Aim: To investigate the relationship between serum miRNA-208 and platelet function in patients with acute coronary syndrome( ACS). Methods: A total of 60 cases of ACS( ACS group) and 20 cases of non-ACS( control group)were collected,and the ACS group was further allocated into myocardial infarction group( AMI group,n = 32) and unstable angina pectoris group( UA group,n = 28). Platelet( PLT),platelet distribution width( PDW) and mean platelet volume( MPV) were measured. The serum miRNA-208 was measured by re...
