Figure 1 Hemodynamic data in patients with CHF as compared with healthy subjects before (B) and after (BNP) infusion of BNP (15 ng/kg per min). *p < 0.05 between groups; p < 0.05 after BNP infusion versus baseline; p < 0.05 response to BNP between different groups. BNP = brain, or b-type, natriuretic peptide; CHF = congestive heart failure; CI = cardiac index; DP = diastolic pressure; HR = heart rate; PAP = pulmonary artery pressure; PCWP = pulmonary capillary wedge pressure; RA = right atrial (pressure).
