Figure 3 Event-free survival curves for postdischarge heart failure requiring readmission to hospital in normotensives (dotted and dashed lines; groups NT1 and NT2) and hypertensives (solid lines; groups HT1 and HT2) according to age (top panel), aminoterminal brain natriuretic peptide (N-BNP) (middle panel) and left ventricular systolic volume (LVESV) (lower panel) equal or below (dotted [NT1] and light solid [HT1] lines) and above (dashed [NT2] and heavy solid [HT2] lines) overall median values. Medians: age = 64.1 years; N-BNP 120 pmol/l; LVESV 78 ml. *p < 0.05, **p < 0.01, p < 0.001.
