Four randomized clinical trials, including the OPTIMAL-BP trial, have examined blood pressure control following thrombectomy. Meta-analyses showed that intensive BP lowering did not reduce symptomatic hemorrhage and was associated with worse functional outcomes at 3 months. Specifically, lowering BP too aggressively after successful reperfusion could worsen outcomes by reducing perfusion to the ischemic penumbra. Therefore, this study will investigate whether a more targeted blood pressure elevation strategy could improve patient prognosis compared to standard BP control in patients with sustained systolic blood pressure (SBP) <150 mmHg on successive measurements obtained less than 10 minutes apart within 3 hours after reperfusion.
