Adhesion molecules on the endothelial cell membrane play an important role
in the pathogenesis of atherosclerosis. Levels of soluble forms of cell adh
esion molecules are reportedly elevated in patients with peripheral artery
vessel disease and in patients with an atherosclerotic aorta. The present s
tudy investigated the association of serum levels of soluble vascular cell
adhesion molecule 1 (sVCAM-1), soluble intercellular adhesion molecule 1 (s
ICAM-1), and soluble P-selectin (sP-selectin) with coronary heart disease (
CHD) and the extent of coronary atherosclerosis, and examined the influence
of serum levels of lipids, lipoproteins and apolipoproteins (apo) in subje
cts with (n = 52, M/F: 43/9) and without (controls, n = 40, M/F:25/15) angi
ographically proven coronary atherosclerosis. After controlling for age and
gender, levels of sVCAM-1 (least squares mean +/- std error: 565 +/- 36 ng
/ml vs 540 +/- 41 ng/ml, ns), sICAM-1 (261 +/- 17 ng/ml vs 247 +/- 19 ng/ml
, ns), and sP-selectin (142 +/- 8 ng/ml vs 149+10 ng/ml, ns) in patients wi
th coronary atherosclerosis were not different from those in controls, as a
ssessed by an analysis of covariance. After also adjusting for body mass in
dex, hypertension, diabetes mellitus, and smoking by a multiple logistic fu
nction analysis, the association of sVCAM-1, sICAM-I, and sP-selectin with
CHD was still not significant. Levels of sVCAM-1, sICAM-1, and sP-selectin
were also not related to the extent of coronary atherosclerosis as judged b
y the number of stenosed vessels. However, inverse (p < 0.05) relationships
were observed between sVCAMs and serum levels of HDL3-cholesterol, apo A-I
I, and lipoprotein containing apo A-I and A-II, between sICAMs and levels o
f apo A-II and Lp A-I/A-II (Lp A-I/A-II), and between sP-selectin and lipop
rotein containing only apo A-I. In conclusion, serum levels of soluble VCAM
-1, ICAM-1, and P-selectin were not related to CHD or the extent of coronar
y atherosclerosis, but were inversely related to serum levels of high-densi
ty lipoprotein-related lipoproteins.
