摘要
Recently, osteopontin (OPN) mRNA was reported to be highly expressed in atherosclerotic plaques, most strikingly in calcified plaques. We examined if plasma OPN levels are associated with coronary stenosis and calcification in patients with coronary artery disease (CAD). We measured plasma OPN levels in 178 patients undergoing coronary angiography. Compared with 71 patients without CAD, 107 with CAD had higher OPN levels (616 +/- 308 ng/mI versus 443 +/- 237 ng/ml, P < 0.001). A stepwise increase in OPN levels was found depending on the number of >50% stenotic coronary vessels: 540 +/- 293 ng/ml in I-vessel, 615 +/- 230 ng/ml in 2-vessel, and 758 +/- 416 ng/mI in 3-vessel disease. OPN levels also correlated with the numbers of >50% and >25% stenotic segments (r = 0.35 and 0.43, respectively, P < 0.001). In multivariate analysis, OPN levels were significantly associated with CAD (odds ratio = 1.21, 95% CI = 1.05-1.39 for a 100 ng/ml increase) independent of traditional risk factors. Coronary calcification was found in 86 patients. OPN levels were higher in patients with calcification than in those without calcification (608 +/- 328 ng/ml versus 490 +/- 246 ng/ml, P < 0.0 1) and correlated with the number of calcified segment (r = 0.26, P < 0.001). However, OPN levels were not independently associated with coronary calcification. Thus, plasma OPN levels were found to be associated with the presence and extent of CAD.
