This study shows an increase in von Willebrand factor antigen in blood collected from the coronary sinus shortly after coronary angiography with an ionic contrast agent (diatrizoate), but not a nonionic contrast agent (iohexol). These findings suggest that ionic contrast agents may cause more endothelial injury than nonionic contrast agents.
