Aging Changes In The Heart And Blood Vessels
The "aging process" causes specific cardiovascular changes. This leads to reduced physical and mental ability. Aging is also a risk factor for cardiovascular disease. Scientists a have learned great deal about the interaction of aging with cardiovascular disease related changes and have identified risk factors for both heart and vascular aging, and heart disease.

What Happens To The Inner Layer Of Your Arteries As You Become Older?
The lifetime of an endothelial cell is not infinite, and these cells, like those of your bowel, continuously multiply. However, with advancing age some of these specialized functions of the endothelial cell discussed above become blunted. The self-renewal process weakens.
The endothelial barrier becomes leaky. Signals to vascular smooth muscle cells to regulate their function become altered. Vascular smooth cells as if perceiving endothelial injury migrate to the intima, multiply there and produce collagen, a matrix protein, and other molecules. The addition of these cells and matrix within the sub endothelial space results in intimal thickening.
The intima of older arteries becomes a battleground where multiple reactions occur that are similar to a process of chronic injury. This battleground that occurs with aging provides fertile soil in which the seeds of a disease process called atherosclerosis flourish.
