Abstract:
Objective To investigate the correlation between plasma cathepsin L (CatL) levels and establishment of cerebral collateral circulation in acute ischemic stroke patients with cerebral artery stenosis.Methods The patients with acute ischemic stroke with at least one cerebral large artery (including internal carotid artery,middle cerebral artery,vertebral artery,and basilar artery) stenosis ＞ 70％ diagnosed by whole cerebral angiography were enrolled.ASITN/SIR blood flow classification system was used to systematically evaluate the establishment of cerebral collateral circulation.Grade 0-2 was defined as poor collateral branch and 3-4 was defined as good collateral branch,Enzyme linked immunosorbent assay was used to detect the plasma CatL level.Results A total of 79 acute ischemic stroke patients with cerebral artery stenosis were enrolled,including 63 male and 16 female.Their mean age was 58.76 ± 12.24 years old.There were 51 patients (64.56％) in the poor collateral branch group and 28 (35.44％) in the good collateral branch group.There was no significant difference in plasma CatL levels between the good collateral circulation group and the poor collateral circulation group (7.09± 2.27 mg/L vs.8.79±3.53 mg/L;t =2.751,P =0.069).Multivariable logistic regression analysis showed that only the high National Institutes of Health Stroke Scale score was the independent risk factor for poor collateral circulation (odds ratio 0.935,95％ confidence interval 0.823-0.963;P=0.046),and there was no significant independent correlation between plasma CatL levels and collateral circulation (odds ratio 0.910,95％ confidence interval 0.766-1.081;P =0.285).Conclusion There was no significant correlation between plasma CatL levels and cerebral collateral development in acute ischemic stroke patients with cerebral artery stenosis.
