[Soluble ST2 - biomarker for prognosis and monitoring in decompensated heart failure]

The review aims to appraise the value of determining the concentrations of the new biomarker sST2 for assessing prognosis and monitoring treatment effectiveness of patients with decompensated heart failure during an episode of decompensation and during long-term follow-up after discharge from the hospital. The article analyses in detail the expedience of sST2 measurement in a patient with ADHF on admission and discharge from the hospital and the changes in the biomarker level during the period of active treatment for risk-stratification in patients, presents the optimal threshold values of sST2, which should be oriented when selecting patients with high and very high risk. The importance of subsequent monitoring of the marker concentration during long-term observation in emphasized to predict the risk of death, HF re-decompensation / HF rehospitalization. The potential benefits of choosing sST2 as the optimal marker for serial measurement during long-term follow-up, as well as evaluating the treatment effectiveness in patients with HF, compared to the "classical" variant - natriuretic peptides are shown.
