The diagnostic role of signal peptide-C1r/C1s, Uegf, and Bmp1-epidermal growth factor domain-containing protein 1 in non-ST-elevation acute coronary syndrome

Abstract

Objective: Chest pain and/or electrocardiogram changes in non-ST elevation or suspicious chest pain and cardiac marker elevations are defined as non-ST-elevation acute coronary syndrome (NSTE-ACS). Serial electrocardiogram and marker follow-up are needed to make a diagnosis of NSTE-ACS and to eliminate noncoronary chest pain (NCCP). Signal peptide-C1r/C1s, Uegf, and Bmp1-epidermal growth factor domain-containing protein 1 (SCUBE1) is stored within the a granules of inactive platelets and secreted at a high rate during thrombosis. We believe that SCUBE1 may be a sensitive early diagnostic indicator in distinguishing coronary-induced chest pain from noncoronary-induced chest pain.
