131 | Arterial walls stiffen with age | — | López-Andrés et al. 2012 | 23172930 | — | — | — | — | — | Age-associated changes in blood vessels include the increase in inflammatory response, cell loss, inability to repair DNA damage, oncogene activation and regulation of telomere-telomerase complex [9-11]. Several age-associated structural, functional, and molecular changes occur in the arterial system. Aging is accompanied with thickening and dilatation of large arteries, extracellular matrix accumulation, calcium deposits, increased vascular stiffness, and endothelial dysfunction [12,13]. These alterations may be attributable to age-related functional changes in vascular cells [12]. Age-related arterial inflammatory phenotype includes increased expression of monocyte chemoattractant protein 1, intercellular adhesion molecule 1, matrix metalloproteinase-2 activity, or transforming growth factor-β expression [14,15]. Age-associated changes in blood vessels include a decrease in compliance, and increase in arterial stiffness and arterial wall thickening as a result of increased vascular calcifications, increased collagen content and cross-linking, and decreased elastin content [16,18].
