Abstract: An object is to provide a method for determining the risk of arteriosclerotic disease which can accurately determine the tendency to develop an arteriosclerotic disease or tendency for advance thereof as the risk of arteriosclerotic disease and can be utilized in prevention and treatment of arteriosclerosis and to provide, for example, a kit for analyzing genetic polymorphism and apparatus for determining the risk of arteriosclerotic disease for use in determination of the risk. A method for determining the risk of arteriosclerotic disease includes a risk evaluation process for evaluating the risk of arteriosclerosis caused by genetic polymorphisms, based on the risk of arteriosclerosis inherent to a combination of plural genetic polymorphisms, from the genotype of a subject on the genetic polymorphisms, in which the combination of plural genetic polymorphisms includes at least one combination of genetic polymorphisms having a significant positive correlation with the carotid arterial intima-media thickness.

Abstract: An apparatus for measuring an intima-media thickness of a blood vessel is disclosed. The apparatus includes: an ultrasound device for outputting digital image data representing an image of the blood vessel produced by scanning the blood vessel with an ultrasound; and a data analyzing device for receiving the output digital image data and calculating the intima-media thickness of the blood vessel according to the received digital image data. The digital image data includes a plurality of luminance values each corresponding to respective one of a plurality of pixels of the image.
