Background For patients with stroke with large-vessel occlusion (LVO), study of factors predicting response to intravenous thrombolysis (IVT) would allow identifying subgroups with high expected gain, and those for whom it could be considered as futile, and even detrimental. From patients included in the Mechanical Thrombectomy After Intravenous Alteplase vs Alteplase Alone After Stroke trial, we investigated clinical-imaging factors associated with optimal response to IVT. Methods We included patients receiving IVT alone. Excellent outcome was defined by a 3-month modified Rankin Scale (mRS) score ≤1. Clinical-imaging predictors were assessed on multivariate analysis after multiple imputations. The predictive performance of the model was assessed with the C-statistic. Results Among 247 patients with LVO treated with IVT alone, 77 (31%) showed 3-month mRS ≤1. Predictors of 3-month mRS ≤1 were no medical history of hypertension (OR 2.43; 95% CI 1.74 to 3.38; p=0.007); no current smoking (OR 2.76; 95% CI 1.79 to 4.26; p=0.02); onset-to-IVT time (OR 0.47 per hour increase; 95% CI 0.23 to 0.78; p=0.003); diffusion-weighted imaging (DWI) volume (OR 0.78 per 10 mL increase; 95% CI 0.68 to 0.89; p=0.0004); presence of susceptibility vessel sign (SVS) (OR 7.89; 95% CI 1.65 to 37.78; p=0.01) and SVS length (OR 0.87 per mm increase; 95% CI 0.80 to 0.94; p=0.001). The prediction models showed a C-statistic=0.79 (95% CI 0.79 to 0.80). Conclusions In patients with stroke with anterior-circulation LVO treated with IVT alone, predictors of excellent outcome at 3 months were no medical history of hypertension or current smoking, reduced onset-to-IVT time, small DWI volume, presence of SVS and short SVS length. These predictive factors could help practitioners in decision-making for IVT implementation in reperfusion strategies, all the more for the drip and ship paradigm.

大血管卒中溶栓后预后良好的临床影像学因素:THRACE亚组分析

背景 对于伴有大血管闭塞 (LVO) 的卒中患者,研究预测对静脉溶栓 (IVT) 的反应的因素将有助于识别具有高预期收益的亚组,以及那些可能被视为徒劳甚至有害的亚组。我们从纳入静脉阿替普酶后机械血栓切除术与中风后单独阿替普酶试验的患者中,调查了与 IVT 最佳反应相关的临床影像学因素。方法 我们纳入了单独接受 IVT 的患者。3 个月改良 Rankin 量表 (mRS) 评分≤1 定义了优异的结果。在多次插补后,通过多变量分析评估临床影像学预测因子。使用 C 统计量评估模型的预测性能。结果 在 247 例仅接受 IVT 治疗的 LVO 患者中,77 (31%) 显示 3 个月 mRS ≤1。3 个月 mRS ≤1 的预测因素是没有高血压病史(OR 2.43;95% CI 1.74 至 3.38;p=0.007);目前不吸烟(OR 2.76;95% CI 1.79 至 4.26;p=0.02);起效至 IVT 时间(OR 每小时增加 0.47;95% CI 0.23 至 0.78;p=0.003);弥散加权成像 (DWI) 体积(OR 0.78 每增加 10 mL;95% CI 0.68 至 0.89;p=0.0004);存在易感血管征 (SVS) (OR 7.89;95% CI 1.65 至 37.78;p=0.01) 和 SVS 长度 (OR 0.87 每增加毫米;95% CI 0.80 至 0.94;p=0.001)。预测模型显示 C 统计量 = 0.79(95% CI 0.79 至 0.80)。结论 在单纯 IVT 治疗的前循环 LVO 卒中患者中,3 个月时预后良好的预测因素是无高血压病史或当前吸烟、开始 IVT 时间缩短、DWI 体积小、存在 SVS 和短 SVS 长度。这些预测因素可以帮助从业者在再灌注策略中进行 IVT 实施决策,对于滴灌和运输模式更是如此。试用注册号 [NCT01062698][1]。可根据合理要求提供数据。只有与该辅助研究的主要目标相关的数据才能从 THRACE 试验中获得,并与该试验的主要研究者一致。在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 这些预测因素可以帮助从业者在再灌注策略中进行 IVT 实施决策,对于滴灌和运输模式更是如此。试用注册号 [NCT01062698][1]。可根据合理要求提供数据。只有与该辅助研究的主要目标相关的数据才能从 THRACE 试验中获得,并与该试验的主要研究者一致。在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 这些预测因素可以帮助从业者在再灌注策略中进行 IVT 实施决策,对于滴灌和运输模式更是如此。试用注册号 [NCT01062698][1]。可根据合理要求提供数据。只有与该辅助研究的主要目标相关的数据才能从 THRACE 试验中获得,并与该试验的主要研究者一致。在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 试用注册号 [NCT01062698][1]。可根据合理要求提供数据。只有与该辅助研究的主要目标相关的数据才能从 THRACE 试验中获得,并与该试验的主要研究者一致。在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 试用注册号 [NCT01062698][1]。可根据合理要求提供数据。只有与该辅助研究的主要目标相关的数据才能从 THRACE 试验中获得,并与该试验的主要研究者一致。在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom 在对主要目标的解释和统计分析之后,共享了个人去识别的参与者数据。数据可根据 SR (s.richard@chru-nancy.fr) 的合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT01062698&atom=%2Fsvnbmj%2F6%2F4%2F631.atom
