Age-related changes of renal haemodynamics
Normal human ageing occurs with morphological and functional changes in nearly all organ systems, and the kidney is no exception to this rule. Even in individuals without primary renal disease, kidney structure and function deteriorate with senescence to some extent. Recent studies have revealed, however, that age-related renal changes are accelerated by co-morbid conditions such as hypertension, atherosclerosis and heart failure [15].
Results from the seminal Baltimore Longitudinal Study on Aging and from several cross-sectional studies have shown that the decrease of glomerular filtration rate (GFR) in healthy elderly subjects is less than was thought previously [1,3,6,7]. In some
