Figure 1 Atrial natriuretic peptide, brain natriuretic peptide, and cyclic guanosine monophosphate plasma concentrations were significantly elevated in subjects with (black bars) as compared to those without (hatched bars) beta-receptor antagonism. Differences between groups may be overestimated by confounding variables (Table 2). ANP and BNP were in pg·ml1 and cGMP in pmol·ml1. **p < 0.01 vs. subjects without beta-receptor antagonism.

Figure 2 Subgroup analysis for ANP and BNP plasma concentrations in subjects with (black bars) and without (hatched bars) beta-receptor antagonism. RR = arterial blood pressure; Rx = antihypertensive therapy; LAd = left atrial diameter; LVMI = left ventricular mass index; LV-fct. = left ventricular function. *p < 0.05 vs. subjects without beta-receptor antagonism, **p < 0.01 vs. subjects without beta-receptor antagonism.
