Risk factors of acute kidney injury in patients with acute myocardial infarction / 中华急诊医学杂志

ABSTRACT

Objective To explore the risk factors for acute kidney injury (AKI)in patients with acute myocardial infarction (AMI).Method The medical data of hospitalized patients with AMI admitted from October 2013 to May 2014 were reviewed.All patients were divided into AKI group and non-AKI group.The univariate comparison analysis were performed to obtain the AKI risk factors.Results A total of 565 patients were enrolled.The incidence of AKI (n =91 )was 16.1% and there were 474 non-AKI patients.The mortality of AKI group was 19.8% and mortality of non-AKI group was 0.4% (P <0.01). Univariate analysis demonstrated that the risk factors of AKI were age,hypertension,previous myocardial infarction,heart failure history,chronic kidney disease,cerebral infarction history,peripheral vascular disease;ventricular fibrillation,heart rate,Killip grade ≥3 stage,left ventricular ejection fraction,serum creatinine,eGFR,hemoglobin,blood urea nitrogen,troponin I,B-type natriuretic peptide and C-reactive protein,fasting glucose,albumin,maximum daily dose of furosemide,non-use of ACEI /ARB and statins, the use of intra-aortic balloon pump, temporary pacemaker and pulmonary mechanical ventilation, implementation of PCI and coronary artery bypass graft surgery.Conclusions These risk factors for AKI after AMI were found to identify high-risk patients,helping the clinicians to make decision for preventive intervention.
