CRUSADE Major-Bleeding Risk (NSTEMI)
CRUSADE major-bleeding risk score for NSTEMI: hematocrit, creatinine clearance, heart rate, sex, heart-failure signs, prior vascular disease, diabetes, and a U-shaped systolic-BP term map to in-hospital major-bleeding risk bands.

Example
- Baseline hematocrit
- 35 %
- Creatinine clearance
- 50 mL/min
- Heart rate
- 95 bpm
- Sex
- Female
- Systolic blood pressure
- 85 mmHg
- Signs of heart failure at presentation
- Yes
- Diabetes mellitus
- Yes
Result: CRUSADE 68 — very high bleeding risk (in-hospital major bleeding ~19.5%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Bands
- Very low ≤ 20 (~3.1%), low 21–30 (~5.5%), moderate 31–40 (~8.5%), high 41–50 (~11.9%), very high > 50 (~19.5%).
What you enter
- Baseline hematocrit
- Creatinine clearance
- Heart rate
- Sex
- Systolic blood pressure
- Signs of heart failure at presentation
- Prior vascular disease (PAD or stroke)
- Diabetes mellitus
How this is calculated
- Inputs
- Hematocrit, creatinine clearance, heart rate, sex, heart-failure signs, prior vascular disease, diabetes, and systolic BP (U-shaped).
