Evaluation of the CRUSADE Risk Score for Predicting Major Bleeding in Patients with Concomitant Kidney Dysfunction and Acute Coronary Syndromes

Background: Kidney dysfunction (KD) has been associated with increased risk for major bleeding (MB) in patients with acute coronary syndromes (ACS) and may be in part related to an underuse of evidence-based therapies. Our aim was to assess the predictive ability of the Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA guidelines (CRUSADE) risk score in patients with concomitant ACS and chronic kidney disease. Methods: We conducted a retrospective analysis of a prospective registry including 1,587 ACS patients. In-hospital MB was prospectively recorded according to the CRUSADE and Bleeding Academic Research Consortium (BARC) criteria. KD was defined as an estimated glomerular filtration rate 0.3). Conclusions: The CRUSADE risk score shows a lower accuracy for predicting in-hospital MB in KD patients compared to those without KD.
