Results: From a total of 676 participants randomized in the CLOTBUST-ER trial we identified 52 patients from 7 centers with perceived equipoise shift in favor of endovascular treatment. Post hoc sensitivity analysis in the intention-to-treat population adjusted for age, National Institutes of Health Scale score at baseline, time from stroke onset to tPA bolus and baseline serum glucose showed a significant (p < 0.01) interaction of perceived endovascular equipoise shift on the association between sonothrombolysis and 3 month functional outcome [adjusted common odds ratio (cOR) in centers with perceived endovascular equipoise shift: 0.22, 95% CI 0.06–0.75; p = 0.02; adjusted cOR for centers without endovascular equipoise shift: 1.20, 95% CI 0.89–1.62; p = 0.24)]. After excluding centers with perceived endovascular equipoise shift, patients randomized to sonothrombolysis had higher odds of 3 month functional independence (mRS scores 0–2) compared with patients treated with tPA only (adjusted OR: 1.53; 95% CI 1.01–2.31; p = 0.04). Conclusion: Our experience in CLOTBUST-ER indicates that increasing implementation of endovascular therapies across major academic stroke centers raises significant challenges for clinical trials aiming to test noninterventional or adjuvant reperfusion strategies.]]> Thu 09 Dec 2021 11:02:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46103 185/105 mmHg) during the first 24 h following tPA-bolus. The majority of BP excursions (46%) occurred within the first 75 min from tPA-bolus. Patients with at least one BP excursion in the first 24 h following tPA bolus had significantly lower rates of independent functional outcome at 90 days (31 vs. 40.1%, P = 0.028). The total number of BP excursions was associated with decreased odds of 24-h clinical recovery (OR = 0.88, 95% CI:0.80–0.96), 24-h neurological improvement (OR = 0.87, 95% CI: 0.81–0.94), 7-day functional improvement (common OR = 0.92, 95% CI: 0.87–0.97), 90-day functional improvement (common OR = 0.94, 95% CI: 0.88–0.98) and 90-day independent functional outcome (OR = 0.90, 95% CI: 0.82–0.98) in analyses adjusted for potential confounders. DBP excursions were independently associated with increased odds of any intracranial hemorrhage (OR = 1.26, 95% CI: 1.04–1.53). Conclusion: BP excursions above guideline thresholds during the first 24 h following tPA administration for AIS are common and are independently associated with adverse clinical outcomes.]]> Fri 11 Nov 2022 15:33:52 AEDT ]]>
