Abstract

The invention provides a non-invasive arteriosclerosis detection method and a device based on a single pulse wave, and relates to the field of arteriosclerosis detection, and the method comprises thesteps: collecting pulse wave signals of main artery points of the whole body of a target object and other positions which are convenient to test, carrying out the preprocessing of the signals, selecting feature points, and carrying out the calculation to obtain feature parameters; combining the physiological information of the object to establish an arteriosclerosis model feature set, screening through correlation analysis to obtain a feature subset, taking the feature subset as input and taking the reference arteriosclerosis degree as output, training by using a machine learning algorithm toobtain an arteriosclerosis model based on the feature subset, and further combining the physiological information of the specific target object to obtain a target arteriosclerosis model; and calibrating the model and completing arteriosclerosis detection. The non-invasive arteriosclerosis detection method is simpler, more convenient, more accurate and more feasible.

Description

technical field [0001] The invention relates to the field of arteriosclerosis detection, and in particular provides a non-invasive arteriosclerosis detection method and device based on a single pulse wave. Background technique [0002] Cardiovascular disease is a major disease that seriously endangers human health. Most cardiovascular diseases have clinical manifestations in the later stages, and there are few opportunities for inspection in the early and middle stages. Arteriosclerosis is the common pathophysiological basis of most cardiovascular diseases. Based on this, accurate detection of arteriosclerosis is the key to the prevention and treatment of cardiovascular diseases. [0003] For arteriosclerosis, the methods for detecting the degree of arteriosclerosis at this stage are mainly divided into invasive and non-invasive methods. The invasive detection method is arteriography. , is not conducive to early detection of arteriosclerosis. Among the non-invasive detecti...
