OBJECTIVE: Type 1 cardiorenal syndrome (CRS) is an acute renal failure in patients with acute decompensated heart failure with an incidence of 24% to 45%. The aim of our study was to investigate the significance of new renal biomarkers to predict type 1 CRS.

PATIENTS AND METHODS: The study included 111 patients with acute decompensated heart failure diagnosed at the Istanbul Medical Faculty Emergency Department between 2014 and 2016, and 24 healthy volunteers. All urine samples were stored at -80°C after centrifugation. Samples were run according to the instructions of TIMP-2, ILGF-7, KIM-1, and IGFBP-7 ELISA kits. Diuretic treatments were then administered with intravenous administration of at least 80 mg furosemide per day. Follow-up biochemical and spot urine specimens were taken after 72 hours. For statistical analysis, SPSS version 21.0 statistical software was used. Significance was evaluated at p<0.05.

RESULTS: The baseline creatinine level was measured as 1.33 ± 0.39 mg/dL in the heart failure group. It was seen that 67% (75) of the patients had increased creatinine levels and developed type 1 CRS. ILGF-7, TIMP-2, and (ILGF-7 * TIMP-2) values were significantly higher in patients with cardiorenal syndrome when we separated the two groups as patients with and without cardiorenal syndrome (0.40 (0.25-0.71), p1: 0.049/2.40 (1.42-3.70), p2: 0.003/1.15 (0.29-2.43), p3: 0.001).

CONCLUSIONS: Renal tubular markers reveal promising developments in the pathophysiology of cardiorenal syndrome in light of recently obtained data. Renal tubular biomarkers may have the potential to be a predictor of heart failure and cardiorenal syndrome.
