VASCULAR AGING

The incidences of heart and vascular diseases increase with age and it is known to be the leading
cause of mortality and morbidity in developed countries. Although aging is a chronological
process, it is known that some environmental factors, chronic diseases and lifestyle may form
and speed up the process of aging, especially of the cardiovascular system. Due to the changes
that occur at structural and molecular levels in the vascular system of the elderly, the function of
the cardiovascular system becomes impaired. Vascular aging is a normal physiological process
which develops gradually along with the age. The most known pathophysiological vascular changes
are the ones beginning at the intimal level such as atherosclerosis. However, the other vascular
pathologies leading to the thickness in media and adventitia and remodeling are also seen
in aging even if atherosclerosis is not present. These changes include an increase in collagen fibers
and covalent bonds, local inflammation, fibrosis, mucous matter storage, a marked decrease
in the elastin composition and the classifications of elastic laminas. Aging related differences
develop independently of the atherosclerosis. They create a cumulative effect by activating the
atherosclerosis with contributions of other factors such as hypertension, dyslipidemia, diabetes
mellitus, renal failure, dietary, genetic and smoking along with aging. When the format and the
mechanism of occurrence of these changes in the growing elderly population are carefully managed
today, we can take a considerable step towards protecting the community from cardiovascular
events and diseases.
