A detection method for arterial characteristic parameters and a detection method for arterial function and structure

Abstract

The invention discloses a method for detecting arterial characteristic parameters and a method for detecting arterial function and structure. The method for detecting arterial function and structure includes: obtaining the change of blood flow velocity in the artery, the change of the inner diameter of the artery, the change of the outer diameter of the artery, and the change of the inner diameter of the artery within a certain period of time. The data of blood pressure changes; calculate corresponding multiple sets of arterial elastic modulus and arterial characteristic parameters; substitute multiple sets of arterial elastic modulus and arterial characteristic parameters into the pre-built mathematical model to obtain multiple equations; The equation uses the fitting method to obtain the detection results of arterial function parameters and arterial structure parameters. The invention can non-invasively and quantitatively measure the structural parameters and functional parameters of the artery without relying on the cuff, can select multiple parts for detection, and improves the safety, convenience and accuracy of detection.

Description

technical field [0001] The invention relates to the field of arterial detection, in particular to a method for detecting arterial characteristic parameters and a method for detecting arterial function and structure. Background technique [0002] Cardiovascular and cerebrovascular diseases, including atherosclerosis, cerebrovascular sclerosis, and hypertension, are currently one of the factors with the highest mortality rate in the world. Cardiovascular diseases mainly occur in arteries, which are composed of intima, media and adventitia. Among them, the inner membrane has a secretory function, and it mainly secretes nitric oxide molecules to regulate the relaxation of smooth muscle tissue in the middle membrane, while the outer membrane mainly plays a protective role. Vascular lesions include structural changes and functional changes: structural changes are reflected in the hardening of media fibers and smooth muscle tissue, and functional changes are reflected in the weake...

AI Technical Summary

Problems solved by technology

The former cannot evaluate the release of nitric oxide from the endothelium and the relaxation of smooth muscle in response to nitric oxide, but only has the ability to measure the degree of arterial structural stiffness

The latter lacks theoretical guidance and can only qualitatively reflect the functions of endothelium and smooth muscle, resulting in large differences among individuals

In addition, the method for measuring the vasodilation rate under reactive hyperemia is limited to the use of cuff pressurization to induce reactive hyperemia, the operation is complex and lacks standards, and is limited to local detection of upper extremity arteries
