title: Atorvastatin and prevention of contrast induced nephropathy following coronary angiography.
abstract: BACKGROUND
  Contrast induced nephropathy (CIN) is one of the most common complications after radiographic procedures using intravascular radiocontrast media. The aim of the current study was to assess the effect of atorvastatin on prevention of CIN in patients undergoing coronary angiography.
  
  
  METHODS
  In a clinical trial study, 200 patients referred for angiography were randomly divided into two groups of using 80 mg atorvastatin and placebo before the procedure. Furthermore, 100 patients who were under chronic treatment of statins were included as the third group. Serum creatinine (Scr) levels before and after the procedure were evaluated and incidence of CIN (post-procedural Scr of >0.5 mg/dl or >25% from baseline) was assessed.
  
  
  RESULTS
  Mean age of the participants was 60.06 ± 0.69 years and 276 (92%) were male. There were no significant differences between group with respect to age and gender. In pre-operation atorvastatin, placebo and long term statin groups, the incidence of CIN was 1%, 2% and 1%, and mean changes of Glomerular filtration rate (GFR) was 3.68 ± 1.32, -0.77 ± 1.21 and 1.37 ± 0.86; and mean changes of creatinine (Cr) was -0.05 ± 0.02, 0.02 ± 0.02 and -0.01 ± 0.01 respectively. (P = 0.776, 0.026 and 0.041 respectively). In pre-operation atorvastatin group, Cr decreased, and GFR increased significantly (P = 0.019 and 0.007 respectively).
  
  
  CONCLUSIONS
  pre-operation short term high dose atorvastatin use was associated with a significant decrease in serum Cr level and increase in GFR after angiography.
