Chinese Journal of Interventional Cardiology 1993;0(02):-
Objective To investigate the correlation between abnormal lipid metabolism and coronary artery lesions. Methods Two hundred and sixty seven patients were devided into the control group ( n =101) and the coronary heart disease (CHD) group ( n =166), which included single vessel lesion ( n =54), double vessel lesions ( n =68) and triple vessel lesions ( n =44) according to coronary angiography. At the same time the lipid components were examined and the ralationship between serum lipid level and coronary artery lesions were analysed. Results Compared with the control, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) level were significantly elevated while but high density lipoprotein cholesterol (HDL-C) was lowered in the CHD group. The severity of coronary lesions was increased with the elevation of TC, LDL-C, apolipoproteinB (ApoB), TC/HDL-C, LDL-C/HDL-C, and the reduction of HDL-C. There were significant differences in terms of lipid level beteewn the CHD group and the control. The analysis showed that TC/HDL-C and LDL-C/HDL-C were most directly correlated with the coronary artery lesions in the CHD group. Conclusion The results suggest that the severity of coronary artery lesions correlated with abnormal lipid metabolism, and LDL-C/HDL-C, TC/HDL-C are better indicators than other lipid components.
