Acute kidney injury based on the KDIGO criteria among ST elevation myocardial infarction patients treated by primary percutaneous intervention

Background Acute kidney injury (AKI) following acute ST elevation myocardial infarction (STEMI) is associated with adverse outcomes. The recently proposed KDIGO criteria suggested modifications to the consensus classification system for AKI, namely lowering the threshold of increase in absolute serum creatinine and extending the time frame for AKI detection to 7 days. We evaluated the incidence, risk factors, and long-term mortality associated with AKI as classified by the KDIGO definition in a large single center cohort of consecutive STEMI patients.
