Figure 3 Mean Values of RAD and VTI

Mean group values of renal artery diameter (RAD) and velocity time integral (VTI) at baseline (BL) and at 15 min of nesiritide infusion (IN) at a dose of 0.01 µg/kg/min after intravenous bolus administration of 2 µg/kg. Continuous infusion of nesiritide was associated with a progressive significant dilation of the RAD (6.2 ± 0.7 mm to 6.7 ± 0.8 mm, p < 0.001), but at the same time a significant fall in VTI (27 ± 6 cm to 23 ± 15 cm, p < 0.001).
