Frequently asked questions

What is the CRUSADE bleeding score?

A score predicting the risk of major in-hospital bleeding in patients with non-ST-elevation acute coronary syndrome.

How is the CRUSADE score interpreted?

Risk bands: ≤ 20 very low, 21–30 low, 31–40 moderate, 41–50 high, > 50 very high probability of major bleeding.

How is it used clinically?

It informs the bleeding-risk side of the ischemia–bleeding trade-off, e.g., choice and intensity of antithrombotics and access site.

Was CRUSADE validated for STEMI?

It was derived in NSTE-ACS; performance in STEMI and with radial access / contemporary therapy is less well established.
