  • *A combined BNP/GRACE score was not constructed because BNP was the only independent predictor of the particular endpoint on multivariate analysis.

  • ACS, acute coronary syndrome; BNP, B-type natriuretic peptide; CHF, congestive heart failure; GRACE, Global Registry of Acute Coronary Events; TRI, thrombolysis in myocardial infarction risk index.
