Overview
The reported incidence varies widely according to the presence or absence of risk factors, and usually associated with a significantly higher risk of in-hospital and 1-year mortality, even in patients who do not need dialysis.
Natural history, Complications and Prognosis
Studies have substantiated greater all-cause and cardiovascular mortality[1], prolonged duration of hospitalization[2], and late cardiovascular events[3] associated with CIN. The evidence is seen mostly in patients undergoing PCI.[4][5] Weisbord et al showed that an absolute increase in serum creatinine of 0.25 to 0.5 mg/dL within 72 hours after coronary angiography was associated with significantly greater odds for in-hospital mortality in the 30 day period following the procedure.[5] The need for dialysis following CIN is also a separate prognostic indicator. Dialysis requirement has been associated with a fivefold increase in all-cause mortality when compared to patients with CIN not requiring renal replacement. Furthermore, mortality in the former group was as high as 81% at 2 years.[6] Several of the studies targeting prognosis following CIN have been limited by the confounding factors mostly because high risk patients for CIN are naturally at higher risk for cardiovascular complications.
