Subherwal et al developed the CRUSADE bleeding score to identify a patient at risk for major in-hospital bleeding following therapy on non-ST-segment elevation myocardial infarction. The authors are from Washington University, Duke University, University of Cincinnati and Pennsylvania Hospital.
CRUSADE = Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHH guidelines.
Parameters:
(1) baseline hematocrit in percent
(2) estimated creatinine clearance in mL per minute (Cockcroft-Gault)
(3) heart rate in beats per minute
(4) gender
(5) signs of congestive heart failure (CHF) at presentation
(6) history of prior vascular disease (stroke or peripheral artery disease)
(7) history of diabetes mellitus
(8) systolic blood pressure in mm Hg
