Figure 4 Outcome in Patients According to Plasma Concentration of NT-proBNP Achieved by 3 Months

Plasma concentrations of amino terminal pro–brain natriuretic peptide (NT-proBNP) of 812 (log: 6.7) and 2,622 (log: 7.8) pg/ml defined the upper and lower boundaries of the middle tercile. The hazard ratio for those in the highest versus lowest tercile was 5.682 (95% confidence interval: 3.819 to 8.455; p < 0.0001). Tr = tercile. BNP = brain natriuretic peptide.
