Aim: We aimed to compare the incidence of contrast-induced nephropathy (CIN) between atorvastatin versus rosuvastatin in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary coronary angioplasty.
Methods: One hundred ninety-two consecutive patients, who underwent primary percutaneous intervention (p-PCI) with the diagnosis of STEMI, were included in the study. The patients were randomized to take atorvastatin 80 mg (n=98) or rosuvastatin 40 mg (n= 94) before the procedure. Biochemical and complete blood count measurements were done at baseline and at 48 hours following admission.
Results: The incidence of CIN was 8.9% (n= 17) in the entire groups. The analysis performed between the statin groups revealed no statistical difference in any of the renal dysfunction indicators [baseline creatinine, baseline estimated glomerular filtration rate (eGFR), creatinine at 48 h, eGFR at 48 h, difference between baseline and 48 h creatinine, the per cent increase in the creatinine at 48 hours relative to basal creatinine]. In STEMI patients undergoing primary PCI, only the amount of the contrast agent administered was determined to be an independent predictor for CIN (OR and 95% CI: 1.08 (1.03- 1.13), P< or = 0.001). Left ventricular ejection fraction exhibited borderline statistical significance (OR and 95% CI: 0.88 (0.77-1.01), P= 0.07).
Conclusion: Atorvastatin and rosuvastatin had similar efficacy in preventing CIN in patients with STEMI undergoing P-PCI.
