Background: Beta-trace protein (BTP) and cystatin C (CysC) are novel biomarkers of renal function. We assessed the ability of both to predict major bleeding (MB) in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS), compared to other renal function parameters and clinical risk scores. Methods and Results: We included 273 patients. Blood samples were obtained within 24h of admission. The endpoint was MB. During a follow-up of 760 days (411–1,098 days), 25 patients (9.2%) had MB. Patients with MB had higher concentrations of BTP (0.98mg/L; 0.71–1.16mg/L vs. 0.72mg/L, 0.60–0.91mg/L, P=0.002), CysC (1.05mg/L; 0.91–1.30mg/L vs. 0.90mg/L, 0.75–1.08mg/L, P=0.003), higher CRUSADE score (39±16 points vs. 29±15 points, P=0.002) and lower estimated glomerular filtration rate (eGFR; 66±27 vs. 80±30ml·min–1·1.73m–2, P=0.02) than patients without MB; there was no difference in creatinine level between the groups (P=0.14). After multivariable adjustment, both were predictors of MB, while eGFR and creatinine did not achieve statistical significance. Among subjects with eGFR >60ml·min–1·1.73m–2, those with elevated concentrations of both biomarkers had a significantly higher risk for MB. Net reclassification indexes from the addition of BTP and CysC to CRUSADE risk score were 38% and 21% respectively, while the relative integrated discrimination indexes were 12.5% and 3.8%. Conclusions: Among NSTE-ACS patients, BTP and CysC were superior to conventional renal parameters for predicting MB, and improved clinical stratification for hemorrhagic risk.
