Caracterización del daño mecánico de la aorta en condición de hipoxia

Abstract: RESUMEN Para evaluar de manera fidedigna el riesgo de ruptura de la aorta – junto a los índices de peligrosidad de enfermedades cardiovasculares u otras condiciones extremas y los efectos de posibles tratamientos – se requiere conocer los mecanismos de daño que conducen a ésta. En este trabajo, se caracteriza el daño mecánico del tejido aórtico en condición de hipoxia, analizando numéricamente su respuesta al ser sujeto a un estado de presurización similar al inducido por un ensayo de acopado hidráulico. El co… Show more

“…Their main results did not reveal significant evidence of changes on the ex-vivo mechanical response of arterial tissue. A similar trend was reported by Bezmalinovic et al (2021) , who addressed the hyperelastic and damage properties of thoracic aortas in the same animal model and treatment as Rivera et al (2020) . Besides, Navarrete et al (2020) determined the effect of Atrial Natriuretic Peptide (ANP) and Cinaciguat on arterial residual strains, considering the same environmental conditions and animal model than Rivera et al (2020) .…”

“…Therein, no significant differences were found on the mechanical parameters from uniaxial-tensile tests, neither on slopes at low and high strain, nor on the transition stress and stretch. Likewise, Bezmalinovic et al (2021) evaluated thoracic aortas of lambs subjected to chronic HAHH and treated with melatonin, finding no significant differences on the uniaxial stress. After analyzing the biomechanical parameters presented in Tables 2 , 3 , it can be seen that there is a tendency for a greater degree of material stiffness in both arterial zones when treatment is applied.…”
