Comparison of iohexol and ioxaglate in selective coronary angiography.

The hemodynamic effects of two low osmolar contrast media, iohexol and ioxaglate, were compared in 24 patients undergoing selective coronary angiography because of suspected significant coronary heart disease. Neither medium had a significant effect on left ventricular function when injected into the left or right coronary artery. The image quality and radiological value of the media were similar. Mild side effects were suffered by 14 patients but no statistical difference was shown between the media as to the number of adverse reactions.
