The study found that Delta SBP had a linear relationship with poor outcome after successful reperfusion, and the risk of poor outcome was higher with less reduction from the baseline SBP. Additionally, Delta SBP was associated with intraparenchymal hemorrhage.
BACKGROUND AND PURPOSE: To assess the association between systolic blood pressure change (Delta SBP) at different time intervals after successful reperfusion with radiographic and clinical outcomes. METHODS: This is a post hoc analysis of the BP-TARGET multicenter trial (Blood Pressure Target in Acute Stroke to Reduce Hemorrhage After Endovascular Therapy). Delta SBP was defined as end of procedure SBP minus mean SBP at different time intervals (15-60 minutes, 1-6 hours, and 6-24 hours postprocedure). The primary outcome was the poor functional outcome (90-day modified Rankin Scale score 3-6). RESULTS: We included a total of 267 patients (130 in the intensive treatment group). Compared with patients with favorable outcome, patients with poor outcome had lower Delta SBP (less SBP reduction) at all times intervals. After adjusting for potential confounders including baseline SBP, both Delta SBP15-60M and Delta SBP6-24H were associated with lower odds of poor outcome (adjusted odds ratio per 5 mm Hg SBP reduction, 0.89 [95% CI, 0.81-0.99], and adjusted odds ratio 0.82 [95% CI, 0.73-0.92], respectively). Concerning safety outcomes, patients with intraparenchymal hemorrhage had lower Delta SBP at all time intervals. Delta SBP15-60M was associated with lower odds of any intraparenchymal hemorrhage (adjusted odds ratio per 5 mm Hg SBP reduction 0.91 [95% CI, 0.83-0.99]). Conversely, Delta SBP was not associated with mortality or neurological deterioration at any time interval. CONCLUSIONS: After successful reperfusion, Delta SBP had a linear relationship with poor outcome and the risk of poor outcome was higher with less reduction from the baseline SBP.
