process that causes telomere decay because of higher rates of leukocyte production; (4) decreased telomerase activity; and (5) increased blood homocysteine that is linked with shorten telomeres.
Certainly, prospective longitudinal studies looking for the correct explanation of shortening of telomere length are required. Telomere increase by telomerase oversecretion does not influence stress-induced senescence [188] but restrains replicative senescence [189–191]. Last, telomere shortening is strongly related with severe atherosclerosis [185].
ATHEROGENESIS
The theory of cellular aging was first used by Hayflick during the 1960s [46,192] and assumes decreasing or stopping of cell division from the structure of arterial wall. In these conditions, VSMCs and elastin are replaced by connective tissue (collagen) that because of its reduced elasticity causes stiffness of aortic wall, conditions in which atherogenesis and calci­fication are favored and occur frequently in the arteries of elderly patients. The Russell Ross hypothesis on atherosclerosis development has been modified three times and established as being a “response to injury hypothesis” [193–195]. This theory states that reactive oxygen species has a significant task in the initiation and progression of atherosclerosis [196].

FIGURE 1.8 Atherosclerosis in the aged artery. Aged endothelial cells express various adhesion molecules (AM), which facilitate the binding as well as transportation of various inflammatory cells, including monocytes (M) and lymphocytes (L) into the intima. OxLDL plays a major role in the formation of foam cells (F). The foam cells secrete several growth factors (GF) and cytokines (C) that lead to increased proliferation of vascular smooth muscle cells (VSMCs). Increased expression of endothelin-1 facilitates atherosclerosis through ET-A receptor activation. The lymphocytes also play a critical role in causing inflammation in the endothelium. Altogether, these changes facilitate the plaque formation in the blood vessels of aged populations [198]. It is an
open access chapter under Attribution 3.0 Unported (CC BY 3.0).
Cellular senescence is involved in vascular disorders, mainly atherosclerosis. It is also established that the initiation of premature senescence through the p53/p21-dependent pathway in human VSMCs [197]. Aging alterations of aortic wall are the result of the concomitantly or sequentially degenerative process, which comprise endothelium, intima, tunica media, and tunica adventitia, and produce: stiffness, calcifications, atheroma, and deformation. The main factor of aging aorta is that ath­erosclerosis undoubtedly starts with endothelium alteration by the adhesion of the molecules that attract inflammatory cells (lymphocytes, monocytes) and penetrate both the tunica media and intima. As a consequence, oxidized low density lipopro­teins by (OxLDL) arise from the foam cells (F). Conversely, these foam cells produce growth factors (GFs) and cytokines (C). Further, these determine the proliferation of VSMCs, activation of endothelin, and lymphocyte infiltration [198,199] (Fig. 1.8).
As already described, atherosclerosis development is reduced by NO [200] that also has an antioxidant effect [201]. The basal NO secretion was examined with NO synthase inhibitor such as N(G)-monomethyl l-arginine and superoxide dismutase [202]. Also, the expression of p22phox is an important element of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, when atherosclerosis is increased [203]. To summarize, NO works by numerous processes to stop the development of atherosclerosis [204].
Senescent endothelial cells exist in human atherosclerosis but not in nonatherosclerotic pathology [205] and support that cellular senescence causes atherogenesis [206]. MMP9 (gelatinase B) is expressed in atherosclerotic lesions [207]. Further, Blankenberg et al. (2003) [208] showed that the C−1562T polymorphism increased promoter activity, adjusted plasma MMP9 levels in patients with CVD, and prognosticated CV events. Finally, vascular inflammation is coordinated by multiple cytokines and chemokines secreted by a plethora of vascular cells and immune cells [209].
Increasing evidence suggests an important role of miRNAs as epigenetic regulators of age-related diseases, including vascular and metabolic diseases [210,211]. Gene expression, cell-type–specific function, and cell–cell communication are regulated by miRNAs, which emerge as important regulators of the cardiovascular system. Because miRNA controls the fate of many genes modulating signaling networks and cell function, targeting a miRNA might be a promising strategy to treat atherosclerotic disease (Fig. 1.9).
CONCLUSIONS
Strategies to prevent the premature senescence of VSMCs could be an effective approach for reducing vascular disease. Therefore, the prevention of arterial aging and its side effects could be made by regular exercise, drugs therapy, or the debat­able newly benefits effects of nutraceuticals.

