Figure 1 Kaplan-Meier analysis of the 12-month, event-free survival rates of 165 patients with congestive heart failure treated with beta-blockers and 243 patients without beta-blocker treatment.
Figure 2 Frequency of combined end points within 12 months in congestive heart failure patients with (black bars) and without (white bars) beta-blocker treatment, stratified by frequently applied cut-off values for peak oxygen consumption (peakVO2) and left ventricular ejection fraction (LVEF) or by tertiles of norepinephrine and N-terminal pro-brain natriuretic peptide (NT-proBNP) (all p < 0.05).
Figure 3 Kaplan-Meier analyses of patients with congestive heart failure treated with or without beta-blockers, stratified by (A) peak oxygen consumption (peakVO2) (> or 14 ml/min per kg), (B) left ventricular ejection fraction (LVEF) (> or 20%) and the median values of (C) norepinephrine and (D) N-terminal pro-brain natriuretic peptide (NT-proBNP) (all p < 0.0001).
