[Specificity of estimation and prognostic value of glomerular filtration rate in older age groups with cardiovascular pathology.].

The demographic situation in recent decades has been characterized by a progressive increase in the proportion of older age groups in both developed countries and the Russian Federation. The main contribution to morbidity and mortality of people over 60 years of age is made by diseases of the circulatory system. Early development and progression of cardiovascular diseases contributes to kidney dysfunction, often developing against the background of morphological changes occurring with age in the kidneys, called "senile kidney". Reduction of glomerular filtration rate in elderly patients is not mandatory and in most cases occurs as a result of an existing pathological process. The combined effect of changes in GFR and cardiovascular disease on the prognosis of older patients remains poorly understood, which determines the relevance of the study of chronic kidney disease in geriatric patients.
