Revised Cardiac Risk Index (RCRI / Lee Index)
Predicts perioperative major adverse cardiac events (MACE) for non-cardiac surgery. Guides preoperative optimisation and monitoring.
Score interpretation
Major cardiac complications (MI, pulmonary oedema, VF / primary cardiac arrest, complete heart block) in the Lee 1999 validation cohort: 0.4 %.
→ Proceed with surgery; routine monitoring
Major cardiac complications (MI, pulmonary oedema, VF / primary cardiac arrest, complete heart block) in the Lee 1999 validation cohort: 0.9 %.
→ Proceed; consider cardiology review if new symptoms
Major cardiac complications (MI, pulmonary oedema, VF / primary cardiac arrest, complete heart block) in the Lee 1999 validation cohort: 7 %.
→ Cardiology review; echocardiogram if poor functional capacity; preoperative beta-blocker if on chronic therapy
Major cardiac complications (MI, pulmonary oedema, VF / primary cardiac arrest, complete heart block) in the Lee 1999 validation cohort: 11 %.
→ Cardiology assessment; consider delaying elective surgery for optimisation; discuss risks/benefits
Interpretation bands for the RCRI. Apply clinical judgement and local guidance.
