[Hemodynamic effects of non-ionic iomeprol 350 and ionic diatrizoate 370 during levocardiography and coronary angiography--double-blind randomized comparison of 2 contrast media].
A double-blind randomized study was performed in 49 patients to compare the hemodynamic changes induced by two contrast agents: non-ionic low osmolar lomeprol 350 (IO, n = 25) and ionic high osmolar Diatrizoat 370 (DIA, n = 24). We observed significant changes in hemodynamic parameters after laevocardiography with DIA: a decrease in LVSP from 125 +/- 14 to 113 +/- 14 mmHg, a decrease in mean aortic pressure from 96 +/- 9 to 84 +/- 10 mmHg and in max dp/dt from 2086 +/- 628 to 1861 +/- 654 mm Hg/sec. LVEDP increased from 13 +/- 5 to 17 +/- 6 mmHg and cardiac output from 5.9 +/- 1.2 to 7.7 +/- 1.2 l/min. Heart-rate also rose slightly, but insignificant. IO did not alter these parameters. After selective coronary angiography both groups did not differ significantly in systolic aortic pressure, but DIA caused a drop in diastolic aortic pressure after 10 to 15 sec and a bradycardia in the first five sec, in contrast to IO. These effects can be explained by a cardiodepressive action of contrast agents on left ventricular function, an increase in circulating volume and a reduced peripheral vessel resistance. Differences between both agents are probably due to their different osmolality. IO is a safe contrast agent, compatible in contrast to DIA. In patients with borderline left-ventricular function, IO is preferable, it exerts only very slight effects on cardiovascular function.
