Moreover, only about one-third of those treated with hyperlipidemia achieve their target LDL-C goal . Tremendous efforts have been taken to the management of hyperlipidemia. The National Cholesterol Education Program (NCEP) Expert Panel in US [6-8] or Japan Atherosclerosis society in Japan [9, 10] has historically provided consensus recommendations on the evaluation and treatment of hyperlipidemia.
