A New Type of Contrast Medium in Selective Coronary Arteriography

A new contrast medium Ph DZ 59B when used for selective coronary arteriography was found to give significantly fewer electrocardiographic changes than a currently used metrizoate preparation. The preparations were examined at the same iodine concentrations in patients. The findings confirm earlier results from comparative studies in peripheral arteriography, carotid arteriography and angiocardiography that this newly synthesized agent gives less adverse effects than other contrast agents currently used.
