Abstract: | OBJECTIVE: To evaluate the relationship between the serum concentration of TNFalphaRII and some adhesion molecules (including ICAM-1, VCAM-1, P-selectin and E-selectin) and coronary artery stenosis. DESIGN AND SETTING: Observational (cross-sectional) study in a university heart hospital in Tehran, Iran. PATIENTS: 81 patients with angiographically proven coronary artery disease were compared with 75 individuals who had undergone coronary angiography with no significant evidence of stenosis (control subjects). METHODS: Soluble adhesion molecules and TNFalphaRII were determined by enzyme-linked immunosorbent assay technique. sICAM-1 and sP-selectin values were significantly higher in patients with coronary artery disease than in control subjects (146 +/- 38 vs. 132 +/- 48 p < 0.04 and 275 +/- 107 vs. 241 +/- 104 ng/ml p < 0.04 respectively). Multiple logistic regression analysis showed sICAM-1 as an independent discriminating risk factor for coronary artery disease (p < 0.03). Prediction models that incorporated sICAM-1 in addition to other established coronary risk factors were significantly better at predicting risk than the models based on the other risk factors alone. Multiple regression analysis indicated that sP-selectin levels were greater in patients with single-vessel disease than in the respective normal (p < 0.01). CONCLUSIONS: Our findings suggest that sICAM-1 has an association with stable coronary artery disease and the evaluation of this marker may improve the coronary risk assessment in Iranian patients. |
