[Adverse effects of a new non-ionic contrast medium in heart catheterization]

Tolerance of a New Non-ionic Contrast Medium during Heart Catheterization The new non-ionic contrast medium iomeprol (CAS 78649-41-9) was investigated for adverse reactions and diagnostic quality in 75 patients undergoing heart catheterization. Blood pressure and ECG were continuously registered. The patients were asked for subjective complaints by using a standardized questionnaire. Experienced cardiologists assessed the diagnostic quality of the angiograms. With iomeprol neither fatal nor severe reactions were observed. The dye had only little influence on diastolic and systolic blood pressure; heart rate was not significantly influenced. Minor and partly moderate adverse reactions all being completely reversible were observed in 14 patients (18.7%). One patient complained of strong heat sensation after dye injection into the left ventricle. The diagnostic quality of the angiograms allowed to make a definitive diagnosis in all cases. Thus, iomeprol proved to be a suitable and safe contrast medium for heart catheterization.
