Perioperative Cardiac Assessment

Cardiac risk before non-cardiac surgery is rarely a single number. Start with an integrated assessment — surgical risk, functional capacity, and cardiac history together. Use RCRI when a validated score is needed. For AF-related decisions, use the condition-specific tools.

Risk score

Cardiac Risk Assessment (RCRI)

Score six clinical predictors to estimate MACE risk and determine whether cardiology evaluation is needed

Use alongside the Risk Navigator when a validated MACE risk score is needed

Calculate RCRI

Condition-specific tools

For atrial fibrillation and anticoagulation decisions

AF / Stroke

CHA₂DS₂-VASc Score

Estimate annual stroke risk in atrial fibrillation and guide perioperative anticoagulation decisions

Calculate CHA₂DS₂-VASc

AF / Bleeding

HAS-BLED Score

Quantify bleeding risk in anticoagulated AF patients and identify modifiable factors before adjusting therapy

Calculate HAS-BLED
