INTRODUCTION: Contrast-induced nephropathy (CIN) is acute kidney injury (AKI), caused by administration of iodinated contrast media. The reported risk factors of CIN are: pre-existing renal dysfunction, admission anemia, diabetic nephropathy, old age, dehydration, high volume and osmolarity of administered contrast media. Patients with acute myocardial infarction (AMI) have threefold higher risk of developing CIN. The aim of the study was to identify risk factors of CIN among patients who underwent percutaneous coronary intervention (PCI) due to AMI.
METHODS: This retrospective single-centre study included 257 patients (mean age, 69.19 ± 1.4 years; men 66.15%) undergoing PCI for AMI between January 2012 and January 2013. Demographic data, type and location of MI, co-morbidities and laboratory results were analysed.
RESULTS: CIN was found in 50 out of 257 patients (19.5%). Patients who developed CIN were older (p = 0.001), more commonly had chronic kidney disease (p = 0.01) and lower LVEF (p = 0.01). Baseline Red Cell Distribution Width (RDW) was significantly higher in the CIN group (14.85 ± 4.6 vs. 13.62 ± 1.3, p = 0.001). CK-MB levels on admission were significantly higher in the CIN group compared to the non- CIN group (95.6 ± 129.9 vs. 47.03 ± 61.3, p = 0.001). Multivariate model including "classical" CIN risk actors revealed that only baseline CK-MB level (p = 0.001), age >75 years (p = 0.001) and baseline RDW (p = 0.03) were independent predictors for the development of CIN.
CONCLUSION: In conclusion, increased CK-MB on admission as a surrogate of time of ischemia, and increased RDW levels on admission as a marker of chronic in ammation are independently associated with higher risk of CIN among patients treated with primary PCI.
