Background. No prospective study has examined whether markers of the central hemodynamics, e.g., central pulse pressure, might be a more robust marker of change in the cardiac hemodynamic load, estimated by the change during the study period of the serum levels of N-terminal fragment B-type natriuretic...

Although the viscoelasticity of large arteries has been extensively investigated, few studies have focused on arterial wall viscosity (AWV) itself and its regulation by the endothelium in vivo. This is of particular importance since AWV is a major source of energy dissipation through the vascular system...
