Soluble tumorigenicity suppression protein (sST2) as a possible biomarker in patients with acute coronary syndrome

Many prognostic tools have been developed over the past decades, however, the identification of biomarkers that can predict the risk of acute coronary disease and its associated complications, especially heart failure, remains a promising direction, the study of which will provide understanding of the pathophysiology of this disease and identify new targets for therapy. One such potential biomarker is soluble suppression of tumorigenicity 2, which is able not only to predict left ventricular remodeling and poor clinical outcome among patients with acute coronary syndrome, but also to complement other well-established cardiac biomarkers such as natriuretic peptides and cardiac troponins. At the same time, if a number of separate but often converging pathways are involved in the pathogenesis of acute coronary disease, then multimarker approaches with various combinations of new cardiac biomarkers and their continuous assessment are likely to improve the prediction of cardiac risk and long-term outcomes.
