Soluble adhesion molecules and marine n-3 fatty acids in patients referred for coronary angiography.Eschen O, Christensen JH, Toft E, Schmidt EB Center for Cardiovascular Research, Department of Cardiology, Aalborg Sygehus, Aarhus University Hospital, Aalborg, Denmark. oe@dadlnet.dk OBJECTIVE: To investigate the relationship between soluble cellular adhesion molecules (sCAMs) and the extent of coronary artery disease (CAD) in patients with stable angina pectoris. METHODS AND RESULTS: Two hundred and ninety-one subjects had fasting levels of circulating intercellular adhesion molecule-1(sICAM-1), vascular cellular adhesion molecule-1 (sVCAM-1), sP-selectin and contents of n-3 polyunsaturated fatty acids (n-3 PUFA) in granulocyte membranes and adipose tissue determined before undergoing elective coronary angiography. Levels of soluble VCAM-1 (983+/-216 versus 893+/-196 ng/l, p<0.001), ICAM-1 (318+/-140 versus 290+/-75 ng/l, p<0.05) and P-selectin (90+/-27 versus 80+/-23 ng/l, p<0.01) were significantly increased in subjects with significant CAD compared to subjects with no significant stenoses. In a linear regression analysis, both sVCAM-1 and sP-selectin, but not sICAM-1, correlated to the presence and the severity of CAD. Both sICAM-1 and sP-selectin were significantly correlated to current smoking status and a history of myocardial infarction. The content of total n-3 PUFA and docosahexaenoic acid in adipose tissue was marginally, but significant positively correlated to VCAM-1. CONCLUSION: sVCAM-1 and sP-selectin may serve as markers of CAD in patients with stable angina pectoris. Only sVCAM-1 was weakly correlated to n-3 PUFA in adipose tissue.
