Figure 2 Natriuretic Peptide Characterization
Plasma B-type natriuretic peptides were compared with the characteristics of the 164 unique individuals hospitalized for congestive heart failure (CHF). The box and whisker plots in A and B demonstrate that pro-B-type natriuretic peptide (proBNP) is independent of age and body mass index (BMI). Panel C suggests that proBNP levels are also independent of serum creatinine and corresponding renal insufficiency. Panel D demonstrates that proBNP levels are unchanged in patients with systolic or diastolic dysfunction.
