Comparison of atorvastatin and rosuvastatin on preventing contrast-induced-nephropathy in patients undergoing primary percutaneous coronary intervention: A multi-centric randomized triple-blind clinical trial

Abstract

Background: Patients with Contrast-Induced-Nephropathy (CIN) are at a greater risk of in-hospital complications, longer hospitalization, and long-term mortality in comparison with those without CIN. Despite many studies on the helpful effects of statins in preventing contrast-nephropathy, there is not enough evidence comparing different statins in inhibiting CIN. So, we planned this study to compare the efficacy of rosuvastatin and atorvastatin in prevention of contrast-induced nephropathy. Methods: This was a randomized clinical trial. The efficacy of two known statins, atorvastatin and rosuvastatin were compared in prevention of CIN in patients with ST-Elevation Myocardial Infarction (STEMI) who underwent Primary Percutaneous Intervention (PPCI) between May 2015 and April 2016 in Qaem and Imam Reza hospital, Mashhad, Iran. Subjects were divided randomly to 80-mg atorvastatin or 40-mg rosuvastatin group before PPCI. Participants’ characteristics including echocardiographic, laboratory and demographic data were recorded and incidence of CIN was assessed. Results: Two hundred cases with STEMI undergoing PPCI were recruited in the study and randomized to 80-mg atorvastatin (n = 98) or 40-mg rosuvastatin (n = 102) group before PPCI. The incidence of CIN was 5.67% (n = 13) in all participants; 6.3% (n = 7) in the rosuvastatin group and 5.1% (n = 6) in the atorvastatin group. There was a significant difference between creatinine and Glomerular Filtration Rate (GFR) after 48 hours of PPCI. Creatinine was lower and GFR was higher in the rosuvastatin group (P = 0.029, P = 0.005). Conclusion: There was a little trend for prevention of CIN in patients after PPCI in rosuvastatin group compared to atorvastatin group, in full dose. However, this preference was not clinically relevant.
