Figure 1 Total plasma venous concentrations of natriuretic peptides determined at rest for patients stratified into three groups as a function of the extent of predominantly scarred left ventricular (LV) myocardium on thallium-201 single-photon emission computed tomography (0%, 1%19%, and 20%) and into two subgroups according to age: <65 years (white bars) and 65 years (black bars). The hatched portion of each bar represents the part related to the atrial natriuretic peptide concentration and the open portion to brain natriuretic peptide.
