Abstract

Arterial stiffness, particularly aortic stiffness (AoS), is associated with an increased risk of cardiovascular disease. Endovascular repair for abdominal (EVAR) and thoracic (TEVAR) aortic disease may increase AoS. This study protocol aims to assess changes in AoS before and after interventions for aortic disease. Patients scheduled for EVAR or TEVAR during a three-year period will be enrolled. An indirect AoS indicator, carotid-to-femoral pulse wave velocity (cf-PWV) will be measured non-invasively using applanation tonometry and reported with others perioperative data before and after the endovascular treatment. Moreover, cardiological data will be collected through echocardiography. Fifty EVAR and 50 TEVAR will be enrolled. We will primarily analyze changes in cf-PWV. To ensure the reliability of our findings, we will also include supplementary data such as clinical information, morphological data, and functional echocardiographic data. By examining AoS modifications before and after endovascular aortic repair, this study aims to enhance our understanding of how arterial stiffness changes following endoprosthesis deployment. The findings from the applied protocol are expected to be informative for innovative graft designs with minimized mechanical mismatch with the aortic wall and with improved vascular hemodynamic, aligning with the current trend in improving patient outcomes. Moreover, understanding these modifications is important for predicting and improving long-term cardiovascular outcomes in patients undergoing such interventions.
