To the Editor: Contrast induced nephropathy (CIN) is one of the most important and frequent complications of invasive coronary procedures.1 We have previously reported a multicentre randomised trial comparing use of iso-osmolar and low osmolar contrast agents (iopromide and iodixanol, respectively) in patients with pre-existing renal impairment.2 The overall proportion of patients developing CIN by Day 7 was around 25%, and there was no statistical difference between the different contrast media.
