First Claim
Patent Images
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.

Abstract
A method of determining endothelial dependent vasoactivity of a subject, the method is effected by recording pressure-related signals of a plurality of locations adjacent to at least one blood vessel; extracting at least one parameter from the pressure-related signals; and using the at least one parameter to determine a change of at least one characteristic of the at least one blood vessel, the change being representative of endothelial functioning; thereby determining the endothelial dependent vasoactivity of the subject.
