Effection of serum bilirubin and serum lipid on coronary heart disease

Abstract

Objective To investigate the effection of serum bilirubin and serum lipid on coronary heart disease (CHD). Methods Seventy -five patients with CHD group were divided into hyperlipidemia group(46 cases) and non- hyperlipidemia group (29 cases),35 healthy controls (healthy control group)were enrolled in the study. Serum total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL)serum triglycride ( TG), total cholestrol ( TC ), low density lipoprotein (LDL), high density lipoprotein (HDLand serum lipid were examined for all subiects,and then the results were compared and analyzed. Results The contents of serum TBIL, direct bilirubin (DBIL), indirect bilirubin (IBIL)were lower in hyperlipidemia group than those of non - hyperlipidemia and healthy control group, the difference was significant (P ＜0. 05 ). The contents of serum bilirubin were lower in non - hyperlipidemia group than those of healthy control group, the difference was significant( P ＜ 0.05 ). TC,TG and LDL were higher and HDL was lower in hyperlipidemia group than those of healthy control group and non - hyperlipidemia group, the difference was significant( P ＜0.05). TC,TG and LDL were higher and HDL was lower in non -hyperlipidemia group than those of healthy control group,There was no difference in the two groups( P ＞0.05). Conclusions The lower serum bilirubin level is an independent risk factor of coronary heart disease in hyperlipidemia and non- hyperlipidemia groups.
