Introduction: Cardiovascular diseases are highly prevalent in chronic renal failure patients, especially in diabetic population. Cardiac biomarkers such as pro-brain natriuretic peptide N-terminal piece (NT-proBNP), cardiac troponinT (cTnT) and high sensitive CRP (hsCRP) are increasingly used for early detection. Aims: The authors analysed, which factors influence cardiac biomarker levels in hemodialysed patients and whether these factors depend on the presence of diabetes. Methods: In 28 diabetic and 40 non-diabetic patients on chronic hemodialysis was analysed the association between routine laboratory data, bioimpedance parameters, results of echocardiography and ambulanter blood pressure monitoring on cardiac biomarkers. Multivariation linear regression analysis (ANOVA) was applied for statistical evaluation. Results: The authors found stronger correlation (p = 0,034 vs. p = 0,001) between NT-proBNP and extracellular volumen/total water volumen hyperhydration ratio (ccv/twv) evaluated in diabetics than in non-diabetics. In case of cTnT weren't found any relation with CaxP, iPTH, Kt/V, β2-microglobulin, and serum uric acid levels. The hsCRP was correlated with total cholesterol (p = 0,039) and EPO-dose (p = 0,03) in diabetics, while with serum fibrinogen (p = 0,025) in non-diabetics. The HbA1c didn't influence biomarkers in diabetic group. Conclusions: The factors having an impact on cardiac biomarker levels are similar in diabetic and non-diabetic hemodialysed patients. According to results the presence of end-stage renal disease in a cross-sectional survey probably overcomes the impact of diabetes and quality of glycaemic control on cardiac biomarker levels.
