↑ NE blood levels in AAA patients compared to non-AAA controls [108,110]elastin-derived peptides induced NE release in AAA patients > aortic occlusive disease > healthy controls [108,109,110]↑ circulating NE-derived fibrin degradation products in AAA patients correlated with AAA and ILT volume and ILT mechanical stress [115,116]. This evidence concerns the gene ELN and triple-A syndrome.
