- Objectives: Evidence of endovascular treatment (EVT) for acute large vessel occlusion (LVO) ischemic stroke in patients harboring substantial prestroke disability is lacking due to their exclusion from randomized trials. Here, we used routine care observational data to compare outcomes in patients with and without prestroke disability receiving EVT for LVO ischemic stroke. Methods: Consecutive patients undergoing EVT for acute LVO ischemic stroke at the Sahlgrenska University Hospital from January 1st, 2015 to March 31st, 2018 were registered in the Sahlgrenska Stroke Recanalization Registry. Pre- and poststroke functional levels were assessed by the modified Rankin Scale (mRS). Outcomes were recanalization rate (mTICI = 2b/3), symptomatic intracranial hemorrhage [sICH], complications during hospital stay, and return to prestroke functional level and mortality at 3 months. Results: Among 591 patients, 90 had prestroke disability (mRS ≥ 3). The latter group were older, more often female, had more comorbidities and higher NIHSS scores before intervention compared to patients without prestroke disability. Recanalization rates (80.0% vs 85.0%, p = 0.211), sICH (2.2% vs 6.3% p = 0.086) and the proportion of patients returning to prestroke functional level (22.7% vs 14.8% p = 0.062) did not significantly differ between those with and without prestroke disability. Patients with prestroke disability had higher complication rates during hospital stay (55.2% vs 40.1% p < 0.01) and mortality at 3 months (48.9% vs 24.3% p < 0.001). Conclusion: One of five with prestroke disability treated with thrombectomy for a LVO ischemic stroke returned to their prestroke functional level. However, compared to patients without prestroke disability, mortality at 3 months was higher. © 2020, The Author(s).

- Background: Time delay from stroke onset to hospital arrival is an important obstacle to recanalization therapy. To increase knowledge about stroke symptoms and potentially reduce delayed hospital arrival, a 27-month national public information campaign was conducted in Sweden. Aim: To assess the effects of a national stroke campaign in Sweden. Methods: This nationwide study included 97,840 patients with acute stroke, admitted to hospital and registered in the Swedish Stroke Register from 1 October 2010 to 31 December 2014 (one year before the campaign started to one year after the campaign ended). End points were (1) proportion of patients arriving at hospital within 3 h of stroke onset and (2) the proportion < 80 years of age receiving recanalization therapy. Results: During the campaign, both the proportion of patients arriving at hospital within 3 h (p < 0.05) and the proportion receiving recanalization therapy (p < 0.001) increased. These proportions remained stable the year after the campaign, and no significant improvements with respect to the two end points were observed during the year preceding the campaign. In a multivariable logistic regression model comparing the last year of the campaign with the year preceding the campaign, the odds ratio of arriving at hospital within 3 h was 1.05 (95% confidence interval (CI): 1.00–1.09) and that of receiving recanalization was 1.34 (95% CI: 1.24–1.46). Conclusion: The Swedish National Stroke Campaign was associated with a sustained increase in the proportion of patients receiving recanalization therapy and a small but significant improvement in the proportion arriving at hospital within 3 h.

- BackgroundTime delay from stroke onset to arrival in hospital is an important obstacle to widespread reperfusion therapy. To increase knowledge about stroke, and potentially decrease this delay, a 27-month national public information campaign was carried out in Sweden. MethodsThe variables used to measure campaign effects were knowledge of the AKUT test [a Swedish equivalent of the FAST (Face-Arm-Speech-Time)] test and intent to call 112 (emergency telephone number) . Telephone interviews were carried out with 1500 randomly selected people in Sweden at eight points in time: before, three times during, immediately after, and nine, 13 and 21months after the campaign. ResultsBefore the campaign, 4% could recall the meaning of some or all keywords in the AKUT test, compared with 23% during and directly after the campaign, and 14% 21months later. Corresponding figures were 15%, 51%, and 50% for those remembering the term AKUT and 65%, 76%, and 73% for intent to call 112 when observing or experiencing stroke symptoms. During the course of the campaign, improvement of stroke knowledge was similar among men and women, but the absolute level of knowledge for both items was higher for women at all time points. ConclusionThe nationwide campaign substantially increased knowledge about the AKUT test and intention to call 112 when experiencing or observing stroke symptoms, but knowledge declined post-intervention. Repeated public information therefore appears essential to sustain knowledge gains.

- Objective/Background: The aim of the Carotid Alarm Study was to compare the procedural risk of carotid endarterectomy (CEA) performed within 48 hours with that after 48 hours to 14 days following an ipsilateral cerebrovascular ischaemic event. Methods: Consecutive patients with symptomatic carotid stenosis undergoing CEA were prospectively recruited. Time to surgery was calculated as time from the most recent ischaemic event preceding surgery. A neurologist examined patients before and, after CEA. The primary endpoint was the composite endpoint of death and/or any stroke within 30 days of the surgical procedure. The study was designed to include 600 patients, with 150 operated on within 48 hours. Results: From October 2010 to December 2015, 418 patients were included, of whom 75 were operated within 48 hours of an ischaemic event. The study was prematurely terminated owing to the slow recruitment rate in the group operated on within 48 hours. Patients undergoing CEA within 48 hours had a higher risk of reaching the primary endpoint than those operated on later (8.0% vs. 2.9%). Multivariate logistic regression analyses showed that CEA performed within 48 h (odds ratio [OR] 3.07; 95% confidence interval [CI] 1.04-9.09), CEA performed out of office hours (OR 3.65; 95% CI 1.14-11.67), and use of shunt (OR 4.02; 95% CI 1.36-11.93) were all independently associated with an increased risk of reaching the primary endpoint. Conclusion: CEA performed within 48 hours was associated with a higher risk of complications compared with surgery performed 48 hours-14 days after the most recent ischaemic event.
