Figure 1 Box plots showing median plasma brain natriuretic peptide (BNP) levels (horizontal bars) for normal left ventricular (LV) function versus left ventricular systolic dysfunction (LVSD). Median BNP = 8.5 pmol/l (interquartile range, 8.8) in those with normal LV function versus 16.6 pmol/l (interquartile range, 26.1) in those with LVSD. LVEF = left ventricular ejection fraction.
