Methods and apparatus are provided for assessing endothelial function in a mammal. In certain embodiments the methods involve using a cuff to apply pressure to an artery in a subject to determine a plurality of baseline values for a parameter related to endothelial function as a function of applied pressure (Pm); b) applying a stimulus to the subject; and applying external pressure Pm to the artery to determine a plurality of stimulus-effected values for the parameter related to endothelial function as a function of applied pressure (Pm); where the baseline values are determined from measurements made when said mammal is not substantially effected by said stimulus and differences in said baseline values and said stimulus-effected values provide a measure of endothelial function in said mammal.
提供了评估哺乳动物内皮功能的方法和装置。在某些实施例中,这些方法包括: a) 使用袖带对受试者的动脉施加压力,以确定与内皮功能有关的参数的多个基线值,该参数是施加压力(Pm)的函数; b) 对受试者施加刺激,并对动脉施加外部压力 Pm,以确定与内皮功能有关的参数的多个刺激影响值;并对动脉施加外部压力 Pm,以确定与内皮功能有关的参数的多个刺激影响值(作为施加压力 (Pm) 的函数);其中,基线值是在所述哺乳动物基本上不受所述刺激影响时通过测量确定的,所述基线值与所述刺激影响值之间的差异提供了所述哺乳动物内皮功能的测量值。
