Evaluation Of Vascular Disorder Effect On Bioimpedance Values Using Finite Element Method

9 pagesPublished: May 15, 2020

Abstract

Cardiovascular diseases are the first cause of death globally: more people die annually from these diseases than from any other causes. These diseases are a group of disorders of the heart and blood vessels that appears silently but lead to many serious consequences for life. Vascular diseases including atherosclerosis, aneurysm, peripheral artery disease... affect the arteries, veins, or capillaries throughout the body and around the heart. Therefore, assessment of the quality of blood vessels early is extremely necessary in order to prevent cardiovascular diseases. Bioimpedance analysis is a non-invasive, safe, and low-cost technique that is widely used for diagnosing various diseases. This study conducts a novel method to evaluate the status of the blood vessels in two cases: stenosis and aneurysm based on bioimpedance signals. A 3D model of the forearm with several layers (skin, fat, muscle, bone, and blood vessel) and electrodes is simulated by using Comsol Multiphysics software. The electric impedance in different vascular conditions is examined. The results show that vessel impedance changed substantially because of vascular disorders. The bioimpedance signals vary according to the sizes of plaque and aneurysm wall. Consequently, bioimpedance analysis is reliable to detect vascular diseases and able to be applied in the near future.
