研究目的:

探究对于急性缺血性卒中伴溶栓前血压高于所在地区指南建议范围(中国指南:180/100 mmHg;美国/欧洲指南185/110 mmHg)的患者,同时启动静脉溶栓及降压治疗相较于先将血压降至建议范围再进行溶栓的有效性与安全性研究。  

Objectives of Study:

To investigate the efficacy and safety of initiating intravenous thrombolysis concurrently with antihypertensive treatment, compared with lowering blood pressure to the guideline-recommended range (China: 180/100 mmHg; US/Europe: 185/110 mmHg) before thrombolysis, in patients with acute ischemic stroke whose pre-thrombolysis blood pressure exceeds these thresholds.

组别:

同时溶栓组

样本量:

800

Group:

Concurrent Arm

Sample size:

干预措施:

1.溶栓治疗:随机分组后立即按照当地常规实施静脉溶栓(阿替普酶或替奈普酶); 2.降压治疗:在开始静脉溶栓治疗后的同时(在可行的情况下),启动静脉降压治疗,目标是将血压降低至低于指南推荐的范围(例如:中国为 180/100 mmHg;美国/加拿大/欧洲为 185/110 mmHg)

干预措施代码:

Intervention:

1.Thrombolysis: Immediately after randomization, intravenous thrombolysis (alteplase or tenecteplase, per local standard of care) is administered as per local practice. 2.Antihypertensive Therapy: Intravenous antihypertensive therapy is initiated concurrently with the start of intravenous thrombolysis, as soon as feasible, with the goal of lowering blood pressure to below the guideline-recommended range (e.g., China: 180/100 mmHg; U.S./Canada/Europe: 185/110 mmHg).

Intervention code:

组别:

延迟溶栓组

样本量:

800

Group:

Sequential Arm

Sample size:

干预措施:

1.降压治疗:随机分组后立即启动静脉降压治疗,积极将血压降至指南推荐范围以下; 2.溶栓治疗:一旦确认血压达到或低于指南范围,立即进行静脉溶栓(阿替普酶或替奈普酶,依据当地常规)。

干预措施代码:

Intervention:

1.Antihypertensive Therapy: Immediately after randomization, intravenous antihypertensive therapy is initiated to actively lower the patient's blood pressure to below the guideline recommended range. 2.Thrombolysis: Once the blood pressure is confirmed to be at or below the guideline recommended range, intravenous thrombolysis (alteplase or tenecteplase, per local standard of care) is administered.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于干预措施涉及用药时序,患者及急救治疗团队知晓分组(开放标签设计)。为降低结局评估偏倚,以下人员将严格盲法: 1)结局评估员: 负责进行90天随访及改良Rankin量表(mRS)评估的认证评估员; 2)中央影像核心实验室的神经科与影像科医师: 负责判定所有影像学终点,包括症状性颅内出血(sICH)。

Blinding:

The intervention is open-label for the patient and the acute-care clinical team due to the procedural nature of medication timing. To minimize bias in outcome ascertainment, the following personnel will be strictly blinded to the patient's treatment allocation: The certified outcome assessors who conduct the 90-day outcome assessments including the modified Rankin Scale (mRS) assessment. The neurologists and radiologists at the central imaging core laboratory who are responsible for adjudicating all imaging endpoints, including symptomatic intracerebral hemorrhage (sICH).
