    Abstract:
    BACKGROUND: Role of statins in prevention of contrast-induced acute kidney injury (CI-AKI) in patients undergoing coronary angiography remains controversial. We studied the use of statins in decreasing CI-AKI following coronary angiography. METHODS: We reviewed all patients who underwent coronary angiography with or without PCI and had a follow-up creatinine from January 2012 to December 2016 at a single tertiary care center in the United States. CI-AKI was defined as 0.3 mg/dL absolute rise in creatinine. Patients who were on moderate to high-intensity statins or received moderate to high-intensity statins prior to coronary angiography were included in the statin group. Crude and adjusted odds ratios (AOR) were calculated using univariate multiple logistic regression analysis. RESULTS: Out of 2055 patients (females = 30.7%, mean age 58.0 ± 12.5 years, statin group = 886, non-statin group = 1169), 293 (14.3%) developed CI-AKI. Mean estimated glomerular filtration rate (eGFR) was not significantly different between the statin and the non-statin group (86.5 mL/min/1.73 m2 vs 87.1 mL/min/1.73 m2, p = 0.65). There was no significant difference in the incidence of CI-AKI between statin and non-statin group (14.4% vs 14.1%, p = 0.83). When adjusted for other risk factors, statin use was not significantly associated with decreased risk of CI-AKI (AOR) = 0.8, [95% confidence interval (CI) = 0.6-1.1, p = 0.19]. Results remained statistically non-significant on subgroup analysis of patients with acute coronary syndrome (ACS) (OR = 0.8, 95% CI = 0.6-1.2, p = 0.27), patients who had percutaneous coronary intervention (PCI) (OR = 1.1, 95% CI = 0.6-1.7, p = 0.81) and patients with eGFR < 60 mL/min/1.73 m2 (OR = 0.9, 95% CI = 0.6-1.5, p = 0.9). CONCLUSION: Statin use prior to coronary angiography is not associated with decreased incidence of CI-AKI.
