The development of renal dysfunction in patient with acute myocardial infarction, especially in those who underwent angiography, is an actual problem, because it worsens the prognosis for those patients. In order to diagnose this condition in time the search for biomarkers is going. One of them is the Growth differentiation factor 15 (GDF 15). Purpose: estimate the role of various markers in the development of cardiorenal syndrome in patients with acute coronary syndrome (ACS). Methods: 73 patients were screened with different forms of ACS (55 male and 18 female), mean age was 61, 8 ± 1, 3 years. In anamnesis patients had: 23% - previous myocardial infarction, 51% - stable angina, 84% - hypertension, 16% - diabetes mellitus, 6 % - chronic kidney disease. Based on the results of the examination glomerular filtration rate (GFR) was calculated by Modified diet renal disease method (MDRD). A group of patients has been selected (n = 54), their creatinine level was determined during the first 24 hours and after 48 hours. All patients were divided into two groups according to acute kidney injury network classification (AKIN): 21 patient in the first group with negative dynamic (1st stage AKIN and higher), 33 patient in the second group without creatinine dynamic. In addition, the levels of GDF 15, N terminal-pro B-type natriuretic peptide (NT-pro BNP) were determined during the first day of hospitalization (normal range of GDF 15 <1200 pg / ml, NT pro-BNP <200 ng/ml). The follow-up period was 6 months. Results: By comparing selected groups significant difference was found in creatinine level and GFR in both groups ( < 0.001;  < 0.01, respectively). The analyses of biomarkers interconnection (NT pro-BNP, GDF 15) and GFR showed significant difference of estimated parameters in both groups as well ( ≤ 0.04; ≤ 0.02, respectively). Also, correlation of high and medium strength was found between biomarkers (GDF 15, NT pro-BNP) and GFR ( ≤ 0.0001, p≤0.01). Conclusions: The biomarker GDF 15 can be used for risk stratification in development of acute kidney injury in patients with ACS, its as sensitive as the known marker NT- pro BNP. For high prognostic possibility we can use combination of biomarkers.
