Objective To observe the levels of platelet alpha-granule membrane glycoprotein 140 (GMP-140) and fibrinopeptide a (FPA) in patients with acute coronary syndromes (ACS).

Abstract Dynamic changes of serum fibrinopeptide a (FPA) were studied in 12 patients with acute myocardial infarction (ami) and 25 ones with unstable angina (UA).

Methods Prothrombin fragments 1 and 2 (F1+2), fibrinopeptide A (FPA), soluble fibrin monomer complex(SFMC) were examined by enzyme linked immunoassay(ELISA);
