[The effect of ionic and nonionic contrast media (amidotrizoate, iopromide) on cardiac function (contractility,
Insights
Non-ionic contrast media like Iopromide minimally impact heart function compared to ionic agents such as Amidotrizoate. This study found ionic contrast agents negatively affected contractility, making non-ionic options safer for critical patients.
Area of Science:
- Cardiology
- Radiology
- Pharmacology
Background:
- Contrast agents are crucial for medical imaging.
- Ionic contrast agents have been associated with cardiac side effects.
- Evaluating the cardiac safety of different contrast agent types is essential.
Purpose of the Study:
- To compare the cardiac effects of ionic (Amidotrizoate) and non-ionic (Iopromide) contrast agents.
- To assess the influence on heart contractility, relaxation, perfusion, and extrasystoles.
- To determine the suitability of contrast agents for critically ill patients.
Main Methods:
- Investigated the influence of Amidotrizoate and Iopromide on cardiac parameters in 30 patients.
- Monitored heart contractility, relaxation, perfusion, and extrasystole rate.
- Compared the effects of ionic versus non-ionic contrast media.
Main Results:
- Iopromide (non-ionic) resulted in significantly less cardiac influence compared to Amidotrizoate (ionic).
- A negative inotropic effect was observed exclusively with Amidotrizoate.
- Heart relaxation and perfusion were also less affected by Iopromide.
Conclusions:
- Non-ionic contrast media, specifically Iopromide, demonstrate superior cardiac safety.
- Ionic contrast agents like Amidotrizoate pose a greater risk, particularly a negative inotropic action.
- Non-ionic contrast agents are recommended for use in critical patients due to their reduced impact on cardiac function.
Abstract:
In 30 patients the influence of ionic (Amidotrizoate) and non-ionic (Iopromide) contrast agents on the heart parameters contractility, relaxation, perfusion and the rate of extrasystoles was investigated. They were significantly less influenced by Iopromide than by Amidotrizoate. A negative inotropic action was detectable only for Amidotrizoate. It is concluded that non-ionic contrast media should be used especially for critical patients.
