研究目的:

1. 主要目的:比较血管内取栓后24小时内,积极降压策略(目标SBP 140 mmHg)与限制性管理策略(目标SBP 140~180 mmHg)对基线收缩压>140 mmHg的急性大血管闭塞性缺血性脑卒中患者90天功能独立率(mRS评分0-2分)的影响,验证限制性管理策略的优效性。 2. 次要目的: (1) 评估两种血压管理策略对灌注治疗后早期并发症(神经功能恢复、颅内出血、卒中复发、90 天全因死亡率等)发生风险的影响; (2) 评估收缩压维持在设定目标区间内的累计时长比例(TimeinTargetRange,TTR)、降压药物使用情况、血压变异性(BPV)等过程指标与预后的关系。  

Objectives of Study:

1. Primary objective: To compare the effects of an intensive antihypertensive strategy (targeting systolic blood pressure [SBP] <140 mmHg) versus a conservative management strategy (targeting SBP 140–180 mmHg) within 24 hours after endovascular thrombectomy on the 90-day rate of functional independence (defined as a modified Rankin Scale [mRS] score of 0–2) in patients with acute ischemic stroke due to large vessel occlusion and a baseline SBP >140 mmHg, and to test the superiority of the conservative management strategy. 2. Secondary objective: (1) To evaluate the impact of two blood pressure management strategies on the risk of early complications following reperfusion therapy (including neurological recovery, intracranial hemorrhage, stroke recurrence, and 90-day all-cause mortality); (2) To assess the association between prognostic outcomes and process measures, such as the proportion of time within the target systolic blood pressure range (Time in Target Range, TTR), antihypertensive medication usage, and blood pressure variability (BPV).

干预措施:

Interventions:

组别:

限制性血压管理组

样本量:

528

Group:

Conservative BP management group

Sample size:

干预措施:

限制性血压管理策略:术后24小时内,原则上不启动降压药物。仅当收缩压持续>180 mmHg(连续3次测量,间隔5分钟)时,启动静脉乌拉地尔,将收缩压控制在<180 mmHg,并尽快尝试停药,恢复以监测为主的策略。目标范围140-180 mmHg。

干预措施代码:

Intervention:

Restrictive blood pressure management strategy: In principle, antihypertensive drugs should not be initiated within 24 hours after the operation. Only when systolic blood pressure persists When the systolic blood pressure > 180 mmHg (measured three times in a row with a 5-minute interval), intravenous urapidil is initiated to control the systolic blood pressure <180 mmHg, try to stop the medication as soon as possible and resume a monitoring-based strategy. The target range is 140-180 mmHg.

Intervention code:

组别:

积极降压组

样本量:

528

Group:

Intensive antihypertensive group

Sample size:

干预措施:

积极降压策略:术后24小时内使用静脉注射盐酸乌拉地尔,将收缩压平稳控制在140-145 mmHg。启动后1小时内SBP较基线下降10-20 mmHg,后续维持目标范围。若SBP低于130 mmHg或出现低血压症状,暂停降压并处理。

干预措施代码:

Intervention:

Active antihypertensive strategy: Administer urapidil hydrochloride intravenously within 24 hours after the operation to steadily control systolic blood pressure at 140-145 mmHg. Within one hour after initiation, SBP decreased by 10-20 mmHg compared to the baseline, and then maintained within the target range. If SBP is lower than 130 mmHg or hypotension symptoms occur, stop lowering blood pressure and deal with it.
