Background Data based on randomized clinical trials regarding the efficacy and safety of intravenous thrombolysis (IVT) versus placebo or any other antithrombotic agent in the treatment of stroke associated with atrial fibrillation (AF) are unavailable.; Methods Prospectively collected data on AF-associated stroke patients treated in a 3-year period were analyzed to assess the effect of IVT treatment. Outcome measures were modified Rankin Scale (mRS) score for functional outcome, death, and symptomatic intracerebral hemorrhage (sICH).; Results Of 787 patients diagnosed with an acute ischemic stroke in the observed period, 131 (16.6%) had AF. Multivariate logistic regression analysis after adjustment for confounders demonstrated that independent predictors of excellent outcome (mRS 0-1) in patients with AF-associated stroke were lower baseline National Institutes of Health Stroke Scale [NIHSS] score (adjusted odds ratio [adjOR],.87; 95% confidence interval [CI], 0.81-.94; P =.000) and the use of IVT (adjOR, 5.31; 95% CI, 1.90-14.82; P =.001), whereas independent predictors of death were higher baseline NIHSS score (adjOR, 1.07; 95% CI, 1.02-1.12; P =.003), previous stroke (adjOR, 4.11; 95% CI, 1.49-11.35; P =.006), absence of IVT use (adjOR,.19; 95% CI,.05-.77; P =.021), sICH (adjOR, 18.52; 95% CI, 1.59-215.37; P =.020), and higher serum glucose levels (adjOR, 1.26; 95% CI, 1.06-1.50; P =.008). Thrombolyzed patients with AF were less severe at baseline and were less likely to have NIHSS >18. They were more likely to have excellent and good functional outcome (mRS 0-2) whereas less likely to have death as outcome at 3 months. Thrombolyzed AF patients had constantly lower probability of death regardless of the baseline NIHSS score values.; Conclusions These results should encourage the use of IVT in AF-associated strokes. © 2014 National Stroke Association.

Objective There are no data regarding long-term medication persistence in stroke survivors treated with intravenous thrombolysis (IVT), which is one of the most important determinants of treatment success. Our objective was to determine long-term medication persistence in stroke patients treated with IVT. Methods This retrospective observational study included 203 IVT-treated and 197 non-IVT treated patients with acute ischemic strokes (IS) admitted to the Stroke Unit between January 2007 and January 2013. Results During a median follow-up period of 3 years (range 1-7 years), 56 (21.6%) patients in the IVT-group and 62 (23.9%) patients in the non-IVT-group died. There was a higher medication persistence for all secondary stroke prevention medications (anti-thrombotic agents, anti-hypertensive drugs, statins and hypoglycemic drugs) in the IVT-group compared to the non-IVT group (88.7% vs. 69.0%; OR = 3.68, 95% CI = 2.17-6.23). After adjusting for baseline characteristics and possible confounders IVT was the independent predictor of medication persistence (OR = 2.93, 95% CI = 1.48-5.81, p = 0.002). Higher medication persistence was observed in patients with favorable long-term functional outcome, both in the IVT-group (OR = 4.37, 95% CI = 1.83-10.40, p < 0.001) and the non-IVT-group (OR = 3.46, 95% CI = 1.84-6.52, p < 0.001). Conclusion Medication persistence was higher among IVT-treated patients compared to non-IVT-treated patients. The higher rate of non- medication persistence was recorded among patients with more pronounced disabilities after stroke. © 2015 Published by Elsevier B.V.

Background and Purpose It remains unclear if intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator has an impact on the survival and maintenance of a favorable effect on functional recovery over a long follow-up period. The aim of this study was to assess whether or not IVT treatment has a favorable effect on functional recovery and survival less than 1 year after a stroke. Methods This matched cohort study included 259 patients with acute ischemic stroke (IS) who were treated with IVT and standard care and 259 patients treated with standard care alone in the stroke unit between February 2006 and January 2013. Results After a median follow-up period of 3 years (range, 1-7 years), survival did not differ significantly between the groups; specifically, 56 patients (21.6%) in the thrombolysed group died versus 62 patients (23.94%) in the nonthrombolysed group (log-rank, .240, P = .624). Based on a multivariate Cox proportional hazards regression model, older age (>70 years), stroke severity (National Institutes of Health Stroke Scale score ≥ 15), diabetes mellitus, and a history of atrial fibrillation were independent predictors of long-term mortality after stroke. After the follow-up period, 144 patients (55.6%) in the IVT-treated group versus 112 patients (43.2%) in the control group had an excellent outcome, with a modified Rankin Scale score of 0-1 (hazard ratio [HR] = 1.64, 95% confidence interval [CI] = 1.16-2.32). Based on a multivariate Cox proportional hazards regression model, an excellent 3-month functional recovery was a strong predictor of favorable outcome (HR = 11.27, 95% CI = 6.45-19.63). Conclusion The results suggest that IVT for acute IS has a favorable effect on functional recovery more than 1 year after stroke. © 2017 National Stroke Association

Objective: To investigate the prognostic value of white blood cell count (WBC) on functional outcome, mortality and bleeding risk in stroke patients treated with intravenous thrombolysis (IVT). Methods: In this prospective multicenter study from the TRISP registry, we assessed the association between WBC on admission and 3-month poor outcome (modified Rankin Scale 3–6), mortality and occurrence of symptomatic intracranial hemorrhage (sICH; ECASS-II-criteria) in IVT-treated stroke patients. WBC was used as continuous and categorical variable distinguishing leukocytosis (WBC > 10 × 109/l) and leukopenia (WBC < 4 × 109/l). We calculated unadjusted/ adjusted odds ratios with 95% confidence intervals (OR [95% CI]) with logistic regression models. In a subgroup, we analyzed the association of combined leukocytosis and elevated C-reactive protein (CRP > 10 mg/l) on outcomes. Results: Of 10,813 IVT-treated patients, 2527 had leukocytosis, 112 leukopenia and 8174 normal WBC. Increasing WBC (by 1 × 109/l) predicted poor outcome (ORadjusted 1.04[1.02–1.06]) but not mortality and sICH. Leukocytosis was independently associated with poor outcome (ORadjusted 1.48[1.29–1.69]) and mortality (ORadjusted 1.60[1.35–1.89]) but not with sICH (ORadjusted 1.17[0.94–1.45]). Leukopenia did not predict any outcome. In a subgroup, combined leukocytosis and elevated CRP had the strongest association with poor outcome (ORadjusted 2.26[1.76–2.91]) and mortality (ORadjusted 2.43[1.86–3.16]) when compared to combined normal WBC and CRP. Conclusion: In IVT-treated patients, leukocytosis independently predicted poor functional outcome and death. Bleeding complications after IVT were not independently associated with leukocytosis. © 2022, The Author(s).
