OBJECTIVE: To observe the changes in serum soluble intercellular adhesion molecule type-1 (ICAM-1), vascular cell adhesion molecule type-1 (VCAM-1), E-selectin and von Willebrand factor (vWf) in patients with acute coronary syndrome.
METHODS: Serial venous blood samples were taken from 21 patients with acute myocardial infarction (AMI) before and 4, 8, 12, 24, 48 and 72 h after thrombolytic treatment or direct PTCA. One blood sample was drawn from 16 patients with unstable angina and 16 control subjects. Serum concentrations of ICAM-1, VCAM-1, E-selectin and vWf were determined using a double antibody sandwich enzyme-linked immunosorbent assay.
RESULTS: Serum levels of ICAM-1, VCAM-1, E-selectin and vWf were higher in patients with acute coronary syndrome than in controls. Patients with AMI and successful reperfusion therapy had a significant reduction in the serum concentration of ICAM-1 and E-selectin at 24 and 48 h, VCAM-1 at 24 and 72 h and vWf at 12, 24, 48 and 72 h, but had peak in serum levels of ICAM-1 and E-selectin at 4 h. The number of diseased coronary arteries was not related to the levels of ICAM-1, VCAM-1 and E-selecin.
CONCLUSION: The serum concentration of soluble cell adhesion molecules was elevated significantly in patients with acute coronary syndrome. Successful reperfusion therapy was associated with a reduction in the serum concentrations of soluble cell adhesion molecules in patients with AMI.
