• W3136256685 abstract "Introduction: Current guidelines recommend that patients given intravenous tPA (IV tPA) for acute ischemic stroke (AIS) receive comprehensive stroke care for 24 hours post-treatment to monitor key physiologic variables. 1,2,3 Early de-escalation of monitoring is likely feasible in a particular subset of patients, which may have implications in the post-COVID era. 4 In this study, we examined when patients with AIS are susceptible to early neurologic decline (END) and symptomatic intracranial hemorrhage (sICH) after IV tPA and whether those at low clinical risk of neurologic deterioration may be suitable for earlier transition to lower level of care. Methods: We performed a retrospective analysis of AIS receiving IV tPA based on AHA/ASA guidelines. We included those that presented within 4.5 hours of last seen well (LSW) without large vessel occlusion (LVO) or flow-limiting stenosis (FLS) on non-invasive angiographic imaging. Outcomes included END (≥4-point worsening of NIHSS at 24 hours) from any cause, parenchymal hemorrhage (PH1 or PH2), and/ or symptomatic intracranial hemorrhage (sICH; ≥4-point NIHSS worsening with presence of hemorrhage). Results: 1238 patients were included from 1/2013 - 6/2019. END and ICH occurred in 7.4% (91) and 9.4% (116), respectively. 63.7% of patients with END did not have ICH within 24 hours. In those with NIHSS <12, 82% had END within 12 hours and most occurred within 5 hours. Predictive factors included older patients (72.6 ±16.1 vs 69.1 ±14.8, p=0.03), history of tobacco use (OR-2.1 [1.1-4.3], p = 0.04) and hyperlipidemia (OR-1.7 [1.1-2.8] p = 0.02). ICH occurred within 12 hours in 30% of patients, predictors included older age (74.6 ± 12.4 vs 68.8 ± 15.1, p ≤ 0.01), higher NIHSS (14.6 ± 7.3 vs 10.8 ± 7.9, p ≤ 0.01), and higher presentation serum glucose levels (155.1 ± 87.5 vs 140.4 ± 70.5, p = 0.04). Overall, only 2.7% (33) of patients developed sICH. There were no independent predictive factors for delayed ICH (≥ 12 hours). Conclusion: In our selected post-IV tPA patients, a relatively small proportion suffered sICH and END; most often within 12 hours of tPA administration. These findings may support earlier de-escalation of higher acuity monitoring for clinically stable post-IV tPA patients." @default.
