ELN and aneurysm: In contrast, a higher WSS was associated withreduced elastin and smooth muscle cells, leading to stiffer, less compliantaortic walls, eventually resulting in thinning, dilation, and rupture [6, 36].Based on these findings, a predictive model combining clinical baselinecharacteristics, along with morphological and mechanical indicators, wouldsignificantly improve the identification of individuals with a high risk foraortic aneurysm progression and rupture, especially among those with maximumaortic diameters <5 cm [5, 37].
