A recent study suggested that statin therapy may prevent contrast-induced nephropathy (CIN) following primary angioplasty. Our aim was to assess the effect of statins in this setting in a larger population. We evaluated 589 consecutive patients with acute myocardial infarction who underwent primary angioplasty at our institution. Contrast-induced nephropathy was defined as an increase in serum creatinine by > or =0.5 mg/dL within 72 h following the procedure. Overall, 69 patients (11.9%) developed CIN. The incidence of CIN in the group on statins was 15.9%, as compared with 10.8% in the group not taking statins (p=0.2). Thus, we did not observe a protective effect of statin therapy on CIN development after primary angioplasty.
