目的 探讨血清心型脂肪酸结合蛋白（H-FABP）、血管生成素-1（Ang-1）在急性大血管闭塞性卒中（AIS-LVO）静脉溶栓桥接支架取栓患者预后中的评估价值。方法 选择2019年1月—2021年5月80例AIS-LVO患者作为研究对象,均接受静脉溶栓桥接支架取栓治疗,检测术前血清H-FABP、Ang-1水平,术后随访90 d将患者分为预后良好组（n=57）与预后不良组（n=23）。结果 两组在高血压、冠心病、心房颤动、急性卒中治疗低分子肝素试验（TOAST）分型、侧支循环、术前H-FABP、术前Ang-1方面存在差异（P<0.05）。多因素 Logistic 回归分析结果显示,高血压、心房颤动、心源性梗死型、侧支循环为0 ~1 级、术前H-FABP≥10.0 ng/L、术前Ang-1<5.25 ng/mL是AIS-LVO静脉溶栓桥接支架取栓患者预后不良的危险因素。术前血清H-FABP预测术后90 d预后不良的AUC为0.728（95%CI：0.368~0.918）,灵敏度、特异度分别为66.68%、58.92%。术前血清Ang-1预测术后90 d预后不良的AUC为0.773（95%CI：0.592~1.129）,灵敏度、特异度分别为70.35%、63.92%。H-FABP联合Ang-1预测术后90 d预后不良的AUC为0.854（95%CI：0.652~0.957）,灵敏度、特异度分别为77.18%、71.82%。结论 静脉溶栓桥接支架取栓治疗AIS-LVO患者的预后受到多种危险因素的影响,其中术前血清H-FABP和Ang-1是具有前景的预后预测因子。

Objective To investigate the prognostic value of serum heart-type fatty acid binding protein（H-FABP）and angiopoietin-1（Ang-1）in patients with acute ischemic stroke-large vessel occlusion（ALS-LVO）undergoing venous thrombolytic bridging stent thrombectomy．Methods A total of 80 patients with ALS-LVO from January 2019 to May 2021 were selected as the study subjects,treated with intravenous thrombolytic bridging stent thrombectomy,and their serum H-FABP and Ang-1 levels were measured before operation．After 90 days of follow-up,the patients were divided into good prognosis group（n=57）and poor prognosis group（n=23）．Results There were significant differences between the two groups in hypertension,coronary heart disease,atrial fibrillation,TOAST classification,collateral circulation,preoperative H-FABP,and preoperative Ang-1（P<0.05）．Multivariate logistic regression analysis showed that hypertension,atrial fibrillation,cardiogenic infarction type,collateral circulation of 0~1 grade,preoperative H-FABP≥10.0 ng/L,preoperative Ang-1<5.25 ng/mL were independent risk factors for poor prognosis of ALS-LVO patients treated with venous thrombolytic bridging stents．The AUC of preoperative serum H-FABP predicting poor prognosis 90 days after operation was 0.728（95%CI：0.368~0.918）,with sensitivity and specificity of 66.68% and 58.92% respectively．The AUC of preoperative serum Ang-1 predicting poor prognosis 90 days after surgery was 0.773（95%CI：0.592~1.129）,with sensitivity and specificity of 70.35% and 63.92% respectively．The AUC predicted by H-FABP combined with Ang-1 for poor prognosis 90 days after operation was 0.854（95%CI：0.652~0.957）,and the sensitivity and specificity were 77.18% and 71.82% respectively．Conclusions The prognosis of patients with ALS-LVO treated with intravenous thrombectomy bridging stent thrombectomy is affected by many risk factors,among which preoperative serum H-FABP and Ang-1 are promising prognostic factors．
