- Abstract
<bold>Background: </bold>Age is a major predictor of contrast-induced acute kidney injury (CI-AKI). Few studies have focused on CI-AKI in elderly patients with acute coronary syndrome (ACS).<bold>Methods: </bold>We compare the incidence of CI-AKI in patients <75 and ≥75 years enrolled in the Protective effect of Rosuvastatin and Antiplatelet Therapy On contrast-induced acute kidney injury and myocardial damage in patients with ACS (PRATO-ACS) study and explore the impact of high-dose rosuvastatin on CI-AKI and clinical outcomes in the 2 age-groups. Statin-naive patients with non-ST-segment elevation ACS scheduled for early invasive strategy (total 504) were randomized to rosuvastatin (40 mg on admission followed by 20 mg/day) or no statin treatment. Contrast-induced acute kidney injury was defined as creatinine increase ≥0.5 mg/dL or ≥25% above baseline within 72 hours after contrast administration. All patients were stratified in tertiles according to baseline high-sensitivity C-reactive protein (hs-CRP).<bold>Results: </bold>Rate of CI-AKI was significantly higher in patients ≥75 years (15.9% vs 8.7%, odds ratio: 2.001; 95% confidence interval: 1.14-3.53, P = .015). No significant interaction was observed between age and statin treatment (P = .17). Pretreatment with rosuvastatin was associated with 65% relative reduction in CI-AKI rate (22/170 [12.9%] vs 8/177 [4.5%], P = .007) in younger patients and 38% (16/82 [19.5%] vs 9/75 [12%], P = .20) in the elderly individuals. The greatest protective effect of statin treatment was achieved in patients with the highest hs-CRP values in both age-groups.<bold>Conclusion: </bold>Patients ≥75 years with ACS had a higher risk of developing CI-AKI. Early high-dose rosuvastatin is efficacious in reducing kidney injury in all patients, especially those with the highest baseline hs-CRP values.
