Abstract
Background
The optimal blood pressure (BP) management following successful endovascular treatment (EVT) in acute ischaemic stroke (AIS) patients remains unclear. This study investigated the safety and efficacy of intensive BP control in AIS patients who had received EVT within 6 h.
Methods
This randomised, multicentre, open-label, blinded-endpoint clinical trial (ChiCTR2200057770) was conducted at 63 stroke centres in China. Eligible participants had AIS due to large vessel occlusion in anterior circulation, underwent EVT within 6 h, and achieved successful recanalisation. Patients were randomised to intensive (systolic BP target <130 mm Hg) or standard (systolic BP target <180 mm Hg) management, maintained until 24 h post-EVT. The primary outcome was unfavourable functional outcome (modified Rankin Scale score of 3–6) at 90 days. The trial was terminated following a neutral interim analysis results and publication of counterpart randomised trials.
Findings
Between October 14, 2022 and March 18, 2024, 383 patients were randomised. Unfavourable functional outcome occurred in 71.0% (130/183) of the intensive-management group and 67.5% (135/200) of the standard-management group (risk ratio, 1.05; 95% CI, 0.92–1.20; p = 0.45). There was no significant difference in symptomatic intracerebral haemorrhage, malignant brain oedema, or all-cause death at 90 days.
Interpretation
Intensive BP management to <130 mm Hg did not improve outcomes in AIS patients undergoing EVT within 6 h and achieved successful recanalisation. The optimal BP management strategies require further investigation.
