Introduction. Renal dysfunction is the leading cause of significant comorbidities associated with an unfavorable clinical prognosis. It should be noted that chronic heart failure dramatically impairs the quality of life of patients and increases the risk of mortality. The mortality rate during the year is 15–50 %. The main factor in the deterioration of renal function is a decrease in cardiac output and venous stasis. Decreased cardiac output decreases renal perfusion and thus glomerular filtration rate. Venous stasis causes an increase in pressure in the external arterioles and capillaries of the glomeruli.
The aim of the study – to learn the kidney dysfunction indices in patients with chronic heart failure (CHF).
Research Methods. 96 patients with postinfarction cardiosclerosis complicated by CHF at the age of 40–60 years were examined. Patients were divided into two groups by functional class (FC) of CHF according to the New York Heart Association (NYHA). The creatinine level was determined for all patients, and the glomerular filtration rate (GFR) was calculated using the formula MDRD (Modification of Diet in Renal Disease Study). Determination of enzymes in urine – alanine transferase (ALT), aspartate transferase (AST), alkaline phosphotase (ALK phos), cholinesterase by spectrophotometric method.
Results and Discussion. GFR < 60 ml/min/1,73m2 was marked in 33.3 % of patients with II FC CHF and 66.7 % of patients with III FC CHF. The study of fermentation indices in patients with CHF depending on the functional state of the kidneys revealed that in patients with GFR <60 ml/min/1,73m2, among which the patients with III FC CHF were 66.7 %, reliably high fermentation indices were noted. At the same time, level of ALT was 39 % (p<0.01) and 35 % (p<0.001) higher in comparison with patients without kidney function impairment.
Conclusions. In CHF patients subclinical renal dysfunction has been observed in process of progression of the disease which is characterized by reduction of GFR, increase of residual nitrogen level and fermentation. Urinary enzyme level determination in patients with CHF can be considered as a diagnostic approach for early diagnosis of renal dysfunction.
