Lipoprotein Lipids, Apolipoproteins and their Combinational Index in Coronary Artery Disease Assessed by Coronary Angiography

Abstract

The levels of serum lipoproteins and apolipoprotein in 113 peoples undertaking coronary angiography were examined, and their correlation between the severity of coronary stenosis were evaluated. Stenosis score caliculated from angiography were higher in IIb>IIa>IV hyperlipoproteinemia. In type IIa, the stenosis scores were not correlated with each levels of lipoprotein cholesterol, and apo A-I and apo B. But the ratios of LDL-C/apo B, LDL-C/apo A-I and apo B/apo A-I were significantly correlated with stenosis scores. These results suggest that the combination of apo B, apo A-I and LDL-C were useful indicator for forcasting the degree of coronary stenosis.
