**4.13 Acute myocardial infarction**

A study by Rihal and his colleagues pointed that acute myocardial infarction occurring within 24 h before administration of the CM is a risk predictor to CIN (OR = 1.85, p = 0.0006). This study showed that CIN represents a frequent complication in acute myocardial infarction. This can occur, as well, in patients with a normal baseline renal function [30]. In 2082 percutaneous interventions for acute myocardial infarction, a more than sevenfold (3.2 vs 23.3%) elevation in 1-year mortality in patients who acquired CIN was acknowledged [37].
