Abstract：Objective To investigate the incidence of hyperkalaemia and analyze the risk factors in pa-tients with acute kidney injury(AKI)in cardiology department.Methods We conducted a retrospective case-con-trol study,using the electronic medical information of the patients in Guangdong General Hospital. Results A to-tal of 37 837 patients were included in this study and 1 571(4.3%)patients with AKI were detected.Hyperkalae-mia occurred in 517 patients(1.4%).The incidence of hyperkalaemia in AKI patients was higher than that in non-AKI patients(10.1% vs. 1.0%,P < 0.001)and the incidences of hyperkalaemia at AKI stage 1~3 were 2.6 %, 13.9% and 20.6 %,respectively. Multiple logistic regression analysis demonstrated that AKI stages,chronic kid-ney disease and heart failure were risk factors for hyperkalaemia.AKI and hyperkalaemia were related to increased hospitalization expenses,delayed hospital stay,renal replacement therapy and in-hospital mortality. Based on AKI,the combination of hyperkalemia could significantly increase clinical burden and adverse outcomes. Conclu-sion In cardiology department,the monitoring of serum creatinine and potassium level should be emphasized.
