Book excerpt: ObjectiveSeizure at onset (SaO) has been considered a relative contraindication for intravenous thrombolysis (IVT) in patients with acute ischemic stroke, although this appraisal is not evidence-based. Here, we investigated the prognostic significance of SaO in patients treated with IVT for suspected ischemic stroke. MethodsIn this multicenter, IVT-registry-based study we assessed the association between SaO and symptomatic intracranial hemorrhage (sICH, ECASS-II definition), 3-month mortality and 3-month functional outcome on the modified Rankin Scale (mRS) using unadjusted and adjusted logistic regression, coarsened exact matching and inverse probability weighted analyses. ResultsAmong 10,074 IVT-treated patients, 146 (1.5%) had SaO. SaO patients had significantly higher NIHSS and glucose on admission and more often female sex, prior stroke and prior functional dependence than non-SaO patients. In unadjusted analysis, they had generally less favorable outcomes. After controlling for confounders in adjusted, matched and weighted analyses, all associations between SaO and any of the outcomes disappeared, including sICH (odds ratio [OR]unadjusted 1.53 [95% confidence interval: 0.74,3.14], ORadjusted 0.52[0.13,2.16], ORmatched 0.68[0.15,3.03], ORweighted 0.95[0.39,2.32]), mortality (ORunadjusted 1.49[1.00,2.24], ORadjusted 0.98[0.5,1.92], ORmatched 1.13[0.55,2.33], ORweighted 1.17[0.73,1.88]) and functional outcome (mRSu22653 / ordinal mRS: ORunadjusted 1.33[0.96,1.84] / 1.35[1.01,1.81], ORadjusted 0.78[0.45,1.32] / 0.78[0.52,1.16], ORmatched 0.75[0.43,1.32] / 0.45[0.10,2.06], ORweighted 0.87[0.57,1.34] / 1.00[0.66,1.52]). These results were consistent regardless of whether patients had an eventual diagnosis of ischemic stroke (89/146) or stroke mimic (57/146 SaO patients). InterpretationSaO was not an independent predictor of poor prognosis. Withholding IVT from patients with assumed ischemic stroke presenting with SaO seems unjustified.
