Correlation between plasma fibronectin and hemorrhagic transformation in patients with acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

Objective To investigate the correlation between plasma fibronectin (Fn) level and the hemorrhagic transformation (HT) in patients with acute ischemic stroke.Methods Patients with acute ischemic stroke,symptom onset within 72 hours,no bleeding at baseline MRI (including gradient echo sequences) and without thrombolytic therapy were recruited prospectively.At 7 - 10 days after symptom onset reexamined MRI.The patients were divided into HT and non-HT groups according to whether they had a hemorrhage or not.The plasma Fn levels in both groups were compared.Logistic regression analysis was used to investigate the predictors of HT.Results A total of 78 patients were included,and among them 11 patients (14.10％ ) showed HT.The proportions of atrial fibrillation (36.4％ vs.9.0％,P =0.012) and cardioembolism (36.4％ vs.6.0％,P =0.021) in the HT group were significantly higher than those in the non-HT group.The baseline mean systolic blood pressure (182.09 ±20.73 mm Hg [ 1 mm Hg=0.133 kPa]vs.161.25 ±26.40)mm Hg,P =0.015),mean diastolic blood pressure (98.00 ± 11.26 mm Hg vs.86.60 ± 15.21 rnm Hg,P =0.020),and plasma Fn level (4 835.04 ± 756.30 μg/L vs.3 849.44 ± 1 289.18 μg/L,P =0.016) were all significantly higher than those in the non-HT group.Multivariate logistic regression analysis showed that plasma Fn level (odds ratio [ OR],1.001,95％ confidence interval [ CI] 1.000 - 1.001,P =0.017) and atrial fibrillation (OR,13.408,95％ CI 1.963 -91.592,P =0.008) were the independent predictors of HT in patients with acute ischemic stroke.Conclusions The plasma Fn level in patients with HT increased significantly.The plasma Fn level can be used as an independent predictor of non-thrombolytic HT after the onset of acute ischemic stroke.
