Figure 4 Time Course of Hemodynamic Parameters During the Initial 24 Postoperative Hours

Mean pulmonary artery pressure (A), pulmonary capillary wedge pressure (B), mean arterial pressure (C), central venous pressure (D), cardiac index (E), and systemic vascular resistance (F) at baseline and over the initial 24 postoperative hours in nesiritide (solid lines) and placebo (dotted lines) patients. Points represent mean values and vertical lines represent 1 SEM. The p values are for nesiritide versus placebo comparison using a longitudinal repeated measures analysis of variance model.
