Aim: To investigate the effect of apolipoprotein E (APOE), cholesteryl ester transfer protein (CETP) and proprotein convertase subtilisin kexin type 9 (PCSK9) polymorphisms on the lipid-lowering response to simvastatin therapy in Thai hypercholesterolemic patients.
Method: Two hundred and twenty-five hypercholesterolemic patients in southern Thailand were enrolled and treated with simvastatin 20 or 40 mg per day for 3 months. Serum lipids were measured before and after the therapy.
