[Influence of early stage of chronic renal disease on risk of cardiac diseases and stroke].

Cardiovascular diseases are the main cause of death among people with kidney diseases. The early stage of chronic kidney disease, with mild decrease of glomerular filtration rate (GFR) and small increase of creatinine concentration in serum and/or occurrence of microalbuminuria, is related to the increase of cardiovascular morbidity and mortality. Kidney insufficiency is also independently connected with the risk of stroke. Patients with early stage of kidney insufficiency should be qualified as those in a cardiovascular high risk group.
