🩸 CRUSADE Bleeding Risk Score
The CRUSADE score estimates baseline in-hospital major-bleeding risk in NSTE-ACS patients.
CRUSADE Bleeding Risk Score
Baseline hematocrit (%)
Creatinine clearance CrCl (mL/min)
Heart rate (bpm)
Systolic blood pressure (mmHg)
Female
Signs of heart failure at admission
Prior vascular disease
Diabetes mellitus
When to use
Enter hematocrit, creatinine clearance, heart rate, systolic BP, and four categorical features; the tool returns the score, risk band, and estimated bleeding rate.
How it works
Weighted points from hematocrit, CrCl, heart rate, and systolic BP plus female sex (8), heart-failure signs (7), prior vascular disease (6), and diabetes (6). Strata: ≤20 very low to >50 very high.
Key points
- For high-risk scores, prefer radial access and dose-adjusted antithrombotics to mitigate bleeding (original synthesis · not guideline verbatim).
- Creatinine clearance should be computed by Cockcroft-Gault for consistency with the derivation cohort.
- Bleeding risk must be weighed against ischemic risk rather than used to withhold indicated antithrombotic therapy outright.
