment, patient counseling, and perioperative planning.
