A Study on Relation Between Various lipid lipoprotein and Bilirubin Combinations and Coronary Heart Disease

Objective To study the relation between composite index of serum bilirubin and serum lipid variables and coronary heart disease. Methods A total of 80 patients who had undergone coronary angiography entered the study. They were dividied into two groups by their results of coronary angiography:1.CHD 2.Normal. We tested serum bilirubin(TBIL),cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),TC/(HDL-C+bilirubin),LDL-C/(HDL-C+bilirubin). Their relation were investigated. Results Serum bilirubin of CHD group is lower than normal group,Cholesterol(TC),low density lipoprotein cholesterol(LDL-C),TC/(HDL-C+bilirubin),LDL-C/(HDL-C+bilirubin) of CHD group is higher than normal group (P 0.05). Each of these bilirubin-containing ratio is risk factor of CHD. Conclusion We think over various lipid lipoprotein and TC/(HDL-C+bilirubin) ratio, LDL-C/(HDL-C+bilirubin) ratio together will improve the diagnosis of CHD.
