Figure 4 Natriuretic Peptides and All-Cause Mortality

Admission and discharge proBNP levels were evaluated in patients that met the secondary end point. The box and whisker plots in A demonstrate that patients that suffered all-cause mortality (gray boxes) within 90 days of hospital discharge had significantly higher natriuretic peptide levels at admission compared with those that survived (open boxes). Panel B demonstrates that all 3 natriuretic peptides were also significantly elevated at discharge in patients suffering all-cause mortality (gray boxes) when compared with those that did not meet the secondary end point (open boxes). BNP = B-type natriuretic peptide; other abbreviations as in Figure 1.
