    Abstract:
    OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a common complication of diagnostic and therapeutic catheterizations, especially in the setting of acute coronary syndrome (ACS). Fibrinogen is a well-known cardiovascular risk factor. We evaluated whether serum fibrinogen level is associated independently with CI-AKI in patients with ACS who underwent a percutaneous coronary intervention (PCI). METHODS: Patients (n=710, aged 61 ± 13, 69% men) were classified into two groups: CI-AKI and non-CI-AKI. CI-AKI was defined as an increase of at least 0.5 mg/dl or at least 25% in the serum creatinine level within 72 h following PCI. RESULTS: CI-AKI occurred in 75 (10.6%) patients. We found significantly higher serum fibrinogen levels in patients who developed CI-AKI than in those who did not (498 ± 152 vs. 386 ± 96 mg/dl, P<0.001). Multivariate logistic regression analysis showed that serum fibrinogen level (odds ratio 1.006, 95% confidence interval 1.003-1.009, P<0.001), age, glomerular filtration rate, female sex, and white blood cell count were correlated with the development of CI-AKI. CONCLUSION: Serum fibrinogen level is associated independently with a higher risk of CI-AKI in patients with ACS undergoing PCI.
