Objective To investigate the relationship between the polymorphism of apolipoprotein E (ApoE) and heart blood-stasis syndrome of coronary heart disease (CHD) or the indexes of blood lipid. Method The types of ApoE (E2/E3, E2/E4, E3/E3, E3/E4, E4/E4), alleles (ε2, ε3, ε4) and indexes of blood lipid ( TC, TG, HDL-C, LDL-C ) were detected and analyzed in the group of heart blood-stasis syndrome of CHD (group 1, n = 112), CHD group (group 2, n = 108 ), group of heart blood-stasis syndrome ( group 3, n = 110) and healthy control g...