FIGURE 1.9 miRNAs implicated in atherosclerotic processes. Positive/atheroprotective (in green frame) or negative/atherogenic (in red frame) effects of miRNAs on the atherosclerotic process are shown. Question marks next to miRNAs indicate controversial or contradictory evidence. miRNAs in bold are those reported to be regulated by blood flow/shear stress. Low-density lipoprotein (LDL) diffuses from the blood into the intima and undergoes oxidative modification. Oxidized LDL triggers the expression of leukocyte adhesion molecules by endothelial cells. The initial steps of atherosclerosis include adhesion of blood monocytes to the activated endothelium, their migration into the intima, their maturation into macrophages (or dendritic cells), and their uptake of lipid yielding foam cells. Although fewer in number than macrophages, other leukocyte subsets, such as T cells, also enter the intima and regulate cellular and humoral immune responses. Lesion progression involves the proliferation and migration of SMCs into the intima, as well as increased extracellular matrix protein synthesis, including collagen. Advanced lesions also exhibit intraplaque neovascularization and outward remodel­ing. Abbreviations: LDL, low-density lipoprotein; SMC, smooth muscle cell.

Exercise enhances endothelial function in muscular arteries [213] and decreases the magnitude of reflected waves that come back to the heart [214].
In case of drugs administration for aging prevention, the proportion of elastin fracture could be decreased by therapy with beta-blockers. In monogenic disorders such as Marfan’s syndrome, beta-blockers efficiently decreased arterial stiff­ness [215]. Moreover, the use of statins improves endothelial function, raises NO systemic availability, and raises antioxi­dant and antiinflammatory outcomes [216–218].
Understanding of new molecular therapies that influence the vascular aging mechanisms has important scientific consideration. miRNAs are emerging as new therapeutic targets [219]. As already described, miR-34a is defined as p53-regulated tumor suppressor miRNA, effective in regulating cell cycle ending, apoptosis, and senescence
[220–222].
Moreover, NO decreases atherosclerosis. Therefore, eNOS may have an important function in the control of endothelial cells senescence, being an important aim for a new therapeutic strategy of vascular aging disorders [223].
Phosphodiesterase 1 (PDE1) inhibitors may represent novel therapeutic agents for treating CVDs [224]. Recent stud­ies also identify nicotinamide phosphoribosyltransferase (NAmPRTase or Nampt) as underlying an aging suppression

pathway in smooth muscle cells, with potential relevance to controlling atherosclerosis and possibly other diseases of aging
[225,226]. Moreover, the beginning of endothelial senescence can be anticipated or stopped by some growth factors, as well
as PF/VEGF, TGF-β, IGF, or IL-1α [227–229].
During this decade, nutraceuticals received significant consideration from the part of researchers in aging prevention. Resveratrol (3,5,4-trihydroxystilbene), a polyphenol from red wine has antiaging abilities (preservation of telomere length) could be a helpful nutraceutical therapy in CVD [226]. Furthermore, from the same group of polyphenol, the plant flavo­noids [230–232] showed antiaging properties. For instance, grape seed proanthocyanidin extracts have higher antioxidant properties in comparison with vitamin C, vitamin E, or any other antioxidant [233] and decreases atherosclerosis too [234].
To summarize, CVD is the principal etiology of worldwide mortality and early arterial stiffening is a major promoter to this risk. Increased data of studies underline that arterial stiffness is an independent predictor of cardiovascular disorders. Unfortunately, the accurate molecular pathways managing stiffness are unsuccessfully comprehended and further studies are obviously required.
