ABSTRACT
ObjectiveTo investigate the risk factors for acute renal injury (AKI) in patients with ischemic stroke.MethodsPatients with ischemic stroke were enrolled retrospectively.The general clinical data, vascular risk factors, drug use, stroke etiological typing, stroke severity, and baseline biochemical indices were collected.They were divided into either an AKI group or a control group according to whether AKI occurred or not.Multivariable logistic regression analysis was used to analyze the independent risk factors for occurring AKI in patients with ischemic stroke.ResultsA total of 214 patients with ischemic stroke were enrolled, including 32 (14.95%) had AKI and 182 (85.05%) did not have AKI.The proportions of patients in heart failure (62.50% vs.41.21%;χ2=4.998, P=0.025), mannitol use (87.50% vs.43.96%;χ2=20.643, P200 ml (28.13% vs.9.89%;χ2=6.637, P=0.010), as well as NIHSS score (18.0±4.5)vs.8.0±3.2;t=15.249, P200 ml (OR 3.294, 95% CI 1.464-2.786;P=0.021) were the independent risk factors for AKI in patients with acute ischemic stroke.ConclusionsThe NIHSS score, diastolic blood pressure, arterial lactate concentration,mannitol use, furosemide use, contrast agent use and contrast dosage >200 ml were associated with AKI in patients with ischemic stroke.
