Popis: | Changes in contractile function induced by modern roentgen contrast media (CM) were examined in isolated rat hearts. Four coronary perfusions were undertaken in each heart with increasing volumes of each CM in order to test a wider spectrum of potential side-effects. Left ventricular developed pressure (LVDP) and heart rate (HR) were recorded. Six commercially available or investigational CM were examined: A, Hexabrix (ioxaglate 320 mg I/ml, Na 146 mM); B, Iosvist (iotrolan 300 mg I/ml, Na 6 mM);C, Visipaque (iodixanol 320 mg I/ml, Na 19 mM, Ca 0.3 mM); D, "Iodixanol high Ca-Mg" (iodixanol 320 mg I/ml, Na 19 mM, Ca 1.2 mM, Mg 0.6 MM); E, "Iohexol I 350" (iohexol 350 mg I/ml, Na 28 mM); and F, "Iohexol I 150" (iohexol 150 mg I/ml Na 28 mM). A, E and F were low-osmolal (400-940 mosm/kg H2O) CM whereas B, C and D were essentially isosmolal. Contractile changes (transient LVDP depression) was volume-dependent. Maximal values for LVDP depression were "Iohexol I 150" 11-22% |
