Résumé
Objective To determine the occurrence and baseline predictive factors of early neurological deterioration ( END) among mild ischemic stroke patients.Methods Mild ischemic stroke patients admitted in the hospital were prospectively enrolled.Univariate and multivariate Logistic recession analyses were used to analyze the demographic data, risk factors of ischemic stroke, clinical, brain imaging and laboratory data.Risk factors of END were identified.Results From June 2012 to August 2013, a total of 319 patients with mild ischemic stroke were enrolled, 45 patients (14.1%) of them experienced END.Univariate analysis showed that baseline NIHSS ( U=3522.000,P=0.000), baseline systolic blood pressure (t=2.871,P=0.004), proportion of symptomatic large artery severe stenosis or occlusion (χ2 =52.564,P=0.000) and proportion of large artery atherosclerosis among TOAST subtypes (χ2 =47.287,P=0.000) in END group were significantly higher than those in non-END group. Multivariate logistic regression analysis showed that baseline systolic blood pressure>142 mmHg (1 mmHg=0.133 kPa) (OR=3.954, 95%CI:1.693-9.236, P=0.001), symptomatic large artery severe stenosis or occlusion (OR=3.170, 95%CI:1.170-8.583, P=0.023) and baseline NIHSS (OR=2.038, 95%CI:1.359-3.057, P=0.001) were associated with END.Conclusions About 14.1% of the mild ischemic stroke patients can occur END.Baseline systolic blood pressure>142 mmHg, symptomatic large artery severe stenosis or occlusion and higher baseline NIHSS were the independent risk factors of END.
