Figure 1 ROC Curve for Cutoff Values of BNP Levels at 6 Months Post-Discharge
A B-type natriuretic peptide (BNP) level of 190 pg/ml had the best compromise between sensitivity (96%) and specificity (76%) for predicting readmission for decompensated heart failure or sudden death. ROC = receiver-operating characteristic. Area under curve = 0.91.
