Coronary artery disease is one of the most common diseases in developed countries and affects a large part of the population of developing countries. Preventing restenosis in patients with implanted stents is an important current medical problem. The purpose of this work is to analyse the viability of bioimpedance sensing to detect the formation of...

... geometry of the model is shown in Figure 1. The values used to implement that geometry, and the electrical properties of the different layers were extracted from [11] and are summarized in Tables 1-3. For the pathological model of the artery, the atheromatous plaque was characterized as a thickening in the muscular layer (where the atherocytes would be found), although with high liposuction content, which pushes the endothelial layer towards the light. ...Context 2
... there are eight electrodes in our system, by changing the excitation and groun electrodes a total number of eight configurations were obtained. All the simulations we carried out on the permanent regime, at an excitation frequency of 10 kHz, with th corresponding values of conductivity and permittivity indicated in Table 1. The value 10 kHz was selected as it was an intermediate value in Tables 2 and 3. ...Context 3

In the field of heart failure, electrical impedance has also Sensors 2024, 24, 3637 2 of 8 been used to monitor body volume [3,4], hemodynamics [9], or the prediction of clinical risks [10]. ...
Heart failure is a severe medical condition with an important worldwide incidence that occurs when the heart is unable to efficiently pump the patient’s blood throughout the body. The monitoring of edema in the lower limbs is one of the most efficient ways to control the evolution of the condition. Impedance spectroscopy has been proposed as an efficient technique to monitor body volume in patients with heart failure. It is necessary to research new wearable devices for remote patient monitoring, which can be easily worn by patients in a continuous way. In this work, we design and implement new wearable textile electrodes for the monitoring of edema evolution in patients with heart failure. Impedance spectroscopy measurements were carried out in 5 healthy controls and 2 patients with heart failure using our wearable electrodes for 3 days. The results show the appropriateness of impedance spectroscopy and our wearable electrodes to monitor body volume evolution. Impedance spectroscopy is shown to be an efficient marker of the presence of edema in heart failure patients. Initial patient positive feedback was obtained for the use of the wearable device.
