Randomized Controlled Trial Comparative Study
Prognostic value of soluble ST2 in the Valsartan Heart Failure Trial.
Soluble ST2 (sST2), a biomarker related to inflammation, is associated with outcomes of patients with heart failure. In-depth analyses of the relationship among sST2, changes in sST2, and patient outcomes are reported. ⋯ In this study, baseline sST2 was nonlinearly associated with patient outcomes but did not provide substantial prognostic information when added to a clinical prediction model that included N-terminal probrain natriuretic peptide. An increase but not decrease in sST2 was independently associated with outcomes. Additional research is needed to determine whether monitoring ST2 levels can improve patient outcomes.
