Abstract  

Objective: To investigate the effect of treatment time on the outcome of patients with ischemic stroke undergoing reperfusion therapy. Methods: The clinical data of 3229 ischemic stroke patients who received intravenous thrombolysis with or without arterial thrombolysis from 71 hospitals in Zhejiang province from June 2017 to September 2018 were retrospectively reviewed. The good outcome was defined as modified Rankin Scale (mRS) ≤ 2. Binary logistic regression analysis was used to investigate the association of door to needle time (DNT), or door to reperfusion time (DRT) with the outcomes in patients treated by intravenous thrombolysis or bridging arterial thrombolysis, respectively. Results: Binary logistic regression showed that DNT (OR=0.994, 95%CI:0.991-0.997, P < 0.01) or DRT (OR=0.989, 95%CI:0.983-0.995, P < 0.01) were independently associated with good outcomes, respectively. Every hour decreases in DNT resulted in a 4.7%increased probability of functional independence (mRS 0-2) in patients treated by intravenous thrombolysis; Every hour decreases in DRT was associated with a 11.4%increased probability of functional independence in patients treated by intravenous thrombolysis with arterial thrombolysis. Conclusion: Good outcomes are associated with lower DNT in ischemic stroke patients treated by intravenous thrombolysis or lower DRT in patients treated by intravenous thrombolysis bridging arterial thrombolysis.

治疗时间提前可改善缺血性脑卒中患者再灌注治疗的预后

目的: 探究缺血性脑卒中患者再灌注治疗时间与预后的关系。方法: 纳入2017年6月至2018年9月在浙江省卒中急救平台上报的71家医院中接受单纯静脉溶栓或者桥接动脉取栓治疗的缺血性脑卒中患者3229例。3个月改良Rankin量表(mRS)2分及以下为预后良好。采用二元Logistic回归分析法研究入院至溶栓时间(DNT)、入院至再灌注时间(DRT)与患者治疗后3个月预后的关系。结果: DNT和DRT分别是单纯静脉溶栓治疗、静脉溶栓桥接动脉取栓治疗患者预后的独立影响因素(OR=0.994,95%CI:0.991~0.997,P < 0.01;OR=0.989,95%CI:0.983~0.995,P < 0.01)。对于单纯静脉溶栓治疗的患者,DNT每减少1 h,3个月预后良好的比例提高约4.7%;而对于静脉溶栓桥接动脉取栓治疗的患者,DRT每减少1 h,3个月预后良好的比例提高约11.4%。结论: 缩短时间窗内缺血性脑卒中患者的DNT或DRT,可以不同程度地提高患者再灌注治疗3个月预后良好的比例。
