CRUSADE Bleeding Score
Estimates major bleeding risk in patients with non-ST-segment elevation infarction.
When to use
Adults with non-ST-segment elevation myocardial infarction before defining antithrombotic strategy.
Pearls and pitfalls
- The score uses hematocrit, creatinine clearance, heart rate, systolic pressure, sex, heart failure, vascular disease and diabetes.
- Creatinine clearance is estimated with Cockcroft-Gault, with a 0.85 factor for women.
- Diabetes scores 6 points; female sex scores 8; heart failure scores 7.
- The score guides antithrombotic choice and dose but does not replace clinical judgment.

Formula
Add points for hematocrit, creatinine clearance, heart rate, sex, heart failure, vascular disease, diabetes and systolic pressure.
Evidence
Score derived and validated in acute coronary syndrome cohorts to predict in-hospital major bleeding.
