Prognostic Accuracy of DASI for All-Cause Mortality Within 720 days of Follow-Up Compared to Natriuretic Peptide Peptide Concentrations on Admission and to the Voors Score
Time-dependent area under the receiver operating characteristics curve within 720 days of follow-up in patients presenting with acute dyspnea using the DASI, B-type natriuretic peptide (BNP) (A), N-terminal pro-B-type natriuretic peptide (NT-proBNP) (B) levels on admission, and the Voors score (C) with previously described cut-off points (NT-proBNP >4,000 pg/mL, blood urea nitrogen (BUN) >11 mmol/L, age >70 years, hemoglobin <12 g/dL, and beta-blocker use at baseline). Calculated with “timeROC” package R statistical software. AUROC = area under the receiver operating characteristics curve; BNP = B-type natriuretic peptide; BUN = blood urea nitrogen; DASI = Duke Activity Status Index; NT-proBNP = N-terminal pro-B-type natriuretic peptide.
