Contrast-induced nephropathy

The use of coronary angiography as a diagnostic tool in modern hospital medicine continues to rise. With the increasing use of therapeutic coronary interventions, and the increases in procedure times and volumes of contrast media, incidence rates of contrast-induced nephropathy (CIN) have also been seen to climb over recent years. CIN has subsequently been shown to be a significant contributor to morbidity and mortality during hospitalisation. In this current clinical setting, it is incumbent on the modern cardiologist to be aware of this potentially serious complication of angiography, to be familiar with its presentation and treatment, and to be able to recognise at-risk groups and institute prophylactic measures where appropriate.
