Abstract:
Objective:To investigate the effect and predictive value of plasma apolipoprotein A1(ApoA1)/apoli-poprotein B(ApoB)ratio on early cerebral infarction(CI)after transient ischemic attack(TIA).Methods:A total of 147 TIA patients who were hospitalized in the Neurology or Emergency Department of Affiliated Hospital of North China University of Science and Technology from September 2018 to May 2021 were retrospectively collect-ed.According to presence of cerebral infarction within 7d,they were divided into CI group(n=65)and no CI group(n=82).Immunoturbidimetry was used to detect plasma ApoA1 and ApoB levels,then ApoA1/ApoB ratio was calculated;ROC curve was used to analyze the predictive value of plasma ApoA1/ApoB ratio for early CI after TIA;Logistic regression was used to analyze influencing factors of early CI after TIA.Results:Compared with no CI group,CI group had significantly higher proportions of hyperlipidemia history(52.44％vs.69.23％),stroke history(36.59％vs.55.38％),intracranial artery stenosis(21.95％vs.38.46％)and cerebral ischemia duration≥30min(51.22％vs.73.85％),levels of triglyceride[(1.27±0.48)mmol/L vs.(1.65±0.53)mmol/L]and fast-ing blood glucose[FBG:(5.43±1.52)mmol/L vs.(6.05±1.65)mmol/L](P＜0.05 or＜0.01);significant lower plasma ApoA1 level[(1.35±0.32)g/L vs.(1.07±0.30)g/L]and ApoA1/ApoB ratio[(1.52±0.34)vs.(1.03±0.31)]and significant higher ApoB level[(0.85±0.23)g/L vs.(1.04±0.27)g/L](P＜0.001 all).Sen-sitivity and specificity of plasma ApoA1/ApoB ratio predicting early CI after TIA was 86.15％and 82.93％respec-tively,the area under the curve was 0.884(95％CI 0.821～0.931,P＜0.001)and cutoff value was 1.33.Multi-variate Logistic regression analysis suggested that hyperlipidemia,stroke history,intracranial artery stenosis,FBG＞6.1 mmol/L and cerebral ischemia duration＞30min were independent risk factors for early CI after TIA(OR=1.128～6.613,P＜0.05 or＜0.01),while ApoA1/ApoB ratio＞1.33 was its independent protective factor(OR=0.005,P＜0.001).Conclusion:Plasma ApoA1/ApoB ratio significantly decreases in patients with cerebral infarc-tion after TIA,which is a factor affecting early cerebral infarction after TIA,and it has certain predictive value for it.
