Coronary angiography with Iopamidol.

Iopamidol, a new non-ionic contrast medium with low osmolality, was compared with Isopaque Coronar during selective coronary angiography in 16 patients. Iopamidol caused significantly less bradycardia, less ECG changes and less fall in blood pressure than Isopaque Coronar. No subjective adverse effects such as chest pain, vomiting, nausea or sensation of heat occurred. The results indicate that Iopamidol has advantages as a contrast medium for coronary angiography.
