[The effect of ionic and nonionic contrast media (amidotrizoate, iopromide) on cardiac function (contractility, relaxation, perfusion)].

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.
