1. A system for determining endothelial dependent vasoactivity of a subject, the system comprising:

  • an arrangement of sensors for recording pressure-related signals of a plurality of locations adjacent to at least one blood vessel, said at least one blood vessel being in at least one organ of said subject;

    a processing unit configured to extract at least one parameter from said pressure-related signals, anda spectral analyzer configured for analyzing said at least one parameter and obtaining a frequency decomposition of said at least one parameter, said frequency decomposition being representative of the endothelial dependent vasoactivity of the subject;

    wherein said at least one parameter comprises a parameter selected from the group consisting of elapsed time between two successive peaks of one or more of said pressure-related signals, and amplitude of one or more of said pressure-related signals.
