Objective To compare the accuracy of the GRACE score, a strong prognosticator in acute coronary syndrome (ACS) that is calculated using conventional cardiac troponin (cTn) assays, with that calculated with high-sensitivity cTn (hs-cTn) and with the combination of the GRACE score with hs-cTn or B-type natriuretic peptide (BNP). Design Prospective international cohort. Settings University Hospital. Patients Patients enrolled in the Predictors of Acute Coronary Syndromes Evaluation prospective study with proven ACS. Main outcome measured The capacity to predict in-hospital mortality, 1-year mortality and combined death/acute myocardial infarction (AMI) at 1 year. Results 370 patients were enrolled (173 with unstable angina and 197 with AMI). In-hospital mortality was 4.1%; 1-year mortality was 12.5%. The GRACE score was significantly higher in patients who died than in those discharged alive (200 (174-222) vs 125 (98-155); p<0.001), and in those who died than in those who survived for 1 year (151 (133-169) vs 104 (85-125); p<0.001). The area under the curve of the GRACE score was 0.87 regarding in-hospital mortality and 0.88 for 1-year mortality; if calculated with hs-cTn, it was 0.87 and 0.88, respectively (p=NS for all comparisons). The addition of hs-cTn to the GRACE score resulted in no increased value, whereas the addition of BNP tended to improve 1-year mortality prediction (p=0.058). Conclusion The GRACE score is accurate for determining both in-hospital and long-term mortality in patients with ACS in the era of hs-cTn. The addition of hs-cTn or BNP to the GRACE score does not significantly improve risk prediction. [ABSTRACT FROM AUTHOR] |
