Glomerular Filtration Rate in Renal Damage

Renal function is mainly represented by the glomerular filtration (GF), which is dependent on the number and function of the nephrons. Glomerular filtration declines progressively after the third decade with a progressive loss of 1 % per year. In addition to diseases producing direct damage in the glomerular structures, high blood pressure values, diabetes, and dyslipidemia are the main factors increasing the rate of GF decline over the years. Other functional parameters of the kidney such as renal plasma flow or tubular functions are not measured in daily practice in hypertension and are not related to risk for cardiovascular disease (CVD).
