Atherogenic dyslipidemia includes patients who have coronary heart disease (CHD) or CHD risk equivalents, whose TG level is not adequately controlled after statin monotherapy. According to the published ESC/EAS consensus, fibrate is suggested to be added to this type of patient who has insufficient improvement. The purpose of the study is to evaluate the efficacy on lipid control and the safety of adding fenofibrate in patients on a background of statin treatment.
