Figure 3 Natriuretic Peptides and Cardiac Death

Admission and discharge plasma natriuretic peptide levels were evaluated in patients that met the primary end point. The box and whisker plots in A demonstrate that patients that suffered a cardiac death (gray boxes) had significantly higher plasma natriuretic peptide levels at admission compared with those that did not have an event (open boxes) within 90 days of hospital discharge. Panel B demonstrates that B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptides (NT-proBNP) levels were also significantly elevated at discharge in patients suffering a cardiac death (gray boxes) when compared with those that did not (open boxes).
