Coronary angiography with iohexol and other contrast media in the dog. III. Contractility of the left ventricle.

Compared with the ionic contrast medium diatrizoate the new non-ionic media iohexol and 711 produced significantly less reduction of contractile force, left ventricular pressure and the first derivative of left ventricular pressure during left coronary angiography in the dog. These two media may be expected to have similar effects on the function of the myocardium as metrizamide.
