Efficacy of short-term high-dose atorvastatin for prevention of contrast-induced nephropathy in patients undergoing coronary angiography.

Contrast-induced nephropathy (CIN) is associated with increased morbidity, extended hospital stay, and higher costs. We compared an atorvastatin plus N-acetylcysteine (NAC) regimen with NAC alone in patients undergoing coronary angiography. A total of 130 patients (mean age 54 +/- 10; 77 men) undergoing coronary angiography were studied. Seven CIN cases occurred in the NAC group and 2 in the atorvastatin + NAC group; this difference was not significant. Baseline mean creatinine and estimated glomerular filtration rate (eGFR) were similar between the 2 groups, whereas after the procedure there was a significant creatinine decrease and eGFR increase in the atorvastatin + NAC group. Change in creatinine (baseline creatinine-creatinine after the procedure) was also significantly higher in patients taking statin plus NAC. Atorvastatin may be effective in protecting patients undergoing coronary angiography from CIN.
