To compare intercellular adhesion molecule-@ ( ICAM-@ ) and vascular cell adhesion molecule-@ ( VCAM-@ ) serum levels between patients with stable ( SAP ) and unstable angina pectoris ( USAP ) undergoing coronary angiography ( CAG ) , investigate effects of CAG on ICAM-@ , VCAM-@ levels in SAP , USAP patients ; probable different effects of non-ionic radiocontrast media ( RCM ) , iso-osmotic iodixanol and low osmolar iopamidol , on these adhesion molecules ( AM ) .
