ABSTRACT The aim of the study was to review the features of the functional state of the kidneys in patients with cardiopathy, betting on the presentation of the components of the metabolic syndrome. For the research we examined 197 male patients with chronic heart condition (CHF) of ischemic genesis of II-III functional class (FC) in line with NYHA. Metabolic syndrome in patients with chronic heart failure HFmrEF exacerbates impaired renal function, which has developed together of the most pathogenetic links in chronic heart condition. it's been established that because the metabolic syndrome progresses (attachment of T2DM to other components of the metabolic syndrome), the phenomena of functional kidney failure increase. Evidence of the importance of the metabolic syndrome within the nature of the clinical manifestations of chronic coronary failure HFmrEF is that the established dependence of the identified disorders on the severity of the metabolic syndrome.
