Aging-associated changes in vascular activity: a potential link to geriatric cardiovascular disease.
Ischemic cardiovascular disease is a common cause of morbidity and mortality in the United States population over the age of 65. Prior clinical studies have demonstrated that the severity of cardiovascular pathophysiology is increased in older individuals. Both in vitro and in vivo experimental studies have shown that age-associated clinical events parallel changes in vascular function. Aging is associated with systemic as well as cardiac alterations in three basic vascular regulatory functions: vascular tone, hemostasis, and vascular repair/angiogenesis. This article reviews the molecular and cellular events that may contribute to senescent cardiac pathology. Indeed, a better understanding of the biology of aging-associated vascular dysfunction is fundamental for the development of therapeutics targeted for the treatment of cardiovascular disease in older individuals.
