Figure 1 Incidence of Worsened Renal Function
Incidence of  20% rise in creatinine (Cr) by discharge or day 7 of the hospitalization. No significant difference was observed in the primary end point of worsened renal function (increase in serum creatinine 20%) (p = 0.85).

Figure 2 Blood Pressure Change During Infusion
Blood pressure change is recorded in reference to the start of the infusion (time = 0). Time "off" refers to 3 h after the infusion was stopped (solid lines = systolic blood pressure change; dashed lines = diastolic blood pressure change; green = placebo; red = nesiritide). p < 0.05 versus placebo at 6 and 12 h for systolic blood pressure, and at 3 h for diastolic blood pressure.
