Proteomic analysis of adverse outcomes in patients with acute coronary syndromes

► The SELDI-TOF MS was firstly used to predict outcomes in patients with ACS. ► A 4174.39 m/z protein was associated with long-term outcomes in ACS. ► CK-MB and troponin T were only associated with short-term outcomes. ► The 4174.39 m/z protein provides additional prognostic value in ACS. ► The 4174.39 m/z protein may correspond to a member of the CXC chemokine family.
