Аpplication of myocardial damage and heart failure biomarkers in preventive and early diagnosis of aki in acute coronary syndrome

INTRODUCTION . From 15 to 35% of cases of acute coronary syndrome (ACS) are complicated by the development of acute kidney injury (AKI), prevention and early intervention remain the most effective strategy for managing patients with AKI in ACS. THE AIM: This study aimed to explore a risk factors and biomarkers for predictive and early diagnostic of AKI in ACS. PATIENTS AND METHODS . The study included patients hospitalized with a diagnosis of ACS in Pavlov First Saint Petersburg State Medical University. In case of exclusion of ACS, patients were determined in the comparison group, in case of confirmation of the diagnosis of ACS – in the study group. Biomaterial (blood) was taken at admission (T1), 1 day after admission (T2) and 2 days after admission (T3). For the diagnosis of AKI, KDIGO 2012 criteria were used. The measured biomarkers at each point were sST2, troponin I, NTproBNP. RESULTS . The study included 132 patients, the diagnosis of ACS was confirmed in 91 patients and AKI development was in 30 patients, all from the ACS group. The most significant for predictive diagnosis was the assessment of GRACE score> 133 points (AUC=0.760, p=0.001), sST2 level> 27.2 ng / ml (AUC=0.737, p=0.001), Mehran score> 5 (AUC=0.916, p=0.001), modification of the Mehran score (adding 2 points if the patient has sST2> 27.2) increases the predictive ability of AKI, Mehran+sST2> 7 points – AUC=0.928, p=0.001. CONCLUSIONS . The use of a combination of clinical data (hemodynamic parameters, presence of heart failure, routine laboratory data, presence of AKI risk factors) and assessment of biomarkers level, in particular the sST2 level, seems to be an effective method for predictive diagnosis of AKI and requires further research.
