NPPB and myocardial infarction: Recent observations suggest an important prognostic value of sST2, either in chronic heart failure, where it predicts patients outcome beyond N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponin T [10], or in acute heart failure [11], where it is useful for monitoring and driving therapeutic decisions in patients with acutely decompensated heart failure (ADHF) and acute myocardial infarction (AMI) [12].
