Pressure × stiffness relationship with aging. (A) Arterial stiffness of TDA was significantly (p < 0.01) increased with age. (B) Absolute pressure-diameter change in young vs aged aortic segments. Statistical analyses: Two-way ANOVA, repeated measures with Sidak post-hoc test for multiple comparisons. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. n = 6 per group. Ep Petersons elastic modulus, PE phenylephrine, DEANO 2-(N,N-diethylamino)-diazenolate-2-oxide sodium salt hydrate.
