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). |
