Early vascular aging (EVA): consequences and prevention
It has often been recognized that a discrepancy exists during the clinical consultation between the chronological age of a patient on the one hand with the signs and symptoms of biological age that can be recorded on the other hand. In cardiovascular medicine this is obvious when a heavy smoker presents with features of early biological aging, for example skin appearance and impaired lung funct...
متن کاملVascular Aging and Diseases: Molecular Mechanisms and Influences
Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...
متن کاملArginase and vascular aging.
Vascular and associated ventricular stiffness is one of the hallmarks of the aging cardiovascular system. Both an increase in reactive oxygen species production and a decrease in nitric oxide (NO) bioavailability contribute to the endothelial dysfunction that underlies this vascular stiffness, independent of other age-related vascular pathologies such as atherosclerosis. The activation/upregula...
متن کاملEarly supernormal retinal oxygenation response in patients with diabetes.
PURPOSE To determine whether the human retinal oxygenation response (deltaPO2) to a hyperoxic provocation is abnormal in patients with type I diabetes. METHODS Magnetic resonance imaging (MRI) was used to measure deltaPO2 during 100% oxygen breathing in patients with type I diabetes who had either no clinically detectable retinopathy (n = 5) or mild to moderate background diabetic retinopathy...
متن کاملHemodynamic Aging as the Consequence of Structural Changes Associated with Early Vascular Aging (EVA).
An increase in peripheral vascular resistance at rest is not routinely observed in healthy older persons, but often associated with increased stiffness of central elastic arteries, as hallmarks of aging effects on the vasculature, referred to as early vascular aging (EVA). In clinical practice, the increased arterial stiffness translates into increased brachial and central systolic blood pressu...
