- Who it is for
- Adults with emergency chest pain when deciding observation, rule-out, or ACS.
- Who it is not for
- Chest pain already clearly non-cardiac. No new ECG score.
- Formula and variables
- HEART is history, ECG, age, risk factors, and troponin. GRACE is age, heart rate, systolic pressure, creatinine, Killip, arrest, ST shift, and marker; the variant stays as on this page. TIMI and TIMI STEMI both exist; this page does not pick a new variant. Killip is pump class. No new chest-pain score.
- Result → next step
- Low risk stays with this page’s rule-out or observation. Once ACS is established, the next page is reperfusion and antithrombotic care. Bleeding uses CRUSADE. Stent duration uses the DAPT page. No loading dose is written.No numeric dose until age, weight, renal function, and pregnancy are all known. Pregnancy is contraindication or caution only.ACS reperfusion / antithrombotic →

Methodology · worked example, guidelines & full notes
Creatinine clearance should be computed by Cockcroft-Gault for consistency with the derivation cohort.
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
- 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.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

FAQ
Frequently asked questions
- What are the limits and cautions when using CRUSADE Bleeding Risk Score?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does CRUSADE Bleeding Risk Score upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is CRUSADE Bleeding Risk Score calculated in practice? Can you show a worked example?
- Inputs: Baseline hematocrit 38 %, Creatinine clearance CrCl 70 mL/min, Heart rate 80 bpm, Systolic blood pressure 130 mmHg, Female Yes, Signs of heart failure at admission Yes, Prior vascular disease Yes, Diabetes mellitus Yes → Result: CRUSADE score 48 pts（Bleeding risk group: High, In-hospital major bleeding (approx.): 11.9%） Inputs: Baseline hematocrit 38 %, Creatinine clearance CrCl 70 mL/min, Heart rate 80 bpm, Systolic blood pressure 130 mmHg, Female No, Signs of heart failure at admission No, Prior vascular disease No, Diabetes mellitus No → Result: CRUSADE score 21 pts（Bleeding risk group: Low, In-hospital major bleeding (approx.): 5.5%）
