Abstract
A monoclonal antibody specific for alpha-granule membrane protein (GMP-140) of platelets was used to evaluate the platelet activation degree in 16 cases with acute myocardial infarction (AMI) and 14 cases with unstable angina (UA). The number of GMP-140 molecules on platelet surface reached the highest 48 hours after AMI attack and returned to baseline at the seventh day. The concentration of GMP-140 in plasma began to increase at the first day and decreased to normal at the tenth day. The degree of platelet activation in patients with UA is less than that of AMI.
