Abstract:
Objective To study the relationship between severity of coronary artery lesion and serum level of apolipoprotein A5 (ApoA5). Methods The level of serum total cholesterol (TC), triglyceride (TG), high-den-sity lipoprotein cholesterol (HDL-C ), low density lipoprotein cholesterol (LDL-C ), apolipoprotein A1 ( APOA1), apolipoprotein B (APOB) ,Lipoprotein(a) and uric acid(UA) were examined in 114 patients with coronary heart disease(CHD) and 40 healthy control subjects;Enzyme-linked immunosorbent assay (ELISA) methods was used to determine APOA5. The eoronay heart disease patients were divided into tree groups by the severity of coronary artery lesion: that is one, two and three vessel lesion. Results Compared with control group, APOA5, ApoA1, HDL-C lev-el of CHD groups were lower(P <0.01 or P<0.05) ,TG ,LP(a)and UA were higher(P <0.01 or P <0.05) ,the difference of TC, LDL-C and APOB were not significant (P>0.05 ). In the subgroups of CHD patients, The serum APOA5 concentrations were signficant different between the CHD patients and control group( F=18.605 ,P<0.01 ). Along with the severity of coronary artery,the level of ApoA5 concentrations had a lower trend. The level of ApoA5 was negatively correlated with serum TG level ( r=-0.208, P=0.040) and LP (a) ( r=-0.088, P <0.001). The level of APOA5 had a positive correlation with the serum HDL-C (r= 0.241, P = 0.016). Conclusion There is negative correlation between severity of coronary artery lesion and serum level of ApoA5. The decrease of ApoA5 maybe a risk factor.
