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

RCRI 0: Very low cardiac risk (0.4 %)

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

RCRI 1: Low cardiac risk (0.9 %)

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

RCRI 2: Elevated cardiac risk (7 %)

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

RCRI 3+: High cardiac risk (11 %)

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.
